From a technological point of view, it will be feasible to obtain engineering materials that retain the structural and chemical attributes of particles\/grains in the nanometer size range.\u0026nbsp; From scientific point of view, large-scale nanostructured materials will permit systematic investigations of the physical and mechanical behavior, as well as novel phenomena.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;Recently, severe plastic deformation (SPD), which encompasses mechanical alloying in liquid nitrogen (cryomilling) and high-pressure torsion, has emerged as a successful strategy for the synthesis of nanostructured alloys and composites. Results from various groups around the world reveal considerable improvements in the physical performance of a variety of SPD processed metals and alloys. While increases in strength of several 100% are commonly documented, ductility, however, appears to scale inversely with strength in these materials; this behavior has been attributed to limited dislocation activity at these length scales.\u0026nbsp; This challenge has been addressed via the introduction of additional size scales that facilitate plasticity during deformation.\u0026nbsp; The concept of a bimodal microstructure has recently been extended into the realm of metal composites with tri-modal microstructural characteristics, to accomplish ultra-high strength values.\u0026nbsp; In this lecture, published data of cryomilled alloys and composites are reviewed and discussed with particular emphasis on the following topics: recent findings in the area of cryomilled materials; primary consolidation and secondary processing methods; microstructural evolution from nanostructured powders to bulk materials during consolidation; and mechanical behavior of consolidated materials.\u0026nbsp; The deformation behavior and the underlying mechanisms of cryomilled materials are discussed in an effort to shed light into the fundamental behavior of ultrafine grained and nanostructured materials.\u003C\/p\u003E\u003Cp\u003EBIO:\u003C\/p\u003E\u003Cp\u003EEnrique J.

with promise to create cheaper, more efficient\nsolar cells. This work introduces a new type of 3D PV device based on\nvertically aligned carbon nanotube (CNT) arrays. These arrays are paired with\nthe thin film heterojunction, CdTe\/CdS, to form a complete 3D PV device\n(3DCNTPV).\u0026nbsp;\u003C\/p\u003E\n\n\u003Cp\u003EThe main benefit of the 3DCNTPV cell is the ability to utilize\nmultiple photon interactions with the solar cell surface. This three\ndimensionality allows photons to interact multiple times with the photoactive\nmaterial, which increases the absorption and the overall power output over what\nis possible with a two dimensiona (2D) morphology.

The degree of randomness of the monomer\nsequence for the random and the blocky copolymers, were 1.170 and 0.104,\nrespectively, and the degree of polymerization was fixed at 50.\u0026nbsp; The equilibrated density of the hydrogel was\nfound to be larger for the random sequence than for the blocky sequence at low\nwater contents (\u0026lt; 40 wt %), but this density difference decreased with\nincreasing water content.\u0026nbsp; The pair\ncorrelation function analysis shows that VP is more hydrophilic than HEMA and\nthat the random sequence hydrogel is solvated more than the blocky sequence\nhydrogel at low water content, which disappears with increasing water content.\u003C\/p\u003E\n\n\u003Cp\u003ECorrespondingly, the water structure is more disrupted by\nthe random sequence hydrogel at low water content but eventually develops the\nexpected bulk-water-like structure with increasing water content.\u0026nbsp;

