This starter grant award of the Chemistry Division to Illinois State University supports the research of Professor Lisa F. Szczepura. The theme of the research is the investigation of the mechanism of ligand substitution of supraoctahedral transition metal clusters of the form (M'M6X8)n (where M' and M are transition metals and X = S, Se, or Te) that are important for understanding cluster reactivity. In particular, the effects of spectator ligands on the rates of ligand exchange will be examined. A second goal is the study of the redox reactivity of supraoctahedral clusters.The clusters studied in this project are part of a class of substances called Chevrel phase materials, which exhibit superconducting properties even in high magnetic fields. However, other applications include use as heterogeneous catalysts and as cathode materials in rechargeable lithium and lithium ion batteries. Studies of these types of clusters have a significant impact on the development of new lithium batteries with increased cycle life.

伊利诺伊州立大学化学部的启动资金支持 Lisa F. Szczepura 教授的研究。 该研究的主题是研究 (M'M6X8)n 形式的超八面体过渡金属簇的配体取代机制（其中 M' 和 M 是过渡金属，X = S、Se 或 Te），这对于理解簇反应性非常重要。 特别是，将检查观察配体对配体交换速率的影响。 第二个目标是研究超八面体团簇的氧化还原反应性。该项目中研究的团簇是一类称为 Chevrel 相材料的物质的一部分，即使在高磁场中也表现出超导特性。 然而，其他应用包括用作非均相催化剂以及用作可充电锂和锂离子电池中的阴极材料。 对这些类型簇的研究对开发具有更长循环寿命的新型锂电池具有重大影响。
