With support from the Chemistry Research Instrumentation and Facilities-Departmental Multiuser Instrument Acquisition (CRIF-MU) Program, the Department of Chemistry at Case Western Reserve University will acquire a single-crystal X-ray diffractometer with CCD detector and low temperature capability. Research projects that will be enhanced by this instrument includes studies on (a) the mechanism of amine oxidation catalyzed by the copper/quinine-dependent amine oxidases and the design of mechanism-based inactivators; b) modification of proteins by lipid and sugar oxidation products during oxidative stress; c) novel oligomeric and polymeric materials; d) characterization of nanosized aggregates that form at the outset of biomineralization; d) highly controlled asymmetric reactions; e) synthesis of new and unusual three-dimensional architectures; and f) properties of metal macrocycles. The X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and it provides accurate information about the spatial arrangement of the molecule relative to the neighboring molecules. These studies will have an impact in a number of areas, especially synthetic chemistry, materials science and biochemistry. In addition, the diffractometer will be cyber-enabled to allow access to users at remote locations.

在化学研究仪器和设施部门多用户仪器采购 (CRIF-MU) 计划的支持下，凯斯西储大学化学系将采购一台具有 CCD 探测器和低温功能的单晶 X 射线衍射仪。该仪器将加强的研究项目包括(a)铜/奎宁依赖性胺氧化酶催化胺氧化的机制以及基于机制的灭活剂的设计的研究； b) 氧化应激过程中脂质和糖氧化产物对蛋白质的修饰； c) 新型低聚物和聚合物材料； d) 生物矿化开始时形成的纳米级聚集体的表征； d) 高度受控的不对称反应； e）新的和不寻常的三维架构的综合； f) 金属大环化合物的性质。 X 射线衍射仪可以精确测量分子的完整三维结构，包括键距和角度，并提供有关分子相对于相邻分子的空间排列的准确信息。这些研究将在许多领域产生影响，特别是合成化学、材料科学和生物化学。 此外，衍射仪将通过网络启用，以允许远程位置的用户访问。