The monomeric sequence effect on\nthe P(VP-co-HEMA) hydrogel is clearly observed with 20 wt % water content, but\nthe monomeric sequence effect is significantly reduced with 40 wt % water\ncontent and disappears with 80 wt % water content.\u0026nbsp; This is because the hydrophilic guest\nmolecules are more likely to be associated with water molecules than with the\npolymer network at the high water content.\u0026nbsp;\nBy analyzing the mean square displacement, the displacement of the guest\nmolecules and the inner surface area, it is also found that the guest molecule\nis confined in the system at 20 wt % water content, resulting in highly\nanomalous subdiffusion.\u0026nbsp; Therefore, the\ndiffusion of the guest molecules is directly affected by their interaction with\nthe monomer units, the monomeric sequence and the geometrical confinement in\nthe hydrogel at a low water content, but the monomeric sequence effect and the\nrestriction on the diffusion of the guest molecule are significantly decreased\nwith increasing the water content.\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\n\n\u003Cp\u003EWe also investigated the de-swelling mechanisms of the\nsurface-grafted\u003C\/p\u003E\n\n\u003Cp\u003Epoly(N-isopropylacrylamide) (P(NIPAAm)) brushes\ncontaining 1300 water molecules at 275 K, 290 K, 320 K, 345 K, and 370 K.\u0026nbsp; We clearly observed the de-swelling of the\nwater molecules for P(NIPAAm) above the lower critical solution temperature\n(LCST) (~305 K).\u0026nbsp; Below the LCST, we did\nnot observe the de-swelling of water molecules.\u0026nbsp;\nUsing the upper critical solution temperature (UCST) systems\n(poly(acrylamide) brushes) for comparison purposes, we did not observe the\nde-swelling of water molecules at a given range of temperatures.\u0026nbsp; By analyzing the pair correlation functions\nand the coordination numbers, the de-swelling of the water molecules occurred\ndistinctly around the isopropyl group of the P(NIPAAm) brush above the LCST\nbecause C(NIPAAm) does not offer sufficient interaction with the water\nmolecules via the hydrogen bonding type of secondary interaction.\u0026nbsp;

This thesis research was largely motivated by the potential quantum computing applications for fullerenes encapsulating spin-active atoms.

One way to improve fuel efficiency is to reduce the overall automobile weight. Weight reductions using steel components are desirable because of easy integration into existing manufacturing systems. Designing components with Advanced High Strength Steels (AHSS) has allowed for material reductions, while maintaining strength requirements. Two Advanced High Strength steel microstructures investigated in this research utilize different strengthening mechanisms to obtain a desired tensile strength grade of 590MPa. One steel, HR590, utilizes precipitation strengthening to refine the grain size and harden the steel. The other steel, HR590DP, utilizes a dual phase microstructure consisting of martensite constituents in a ferrite matrix. The steels are processed to have the same tensile strength grade, but exhibit different fatigue behavior. The central objective of this research is to characterize and compare the fatigue behavior of these two steels. The results show the dual phase steel work hardens at a low fatigue life. The precipitation strengthened microstructure shows hardening at low strain amplitudes, softening at intermediate strain amplitudes and little to no effect at high strain amplitudes.

Nanocrystalline materials are of particular interest\ndue to their improved mechanical properties and alternative strain\naccommodation processes at the nanoscale. These processes, or deformation\nmechanisms, within nanocrystalline materials are strongly dictated by the\nlarger volume fraction of grain boundaries and interfaces due to smaller\naverage grain sizes. The behavior of grain boundaries within nanocrystalline\nmaterials is still largely unknown. One reason is that experimental\ninvestigation at this scale is often difficult, time consuming, expensive, or\nimpossible with current resources. Atomistic simulations have shown the\npotential to probe fundamental behavior at these length scales and provide\nvital insight into material mechanisms. Therefore, we utilize atomistic\nsimulations to explore structure-property relationships of face-centered-cubic\n(fcc) grain boundaries, and investigate the deformation of nanocrystalline\ncopper as a function of average grain size.\u003C\/p\u003E\n\n\u003Cp\u003EMolecular statics employing an embedded atom method\npotential are utilized in this research to construct fcc bicrystalline grain\nboundary structures.\u003C\/p\u003E\n\n\u003Cp\u003EThe boundaries are then deformed at 10K under uniaxial\ntension and simple shear at a constant strain rate to elucidate the influence\nof interfacial structure on inelastic deformation. An algorithm is also\npresented to compute interfacial free volume in the bicrystalline structures\nand quantitatively track its evolution with imposed strain. Representative\nnon-equilibrium grain boundaries are instantiated using excess free volume as a\nmeasure of the degree of non-equilibrium state, and then deformed to explore\nthe influence of structure on deformation response.

Inelastic\ndeformation mechanisms common to nanocrystalline metals, such as heterogeneous\ndislocation nucleation, grain boundary sliding, and grain boundary migration\nare analyzed with the proposed metrics using bicrystalline grain boundaries.\nThe results indicate that unique deformation fields are associated with each\nmechanism and a sense of the deformation history of the atomic fields are\nprovided through the utilization of neighbor lists from the reference\nconfiguration.

