项目摘要

0129824GuggenheimFunds from this grant will support an upgrade to the single-crystal X-ray diffraction (XRD) capabilities of the University of Illinois at Chicago. A CCD detector equipped XRD will replace an aging Picker instrument (vintage 1968) in Earth and Environmental Sciences (E&ES) and a Nonius diffractometer in Chemistry, and updates the capabilities of these laboratories. The system will allow for research that is not now possible including study of much smaller crystals, a reduction in search time for single crystals suitable for study, and rapid data collection during high-temperature experiments, especially for phyllosilicate studies. These studies often involve materials with high numbers of defects, where smaller crystallite sizes and a reduction in search time will increase productivity. In addition, the use of smaller crystals will allow new materials to be studied in-house. The E&ES X-ray laboratory has served as a major university and regional facility in the Chicago metropolitan area. Routine use of the facility is made by the Departments of Earth and Environmental Sciences, Chemistry, Chemical Engineering, Dentistry, Civil Engineering, Physics, and the Research Resources Center, in addition to visitors from outside the University. The system will provide single crystal capabilities that will substantially increase usage of the facility by a new group of researchers.***

0129824古根海姆这笔赠款的资金将支持芝加哥伊利诺伊大学单晶 X 射线衍射 (XRD) 能力的升级。配备 CCD 探测器的 XRD 将取代地球与环境科学 (E&ES) 中老化的 Picker 仪器（1968 年生产）和化学中的 Nonius 衍射仪，并更新这些实验室的功能。该系统将允许进行现在不可能的研究，包括研究更小的晶体、减少适合研究的单晶体的搜索时间以及高温实验期间的快速数据收集，特别是对于页硅酸盐研究。这些研究通常涉及具有大量缺陷的材料，其中较小的晶粒尺寸和搜索时间的减少将提高生产率。此外，使用更小的晶体将允许在内部研究新材料。 E&ES X 射线实验室是芝加哥大都市区的一所主要大学和地区设施。除了来自大学以外的访客外，地球与环境科学系、化学系、化学工程系、牙科系、土木工程系、物理系和研究资源中心也定期使用该设施。该系统将提供单晶功能，这将大大增加新研究小组对该设施的使用。***
