Materials Science Program Seminar

THE MORK FAMILY DEPARTMENT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCE PRESENTS A SEMINAR
BYPhilippe MarcusLaboratoire de Physico-Chimie des Surfaces
CNRS-ENSCP (UMR 7045)Nanostructure and reactivity of ultra-thin oxide films on metal
and alloy surfacesAbstractThe growth mechanisms, the structure and the stability of oxide films produced electrochemically on metal and alloy surfaces (Cu, Ni, Cr, and stainless steels) will be presented, with emphasis on high resolution data obtained by in situ Scanning Tunnelling Microscopy, combined with ex situ X-ray Photoelectron Spectroscopy. The surface hydroxylation of oxides, the crystallinity, and the role of defects in the stability of passive films will be examined. The results of recent DFT calculations on the interaction of Cl- with hydroxylated nickel oxide surfaces will be presented, and the experimental and theoretical data will be compared.October 19, 2005
