MRI: Acquisition of a Powder X-Ray Diffractometer

在主要研究仪器计划(MRI)的这一奖项和化学研究仪器计划(CRIF)的支持下，内华达州雷诺大学的Benjamin King教授和同事Ana de Bettencourt-Dias将获得一台X射线粉末衍射仪。通常，X射线衍射仪可以准确和精确地测量分子的完整三维结构，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。粉末衍射仪也可以进行成分分析。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、地质学和生物化学。该仪器将是教学以及研究和研究培训的组成部分，不仅在化学方面，而且在地质、工程和材料科学方面也是如此。此外，该仪器还将用于K-12地区学校的外联活动。该提议旨在加强所有各级的研究和教育，特别是在下列领域：(A)设计和合成Lewis碱衍生物金属有机骨架，以选择性地去除气体混合物中的二氧化碳；(B)研究用于催化还原二氧化碳的封顶、混合双金属体系；(C)开发用于DNA定点结合的单金属和双金属嵌入剂；(D)研究在光伏、光催化二氧化碳还原和光声成像技术中应用的分子体系；(E)研究铁和过氧化氢动态平衡的生物无机化学；和(F)制定制备复杂有机分子的战略。

With this award from the Major Research Instrumentation Program (MRI) and support from the Chemistry Research Instrumentation Program (CRIF), Professor Benjamin King from University of Nevada Reno and colleagues Ana de Bettencourt-Dias will acquire an X-ray-powder diffractometer. In general, 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. A powder diffractometer also allows compositional analysis. The studies described here will impact a number of areas, including organic and inorganic chemistry, materials chemistry, geology and biochemistry. This instrument will be an integral part of teaching as well as research and research training not only in Chemistry but also in Geology and Engineering and Materials Science. In addition, the instrument will be used in outreach activities involving K-12 area schools.The proposal is aimed at enhancing research and education at all levels, especially in areas such as (a) designing and synthesizing Lewis base derivatized metal-organic frameworks (MOFs) to selectively remove carbon dioxide from gaseous mixtures; (b) studying capped, mixed bimetallic systems for the catalytic reduction of carbon dioxide; (c) developing mono- and bi-metallo-intercalators for site specific binding of DNA; (d) investigating molecular systems for application in photovoltaics, photocatalytic carbon dioxide reduction and photoacoustic imaging technologies; (e) studying bioinorganic chemistry of iron and hydrogen peroxide homeostasis; and (f) developing strategies for the preparation of complex organic molecules.
