This Major Research Instrumentation (MRI) award, jointly funded by the Division of Materials Research (DMR), and the Established Program to Stimulate Competitive Research (EPSCoR), supports the acquisition of a single crystal X-ray diffractometer system, which is central to several research projects at Western Kentucky University (WKU). In addition, collaboration with faculty at three other universities (California Baptist University, Lipscomb University, and the University of Findlay) expands and provides access to a wider group of personnel. This advanced equipment plays a crucial role in addressing fundamental inquiries in the fields of chemistry, physics, and geology that demand accurate and precise measurements of the three-dimensional structures of crystalline compounds and minerals. Further, it offers valuable training and research opportunities for undergraduate students at WKU, high school students at regional high schools, including Gatton Academy students who are gifted students pursuing their high school courses in a residential setting on the WKU campus.The system features a microfocus sealed-tube Mo source, a multi-axis goniometer with optical encoders and all axes within a sphere of less than 7 micrometers, a photon area detector supporting shutterless data collection, an air-cooled generator, and a low-temperature device for sample temperatures between 80 K and 400 K. The software suite provided with the system consists of a comprehensive suite of reliable routines for collecting and integrating frame data from single crystals and for solving, refining, displaying, and publishing structural results. Projects supported by this instrument advance the state of knowledge for 1) metal-oxo chemistry and photocatalysis on how to generate heme-like metal complexes and how to control their structures to control their photocatalysis; 2) metal-organic framework chemistry on how to tune their structures to gain desired photocatalytic or electrochemical properties, 3) organic molecular chemistry on solid-state packing styles of phenanthroimidazole-based derivatives, and how to synthesize perfluorinated fused-ring pyridazines, halogenated tricyclooctanes/tricyclodecanes, and amino acid analogs, 4) solid state chemistry on how to make metal oxides and double Perovskites, 5) types, distribution, and structures of rare minerals at Mammoth Cave National Park.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项由材料研究部（DMR）共同资助的主要研究工具（MRI）奖和既定的竞争研究计划（EPSCOR）支持获得单个Crystal X射线​​衍射仪系统，该系统对西肯塔基大学（WKU）的几项研究项目至关重要。此外，与其他三所大学（加利福尼亚浸信会，Lipscomb大学和Findlay大学）的教师合作扩展了，并提供了与更广泛的人员的访问权限。该先进的设备在解决化学，物理和地质学领域的基本询问中起着至关重要的作用，这些询问需要对晶体化合物和矿物质的三维结构进行准确和精确的测量。此外，它为WKU的本科生，区域高中的高中学生提供了宝贵的培训和研究机会无封闭数据收集，风冷发电机和用于样品温度在80 K至400 K之间的低温设备。该系统提供的软件套件包括一套全面的可靠例程，用于从单晶收集和集成框架数据以及用于求解，用于求解，精炼，展示，展示和出版结构结果。该仪器支持的项目推进了知识状态1）关于如何产生血红素样金属复合物以及如何控制其结构以控制其光催化的金属氧化学和光催化； 2）金属有机框架化学如何调整其结构以获得所需的光催化或电化学特性，3）基于稳态的衍生物的固态填料样式的有机分子化学，以及如何使完美的融合型型吡啶s酸和酸性酸性酸性旋转酸酯和酸性的酸性旋转酸酯和酸性酸性旋转酸酯和同步4）关于如何制造金属氧化物和双重钙壶的固态化学，5）猛mm洞洞穴国家公园的稀有矿物质的类型，分布和结构。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来获得支持的。
