As they get ready for work, Millie makes the bed, and their robotic dog Mickey gently reminds Mr. Clark to take his medicine.\u003C\/p\u003E\u003Cp\u003EOnce at work, Mrs. Clark, a hospital nurse, assigns a personal robot to deliver blood samples to the lab while she talks with a patient. Meanwhile, Mr. Clark catches the morning news while his autonomous car navigates the traffic into the city.\u003C\/p\u003E\u003Cp\u003EAt day\u2019s end, the family returns to a spotlessly clean home courtesy of Millie\u2019s untiring work. The Clark children do math homework with tutoring from Margie, another robot. After a dinner the Clarks prepared based on a menu suggested by Millie, the family enjoys the rest of the evening free from chores. They sleep soundly knowing that Mickey is always alert to any trouble.\u003C\/p\u003E\u003Cp\u003EThis scenario is not a page from a lost \u201cJetsons\u201dscript. It\u2019s likely to be a normal day in the life of a family in as few as 20 years from now, according to robotics experts at the Georgia Institute of Technology.\u003C\/p\u003E\u003Cp\u003EAlready, the global market for personal robots is growing 400 percent a year, says Professor Henrik Christensen, director of the newly formed Robotics and Intelligent Machines Center in the Georgia Tech College of Computing.\u003C\/p\u003E\u003Cp\u003E\u201cPersonal robots are becoming more popular as people want to do more and more with their lives,\u201d Christensen says. \u201cTechnology is making it possible\u2026We live stressful lives now, and we can use technology to take away the boring parts of everyday life.\u201d\u003C\/p\u003E\u003Cp\u003ERobots are not novel technology in industry, the military and even space exploration. But a new generation of intelligent machines called personal robots \u2014 ones that work with and directly for humans, especially in the home, workplace and school \u2014 have begun to emerge only recently. A confluence of smart materials, low-cost, high-speed computing power, better batteries and knowledge of how humans interact with machines is creating an explosion in the market for personal robots, researchers say.\u003C\/p\u003E\u003Cp\u003E\u201cTo have a personal robot that does things you need, you have to have onboard processing, perception, motion and power,\u201dsays roboticist Tucker Balch, an associate professor in the College of Computing.\u201cUntil two or three years ago, you couldn\u2019t put all of that on one small, light platform. Motors and computers take a lot of energy, and the batteries we had couldn\u2019t do the job.\u003C\/p\u003E\u003Cp\u003E\u201cNow, demand for better cell phone and laptop batteries is driving improvements,\u201d Balch adds. \u201cUntil recently, you couldn\u2019t get enough processing power without drawing lots of electricity. Also, robots on the market now have addressed the high power requirements of motors. Finally, we have all the technologies that can support a consumer robot that is not too expensive.\u201d\u003C\/p\u003E\u003Cp\u003EBalch predicts that truly useful, multi-function personal robots will cost between $1,000 and $1,500. Single-purpose robots, such as the Roomba vacuum cleaner already on the market, cost between $150 and $300.\u003C\/p\u003E\u003Cp\u003EWhile some personal robots are already available, important research is under way to address the remaining technical and societal challenges. Georgia Tech researchers in computer science, engineering, psychology and the liberal arts are collaborating under the umbrella of the new Robotics and Intelligent Machines Center that Christensen directs. That cooperation is vital to creating the best-designed personal robots.\u003C\/p\u003E\u003Cp\u003E\u201cIf you just have computer scientists designing robots, you\u2019re not going to build a robot that\u2019s as good as one that could be built by computer scientists and mechanical engineers working together,\u201d Christensen says. \u201cWe are leveraging Georgia Tech\u2019s world-class expertise in all of these domains and want to make something that no one else in the United States is doing today.\u201d\u003C\/p\u003E\u003Cp\u003EThe center\u2019s research agenda draws upon Georgia Tech\u2019s long tradition of robotics study, as well as findings from an ongoing analysis of 40 Georgia companies. Christensen and Professor Steven Danyluk, who heads Georgia Tech\u2019s Manufacturing Research Center, are identifying the problems preventing companies from integrating robots into their operations.\u003C\/p\u003E\u003Cp\u003ESolving industry and workplace problems \u2014 such as robotic robustness and perception \u2014 will lead to better robots in the home and school, researchers say.\u003C\/p\u003E\u003Cp\u003E\u201cIn our lifetimes, we will have a Rosie (of \u2018Jetsons\u2019 fame), the ultimate home assistant,\u201dChristensen says.\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003ETechnical Challenges\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003EBefore personal robots become part of daily life, improvements are needed in personal robot software, robustness, materials, component integration, power and human-machine interaction, researchers say.\u003C\/p\u003E\u003Cp\u003E\u201cTwo key chunks of missing technology are perception and reliability, and research is focusing deeply on these issues,\u201d Balch says.\u003C\/p\u003E\u003Cp\u003EPerception involves the processing of information from a robot\u2019s sensors so the robot understands the outside world \u2014 at least enough to know what it should be doing.\u003C\/p\u003E\u003Cp\u003E\u201cRobots need to be able to interpret their world,\u201d Christensen explains. \u201cIf they go in a new environment, they need to be able to recognize, for example, a chair even though it\u2019s a different chair from one they\u2019ve seen before.\u201d\u003C\/p\u003E\u003Cp\u003EFrom a reliability standpoint, the robot needs to be able to realize when it\u2019s stuck and call for help. \u201cEven better would be that it not get stuck or that it can get itself unstuck,\u201d Balch says.\u003C\/p\u003E\u003Cp\u003EPersonal robots must be robust, able to function 24 hours a day, 7 days a week in a variety of environments. Their industrial counterparts already are being asked to work in an array of environments, including temperature extremes ranging from freezing to 100 degrees or more. Emerging industrial application areas, including poultry processing, require units to work 16 hours a day and also endure a daily cleanup process that employs high-pressure\u003Cbr \/\u003Ewater and caustic chemicals.\u003C\/p\u003E\u003Cp\u003E\u201cDesigning a robot to survive in this environment is difficult,\u201d says Gary McMurray, a senior research engineer in the Georgia Tech Research Institute (GTRI). \u201cYou have to protect the electronics and sensors, so material selection is important. We\u2019ll have to move away from lubricant use for robot joints, and we\u2019ll need the right types of motors and drive systems.\u201d\u003C\/p\u003E\u003Cp\u003EMaterials used to build robots must not only protect components, but also protect the humans that interact with the machines. That requires the development of flexible materials, Christensen says.\u003C\/p\u003E\u003Cp\u003EFor example, robotic arms need to be as flexible as the human arm, which won\u2019t break easily, yet as stiff as the human arm when it lifts and pushes, he explains. An example is a lightweight robot that naturally yields when pushed upon; it is based upon Georgia Tech research and manufactured by the Atlanta company CAMotion Inc.\u003C\/p\u003E\u003Cp\u003EAnother technical challenge is the integration of various products into one robotic system. Microsoft is attempting to address this problem with its new Robotics Studio operating system, though it will face competition from other companies vying to create the robotics operating system of choice, Christensen says.\u003C\/p\u003E\u003Cp\u003EBalch predicts that a standard operating system will accelerate robotics development like IBM\u2019s PC did in the early 1980s. \u201cMicrosoft is now helping define a standard that\u2019s not been there, and I think that companies waiting to enter the robotics marketplace now will enter it,\u201d Balch says. \u201cCombined with the hardware that\u2019s available, this will be the last domino to fall.\u201d\u003C\/p\u003E\u003Cp\u003EIf component integration is the final piece of the puzzle, issues of robot power and human interaction must be addressed first. Better batteries might allow robots to operate untethered for long periods of time, says robotics expert Wayne Book, a Georgia Tech professor of mechanical engineering.\u003C\/p\u003E\u003Cp\u003EBut current batteries are way below the necessary levels of operation. Alternatives are being studied in the Center for Compact and Efficient Fluid Power funded by the National Science Foundation. In building a robot called the Compact Rescue Crawler, Book and his colleagues at Vanderbilt University are addressing the power issue by using energy generated by chemical fluids called monopropellants, such as hydrogen peroxide.\u003C\/p\u003E\u003Cp\u003EIn human-robot interaction, hurdles remain in ease-of-use and communication. Balch likens the goal for personal robot ease-of-use to the simplicity of the TiVo digital video recorder interface. \u201cIt is a technology that you can give to a 70-year-old and not have to worry about helping her with it,\u201d Balch says.\u003C\/p\u003E\u003Cp\u003EFor humans to effectively communicate with personal robots, the machines need to be able to understand spoken language and gestures, Christensen says. For now, those capabilities are limited.\u003C\/p\u003E\u003Cp\u003E\u201cThe big question is, \u2018How can people tell a robot what they want it to do?\u2019\u201d Balch says. \u201cPeople need to be able to show their robot how to do something. Researchers have lots of ideas on how to do this, but the problem is not solved yet.\u201d\u003C\/p\u003E\u003Cp\u003EOne researcher in GTRI is seeking insight by focusing on opportunistic human-robotic interactions that will enable people to work with robots, rather than commanding them.\u003C\/p\u003E\u003Cp\u003EResearcher Lora Weiss is analyzing both social and mathematical networks to understand the dynamics of robot-to-robot and robot-to-human interactions. She is studying these relationships via software and assessing the larger network of dynamic interaction. Her goal is to mathematically capture how humans behave toward machines from a systems perspective.\u003C\/p\u003E\u003Cp\u003E\u201cWithin software, you can provide some intelligent automation to the bots, and then have a system of real people interacting with the machines,\u201d Weiss says. \u201cThe software approach allows one to rapidly populate scenarios with disparate entities and evaluate the emerging and evolving behaviors of the larger system.\u201d\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003ESocial Acceptance\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003ERobots running amok has often been a theme of science fiction. \u201cOne of our biggest enemies is Hollywood,\u201d Christensen says. \u201cThe view of robots that Hollywood projects is almost always negative.\u201d\u003C\/p\u003E\u003Cp\u003EChristensen believes the public\u2019s concern about robots running amok is unrealistic because technology developers place so much emphasis on safety.\u003C\/p\u003E\u003Cp\u003E\u201cWe have to overcome misconceptions about robots,\u201d Christensen says. \u201cWe cannot afford one failure\u2026.We need to make robots that are cute and fun and interact socially with people, but actually help them in their everyday lives.\u201d\u003C\/p\u003E\u003Cp\u003EIn the workplace, for example, Book says convincing people that a lightweight robot can work safely hand in hand with humans, while also being durable and effective, is a more significant challenge than the technical issues.\u003C\/p\u003E\u003Cp\u003E\u201cOnce we can overcome the perception that lightweight robots are flimsy, then every industry will be happy to save money by using these robots,\u201d Book says. \u201cWhen industry starts to accept that lightweight robots can do the job, the perception problem will become a non-issue.\u201d\u003C\/p\u003E\u003Cp\u003ETo build robots that people will accept and even like, researchers draw upon studies in psychology and human-computer interaction.\u003C\/p\u003E\u003Cp\u003E\u201cThere is a general hypothesis that robots similar in appearance to what is familiar to us will ease acceptance,\u201d Balch notes. \u201cIf you see a robot that looks and acts like a puppy, you\u2019re going to treat it as somewhat of a subordinate, but gently. You will guide it.\u201d\u003C\/p\u003E\u003Cp\u003EOn the other end of the spectrum, there are human-looking robots. \u201cYou then expect it can do things like a person, and you\u2019re less patient with it,\u201d Balch says.\u003C\/p\u003E\u003Cp\u003EThat raises the question of whether robots should look like humans. \u201cThe more a robot looks like a person \u2014 it\u2019s called the uncanny valley theory \u2014 the creepier it seems to humans,\u201d Balch explains. \u201cIf you could design a robot that truly looks like a person, people might accept it, but if it\u2019s off target, it\u2019s creepy.\u201d\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003EWhat the Future Holds\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003EChallenges remain for researchers and society in assimilating personal robots into everyday life.\u003C\/p\u003E\u003Cp\u003EOpportunities exist for business, industry, schools and our lives at home. Also, questions of ethics arise, and people are likely to wrestle with these issues.\u003C\/p\u003E\u003Cp\u003EFor business and industry, robots are another technology that helps countries compete in the global marketplace, says Craig Wyvill, chief of GTRI\u2019s Food Processing Technology Division. \u201cWhile industrial robotic technology continues to evolve, it is already demonstrating it can increase product quality and help companies establish themselves as leaders in their fields,\u201d he explains. \u201cIn the process, the workforce must change to support the technology. These changes are essential to staying competitive.\u201d\u003C\/p\u003E\u003Cp\u003EIn schools, personal robots are expected to capture the attention of a new generation of computer scientists and engineers by \u201cembedding learning in an interesting physical thing that moves around,\u201d Balch says.\u003C\/p\u003E\u003Cp\u003EHome may become an easier and more pleasant place to live with personal robots that \u201ctake away the boring parts of life,\u201d Christensen says.\u003C\/p\u003E\u003Cp\u003EAs robots become more commonplace in people\u2019s lives, society must address the ethical questions.\u003C\/p\u003E\u003Cp\u003E\u201cResearchers must involve many others \u2014 such as philosophers and priests \u2014 to contribute to the understanding of the relationship between humans and machines,\u201d Christensen says. \u201cIf we just address these issues as computer scientists and engineers, we may come up with robots that look like what Hollywood creates.\u201d\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Robots are not novel technology in industry, the military and even space exploration.

