9317429加里森这个项目属于表面科学领域，重点是发展对高能粒子轰击引起的表面化学反应的坚定的理论理解。在这项为期三年的持续资助期间，加里森教授和她的学生将模拟KeV粒子轰击吸附在具有催化意义的金属表面的有机小分子，模拟30-200 eV有机分子撞击表面的表面诱导解离过程，以及最后KeV粒子轰击包括自组装单分子膜和聚合物在内的薄膜。重点将放在检查每个事件中发生的反应，然后将基本过程与实验观察联系起来。这项研究将现代表面理论和计算化学应用于理解粒子轰击如何在表面引起化学反应。在这项工作过程中得到的模型将对催化剂、有机薄膜和生物细胞等各种复杂材料的研究进展起到重要作用。***

9317429 Garrison This project is in the area of surface science and focusses on the development of a firm theoretical understanding of chemical reactions at surfaces induced by energetic particle bombardment. During the tenure of this three-year continuing grant, Professor Garrison and her students will model keV particle bombardment of small organic molecules adsorbed on metal surfaces which are of catalytic interest, surface induced dissociation processes in which a 30-200 eV organic molecule strikes a surface, and finally the keV particle bombardment of thin films including self assembled monolayers and polymers. The emphasis will be on examining reactions that occur during each of these events and then relating the fundamental processes to experimental observations. %%% This research brings modern surface theory and computational chemistry to bear on understanding of how particle bombardment causes chemical reactions at surfaces. Models derived in the course of this work will be important to progress in the study of complex materials as diverse as catalysts, organic thin films, and biological cells. ***
