Surface chemical reactions are critically important to a number of high-impact technologies including catalysts for fuels production and pollution prevention, and fabrication of solar cells and microelectronics. One could control these reactions better if one understood how these energies correlate with surface structure. In this award, funded by the Chemical Structure, Dynamics, and Mechanisms and Chemical Measurement and Imaging Programs of the Division of Chemistry, Professor Campbell will measure the energies of surface chemical reactions. His laboratory has developed microcalorimetry tools that allow the study of single crystal surfaces, which will be employed to measure the energies of a variety of surface species of importance in the design of better catalysts, solar cells and microelectronics, and correlated with atomic-level structural details. This will provide a deeper understanding of the relationships between surface chemical reactivity and structure. These energies also will provide important benchmarks for testing the accuracy of new theoretical/computational methods.This work will also provide strong interdisciplinary, research-based education for many graduate and undergraduate students and postdocs. They will get hands-on experience with state-of-the-art research instrumentation and its design, and ample opportunities for international collaborations and interactions at national laboratories. They will be mentored in scientific leadership, public speaking and responsible conduct of research.

表面化学反应对许多高影响力技术至关重要，包括用于燃料生产和污染预防的催化剂，以及太阳能电池和微电子的制造。 如果人们了解这些能量如何与表面结构相关联，就可以更好地控制这些反应。在这个奖项，由化学结构，动力学和机制和化学测量和成像计划的化学部的资助，教授坎贝尔将测量表面化学反应的能量。他的实验室已经开发出微量热工具，允许研究单晶表面，这将被用来测量各种表面物种的能量，这些物种在设计更好的催化剂，太阳能电池和微电子产品中具有重要意义，并与原子级结构细节相关。 这将使人们更深入地了解表面化学反应性和结构之间的关系。 这些能量也将为测试新的理论/计算方法的准确性提供重要的基准。这项工作也将为许多研究生和本科生以及博士后提供强大的跨学科，以研究为基础的教育。 他们将获得最先进的研究仪器及其设计的实践经验，以及在国家实验室进行国际合作和互动的充分机会。 他们将在科学领导，公开演讲和负责任的研究行为方面得到指导。
