项目摘要

The Division of Chemistry supports Jonathan Raff of the University of California - Irvine as an American Competitiveness in Chemistry Fellow. Dr. Raff will study the heterogeneous reactions of NOx compounds under atmospherically-relevant conditions. Specifically, he will investigate the mechanism for the heterogeneous production of HONO from nitrogen dioxide. Raff will work in collaboration with scientists at Irvine as well as at the Environmental Molecular Sciences Laboratory at the Pacific Northwest National Laboratory. In his plan for broadening participation, Dr. Raff will work with students and teachers (Grades 7-12) from the Los Angeles metropolitan area to develop curriculum materials that explore the chemistry of nitrogen oxides in the environment.Research like that of Dr. Raff is aimed at developing a better understanding of the chemistry that takes place in the atmosphere. The presence of minute quantities of some chemical species can have profound effects on the chemical composition of the atmosphere. The collection of all of these species, and their interactions is like a horrendously complicated puzzle. Dr. Raff is exploring one of the missing pieces of this complex chemical puzzle. The curriculum development work that Raff is undertaking is devoted to increasing the interest in chemistry by underrepresented students in the Los Angeles area.

化学部支持加州大学欧文分校的乔纳森·拉夫作为美国化学竞争力研究员。 Raff博士将研究在大气相关条件下NOx化合物的非均相反应。具体而言，他将研究从二氧化氮中异质生产HONO的机制。 Raff将与Irvine以及太平洋西北国家实验室环境分子科学实验室的科学家合作。在他扩大参与的计划中，Raff博士将与来自洛杉矶大都会地区的学生和教师（7-12年级）合作，开发探索环境中氮氧化物化学的课程材料。像Raff博士这样的研究旨在更好地了解大气中发生的化学反应。微量的某些化学物质的存在会对大气的化学组成产生深远的影响。所有这些物种的集合，以及它们之间的相互作用就像一个可怕的复杂的谜题。拉夫博士正在探索这个复杂化学谜题中缺失的一部分。拉夫正在进行的课程开发工作致力于提高洛杉矶地区代表性不足的学生对化学的兴趣。
