Non-Technical SummaryThis Major Research Instrumentation (MRI) award, jointly funded by the Division of Materials Research and the Established Program to Stimulate Competitive Research (EPSCoR), will acquire a new thermal characterization system which will allow the Physics Department at Coe College to measure various properties that depend on temperature up to very high values. The scientists will be able to look at the behavior of samples as the temperature is increased up to 2000 degrees Celsius. More specifically, they will conduct experiments on glasses that are extremely difficult to make. They will also measure thermal properties like melting points, crystallization temperatures, and the glass transition temperature (where the glass begins to soften). The system will also allow for the measurement of mechanical properties. These determine how easily a glass stretches as the temperature increases (thermal expansion coefficient), as well as volume and density changes. More advanced experiments that determine properties like the sintering temperature (where glass grains coalesce into a solid) will also be possible. These measurements are critical to understanding state-of-the-art new glasses and ceramic materials of future importance to the US economy. The work will also allow for the training of many undergraduate students. On top of carrying out the research described above, they will also be exposed to the instruments in certain advanced classes. International collaborators will also have access to the equipment during their visits to Coe.Technical SummaryThe new thermal characterization system at Coe College will be composed of a Simultaneous Thermal Analyzer (which runs differential scanning calorimetry (DSC), differential thermal analysis (DTA), and Thermogravimetric analysis (TGA)) and a ThermoMechanical Analyzer (TMA). This suite of tools will enable various Coe research groups to expand their measurement capabilities into the high-temperature range, with DSC/DTA measurements up to 2000 °C and 1600 °C for the mechanical (TMA) experiments. Projects will span from measurements on aerolevitated samples to comparisons between the results on invert glasses and topological constrain theory (TCT) models. The thermal properties of ionically conducting glasses will also be studied. The STA+TMA system will add substantive new capabilities to the materials research groups at Coe College; allow for the training of over 70 undergraduate students, and continue the growth of Coe College as a regional materials characterization hub. In turn, the characterization work on the system will impact other local academic institutions and companies, domestic and international collaborators; REU students; and high school teachers participating in Coe’s RET program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要这一主要研究仪器（MRI）奖，由材料研究部和刺激竞争性研究的既定计划共同资助（EPSCOR），将获得一个新的热表征系统，该系统将允许COE学院的物理部门衡量依赖温度值高至非常高的多种属性。随着温度升高到2000摄氏度，科学家将能够查看样品的行为。更具体地说，他们将对极其难以制作的眼镜进行实验。它们还将测量熔点，结晶温度和玻璃过渡温度（玻璃开始变软），例如熔点，结晶温度和玻璃过渡温度。该系统还将允许测量机械性能。这些确定玻璃随温度升高（热）的容易程度。扩展系数）以及体积和密度变化。也可以实现更先进的实验，以确定诸如烧结温度（玻璃谷物结合成固体）之类的特性。这些测量对于理解最先进的新眼镜和对美国经济重要性的陶瓷材料至关重要。这项工作还可以训练许多本科生。除了进行上述研究之外，它们还将接触到某些高级班级的工具。国际合作者还将在访问COE期间访问设备。技术总结，COE学院的新型热特性系统将由同时的热分析仪（运行差分扫描量热法（DSC），差分热分析（DTA）和热力计分析（TGA）（TGA）和热力学分析仪（TMANEMANICE）（TMANEMISILIS）（TMA）（TMA）。这套工具将使各种COE研究组能够将其测量能力扩展到高温范围内，DSC/DTA测量最高为2000°C和1600°C，用于机械（TMA）实验。项目将涵盖对空事样品的测量，到反转眼镜上的结果与拓扑约束理论（TCT）模型之间的比较。离子导电玻璃的热性能也将进行研究。 STA+TMA系统将为COE学院的材料研究小组增加实质性的新功能；允许对70多名本科生进行培训，并继续将COE学院作为区域材料表征中心的增长。反过来，该系统的表征工作将影响其他地方学术机构和公司，国内和国际合作者； REU学生；以及参加COE RET计划的高中教师。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估诚实的支持。
