Research in this group is limited by Dr. Cussler's retirement. The remaining topics center on coupled diffusion and chemical reaction. At present, the key topics are crystallization enhanced by high pressure, ammonia production by coupled absorption and catalytic reaction, and the purification of organic light emitting diodes by sublimation. The studies of crystallization aid purification of non-volatile moderate molecular weight molecules, including some drugs and agrochemicals. The production of ammonia tries to build a small ammonia plant which is powered by wind. The sublimation studies, a key to the low cost production of flat screen televisions, involve three types of transport: conventional diffusion, Knudsen diffusion, and molecular velocity. All topics are anchored within chemical engineering.
