Biomolecules, Nanostructures and Interfaces - Time Resolved Vibrational Spectroscopy of Materials and Material Transformations

Abstract

In this talk I will discuss novel techniques of ultrafast laser vibrational spectroscopy and their applications to materials and material transformations. These techniques provide detailed pictures of molecular dynamics with the kind of ultrahigh time and space resolution that has previously been available only in computer simulations. Illustrative examples will be presented including: combustion of energetic materials containing nanoparticles, structural fluctuations at the active sites of proteins, energy transduction in molecular nanostructures and interfaces, and electrochemical processes at nanostructured fuel cell electrodes.

Bio: Dana D. Dlott received a B.A. degree from Columbia University in 1974 and a Ph.D. from Stanford University in 1979 under the supervision of Prof. Michael D. Fayer. In 1979 he joined the faculty at the University of Illinois. Dlott is an experimental physical chemist known for his novel applications of ultrafast nonlinear coherent spectroscopic methods to condensed phase dynamics. Current research in his laboratory includes studies of nanomaterials, molecular and biomolecular materials, shock compression science, fundamental mechanisms of energetic materials including nanotechnology materials, dynamics of surfaces and interfaces, electrochemical surface science, and applications of lasers in imaging science. He is an Alfred P. Sloan Fellow and a Fellow of AAAS, APS and OSA
