MRI: Acquisition of an X-Ray scattering system for polymer and nanomaterials research and education

纽约城市大学斯塔滕岛学院(CUNY CSI)的化学系将从主要研究仪器(MRI)计划中获得这一奖项。该奖项将资助具有广角能力的小角X射线散射系统(WAXS)，该系统将推进了解聚合物、液晶、表面活性剂、纳米晶体、生物材料和纳米结构材料的分级结构-性质关系的研究工作。它将指导合成高纯度、无孔的碳化硅材料和钛酸锶钡纳米晶体；探索C60/聚合物和阳离子多糖/阴离子表面活性剂络合物的自组装；辅助盘状液晶的研究；研究半导体液晶。小角X射线散射(SAXS)技术，有时与广角X射线散射(WAXS)相结合，已经成为表征软材料纳米结构的主要工具。这些技术可用于固体和液体，也可用于薄膜和定向样品，如聚合物纤维。该仪器将促进研究型学生在现代衍射技术方面的培训。它将用于本科生研究性实验教学。纽约市地区的其他城市大学校园和学术机构将可以使用这些仪器。

The Chemistry Department at the City University of New York, College of Staten Island (CUNY CSI) will acquire x-ray scattering instrumentation with this award from the Major Research Instrumentation (MRI) program. The award will fund a small-angle X-ray scattering system with wide-angle capabilities (WAXS) that will advance research work on understanding hierarchical structure-property relationship of polymers, liquid crystals, surfactants, nanocrystals, biomaterials, and nanostructured materials. It will guide the synthesis of high-purity, nonporous SiC materials and barium strontium titanate nano crystals; probe the self-assembly of C60/polymer and cationic polysaccharide/anionic surfactant complexes; aid in the study of discotic liquid crystals; investigate semiconducting liquid crystals. The small angle X-ray scattering (SAXS) technique, sometimes combined with wide-angle X-ray scattering (WAXS), has become a major tool for the characterization of nanostructures of soft materials. These techniques are available for solids and liquids, and have been also implemented for thin films and oriented samples, such as polymer fibers. The instrumentation will advance the training of research students in modern diffraction techniques. It will be used in undergraduate research laboratory instruction. Other CUNY campuses and academic institutions in the New York City area will have access to the instrumentation.
