This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation (CRIF) Programs. Professor LeGrande Slaughter from the University of North Texas (UNT) and colleagues Michael Richmond, Francis D'Souza, Mohammad Omary and Hong Wang have acquired a microfocus X-ray diffractometer. In general, an X-ray diffractometer allows accurate and precise measurements of the full three-dimensional structure of a molecule, including bond distances and angles. The instrument also provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The research efforts may impact many areas, including organic and inorganic chemistry, materials chemistry and biochemistry. This instrument is an integral part of the teaching and research activities of undergraduate students at UNT. Collaborators in chemistry and biochemistry from regional institutions such as the Texas Woman's University, University of Texas at Arlington, Austin College and Miami University of Ohio also share use of the instrument.The diffractometer enhances research and education at all levels. It may impacts research on noncovalent influences on catalyst selectivity, artificial photosynthesis, and excitonic solar cells. The instrumentation is also used to investigate multifunctional metal-organic optoelectronic materials, metal cluster chemistry, and materials precursors to organic materials and asymmetric catalysts. The diffractometer benefits research on the structural determinations and computational modeling of metal complexes and small molecule characterization for metabolomics. studies.

该奖项由主要研究仪器（MRI）和化学研究仪器（CRIF）计划支持。来自北德克萨斯大学（UNT）的LeGrande Slaughter教授及其同事Michael里士满、弗朗西斯D 'Souza、Mohammad Omary和Hong Wang获得了一台微焦点X射线衍射仪。一般来说，X射线衍射仪可以精确测量分子的完整三维结构，包括键距和键角。 该仪器还提供有关分子相对于邻近分子的空间排列的准确信息。研究工作可能会影响许多领域，包括有机和无机化学，材料化学和生物化学。该仪器是UNT本科生教学和研究活动的一个组成部分。 来自德克萨斯女子大学、德克萨斯大学阿灵顿分校、奥斯汀学院和俄亥俄州的迈阿密大学等地区机构的化学和生物化学合作者也分享了该仪器的使用。它可能会影响对催化剂选择性、人工光合作用和激子太阳能电池的非共价影响的研究。该仪器还用于研究多功能金属有机光电材料，金属簇化学，以及有机材料和不对称催化剂的材料前体。衍射仪有利于金属配合物的结构测定和计算建模以及代谢组学的小分子表征研究。问题研究
