PAIR Seminar: Prof. David Y.H. PUI of University of Minnesota delivers "'Nanoparticle Technologies in Microelectronics, Air Quality, Health Effects, and Filtration"

Abstract

Nanoparticles are the basic building blocks of nanotechnology. I guest-edited a Special Issue of Journal of Aerosol Science in 1997 on Nanometer Particles (before the nanoparticles word was coined): A New Frontier for Multidisciplinary Research. I wrote in the editorial that “as a new frontier in particle and aerosol research, nanoparticle research has significant potential for scientific breakthrough and new technological innovations”. There were 15 papers in the special issue, covering the topics of material synthesis, health effects, microcontamination, biotechnology, emission control, instrumentation, and nanoparticle physics and chemistry.

In this seminar, I will address the recent developments in nanoparticle technologies on the research topics that my group has performed. Four multidisciplinary topics will be covered: 1. Microelectronics: contamination control in Extreme UV Lithography (EUVL) system; 2. Air Quality: PM_2.5, respirators, indoor and urban pollution controls; 3. Health Effects: nanomedicine, bioaerosol sensor, UV-C decontamination; 4. Filtration: AI deep learning for predicting performance of filter media, wildfires loading on electret filter efficiency, large-scale direct-capture of atmospheric CO₂ to mitigate climate change.
