Campus Map
The research at the Laboratory for MicroMechanics of Materials is concentrated on design, controlled fabrication/characterization and modeling of materials (including composites, superplastic, magnetic and thin film layered structures/nanostructures) for applications in renewable/clean energy and energy conversion devices as well as biomedical and tissue engineering. The main emphasis is to investigate the effect of microstructure, morphology and processing parameters on functional properties of such materials including thermomechanical, magnetic and electronic/ionic transport properties for variety of applications, such as Solid Oxide Fuel Cells (SOFCs), Solar Cells and scaffold engineering.

     A variety of analytical approaches together with computational analysis (statistical analysis and neural network are used to characterize the distribution of the microstructure and its linkage to these properties. One major emphasis is to apply the concept of n-point probability functions to composites (elastic, plastic and magnetic materials) and finally to polycrystalline materials and layered structures at the nanoscale for the design and comprehensive understanding of the microstructure-property-performance relationship in composite micro/nanostructures for next generation devices.
