Responsibilities and Interests
Cation Exchange Processes: Research interests include: (1) fundamental cation exchange (kinetics, equilibria and thermodynamics) in clay minerals, zeolites and tobermorites, and (2) separations of critical and strategic metals and hazardous radioactive species.

Nuclear and Hazardous Waste Disposal: Research interests include: (1) ceramic waste from development; (2) leach testing of waste forms; and (3) immobilization of radioactive species by ion exchange.

Ultrafine particles (powders): Research interests include: (1) preparation of ultrafine powders by hydrothermal and sol-gel methods, and (2) powder characterization of size, shape, composition and surface area by using different techniques.

Sol-Gel Chemistry: Research interests include: (1) preparation of nanocomposite and single phase sol-gel bulk materials and thin films for structural and electronic applications; (2) structural investigation of sol-gels by TEM and NMR; and (3) preparation and characterization of nanocomposites of clays, gels and zeolites for use as desiccants.
