MRI: Acquisition of Single Crystal X-ray Diffractometer to Support Undergraduate Research in Chemistry

该奖项由主要研究仪器项目和化学研究仪器项目支持。威斯康星大学Eau Claire分校正在购买一台台式单晶X射线衍射仪，以支持Deidra Gerlach教授和他的同事Jason Halfen。这种衍射仪允许在各种具有重要经济意义的领域进行研究，例如对促进制造业发展非常重要的催化。一般来说，X射线衍射仪可以准确和精确地测量分子的全部三维结构，包括键距离和角度。该仪器还提供了关于分子相对于邻居的空间排列的准确信息。即将进行的研究可能会影响许多领域，包括有机和无机化学、材料化学和生物化学。该仪器是该学院以及其他系化学和生物化学专业本科生教学、科研和培训不可或缺的一部分。由该仪器实现的科学具有影响社会的潜力。学生准备的化合物的结晶学研究将培养学生对研究事业的参与，并导致研究产品的频率和质量提高，包括学生合著的出版物和校外演示文稿。通过使内部结构测定成为例行公事，该仪器将为学生的发展和为高级课程和进入研究生课程做准备提供显著的推动。该仪器将通过为附近校园的研究人员提供结晶学支持，促进重大的外展和合作可能性，为正在进行的部门努力提供长期影响，以加强招聘和留住女性、低收入/第一代大学生和代表性不足群体的成员，以从事化学科学方面的课程作业和职业生涯，这是更广泛的机构重点的一部分，以招收和留住多样化、包容性的学生群体。尤其是结构变化对有机金属催化作用的影响。该仪器用于分析荧光团的构象和构型效应。此外，它还提供了关于亚苄基双环有机催化剂的信息。衍射仪也被用来研究维生素K循环的机制。这一奖项反映了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。

This award is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. The University of Wisconsin-Eau Claire is acquiring a benchtop, single-crystal X-ray diffractometer to support Professor Deidra Gerlach and colleague Jason Halfen. This diffractometer allows research in a variety of fields of significant economic importance such as catalysis which is important to advance manufacturing. 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. The instrument also provides accurate information about the spatial arrangement of a molecule relative to neighbors. The studies to be performed may 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 students in chemistry and biochemistry at this institution as well other departments. The science enabled by this instrument has the potential to impact society.Crystallographic studies of compounds prepared by students will foster students' engagement in the research enterprise and lead to an enhanced frequency and quality of research products, including student coauthored publications and extramural presentations. By making in-house structure determination routine, the instrument will provide a significant boost to student development and preparation for advanced coursework and entry into graduate programs. The instrument will promote significant outreach and collaborative possibilities by providing crystallographic support to the researchers of nearby campuses providing long-term impact on ongoing departmental efforts to enhance the recruitment and retention of women, low income/first generation college students, and members of underrepresented groups to pursue coursework and careers in the chemical sciences, part of a broader institutional emphasis to recruit and retain a diverse, inclusive student body.The award of the X-ray diffractometer is aimed at enhancing research and education at all levels. It especially impacts studies of effects of structural variation on organometallic catalysis. The instrumentation is used to analyze conformation and configuration effects of fluorophores. In addition, it provides information on benzylidenecamphore organocatalysts. The diffractometer is also used to study the mechanism of the Vitamin K cycle.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.
