With this award from the Major Research Instrumentation (MRI) Program, Professor Arnold Rheingold from University of California San Diego will upgrade an X-ray diffractometer with a high-flux, high-energy microfocus source and a new detector. The award will enhance research training and education at all levels, especially in areas such as (a) carbon dioxide-fixation chemistry, (b) designed protein synthesis, and (c) studies of post-synthetic metal-organic framework modification.An X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The high-flux, high-energy source will generate a high flux of X-ray that will allow studies of very small crystals or poorly diffracting crystalline materials. The studies described here will impact a number of areas, including organic and inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research not only at UC San Diego but many other neighboring universities and colleges.

加州大学圣地亚哥分校的Arnold Rheingold教授获得了重大研究仪器(MRI)计划颁发的这一奖项，他将升级一台X射线衍射仪，配备高通量、高能微聚焦源和新探测器。该奖项将加强所有层面的研究、培训和教育，特别是在以下领域：(A)二氧化碳固定化学，(B)设计的蛋白质合成，(C)合成后金属-有机骨架修饰的研究。X射线衍射仪可以准确和精确地测量分子的全部三维结构，包括键距离和角度，并提供关于分子相对于邻近分子的空间排列的准确信息。这种高通量、高能量的光源将产生高通量的X射线，这将使研究非常小的晶体或衍射较差的晶体材料成为可能。这里描述的研究将影响许多领域，包括有机化学和无机化学、材料化学和生物化学。该仪器不仅将成为加州大学圣地亚哥分校教学和研究不可或缺的一部分，还将成为邻近的许多大学和学院的教学和研究的组成部分。
