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首发赠款奖支持Lisa F. Szczepura教授的研究。 这项研究的主题是研究形式（M'M6x8）N（M'M'和M是过渡金属，X = S，SE或TE）的配体替换的机理，对于理解群集反应性很重要。 特别是，将检查观众配体对配体交换速率的影响。 第二个目标是研究上截面簇的氧化还原反应性。该项目中研究的簇是一类称为雪佛兰相材料的物质的一部分，即使在高磁场中，它们也具有超导性能。 但是，其他应用包括用作异质催化剂和可充电锂和锂离子电池中的阴极材料。 对这些类型的簇的研究对随着周期寿命的增加而对新锂电池的发展产生了重大影响。
