Support of UIC single-crystal x-ray diffraction facilities

来自这笔赠款的资金将支持升级伊利诺伊大学芝加哥分校的单晶X射线衍射(XRD)能力。配备了CCD探测器的X射线衍射仪将取代地球与环境科学(E&Amp；ES)中陈旧的Picker仪器(1968年款)和化学中的诺尼乌斯衍射仪，并更新这些实验室的能力。该系统将允许进行现在不可能进行的研究，包括研究更小的晶体，减少搜索适合研究的单晶的时间，以及在高温实验期间快速收集数据，特别是在层状硅酸盐研究中。这些研究通常涉及具有大量缺陷的材料，在这些材料中，较小的微晶尺寸和减少搜索时间将提高生产率。此外，使用更小的晶体将允许在内部研究新材料。E&Amp；ES X射线实验室已成为芝加哥大都市区的一所主要大学和地区性设施。该设施的日常使用是由地球和环境科学系、化学、化学工程、牙科、土木工程、物理学和研究资源中心，以及来自大学以外的参观者。该系统将提供单晶能力，这将大大增加一组新的研究人员对该设施的使用。

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.***
