Laboratory Investigations of the Chemistry of Newly Formed Atmospheric Aerosols

化学部支持耶鲁大学的克里斯托弗约翰逊作为美国竞争力化学研究员。 约翰逊博士将致力于研究气相团簇的结构和动力学，这些团簇被认为是形成大气气溶胶的重要前体。 PI将与气溶胶对气候和环境影响中心的科学家合作。 这项研究的最终目标是更好地了解大气气溶胶形成和增长的基本化学和物理学。 为了扩大参与范围，约翰逊博士将开发简单的动手模型，供学生和公众使用，这些模型将阐明现代化学仪器的工作原理。 像约翰逊博士这样的研究旨在加深对大气气溶胶形成背后的化学和物理学的理解。 这是一个目前存在很大不确定性的研究领域。 这种不确定性阻碍了例如更精确的气候模型的开发。 约翰逊博士正在努力扩大参与，目的是教育代表性不足群体的年轻人了解现代化学仪器，希望鼓励这些年轻人考虑从事科学工作。

The Division of Chemistry supports Christopher Johnson of Yale University as an American Competitiveness in Chemistry Fellow. Dr. Johnson will work on studying the structure and dynamics of the gas-phase clusters that are thought to be important precursors in the formation of atmospheric aerosols. The PI will collaborate with scientists at the Center for Aerosol Impacts on Climate and the Environment. The ultimate goal of this research is to develop a better understanding of the fundamental chemistry and physics of atmospheric aerosol formation and growth. For his plan for broadening participation, Dr. Johnson will develop simple hands-on models for use by students and members of the public, which make clear how modern chemical instrumentation works. Research like that of Dr. Johnson is aimed at developing an improved understanding of the chemistry and physics behind the formation of atmospheric aerosols. This is an area of research for which there is currently a great deal of uncertainty. This uncertainty hinders the development of e.g. more accurate models of the climate. The efforts at broadening participation being pursued by Dr. Johnson are aimed at educating young people from underrepresented groups about modern chemical instrumentation, in the hopes of encouraging these young people to consider careers in science.