Others, such as Carnegie Mellon University robotics researcher Hans Moravec, forecast, somewhat gleefully, the day when robots will replace humanity and will serve as our natural successors. Indeed in his vision we, as humans, may become them.\u003C\/p\u003E\u003Cp\u003ERecently, I have engaged in considerable introspection, largely due to my long-term involvement in robotics research. As a scientist I have explored many different domains, all of which impinge on ethical concerns, and I will share a few here.\u003C\/p\u003E\u003Cp\u003ERobots in warfare are becoming the standard for the United States military of the future. A congressional mandate requires that by 2010, one-third of all operational deep-strike aircraft be unmanned and by 2015, one-third of all ground combat vehicles be unmanned.\u003C\/p\u003E\u003Cp\u003EWhile reducing the number of our soldiers on the battlefield seems at first an easy decision, there are many questions related to the viability of this approach. One concerns the issue of lethality, i.e., will intelligent robots be allowed to make decisions regarding the application of lethal force against humans in war without requiring direct human intervention (can a robot pull the trigger on its own)? Can robotic soldiers ultimately be more humane (humane-oids?) than actual warfighters by incorporating a means for ensuring that the laws of war are strictly followed? Our laboratory is currently exploring these questions for the Army, while concurrently designing complex, multi-robot mission software for the Navy.\u003C\/p\u003E\u003Cp\u003EOn the entertainment front, I have been involved with the development of entertainment robots for almost a decade with Sony Corporation\u2019s AIBO (dog) and QRIO (humanoid) robots. The seemingly benign goal here is to create robots that bring joy and happiness into people\u2019s lives, especially among the elderly, and that can serve as life-long partners, not unlike pets or companions.\u003C\/p\u003E\u003Cp\u003EThe real question from an ethical perspective involves the incorporation of human psychological models to tap deeply into an emotional vein unbeknownst to the observer. This in many ways is in common with advertising, cinema, video gaming and other forms of entertainment. The physical embodiment of these robots, however, adds a special dimension that has caused concern among some ethicists and philosophers, particularly in terms of our society abrogating its responsibility for maintaining and enriching human-human contact with the aging. The use of such robots, according to this view, essentially provides an artifact displaying an illusion of life, thus encouraging a further loss of contact with reality by the elderly.\u003C\/p\u003E\u003Cp\u003ERelated to this is the notion of human-robot intimacy and sexuality. The VCR and the Internet have been propelled by pornography to the ubiquity they possess today. It will not be a surprise to see the robotics field also move rapidly in this direction, which it already has in limited ways. We as a society might do well to consider where this might lead: the impact of sex industries built up around this new technology (not simply advanced sexual toys); the consequences of robotic sex therapy perhaps targeted for the rehabilitation or management of sex offenders; robot prostitution; and ultimately, the choices regarding human-robot intimacy on a more permanent basis. As I\u2019ve said in the past, would you want your daughter to marry a robot?\u003C\/p\u003E\u003Cp\u003EA more traditional ethical question for robotics is its impact on unemployment. What would happen if instead of concentrating on the traditional robotic tasks of the 3 Ds (dull, dirty and dangerous), we moved into more mundane environments, such as babysitting, housecleaning and other service industries? What are our responsibilities to displaced workers as a society? Are there lessons from the previous revolutions (industrial and computer) that we can apply here? In the extreme, what if the cost of labor drops to near zero? Will we have a utopian environment of leisure and wealth for all people? Or instead a dystopian future, including humanity\u2019s return to a slavery mindset (albeit robotic), governmental instabilities due to the outsourcing of all work for our species, and a complete dependency on robotic technology where people can no longer function without these machines at all?\u003C\/p\u003E\u003Cp\u003EIf you find some of these issues unsettling, you are not alone. Hence there is now a strong push within the roboethics community, which originated from a series of workshops involving scientists from the robotics community, as well as representatives from the Vatican, the Pugwash Institute and the Geneva Convention, among others, to engage in this debate.\u003C\/p\u003E\u003Cp\u003ESome evidence of progress is the release of the recent EURON Roboethics Roadmap (\u003Ca href=\u0022http:\/\/www.roboethics.org\/\u0022\u003Ewww.roboethics.org\u003C\/a\u003E).

The tailored organic phosphonic acid ligands, designed and synthesized by a research group headed by Seth Marder - a professor in the Georgia Tech School of Chemistry and Biochemistry - provide a robust coating for the particles, which range in size from 30 to 120 nanometers in diameter. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Phosphonic acids bind very well to barium titanate and to other related metal oxides,\u0022 Perry said.  \u0022The choice of that material and ligands were very effective in allowing us to take the tailored phosphonic acids, put them onto the barium titanate, and then with the correct solution processing, to incorporate them into polymer systems. This allowed us to provide good compatibility with the polymer hosts - and thus very good dispersion as evidenced by a three- to four-fold decrease in the average aggregate size.\u0022 \n\u003C\/p\u003E\n\u003Cp\u003EThough large crystals of barium titanate could also provide a high dielectric constant, they generally do not provide adequate resistance to breakdown - and their formation and growth can be complex and require high temperatures.  Composites provide the necessary electrical properties, along with the advantages of solution-based processing techniques.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022One of the big benefits of using a polymer nanocomposite approach is that you combine particles of a material that provide desired properties in a matrix that has the benefits of easy processing,\u0022 Perry explained.\n\u003C\/p\u003E\n\u003Cp\u003EThough the new materials may already offer enough of an advantage to justify commercializing, Perry believes there are additional opportunities for boosting their performance.  The research team also wants to scale up production to make larger samples - now produced in two-inch by three-inch films - available to other researchers who may wish to develop additional applications.\n\u003C\/p\u003E\n\u003Cp\u003EPerry and Marder are working with Bernard Kippelen, a professor in the Georgia Tech School of Electrical and Computer Engineering, on the use of these new nanocomposites in organic thin-film transistors in which solution-based techniques are used to fabricate inexpensive electronic components.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Beyond capacitors, there are many areas where high dielectric materials are important, such as field-effect transistors, displays and other electronic devices,\u0022 Perry added.  \u0022With our material, we can provide a high dielectric layer that can be incorporated into those types of applications.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn addition to those already mentioned, the research team included Philseok Kim, Simon Jones, Peter Hotchkiss and Joshua Haddock.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\nGeorgia Institute of Technology\u003Cbr \/\u003E\n75 Fifth Street, N.W., Suite 100\u003Cbr \/\u003E\nAtlanta, Georgia  30308  USA\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contact\u003C\/strong\u003E: John Toon (404-894-6986); E-mail: (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ETechnical Contact\u003C\/strong\u003E: Joe Perry (404-385-6046); E-mail: (\u003Ca href=\u0022mailto:joe.perry@gatech.edu\u0022\u003Ejoe.perry@gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: John Toon\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Nanoparticle technique could double energy storage for defense and consumer uses"}],"field_summary":[{"value":"A new technique for creating films of barium titanate (BaTiO3) nanoparticles in a polymer matrix could allow fabrication of improved capacitors able to store twice as much energy as conventional devices.","format":"limited_html"}],"field_summary_sentence":[{"value":"Improved nanoparticles could boost capacitors"}],"uid":"27303","created_gmt":"2007-04-26 00:00:00","changed_gmt":"2016-10-08 03:03:29","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2007-04-26T00:00:00-04:00","iso_date":"2007-04-26T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"72199":{"id":"72199","type":"image","title":"Researchers with capacitor array","body":null,"created":"1449177446","gmt_created":"2015-12-03 21:17:26","changed":"1475894651","gmt_changed":"2016-10-08 02:44:11"},"72200":{"id":"72200","type":"image","title":"Capacitor research team","body":null,"created":"1449177446","gmt_created":"2015-12-03 21:17:26","changed":"1475894651","gmt_changed":"2016-10-08 02:44:11"},"72201":{"id":"72201","type":"image","title":"Comparison of materials","body":null,"created":"1449177446","gmt_created":"2015-12-03 21:17:26","changed":"1475894651","gmt_changed":"2016-10-08 02:44:11"}},"media_ids":["72199","72200","72201"],"related_links":[{"url":"http:\/\/www.chemistry.gatech.edu\/","title":"School of Chemistry and Biochemistry"},{"url":"http:\/\/www.cope.gatech.edu\/","title":"COPE"},{"url":"http:\/\/www.chemistry.gatech.edu\/faculty\/Perry\/","title":"Joseph Perry\\\u0027s home page"}],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"141","name":"Chemistry and Chemical Engineering"},{"id":"147","name":"Military Technology"},{"id":"135","name":"Research"}],"keywords":[{"id":"7564","name":"capacitor"},{"id":"7563","name":"nanocomposite"},{"id":"2054","name":"nanoparticle"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003Cbr \/\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=jt7\u0022\u003EContact John Toon\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6986\u003C\/strong\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}},"72371":{"#nid":"72371","#data":{"type":"news","title":"Automated System Installs Pavement Markers","body":[{"value":"\u003Cp\u003EOn rainy nights in Georgia and across the nation, drivers greatly benefit from small, reflective markers that make roadway lanes more visible. A new automated system for installing the markers is expected to improve safety for workers and drivers.\u003C\/p\u003E\n\u003Cp\u003EThere are more than three million of these safety devices, called raised pavement markers (RPMs), in service on Georgia highways. They are installed and then need to be replaced about every two years by road crews who consider the task one of the riskiest they face. Workers typically ride on a seat cantilevered off the side of a trailer just inches from highway traffic.\n\u003C\/p\u003E\n\u003Cp\u003EManual RPM placement is not only risky for personnel, but it is also expensive and time-consuming. A typical RPM placement operation includes four vehicles and a six-person crew. All the vehicles must stop at each marker location, so there is tremendous wear on the equipment and increased fuel use.\n\u003C\/p\u003E\n\u003Cp\u003EThe Georgia Department of Transportation (GDOT) believed there was a better way to do it and funded the Georgia Tech Research Institute (GTRI) to develop a first-of-its-kind system capable of automatically placing RPMs along the lane stripes while in motion. After almost three years of research and development, GTRI expects to deliver a prototype system early this year. Because of widespread interest in the system, researchers will present a report on their project on Jan. 23 at the National Research Council\u0027s Transportation Research Board Annual Meeting in Washington, D.C.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The advantages of our automated system are:  it\u0027s less labor-intensive, it\u0027s faster and safer, uses less fuel, and it causes less wear and tear on GDOT equipment,\u0022 explained project manager Wiley Holcombe, a GTRI senior research engineer.\n\u003C\/p\u003E\n\u003Cp\u003EEngineers conducted the work in two phases. First, they designed an RPM-placement mechanism using pressure-sensitive adhesive and a lane-stripe tracking system. Then, they developed a full-scale, truck-mounted RPM placement system. It is based on a single GDOT-owned truck and includes the lane-stripe tracking system, and electrical power, compressed air, hydraulic power, and adhesive melting and dispensing systems. Some components of the system were off-the-shelf parts, but the GTRI Machine Services shop fabricated most of the custom components for the system, Holcombe notes.\n\u003C\/p\u003E\n\u003Cp\u003EAfter some field-testing, the project resulted in a prototype system capable of dispensing an RPM onto the pavement along with the necessary hot-melt adhesive applied at 380 degrees Fahrenheit while traveling at 5 miles an hour. A pattern-change mechanism can position two placement mechanisms to accommodate any of GDOT\u0027s five specified RPM placement patterns, Holcombe explains.\n\u003C\/p\u003E\n\u003Cp\u003EOperation of the system only requires two people. An operator on the back of the truck loads the adhesive melters with adhesive and stacks RPMs in the hoppers from which they are dispensed, depending on the placement pattern. Meanwhile, the driver of the truck must maintain alignment between the stripe pattern on the road and a caster wheel on a boom in front of the truck. Also, the driver touches a computer screen in the cab to indicate to the placement system the new stripe pattern each time the caster wheel crosses a stripe pattern change.\n\u003C\/p\u003E\n\u003Cp\u003ERPMs are dispensed from the hoppers onto a loader arm, which deposits them onto a telescoping slide that connects to a placement mechanism on an attached carriage. The carriage has a 3-foot range of travel and is moved laterally to keep the placement mechanism centered along the road stripe. RPMs are then typically applied about 80 feet apart. It takes about 35 milliseconds from the time the edge of the RPM hits the ground to the time it\u0027s flush with the road, Holcombe notes.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The GDOT\u0027s primary use for the automated RPM placement machine will be placing markers on the skip lines for interstate and multi-lane highways,\u0022 said GDOT spokeswoman Karlene Barron. \u0022These types of routes pose the highest safety risks to our employees and equipment.\u0022  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022The GDOT also plans to use the system on high-traffic-volume secondary or two-lane roads, when possible,\u0022 Barron added. \u0022Using the automated system, we will not have to stop at every placement, which will increase safety and productivity plus reduce wear and tear on GDOT equipment. Plus the operator will be high on the back of the machine instead of near ground level.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ESix of GDOT\u0027s seven district offices have their own RPM placement crews, and there are four other crews that work statewide.

