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.

该职业项目在分析和表面化学计划的支持下，重点介绍氢卤化物与羟基官能化有机体表面的界面吸附，扩散和反应。 约翰·R·莫里斯（John R. 来自功能化的自组装单层的分子束散射将用于检查这些相互作用。 散射产物物种的翻译能将通过TOF分析监测，并且将使用反射吸收红外光谱法来识别表面吸附的反应产物。 将检查气体表面能传递，界面反应概率以及共掺杂的溶剂分子在表面反应过程中的作用。 这项研究工作将与VPI的入门分析化学课程的开发集成，该课程结合了基于查询的合作学习方法。 实例将来自现实世界中的环境问题，并将与P.I.实验室的基础研究相关联。该职业项目的重点是使用详细的动态实验方法，重点介绍了对氢卤化物的界面化学的基本理解。 这种表面化学在许多环境应用中引起了极大的兴趣，该项目的教育部分将集中在这项研究与研究生和本科生的教育中。 作为本项目的一部分，基于查询的学习方法将纳入入门分析课程中。
