MRI: Acquisition of an X-ray Diffractometer

该奖项由主要研究仪器和化学仪器计划支持。来自加州大学滨江的William Harman教授和同事Vincent Lavallo正在购买一台配备钼源的单晶衍射仪。一般来说，X射线衍射仪允许准确和精确地测量分子的完整三维结构，包括键距和角度，并提供关于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。X射线实验室人员利用衍射仪为代表性不足的少数民族学生营造包容性氛围。此外，实验室在加强大学与当地高中和社区大学学生之间的关系方面发挥着重要作用。X射线设施还为邻近的主要为该地区服务的本科院校提供服务。该奖项旨在加强各级的研究和教育。该衍射仪用于探索氧化还原活性硼烷的小分子活化以及用于催化的碳硼烷基配体的研究。它还可用于研究具有碳硼烷电解质的高容量镁电池和用于研究烯烃复分解催化。 该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award is supported by the Major Research Instrumentation and the Chemistry Instrumentation Programs. Professor William Harman from the University of California Riverside and colleague Vincent Lavallo are acquiring a single crystal diffractometer equipped with a molybdenum source. 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 and biochemistry. The X-ray laboratory personnel utilize the diffractometer to foster an inclusive climate for underrepresented minority students. In addition, the laboratory plays an important role in strengthening the relationship between the University and local high school and community college students. The X-ray facility also provides service to neighboring primarily undergraduate institutions serving the region. The award is aimed at enhancing research and education at all levels. The diffractometer is used in the exploration of small molecule activation with redox-active boranes and in studies of carborane-based ligands for use in catalysis. It is also useful for investigating high capacity magnesium batteries having carborane electrolytes and for studying olefin metathesis catalysis. In addition, it is being utilized for the characterization of organometallic scandium complexes and metal-ligand assemblies.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.
