Photochemistry and Reactions on Carbonaceous Aerosol

9703167 Morris该项目将作为NSF CAREER Program的一部分进行。本研究的目的是在模拟夜间城市大气条件下，研究含碳气溶胶粒子和二氧化氮的竞争机制和产物分布。实验研究将涉及激光光谱、泵浦探针和基质分离技术，以研究空气中气溶胶的非均相化学。利用从头算分子轨道技术进行的理论研究将与气溶胶碳质粒子的实验研究并行进行。在教育计划方面，研究者将为研究生、本科生和高中生开发和实施研究机会。PI特别感兴趣的是向学生教授实验实验室技术，使他们熟悉最先进的仪器和大气化学研究的建模技术。PI打算在华盛顿特区都会区的公立学校促进科学教学，特别是在大气和空间科学领域。这项外展计划的目标是加强和加强早期科学教育，以增加少数民族学生从事科学事业的人数。

9703167 Morris The project will be conducted as part of the NSF CAREER Program. The goal of this research is to study competing mechanisms and product distributions of carbonaceous aerosol particles and NO2 under simulated nighttime conditions for urban atmospheres. The experimental studies will involve laser spectroscopy, pump-probe, and matrix isolation techniques to investigate the heterogeneous chemistry of airborne aerosols. Theoretical studies using ab initio molecular orbital techniques will be conducted as a parallel effort to the experimental studies of aerosol carbonaceous particles. For the educational plan, the investigator will develop and implement research opportunities for graduate, undergraduate, and high school students. The PI is particularly interested in teaching experimental laboratory techniques to students that will familiarize them with state-of-the-art instrumentation and modeling techniques for atmospheric chemical research. The PI intends to promote science instruction in the Washington, D.C. metro area public schools, especially in the areas of atmospheric and space sciences. The goal of this outreach program is to enhance and to reinforce science education at an early stage in order to increase the number of minority students engaged in science careers.
