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.
