With this award from the Chemistry Research Instrumentation and Facilities Multiuser Program (CRIF:MU), Professor Jacob W. Petrich and colleague Arkady Ellern from Iowa State University will upgrade and cyber-enable an X-ray CCD diffractometer. This instrument will support research by a large number of users that include chemistry professors Verkade, Sadow, Jeffries-EL, Bakac, and Fang as well as the broader Iowa State University research community. Research will include stereoselective transformations to develop new catalytic reactions useful in syntheses ranging from petrochemical through commodity and fine chemicals to pharmaceuticals, molecular magnetic materials and molecule based magnetism, new pi-conjugated organic materials, studies of chromium(V) which promise to shed light on the reduction process of chromate in chemical and biological systems and improved catalytic processes, including those used for the production of value-added products from soybean oil.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 the molecule relative to the neighboring molecules. The studies described here will impact a number of areas, including chemistry, materials chemistry, biochemistry and agricultural chemistry. This instrument will be an integral part of teaching as well as research.

凭借化学研究仪器和设施多用户计划（CRIF：MU）的这一奖项，Jacob W. Petrich和他的同事来自爱荷华州州立大学的Arkady Ellern将升级一台X射线CCD衍射仪，并使其具备网络功能。该仪器将支持大量用户的研究，包括化学教授Verkade，Sadow，Jeffries-EL，Bakac和Fang以及更广泛的爱荷华州州立大学研究社区。研究将包括立体选择性转化，以开发新的催化反应，用于从石油化工到商品和精细化学品到药物的合成，分子磁性材料和分子基磁性，新的π共轭有机材料，铬（V）的研究，有望揭示化学和生物系统中铬酸盐的还原过程和改进的催化过程，X射线衍射仪可以精确测量分子的完整三维结构，包括键距和键角，并提供分子相对于相邻分子的空间排列的准确信息。这里描述的研究将影响许多领域，包括化学，材料化学，生物化学和农业化学。该仪器将成为教学和研究的一个组成部分。
