摘要:Colloidal inorganic nanostructures have been in the focus of research interest for over three decades due to their unique chemical and physical properties that can be tuned by controlling their size, shape, surface, and special arrangement. From the point of view of synthesis, colloidal inorganic nanostructures are similar to artificial macromolecules in that they can be produced by joining monomer units together to form large ensembles through direct molecular reactions. Inorganic nanostructures are however also quite different from macromolecules in terms of structural and morphological rigidity, the nature of internal and surface bonds, and the surface reactivity, which enable many unconventional and indirect routes to these materials, and often produce nanostructures with forms that are difficult to obtain through conventional methods such as simple precipitation processes. For example, templating method uses a pre-existing guide with desired nanoscale features to direct the formation of nanostructures with unique crystal structures, morphologies and properties. In this talk, I will discuss a number of unconventional routes toward controlled nanostructure synthesis, including seeded growth and its combination with soft and hard templates for growing metal nanocrystals, and the use of nanoscale Kirkendall effect or other conversion chemistry for the creation of metal or compound nanostructures.  

主讲嘉宾简介:

    Prof. Yadong Yin received his B.S. (1996) and M.S. (1998) in Chemistry from the University of Science and Technology of China (with Prof. Zhicheng Zhang), and PhD (2002) from the University of Washington, Seattle (with Prof. Younan Xia).  In 2003 he became a postdoctoral fellow at the University of California, Berkeley under the supervision of Prof. A. Paul Alivisatos, and then a staff scientist at Lawrence Berkeley National Laboratory in 2005. He joined the faculty at the Department of Chemistry, University of California, Riverside as an Assistant Professor in 2006, and then he was promoted to Full Professor in 2014.  His research interest focuses on the synthesis, self-assembly, and functionalization of nanostructured materials for catalytic, analytical, and photonic applications.  His recent recognitions include Cottrell Scholar Award (2009), DuPont Young Professor Grant (2010), 3M Nontenured Faculty Grant (2010), NSF CAREER award (2010), and NML Researcher Award (2016).  He was ranked by Thomson Reuters among the Top 100 Chemists and Top 100 Materials Scientists in the world in the period of 2000-2010, as well as the Highly Cited Researcher in Chemistry (2014-2016) and Materials Science (2014), based on the citation impact. He is currently an associate editor of the Journal of Materials Chemistry C, and also serves on the editorial board for NPG Asia Materials, Advanced Functional Materials, SCIENCE CHINA Materials, and ChemNanoMat.
