This application is for a Simultaneous Thermal Analyzer, an instrument that couples two fundamental methods in thermal analysis, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). DSC tracks any endothermic or exothermic phenomenon (i.e., any changes to the sample) as a function of heating. This includes glass transitions, melting, bond forming or breaking, vaporisation, etc. It measures precisely the energy needed to be added or removed to keep the sample and a reference pan at the same temperature. Thermogravimetric analysis measures sample mass as a function of heating. Minimally, it will tell the amount of volatiles lost at a specific temperature or decomposition. This allows accurate determination of sample composition via correlating with elemental analysis. Both DSC and TGA can be carried out in different atmospheres. For TGA, this can be very insightful as the instrument can also ascertain mass gain in addition to mass loss, including adsorption of carbon dioxide by porous solids. Two research programs are applying. The first team makes new porous solids and studies their applications including carbon capture, proton conduction, and separations. The thermal analysis methods are first steps to understand the conditions under which pores are occupied or voided by molecules. The second program studies the interactions of metal complexes with biomolecules. This requires precise understanding of the molecules bound to the metals to determine exact formulations. The thermal analysis methods provide key insights to what is bonded to the complexes.

此应用程序是一个同步热分析仪，仪器耦合热分析，差示扫描量热法（DSC）和热重分析（TGA）的两个基本方法。DSC跟踪任何吸热或放热现象（即，样品的任何变化）作为加热的函数。这包括玻璃化转变、熔化、键形成或断裂、蒸发等。它精确测量为保持样品和参比盘处于相同温度而需要添加或去除的能量。热重分析测量作为加热的函数的样品质量。最低限度，它将告诉在特定温度或分解时挥发物的损失量。这允许通过与元素分析相关联来准确测定样品组成。DSC和TGA都可以在不同的气氛中进行。对于TGA，这可以是非常有见地的，因为该仪器还可以确定除了质量损失之外的质量增加，包括多孔固体对二氧化碳的吸附。两个研究项目正在申请中。第一个团队制造了新的多孔固体并研究其应用，包括碳捕获、质子传导和分离。热分析方法是了解分子占据或空隙化孔隙的条件的第一步。第二个项目研究金属配合物与生物分子的相互作用。这需要精确了解与金属结合的分子，以确定确切的配方。热分析方法提供了关键的见解是什么键合到复合物。
