The Macromolecular, Supramolecular and Nanochemistry (MSN) program of the Division of Chemistry will support the research program of Prof. Gangli Wang of Georgia State University. Prof. Wang and his students will synthesize and characterize the properties of gold and copper nanoclusters that are capped with multi-dentate thiols for chemical stabilization. The energetics of metal nanoclusters will be investigated with optical and electrochemical techniques. Nano-sized electrodes will be fabricated to quantitatively study the electron transfer kinetics in these nanoclusters. A correlation will be established between the energetics and functionality of metal nanoclusters and their compositions and structures. The project will address basic questions and issues that are at the heart of many fields such as energy, nanoscience, surface science, and chemistry. The structure-property correlation established on gold and copper nanoclusters could potentially reveal the active sites in catalytic processes. The nanoclusters could also be used in photovoltaics devices. The proposed research will provide state-of-the-art education and training opportunities for students in this cutting edge, interdisciplinary research area.

化学系的大分子、超分子和纳米化学（MSN）项目将支持美国佐治亚州立大学王刚立教授的研究项目。王教授和他的学生将合成并表征金和铜纳米簇的性质，这些纳米簇被多齿状硫醇覆盖以实现化学稳定。利用光学和电化学技术研究金属纳米团簇的能量学。为了定量研究这些纳米团簇中的电子传递动力学，将制备纳米电极。将建立金属纳米团簇的能量学和功能与其组成和结构之间的相关性。该项目将解决许多领域的核心问题，如能源、纳米科学、表面科学和化学。在金和铜纳米团簇上建立的结构-性能相关性可以潜在地揭示催化过程中的活性位点。纳米团簇也可用于光伏器件。拟议的研究将为学生在这个前沿的跨学科研究领域提供最先进的教育和培训机会。
