This award is supported by the Major Research Instrumentation and the Chemistry Instrumentation Programs. Professor Mercouri Kanatzidis from Northwestern University and colleagues Kenneth Poeppelmeier, Sossina Haile, Steven Jacobsen and Danna Freedman are acquiring a single crystal X-ray diffractometer equipped with a silver micro-source, goniometer, and an efficient detector optimized for silver-radiation. 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. 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 where students receive hands-on access to the diffractometers and collect data on their own experimental samples. The new diffractometer is also used for the biannual international Summer School co-organized with the American Crystallographic Association and Northwestern University. Collaborations are in place with other research institutions such as the University of Chicago, the Ohio State University, Illinois Institute of Technology, Loyola University Chicago, Lake Forest College and Roosevelt University. The award is aimed at enhancing research and education at all levels. It is especially used for exploring solid state chemistry of chalcogenides and analyzing solid-state-related electrochemical processes. The diffractometer is also utilized for the analyses of synthesized compounds and minerals as well as synthesized oxides and oxide-fluorides. The instrument is employed in projects with applications in sustainable energy, geology, planetary sciences, ceramics and nanomaterials.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.

该奖项得到了主要的研究工具和化学工具计划的支持。来自西北大学的Mercouri Kanatzidis教授和同事Kenneth Poeppelmeier，Sossina Haile，Steven Jacobsen和Danna Freedman正在购买配备银色微型，齿状仪和有效探测器的单晶X射线衍射仪。 通常，X射线衍射仪可以准确，精确地测量分子的完整三维结构，包括键距离和角度，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了许多领域，包括有机和无机化学，材料化学和生物化学。该乐器是该机构化学和生物化学的本科生和研究生的教学和研究培训的组成部分，在该机构中，学生可以动手访问衍射仪，并根据自己的实验样本收集数据。新的衍射仪还用于与美国晶体学协会和西北大学共同组织的双年度国际暑期学校。与其他研究机构进行合作，例如芝加哥大学，俄亥俄州立大学，伊利诺伊州理工学院，洛约拉大学芝加哥，芝加哥，森林学院和罗斯福大学。 该奖项旨在增强各级研究和教育。它特别用于探索葡萄干剂的固态化学和分析与固态相关的电化学过程。衍射仪还用于合成化合物和矿物质以及合成氧化物和氧化氟化物的分析。该工具用于具有可持续能源，地质，行星科学，陶瓷和纳米材料的项目中。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛影响的评估审查标准的评估来通过评估来支持的。
