With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Northern Illinois University will acquire a powder X-ray diffractometer. This equipment will enhance research in a number of areas including the following: 1) characterization of thin films of magneto-resistant materials; 2) structure-property relationships of nanograin colossal magnetoresistant films by deposition of aqueousacetate solution (DAAS) technique; 3) identification of powder samples and thin films of intermetallic materials; 4) chemical modification of layered intermetallic materials as quantum well structures; 5) carborane compounds; 6) synthesis and characterization of metallacarboranes; 7) design and synthesis of chiral diaryldiselenides; and 8) characterization and use as asymmetric catalysts in reduction of prochiral radicals. 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. This instrument will have an impact on the research of four groups in the areas of materials science and synthetic chemistry. In addition, students will have hands-on access for research purposes and in the classroom setting.

在化学研究仪器（CRIF）计划的支持下，北伊利诺伊大学化学系将获得粉末X射线衍射仪。该设备将增强许多领域的研究，包括以下各个方面：1）表征耐磁材料的薄膜； 2）纳米质磁磁性膜通过水溶液溶液（DAAS）技术的结构范围关系； 3）鉴定粉末样品和金属间材料的薄膜； 4）将分层间材料作为量子井结构的化学修饰； 5）Carborane化合物； 6）金属岩的合成和表征； 7）手性日全二乙烯的设计和合成； 8）表征并用作降低培养基自由基的不对称催化剂。 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相邻分子的空间排列的准确信息。 该仪器将对材料科学和合成化学领域的四组研究产生影响。 此外，学生将在研究目的和课堂环境中进行动手访问。