The converted shells, which retain the 3-D shape and nanoscale detail of the originals, could also be useful as battery electrodes, chemical purifiers - and in other applications requiring complex shapes that nature can produce better than humans.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022When we conducted measurements for the detection of nitric oxide, a common pollutant, our single diatom-derived silicon sensor possessed a combination of speed, sensitivity, and low voltage operation that exceeded conventional sensors,\u0022 said Kenneth H. Sandhage, a professor in the School of Materials Science and Engineering at the Georgia Institute of Technology.  \u0022The unique diatom-derived shape, high surface area and nanoporous, nanocrystalline silicon material all contributed towards such attractive gas sensing characteristics.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe unique devices, part of a broader long-term research program by Sandhage and his research team, were described in the March 8 issue of the journal \u003Cem\u003ENature\u003C\/em\u003E.  The research was sponsored by the U.S. Air Force Office of Scientific Research and the U.S. Office of Naval Research. \n\u003C\/p\u003E\n\u003Cp\u003EScientists estimate that roughly 100,000 species of diatoms exist in nature, and each forms a microshell with a unique and often complex 3-D shape that includes cylinders, wheels, fans, donuts, circles and stars.  Sandhage and his research team have worked for several years to take advantage of those complex shapes by converting the original silica into materials that are more useful.\n\u003C\/p\u003E\n\u003Cp\u003EUltimately, they would like to conduct such conversion reactions on genetically-modified diatoms that generate microshells with tailored shapes. However, to precisely alter and control the structures produced, further research is needed to learn how to manipulate the genome of the diatom. Since scientists already know how to culture diatoms in large volumes, harnessing the diatom genetic code could allow mass-production of complex and tailored microscopic structures. \n\u003C\/p\u003E\n\u003Cp\u003ESandhage\u0027s colleagues, Prof. Nils Kr\u00c3\u00b6ger (School of Chemistry and Biochemistry at Georgia Tech) and Dr. Mark Hildebrand (Scripps Institution of Oceanography) are currently conducting research that could ultimately allow for genetic engineering of diatom microshell shapes.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Diatoms are fabulous for making very precise shapes, and making the same shape over and over again by a reproduction process that, under the proper growth conditions, yields microshells at a geometrically-increasing rate,\u0022 Sandhage noted.  \u0022Diatoms can produce three-dimensional structures that are not easy to produce using conventional silicon-based processes.  The potential here is for making enormous numbers of complicated 3-D shapes and tailoring the shapes genetically, followed by chemical modification as we have conducted to convert the shells into functional materials such as silicon.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ESilicon is normally produced from silica at temperatures well above the silicon melting point (1,414 degrees Celsius), so that solid silicon replicas cannot be directly produced from silica structures with such conventional processing.  So the Georgia Tech researchers used a reaction based on magnesium gas that converted the silica of the shells into a composite containing silicon (Si) and magnesium oxide (MgO).  The conversion took place at only 650 degrees Celsius, which allowed preservation of the complex channels and hollow cylindrical shape of the diatom. \n\u003C\/p\u003E\n\u003Cp\u003EThe magnesium oxide, which makes up about two-thirds of the composite, was then dissolved out by a hydrochloric acid solution, which left a highly porous silicon structure that retained the original shape.  The structure was then treated with hydrofluoric acid (HF) to remove traces of silica created by reaction with the water in the hydrochloric acid solution.\n\u003C\/p\u003E\n\u003Cp\u003EThe researchers then connected individual diatom-derived silicon structures to electrodes, applied current and used them to detect nitric oxide.  The highly porous silicon shells, which are about 10 micrometers in length, could also be used to immobilize enzymes for purifying drugs in high-performance liquid chromatography (HPLC) and as improved electrodes in lithium-ion batteries.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Silicon can form compounds that have a high lithium content,\u0022 Sandhage said.  \u0022Because diatom-derived silicon structures have a high surface area and are thin walled and highly porous, the rate at which you can get lithium ions into and out of such silicon structures can be high.  For a given battery size, you could store more power, use it more rapidly or recharge the battery faster by using such structures as electrodes.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn testing, the researchers showed that the silicon they produced was photoluminescent - meaning it glows when illuminated by certain wavelengths of light.  That shows the fabrication process produced a nanoporous, nanocrystalline structure - and may have interesting photonic applications in addition to the electronic ones.\n\u003C\/p\u003E\n\u003Cp\u003EThough Sandhage and his collaborators have demonstrated the potential of their technique, significant challenges must be overcome before they can produce useful sensors, battery electrodes and other structures.  The sensors will have to be packaged into useful devices, for example, connected into arrays of devices able to detect different gases and scaled up for volume manufacture.\n\u003C\/p\u003E\n\u003Cp\u003EThe \u003Cem\u003EAulacoseira\u003C\/em\u003E diatoms used in the research reported by \u003Cem\u003ENature\u003C\/em\u003E were millions of years old, obtained from samples mined and distributed as diatomaceous earth.

That\u0027s also true for other Southern states - and in other technologies, notes Philip Shapira, another co-author and a professor in Georgia Tech\u0027s School of Public Policy.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022We have growing research capabilities, but the real issue is whether we have the commercialization capabilities,\u0022 he noted.\n\u003C\/p\u003E\n\u003Cp\u003EThough Georgia has invested in developing startup companies, it\u0027s not yet clear what role early-stage companies will play in turning nanotechnology innovations into commercial products. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Nanotechnology is very pervasive across industry because it facilitates improvement in a broad range of products and processes,\u0022 Shapira said.  \u0022For example, we are seeing nanoparticles and nanofibers being introduced as parts of tires, microelectronics, clothing and biomedicine.  These industries are dominated by big companies, so this may be an area where big companies have a more important role to play than startups.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EBecause the nanotechnology industry is young and will likely advance through several distinct growth phases, state efforts to gain leadership still have time to pay off, Shapira says.  To take advantage of the nanotechnology revolution, he adds, Georgia will not only have to attract more venture capital for startups, but also develop linkages with well-funded companies that have the resources to bring new products to market.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022None of these are easy or automatic, but they are areas that we have to push,\u0022 he said.  \u0022I think there is a window during which Georgia could emerge as a bigger player in nanotechnology commercialization if we can develop strategic policy action, as well as leadership on the business side.\u0022\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003E\u003Cem\u003EThis article appears in the Fall 2006 issue of Research Horizons, the Georgia Tech Research Magazine.\u003C\/em\u003E\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp;

Commercially available platinum nanocrystals - which exist as cubes, tetrahedra and octahedra - have what are termed \u0022low-index\u0022 facets, characterized by the numbers {100} or {111}.  Because of their higher catalytic activity, \u0022high-index\u0022 surfaces would be preferable - but until now, platinum nanocrystals with such surfaces have never been synthesized - and therefore have not been available for industrial use.\n\u003C\/p\u003E\n\u003Cp\u003EThe nanocrystals produced by the U.S.-Chinese team have high energy surfaces that include numerous \u0022dangling bonds\u0022 and \u0022atomic steps\u0022 that facilitate chemical reactions.  These structures, characterized by {210}, {730} or {520} facets, remain stable at high temperatures - up to 800 degrees Celsius in testing done so far.  That stability will allow them to be recycled and re-used in catalytic reactions, Wang said.\n\u003C\/p\u003E\n\u003Cp\u003EThough the process must still be fine-tuned, the researchers have learned to control the size of the particles by varying the processing conditions.

Placed in an electrochemical cell with ascorbic acid and sulfuric acid, the spheres are then subjected to \u0022square wave\u0022 potential that alternates between positive and negative potentials at a rate of 10 to 20 Hertz.  \n\u003C\/p\u003E\n\u003Cp\u003EThe electrochemical oxidation-reduction reaction converts the spheres to smaller nanocrystals over a period of time ranging from 10 to 60 minutes.

In microcosm studies in her lab, Bedard found that Aroclor 1260 was indeed being degraded by native sediment microbes, and she developed sediment-free enrichment cultures. \u003C\/p\u003E\n\u003Cp\u003EShe then worked with Georgia Tech researchers Frank Loeffler and Kirsti Ritalahti to further characterize these Aroclor 1260-dechlorinating enrichment cultures. Through a series of experiments, the team was able to determine that bacteria in the Dehalococcoides (Dhc) group were responsible for the dechlorination of Aroclor 1260. These microbes replace the chlorine atoms in Aroclor 1260 with hydrogen, which fuels their growth and initiates the PCB degradation process, explained Loeffler, an associate professor in the School of Civil and Environmental Engineering and the School of Biology.\n\u003C\/p\u003E\n\u003Cp\u003EThe research indicates that the Dhc bacteria active in the enrichment cultures also contribute to PCB dechlorination in situ (i.e., in the Housatonic River sediment). Once Dhc bacteria dechlorinate Aroclor 1260 to a certain level, other microbial species will degrade it further and completely detoxify PCBs, Loeffler added.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Identifying the bacteria responsible for Aroclor degradation represents a crucial step. Now we can start to design tools to look for these microbes in sediments and then develop engineering approaches to stimulate their growth and activity in river or lake sediments,\u0022 Loeffler said. \u0022Then the decontamination will occur more rapidly. Instead of taking decades, the microbes might be able to degrade the PCBs in a few years.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ELoeffler is optimistic about a bioremediation strategy for PCBs because of his lab\u0027s earlier success in identifying microbes that degrade the common solvents tetrachloroethene (PCE) and trichloroethene (TCE). These toxic compounds, which contaminated subsurface environments and groundwater decades ago when their use was unregulated, are primarily used in dry cleaning operations and degreasing of metal components. Following Loeffler\u0027s discovery, it took less than five years for scientists and engineers to develop and implement bioremediation strategies that use these microbes to detoxify PCE and TCE.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The situation with PCBs is a little more complicated because they are in river and lake sediments instead of groundwater and subsurface environments, but in principle, the same sequence of events could occur,\u0022 Loeffler said. \u0022We need industry, engineers and scientists to work together to develop a bioremediation approach for PCBs.\u0022 \n\u003C\/p\u003E\n\u003Cp\u003ELoeffler predicts that bioremediation technologies for addressing PCB detoxification will be developed first for lakes, such as PCB-contaminated portions of Lake Hartwell in South Carolina. Then it will be refined to clean up river sediments, where the flow rate is greater and bioremediation may be more difficult to implement, he added.\n\u003C\/p\u003E\n\u003Cp\u003EDevelopment of bioremediation technologies for PCB cleanup would offer an alternative to sediment dredging and disposal in landfills, which is the most commonly used method for removing PCBs. Dredging is controversial because of the invasive nature of this technology and the risk of spreading contaminants.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Now, because of our research, regulators know these microbes exist, that they are native to certain environments and that natural degradation processes are at work,\u0022 Loeffler said. \u0022Maybe this will influence decision-making processes, and bioremediation will be implemented. This could save millions of dollars spent on controversial dredging projects.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn the meantime, Loeffler and his colleagues continue to characterize Dhc bacteria.

This directional component is an important improvement over the current technology, researchers said. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Detecting quiet sounds under water can be very difficult,\u0022 said Francois Guillot, a research engineer in Georgia Tech\u0027s George W.

Inside a fish\u0027s ear, there are thousands of tiny hairs that move when a sound wave passes through the fish. These hairs then communicate with nerves allowing fish to hear under water. Because fish excel at detecting sound so they don\u0027t get eaten, the Georgia Tech researchers chose the fish hearing system as their model, they said.\n\u003C\/p\u003E\n\u003Cp\u003EGuillot described the novel underwater sensor late last fall at the 4th joint meeting of the Acoustical Society of America and the Acoustical Society of Japan in Honolulu, Hawaii. His presentation was part of a session titled \u0022Underwater Acoustics: Array Processing, Sensors, and Technology.\u0022\u003C\/p\u003E\n\u003Cp\u003EIn the field of underwater acoustics, there is always a need to develop more sophisticated sensors, researchers said. The Navy currently tows long lines of hydrophones to listen to sound under water -- much like a microphone listens to sound in the air. A hydrophone measures the pressure change associated with the propagation of a sound wave. It converts acoustic energy into electrical energy and is used in passive underwater systems to listen only. One hydrophone identifies  a sound nearby, and multiple hydrophones can help tell the direction from which it\u0027s coming. But directional ambiguity exists. A line array of hydrophones cannot tell if the sound is coming from the left or right.\n\u003C\/p\u003E\n\u003Cp\u003EGuillot and collaborators David Trivett, a principal research scientist, and Peter Rogers, a professor -- both in the School of Mechanical Engineering -- have developed a more compact, more sensitive sound detector that can provide unambiguous directional information. In addition, the sensor can be modified to measure the water deformation, known as shear, associated with a sound wave --  a quantity typically difficult to measure because it requires very sensitive instruments. This new sensor shows promise that it can be successfully modified to detect this acoustic shear, which will enhance the directional information, the researchers said.\n\u003C\/p\u003E\n\u003Cp\u003EThe sensor is designed with two small plates attached by a hinge. One plate is held rigidly, and the other plate -- made of a composite material with the same density as water -- is free to move. The freely moving plate shifts in the sound field and follows the motion of water. A light signal sent through an optical fiber glued to both plates is modified by the motion of the freely moving plate. Analyzing the light signal with a photodetector provides information relative to the sound waves.\n\u003C\/p\u003E\n\u003Cp\u003EThe sensor developed at Georgia Tech offers advantages over existing systems, researchers said. Guillot hopes the new sensor changes the way the Navy detects sound under water.\u003Cbr \/\u003E\n\u0022If the Navy tows an array of hydrophones thousands of feet long, it makes it difficult to maneuver the ship,\u0022 Rogers said. \u0022Since we can cut that length by a factor of more than five, it will cost less money to operate and be easier to handle.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe current prototype sensor has been tested in the School of Mechanical Engineering\u0027s large underwater acoustic tank facility to observe the behavior of the sensor under water.

