Professor Douglas R. Worsnop

报告题目Mass Spectrometry of Atmospheric Aerosol:1 nanometer to 1 micron

间:201865日上午10:00

点:番禺校区祈福楼B1044会议室

报告摘要:

Despite much effort in the past decades, uncertainties in both climate impacts and health effects of atmospheric aerosols remain large. During the last ten years, aerosol mass spectrometry (AMS) has shown that sub-micron aerosol chemical composition is roughly 50:50 inorganic and organic worldwide, with secondary highly oxidized organics dominating the latter.Parallel application of chemical ionization mass spectrometry (CIMS) has provided the first observation of molecular cluster ions involved in atmospheric nucleation, including detection of highly oxidized multifunctional (HOM) organics in the gas phase.These results will be discussed in the context of their impact on atmospheric aerosols, clouds and climate.
