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.

在该奖项中，由华盛顿州立大学的莱尚·王（Lai-Sheng Wang）教授及其博士后，研究生和本科生研究人员资助，将研究金属簇的结构演化和化学性质。 进行研究的主题包括大的金簇（20多个原子），内膜的金簇，钨分子和簇，以及具有化学吸附CO和氧分子的金簇。 这些物种将通过质谱，光电子光谱与理论方法结合的结合进行研究。Gold纳米颗粒在催化，分子电子和生物学中具有广泛的应用。 像Wang教授及其小组这样的仔细研究建立了这些物种的电子和化学特性的知识基础，这些知识基础有助于告知这些物质发挥作用的各种纳米技术领域。 接受Wang教授研究小组研究培训的学生将学习在独特的大学/国家实验室环境中使用复杂的设备。 王教授的黄金集群研究吸引了公共利益，王教授仍然是科学的出色大使。
