Research


Our research focuses primarily on the physical behavior and processing characteristics of fine particle systems and colloidal suspensions. We are involved in the development of strategies that exploit or control the colloidal and interfacial chemistry of the system to achieve improved processing behavior and ultimately the enhanced performance of the final materials. Specifically, we are involved in the development of colloidal engineering strategies for processing of oxide solids (ceramic composites and monoliths) and in fundamental studies of dispersive mixing phenomena for filled polymer composites. Stability and the development of morphology in coatings dispersions are also being studied. In addition, wetting and spreading of liquids on fine-particles is an ongoing research interest, and novel experimental approaches to measure these effects are being developed. Recently, we have begun investigation into simulating and modeling the hydrodynamic, chemical and mechanical effects that occur in polishing processes within the microelectronics fabrication industries with the intent of pointing out process improvements. Transport phenomena occurring in dense two-phase flows are also being modeled. Finally, we have developed several methods that use resonant acoustic fields to perform sharp fine-particle separations with applications in chemical and biochemical processing.
