On January 11, at the invitation of Innovation Excellent Center for Urban Atmosphere Environment of CAS and Prof. Hong He’s Research Group, Professor David Y. H. Pui, the Regents Professor of the University of Minnesota and the Academician of the National Academy of Engineering, visited the Institute of Urban Environment, Chinese Academy of Sciences (IUE-CAS).

During his visit, Prof. Pui delivered an academic presentation entitled “Green Technologies for Sustainable Environment”. He first introduced the development of his Particle Technology Laboratory (PTL) and the outstanding achievements in particle purification of the Center for Filtration Research (CFR) of the University of Minnesota. Then, he mainly explained the efficiency of Solar Assisted Large-Scale Cleaning System (SALSCS) in particulate matter filtration. After system upgrading, SALSCS can also capture the greenhouse gas CO2 in the atmosphere. Finally, Prof. Pui proposed that academia, government and industry should work together to create a sustainable global environment.

This presentation was rich in content with warm atmosphere and expanded the participants' understandings of the frontier research fields such as particle control and CO2 emission reduction. Prof. Pui patiently and meticulously answered the questions of the participants.
