MRI: Acquisition of a Powder X-ray Diffractometer for Research and Teaching

凭借重大研究仪器（MRI）奖，纽约州立大学州立大学化学系将获得X射线粉末衍射仪系统。 这将被用于各种系统的研究，包括铋氧簇，超分子组装与多面体腔纳入卤素原子，富碳开放测地线polyarenes，异质dirhodium催化剂，有机硫和有机硒多螺配体，和量子点嵌入聚苯胺/Laponite薄膜。 X射线粉末衍射仪为研究人员提供了各种技术，如定性相鉴定和定量相分析，变温下的化学过程监测，薄膜分析，最重要的是，当单晶衍射无法使用时，直接确定晶体结构。 它特别适用于研究含有无序或不形成良好晶体的材料。新的粉末衍射仪器将影响课程和学生的培训。 由于X射线粉末衍射是法医应用的一个非常有吸引力的工具，它将支持法医设施，并加强法医化学学士学位的课程。℃下 该仪器将可用于联合学院和其他四年制学院、奥尔巴尼地区的几所专业学校和社区学院的研究和教学。

With a Major Research Instrumentation (MRI) award, the Department of Chemistry at the State University of New York-Albany will acquire an X-ray powder diffractometer system. This will be used in research on a variety of systems including bismuth oxy-clusters, supramolecular assemblies with polyhedral cavities incorporating halogen atoms, carbon-rich open geodesic polyarenes, heterogeneous dirhodium catalysts, organosulfur and organoselenium polyspiro ligands, and quantum dots embedded within polyaniline/Laponite films. An X-ray powder diffractometer gives researchers access to a variety of techniques such as qualitative phase identification and quantitative phase analysis, chemical process monitoring under variable temperatures, thin film analysis, and most importantly, direct crystal structure determination when single crystal diffraction cannot be used. It is especially useful for the study of materials that contain disorder or do not form good crystals. The new powder diffraction instrumentation will impact the curriculum and the training of students. Since X-ray powder diffraction is a very attractive tool for forensic applications, it will bolster the forensic facility and strengthen the curriculum for a forensic chemistry B.S. degree. The instrument will be available for use in research and teaching at Union College and other four year colleges, several professional schools and community colleges in the Albany area.