In the analog domain, chips and other devices work by moving between signal levels in a continuous fashion, while digital chips and devices move between separate and discontinuous levels and do not recognize the transition between levels. \n\u003C\/p\u003E\n\u003Cp\u003EMicromechanical circuits have a number of advantages over electronic digital chips.

These devices play a role in finding and holding a radio-frequency signal.\n\u003C\/p\u003E\n\u003Cp\u003EIn constructing extensive arrays of signal-seeking BAW resonators, researchers must choose between two approaches.  One is to use resonators to create an array of many fixed filters -- each tuned to a specific frequency -- that will cover the entire spectrum.  The other approach involves tunable filters that can move back and forth to some degree between frequencies. Ayazi said that further research will determine the optimal approach.\n\u003C\/p\u003E\n\u003Cp\u003EThe structural material of choice for acoustic-wave resonators will be nano-crystalline diamond, micro-machined to reach frequencies of up to 10 GHz. \n\u003C\/p\u003E\n\u003Cp\u003EResearchers will also use silver, the highest-conductivity metal, in micro-machining the analog arrays.

Working at microscale, researchers must create a small cavity on top of the electronics to achieve a hermetic environment that will seal out damaging moisture.\n\u003C\/p\u003E\n\u003Cp\u003EA key to ASP packaging will be advanced organic materials that possess low signal-loss properties and are strong and semi-hermetic.  Working with Prof. Paul Kohl of Georgia Tech\u0027s School of Chemical and Biomolecular Engineering, Ayazi will use specially-tailored polymers to develop an effective package for the filter arrays.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The combination of all these elements will eventually produce an array of highly improved tunable filters,\u0022 Ayazi said. \u0022We are basically looking for orders of magnitude improvement in performance, size and cost.

Our nanogenerator allows us to harvest or recycle energy from many sources to power these devices.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EDetails of the nanogenerator are reported in the April 6 issue of the journal \u003Cem\u003EScience\u003C\/em\u003E.  The research was sponsored by the Defense Advanced Research Projects Agency (DARPA), the National Science Foundation (NSF), and the Emory-Georgia Tech Center of Cancer Nanotechnology Excellence.\n\u003C\/p\u003E\n\u003Cp\u003EThe nanogenerators take advantage of the unique coupled piezoelectric and semiconducting properties of zinc oxide nanostructures, which produce small electrical charges when they are flexed.  \n\u003C\/p\u003E\n\u003Cp\u003EFabrication begins with growing an array of vertically-aligned nanowires approximately a half-micron apart on gallium arsenide, sapphire or a flexible polymer substrate.  A layer of zinc oxide is grown on top of substrate to collect the current.  The researchers also fabricate silicon \u0027zig-zag\u0027 electrodes, which contain thousands of nanometer-scale tips made conductive by a platinum coating.\n\u003C\/p\u003E\n\u003Cp\u003EThe electrode is then lowered on top of the nanowire array, leaving just enough space so that a significant number of the nanowires are free to flex within the gaps created by the tips. Moved by mechanical energy such as waves or vibration, the nanowires periodically contact the tips, transferring their electrical charges.  By capturing the tiny amounts of current produced by hundreds of nanowires kept in motion, the generators produce a direct current output in the nano-Ampere range.  \n\u003C\/p\u003E\n\u003Cp\u003EWang and his group members Xudong Wang, Jinhui Song and Jin Liu expect that with optimization, their nanogenerator could produce as much as 4 watts per cubic centimeter - based on a calculation for a single nanowire.  That would be enough to power a broad range of nanometer-scale defense, environmental and biomedical applications, including biosensors implanted in the body, environmental monitors - and even nanoscale robots.\n\u003C\/p\u003E\n\u003Cp\u003ENearly a year ago, in the April 14, 2006 issue of the journal \u003Cem\u003EScience\u003C\/em\u003E, Wang\u0027s research team announced the concept behind the nanogenerators.  At that time, the nanogenerator could harvest power from just one nanowire at a time by dragging the tip of an atomic force microscope (AFM) over it.  Made of platinum-coated silicon, the tip served as a Schottky barrier, helping accumulate and preserve the electrical charge as the nanowire flexed - and ensuring that the current flowed in one direction.\n\u003C\/p\u003E\n\u003Cp\u003EWith its multiple conducting tips similar to those of an AFM, the new zig-zag electrode serves as a Schottky barrier to hundreds or thousands of wires simultaneously, harvesting energy from the nanowire arrays.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Producing the top electrode as a single assembly sets the stage for scaling up this technology,\u0022 Wang said.  \u0022We can now see the steps involved in moving forward to a device that can power real nanometer-scale applications.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EBefore that happens, additional development will be needed to optimize current production.  For instance, though nanowires in the arrays can be grown to approximately the same length - about one micron - there is some variation.  Wires that are too short cannot touch the electrode to produce current, while wires that are too long cannot flex to produce electrical charge.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We need to be able to better control the growth, density and uniformity of the wires,\u0022 Wang said.  \u0022We believe we can make as many as millions or even billions of nanowires produce current simultaneously.  That will allow us to optimize operation of the nanogenerator.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn their lab, the researchers aimed an ultrasound source at their nanogenerator to measure current output over slightly more than an hour.  Though there is some fluctuation in output, the current flow was continuous as long as the ultrasonic generator was operating, Wang said.\n\u003C\/p\u003E\n\u003Cp\u003ETo rule out other sources of the current measured, the researchers substituted carbon nanotubes - which are not piezoelectric - for the zinc oxide nanowires, and used a top electrode that was flat.  In both cases, the resulting devices did not produce current.\n\u003C\/p\u003E\n\u003Cp\u003EProviding power for nanometer-scale devices has long been a challenge.  Batteries and other traditional sources are too large, and tend to negate the size advantages of nanodevices.

Nie and Sathe synthesize the quantum dots in different colors by varying their size, giving the beads a unique optical signature. Having different color beads allows the researchers to detect several target molecules at the same time in the same liquid sample.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We use the quantum dots to create a set of beads that are unique and can be distinguished from each other. It\u0027s similar to bar-coding -- once you barcode the beads and put them in the urine or blood sample, you can remove them and decode what proteins or viruses have attached to individual beads based on their spectral signature,\u0022 explained Sathe.\n\u003C\/p\u003E\n\u003Cp\u003EThe process of creating these beads is quite simple, according to Sathe. The surface of the beads contains a long-chain carbon molecule that makes the beads hydrophobic, meaning they repel water. The beads are dissolved in butanol and washed several times. Then the beads are counted and optical and magnetic nanocrystals are added to the suspension either simultaneously or sequentially. \n\u003C\/p\u003E\n\u003Cp\u003EAfter 15-20 minutes, the butanol is removed to get rid of any remaining nanoparticles that didn\u0027t get incorporated into the beads and the beads are washed with ethanol. Then the beads are coated with a polymer that creates a hydrophilic surface on the beads. This allows the beads to be functionalized by adding antibodies or DNA molecules to the surface that will capture the target molecules.\n\u003C\/p\u003E\n\u003Cp\u003EThese beads are dual-function -- both optical and magnetic -- but according to Sathe, more functions can be added to the beads. \u0022Adding them is as easy as adding the nanoparticles into the solution.

To boost its survival chances, \u003Cem\u003EPhaeocystis globosa\u003C\/em\u003E will enhance or suppress the formation of colonies based on whether nearby grazers prefer eating large or small particles.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Based on chemical signals from attacked neighbors, \u003Cem\u003EPhaeocystis globosa\u003C\/em\u003E enhances colony formation if that\u0027s the best thing to do for survival, or it suppresses the formation of colonies in favor of growing as small solitary cells if that\u0027s the best thing to do,\u0022 said Mark E. Hay, Teasley Professor of Biology at the Georgia Institute of Technology.  \u0022These changes in form made nearly a 100-fold difference in the alga\u0027s susceptibility to being eaten.  It\u0027s certainly surprising that a single-celled organism can chemically sense the presence of nearby consumers, identify those consumers and change in opposing ways depending on which consumers are present.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe behavior could have implications for global climate change because \u003Cem\u003EPhaeocystis\u003C\/em\u003E blooms play a key role in the carbon cycle of cold oceans, accounting for up to 85 percent of local productivity during some time periods.  This complex defensive behavior also shows how environmental factors can affect even simple organisms, Hay noted.  \n\u003C\/p\u003E\n\u003Cp\u003EConducted largely at Georgia Tech\u0027s marine lab in Savannah, Ga., the research was sponsored by the U.S. National Science Foundation and the U.S. Environmental Protection Agency.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EPhaeocystis\u003C\/em\u003E has two primary predators: small grazers such as ciliates, which prefer to eat small solitary cells that are four to six microns in diameter, and the larger shrimp-like copepods, which prefer to eat large, ball-shaped colonies.\n\u003C\/p\u003E\n\u003Cp\u003EWhen copepods are attacking the phytoplankton, therefore, the best survival strategy of \u003Cem\u003EPhaeocystis\u003C\/em\u003E is to form solitary cells.  When ciliates are attacking, the best strategy is to form colonies that are too large for those predators to consume.\n\u003C\/p\u003E\n\u003Cp\u003ELead author Jeremy D. Long, along with collaborators Gabriella W. Smalley, Todd Barsby, Jon T. Anderson and Mark Hay found that\u0027s just what \u003Cem\u003EPhaeocystis\u003C\/em\u003E does.  Chemicals that signaled attacks from copepods suppressed the formation of colonies by 60 to 90 percent, while signals from ciliates enhanced colony formation by more than 25 percent.\n\u003C\/p\u003E\n\u003Cp\u003EThe transformations took place over periods of three to six days, and the overall size difference could be dramatic.  \u0022When one of these cells changes to the biggest colony form, although it takes a while, it\u0027s like changing from a mosquito to 76 blue whales or 3,000 bull elephants,\u0022 Hay explained.  \u0022That\u0027s a pretty dramatic difference.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EDefensive responses are often seen in higher plants, but this is believed to be the first report of such a complex and species-specific response in marine phytoplankton.  Hay suspects scientists may find other examples of complex defensive strategies when they look more closely at other single-celled organisms.\n\u003C\/p\u003E\n\u003Cp\u003EThe response of \u003Cem\u003EPhaeocystis\u003C\/em\u003E could be important to scientists studying climate change because the predator that ultimately consumes the phytoplankton determines the fate of the carbon it contains.  If eaten by copepods, for example, the carbon becomes part of fecal packages that sink into the deep ocean where a portion of that carbon is sequestered - thereby reducing atmospheric carbon dioxide, a leading greenhouse gas.  If consumed by smaller creatures like ciliates, less of the carbon sinks to the deep sea and more remains in the surface waters.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This could alter the flow of energy and nutrients from deep to shallow, depending on what might be trying to eat it, and how the organism responds to the chemical signals of what\u0027s attacking it,\u0022 Hay said.\n\u003C\/p\u003E\n\u003Cp\u003EExperimentally, the researchers attempted to separate the chemical signals from the actual predators.  They grew \u003Cem\u003EPhaeocystis\u003C\/em\u003E in the presence of either ciliates or copepods.  They then filtered out both the phytoplankton and predators, leaving only water containing the chemical signals of attack.\n\u003C\/p\u003E\n\u003Cp\u003EWater samples containing signals from the two predators were then separately introduced into \u003Cem\u003EPhaeocystis\u003C\/em\u003E cultures that had not been attacked.  The scientists then studied how the different chemical signals affected the percentage of \u003Cem\u003EPhaeocystis\u003C\/em\u003E living in colonies or as solitary cells.  Finally, they examined whether this response affected how much the predators ate to determine if the change conferred a survival advantage.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We found that these organisms were making the right choice,\u0022 Hay said.  \u0022They were shifting to the shape that made them largely immune to whichever predator was attacking, and this shift suppressed either the feeding or growth and reproduction of the consumer to which they were responding.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe role of this phytoplankton has been controversial in the scientific community, with some arguing that \u003Cem\u003EPhaeocystis\u003C\/em\u003E makes a good food source for higher creatures in the cold oceans, while others contend its food role is small.  While this paper won\u0027t resolve the dispute, Hay believes it shows that both points of view could be correct - depending on which form the organism has taken.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022It depends on the environmental context, which we are appreciating more and more in ecology and in biomedical research,\u0022 he added.  \u0022Some of these differences are small, but they can have a large effect.\u0022\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\nGeorgia Institute of Technology\u003Cbr \/\u003E\n75 Fifth Street, N.W., Suite 100\u003Cbr \/\u003E\nAtlanta, Georgia  30308  USA\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contact\u003C\/strong\u003E: John Toon (404-894-6986); E-mail: (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ETechnical Contact\u003C\/strong\u003E: Mark Hay (404-894-8429); E-mail: (\u003Ca href=\u0022mailto:mark.hay@biology.gatech.edu\u0022\u003Emark.hay@biology.gatech.edu\u003C\/a\u003E)\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: John Toon\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Single-celled organisms respond to different predators in different ways"}],"field_summary":[{"value":"A tiny single-celled organism that plays a key role in the carbon cycle of cold-water oceans may be a lot smarter than scientists had suspected.","format":"limited_html"}],"field_summary_sentence":[{"value":"Single-celled algae can display complex behaviors"}],"uid":"27303","created_gmt":"2007-06-15 00:00:00","changed_gmt":"2016-10-08 03:03:29","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2007-06-15T00:00:00-04:00","iso_date":"2007-06-15T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"72039":{"id":"72039","type":"image","title":"Copepod predator","body":null,"created":"1449177425","gmt_created":"2015-12-03 21:17:05","changed":"1475894649","gmt_changed":"2016-10-08 02:44:09"},"72040":{"id":"72040","type":"image","title":"Phaeocystis solitary cells","body":null,"created":"1449177425","gmt_created":"2015-12-03 21:17:05","changed":"1475894649","gmt_changed":"2016-10-08 02:44:09"},"72041":{"id":"72041","type":"image","title":"Phaeocystis colony","body":null,"created":"1449177425","gmt_created":"2015-12-03 21:17:05","changed":"1475894649","gmt_changed":"2016-10-08 02:44:09"}},"media_ids":["72039","72040","72041"],"related_links":[{"url":"http:\/\/www.biology.gatech.edu\/faculty\/mark-hay\/","title":"Mark Hay"},{"url":"http:\/\/www.biology.gatech.edu\/","title":"School of Biology"}],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"154","name":"Environment"},{"id":"146","name":"Life Sciences and Biology"},{"id":"135","name":"Research"}],"keywords":[{"id":"610","name":"carbon"},{"id":"2262","name":"climate"},{"id":"1366","name":"defense"},{"id":"7561","name":"phytoplankton"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003Cbr \/\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=jt7\u0022\u003EContact John Toon\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6986\u003C\/strong\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}},"72223":{"#nid":"72223","#data":{"type":"news","title":"3D Solar Cells Boost Efficiency, Reduce Size","body":[{"value":"\u003Cp\u003EUnique three-dimensional solar cells that capture nearly all of the light that strikes them could boost the efficiency of photovoltaic (PV) systems while reducing their size, weight and mechanical complexity.  \u003C\/p\u003E\n\u003Cp\u003EThe new 3D solar cells capture photons from sunlight using an array of miniature \u0027tower\u0027 structures that resemble high-rise buildings in a city street grid.