Grain boundaries are\nobserved to be influential in smaller grained structures, while dislocation\nglide is more influential as grain size increases. Under compression, however,\nthe resolved compressive normal stress on interfaces hinders grain boundary\nplasticity, leading to a tension-compression asymmetry in the strength of\nnanocrystalline copper.

Among all types of fuel cells, solid oxide fuel cells (SOFCs) offer\ngreat promise for the most efficient and cost-effective utilization of a wide\nvariety of fuels such as hydrocarbons, coal gas and gasified biomass. The\ncritical technical barrier to fuel flexibility is the vulnerability of the\nstate-of-the-art Ni-YSZ (yttria-stabilized-zirconia) anode materials to coking\nand sulfur poisoning. In addition, the high operating temperatures of SOFCs,\nstemming from the low ionic conductivity of the electrolyte materials and the\npoor performance of the cathode materials at lower temperatures, increase costs\nand reduce the system operation life. Therefore, the main objective of the\nresearch is to develop new electrolyte and electrode materials with high\nelectrical conductivity and electrocatalytic activity at low temperatures and\nto gain fundamental understanding of the interrelationships between lattice\nstructure, local atomic environment, bulk transport, surface property and\nelectrocatalytic activity. \u003C\/p\u003E\n\n\u003Cp\u003EFour research\nthrusts will be detailed in this presentation. First, a new electrolyte was\nshown to have the highest ionic conductivity below 750\u003Csup\u003Eo\u003C\/sup\u003EC of all\nknown electrolyte materials for SOFCs applications. Synchrotron-based X-ray\ndiffraction and Extended X-ray Absorption Fine Structure (EXAFS) were employed\nto investigate the lattice structure and local atomic environment. Second, when\nused in combination with Ni as a composite anode, it was shown to provide\nexcellent tolerance to carbon buildup (coking) and deactivation (poisoning) by\ncontaminants commonly encountered in readily available fuels. The mechanism\nresponsible for the enhanced electrocatalytic activity was unraveled by\nanalyzing the anode surfaces using Raman spectroscopy and Scanning Auger\nNanoprobe. Third, a simple, cheap surface modification of state-of-the-art\nNi-YSZ anode was developed that could be more readily adopted in the latest\nfuel cell systems, demonstrating direct utilization of hydrocarbons, CO and\ngasified carbon fuels. Advanced electron microscopy and spectroscopy, Raman\nspectroscopy and Density functional theory (DFT) calculations were used to\nunderstand the anodic reactions occurring on nano-islands and nanostructured\nmetal\/oxide interface. Last, a new composite cathode with simultaneous transport\nof proton, oxygen vacancies and electronic defects was developed for\nlow-temperature SOFCs based on oxide proton conductors. \u003C\/p\u003E\n\n\u003Cp\u003EIn conclusion,\nthis report represents a critical step toward an economically feasible fuel\ncell for utilization of a wide variety of readily available fuels as well as a\nunique mechanistic investigation of structure-property relationship and\nsurface- and interfaces-involved chemical and electrochemical reactions.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMSE Ph.D. Thesis Defense \u2013 Lei Yang\u003C\/p\u003E\u003Cp\u003EThesis\nTitle: New Materials for Intermediate-temperature Solid Oxide Fuel Cells to be Powered\nby Carbon- and Sulfur- Containing Fuels\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"MSE Ph.D. Thesis Defense \u2013 Lei Yang"}],"uid":"27388","created_gmt":"2011-03-15 10:53:03","changed_gmt":"2016-10-08 01:54:22","author":"Bill Miller","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-03-18T12:00:00-04:00","event_time_end":"2011-03-18T15:00:00-04:00","event_time_end_last":"2011-03-18T15:00:00-04:00","gmt_time_start":"2011-03-18 16:00:00","gmt_time_end":"2011-03-18 19:00:00","gmt_time_end_last":"2011-03-18 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1238","name":"School of Materials Science and Engineering"}],"categories":[],"keywords":[{"id":"10802","name":"MSE_Interal_Event"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"64366":{"#nid":"64366","#data":{"type":"event","title":"MSE Spring Open House","body":[{"value":"\u003Cp\u003EMSE Spring Open House\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMSE Spring Open House\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"MSE Spring Open House"}],"uid":"27388","created_gmt":"2011-02-21 09:46:05","changed_gmt":"2016-10-08 01:54:14","author":"Bill Miller","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-03-12T08:30:00-05:00","event_time_end":"2011-03-12T13:00:00-05:00","event_time_end_last":"2011-03-12T13:00:00-05:00","gmt_time_start":"2011-03-12 13:30:00","gmt_time_end":"2011-03-12 18:00:00","gmt_time_end_last":"2011-03-12 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1238","name":"School of Materials Science and Engineering"}],"categories":[],"keywords":[{"id":"10802","name":"MSE_Interal_Event"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"64317":{"#nid":"64317","#data":{"type":"event","title":"MSE Ph.D. Proposal - Maeling Tapp","body":[{"value":"\u003Cp\u003ETitle: In Vitro Selection of DNA Aptamers for Gold\nNanoparticles\u003C\/p\u003E\n\n\n\n\u003Cp\u003ESummary: \u003C\/p\u003E\u003Cp\u003EAptamers are\nsingle-stranded oligonucleotide sequences that exhibit high affinity and high\nspecificity binding for nonnucleotide targets.\u003C\/p\u003E\n\n\u003Cp\u003EUsing a procedure called \u0022systematic evolution of\nligands by exponential enrichment\u0022 (SELEX), aptamers can be identified\nfrom combinatorial libraries consisting of ~ 1012-1015 random sequences.

