Several recent studies on uranyl reduction suggest that this process occurs in a step-wise fashion, transiently generating the unstable pentavalent uranyl ion (UO\u003Csub\u003E2\u003C\/sub\u003E\u003Csup\u003E+\u003C\/sup\u003E).  Our laboratory is exploring the synthesis and reactivity of pentavalent uranyl, in particular the reactivity of its two oxo ligands, in an attempt to model the microbial reduction of UO\u003Csub\u003E2\u003C\/sub\u003E\u003Csup\u003E2+\u003C\/sup\u003E.  We are also exploring the stability of the U(VI) and U(V) oxidation states, as a function of ligand environment, and we have synthesized a series of uranium alkoxide, amide and alkyl complexes to support these efforts. \n\u003C\/p\u003E\n\u003Cp\u003EInorganic Divisional Seminar\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:jake.soper@chemistry.gatech.edu\u0022\u003EProf. Jake Soper\u003C\/a\u003E (404-894-4022).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Trevor Hayton, University of California-Santa Barbara\n\nOxo ligand functionalization in the uranyl ion\n\nInorganic Divisional Seminar","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Trevor Hayton, University of California-Santa Barbara"}],"uid":"27275","created_gmt":"2009-07-21 00:00:00","changed_gmt":"2016-10-08 01:47:17","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-02-03T14:00:00-05:00","event_time_end":"2010-02-03T15:00:00-05:00","event_time_end_last":"2010-02-03T15:00:00-05:00","gmt_time_start":"2010-02-03 19:00:00","gmt_time_end":"2010-02-03 20:00:00","gmt_time_end_last":"2010-02-03 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.science.ucsb.edu\/faculty\/profile\/266","title":"Prof. Trevor Hayton, UC Santa Barbara"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"89","name":"chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
