This project, in the Inorganic, Bioinorganic, and Organometallic Chemistry Program, is a continuation of Professor Kenneth J. Klabunde's studies at Kansas State University of applications of "free atoms" and small particles. Specific topics to be investigated include 1) the use of metal atoms to produce novel arenemetal complexes of novel ligands such as sigma- bonded silanes, 2) the reaction of Group 2 metal atoms with alkyl or aryl halides to produce clusters that conceptionally may be considered as a combination of an alkyl or aryl metal halide with a small number (1-3) of additional metal atoms, 3) combination of metal vapors of two elements to small bielement particles as metastable alloys or mixtures, and 4) generation of colloids by deposition of metal vapors into organic solvents and their applications in generating films of metals on polymeric substrates. Condensation of gaseous metal atoms is rapidly becoming an important method of generating new materials with many interesting and important technological applications. This project is concerned with the fundamental understanding of exactly how metal atoms combine together, and with other reactive species, to give materials with specific properties.

该项目在无机、生物无机和金属有机化学项目中，是堪萨斯州立大学教授Kenneth J.KLabunde对“自由原子”和小粒子应用的研究的继续。要研究的具体专题包括：1)使用金属原子产生新型配体的新型芳族金属络合物，如Sigma键合硅烷；2)第2族金属原子与烷基或芳基卤化物反应，产生概念上可被认为是烷基或芳基金属卤化物与少量(1-3)额外金属原子的组合；3)两种元素的金属蒸气与作为亚稳定合金或混合物的小双元素粒子的组合；以及4)通过将金属蒸气沉积到有机溶剂中生成胶体及其在在聚合物衬底上生成金属薄膜的应用。气体金属原子的凝聚正迅速成为产生新材料的一种重要方法，具有许多有趣和重要的技术应用。这个项目关注的是对金属原子如何结合在一起以及如何与其他活性物种结合以获得具有特定性质的材料的基本了解。
