In this award, funded by the Experimental Physical Chemistry Program of the Division of Chemistry, Professor Lai-Sheng Wang of Washington State University, together with his postdoctoral, graduate and undergraduate student researchers, will study the structural evolution and chemical properties of metal clusters. Topics for investigation include large gold clusters (more than 20 atoms), endohedral gold clusters, tungsten molecules and clusters, as well as gold clusters with chemisorbed CO and oxygen molecules. These species will be studied through a combination of mass spectrometry, photoelectron spectroscopy combined with theoretical methods.Gold nanoparticles have a wide range of applications in catalysis, molecular electronics and biology. Careful studies like those of Prof. Wang and his group build a knowledge base of the electronic and chemical properties of these species which help to inform the various nanotechnology areas where these substances play a role. The students receiving research training in Prof. Wang's research group will learn to use sophisticated equipment in a unique university/national laboratory environment. Prof. Wang's gold cluster research has captured the public interest, and Prof. Wang continues to be an excellent ambassador for science.

在这个由化学系实验物理化学计划资助的奖项中，华盛顿州立大学的王来胜教授将与他的博士后、研究生和本科生研究人员一起，研究金属团簇的结构演化和化学性质。 研究的主题包括大的金团簇（超过20个原子），内生的金团簇，钨分子和团簇，以及化学吸附CO和氧分子的金团簇。 这些物种将通过质谱、光电子能谱结合理论方法进行研究。金纳米粒子在催化、分子电子学和生物学等领域有着广泛的应用。 像王教授和他的团队这样的仔细研究建立了这些物质的电子和化学性质的知识库，这有助于为这些物质发挥作用的各种纳米技术领域提供信息。 在王教授的研究小组接受研究培训的学生将在独特的大学/国家实验室环境中学习使用先进的设备。 王教授的金团簇研究引起了公众的兴趣，王教授继续成为一名优秀的科学大使。
