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，生物促和有机金属化学计划中，是堪萨斯州立大学应用“自由原子”和小颗粒的肯尼斯·J·克拉本德教授的延续。 要研究的特定主题包括1）使用金属原子在新型配体（例如sigma键合的硅）中产生新型的舞台复合物，2）2）第2组金属原子与烷基或芳基卤化物的反应在概念上可以被视为含烷基或芳基金属的组合（三个金属）（1-3的金属）的组合，从而将其视为概念上的簇，这是一种组合。小的生物元颗粒作为亚稳 - 合金或混合物，以及4）通过将金属蒸气沉积到有机溶剂中及其在聚合物底物上生成金属膜时的应用。 气态金属原子的凝结正迅速成为具有许多有趣且重要的技术应用的新材料的重要方法。 该项目涉及对金属原子如何结合在一起以及与其他反应性物种的基本理解，以提供具有特定特性的材料。
