MRI: Acquisition of a Single-Crystal Microsource Diffractometer for Interdisciplinary Materials Research and STEM Education

非技术性：通过与几个主要是本科机构、研究型大学、社区学院和当地高中的研究和教育合作，北佛罗里达大学(UNF)收购单晶X射线衍射仪预计将使整个佛罗里达东北部地区受益。该团队的研究项目跨越许多STEM学科，包括化学(无机/材料化学、有机/有机金属化学和化学教育)、凝聚态物理以及材料科学和工程的一般领域。这一工具的教学影响也是广泛的，因为它被纳入a)化学和物理本科课程(即高级实验室和各种本科研究项目)，b)面向普通公众和高中生的外联活动，以及c)联合国基金会校园内的教师教育活动。技术：单晶X射线衍射(SC-XRD)是化合物和固态材料的最终结构表征方法，提供有关键长和键角的信息以及分子和扩展系统的3D图像。对于固态材料，它探测缺失的键、结构变化和各向异性，这是理解/调整材料属性的重要信息。利用加压下的SC-X射线衍射仪研究了压力诱导的结构变化，并将其应用于材料的宏观后合成性能调控。因此，该团队使用SC-X射线衍射仪对a)磁性材料和相关材料、b)多铁材料、c)高温超导体、d)分子磁体和多核团簇、以及e)有机/有机金属化合物作为药物和催化剂进行跨学科研究。预计该仪器的微焦点X射线源和/或压强(50 Gpa)下的SC-X射线衍射仪将加强这些努力。在化学和物理课程中并通过本科生的研究将SC-XRD纳入课程，预计将丰富向联合国大学本科生提供的经验学习机会，并使他们接触到现代材料研究。这一设施预计将通过与至少三个主要本科机构和两所研究型大学的研究和教育合作，使整个佛罗里达州东北部受益。此外，在教师教育活动和对联合国基金会的实地考察中纳入SC-XRD，将使当地高中教师和学生接触尖端研究，并加强联合国基金会与社区的联系。

Non-technical: The acquisition of a single-crystal X-ray diffractometer at the University of North Florida (UNF) is expected to benefit the entire Northeast Florida region, through research and educational collaborations with several primarily undergraduate institutions, research universities, community colleges, and local high schools. The team's research projects span many STEM disciplines, including chemistry (inorganic/materials chemistry, organic/organometallic chemistry, and chemical education), condensed matter physics, and the general area of materials science and engineering. The pedagogical impact of this instrument is also extensive because of its incorporation in a) both the chemistry and physics undergraduate curricula (i.e. in advanced labs and in various undergraduate research projects), b) outreach activities both for the general public and for high school students, and c) teachers' education events on the UNF campus. Technical: Single-crystal X-ray diffraction (SC-XRD) is the ultimate structural characterization method for chemical compounds and solid-state materials, providing information about bond lengths and angles and the 3D picture of molecules and extended systems. For solid-state materials it probes missing bonds, structural changes, and anisotropy, which is important information for understanding/tweaking the materials' properties. Pressure-induced structural changes are probed with SC-XRD under pressure, with applications in macroscopic post-synthetic properties manipulation in materials. As such, the team uses SC-XRD in interdisciplinary investigations of a) magnetic and correlated materials, b) multiferroics, c) high temperature superconductors, d) molecular magnets and polynuclear clusters, and e) organic/organometallic compounds as drugs and catalysts. Enhancement of these efforts is expected from the microfocus x-ray source and/or the SC-XRD under pressure (50 GPa) capabilities of the instrument. Incorporation of SC-XRD in the chemistry and physics curricula and through undergraduate research is expected to enrich the experiential learning opportunities offered to UNF undergraduates and expose them to modern materials research. This facility is projected to benefit the entire Northeast Florida, through research and educational collaborations with at least three primarily undergraduate institutions and two research universities. Additionally, incorporation of SC-XRD in teachers' education events and field trips to UNF is poised to expose local high school teachers and students to cutting edge research and strengthen UNF's bonds to the community.
