MRI: Acquisition of a differential scanning calorimeter for undergraduate research and training

该奖项由主要研究仪器(MRI)和化学研究仪器计划支持。哈维马德学院的杰拉尔德·范·赫克教授和他的同事们正在研制一种差示扫描量热仪(DSC)。差示扫描量热计测量材料经历相变(例如从固体到液体)的温度、促进相变所需的热量以及玻璃温度的变化。可以研究材料的吸热能力(热容)和多晶型晶体的检测。该仪器用于大气气溶胶研究和潜在储能介质材料的研究。DSC在哈维穆德学院、克莱蒙特姐妹学院和至少两所当地社区学院提供量热方面的研究机会，这极大地增加了年轻研究人员在这项技术方面的培训。这种量热计加强了各级的研究和教育。它帮助研究人员对含水大气气溶胶进行热学表征，并探索简单羧基液体二元混合物中的共晶和包晶行为。这些新材料在热能储存材料中具有潜在的用途。最后，用差示扫描量热法测定了室温以上磁性与铁电晶体特性耦合的应急材料的热性质和相性质。

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation Programs. Professor Gerald Van Hecke from Harvey Mudd College and colleagues are acquiring a differential scanning calorimeter (DSC). A differential scanning calorimeter measures the temperature that a material undergoes a change in phase (for example from solid to liquid), the heat necessary to promote the phase change, and glass temperature changes. The capacity of a material to adsorb heat (heat capacity) and the detection of polymorphic crystals can be studied. The instrument is used in research on atmospheric aerosols and the study of potential materials for thermal energy storage media. The DSC provides research opportunities in calorimetry at Harvey Mudd, sister Claremont Colleges, and at least two local community colleges which greatly increases the training of young researchers in this technique. This calorimeter enhances research and education at all levels. It aids researchers in thermally characterizing aqueous atmospheric aerosols and in exploring eutectic and peritectic behavior in binary mixtures of simple carboxylic liquids. These later materials have potential use in thermal energy storage materials. Finally, the DSC is used to determine the thermal and phase properties of emergent materials for coupling magnetism to ferroelectric crystalline propwerties above ambient temperature.
