This award is supported by the Major Research Instrumentation (MRI) Program, the Chemistry Research Instrumentation Program and the Experimental Program to Stimulate Competitive Research (EPSCoR). Professor George Richter-Addo from the University of Oklahoma and colleagues Daniel Glatzhofer, Robert Cichewicz, Indrajeet Sharma and Bayrammurad Saparov are acquiring a single crystal X-ray diffractometer. X-ray diffraction is a powerful tool to investigate the atomic structure of solid materials. It is used to understand how the atoms are arranged and bonded to each other in a material. The knowledge of the atomic structures of materials is fundamental to understanding their properties and developing improvements. The applications of microscopic structural knowledge ranges from chemistry to biology, materials and medicine, to applications such as developing better agrochemicals, electronic devices or pharmaceuticals. The instrument advances the training of students in research and is also employed in the annual Sooner Upward Bound program each summer that brings in inner-city (OKC) high school students at high risk for academic failure. This acquisition also assists research and training at five other partner Oklahoma institutions: Oklahoma State University, Northeastern State University, Southeastern State University, University of Science and Arts and Southwestern Oklahoma State University.This diffractometer advances research and education at the University of Oklahoma and surrounding area. It helps in identifying reactive molecular-level, metallo-intermediates in the global nitrogen cycle and developing new families of semiconductor materials and photovoltaics. The instrumentation is also used to characterize intermediates for organic transformations and applications in asymmetric synthesis. Researchers are developing semi- and total-synthesis methodologies and determining the absolute stereochemistry of natural products. This diffractometer is essential to determine the crystal structures of solid-state metal oxides/sulfides and organoactinide complexes.

该奖项由主要研究仪器（MRI）计划、化学研究仪器计划和刺激竞争性研究的实验计划（EPSCoR）支持。俄克拉荷马大学的George Richter-Addo教授和他的同事Daniel Glatzhofer、Robert Cichewicz、Indrajeet Sharma和Bayrammurad Saparov正在研制一台单晶x射线衍射仪。x射线衍射是研究固体材料原子结构的有力工具。它被用来了解物质中原子是如何排列和相互结合的。材料的原子结构的知识是了解其性质和发展改进的基础。微观结构知识的应用范围从化学到生物学、材料和医学，到开发更好的农用化学品、电子设备或药物等应用。该仪器促进了学生在研究方面的培训，也被用于每年夏天的“更快的向上发展”计划，该计划将市中心（OKC）高中的学生带到学业失败的高风险中。此次收购还有助于俄克拉荷马州其他五个合作机构的研究和培训：俄克拉荷马州立大学、东北州立大学、东南州立大学、科学与艺术大学和西南俄克拉荷马州立大学。这种衍射仪促进了俄克拉何马大学和周边地区的研究和教育。它有助于在全球氮循环中识别反应分子水平的金属中间体，并开发新的半导体材料和光伏家族。该仪器还用于表征有机转化的中间体和不对称合成中的应用。研究人员正在开发半合成和全合成方法，并确定天然产物的绝对立体化学。这种衍射仪是必不可少的，以确定固体金属氧化物/硫化物和有机锕系配合物的晶体结构。
