at the Laboratory for MicroMechanics of Materials is concentrated on
and modeling of materials (including composites, superplastic, magnetic
film layered structures/nanostructures) for applications in renewable/clean
energy and energy conversion
devices as well as biomedical and tissue engineering. The main emphasis
investigate the effect of microstructure, morphology and processing
parameters on functional properties of such materials including
magnetic and electronic/ionic transport properties for variety of
such as Solid Oxide Fuel Cells (SOFCs), Solar Cells and scaffold
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.
Congratulations to Eric Hoar for his receipt of the NSF Graduate Research Fellowship!
