With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Emory University will acquire an X-ray diffractometer with CCD detector. This equipment will enhance research studies in a number of areas including the following: 1) synthetic models of iron sites in biological systems; 2) crystal engineering as a model of biomineralization; 3) scaffold approach to enantiomerically-pure substituted heterocycles; 4) inorganic clusters and cluster derived materials for catalysis, medicine and environmentally benign processes; 5) complex organic ring systems; 6) studies of organic-nitrogen moieties as potential catalysts for denitrification of petroleum products; 7) atomic dispersion parameters analysis by variable temp X-ray diffraction; 8) synthetic organic chemistry of bioactive organic compounds; 9) cascade processes in synthetic organic chemistry; and 10) preparation of nanotubes using oligomers of substituted ethynlterpyridyl metal complexes. 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.

凭借化学研究仪器和设施（CRIF）计划的这一奖项，埃默里大学化学系将获得一台带CCD探测器的X射线衍射仪。该设备将加强以下领域的研究：1）生物系统中铁位点的合成模型; 2）作为生物矿化模型的晶体工程; 3）对映体纯取代杂环的支架方法; 4）用于催化、医学和环境友好过程的无机簇和簇衍生材料; 5）复杂的有机环系统; 6）作为石油产品脱氮的潜在催化剂的有机氮部分的研究; 7）通过变温X射线衍射的原子分散参数分析; 8）生物活性有机化合物的合成有机化学; 9）合成有机化学中的级联过程;和10）使用取代的乙炔基吡啶金属络合物的低聚物制备纳米管。 X射线衍射仪可以精确测量分子的完整三维结构，包括键距和角度，并提供有关分子相对于相邻分子的空间排列的准确信息。
