MRI: Acquisition of a High Brilliance Dual-Source X-ray Diffractometer for Advanced Materials Research, Education, and Training in Western New York

该奖项由主要研究仪器和化学研究仪器计划共同支持。纽约-布法罗的州立大学正在购买一台具有高亮度微焦点Cu源和混合光子计数探测器的衍射仪，以支持Jason Benedict教授及其同事Timothy Cook、大卫莱西、珍妮特莫罗和马克斯韦哈特的研究。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，催化和材料化学。该仪器是该机构化学和生物化学本科生和研究生教学、研究和研究培训的组成部分。仪器的范围将包括现有的研究和教学计划在UB和一些与附近的机构（德尤维尔学院，圣博纳文图尔大学，和布法罗州立大学）的合作努力。该奖项旨在加强各级研究和教育。该仪器的研究重点是各种物质的研究和表征，包括光活性晶体材料，特别是金属有机框架（MOFs）和药物共晶体，确定自组装共面卟啉催化剂和光活性化合物的结构，表征含有抗生素接头的新MOFs和由火焰气溶胶反应器制备的高熵金属氧化物。研究人员还将探索用作磁共振成像（MRI）探针的顺磁性过渡金属络合物的结构，空气敏感有机金属催化剂的结构，特别是Mn和Ru络合物。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 jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. The State University of New York - Buffalo is acquiring a diffractometer with a high brilliance microfocus Cu source and a hybrid photon counting detector to support the research of Professor Jason Benedict and colleagues Timothy Cook, David Lacy, Janet Morrow, and Mark Swihart. 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, catalysis, and materials chemistry. 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. The reach of the instrumentation will include existing research and teaching programs at UB and some collaborative efforts with nearby institutions (D’Youville College, Saint Bonaventure University, and Buffalo State College).The award is aimed at enhancing research and education at all levels. Research enabled by the instrument is focused on the study and characterization of a wide variety of substances including photoactive crystalline materials especially in metal organic frameworks (MOFs) and in pharmaceutical co-crystals, determining the structure of self-assembled co-facial porphyrin catalysts and photoactive metallocages, characterization of new MOFs containing antibiotic linkers and high entropy metal oxides prepared by flame-based aerosol reactors. Researchers will also explore the structures of paramagnetic transition metal complexes used as magnetic resonance imaging (MRI) probes, the structures of air sensitive organometallic catalysts, especially Mn and Ru complexes.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.
