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.

该奖项得到了主要的研究工具（MRI）和化学研究工具（CRIF）计划的支持。北德克萨斯大学（UNT）和同事Michael Richmond，Francis d'Souza，Mohammad Omary和Hong Wang的同事Michael Richmond和Hong Wang的同事已获得了微型焦点X射线衍射仪。通常，X射线衍射仪可以准确，精确地测量分子的完整三维结构，包括键距和角度。 该仪器还提供了有关分子相对于相邻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。该乐器是UNT本科生教学和研究活动不可或缺的一部分。 来自德克萨斯女子大学，德克萨斯大学阿灵顿大学，奥斯汀学院和俄亥俄州迈阿密大学的化学和生物化学合作者也分享了该乐器的使用。衍射仪在各个层面上增强了研究和教育。这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光电材料，金属簇化学和有机材料和非对称催化剂的材料前体。衍射仪对金属复合物的结构测定和计算建模和代谢组学的小分子表征有益。研究。
