Laboratory Investigations of the Chemistry of Newly Formed Atmospheric Aerosols

化学学部支持耶鲁大学的Christopher Johnson成为美国化学竞争力研究员。约翰逊博士将致力于研究被认为是大气气溶胶形成的重要前体的气相团簇的结构和动力学。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理解大气气溶胶形成和增长的基本化学和物理。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，这些模型清楚地说明了现代化学仪器是如何工作的。像约翰逊博士这样的研究旨在提高对大气气溶胶形成背后的化学和物理的理解。这是一个研究领域，目前有很大的不确定性。这种不确定性阻碍了例如更精确的气候模式的发展。约翰逊博士为扩大参与所做的努力，旨在教育那些来自代表性不足群体的年轻人，让他们了解现代化学仪器，希望能鼓励这些年轻人考虑从事科学事业。

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.
