This award from the Chemistry Research Instrumentation and Facilities Program (CRIF) will assist the Department of Chemistry at Colorado State University in purchasing two powder X-ray diffraction systems that will complement each other as bulk powder analysis and thin film analysis instruments. The x-ray equipment will enhance research in a number of areas including the following: (1) rare earth Zintl materials, high pressure structural studies and thin film studies, (2) silicon based materials and polymerization, (3) conducting polymer nanostructures and nanostructures as secondary batteries, (4) Van der Waals epitaxy, electrochemical oxidation of superconductor thin films and epitaxial growth of chalcopyrite semiconductors, and (5) nonclassical metal carbonyls. The X-ray diffractometer is used to make accurate and precise measurements of the full three dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of the molecule relative to the neighboring molecules.

该奖项由化学研究仪器和设施 CRIF计划将协助科罗拉多州立大学化学系 大学购买两台粉末X射线衍射系统， 粉末分析与薄膜分析互为补充 仪器. X射线设备将加强对一些领域的研究， 主要包括以下几个方面：（1）稀土Zintl材料，高 压力结构研究和薄膜研究，（2）硅基 材料和聚合，（3）导电聚合物纳米结构， 纳米结构作为二次电池，（4）货车范德瓦尔斯外延， 超导薄膜的电化学氧化和外延 黄铜矿半导体的生长，和（5）非经典金属 羰基化合物 采用X射线衍射仪进行精密度和准确度测定， 分子的完整三维结构的测量。的 获得的信息给出了所有键距的精确值 和键角的关系，它能给出精确的信息 关于分子相对于相邻分子的空间排列 分子。
