Research

Research is in the field of aerosol science and technology, including studies on nanoparticle production and measurement, micro- and nano-contamination research, filtration and separation technology, aerosol instrumentation, as well as aerosol charging, sampling, transport, and deposition mechanisms. Current research projects include: protection schemes for EUVL masks from nanoparticle contamination, nanoparticle filtration, physicochemical characteristics and toxicological properties of nanoparticles, measurement of nanoparticle surface area deposited in the lung, experimental and theoretical investigations of dust loading on air filters, behavior of fine particles in vacuum, as well as instrumentation for nanoparticles measurements and nanobiotechnology applications.

Professor Pui has approximately 250 publications on the subjects and has developed or co-developed several widely used aerosol instruments. He is a fellow of the American Society of Mechanical Engineers (ASME) and is a recipient of the Smoluchowski Award in 1992, the Max Planck Research Award in 1993, the International Aerosol Fellow Award in 1998, Humboldt Research Award for Senior U.S. Scientists in 2000 and the AAAR David Sinclair Award (2002). He served as President of the American Association for Aerosol Research (AAAR) 2000-01 and has organized several international symposia to promote research cooperation especially among young scientists.

Center for Filtration Research

The Center carries out both basic and applied research in all aspects of gas and liquid filtration. Research interests include fibrous and membrane filters for gas and liquid filtration, theory of filtration, development of advanced filter test methods, and research on advanced filter materials for improved fluid/particle separation characteristics. The research is supported by several industrial firms in the filtration industry, as well as by governmental research contracts and grants.
