报告摘要：
Covalent chemistry presumably occurs randomly on the graphene lattice of a single-walled carbon nanotube because electrons are delocalized over thousands of atomic sites. A small number of random defects, however, can completely destroy the remarkable electrical and optical properties of these atom-thick materials. In this talk I will discuss two projects focused on learning (1) where and how does a molecule covalently bond to the “pi-electron sea?” (2) how does surface chemistry affect the electrical and optical properties of a carbon nanotube? Will an inner tube within a covalently functionalized double-wall nanotube behaves like a single-walled carbon nanotube?

Prof. Yuhuang Wang obtained his PhD in 2005 from Rice University (supervisor: Richard Smalley, Nobel Laureate in Chemistry). He then joined Northwestern University as a postdoctoral associate (advisor: Chad A. Mirkin). Since August 2008 he has been an Assistant Professor of Department of Chemistry and Biochemistry, University of Maryland (http://www2.chem.umd.edu/groups/wang).
Prof. Yuhuang Wang has several fields of interest, including Ultra-selective Carbon Network Chemistry, Nanoelectrode Networks for Energy Storage and Harvesting, “Seeded Crystalization” of Nanostructures: From Discrete Nanoparticles to Organized Solids. He published 47 international journal articles including Nature Commun., JACS (>2,115 citations) and holds 5 issued and 4 licensed patents. He was the member of National Science Foundation review panels (2010) and served as the Symposium Organizer of 237th ACS meeting. He is the recipients of NSF CAREER Award (2011), ACS Petroleum Research Fund Doctoral New Investigator (2010), Rice Alumni Spotlight, Wiess School of Natural Sciences, Rice University (2010).
