Thermal analysis instrumentation is used for a variety of types of experiments, including thermogravimetric analysis (TGA), differential thermal analysis (DTA), differential scanning calorimetery (DSC) and thermomechanical analysis (TMA). This instrumentation is used to determine physical or thermodynamic properties of materials in which heat is directly involved, such as boiling, freezing and solidification-point determinations, heat of fusion and heat of vaporization. In some cases thermal studies include measurment of weight changes of a system as a function of increasing temperature. The results of these types of analysis provide meaningful information and a deeper understanding of the effects of temperature changes on materials. Thermal methods are used in studying materials such as polymers and ceramics. This award from the Chemistry Research Instrumentation program will help the Department of Chemistry at the University of Michigan acquire a Thermal Analysis System. The system will be used in the following areas of research. "Synthesis and Characterization of New Fe/S and Fe/Mo/S Clusters as Structural Analogs for Metallo-protein Active Sites and of Binary Metal Sulfides" "Characterization of Organometallic Polymers and Surface Reaction by Thermal Analysis" "Thermal Analysis of Solid-State Intercalation Compounds" "Studies of Solid State Telluride Compounds" "Characterization of Nanometer-Sized Materials" "Characterization of New Heteroaromatic Materials Based on Cyanoimidazole"

热分析仪器用于各种类型的实验，包括热重分析(TGA)、差热分析(DTA)、差示扫描量热仪(DSC)和热机械分析(TMA)。该仪器用于测定直接与热有关的材料的物理或热力学性质，如沸点、凝固点和凝固点的测定、熔化热和汽化热。在某些情况下，热研究包括测量作为温度升高的函数的系统的重量变化。这些类型的分析结果提供了有意义的信息，并更深入地了解了温度变化对材料的影响。热方法用于研究聚合物和陶瓷等材料。化学研究仪器项目的这一奖项将帮助密歇根大学化学系获得热分析系统。该系统将用于以下领域的研究。作为金属蛋白活性中心和二元金属硫化物结构类似物的新型Fe/S和Fe/Mo/S簇合物的合成与表征热分析研究聚合物与表面反应“固体插层化合物的热分析“固态碲化物的研究”“纳米材料的表征”基于氰基咪唑的新型杂环材料的表征
