Acquisition of a Powder X-ray Diffractometer

在化学研究仪器和设施（CRIF）计划的支持下，托莱多大学化学系将获得一台粉末x射线衍射仪。该设备将加强许多领域的研究，包括对a)负热膨胀材料的研究；B)薄膜电压；C)异质金属硫化物桥接团簇作为混合金属硫化物催化剂的前体；D)酶结构变化的微晶检查；e)结晶蛋白/DNA复合物分析。x射线衍射仪可以精确测量分子的完整三维结构，包括键的距离和角度，并提供分子相对于邻近分子的空间排列的准确信息。这些研究将对许多领域产生影响，特别是生物化学和材料科学。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Toledo will acquire a powder X-ray diffractometer. This equipment will enhance research in a number of areas including studies on a) negative thermal expansion materials; b) thin film voltaics; c) heterometallic sulfide-bridged clusters as precursors to mixed-metal sulfide catalysts; d) microcrystalline examination of enzymes structural changes; and e) analysis of crystalline protein/DNA complexes. 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 biochemistry and materials science.
