Novel Synthesis of Nanocrystals test test test One focus of MRSEC research is in developing novel ways of making nanocrystals, particularly metal oxide nanocrystals. We are pursuing new ways of synthesizing different types of particles by colloidal methods, such as iron oxide nanoparticles (gamma-Fe2O3, TEM figure 1) and HfZrO2 nanoparticles and nanorods (figure 2). We are also investigating the synthesis of CeO2-y and ternary nanocrystals such as CeZrO2 by room temperature liquid phase methods, and of vanadium oxide nanorwires by hydrothermal methods (figure 3). The synthesis of iron oxide nanocrystals was a collaboration with Chris Murray of the IBM T.J.
Watson Research Center (currently at the University of Pennsylvania).
The TEM in figure 2 is the result of a collaboration with Yimei Zhu at Brookhaven National Laboratory.
