MRI: Acquisition of an X-ray Diffractometer for Research, Education, and Regional Use

该奖项由主要研究仪器（MRI）和化学仪器（CRIF）计划资助。 来自德克萨斯大学埃尔帕索分校（UTEP）的Skye Fortier教授和同事Tatiana Eugeeva（新墨西哥州高地大学）、Luis Echegoyen（UTEP）、Dino比利亚格兰（UTEP）和Erik Yukl（新墨西哥州州立大学）获得了一台单晶X射线衍射仪。 X射线衍射仪可以精确测量分子的完整三维结构。 这种结构包括键距和键角。 该仪器提供了关于分子相对于相邻分子的空间排列的准确信息。 这项研究可能会影响许多领域，包括有机和无机化学和生物化学。 在一个项目中，正在研究一种土壤细菌，它是一种DNA蛋白质修复物种。 确定了对海洋生态系统有贡献的海洋病毒的结构。衍射仪是一种多用户、多机构仪器，可满足整个地区研究机构和本科生项目的需求。除了UTEP，衍射仪还被新墨西哥州州立大学（NMSU）、新墨西哥州高地大学（NMHU）、安吉洛州立大学和福特。刘易斯学院。该仪器为研究生和本科生提供了培训机会。该衍射仪的购买增强了UTEP和周边机构研究生和本科生的研究和教育。 研究了在高度还原的金属配合物中氧化还原电荷的位置。铀内嵌富勒烯具有非凡的键合图案的特点。另一个正在调查的领域是一种重要的巨型海洋病毒的病毒组装。 新的单晶多铁性和硫属二维（2D）材料的特点是使用衍射仪。参与环境氧化还原传感的细菌蛋白质的结构正在确定中。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 funded by the Major Research Instrumentation (MRI) and Chemical Instrumentation (CRIF) programs. Professor Skye Fortier from University of Texas El Paso (UTEP) and colleagues Tatiana Timofeeva (New Mexico Highlands University), Luis Echegoyen (UTEP), Dino Villagran (UTEP), and Erik Yukl (New Mexico State University) have acquired a single crystal X-ray diffractometer. An X-ray diffractometer allows accurate and precise measurements of the full three-dimensional structure of a molecule. This structure includes bond distances and angles. This instrument provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The research may impact many areas, including organic and inorganic chemistry and biochemistry. In one project, a soil bacterium which is a DNA protein repair species is under investigation. The structure of marine viruses which contribute to the marine ecosystem are determined. The diffractometer is a multi-user, multi-institutional instrument that serves the needs of research institutions and undergraduate programs throughout the region. Besides UTEP, the diffractometer is used by New Mexico State University (NMSU), New Mexico Highlands University (NMHU), Angelo State University, and Ft. Lewis College. The instrument provides training opportunities to students at both the graduate and undergraduate levels.The acquisition of this diffractometer enhances the research and education of graduate and undergraduate students at UTEP and surrounding institutions. Investigations to identify the locus of redox charges in highly-reduced metal complexes are conducted. Uranium endohedral fullerenes with extraordinary bonding motifs are characterized. Another area under investigation is the viral assembly of an important giant marine virus. New single crystal multiferroics and chalcogenide two-dimensional (2D) materials are characterized using the diffractometer. The structure of bacterial proteins involved in environmental redox sensing is being determined. Synthesis and catalysis studies of molybdenum complexes that model molybdoenzyme active sites are also supported.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.
