| 报告介绍 | 报告摘要：
Metal nanostructures promise to address needs in catalysis, nanomedicine, chemical sensing and more, with the physical and chemical properties of metal nanocrystals determined by a set of structural parameters that include their size, shape, composition, and architecture. Eloquent examples of metal nanostructures prepared by colloidal methods exist. However, fundamental questions about the transformations from metal precursor to metal nanostructure remain and the rational synthesis of new nanostructures is often elusive. Inspired by principles of coordination chemistry, guidelines for the synthesis of structurally defined monometallic and bimetallic nanostructures based on precursor selection will be outlined. These guidelines are supported by in-situ studies of nanostructure formation via synchrotron scattering techniques, where the local ligand environment of metal precursors was found to influence nanostructure growth rates and in turn nanostructure morphology. These advances in synthesis offer the strategies necessary to achieve new nanostructures designed for specific function, and this presentation will conclude with examples in which advanced nanomaterial synthesis provides new nanoscale platforms for catalysis. 个人简介： Dr. Sara E. Skrabalak received her B.A. degree in chemistry from Washington University in St. Louis in 2002 where she conducted research with Professor William E. Buhro. She completed her Ph.D. degree in chemistry from the University of Illinois at Urbana-Champaign in fall of 2006 under the tutelage of Professor Kenneth S. Suslick. She then conducted postdoctoral research at the University of Washington – Seattle with Professors Younan Xia and Xingde Li. She is an Associate Professor of Chemistry at Indiana University – Bloomington and a recipient of both an NSF CAREER Award and DOE Early Career Award. She is a 2012 Research Corporation Cottrell Scholar, a 2013 Sloan Research Fellow, and 2014 Camille Dreyfus Teacher-Scholar. She is the recipient of the 2014 ACS Award in Pure Chemistry. This award is sponsored by Alpha Chi Sigma and recognizes young scholars who have “accomplished research of unusual merit for an individual on the threshold of her or his career” in pure chemistry. Her research group focuses on nanomaterial design and synthesis (http://www.indiana.edu/~skrablab/). |
