Abstract:

The instrumentation acquired from this grant consists of two atomic force microscopes from Park Scientific and Molecular Imaging and a particle size analyzer from Micromeritics. The atomic force microscopes are complementary in terms of their operation and use the same controller and software. The Park Scientific instrument has been used to characterize the microstructure development of thin films of the oxygen ion conductor, BICUVOX Bi2V0.9Cu0.1O5.35 over the temperature range from 550 to 800 deg C. Grain growth occurring in the film appears to he two-dimensional in nature. The Molecular Imaging AFM is designed for characterizing the topology of liquidsolid interfaces. This instrument has been used to image the surface of a lithium battery cathode material, V2O5, during lithium intercalation. The particle size analyzer has been used to characterize the particle size and particle size distribution of powders of various materials produced by the Pechini method as a function of heat treatment temperature.
