2015年7月3日上午在我院B4-203会议室，美国加利福尼亚大学的Zhong-Min Wang博士为我们带了关于大气方面的2个学术报告，杨琛老师主持了本次报告会，近40名研究生参加了此次报告会。

  在第一个报告“A study using openface passive samplers to measure PM concentration and elemental composition in indoor environmental”中，Zhong-Min Wang博士介绍了一种测量室内PM的方法，该方法的优点在于采用被动式采样，从而减少了能源消耗，同时缩短了采样时间，利于实现自动化。在第二个报告“Characterization of Nanoparticles and Emission Variation from a LaserJet under Different Printing Conditions”中，介绍了打印机在不同打印条件下污染物的释放情况，为我们在办公生活中减少VOCs的排放提供了建议。

会后，在座同学和Zhong-Min Wang博士就减少VOCs排放，检测PM方法的优化等方面进行了互动和交流。

嘉宾简介：

Dr. Zhong-Min Wang is a Research Scientist at Environmental Health Laboratory of California Department of Public Health. His research area includes nanoparticle synthesis and characterization, aerosol sampling and generation, indoor or ambient air PM monitoring, forensic analysis for unknown powders and new materials, asbestos identification and quantification. He has also studied the health effect of nanoparticles and VOCs emitted from highway traffic, airport, and office machines in indoor environmental. He is also a microscopist and has been working in the microscopy lab for many years. He has published over 30 papers at peer reviewed journals, over 500 citations and holds two patents. He has been severed as a reviewer for a number of journals and panel member of US National Science Foundation proposal review for many years.
