EMSI: Role of Environmental Molecular Interfaces on the Chemical and Biological Reactivity of Pollutants

授予俄亥俄州立大学的环境分子科学研究所(EMSI)奖得到了化学部特别项目办公室和数学和物理科学局多学科活动办公室的支持。该奖项支持的Patrick G.Hatcher和Samuel J.Traina将研究环境分子界面对大气、水和土壤过程的化学和生物活性的作用。这个多学科项目还支持来自俄亥俄州立大学不同系的其他16名教职员工。此外，还向保罗·戴维茨(波士顿学院)、萨蒂什·梅内尼(普林斯顿大学)和伊丽莎白·格思里(大学)提供支助。田纳西州)通过分奖。将研究两个主要的技术推动力，1)空气/水/有机界面和冰界面的大气过程，2)土壤、沉积物和水介质中污染物与水/固体界面过程的相互作用。分子水平上的冰芯研究将提供对过去和未来化学过程的理解。这些研究将对与生态系统破坏和退化有关的问题产生广泛影响，并对人类和自然生物群产生长期有害影响。为了支持技术推进，在使用和开发先进的分析方法方面做出了相当大的努力。阿贡国家实验室的工作人员将提供激光解吸质谱学、X射线吸收光谱分析、固态和空间分辨核磁共振光谱分析以及同位素标记研究方面的专业知识。已经建立和扩大了与Aerodyne Research在气溶胶和云室化学方面的工业合作，以及埃克森美孚和汽巴特种化学品在目标污染地点的合作。拟议的外展培训计划涉及本科生、研究生和研究生，以吸引年轻人投身环境分子科学的职业。此外，俄亥俄州立大学的外展计划将与阿贡国家实验室协调。这一基础的多学科研究将促进我们对环境分子界面对大气、水和土壤过程的化学和生物活性的作用的理解。这些研究还将在分子水平上提供信息，即污染物与土壤、沉积物和水介质中的水/固体界面过程的相互作用。包括拟议的网站在内的外联方案将提供环境分子科学方面的培训和信息。

This Environmental Molecular Science Institute (EMSI) Award to Ohio State University is supported by the Special Projects Office in the Chemistry Division, and the Office of Multidisciplinary Activities of the Mathematical and Physical Sciences Directorate. Patrick G. Hatcher and Samuel J. Traina supported by this award will study the role of environmental molecular interfaces on the chemical and biological activity of atmospheric, water and soil processes. This multidisciplinary program also supports sixteen other faculty members from different departments of Ohio State University. In addition, support is also provided to Paul Davidovits (Boston College), Satish Myneni (Princeton University) and Elizabeth Guthrie (Univ. of Tennessee) through subawards. Two major technical thrusts will be studied, 1) atmospheric processes at air/water/organic interfaces and ice interfaces, and 2) interactions of pollutants with water/solid interfacial processes in soils, sediments and aquatic media. Ice core studies at molecular level will provide an understanding of past and future chemical processes. These studies will have broad impact on issues related to ecosystem impairment and degradation, and long term deleterious impact on human and natural biota. In support of the technical thrusts, is a sizable effort in the use and development of advanced analytical methods. Staff from Argonne National Laboratory will provide expertise in laser desorption mass spectrometry, x-ray absorption spectrometry, solid state and spatially-resolved Nuclear Magnetic Resonance Spectrometry, and isotopic labeling studies. Industrial collaborations with Aerodyne Research on aerosol and cloud chamber chemistry, and Exxon and Ciba Specialty Chemicals on targeted contaminated sites have been established and expanded. Outreach training programs proposed involved undergraduate, graduate and postgraduate students to attract young people to careers in environmental molecular sciences. In addition, the outreach program at Ohio State University will be coordinated with Argonne National Laboratory. This fundamental multidisciplinary research will advance our understanding of the role of environmental molecular interfaces on the chemical and biological activity of atmospheric, water and soil processes. The studies will also provide information at molecular level, the interactions of pollutants with water/solid interfacial processes in soils, sediments and aquatic media. The outreach programs including the web site proposed will provide training in and information about environmental molecular sciences.
