A bi-weekly event to present and discuss issues related to developments, applications and commercialization of nanotechnology.

Nano-scale materials present significant challenges to structural characterization. The average structure obtained with traditional x-ray diffraction methods is not a good measure of the structural details which often determine the function of a material. X-ray absorption spectroscopy provides a local probe with which to characterize the geometric and electronic structure of nano-scale systems. A brief description of x-ray absorption spectroscopy will be followed by an example of its application to the study of nanoparticle catalysts in a working fuel cell.

Bio: Professor Carlo U. Segre

Professor Segre received a B.S. in physics and a B.S. in chemistry at the University of Illinois at Urbana-Champaign in 1976. He completed his Ph.D. in physics from the University of California, San Diego in 1981 under Professors Bernd Matthias and M. Brian Maple and then spent two years as a post-doc with Prof. Mark Croft at Rutgers University in New Jersey. He has been on the IIT faculty since 1983 with a one-year sabbatical in Trieste, Italy at the International Centre for Theoretical Physics. He has over 90 refereed publications.
Professor Segre's research centers around the structure and electronic properties of complex materials including superconducting, magnetic and catalytic materials primarily using x-ray diffraction and x-ray absorption spectroscopy. He also serves as Deputy Director of the Materials Research Collaborative Access Team (MRCAT) which operates an experimental facility for materials research at the Advanced Photon Source (APS).