The researchers first coat the wafer with a thin layer of iron using a photolithography process that can create a wide variety of patterns.  The patterned wafer is then placed into a furnace heated to 780 degrees Celsius.  Hydrocarbon gases are then flowed into furnace, where the carbon and hydrogen separate.  In a process known as chemical vapor deposition, the carbon grows arrays of multi-walled carbon nanotubes atop the iron patterns.\n\u003C\/p\u003E\n\u003Cp\u003EOnce the carbon nanotube towers have been grown, the researchers use a process known as molecular beam epitaxy to coat them with cadmium telluride (CdTe) and cadmium sulfide (CdS) which serve as the p-type and n-type photovoltaic layers.

Highlights include:\n\u003C\/p\u003E\n\u003Cp\u003E- In comparison with the late 1970s, total emissions have declined in the 20-county metro area CAF\u00c3\u0089 tracks. This measure peaked in the early 1980s and has declined since then, despite a doubling of the Atlanta fleet size. \u0022Whether we can continue this trend indefinitely is a different question as Atlanta continues to grow,\u0022 Rodgers says.\n\u003C\/p\u003E\n\u003Cp\u003E- Newer, cleaner-burning fuels have had a very positive effect - comparable to the inspections program - in reducing vehicle emissions.\n\u003C\/p\u003E\n\u003Cp\u003E- Also, only 1 percent of vehicles in the Atlanta fleet now run on carburetor-based systems. The second generation of fuel injection vehicles has helped reduce emissions.\n\u003C\/p\u003E\n\u003Cp\u003E- As vehicles became more durable in the early 1990s, Atlantans kept their automobiles longer. But a new-car-buying trend began in Atlanta by the end of the 1990s and lasted for several years. Even though more vehicles are on the road now, per vehicle emissions has declined by about half.\u0022It\u0027s an open question as to what we\u0027ll see between 2009 and 2012 when these vehicles are much older,\u0022 Rodgers says.\n\u003C\/p\u003E\n\u003Cp\u003E- Researchers monitored the rise of the minivan and the sport utility vehicle (SUV). When they began monitoring, the Atlanta fleet was composed mostly of passenger vehicles and trucks. Minivans became popular in the early 1990s and then SUVs by the mid-1990s. Now, large SUVs, minivans and pick-up trucks dominate the fleet. These vehicle types also have demonstrated a comparable reduction in emissions.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We\u0027ve been able to monitor these changes as they have occurred, so it\u0027s been enormously enlightening,\u0022 Rodgers says.\u0022We\u0027re not speculating on whether what we think is true is true; we can actually look at the data.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ERodgers also conducts research on vehicle emissions modeling under his joint appointment in the Georgia Tech School of Civil and Environmental Engineering. \n\u003C\/p\u003E\n\u003Cp\u003EThe Mobile Emission Assessment System for Urban and Regional Evaluation (MEASURE) model he helped develop estimates vehicle production of carbon monoxide, volatile organic compounds and oxides of nitrogen in space and time. MEASURE differs from previous models in that it estimates vehicle emissions as a function of vehicle operating modes - such as cruise and idle - rather than average vehicle speeds.

A low tide and wind-driven waves disguised the signs of receding water, so when the tsunami struck, it caught even lifeguards by surprise.  That contributed to the death toll of more than 600 persons in Java, Indonesia.\u003C\/p\u003E\n\u003Cp\u003E\u0022The general assumption was that if you were near the coast where the earthquake took place, you would feel it and be able to run to higher ground,\u0022 said Hermann Fritz, first author of a new \u003Cem\u003EGeophysical Research Letters \u003C\/em\u003Epaper about the July 17, 2006 tsunami.  \u0022This event caught people by surprise and showed that it\u0027s not always that simple.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe earthquake was slow rupturing, so it didn\u0027t produce strong ground shaking on Java that might have alerted people on the beach, he explained.\n\u003C\/p\u003E\n\u003Cp\u003ENo local warning was issued for the tsunami waves, which arrived only tens of minutes after the earthquake.  Fortunately, the event took place on a Monday.  Had the massive waves hit the day before, which was a major national holiday, the popular beach would have been much more crowded - and the toll higher.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Warning systems typically don\u0027t work very well for locations near earthquakes, where there are only tens of minutes between the earthquake and the tsunami\u0027s arrival,\u0022 noted Fritz, a Georgia Institute of Technology assistant professor who led an inspection team to Java a week after the event.  \u0022It\u0027s pretty much a spontaneous self-evacuation.  You normally feel the earthquake or see the ocean withdraw. If you hear the noise in the last tens of seconds before it hits, then it\u0027s just a matter of who makes it and who doesn\u0027t.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe survey team, which included scientists from five different countries, interviewed survivors and studied evidence left behind by the tsunami, including debris fields.  Beyond the quiet nature of the catastrophe, they discovered evidence of a 21-meter (65-foot) wave that hit a portion of the coastline near the island of Nusa Kambangan, indicating a second event that may have added to the severity of the disaster.\n\u003C\/p\u003E\n\u003Cp\u003EElsewhere along the 300 kilometers of coastline studied by the International Tsunami Survey team, the waves ranged from 5 to 7 meters, 16 to 24 feet.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This event indicates that there was likely a combination of both a tectonic tsunami and a submarine landslide or a canyon failure triggered by the earthquake,\u0022 said Fritz, whose research is supported by the U.S. National Science Foundation. \u0022The runup was unusually high along one portion of the coast, too much for a 7.8 magnitude earthquake.  The only explanation we could think of is that a submarine mass movement triggered by the earthquake could have added to the effect of the earthquake, given the essentially straight coastline with little room for large-scale tsunami focusing.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EFor people in seismically-active areas like Indonesia, an earthquake usually provides the first warning of a tsunami.  Whether caused by an earthquake or an underwater landslide, the first visible sign of an oncoming tsunami is often a rapid withdrawal of the ocean that exposes the seafloor or coral reefs.  When that appears, the first tsunami wave won\u0027t be far behind.\n\u003C\/p\u003E\n\u003Cp\u003EIn the July 2006 Java tsunami, lifeguards did not notice the withdrawal because the water was receding anyway because of a normal low tide - and because of large wind-produced waves.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The lifeguards did not recognize the precursors of the tsunami, either the shaking of the earth or the drawing down of the sea,\u0022 said Fritz, who also interviewed survivors of the 2004 Indonesian tsunami.  \u0022The irony is that many of the lifeguards survived because they were in tall concrete structures sitting more than four meters above the ground, getting just their feet wet - a classic example of vertical evacuation in engineered structures.  We interviewed one of them, and it was quite moving.  It was his job to watch out for the people on the beach, and what happened was pretty tough on him.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ESurvivors compared the sound of the tsunami to that of an aircraft landing or a loud boiling sound.  \u0022That primarily comes from the bore forming, or breaking of the waves a couple of hundred meters off shore,\u0022 Fritz explained.  \u0022In high impact areas, the first tsunami wave then comes in as a rolling wave of water, whereas in low-impact areas it may only be recognized as an unusually fast and high tide.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EA tsunami normally produces more than one wave, and the waves can be 10 or 20 minutes apart.  Often, the second or third wave is the largest, so many deaths occur when victims return to low-lying areas to look for relatives or assess damage after the first wave hits.\n\u003C\/p\u003E\n\u003Cp\u003EIn Indonesia, the government has instituted education programs to help residents respond to tsunami warning signs by quickly moving to higher ground.  In many cases, safety can mean moving a mile inland or 10 meters up a hill.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022It\u0027s always going to be difficult to provide a warning in Java because the earthquake zone is so near,\u0022 explained Fritz, a faculty member at Georgia Tech\u0027s Savannah, Ga. campus.  \u0022It\u0027s most critical for people to be able to evacuate themselves.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn other locations, such as the Hawaiian Islands, warning systems are useful because tsunamis caused by continental earthquakes take hours to reach the islands, he said.\n\u003C\/p\u003E\n\u003Cp\u003EIn the deep ocean, tsunami waves move at the speed of a jet aircraft.

