With this award from the Major Research Instrumentation Program (MRI) and support from the Chemistry Research Instrumentation Program (CRIF), Professor William Connick from the University of Cincinnati and colleagues Anna Gudmundsdottir, Jeanette Krause, James Mack II and Hairong Guan have acquired a dual source, microfocus single crystal X-ray diffractometer equipped with a photon detector and a cryogenic device. 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. It also provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies described here impact a number of areas, including organic and inorganic chemistry, materials chemistry and biochemistry. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution and regional collaborators. Additionally, the instrument exposes high school and undergraduate students to crystallography and research. Participation of underrepresented groups is enhanced through the principal investigator's involvement with ACS-Project SEED, Dreyfus, NSF-REU and Women in Science and Engineering programs. The award is aimed at enhancing research and education at all levels, especially in areas such as (a) identifying efficient photoprocesses for storing energy via metal-complex photochemistry that releases two electrons per photon absorbed, (b) studying sensor materials to determine the mechanisms of colorimetric and luminescence-based responses of materials to chemical vapors and aqueous ions, (c) preparing and characterizing potential catalysts for chemical transformations and green technologies and (d) characterizing the underlying chemistry of agents that release reactive species that target specific substrates or are themselves components in metabolic pathways or nanostructured materials.

凭借重大研究仪器计划 (MRI) 的奖项和化学研究仪器计划 (CRIF) 的支持，辛辛那提大学的 William Connick 教授及其同事 Anna Gudmundsdottir、Jeanette Krause、James Mack II 和 Hairongguan 获得了一台配备光子探测器和低温装置的双源微焦点单晶 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，包括键距和角度。 它还提供有关分子相对于相邻分子的空间排列的准确信息。这里描述的研究影响了许多领域，包括有机和无机化学、材料化学和生物化学。该仪器是该机构和区域合作者化学和生物化学本科生和研究生教学以及研究和研究培训的组成部分。此外，该仪器还让高中生和本科生接触晶体学和研究。通过首席研究员参与 ACS-Project SEED、Dreyfus、NSF-REU 和女性科学与工程项目，增强了代表性不足群体的参与。该奖项旨在加强各个层面的研究和教育，特别是在以下领域：(a) 确定通过金属络合物光化学存储能量的有效光处理，每个吸收的光子释放两个电子；(b) 研究传感器材料，以确定材料对化学蒸气和水离子的比色和发光响应机制；(c) 制备和表征化学转化的潜在催化剂，以及 绿色技术和（d）表征释放针对特定底物的活性物质或其本身是代谢途径或纳米结构材料中的成分的试剂的基本化学特性。
