In situ & Ex situ Characterization of Nanocrystals Suneel Kodambaka, Department of Materials Science and Engineering, University of California Los Angeles, Los Angeles, CA 90095 Our goals are to develop a fundamental understanding of the: (1) chemical reaction kinetics controlling the carbothermal reduction process and (2) morphological and structural evolution in nanocrystals. In situ TEM studies of carbothermal reduction reactions in C-TiO2 In situ TEM studies of microstructural evolution in Co3O4 Initial results have yielded new insights into nanocrystal synthesis and stabilities. Further investigation is required to better understand the underlying processes.