Determining the properties of water on the nanoscale may prove important for biological and pharmaceutical research as well as nanotechnology. The research appears in the March 15 issue of the journal Physical Review B.\u003C\/p\u003E\n\u003Cp\u003EIn its bulk liquid form, water is a disordered medium that flows very readily. When most substances are compressed into a solid, their density increases. But water is different; when it becomes ice, it becomes less dense. For this reason, many scientists reasoned that when water is compressed (as it is in a nanometer-sized channel), it should maintain its liquid properties and shouldn\u0027t exhibit properties that are akin to a solid. Several earlier studies came to that very conclusion - that water confined in a nano-space behaves just like water does in the macro world. Consequently, a number of scientists considered the case to be closed.\n\u003C\/p\u003E\n\u003Cp\u003EBut when Georgia Tech experimental physicist Elisa Riedo and her team directly measured the force of pure water in a nanometer-sized channel, they found evidence suggesting that water was organized into layers. Riedo conducted these measurements by recording the force placed on a silicon tip of an atomic force microscope as it compressed water.  The water was confined in a nanoscale thin film on top of a solid surface. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Since water usually has a low viscosity, the force you would expect to feel as you compress it should be very small,\u0022 said Riedo, assistant professor in Georgia Tech\u0027s School of Physics. \u0022But when we did the experiment, we found that when the distance between the tip and the surface is about one nanometer, we feel a repulsive force by the water that is much stronger than what we would expect.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAs the tip compresses the water even more, the repulsive force oscillates, indicating that the water molecules are forming layers. As the tip continues to increase its pressure on a layer, the layer collapses and the water flows out horizontally.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022In effect, the confined water film behaves effectively like a solid in the vertical direction by forming layers parallel to the confining tip and surface, while maintaining its liquidity in the horizontal direction where it can flow out - resembling some phases of liquid crystals,\u0022 said Uzi Landman, director of the Center for Computational Materials Science, Regents\u0027 and Institute professor, and Callaway Chair of Physics at Georgia Tech.\n\u003C\/p\u003E\n\u003Cp\u003EA theoretical physicist, Landman conducted the first-ever computer simulations of these forces for tip-confined water films and found good correspondence between his team\u0027s theoretical predictions and the experiments. \n\u003C\/p\u003E\n\u003Cp\u003ESo why did Riedo and Landman\u0027s results differ from their peers? According to Landman, most previous studies on confined water were limited by technology at the time and could not directly measure the behavior in the last two nanometers. Instead they had to measure other properties and infer the forces acting in films of one nanometer thickness or less. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022If you want force, it is preferable to measure it,\u0022 he said. \u0022This is the first experiment to directly measure the force and it\u0027s the first simulation done of these forces. The fact that we have direct measurements married with theoretical results is rather conclusive.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ERiedo and Landman conducted their experiments in several different environments. They found that the layering effect was more pronounced when water was placed on top of hydrophilic surfaces that allow water to wet the solid surface, such as glass. When the water was confined by hydrophobic surfaces where water tends to bead up, like graphite, the effect was still present, but less pronounced.\n\u003C\/p\u003E\n\u003Cp\u003EAt the same time, Riedo\u0027s team was measuring the vertical force exerted on the tip by the confined water film, they also measured the film viscosity by measuring the lateral force. They found that when water was placed on a hydrophilic surface, the viscosity began to increase dramatically as the thickness of the confined film reached the 1.5 nanometer range. As they continued to compress the water and measure the lateral forces, the viscosity increased by a factor of 1,000 to 10,000.\n\u003C\/p\u003E\n\u003Cp\u003EOn hydrophobic surfaces, they did not see such an increase in viscosity. The results of the molecular dynamics simulations support these findings, showing a dramatically decreased mobility for sub-nanometer thick water films under hydrophilic confinement. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Water is a wonderful lubricant,\u0022 said Riedo, \u0022but it flows too easily for many applications. At the one nanometer scale, water is a viscous fluid and could be a much better lubricant.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EUnderstanding the properties of water at this scale could also be important for biological and pharmaceutical research, especially in understanding processes that depend on hydrated ionic transport through nanoscale channels and pores.\n\u003C\/p\u003E\n\u003Cp\u003ERiedo and Landman\u0027s next steps are to introduce impurities in the water to study how that affects its properties.\n\u003C\/p\u003E\n\u003Cp\u003ETai-De Li, Robert Szoszkiewicz and Jianping Gao also contributed to this research, which was supported by the National Science Foundation, the American Chemical Society Petroleum Foundation, the Air Force Office of Scientific Research and the U.S. Department of Energy.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"A Georgia Tech research team has discovered that water exhibits very different properties when it is confined to channels less than two nanometers wide - behaving much like a viscous fluid with a viscosity approaching that of molasses.

In a new study of chemo patients, scientists at the Georgia Institute of Technology and the Ovarian Cancer Institute found that 70 percent of subjects whose tumors had mutations in the gene p53 were still alive after five years. Patients with normal p53 displayed only a 30 percent survival rate. The findings raise the possibility of a new strategy for fighting cancer - namely, developing drugs to disable the functioning of this gene in the tumors of patients undergoing chemotherapy. The results appear in the May 16 edition of the open access journal PLoS ONE.\u003C\/p\u003E\n\u003Cp\u003E\u0022P53 has long been recognized as a key player in directing chemotherapy-damaged cancer cells to self annihilate, but less attention has been paid to p53\u0027s role in repairing damaged cells,\u0022said John McDonald, chair of Georgia Tech\u0027s School of Biology and chief research scientist at the Ovarian Cancer Institute.\n\u003C\/p\u003E\n\u003Cp\u003EWhen a cell is malfunctioning or injured, the gene p53 is called into action and tries to repair the cell. If the cell can\u0027t be repaired, p53 starts a process known as apoptosis that kills the cell. It\u0027s p53\u0027s role as one of the genes involved in initiating cell death that has led cancer researchers to long believe that the gene is essential to successful chemotherapy. The idea is that p53 assists in killing the cancerous cells that the chemo treatment injures.\n\u003C\/p\u003E\n\u003Cp\u003EBut in this latest trial, Georgia Tech researchers found that p53 may be a \u0027double-edged sword.\u0027 Chemotherapy patients whose tumors had a mutated p53 gene that didn\u0027t work had a much better survival rate than those who had normal p53.\n\u003C\/p\u003E\n\u003Cp\u003EIn the study, researchers took malignant and benign ovarian tumors straight from the operating room and compared their gene expression profiles. Some of the cancer patients had been treated with chemotherapy prior to surgery, and some had not. At this point researchers didn\u0027t consider whether the patients actually had malignant tumors or had been treated with chemotherapy. However, they found that the gene expression profiles of the tumors clustered the chemotherapy-treated patients into two groups: those whose profiles were similar to cancer patients who had not been treated with chemo and those whose profiles were similar to patients with benign tumors.\n\u003C\/p\u003E\n\u003Cp\u003EAs they continued their analysis, they found that the main difference between the groups\u0027 genetic profiles was the gene p53. While both groups had roughly the same amount of the protein encoded by p53, the cancer group had mutations in their p53 that caused the gene\u0027s corresponding protein not to function.The benign group\u0027s p53 was normal.\n\u003C\/p\u003E\n\u003Cp\u003EFive years later, only 30 percent of the chemotherapy cancer patients clustering in the benign group were alive, while 70 percent of those clustering in the cancer group were still alive. The stage of cancer at the time of surgery had no correlation to who survived and who didn\u0027t. What did seem to have an effect was whether p53 was working or not in the chemotherapy-treated tumors.\n\u003C\/p\u003E\n\u003Cp\u003EA standard belief in cancer research is that a working p53 is essential in helping chemo patients because it turns on the killing mechanism for the cells that were damaged by chemo. But McDonald points out that p53 can also help repair damaged cells. If p53 is repairing cancer cells, that may lead to cancer recurrence.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We think p53 may actually help some cancer cells make a comeback,\u0022 he said. \u0022Based on our results, we propose that p53 may help repair some of the cancer cells damaged by chemotherapy leading to tumor recurrence and explaining the higher mortality rate of patients whose tumors had a functioning p53. If we are correct, inhibiting p53 in tumors being treated with chemotherapy may substantially improve patients\u0027 long-term survival.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EMcDonald and colleagues are continuing to test their theory by conducting studies in cell cultures and mice. If it bears out, then disabling the gene in tumors, through medications or new genetic techniques during chemotherapy may help patients survive.\n\u003C\/p\u003E\n\u003Cp\u003EIn addition to McDonald, the research team consisted of: Benedict Benigno, gynecologic oncologist and founder of the Ovarian Cancer Institute; Lilya Matyunina, Erin B.

Other applications include LED-based indicator lamps and solid-state light sources like those in flashlights and large display panels such as the NASDAQ sign in Times Square. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022MOCVD is used for virtually all high-brightness LEDs in traffic signals, automotive lighting, and LCD back lighting, and soon this technology will be widely used to illuminate public buildings and eventually your home,\u0022 said Dupuis. \u0022I hope that my students can use the knowledge they gain at Georgia Tech and contribute to even greater future advances in this field.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ELED technology, based on Dupuis\u0027 MOCVD process, is already transforming the lighting industry. LEDs provide a highly efficient and reliable light source. As they become increasingly useful for general illumination and displace the incandescent light bulb, the United States will save billions in energy costs. Carbon emissions from traditional power plants will also be significantly reduced. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022The Edison Medal is a very special and truly wonderful honor for me, both because of the outstanding and innovative inventor and engineer for whom it is named and for the very many truly exceptional individuals who have received it before me,\u0022 remarked Dupuis. \u0022I am especially honored to acknowledge the impact that Dr. Nick Holonyak Jr., has had on my academic and professional career.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EHolonyak was Dupuis\u0027 thesis advisor and mentor at the University of Illinois at Urbana-Champaign, where Dupuis earned his B.S. (with Highest Honors--Bronze Tablet), his M.S., and his Ph.D. in electrical engineering. Holonyak was instrumental in launching the field of multi-element semiconductors, and Dupuis has continued his own research in this area, specializing in semiconductor materials and devices, epitaxial growth, and heterojunction devices in III-V compound semiconductors. He currently directs the Center for Compound Semiconductors at Georgia Tech. \n\u003C\/p\u003E\n\u003Cp\u003EA Georgia Research Alliance Eminent Scholar, Dupuis has received many awards and distinctions. Among these is the 2002 National Medal of Technology, the nation\u0027s highest honor for work in science and technology. President George W. Bush awarded this medal to Dupuis and two colleagues for their work on developing and commercializing LEDs. \n\u003C\/p\u003E\n\u003Cp\u003EDupuis is a member of the National Academy of Engineering and a Fellow of the IEEE, the American Physical Society, the American Association for the Advancement of Science and the Optical Society of America. An author of more than 360 technical papers in refereed journals and a sought-after lecturer, he has held numerous leadership positions within IEEE and the IEEE Lasers and Electro-Optics Society, as well as with various conferences and workshops associated with semiconductor devices in the optoelectronic and photonics areas. \n\u003C\/p\u003E\n\u003Cp\u003EBefore joining Georgia Tech in 2003, Dupuis held the Judson S. Swearingen Regents Chair in Engineering at the University of Texas at Austin for 14 years. He previously worked in industry positions at AT\u0026amp;T Bell Laboratories, Rockwell International and Texas Instruments. \n\u003C\/p\u003E\n\u003Cp\u003EThe Edison Medal is the oldest medal in engineering. It was created by Thomas Edison\u0027s friends and associates in 1904, 25 years after Edison introduced his incandescent electric light bulb.

As a scientist you\u0027re curious about how things work; you don\u0027t have to pretend that you\u0027re interested because you really are,\u0022 said Azizi, a postdoctoral researcher at the Georgia Institute of Technology. She earned her doctorate in biochemistry at Tech.\n\u003C\/p\u003E\n\u003Cp\u003EThe pilot undertakes two main stories and several smaller ones. The first segment, hosted by British physicist Basil Singer and best-selling science writer and filmmaker Victoria Bruce, investigates Neanderthal DNA and answers whether it can be used someday to bring them back to life. The segment was spurred by questions that a Connecticut middle school teacher submitted on behalf of her class.\n\u003C\/p\u003E\n\u003Cp\u003EIn her first segment, Azizi and co-host astrophysicist Kevin Hand examine why a certain species of frogs has disappeared from Long Island, NY and how it may be an early warning for humans. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022That\u0027s a very serious issue because any changes in the environment, even small changes, they can detect,\u0022 said Azizi. \u0022And if we have a die-off of certain types of species, that means there\u0027s something in our environment that\u0027s affecting us, but we may not be able to feel it, yet.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EDuring the segment, Azizi enlists the help of the amphibian conservation program at the Atlanta Botanical Garden to help them understand what may be responsible for the disappearing frog species on Long Island. \n\u003C\/p\u003E\n\u003Cp\u003EIn Azizi\u0027s other segment she takes a spin in an electric race car that accelerates from 0 mph to 60 mph in three seconds. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022We were going, I think, 120 mph, but when Kenny Shepherd, the NASCAR driver, got in there he actually took the car even faster,\u0022 she said.\n\u003C\/p\u003E\n\u003Cp\u003EAzizi said she was looking for faculty jobs on a science career Web site when she saw the posting looking for a host of the show. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022I thought, oh yeah, I\u0027ll apply, whatever,\u0022 she said, not really expecting much. \u0022But then I got a callback to send in my picture and then to send in my tape.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAfter not hearing from the producers for a while, and just as she had given up hope, she got a call asking her to fly to Oregon to interview a professor for the frog segment. \n\u003C\/p\u003E\n\u003Cp\u003EAll in all, filming the pilot took about six days. Azizi said she flew to San Francisco to film at the Altamont race track, filmed lab segments in New York, and interviewed people at the Atlanta Botanical Garden. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022It\u0027s been much fun.

