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.

该奖项由主要研究仪器（MRI）和化学研究仪器计划支持。来自哈维·穆德学院的杰拉尔德·货车·赫克教授和他的同事们正在购买一台差示扫描量热仪（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变化。 可以研究材料吸收热量的能力（热容）和多晶型晶体的检测。该仪器用于大气气溶胶研究和热能储存介质潜在材料的研究。DSC提供了在哈维穆德，姐妹克莱蒙学院，和至少两个地方社区学院，大大增加了年轻的研究人员在这项技术的培训量热法的研究机会。这种热量计加强了各级的研究和教育。它有助于研究人员在热表征含水大气气溶胶和探索简单的羧酸液体的二元混合物的共晶和近晶行为。 这些后来的材料在热能储存材料中具有潜在的用途。 最后，用DSC测定了室温以上磁-铁电晶体耦合材料的热性质和相性质。
