development of effective
characterization techniques is crucial for fundamental
studies and for improving
analytic tools. In particular, pore-scale and particle-scale
characterization is at the heart of establishing links
between microscale structure and bulk properties in
granular and porous materials.
The links on the left provide a brief overview of
current areas of research. New tools are being developed
for quantifying structure, spatial correlation, ordering,
and stability, in both real and computer-generated
materials. In turn, these tools are used to help understand processes such as flow maldistribution in chemical reactors, gas diffusion in
fuel-cell membranes, improved methods for oil recovery,
and fluid injection in high-performance materials.
