Specific Solvation and Solvent Structure at Liquid Interfaces

在这个由化学系实验物理化学项目资助的奖项中，罗伯特·A·马里兰州大学帕克分校的步行者和他的本科生和研究生将继续他们的工作，研究液体界面处的溶剂结构。 他们将通过询问位于界面处的探针物质和溶剂分子来做到这一点;这将通过二次谐波产生和振动和频光谱来完成。 关于液体在界面处的结构还有许多问题，步行者教授和他的研究小组正在努力开发液体在液/液、液/固和液/汽界面处如何行为的分子水平图像。 鉴于这些类型的接口在自然界中的普遍存在，预计这项研究的结果将在许多学科和技术应用中具有广泛的适用性。除了支持研究的更广泛的科学和技术影响外，步行者教授继续指导年轻科学家，并致力于一些项目，通过罗林森奖学金计划（Rollinson Fellowship Programme）和本科课程开发中的“眼见为实”计划（Seeing is Believing），将现代化学的各个方面带给更广泛的受众。

In this award, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Robert A. Walker of the University of Maryland, College Park, and his undergraduate and graduate research students will continue their work studying solvent structure at liquid interfaces. They will do this through the interrogation of probe species and solvent molecules situated at the interface,; this will be done with second harmonic generation and vibrational sum frequency spectroscopies. Many questions remain about the structure of liquids at interfaces, and Prof. Walker and his research team are striving to develop molecular-level pictures of how liquids behave at liquid/liquid, liquid/solid, and liquid/vapor interfaces. Given the ubiquity of these kinds of interfaces in nature, the results of this research are expected to have broad applicability across a number of disciplines and technology applications. Besides the broader scientific and technological impacts of the research being supported, Prof. Walker continues mentoring young scientists, and works on a number of projects to bring aspects of modern chemistry to a broader audience, through programs, like the Rollinson Fellowship Programfor undergraduate research, and the "Seeing is Believing" program in undergraduate curriculum development.
