In this award, supported by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. George Flynn of Columbia University will conduct research on (1) the self-assembly of molecules at interfaces, both liquid-solid and vacuum-solid interfaces, and (2) the reaction mechanism of carbon tetrachloride on iron oxide surfaces. Experiments will utilize scanning tunneling microscopy techniques, combined with temperature programmed desorption measurements. Some of the studies in (1) will be complemented with a coupled theoretical program, in collaboration with the Berne group at Columbia University. The studies by Prof. Flynn should provide important insight into some of the processes that drive self-assembly. These insights are necessary in order to begin to undertake the intelligent control and manipulation of self-assembly at interfaces - - which could likely have a broad impact in many technological areas, from new electro-optical materials to chemical and biological sensors. In addition, the study of reactions of carbon tetrachloride at iron oxide surfaces is expected to contribute to the understanding of the oxidation of this halocarbon in the environment. Prof. Flynn's work will also contribute to the education and training of post-doctoral, graduate and undergraduate student researchers.

在该奖项中，由化学部实验物理化学计划支持，哥伦比亚大学的乔治弗林教授将进行以下研究：（1）分子在界面（液-固和真空-固界面）的自组装，以及（2）四氯化碳在氧化铁表面上的反应机理。 实验将利用扫描隧道显微镜技术，结合温度程序解吸测量。 与哥伦比亚大学的伯尔尼小组合作，（1）中的一些研究将得到一个耦合理论项目的补充。 弗林教授的研究应该为推动自组装的一些过程提供重要的见解。 这些见解是必要的，以便开始进行界面自组装的智能控制和操纵-这可能会在许多技术领域产生广泛的影响，从新的电光材料到化学和生物传感器。 此外，对四氯化碳在氧化铁表面的反应的研究预计将有助于了解这种卤化碳在环境中的氧化情况。 弗林的工作也将有助于博士后，研究生和本科生研究人员的教育和培训。
