Chemistry and Self-Assembly of Molecules at Liquid-Solid and Vacuum-Solid Interfaces

在化学系实验物理化学计划的支持下，哥伦比亚大学的George Flynn教授将在该奖项中进行以下方面的研究：(1)分子在液-固和真空-固界面上的自组装，(2)四氯化碳在氧化铁表面的反应机理。实验将利用扫描隧道显微镜技术，结合程序升温解吸测量。(1)中的一些研究将与哥伦比亚大学的伯尔尼小组合作，用一个耦合的理论程序来补充。弗林教授的研究应该会对驱动自组装的一些过程提供重要的见解。这些洞察力对于开始进行界面自组装的智能控制和操作是必要的--这可能会在许多技术领域产生广泛影响，从新的光电材料到化学和生物传感器。此外，四氯化碳在氧化铁表面的反应研究有望有助于理解这种卤代烃在环境中的氧化过程。弗林教授的工作还将有助于博士后、研究生和本科生研究人员的教育和培训。

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.
