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.

该奖项由主要研究仪器和化学仪器项目支持。西北大学的Merouri Kanatzidis教授及其同事Kenneth Poeppelmeier、Sossina Haile、Steven Jacobsen和Danna Freedman正在获得一台单晶X射线衍射仪，该衍射仪配备了一个银微光源、测角仪和一个针对银辐射进行了优化的高效探测器。通常，X射线衍射仪可以准确和精确地测量分子的完整三维结构，包括键距离和角度，并提供关于分子相对于邻近分子的空间排列的准确信息。这里描述的研究影响到许多领域，包括有机化学和无机化学、材料化学和生物化学。该仪器是本校化学和生物化学专业本科生和研究生教学、科研和培训不可或缺的一部分，学生可以在这里亲手接触衍射仪并收集他们自己的实验样品的数据。新的衍射仪还用于与美国晶体学会和西北大学联合举办的一年两次的国际暑期学校。与芝加哥大学、俄亥俄州立大学、伊利诺伊理工学院、芝加哥洛约拉大学、莱克森林学院和罗斯福大学等其他研究机构也进行了合作。该奖项旨在加强各级的研究和教育。它特别适用于探索硫系化合物的固态化学和分析与固态有关的电化学过程。该衍射仪还可用于合成化合物和矿物以及合成氧化物和氧化物氟化物的分析。该仪器用于可持续能源、地质学、行星科学、陶瓷和纳米材料的应用项目。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。
