项目摘要

This award is funded by the Environmental Chemical Sciences Program in the Chemistry Division of the National Science Foundation. Professor Rabi Musah of the Chemistry Department at the State University of New York at Albany (UAlbany) and collaborators at JEOL USA, Inc., a world leader in mass spectrometry, microscopy, and other analytical instrumentation, collaborate to develop new instruments that will measure volatile organosulfur compounds (VOSC) in the air in real time. Organosulfur species enter the atmosphere from both plants and other combustion processes and once in the atmosphere, VOSCs produce pollution, acid rain and cloud formation. The tools to be developed facilitate the study of not only the identity of organosulfur compounds in the atmosphere, but also their fate in the overall global sulfur cycle. The analytical tools and data processing software that are developed may find broad utility for analyses relevant to a range of other fields including chemistry, biochemistry, forensics chemistry, food sciences, agriculture, and medicine. Additionally, commercially available hardware and software are developed. The unique collaboration with JEOL USA Inc., extends the research capabilities of the UAlbany team. The fundamental research being performed by the team at UAlbany (i.e. investigations into the VOSC emission chemistry of vascular plants, and the study of the reactions of these compounds with other species in the environmental), occurs alongside more applied investigations at JEOL that are associated with extending the application of novel mass spectrometry technologies to solve a number of analytical problems in environmental science. Students and postdoctoral fellows benefit from immersion in both academic and industrial experiences, which serves to enhance their professional development.New ambient ionization mass spectrometric approaches are being developed to enable detection of individual plant-emitted volatile organosulfur compounds (VOSCs) in air in real time. The techniques are used for laboratory studies of the kinetics and products of the reactions of these newly discovered plant-derived VOSCs with environmentally-relevant free radicals. The developed analytical tools are expected to find broad utility for analyses relevant to a range problems in other fields. This work is performed in collaboration with scientists at JEOL USA Inc. The fundamental research is performed by the team at UAlbany, while JEOL pursues more applied investigations aimed at extending the application of novel ambient ionization mass spectrometry technologies to solve analytical problems in environmental science. Additionally, students benefit from immersion in both academic and industrial experiences, which serves to enhance their professional development.

该奖项由美国国家科学基金会化学部环境化学科学项目资助。纽约州立大学奥尔巴尼分校（UAlbany）化学系的Rabi Musah教授和JEOL USA， Inc.（质谱、显微镜和其他分析仪器领域的世界领导者）的合作者合作开发了实时测量空气中挥发性有机硫化合物（VOSC）的新仪器。有机硫物种通过植物和其他燃烧过程进入大气，一旦进入大气，vocs就会产生污染、酸雨和云的形成。即将开发的工具不仅有助于研究大气中有机硫化合物的身份，而且还有助于研究它们在全球硫循环中的命运。所开发的分析工具和数据处理软件可以在化学、生物化学、法医化学、食品科学、农业和医学等一系列其他领域的分析中找到广泛的用途。此外，还开发了商用硬件和软件。与JEOL美国公司的独特合作，扩展了UAlbany团队的研究能力。UAlbany团队正在进行的基础研究（即调查维管植物的VOSC排放化学，以及研究这些化合物与环境中其他物种的反应）与JEOL的更多应用研究一起进行，这些研究与扩展新型质谱技术的应用有关，以解决环境科学中的许多分析问题。学生和博士后将受益于沉浸在学术和行业经验中，这有助于促进他们的专业发展。人们正在开发新的环境电离质谱方法，以便实时检测空气中单个植物排放的挥发性有机硫化合物（vosc）。这些技术用于实验室研究这些新发现的植物源性vocc与环境相关自由基反应的动力学和产物。所开发的分析工具有望在与其他领域的一系列问题相关的分析中找到广泛的用途。这项工作是与JEOL USA Inc.的科学家合作完成的。基础研究由UAlbany的团队进行，而JEOL则进行更多的应用研究，旨在扩展新型环境电离质谱技术的应用，以解决环境科学中的分析问题。此外，学生受益于沉浸在学术和行业经验，这有助于加强他们的专业发展。
