Acquisition of Powder X-Ray Diffraction Instrumentation at Syracuse University

在化学研究仪器（CRIF）项目的支持下，雪城大学化学系将获得一台粉末x射线衍射仪。该设备将加强在许多领域的研究，如分子的结构和动力学以及材料的化学，包括金属氧化物、金属硼化物、金属硫属化合物、基于簇的纳米结构和扩展的金属有机pi系统等多种物种。其他将受益的项目包括水热反应固态产物的表征，薄膜样品的表征，以及从层状和开放式框架材料中去除溶剂和间隙或层间成分的产物的鉴定。具体来说，研究人员将使用该仪器对样品进行批量分析，确定温度相关的相变，确定聚合物的结晶度，并探索此类材料的首选取向。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。这些研究将在许多领域产生影响，特别是材料化学。该仪器还将用于雪城大学化学系和地球科学系的正式教学。

With support from the Chemistry Research Instrumentation (CRIF) Program, the Department of Chemistry at Syracuse University will acquire a powder X-ray diffractometer. This equipment will enhance research in a number of areas such as the structure and dynamics of molecules and the chemistry of materials, including species as diverse as metal oxides, metal borides, metal chalcogenides, cluster-based nanostructures and extended metal-organic pi-systems. Other projects which will benefit include the characterization of solid state products of hydrothermal reactions, the characterization of thin film samples, and the identification of the products from the removal of solvent and interstitial or interlamellar components from layered and open framework materials. Specifically, researchers will use the instrument to carry out bulk analyses of samples, identify temperature-dependent phase changes, identify the degree of crystallinity in polymers, and explore the preffered orientation of such materials.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 materials chemistry. The instrument will also be used for formal instruction in the Chemistry and Earth Sciences Departments at Syracuse University.
