The Environmental Chemical Sciences (ECS) program of the Division of Chemistry will support the research program of Prof. Vicki Grassian of the University of Iowa. Prof. Grassian and her students will carry out detailed mechanistic studies using different spectroscopic tools, isotope labels, microscopy and calculations to provide a clearer understanding of chemical reactions that are of atmospheric significance. Prof. Grassian and her students will study the surface photochemistry of adsorbed chromophores, in particular the nitrate ion, on different surfaces and in different chemical environments. They will also study the surface chemistry, photochemistry and redox chemistry of anthropogenic metal oxide dusts. The study is potentially transformative since it could change the way we think about the chemistry of mineral dust aerosol in the atmosphere and its impact on our climate. The project will provide excellent educational opportunities for students, including some from under represented groups, desiring to work at the forefront of environmental science.

化学系的环境化学科学(ECS)计划将支持爱荷华大学Vicki Grassian教授的研究计划。Grassian教授和她的学生将使用不同的光谱工具、同位素标记、显微镜和计算进行详细的机理研究，以更清楚地了解具有大气意义的化学反应。Grassian教授和她的学生将研究不同表面和不同化学环境中被吸附的发色团的表面光化学，特别是硝酸根离子。他们还将研究人为金属氧化物粉尘的表面化学、光化学和氧化还原化学。这项研究具有潜在的变革性，因为它可能会改变我们对大气中矿物粉尘气溶胶化学成分的看法，以及它对气候的影响。该项目将为学生提供极好的教育机会，包括一些来自代表性不足群体的学生，他们希望在环境科学的前沿工作。
