This CAREER project, supported by the Analytical and Surface Chemistry Program, focusses on the interfacial adsorption, diffusion, and reaction of hydrogen halides with hydroxy-functionalized organic surfaces. Professor John R. Morris and his coworkers of Virginia Polytechnic Institute and State Univeristy will examine reactions of interest in a number of environmentally important processes. Molecular beam scattering from functionalized self-assembled monolayers will be used to examine these interactions. The translational energy of the scattered product species will be monitored by TOF analysis, and reflection-absorption infrared spectroscopy will be used to identify the surface adsorbed reaction products. Gas-surface energy transfer, interfacial reaction probability, and the role of coadsorbed solvent molecules on the surface reaction process will be examined. This research effort will be integrated with the development of an introductory analytical chemistry course at VPI incorporating inquiry based cooperative learning methods. Examples will be drawn from real world environmental problems, and will be tied to the basic research underway in the P.I.'s laboratory.This CAREER project focusses on the basic understanding of the interfacial chemistry of hydrogen halides, using detailed dynamic experimental methods. This surface chemistry is of considerable interest in a number of environmental applications, and the educational component of this project will focus on these environmental connections in the integration of this research with the education of graduate and undergraduate students. Inquiry based learning methods will be incorporated into the introductory analytical course offerings as part of this project.

这个CAREER项目，由分析和表面化学计划的支持，专注于界面吸附，扩散和卤化氢与羟基官能化的有机表面的反应。 约翰·R. 莫里斯和他在弗吉尼亚理工学院和州立大学的同事们将研究一些对环境重要的过程中感兴趣的反应。 从功能化的自组装单分子膜的分子束散射将被用来检查这些相互作用。 散射产物物种的平移能将通过TOF分析来监测，并且反射-吸收红外光谱将用于识别表面吸附的反应产物。 气体表面能量转移，界面反应的概率，和共吸附的溶剂分子的作用，表面反应过程将被检查。 这项研究工作将与VPI的介绍性分析化学课程的开发相结合，采用基于探究的合作学习方法。 将从真实的世界环境问题中提取例子，并将与P.I.正在进行的基础研究联系起来。这个职业项目的重点是对卤化氢的界面化学的基本理解，使用详细的动态实验方法。 这种表面化学在许多环境应用中具有相当大的兴趣，本项目的教育部分将侧重于将本研究与研究生和本科生的教育相结合的环境联系。 作为本项目的一部分，基于探究的学习方法将被纳入介绍性分析课程。