The high hardness, high elastic modulus and low\ndensity of B4C make it a nearly ideal material for personnel and vehicular\narmor. B4C plates formed via hot-pressing are currently issued to U.S. soldiers\nand have exhibited excellent performance; however, hot-pressed articles contain\ninherent processing defects and are limited to simple geometries such as\nlow-curvature plates.\u003C\/p\u003E\n\n\u003Cp\u003ERecent advances in the pressureless sintering of B4C have\nproduced\u003C\/p\u003E\n\n\u003Cp\u003Etheoretically- dense and complex-shape articles that also\nexhibit superior ballistic performance.\u003C\/p\u003E\n\n\u003Cp\u003EHowever, the cost of this material is currently high due\nto the powder shape, size, and size distribution that are required, which\nlimits the economic feasibility of producing such a product. Additionally, the\nlow fracture toughness of pure boron carbide may have resulted in historically\nlower transition velocities (the projectile velocity range at which armor\nbegins to fail) than competing silicon carbide ceramics in high-velocity\nlong-rod tungsten penetrator tests. Lower fracture toughness also limits\nmulti-hit pro- tection capability. Consequently, these requirements motivated\nresearch into methods for improving the densification and fracture toughness of\ninexpensive boron carbide composites that could result in the development of a\nsuperior armor material that would also be cost-competitive with other\nhigh-performance ceramics.\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp; The primary\nobjective of this research was to study the effect of titanium and car- bon\nadditives on the sintering and mechanical properties of inexpensive B4C\npowders.\u003C\/p\u003E\n\n\u003Cp\u003EThe boron carbide powder examined in this study was a\nsub-micron (0.6 \u03bcm median particle size) boron carbide powder produced by H.C.\nStarck GmbH via a jet milling process. A carbon source in the form of phenolic\nresin, and titanium additives in the form of 32 nm and 0.9 \u03bcm TiO2 powders were\nselected. Parametric studies of sinter- ing behavior were performed via\nhigh-temperature dilatometry in order to measure the in-situ sample contraction\nand thereby measure the influence of the additives and their amounts on the\noverall densification rate. Additionally, broad composition and\nsintering\/post-HIPing studies followed by characterization and mechanical\ntesting elucidated the effects of these additives on sample densification,\nmicrostructure de- velopment, and mechanical properties such as Vickers\nhardness and microindentation fracture toughness.\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp; Based upon this\nresearch, a process has been developed for the sintering of boron carbide that\nyielded end products with high relative densities (i.e., 100%, or theo- retical\ndensity), microstructures with a fine (2-3\u003C\/p\u003E\n\n\u003Cp\u003E\u03bcm) grain size, and high Vickers microindentation\nhardness values. In addition to possessing these improved physical properties,\nthe costs of producing this material were substantially lower (by a factor of 5\nor\u003C\/p\u003E\n\n\u003Cp\u003Emore) than recently patented work on the pressureless\nsintering and post- HIPing of phase-pure boron carbide powder.

