Bio: David Y.H. Pui is a Regents Professor at the University of Minnesota. He is a Member of the U.S. National Academy of Engineering and an academician of Academia Sinica (Taiwan, China). Dr. Pui is the Director of the Center for Filtration Research consisting of 18 international filtration manufacturers. He has a broad range of research experience in aerosol/nanoparticle engineering and filtration technology and has over 370 journal papers and 42 patents. He has developed several widely used commercial aerosol instruments for PM2.5 measurements and large-scale urban air cleaning systems. He received the Max Planck Research Award (1993), the CAS Einstein Professor Award (2013), and the Fuchs Memorial Award (2010) - the highest d
isciplinary award conferred jointly by the American, German and Japanese Aerosol Associations. He served as President of the American Association for Aerosol Research (2000-2001), and President of the International Aerosol Research Assembly (2006-2010) consisting of 16 national associations from around the world.
Abstract: Under the Center for Filtration Research (CFR) with 18 international filtration company sponsors, we are developing green technologies to benefit clean and sustainable environment, which will enable people and the environment to prosper together. I will first review our research in toxicity study of carbon nanotubes and exposure study in a pilot nanoparticle production plant, leading to the development of a Nanoparticle Surface Area Monitor (NSAM). The development of the US EPA PM2.5 standard will also be reviewed showing the adverse health effects of the sub-2.5 particles. CFR investigators perform fundamental and applied research on air, gas and liquid filtration. The current research projects include indoor air cleaning and Covid prevention, bioaerosols sensor development and evaluation, and effects of wildfires loading on the performance of respirator and HVAC filters. Large-scale air cleaning towers are established in Xi’an and Yancheng in China, and two additional towers in Delhi, India. They are developed to mitigate PM2.5 pollutants in urban air. The second-generation tower can also reduce CO2 in the atmosphere. All these research and development activities are helping to improve clean and sustainable environment.
