The project is integrating thermal analysis instrumentation into the curriculum of the Chemistry Department. Differential scanning calorimetry and thermogravimetric analysis are complementary techniques that provide unique and significant information about both the chemical reactions and the physical changes occurring in a sample. The instrumentation is being used in three upper-level chemistry courses, to allow students to experience its use as a quantitative analytical tool. It is also being used as a way to obtain data on physical changes, such as glass transition temperatures in polymers, that are difficult to obtain by other means. This instrumentation is being used to perform experiments that connect the field of chemistry to other closely related sciences, such as materials science, polymer science, and biology. It is familiarizing students with a technique that is not commonly included in the undergraduate curriculum, but is frequently used in commercial and industrial laboratories, particularly those that deal with materials-related problems. Thermal analysis instrumentation provides additional experience to students in the characterization of compounds, which is complementary to the microscale techniques already used.

该项目正在将热分析仪器纳入化学系的课程中。差示扫描量热法和热重分析是互补的技术，可提供有关样品中发生的化学反应和物理变化的独特且重要的信息。该仪器正在三门高级化学课程中使用，让学生体验其作为定量分析工具的用途。 它还被用作获取物理变化数据的一种方式，例如聚合物的玻璃化转变温度，而这些数据很难通过其他方式获得。 该仪器用于执行将化学领域与其他密切相关的科学（例如材料科学、聚合物科学和生物学）联系起来的实验。 它让学生熟悉一种通常不包含在本科课程中的技术，但在商业和工业实验室中经常使用，特别是那些处理材料相关问题的实验室。 热分析仪器为学生提供了化合物表征方面的额外经验，这是对已使用的微尺度技术的补充。
