报告摘要：
This presentation will have two parts on using single-molecule approaches to study foundamental catalytic processes. In part 1, I will describe our efforts in developing and applying single-molecule super-resolution imaging approaches to study catalysis on nano/micro-scale catalyst particles, focusing on our recent work of imaging nonfluorescent surface processes. In part 2, I will describe our work in developing methods to study the polymerization catalysis of forming single polymer chains down to single-monomer resolution, leading to microscopic sequencing of single copolymer chains.
报告人简介：
Peng Chen is the Peter Debye Professor of Chemistry at Cornell University. He did his B.S. at Nanjing University, Ph.D. at Stanford University, and postdoc at Harvard University. His group pioneered the study of single-nanoparticle catalysis, electrocatalysis, and photoelectrocatalysis; of living polymerizations by single molecular catalysts; and of biological inorganic systems in vitro and in living cells; using single-molecule/particle imaging and manipulation methods. His current research interests are heterogeneous and homogeneous catalysis, bacterial metal homeostasis, and bioenergy conversion. He is a member of American Academy of Arts and Sciences and a fellow of American Association for the Advancement of Science. He has received many national and international awards and given many named, plenary, and keynote lectures.
