报告内容摘要:
Plasma is usually considered as the fourth state of matter (aside from solid, liquid and gas). It is a collection of neutrals, ions, and electrons characterized by a collective behavior. You probably do not know, 99% of the universe is in plasma state. Biological application of plasmas were first employed in the late 1850s when Siemens used a dielectric barrier discharge (DBD) to generate ozone and used the ozone to clean water from biological contaminants. However, no systematic research was conducted to understand the interaction between plasmas and biological cells until more than 130 years later, in the mid-1990s, when atmospheric pressure non-equilibrium plasmas became a “hot” research topic, that investigations aimed at elucidating the effects of plasmas on bacterial cells were initiated. This talk will discuss a few major atmospheric pressure plasma sources (e.g., plasma needle, dielectric barrier discharge, argon plasma coagulator, free-electrode DBD, plasma micro jet), their operating parameters and characterization. This talk further intends to summarize a few recently developed biological and biomedical applications of atmospheric pressure cold plasmas and most importantly to build a bridge between physicists, engineers and biologists for this rising field.

报告人简介:
Prof. WeiDong Zhu is an Assistant Professor of Physics in the Department of Applied Science and Technology – Physics Division at Saint Peter’s College since 2007. Prior to SPC, Prof. Zhu held a position as a Post Doctoral Research Associate at the Frank Reidy Research Center for Bioelectrics at Old Dominion University in Norfolk, VA. During his postdoctoral position, Prof. Zhu worked on novel microhollow cathode discharges (MHCD) under the guidance of Prof. Karl H. Scheonbach. Previously, Prof. Zhu did his doctoral dissertation under the guidance of Prof. Kurt H. Becker and Abraham Belkind in pulsed DC magnetron plasma sputtering. Among other activities, Prof. Zhu was an assistant to the organizers of the 2nd International Workshop on Microplasmas (IWM 2004) held in Hoboken, New Jersey in October, 2004. Most recently, Prof. Lopez is one of the local organizers of the “Complex Plasma Summer Institute”, a summer school on plasma science to help from July 30th to August 8th, 2008 at Stevens Institute of Technology. Prof. Zhu’s current research interest spans from basic research on atmospheric pressure non-equilibrium plasmas, plasma sources, plasma diagnose to environmental, biological and biomedical application of microplasmas. Prof. Zhu is a member of American Physical Society (APS) and a member of Institute of Electrical and Electronic Engineers (IEEE).
