Purchase of a Cyber-enabled X-Ray Microdiffractometer for the NYC Region

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。根据化学研究仪器和设施多用户计划（CRIF:MU）的奖励，来自纽约大学的Nicholas E. Geacintov教授和他的同事Michael D. Ward将获得一台带有二维gadd（一般面积探测器衍射系统）探测器的网络x射线微衍射仪。该仪器将被配置为提供一个紧密准直的单色光束，光斑直径范围从10 - 1000微米，允许单晶和多晶化合物的结构表征，具有高度的空间分辨率。该仪器将支持一系列领域的研究，如外延结晶、多态性、生物矿物微晶体、肽基材料、共聚物、金属有机阵列、仿生学、生物活性陶瓷、有机导体、分子磁体和分子阵列。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邻近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、材料化学和生物化学。该仪器将成为教学和研究的一个组成部分。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Chemistry Research Instrumentation and Facilities Multiuser Program (CRIF:MU), Professor Nicholas E. Geacintov and colleague Michael D. Ward from New York University will acquire a cyber-enabled X-ray microdiffractometer with a 2-dimensional GADDS (General Area Detector Diffraction System) detector. This instrument will be configured to deliver a tightly collimated monochromatic beam with spot diameters ranging from 10 - 1000 micrometers to allow structural characterization of single-crystal and polycrystalline compounds with a high degree of spatial resolution. This instrument will support research in an array of areas such as epitaxial crystallization, polymorphism, biomineral microcrystals, peptoid-based materials, copolymers, metal-organic arrays, biomimetics, bioactive ceramics, organic conductors, molecular magnets, and molecular arrays.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 studies described here will impact a number of areas, including chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research.
