Stability of Ceria and Other NanoParticles
EMSL Project ID
11696
Abstract
This project examines the stability of Ceria, Titania and other nanoparticles. The particles to be examined will be prepared at the University of Central Florida and those obtained commercially. Their properties will be compared to films grown at PNNL by spin coating and by MBE. One focus of the research is the stability (including effects of ion sputtering) and structure of particles at different sizes. Environmental effects and history will be examined.
