This award to California State University-Long Beach is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs to support and improve research by professor Xianhui Bu from and colleagues Michael Schramm, Young-Seok Shon and Fangyuan Tian. The institution is acquiring a single crystal X-ray difffractometer (SCXRD). 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, and provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies described here impact many areas, including organic and inorganic chemistry, materials chemistry, geology and biochemistry. This instrument is an integral part of teaching as well as research and research training of undergraduate students in chemistry and biochemistry at this Hispanic Serving Institution as well as California State University Los Angeles. The instrumentation provides direct research experience for students in a variety of courses distributed in various departments and other neighboring universities. The award of the X-ray diffractometer is aimed at enhancing research and education at all levels. The science enabled by this instrument provides relevant societal benefits through the development of new materials to address energy production, new catalysts to improve the synthesis of commodity and industrial chemicals. The instrumentation is also used for studying amino-acid-based homochiral porous materials with zeolite-type frameworks and for developing acid-base stable metal-organic framework materials (MOFs). In addition, it benefits the exploration of mono and bisgold resorcinarenes as supramolecular catalysts and for investigating mechanisms of MOF catalysis based on structures of MOFs and trapped reaction intermediates (in collaboration with California State University Los Angeles). The diffractometer is also used to characterize fluorescent metal-organic frameworks for sensing explosive compounds. Additionally, the diffractometer is utilized for the structural characterization of non-heme iron nitrosyl complexes and catalysis made from monometallic palladium, platinum and iridium nanoclusters.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.

授予加州州立大学长滩分校的该奖项得到了重大研究仪器和化学研究仪器项目的​​支持，以支持和改进布贤惠教授及其同事 Michael Schramm、Young-Seok Shon 和 Fangyuan Tian 的研究。该机构正在购买一台单晶 X 射线衍射仪 (SCXRD)。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，并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许多领域，包括有机和无机化学、材料化学、地质学和生物化学。该仪器是该西班牙裔服务机构以及加州州立大学洛杉矶分校化学和生物化学本科生教学和研究培训的重要组成部分。该仪器为分布在各个院系和其他邻近大学的各种课程的学生提供直接的研究经验。 X射线衍射仪的获奖旨在加强各级研究和教育。该仪器所支持的科学通过开发新材料来解决能源生产问题，开发新催化剂来改善商品和工业化学品的合成，从而提供相关的社会效益。该仪器还用于研究具有沸石型骨架的基于氨基酸的纯手性多孔材料以及开发酸碱稳定的金属有机骨架材料（MOF）。此外，它有利于探索单和双金间苯二芳烃作为超分子催化剂，并有利于研究基于 MOF 结构和捕获反应中间体的 MOF 催化机制（与加州州立大学洛杉矶分校合作）。该衍射仪还用于表征荧光金属有机骨架，以检测爆炸性化合物。此外，该衍射仪还用于非血红素亚硝酰基铁配合物的结构表征以及由单金属钯、铂和铱纳米团簇制成的催化作用。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力和技术进行评估，认为值得支持。更广泛的影响审查标准。
