9319640 White This research project is in the general area of Analytical and Surface Chemistry and in the subfield of surface dynamics. During the tenure of this three-year continuing grant, Professor White and his students will investigate the kinetics and dynamics of photon- and electron-driven processes in molecular adlayers. From the photon-driven processes, both photochemical and photophysical events, as well as the competition between them, will be investigated. Using low energy electrons, comparable bond breaking and energy transfer processes will be studied. The objective of the project is to increase our understanding of both the kinetics and dynamics that are operative in nonthermal systems at surfaces. %%% The primary objective of this research is to investigate the interactions of photons and electrons with molecules adsorbed on solid surfaces. Improved understanding of such systems is important to progress in many technologically important areas of research including catalysis, separations, and environmental chemistry. ***

9319640白色这个研究项目是在分析和表面化学的一般领域和表面动力学的子领域。 在为期三年的持续资助任期内，白色教授和他的学生将研究分子吸附层中光子和电子驱动过程的动力学和动力学。从光子驱动的过程中，光化学和光物理事件，以及它们之间的竞争，将被调查。 使用低能电子，可比的键断裂和能量转移过程将被研究。该项目的目的是增加我们的动力学和动力学的理解，在表面的非热系统中运作。 %本研究的主要目标是研究光子和电子与吸附在固体表面上的分子的相互作用。 提高对这些系统的理解对于许多重要的技术研究领域的进展是重要的，包括催化，分离和环境化学。 ***
