This project provides a Peltier Thermoelectrically-Cooled Silicon Detector (TCD) system to support a Scintag 2000 x-ray diffraction (XRD) unit. The new instrumentation fills a recognized need to introduce XRD techniques in chemistry and to significantly increase the capabilities in geology. Courses immediately introduce and result in more and better hands-on use of XRD experiences and more sophisticated XRD laboratory exercises include Mineralogy, X-ray Crystallography, Independent Study, Physical Chemistry, Instrumental Analysis, and Inorganic Chemistry. Beyond this, the upgrade in instrumentation opens exciting new avenues for undergraduate research. The project continues to introduce XRD diffractometry in the sophomore (geology majors) and junior (chemistry majors) years followed by progressively more advanced real problem-solving experiences in the senior-level courses in both geology and chemistry. The impact of the instrumentation upgrade on instruction can be assessed by student evaluation and peer observation of assigned laboratory activities.

该项目提供了一个Peltier热电冷却硅探测器（TCD）系统，以支持Scintag 2000 X射线衍射（XRD）单元。 新仪器满足了在化学中引入XRD技术并显着提高地质学能力的公认需求。 课程立即引入并导致更多更好地实践使用XRD经验和更复杂的XRD实验室练习，包括矿物学，X射线晶体学，独立研究，物理化学，仪器分析和无机化学。 除此之外，仪器的升级为本科研究开辟了令人兴奋的新途径。 该项目继续在大二（地质专业）和大三（化学专业）引入XRD衍射法，然后在地质学和化学的高级课程中逐步引入更先进的真实的解决问题的经验。 仪器升级对教学的影响可以通过学生评价和同行观察指定的实验室活动来评估。
