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.

纽约州立大学奥尔巴尼分校化学系将获得一套x射线粉末衍射仪系统，并获得主要研究仪器（MRI）奖。这将用于各种系统的研究，包括铋氧团簇、含有卤素原子的多面体空腔的超分子组件、富碳的开放式测地聚烯烃、非均相镝催化剂、有机硫和有机硒多螺体配体，以及嵌入聚苯胺/拉脱土薄膜中的量子点。x射线粉末衍射仪为研究人员提供了多种技术，如定性相识别和定量相分析，变温度下的化学过程监测，薄膜分析，最重要的是，当单晶衍射不能使用时，直接确定晶体结构。它对研究无序或不能形成良好晶体的材料特别有用。新的粉末衍射仪器将对课程设置和学生的培养产生影响。由于x射线粉末衍射是一种非常有吸引力的法医应用工具，它将加强法医设施和加强法医化学学士学位课程。该仪器将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。