Upon\nheating to high temperatures, these additives produced fine-scale TiB2 and\ngraphite inclusions that served to hinder grain growth and substantially\nimprove overall sintered and post-HIPed densities when added in sufficient\nconcentrations.\u003C\/p\u003E\n\n\u003Cp\u003EThe fine boron carbide grain size manifested as a result\nof these second phase inclu- sions caused a substantial increase in hardness;\nthe highest hardness specimen yielded a hardness value (2884.5 kg\/mm^2)\napproaching that of phase-pure and theoretically- dense boron carbide (2939 kg\/mm^2).\u003C\/p\u003E\n\n\u003Cp\u003EAdditionally, the same high-hardness composi- tion\nexhibited a noticeably higher fracture toughness (3.04 MPa\u00b7m^1\/2) compared to\nphase-pure boron carbide (2.42 MPa\u00b7m^1\/2), representing a 25.6% improvement.

Metallurgical\ninterconnections have evolved from the conventional eutectic and lead-free\nsolders to fine pitch copper pillars with lead-free solder cap. However,\nscaling down the bump pitch below 50-80\u00b5m and increasing the interconnect\ndensity with this approach creates a challenge in terms of accurate solder mask\nlithography and joint reliability with low stand-off heights. Going beyond the\nstate of the art flip-chip interconnection technology to achieve ultra-fine\nbump pitch and high reliability requires a fundamentally- different approach\ntowards highly functional and integrated systems. This research demonstrates a\nlow-profile copper-to-copper interconnect material and process approach with\nless than 20\u00b5m total height using adhesive bonding at lower temperature than\nother state-of-the-art methods. The research focuses on: (1) exploring a novel\nsolution for ultra-fine pitch (\u0026lt; 30\u00b5m) interconnections, (2) advanced\nmaterials and assembly process for copper-to-copper interconnections, and (3)\ndesign, fabrication and characterization of test vehicles for reliability and\nfailure analysis of the interconnection. \u003C\/p\u003E\n\n\u003Cp\u003EThis research represents the first demonstration of\nultra-fine pitch Cu-to-Cu interconnection below 200\u00b0C using non-conductive film\n(NCF) as an adhesive to achieve bonding between silicon die and organic\nsubstrate.

The\ntest vehicles were studied for mechanical reliability performance under\nunbiased highly accelerated stress test (U-HAST), high temperature storage\n(HTS) and thermal shock test (TST). This robust interconnect scheme was also\nshown to perform well with different die sizes, die thicknesses and with\nembedded dies. A simple and reliable, low-cost and low-temperature direct Cu-Cu\nbonding was demonstrated offering a potential solution for future flip chip\npackages as well as with chip-last embedded active devices in organic\nsubstrates.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThesis Title: Chip-Last Embedded Low Temperature\nInterconnections With Chip-First Dimensions\u003C\/p\u003E\u003Cp\u003ETime: 1:30 PM, Tuesday 8th November\u003C\/p\u003E\n\n\u003Cp\u003ELocation: MaRC 351\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"MSE M.S.

By softening and\ncrystallizing a supercooled polymer at the same temperature, the embossing and\nsolidification stages can be carried out isothermally without thermal cycling.\nThe new process was demonstrated for replicating rectangular trenches with\ndifferent aspect ratio for two different polymers PET and PEEK.The raw\nmaterials were characterized for their thermal and rheological properties to\ndetermine the processing parameters. The polymers were also characterized by a\nmodified tensile testing apparatus to determine the tensile properties of the\nfilm during embossing. The processing parameters including embossing\ntemperature, embossing pressure and embossing time were varied based on the\nmaterial properties and optimized. A semi-empirical model was established to\ncorrelate the crystallizing kinetics of the materials to the change in\nrheological properties during embossing. The model was used as a tool to\npredict the rheological properties of the polymer at conditions where\nexperimental determination is difficult.Finally, embossing simulations with the\nsemi-empirical rheological model were conducted to study the unique process\ndynamics of constant-temperature embossing and verify some experimental\nfindings. Different cases of constant-temperature embossing involving low to\nhigh rates of crystallization were simulated and compared with the conventional\nembossing process.

