Improvement of the Chemistry Advanced Laboratory Program Through the Addition of Differential Scanning Calorimetry

威斯敏斯特学院高级化学学生正在使用现代差示扫描量热计来研究各种材料的热化学性质。研究的样品范围广泛，包括聚合物，液晶，金属合金，以及学生自己的有机和无机合成项目的产品。学生（其中40%是女性）在研究凝聚态物质相变的物理性质时，正在获得这种常用测试方法的实践经验。每个学生在至少六个不同的项目中使用这些设备，从而获得了这项重要技术的操作和应用的非常全面的知识。实验室项目的出版将把这些活动的影响扩展到学院之外。

A modern differential scanning calorimeter is being used by upper level chemistry students at Westminster College to study the thermochemical properties of a variety of materials. The wide range of samples studied include polymers, liquid crystals, metal alloys, and the products from students' own organic and inorganic synthesis projects. Students (forty per cent of whom are women) are gaining hands-on experience with this common testing method while investigating the physical nature of phase changes in condensed matter. Each student uses the equipment in at least six different projects, thus gaining a very thorough knowledge of the operation and applications of this important technique. Publication of the laboratory projects will extend the impact of these activities beyond the college.
