With support from the Chemical Measurement and Imaging Program, and co-funding from the Chemical Catalysis Program in the Division of Chemistry, Professors Louis Bouchard and Omar Yaghi and their groups at University of California, Los Angeles are proposing to develop novel methodologies to visualize chemical reactions in real-time and in a non-invasive manner. Chemical catalysis and the optimization of chemical reactors rely on the accurate knowledge of chemical reaction thermodynamics, but methods to probe reaction dynamics non-invasively are currently lacking. Such methods would enable the optimization of catalysts and help improve the design of chemical reactors. Any improvements in the reaction efficiency could potentially translate into economic savings and reduced negative impact of chemical catalysis to the environment. In this project, the reserachers will develop novel imaging methods to be applied to existing and emerging catalysts such as metal organic frameworks and metal nanoparticle catalysts, which are attractive not only to conventional industrial catalysis but also for modern microreaction technology. The learned knowledge from the development of novel imaging technology will be used to devise new experiments to benefit undergraduate education. The researchers are involved in developing new experiments for undergraduate chemistry labs and in developing extracurricular teaching activities that benefit local public schools, where many minority students are enrolled.

在化学测量和成像计划的支持下，以及化学系化学催化计划的共同资助下，加州大学洛杉矶分校的Louis Bouchard和Omar Yaghi教授及其团队正在提议开发新的方法，以实时和非侵入性的方式可视化化学反应。 化学催化和化学反应器的优化依赖于化学反应热力学的准确知识，但目前缺乏无创探测反应动力学的方法。 这些方法将能够优化催化剂，并有助于改进化学反应器的设计。 反应效率的任何改进都可能转化为经济节约和减少化学催化对环境的负面影响。在该项目中，研究人员将开发新的成像方法，用于现有和新兴的催化剂，如金属有机框架和金属纳米颗粒催化剂，这不仅对传统的工业催化，而且对现代微反应技术具有吸引力。 从新的成像技术的发展学到的知识将被用来设计新的实验，有利于本科教育。研究人员参与开发本科化学实验室的新实验，并开发有益于当地公立学校的课外教学活动，许多少数民族学生就读于这些学校。
