讲座人 David Y.H. Pui
讲座人介绍 Professor David Y. H. Pui is a Distinguished McKnight University Professor and LM Fingerson/TSI Inc. Chair in Mechanical Engineering at the University of Minnesota.  Dr. Pui is a Member of the U.S. National Academy of Engineering (NAE) and Director of the world-renowned Particle Technology Laboratory (PTL) at the University of Minnesota.  He is also the Director of the Center for Filtration Research (CFR) with 18 leading international filtration companies as members.  He has a broad range of research experience in aerosol and nanoparticle science and filtration technology and has over 280 journal papers and 40 patents.  He has developed several widely used commercial aerosol instruments and is a co-founder of Nanocopoeia for nano-formulation of pharmaceutical drugs.  Dr. Pui has received many awards, including the Max Planck Research Award (1993), the Humboldt Research Award for Senior U.S. Scientists (2000), the Fuchs Memorial Award (2010) -- the highest disciplinary award conferred jointly by the American, German and Japanese Aerosol Associations, and the Einstein Professorship Award (2013) by the Chinese Academy of Sciences (CAS).
讲座内容
We are developing green technologies that benefit sustainable environment which will enable people and the environment to prosper together. The Particle Technology Laboratory (PTL) has developed many instruments and samplers to perform atmospheric measurements, which helped to establish the U.S. PM2.5 standard. The effects of PM2.5 pollutants on the atmospheric visibility and human health will be addressed. The major PM2.5 sources in China have been identified to come from coal burning, vehicle emissions and steel/cement plants. Filtration is the principal means to control PM2.5 pollutants.  The Center for Filtration Research (CFR) at the University of Minnesota, consisting of 18 leading international filtration companies, was established to find filtration solutions to mitigate PM2.5 and other environmental pollutants. CFR investigators perform fundamental and applied research on air, gas and liquid filtration.  Fundamental research in measuring and filtering sub-20 nm particles in liquid and in air will be presented.  A Gasoline Particulate Filter (GPF) for Gasoline Direct Injection (GDI) engines has been developed to meet LEV3 and Euro 6 standard.  A disruptive innovation, namely, the Solar-Assisted Large-Scale Cleaning System (SALSCS), is proposed to mitigate PM2.5 pollutants in urban air.  A second generation SALSCS can be used to reduce CO2 in the atmosphere.  An integrative approach, from collaboration among academia, government, and industries, can effectively manage and mitigate the PM2.5 pollutants, particularly in China.
