CAREER: The Direct Determination of Rate Constants and Branching Ratios for Methylperoxy Reactions Under Atmospherically Relevant Conditions

该奖项是在美国国家科学基金会职业计划下颁发的，由大气化学和实验物理化学计划共同支持。该项目的研究部分包括实验化学动力学测量，以解决甲基过氧自由基（CH3O2）在对流层和平流层过程中的作用，重点关注可能影响臭氧破坏和生产周期的反应。第二个目标是进一步发展化学电离质谱（CIMS）技术，使其成为实验室和现场检测大气物种的一种有前途的新方法。紊流- cims方法将用于测量对流层和平流层下层的温度和压力条件下的速率。此外，将开发敏感和选择性的化学电离方案，用于低绝对浓度的测量和对反应物和产物的明确监测。该教育计划的主要目标是通过系统地实施创新的教学技术，并在课堂和本科生研究环境中引入环境化学主题，提高霍普学院化学课程的质量。我们将采用合作学习的方法，并将研究相关的案例纳入教学。

This award was made under the NSF CAREER Program and is supported jointly by the Atmospheric Chemistry and the Experimental Physical Chemistry Programs. The research component of this project consists of experimental chemical kinetics measurements that address the role of the methyl peroxy radical (CH3O2) in tropospheric and stratospheric processes, with a focus on reactions which may affect ozone destruction and production cycles. A secondary objective is to further the development of the chemical ionization mass spectrometry (CIMS) technique as a promising new method for both laboratory and field detection of atmospheric species. The turbulent flow-CIMS method will be used to measure rates at temperature and pressure conditions characteristic of the troposphere and lower stratosphere. In addition, sensitive and selective chemical ionization schemes will be developed for measurements at low absolute concentrations and for unambiguous monitoring of reactants and products. The primary objective of the education plan is to enhance the quality of Hope College's chemistry program through a systematic implementation of innovative teaching techniques and by introducing environmental chemistry topics in both the classroom and the undergraduate research setting. Collaborative learning techniques will be used, and research-related case studies will be incorporated into the teaching.
