With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Arizona will acquire a powder and thin film X-ray diffractometer system. This equipment will enhance research in a number of areas including the following: a) small angle and wide angle X-ray scattering of molecule-based materials, e.g., rigid bilayer thickness films of phthalocyanines; b) characterization of metal ion imprinted polymers (MIPs) for high selectivities in separation of various metal ions; c) photoresponsive liquid crystals; d) nanocomposites from metallized or mineralized polymerized lipid phases; e) structure and function in protein film assemblies; f) laminate planar waveguides for surface spectroscopy and chemical sensing; g) dendrimers supported by hexanuclear metal clustsers; and h) metal cluster-supported porous solids.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.

通过化学研究工具和设施（CRIF）计划的奖项，亚利桑那大学的化学系将获得粉末和薄膜X射线衍射仪系统。该设备将增强许多领域的研究，包括以下各个方面：a）基于分子的材料的小角度和广角X射线散射，例如邻苯烷的刚性双层厚度膜； b）在各种金属离子分离时，金属离子印迹聚合物（MIP）的表征； c）光自动液晶体； d）来自金属或矿化聚合脂质相的纳米复合材料； e）蛋白质膜组件中的结构和功能； f）用于表面光谱和化学传感的层压平面波导； g）六核金属夹具支持的树突聚合物； h）金属簇支持的多孔固体。X射线衍射仪可以准确，精确地测量分子的整个三维结构，包括键距离和角度，并提供有关该分子相对于分子相对于分子相对于分子的空间排列的准确信息。相邻分子。
