Dr. Ronald S. Goeke, of Sandia National Laboratories, will deliver the Materials Engineering Department seminar. His talk is titled, "Synthesis and Thermal Stability of Au-ZnO Nano-Composite Thin Films for Electrical Contacts. ' Goeke received his Ph.D. and M.S. in Chemical Engineering from The University of New Mexico and his B.S. from New Mexico State University. He is presently a member of the Materials Science Center at Sandia National Laboratories. Current research efforts are primarily focused on the development of thin films via vapor deposition for tribological, optical and diffusion barrier applications. Noon Friday, April 4, in Cramer 124.
