该主要研究仪器奖支持扬斯敦州立大学获得高性能单晶x射线衍射系统，该系统针对最具挑战性的样品进行了结构表征优化。它配备了先进的Cu微聚焦源，多层光学器件，互补金属氧化物半导体（CMOS）面积探测器和kappa几何测角仪，以及可变温度系统。该仪器将极大地提高衍射数据的强度和分辨率，从非常小的和弱衍射晶体，许多具有大的单位细胞。网络支持的方法将允许非本地用户邮寄样品，然后在专家人员的实时支持下设计和执行自己的实验。它将有助于扩大主要由本科院校的学生和教师组成的远程用户群的研究和教育机会。新仪器将支持广泛的外部资助的材料科学和工程项目，特别是：(1)超分子，无机，半导体和金属材料的结构研究；(2)将先进的电子显微镜工具（例如，TEM/SEM，聚焦离子束，FIB和电子背散射衍射，EBSD）与衍射方法集成；(3)网络工具开发和晶体学教育；(4)与商业伙伴合作的研发企业。新仪器还将加强扬斯敦州立大学的教育和培训，支持该大学在本科和研究生阶段对材料科学与工程的新关注。******持续的进步使得单晶x射线衍射，SCD，越来越强大，快速，廉价，易于进行，经验丰富和新手用户。这种方法使化学家和材料科学家能够精确地确定材料的原子级结构，包括金属、半导体、无机-有机杂化化合物和多肽。然而，SCD需要获得必要的仪器和支持服务，这在绝大多数以本科院校为主的PUIs都没有。因此，该奖项将资助先进的单晶衍射仪，以支持材料科学和工程领域的广泛研究。杨斯敦州立大学，一个研究活跃的PUI，将成为新仪器的基地，也将通过网络启用的方法向广大用户群体开放。新的衍射仪将增加远程用户的可访问性，提高分析具有挑战性样品的能力，并改善对新手晶体学家的培训和支持。用户基础将主要来自全国的pui，这些pui培养了大多数本科和硕士学生，他们将继续完成博士课程，为我们的行业工作，并成为下一代中学和社区大学的教师。新仪器将集成到完善的STaRBURSTT@YSU固态结构设施中。

This Major Research Instrumentation Award supports Youngstown State University with the acquisition of a high performance single crystal X-ray diffraction system optimized for the structural characterization of the most challenging samples. It is equipped with an advanced Cu micro-focus source, multilayer optics, a complementary metal-oxide-semiconductor (CMOS) area detector and kappa geometry goniostat, and a variable temperature system. The instrument will dramatically improve the intensity and resolution of the diffraction data from very small and weakly diffracting crystals, many with large unit cells. Cyber-enabled methods will allow non-local users to mail samples and then design and execute their own experiments with real-time support from expert personnel. It will help broaden the research and educational opportunities for a remote user base comprised mainly of students and faculty from Predominantly Undergraduate Institutions. The new instrumentation will support a wide range of externally funded materials science and engineering projects, especially: (1) structural studies of supramolecular, inorganic, semiconductor, and metallic materials; (2) integration of advanced electron microscopy tools (e.g., TEM/SEM, focused ion beam, FIB, and electron backscatter diffraction, EBSD) with diffraction methods; (3) cyber-tools development and crystallography education; and (4) collaborative R&D ventures with commercial partners. The new instrument will also enhance education and training at Youngstown State, supporting the university's new focus in Materials Science and Engineering at the undergraduate and graduate level.******Continuing advances have made single crystal X-ray diffraction, SCD, increasingly powerful, fast, inexpensive, and easy to carry out for both experienced and novice users. This method allows chemists and materials scientists to determine the precise, atomic-level structures of materials including metals, semiconductors, hybrid inorganic-organic compounds, and polypeptides. However, SCD requires access to the requisite instrumentation and support services, neither of which is found at the vast majority of Predominantly Undergraduate Institutions, PUIs. As such, this award from the Major Instrumentation Program will fund an advanced single crystal diffractometer to support a broad range of research in materials science and engineering. Youngstown State University, a research-active PUI, will be the base for the new instrumentation, which will also be accessible to a large user group via cyber-enabled methods. The new diffractometer will allow increased accessibility for remote users, increased capability for analysis of challenging samples, and improved training and support for novice crystallographers. The user base will be largely drawn from the nation's PUIs, which prepare the majority of undergraduate and masters students who go on to complete Ph.D. programs, staff our industries, and become the next generation of secondary school and community college instructors. The new instrument will be integrated into the well-established STaRBURSTT@YSU solid-state structure facility.