The search for replacement body parts has fuelled the highly interdisciplinary field of tissue engineering and regenerative medicine. In view of the challenges in this field, one must consider that the human embryo in its first eight weeks of life undergoes an extraordinary transformation from a single cell to a 3-cm-long fetus with a beating heart, gut, nervous system, and limbs with fingers and toes. This progression involves massive growth, physical folds and twists, and myriad cellular and molecular events of breathtaking complexity; yet it is the ultimate goal of this field of tissue engineering to recreate some of these processes in microcosm, to replace and regenerate lost tissue. At last the field has entered a period of fruition, and seems set to realize its potential to treat a multitude of debilitating and deadly conditions such as myocardial infarction, spinal injury, osteoarthritis, osteoporosis, diabetes, liver cirrhosis and retinopathy. \u003C\/p\u003E\u003Cp\u003EThis talk will outline progresses in the field and how we are developing new bioactive materials that can be implanted into the body and provide the right environmental cues that promote tissue regeneration of large volumes of highly organized tissue such as bone.

One of the key challenges for\nthe future use of bioethanol is to increase its availability in the market via\nan efficient and economic way. However, one major concern in using the existing\ngas-pipelines to transport fuel-grade ethanol or blended fuel is the potential\ncorrosion and stress corrosion cracking (SCC) susceptibility of carbon steel\npipelines in these environments. In this talk, both phenomenological and\nmechanistic investigations have been carried out in order to address the\npossible degradation phenomena of X-65 pipeline carbon steel in simulated\nfuel-grade ethanol (SFGE). Firstly, the susceptibilities of stress corrosion\ncracking of this steel in SFGE were studied. Ethanol chemistry of SFGE was\nshown to have great impact on the stress corrosion crack initiation\/propagation\nand the corrosion mode transition. Inclusions in the steel can increase local\nplastic strain and act as crack initiation sites. Secondly, the anodic behavior\nof carbon steel electrode was investigated in detail under different ethanol\nchemistry conditions. General corrosion and pitting susceptibility under\nunstressed condition were found to be sensitive to the ethanol chemistry.\u003C\/p\u003E\n\n\u003Cp\u003ELow tendency to passivate and the sensitivity to ethanol\nchemistry are the major reasons which drive corrosion process in this system.\nOxygen plays a critical role in controlling the passivity of carbon steel in ethanol.\u003C\/p\u003E\n\n\u003Cp\u003EThirdly, the detailed study was carried out to understand\nthe SCC mechanism of carbon steel in SFGE. A film related anodic dissolution\nprocess was identified to be a major driving force during the crack\npropagation.

It is the structure that\ngives the metal foams the characteristics that make them well suited for many\napplication including heat exchangers. In this work, the structure of open\ncelled metal foams is quantitatively characterized using an image analysis\nbased method in order to predict the evaporative heat transfer of the metal\nfoam using the fluid permeability. Several image processing algorithms were\ndeveloped to quantitatively characterize the porosity, surface area per unit\nvolume and the tortousity of metal foams from digital images of the cross\nsections of the material, and an expression was used to calculate the fluid\npermeability. An algorithm was developed to partion the pore space in the\ndigital images so that individual cells within the structure\u0026nbsp; could also be quantitatively\ncharacterized.\u0026nbsp; Tools were also developed\nto predict the structure of open celled foam processed using the sacrificial\ntemplate method by digitally constructing microstructures based the particle\npacking of the sacrificial templating material.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"MSE MS Defense - Stephanie Lin"}],"uid":"27388","created_gmt":"2010-10-26 07:50:58","changed_gmt":"2016-10-08 01:53:16","author":"Bill Miller","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-11-03T12:00:00-04:00","event_time_end":"2010-11-03T13:00:00-04:00","event_time_end_last":"2010-11-03T13:00:00-04:00","gmt_time_start":"2010-11-03 16:00:00","gmt_time_end":"2010-11-03 17:00:00","gmt_time_end_last":"2010-11-03 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1238","name":"School of Materials Science and Engineering"}],"categories":[],"keywords":[{"id":"10802","name":"MSE_Interal_Event"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"61330":{"#nid":"61330","#data":{"type":"event","title":"MSE Ph.D. Defense for David Safranski","body":[{"value":"Title:Poly(\u00df-amino esters)for Cardiovascular Applications.\n                                     safranski@gatech.edu \n                                       Love Room 3201A, 9:00am.
