Gas-Surface Chemistry of Self-Assembled Monolayers

美国国家科学基金会化学部的分析和表面化学项目正在支持圣母大学化学和生物化学系的S. Alex Kandel教授的研究项目，题为“自组装单层的气体表面化学”。坎德尔教授和他的学生正在研究，当表面暴露于活性气体中时，组成表面的原子和分子的精确排列如何影响化学反应的速率和类型。坎德尔的研究小组使用扫描隧道显微镜来制作原子尺度的电影，绘制出化学反应过程中单个分子的位置和行为。他们专门研究有机薄膜与氢、氧和氯原子的反应。这项研究可能会导致新材料的开发，这些材料在火焰、等离子体和高层大气等反应性化学环境中具有更好的稳定性。该项目将为物理化学中心学科以及表面科学和纳米技术跨学科领域的本科生和研究生提供良好的培训机会。

The Analytical and Surface Chemistry Program of NSF Division of Chemistry is supporting the research program of Professor S. Alex Kandel in the Department of Chemistry and Biochemistry at the University of Notre Dame under a project titled, "Gas-Surface Chemistry of Self-Assembled Monolayers." Professor Kandel and his students are investigating how the exact arrangement of atoms and molecules that make up a surface influence the rate and type of chemical reactions that occur when the surface is exposed to reactive gases. The Kandel research group uses scanning tunneling microscopy to develop atomic-scale movies that map out the location and behavior of individual molecules during the course of a chemical reaction. They specifically investigate the reactions of thin organic films with hydrogen, oxygen, and chlorine atoms. The study could lead to development of new materials with improved stability in reactive chemical environments such as flames, plasmas, and the upper atmosphere. The project will provide excellent training opportunities to undergraduate and graduate students in the central discipline of physical chemistry and in the interdisciplinary fields of surface science and nanotechnology.
