Equipment: MRI: Track 1 Acquisition of a Single Crystal X-Ray Diffractometer for Structure Determination of Molecules and Materials at Primarily Undergraduate Institutions

该重大研究仪器（MRI）奖由材料研究部（DMR）和刺激竞争性研究的既定计划（EPSCoR）共同资助，支持收购单晶X射线衍射仪系统，这是西肯塔基州大学（WKU）几个研究项目的核心。此外，与其他三所大学（加州浸会大学，利普斯科姆大学和芬德利大学）的教师合作扩大，并提供更广泛的人员群体。这种先进的设备在解决化学、物理和地质学领域的基本问题方面发挥着至关重要的作用，这些领域需要准确和精确地测量晶体化合物和矿物的三维结构。此外，它还为WKU的本科生，地区高中的高中生，包括Gatton Academy的学生提供了宝贵的培训和研究机会，这些学生是在WKU校园的住宅环境中学习高中课程的天才学生。该系统具有微焦点密封管Mo源，带光学编码器的多轴测角仪，所有轴都在小于7微米的球体内，支持无快门数据采集的光子区域探测器、空气冷却发生器和样品温度在80 K和400 K之间的低温装置。该系统提供的软件套件包括一套全面可靠的例程，用于收集和整合单晶的框架数据，以及求解、精炼、显示和发布结构结果。由该仪器支持的项目推进了以下方面的知识状态：1）金属-氧代化学和如何生成血红素样金属络合物以及如何控制其结构以控制其结构; 2）金属-有机骨架化学，关于如何调节它们的结构以获得期望的光催化或电化学性质，3）菲并咪唑类衍生物的固态堆积方式的有机分子化学，以及如何合成全氟稠环哒嗪、卤代三环辛烷/三环癸烷和氨基酸类似物，4）固态化学如何制造金属氧化物和双钙钛矿，5）猛犸洞国家公园稀有矿物的类型、分布和结构。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