The experiments, in conjunction with the theoretical analysis performed by the Georgia Tech team, show near perfect agreement pertaining to the cluster structures occurring in the experiments. Understanding the electronic and geometric structures of gold nanoclusters is a key step towards understanding their behavior under different conditions, such as their use as nanocatalysts or in certain medical applications. The results appear in separate papers in The Physical Review B and in the journal ChemPhysChem.\u003C\/p\u003E\n\u003Cp\u003EIn its bulk form, gold is treasured for its property as a non-reactive metal. Its use in electronics, dentistry, jewelry and art, depends on this inertness. But at the nano scale, when gold clusters contain only a small number of atoms, gold shows very different properties, which exhibit chemical reactivity that make them potent catalysts. Because their chemical and physical properties depend greatly on their physical structures, significant efforts have been invested by scientists to determine what the most stable configurations of gold clusters are in this size range. Understanding this is of great importance for elucidating the chemical properties of these clusters and in research aiming to discover the physical patterns that govern how the clusters are put together.\n\u003C\/p\u003E\n\u003Cp\u003EBetween 2000 and 2002, a Georgia Tech team, led by Uzi Landman, director of CCMS, Regents\u0027 and Institute professor, and Callaway chair of physics at Georgia Tech,  predicted that negatively charged gold nanoclusters, up to 13 atoms in size, would exhibit  two-dimensional, flat structures. The appearance of two-dimensional structures for such relatively large metal clusters is unique to gold, and the researchers showed that it is related to the strong relativistic effects for this metal. When these predictions were verified experimentally, research in Landman\u0027s group and in other places focused on what happens when the nanoclusters are even larger.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We wanted to know, what happens after 13 atoms,\u0022 said Landman. \u0022What happens when these clusters become three-dimensional and what is their structural motif?\u0022 For the past few years, scientists at the CCMS have made theoretical predictions about the structures of gold nanoclusters in the larger size range. Now, working with two independent experimental groups, Landman and his collaborators have found firm evidence pertaining to the size-dependent structural development of these nanoclusters.\n\u003C\/p\u003E\n\u003Cp\u003EOne of these collaborations involved researchers from the University of Freiburg and the Fraunhofer Institute for Mechanics of Materials, both in Germany, and a scientist from the University of Jv\u00c3\u00a4skyl\u00c3\u00a4 in Finland. The Freiburg team performed photoemission experiments, in which a laser is shot at the gas-phase cluster causing it to eject an electron. Measuring the energy profiles of the emitted electrons using lasers of different wavelengths allowed the researchers to gain knowledge about the occupied electronic energy levels in the clusters. The distribution of these levels depends on the specific geometric arrangement of atoms in the clusters. Indeed, the theoretical analysis of the correlation between the distributions of the electronic energy levels and the atomic spatial arrangements allowed the researchers to determine the clusters\u0027 electronic properties, as well as geometric structures.\n\u003C\/p\u003E\n\u003Cp\u003EIn the other collaboration, the Georgia Tech researchers worked with a team from the Rowland Institute at Harvard University. They used electron diffraction, a technique in which a beam of electrons is fired at the clusters, causing the electrons to scatter.  By measuring the intensity of the scattered electrons and comparing it to the change in momenta of the electrons caused by their collisions with the atoms of the clusters, they obtaines information about the spatial arrangements of the atoms in the clusters. Theoretical analysis of the interference patterns in these measured intensities allowed them to determine the clusters\u0027 structures.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022It turns out that close to all the stable structures that were found through our theoretical analysis of the photoemission measurements were the same as those that emerged from analysis of the electron scattering experiments,\u0022 said Landman. \u0022In our analysis we have used first-principles electronic structure calculations based on density-functional theory, in conjunction with structural optimization techniques. This is likely the first time that two separate and independent experimental tools, in conjunction with a common theoretical analysis, have shown such a high degree of agreement in the challenging area of structural determination of nano clusters.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ETo avoid any bias, and ensure that the groups\u0027 analyses weren\u0027t being unintentionally influenced by knowledge of each other, neither experimental group saw the results of the other until the publication of their respective papers.\n\u003C\/p\u003E\n\u003Cp\u003EThe results of the Georgia Tech collaborative investigations with the European group are published in the journal ChemPhysChem Volume 8, (2007), and those obtained from the collaboration with the Rowland Institute are published in The Physical Review B volume 74, (2006).\n\u003C\/p\u003E\n\u003Cp\u003EThrough this comparison between experiment and theory, the teams found that the clusters start out as two-dimensional structures till 13 or 14 atoms in size, changing to three-dimensional hollow cages from about 16 atoms, and developing a face-centered-cubic tetrahedral structure at 20 atoms, resembling the bulk gold crystalline structure.  However, at 24 atoms the gold clusters take an unexpected capped tubular cigar shape.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022These results assist us not only in determining the structures of the clusters, but also provide insight into the factors that underlie their self-assembly,\u0022 said Landman. \u0022In some ways, we are determining the \u0027structural grammar\u0027 of these gold nanoclusters and by understanding that, we may better understand what motifs appear as we continue to search for the structures of clusters larger than 24 atoms.\n\u003C\/p\u003E\n\u003Cp\u003EThe Georgia Tech team consisted of Uzi Landman and research scientist Bokwon Yoon.

The Graduate Program in Digital Media is in the School of Literature, Communication and Culture (LCC) in the Ivan Allen College of Liberal Arts at Georgia Tech.\u003Cbr \/\u003E\n\u003Ca href=\u0027http:\/\/www.dm.gatech.edu\u0027\u003Ehttp:\/\/www.dm.gatech.edu\u003C\/a\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EAbout the GVU Center\u003C\/strong\u003E\u003Cbr \/\u003E\nThe GVU Center is a university-wide, interdisciplinary research center that spans the Georgia Tech campus and includes many outside collaborators.

In a collaborative investigation performed by an experimental team and a theoretical physics team, the group discovered that measured fluctuations in the smallest nanowires\u0027 conductance are caused by a pair of atoms, known as a dimer, shuttling back and forth between the bulk electrical leads. Determining the structural properties of nanowires is a big challenge facing the future construction of nanodevices and nanotechnology. The paper appears in the January 26th issue of Physical Review Letters.\u003C\/p\u003E\n\u003Cp\u003E\u0022By combining the data from the electrical conductance experiments with high-level first principles quantum mechanical calculations, we\u0027ve been able to draw an accurate picture of the physical mechanisms that govern these properties. It\u0027s like measuring current through an object you can\u0027t see to tell you what it looks like,\u0022 said Uzi Landman, director of the Center for Computational Materials Science, Regents\u0027 and Institute professor, and Callaway chair of physics at Georgia Tech.\n\u003C\/p\u003E\n\u003Cp\u003ELeading the experimental team, Alexei Marchenkov, assistant professor in the School of Physics, formed niobium nanowires using the mechanically controlled break junction technique - that is bending a thin nanofabricated strip of niobium until it breaks. In the final stage before the strip breaks completely, all that\u0027s left is a nanowire made of a short chain of niobium atoms that bridge the gap between the two sides of the strip. Working at low temperatures, Marchenkov was able to hold the nanowires at successive stretching stages for many hours, long enough to perform thorough conductance measurements, and much longer than the seconds typically characteristic of this technique.\n\u003C\/p\u003E\n\u003Cp\u003EConducting the experiment at 4.2 degrees Kelvin (far below niobium\u0027s superconductivity transition temperature of 9.2 Kelvin), as well as performing measurements  above the transition temperature, Marchenkov\u0027s team measured the electrical conductance of the atomic nanowire as it is stretched during the bending of the strip. As this bending occurs, the atoms separate from each other. The researchers were capable of controlling this separation with a precision better than 1 picometer (one thousandth of a nanometer), which is about 100 times smaller than the typical size of atoms.\n\u003C\/p\u003E\n\u003Cp\u003EAs the nanowire is slowly pulled, the conductance drops. The drop in conductance was gradual until a rapid decrease in the conductance was observed in a narrow region of just 0.1 angstrom . Upon further pulling of the wire, the conductance resumed its gradual decline.\u003C\/p\u003E\n\u003Cp\u003E\u0022Focusing on this narrow region, we found that this steep drop in conductance wasn\u0027t as smooth as it seemed at first,\u0022 said Marchenkov. \u0022We saw that the conductance actually jumps between two values.  Close to the onset of the rapid drop, the conductance was mostly rather high and then there would be random short periods were it drops to a significantly lower value. On the other side of the interval, the pattern reversed itself and  mostly the low conductance values were spotted with  the random occurrence of sharp  spikes of high conductance,\u0022 said Marchenkov.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022That\u0027s where the theoretical simulations come in,\u0022 said Landman. \u0022We needed to find out what physical phenomenon would account for these sharp drops and spikes in the conductance.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAt first, the team thought a single atom must be randomly shuttling itself back and forth between two positions in the space separating the electrical leads, but the data didn\u0027t fit. So, they tried running the simulations with a connected pair of atoms, or dimer.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022When we performed electronic structure and electrical conductance calculations on a shuttling dimer, we found good agreement with the experimentally measured conductance and its variation with the wire length,\u0022 said Landman.\n\u003C\/p\u003E\n\u003Cp\u003EWhen the dimer is closer to one lead, the electrons that make up the electrical current have a longer way to hop from the dimer to the other lead, making current flow more difficult. When the dimer is in the center between the leads, the distance the electrons have to hop is shorter and more manageable, allowing the current to flow better.

But when audiences in the back row were able to hear music and voices with amazing clarity (well before any theater had the luxury of a sound system), the Greeks must have known that they had done something very right because they made many attempts to duplicate Epidaurus\u0027 design, but never with the same success.\u003C\/p\u003E\n\u003Cp\u003EResearchers at the Georgia Institute of Technology have pinpointed the elusive factor that makes the ancient amphitheater an acoustic marvel. It\u0027s not the slope, or the wind - it\u0027s the seats. The rows of limestone seats at Epidaurus form an efficient acoustics filter that hushes low-frequency background noises like the murmur of a crowd and reflects the high-frequency noises of the performers on stage off the seats and back toward the seated audience member, carrying an actor\u0027s voice all the way to the back rows of the theater. \n\u003C\/p\u003E\n\u003Cp\u003EThe research, done by acoustician and ultrasonics expert Nico Declercq, an assistant professor in the Woodruff School of Mechanical Engineering at Georgia Tech and Georgia Tech Lorraine in France, and Cindy Dekeyser, an engineer who is fascinated by the history of ancient Greece, appears in the April issue of the Journal of the Acoustical Society of America.\n\u003C\/p\u003E\n\u003Cp\u003EWhile many experts speculated on the possible causes for Epidaurus\u0027 acoustics, few guessed that the seats themselves were the secret of its acoustics success. There were theories that the site\u0027s wind - which blows primarily from the stage to the audience - was the cause, while others credited masks that may have acted as primitive loudspeakers or the rhythm of Greek speech. Other more technical theories took into account the slope of the seat rows.\n\u003C\/p\u003E\n\u003Cp\u003EWhen Declercq set out to solve the acoustic mystery, he too had the wrong idea about how Epidaurus carries performance sounds so well. He suspected that the corrugated, or ridged, material of the theater\u0027s limestone structure was acting as a filter for sound waves at certain frequencies, but he didn\u0027t anticipate how well it was controlling background noise.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022When I first tackled this problem, I thought that the effect of the splendid acoustics was due to surface waves climbing the theater with almost no damping,\u0022 Declercq said. \u0022While the voices of the performers were being carried, I didn\u0027t anticipate that the low frequencies of speech were also filtered out to some extent.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EBut as Declercq\u0027s team experimented with ultrasonic waves and numerical simulations of the theater\u0027s acoustics, they discovered that frequencies up to 500 Hz were held back while frequencies above 500 Hz were allowed to ring out. The corrugated surface of the seats was creating an effect similar to the ridged acoustics padding on walls or insulation in a parking garage.\n\u003C\/p\u003E\n\u003Cp\u003ESo, how did the audience hear the lower frequencies of an actor\u0027s voice if they were being suppressed with other background low frequencies? There\u0027s a simple answer, said Declercq. The human brain is capable of reconstructing the missing frequencies through a phenomenon called virtual pitch. Virtual pitch helps us appreciate the incomplete sound coming from small loudspeakers (in a laptop or a telephone), even though the low (bass) frequencies aren\u0027t generated by a small speaker.\n\u003C\/p\u003E\n\u003Cp\u003EThe Greeks\u0027 misunderstanding about the role the limestone seats played in Epidaurus\u0027 acoustics likely kept them from being able to duplicate the effect. Later theaters included different bench and seat materials, including wood, which may have played a large role in the gradual abandonment of Epidaurus\u0027 design over the years by the Greeks and Romans, Declercq said.\u003Cem\u003E\u003C\/em\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"The theater at Epidaurus has been known for centuries as an acoustic marvel that allowed spectators to hear in the back row - without the aid of modern microphones or sound systems.

In the study, the researchers used operating income to measure profitability.

