MRI: Acquisition of an X-ray Diffractometer at the University of Southern California

该奖项由主要研究仪器项目和化学研究仪器项目支持。南加州大学(USC)正在购买一台单晶X射线衍射仪，以支持特拉维斯·威廉姆斯教授和他的同事拉尔夫·海格斯。一般来说，X射线衍射仪可以准确和精确地测量分子的全部三维结构，包括键距离和角度。衍射仪还提供关于分子相对于邻近分子的空间排列的准确信息。这些研究可能会影响许多领域，包括有机化学和无机化学、材料化学和生物化学。该仪器是该机构在化学、生物化学和其他工程领域的本科生和研究生的教学和科研培训的组成部分。此外，衍射仪对南加州大学和区域合作伙伴的教学和培训、外展活动和本科生研究具有广泛的影响，这些合作伙伴主要是本科院校(PUI)。仪器采购是通过南加州大学联合教育项目的青年科学家计划和美国化学学会南加州分会激励不同的低收入高中生成为科学和工程领域的领导者和创新者的推广计划的重要组成部分。授予X射线衍射仪旨在加强各级研究和教育。仪器的收购影响了合成无机和有机材料的表征，以开发新的催化剂，以促进用于生物柴油生产、太阳能转换燃料技术和光伏发电的制造。该仪器还用于研究催化过程，以实现聚合物的可持续性。此外，衍射仪有利于探索与甲醇经济相关的有机氟化合物。该仪器还用于表征与生物化学相关的产品。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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 Research Instrumentation programs. The University of Southern California (USC) is acquiring a single crystal X-ray diffractometer to support Professor Travis Williams and colleague, Ralf Haiges. 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. A diffractometer also provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies may impact many 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, biochemistry and other engineering fields at this institution. In addition, the diffractometer has broad impact on teaching and training, outreach activities, and undergraduate research at USC and regional partners from primarily undergraduate institutions (PUIs). The instrument acquisition is an essential component of an outreach program inspiring diverse, low-income high school students to become leaders and innovators in science and engineering through the Young Scientists Program of the USC Joint Educational Project and the Southern California Section of the American Chemical Society.The award of the X-ray diffractometer is aimed at enhancing research and education at all levels. The instrument acquisition impacts the characterization of synthetic inorganic and organic materials to develop new catalysts to advance manufacturing used for biodiesel production, solar-to-fuel technologies, and photovoltaics. The instrumentation is also used for studying catalytic processes to enable polymer sustainability. In addition, the diffractometer benefits exploration of organofluorine compounds of relevance to the methanol economy. The instrument is also used to characterize products relevant to biological chemistry.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.
