Fall Chem501 Seminar

UT Host:  Dr. Sharani Roy

Speaker: Dr. George Schatz

Robert L. Letsinger Professor of Chemistry

Northwestern University

Title:  "Nanoparticles, SERS and Theory"

Abstract:  Silver and gold nanoparticles have a history that dates to the Roman empire and before, as well as detailed work by Michael Faraday in the 1850s.  However these particles have been given new life (and applications) in the last 40 years through a number of advances in nanoscience, and especially by the discovery of surface enhanced Raman spectroscopy (SERS) in the 1970s. This talk will provide an overview of these advances, especially as relates to SERS substrates, to single-molecule SERS, to tip enhanced Raman spectroscopy (TERS), and to plasmon-driven chemistry.  An emphasis in this talk will be on the use of theory to understand the optical properties of plasmonic materials, including both electronic structure theory and electromagnetics.

Bio:  George C. Schatz is Charles E. and Emma H. Morrison Professor of Chemistry at Northwestern University.  He received his undergraduate degree in chemistry at Clarkson University and a Ph. D at Caltech.  He was a postdoc at MIT, and has been at Northwestern since 1976.   Schatz is a theoretician who studies the optical, structural and thermal properties of nanomaterials, including plasmonic nanoparticles, plasmonic metamaterials, DNA and peptide nanostructures, and carbon-based materials. He has contributed to theories of dynamical processes, including gas phase and gas/surface reactions, energy transfer processes, transport phenomena and photochemistry. Schatz has published four books and over 1000 papers. Schatz is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and he has been Editor-in-Chief of the Journal of Physical Chemistry since 2005.   He has received numerous awards, including the Debye Award of the ACS, the S F Boys-A Rahman Award of the Royal Society of Chemistry, and the Langmuir Award of the ACS.  He is a Fellow of the American Physical Society, the Royal Society of Chemistry, the American Chemical Society and of the AAAS.
