这个CAREER项目由分析和表面化学项目支持，主要研究卤化氢与羟基功能化有机表面的界面吸附、扩散和反应。约翰·r·莫里斯教授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有重要意义的过程中令人感兴趣的反应。分子束散射从功能化自组装单层将用于检查这些相互作用。利用TOF分析监测散射产物的平动能，利用反射-吸收红外光谱对表面吸附的反应产物进行鉴定。气体表面能量传递，界面反应概率，以及共吸附溶剂分子在表面反应过程中的作用将被检查。这项研究工作将与VPI的分析化学入门课程的发展相结合，其中包括基于探究的合作学习方法。例子将取自现实世界的环境问题，并将与正在进行的基础研究联系起来的实验室。这个CAREER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都有相当大的兴趣，这个项目的教育部分将集中在这些环境联系上，将这项研究与研究生和本科生的教育结合起来。作为这个项目的一部分，探究性学习方法将被纳入介绍性分析课程。

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.
