Structure and Dynamics of Chemisorption Through He Atom Scattering on Crystalline Surfaces (Analytical and Surface Chemistry):VPW

本研究的主要目的是研究 He原子化学吸附结构和动力学 散射晶体表面使用相对较新的 实验技术，氦原子表面光谱（HAS）。 当一系列长链烃， 烷基硫醇被化学吸附到金（111）表面上， 接受检查。 低能量的He原子，因为它们不反应， 或充电表面，是这些探头的选择， 系统. 了解的结构和动态的 研究的表面在许多领域都有影响，包括 催化，生物界面和膜的模型， 腐蚀保护和粘附问题。 项目 促进VPW计划目标，为以下方面提供机会： 女性在科学或工程领域的职业发展 通过研究，并鼓励其他妇女追求 在这些领域的职业生涯，通过调查人员的增强 在主办校园中树立榜样。 在这 第二个项目的拟议活动， 目标包括：组织一次加文奖章获得者研讨会 一系列杰出的女化学家;担任嘉宾 “科学、技术与社会”课程讲师; 与HAS研究小组互动，一个跨学科的 小组，通过日常研究接触和正式研讨会 介绍。

The primary objective of the proposed research is to study the structure and dynamics of chemisorption through He atom scattering on crystalline surfaces using the relatively new experimental technique, He atom-surface spectroscopy (HAS). Surfaces formed when a series of long-chained hydrocarbons, alkylthiols, are chemisorbed onto a gold (111) surface are to be examined. The low energy He atoms, since they do not react with or charge the surface, are the probe of choice for these systems. An understanding of the structure and dynamics of the surfaces to be studied has implications in many areas including catalysis, models for biological interfaces and membranes, corrosion protection, and adhesion problems. The project furthers VPW program objectives to provide opportunities for women to advance their careers in science or engineering through research, and to encourage other women to pursue careers in these areas through the investigators' enhanced visibility as role models on the host campuses. In this project, the proposed activities which contribute to the second objective include: organizing a Garvin Medalist Symposium series of outstanding women chemists; serving as a guest lecturer in "Science, Technology, and Society" course; and interacting with the HAS research group, an interdisciplinary group, through daily research contact and formal seminar presentations.