The median decline in return on sales ranged from 1.5 to 3.1 percent (mean decline of 12.6 to 19.6 percent), while the median decline in sales over assets ranged from 5.9 to 11.0 percent (mean decline of 9.3 to 11.5 percent).\n\u003C\/p\u003E\n\u003Cp\u003EAnnouncements of product delays decreased average shareholder value by about 12 percent, according to the researchers. \u0022Our results suggest that negative stock market reaction to product introduction delays is actually quite rational given the impact of delays on profitability,\u0022 they write.\n\u003C\/p\u003E\n\u003Cp\u003EReasons for delayed product launches vary, including poor management of the development process, lack of coordination among different functional areas, and shortages of resources, note the researchers. \u0022Our results underscore the importance of planning and executing the launch of new products,\u0022 Singhal says. \u0022More attention should be paid to product development and innovation issues.\u0022\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWriter:\u003C\/strong\u003E Brad Dixon, College of Management\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Study Shows Cost of Firms Failing to Launch Products on Time"}],"field_summary":[{"value":"As Microsoft recently demonstrated with its belated Office 2007 software package and Vista operating system, postponing new product launches can take a heavy toll on the bottom line, according to a new study.","format":"limited_html"}],"field_summary_sentence":[{"value":"Failure to launch products on time hurts profits"}],"uid":"27301","created_gmt":"2007-02-08 01:00:00","changed_gmt":"2016-10-08 03:01:37","author":"Elizabeth Campell","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2007-02-08T00:00:00-05:00","iso_date":"2007-02-08T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"hg_media":{"72343":{"id":"72343","type":"image","title":"Vinod Singhal","body":null,"created":"1449177454","gmt_created":"2015-12-03 21:17:34","changed":"1475894656","gmt_changed":"2016-10-08 02:44:16"}},"media_ids":["72343"],"related_links":[{"url":"http:\/\/mgt.gatech.edu\/directory\/singhal.html","title":"Singhal Faculty Page"}],"groups":[{"id":"1214","name":"News Room"}],"categories":[{"id":"139","name":"Business"},{"id":"145","name":"Engineering"},{"id":"135","name":"Research"}],"keywords":[{"id":"1072","name":"Business"},{"id":"2496","name":"launch"},{"id":"233","name":"Logistics"},{"id":"1052","name":"Management"},{"id":"2499","name":"operations"},{"id":"681","name":"product"},{"id":"2498","name":"profit"},{"id":"2497","name":"Vinod Singhal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003ELisa Grovenstein\u003C\/strong\u003E\u003Cbr \/\u003ECommunications \u0026amp; Marketing\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=lgrovenste3\u0022\u003EContact Lisa Grovenstein\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-8835\u003C\/strong\u003E","format":"limited_html"}],"email":["lisa.grovenstein@comm.gatech.edu"],"slides":[],"orientation":[],"userdata":""}},"72340":{"#nid":"72340","#data":{"type":"news","title":"Ga Companies Sign Health Reform Initiative at Tech","body":[{"value":"\u003Cp\u003EIn a meeting at the Georgia Institute of Technology, representatives from top Georgia companies and organizations such as The Coca Cola Co., AT\u0026amp;T, United Parcel Service, U.S. Centers for Disease Control and Prevention, the Georgia Hospital Association and the Georgia Chamber of Commerce joined Georgia Gov.

Now, seven years later they\u0027ve shown that it can be modified to work in the real world, too - that is, outside of a vacuum. The results appear in the February 9 issue of Physical Review Letters (PRL).\u003C\/p\u003E\n\u003Cp\u003EUnderstanding the motion of fluids is the basis for a tremendous amount of engineering and technology in contemporary life. Planes fly and ships sail because scientists understand the rules of how fluids like water and air behave under varying conditions. The mathematical principles that describe these rules were put forth more than 100 years ago and are known as the Navier-Stokes equations. They are well-known and understood by any scientist or student in the field. But now that researchers are delving into the realm of the small, an important question arisen: namely, how do these rules work when fluids and flows are measured on the nanoscale? Do the same rules apply or, given that the behavior of materials in this size regime often has little to do with their macro-sized cousins, are there new rules to be discovered?\n\u003C\/p\u003E\n\u003Cp\u003EIt\u0027s well-known that small systems are influenced by randomness and noise more than large systems. Because of this, Georgia Tech physicist Uzi Landman reasoned that modifying the Navier-Stokes equations to include stochastic elements - that is give the probability that an event will occur - would allow them to accurately describe the behavior of liquids in the nanoscale regime.\n\u003C\/p\u003E\n\u003Cp\u003EWriting in the August 18, 2000, issue of Science, Landman and post doctoral fellow Michael Moseler used computer simulation experiments to show that the stochastic Navier-Stokes formulation does work for fluid nanojets and nanobridges in a vacuum. The theoretical predictions of this early work have been confirmed experimentally by a team of European scientists (see the December 13, 2006, issue of Physical Review Letters).  Now, Landman and graduate student Wei Kang have discovered that by further modifying the Moseler-Landman stochastic Navier-Stokes equations, they can accurately describe this behavior in a realistic non-vacuous environment.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022There was a strong opinion that fluid dynamics theory  would stop being valid for small systems,\u0022 said Landman, director of the Center for Computational Materials Science, Regents\u0027 and Institute professor, and Callaway chair of physics at the Georgia Institute of Technology. \u0022It was thought that all you could do was perform extensive, as well as expensive, molecular dynamic simulations or experiments, and that continuum fluid dynamics theory could not be applied to explain the behavior of such small systems.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe benefit of the new formulations is that these equations can be solved with relative ease in minutes, in comparison to the days and weeks that it takes to simulate fluid nano structures, which can contain as many as several million molecules. Equally difficult, and sometimes even harder, are laboratory experiments on fluids in this regime of reduced dimensions.\n\u003C\/p\u003E\n\u003Cp\u003EIn this study, Landman and Wei  simulated a liquid propane bridge, which is a slender fluid structure connecting two larger bodies of liquid, much like a  liquid channel connecting two rain puddles. The bridge was six nanometers in diameter and 24 nanometers long. The object was to study how the bridge collapses.\n\u003C\/p\u003E\n\u003Cp\u003EIn the study performed in 2000, Landman simulated a bridge in a vacuum. The bridge broke in a symmetrical fashion, pinching in the middle, with two cones on each side. This time, the simulation focused on a model with a nitrogen gas environment surrounding the bridge at different gas pressures.\n\u003C\/p\u003E\n\u003Cp\u003EWhen the gas pressure was low (under 2 atmospheres of nitrogen), the breaking occurred in much the same way that it did in the previous vacuum computer experiment. But when the pressure was sufficiently high (above 3.5 atmospheres), 50 percent of the time the bridge broke in a different way. Under high pressure, the bridge tended to create a long thread and break asymmetrically on one side or the other of the thread instead of in the middle. Until now, such asymmetric long-thread collapse configuration has been discussed only for macroscopically large liquid bridges and jets.\n\u003C\/p\u003E\n\u003Cp\u003EAnalyzing the data showed that the asymmetric breakup of the nanobridge in a gaseous environment relates to molecular evaporation and condensation processes and their dependence on the curvature of the shape profile of the nanobridge.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022If the bridge is in a vacuum, molecules evaporating from the bridge are sucked away and do not come back\u0022 said Landman. \u0022But if there are gas molecules surrounding the bridge, some of the molecules that evaporate will collide with the gas, and due to these collisions  the scattered molecules may change direction and come back to the nanobridge and condense on it.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAs they return they may fill in spaces where other atoms have evaporated. In other words, the evaporation-condensation processes serve to redistribute the liquid propane along the nanobridge, resulting in an asymmetrical shape of the breakage. The higher the pressure is surrounding the bridge, the higher the probability that the evaporating atoms will collide with the gas and condense on the nanobridge. Landman and Wei have shown that these microscopic processes can be included in the stochastic hydrodynamic Navier-Stokes equations, and that the newly modified equations reproduce faithfully the results of their atomistic molecular dynamics experiments.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Knowing that the hydrodynamic theory, that is the basis of venerable technologies around us, can be extended to the nanoscale is fundamentally significant, and a big relief\u0022 said Landman. \u0022Particularly so, now that we have been able to use it to describe the behavior of nanofluids in a non-vacuous environment - since we expect that this is where most future applications would occur.\u0022\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ECaption for Photo one, hi-res download\u003C\/strong\u003E\u003Cbr \/\u003E\nA typical break-up process of a propane liquid bridge (blue) at 185 K in an ambient nitrogen gas (yellow) environment (density of 6:0 kg=m3, with a corresponding partial pressure of 0.36 MPa), recorded in a MD simulation at t=0 (a), 400 (b), 760 (c), and 840 ps (d).

But the hormone\u0027s effects are many and varied, lowering the activity of the immune system, helping create memories with short-term exposure, while impairing learning if there\u0027s too much for too long. Given the variety of its effects,understanding how cortisol is made is essential to producing medications that can alter its production. \n\u003C\/p\u003E\n\u003Cp\u003EScientists at the Georgia Institute of Technology have discovered an important step in cortisol production, finding that although the output of the hormone is continuous, the molecular production is cyclic in nature - involving a rhythmic binding and unbinding of a protein essential to its production. The research, which increases understanding of how the brain and the endocrine system work together to regulate health, appears in the February issue of the journal Molecular Endocrinology.\n\u003C\/p\u003E\n\u003Cp\u003ETurning cholesterol into the stress hormone cortisol involves many reactions and begins when the hypothalamus sends a signal to the adrenal glands. Proteins then flood into the nucleus to bind to the DNA, creating the gene CYP 17. What happens next is well understood; CYP 17, along with a battery of other enzymes, transforms cholesterol into cortisol. But what isn\u0027t understood is how this protein binding creates CYP 17, or which proteins are important. So, graduate students Eric Dammer and Adam Leon, along with Marion Sewer, assistant professor in Georgia Tech\u0027s School of Biology, decided to model the events that occur after the adrenal gland receives the signal.\n\u003C\/p\u003E\n\u003Cp\u003EOne of the things the signal does is cause adrenal cells to increase their production of cyclic AMP (cAMP), a chemical that encourages proteins to interact. So they began by causing the cells to make more cAMP. Then as the proteins assembled on the DNA, they tested the cells at different intervals in order to get a snapshot of which proteins were interacting, both with each other and the DNA and in which order this occurred. Then they mutated the proteins to stop them from fulfilling their roles.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022One of the best ways to try and figure out the function of a protein or a gene is to get rid of it or mutate it so that it\u0027s not acting normally. Then you compare it with one that is acting normally,\u0022 said Sewer.\n\u003C\/p\u003E\n\u003Cp\u003EIn this study, they focused on a protein known as steriodogenic factor 1 (SF-1), which is essential for making all steroid hormones. Researchers were interested in discovering what events have to occur in order for SF-1 to bind to DNA.\n\u003C\/p\u003E\n\u003Cp\u003EThe first thing they found was that because DNA is so tightly packed in the nucleus, SF-1 can\u0027t bind to it until it\u0027s unpacked by a group of proteins. Once that happens, SF-1 binds to the genes, beginning the process that makes CYP 17 and ultimately cortisol. But it\u0027s not a continuous process, they found.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Once SF-1 binds, it leaves. A few minutes later other proteins come in and condense the DNA,\u0022 said Sewer. \u0022After that SF-1 binds again, then leaves, and the proteins cause the DNA to contract again.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThis cycle goes on as long as the adrenal gland is receiving the signal.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Even though you get a sustained production of cortisol, the actual molecular events that happen in the nucleus are dynamic,\u0022 said Sewer. \u0022It\u0027s an extremely complex series of events that starts within minutes of the adrenal gland receiving the signal. Without all these transient binding events, the adrenal gland fails to produce optimal levels of cortisol.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ENext the team will investigate how small molecules - ligands - regulate cortisol production by binding to SF-1 and controlling the receptor\u0027s ability to bind to DNA.\n\u003C\/p\u003E\n\u003Cp\u003EThis research was supported by the National Institutes of Health, the National Science Foundation and the Georgia Cancer Coalition.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Georgia Tech biologists have discovered an important step in the production of the hormone cortisol production.

According to Gluzman, even though Kaplan wasn\u0027t successful in assassinating Lenin that day, he was seriously wounded. The bullets, which were never removed from his neck, are speculated by some historians to have caused the stroke that took his life six years later. \n\u003C\/p\u003E\n\u003Cp\u003EThe film was written by Gluzman\u0027s friend Wesley Wingo, a film student at New York University, and the original music was composed by Tech student Rolan Duvvury.

The system\u0027s goal is to provide consistent tumor-killing radiation doses to the tumor cells while limiting potentially damaging doses to nearby critical structures.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The system can be used in real time,\u0022 said Lee. \u0022The patient can come in, the imaging is done and we can then do the planning and implantation right away.

As a result, patients experience less pain and have faster recoveries.\n\u003C\/p\u003E\n\u003Cp\u003ENational distribution of this system will allow achievement of consistent treatment planning across different clinics, thus reducing the variability in the quality of treatment plans.

They are more brightly fluorescent, they resist photo bleaching and they can emit a broad range of colors simultaneously.\n\u003C\/p\u003E\n\u003Cp\u003EThese properties make bioconjugated quantum dots highly promising for improving the sensitivity of disease diagnosis in the laboratory, and they are particularly important for detecting and analyzing cancer biomarkers that are present at low concentrations or in small numbers of cells.

Such modification would decrease or eliminate the need for costly chemical pretreatments now required.\n\u003C\/p\u003E\n\u003Cp\u003E* Consolidated bioprocessing, which involves the use of a single microorganism or group of organisms to break down plant matter through a one-step conversion process of biomass into biofuels.\n\u003C\/p\u003E\n\u003Cp\u003EIn announcing the awards, Energy Secretary Samuel Bodman said, \u0022These centers will provide the transformational science needed for bioenergy breakthroughs to advance President Bush\u0027s goal of making cellulosic ethanol cost-competitive with gasoline by 2012, and assist in reducing America\u0027s gasoline consumption by 20 percent in 10 years. The collaborations of academic, corporate, and national laboratory researchers represented by these centers are truly impressive and I am very encouraged by the potential they hold for advancing America\u0027s energy security.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn addition to ORNL, other DOE Bioenergy Science Center partners include the University of Tennessee, Dartmouth College, the University of Georgia, the Samuel Roberts Noble Foundation, the National Renewable Energy Laboratory and companies ArborGen in Summerville, S.C.; Diversa (now Verenium Corp.) in San Diego, and Mascoma in Cambridge, Mass.
