Purchase of a Variable Temperature X-Ray Diffractometer

根据化学研究仪器和设施多用户计划（CRIF:MU）的奖励，来自纽约州立大学石溪分校（SBU）的Benjamin S. Hsiao教授及其同事Nancy S. Goroff和Peter G. Khalifah将获得一台具有可变温度控制的x射线衍射仪和一台配置用于增强钼辐射源的4圆kappa角计。该仪器将使来自九个不同研究小组的学生受益，他们将定期使用该衍射仪。将受益于该奖项的主要研究项目是在无机周期性固体、无机框架材料、锂离子电池和其他层状材料、有机金属酶模型、过渡金属配合物、晶体工程和拓扑化学聚合、分子电子学、共轭有机材料和电子材料物理等领域。此外，SBU至少有11个其他研究小组，其研究范围从合成有机化学到陆相岩浆形成，将从偶尔获得这些升级的能力中受益。x射线衍射仪可以精确测量分子的完整三维结构，包括键的距离和角度，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。

With this award from the Chemistry Research Instrumentation and Facilities Multiuser Program (CRIF:MU), Professor Benjamin S. Hsiao and colleagues Nancy S. Goroff and Peter G. Khalifah from SUNY Stony Brook (SBU) will acquire an X-ray diffractometer with variable temperature control and a 4-circle-kappa goniometer configured for an enhanced molybdenum radiation source. This instrument will benefit students from nine different research groups who will use the diffractometer on a regular basis. The main research projects that will benefit from this award are in the areas of inorganic periodic solids, inorganic framework materials, lithium-ion batteries and other layered materials, organometallic enzyme models, transition metal complexes, crystal engineering and topochemical polymerizations, molecular electronics, conjugated organic materials, and physics of electronic materials. In addition, at least 11 other groups at SBU, whose research ranges from synthetic organic chemistry to terrestrial magma formation, will benefit from occasional access to these upgraded capabilities.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 and biochemistry. This instrument will be an integral part of teaching as well as research.
