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.

该主要研究仪器奖支持扬斯敦州立大学收购高性能单晶X射线衍射系统，该系统针对最具挑战性的样品的结构表征进行了优化。 它配备了先进的铜微焦点源，多层光学，互补金属氧化物半导体（CMOS）面积探测器和kappa几何角度仪，以及一个可变温度系统。该仪器将大大提高衍射数据的强度和分辨率，这些数据来自非常小和弱衍射的晶体，其中许多晶体具有大的晶胞。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。它将有助于扩大远程用户群的研究和教育机会，这些用户群主要由本科院校的学生和教师组成。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）先进电子显微镜工具的集成（例如，TEM/SEM、聚焦离子束、FIB和电子背散射衍射（EBSD）与衍射方法;（3）网络工具开发和晶体学教育;以及（4）与商业合作伙伴的合作研发企业。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。不断的进步使得单晶X射线衍射，SCD，越来越强大，快速，廉价，易于进行经验丰富的和新手用户。这种方法允许化学家和材料科学家确定材料的精确原子级结构，包括金属，半导体，混合无机-有机化合物和多肽。然而，SCD需要获得必要的仪器和支持服务，这两者都没有在绝大多数以本科为主的机构，PUI中找到。因此，来自主要仪器计划的这一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。研究活跃的PUI扬斯敦州立大学将成为新仪器的基地，该仪器也将通过网络支持的方法向大型用户群开放。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的样品的能力，并改善对新手晶体学家的培训和支持。用户群将主要来自全国的PUI，这些PUI为大多数继续完成博士学位的本科生和硕士生做准备。计划，工作人员我们的行业，并成为下一代的中学和社区大学讲师。新仪器将被集成到完善的STaRBURSTT@YSU固态结构设施中。
