小行星9512503 将获得一台电荷耦合器件（CCD）、高强度X射线衍射仪，并用于材料合成和生物技术研究。CCD检测器和相关软件允许接近单光子检测效率和512 x512像素的快速读出时间。该仪器的易用性和快速筛选时间将允许快速表征小至几微米的晶体和不稳定且在X射线束中易于劣化的分子晶体。生物分子相和基于液晶/膜的复合材料具有产生大范围散射强度的大晶胞结构，将在结构上使用该仪器。沸石，多孔介观结构材料，富勒烯型结构，不能以其他方式表征，因为它们的低散射截面，也将进行研究。该仪器提供的灵敏度的大幅提高，与可用的核磁共振（NMR）资源相结合，代表了研究复杂的部分有序聚合物材料的独特能力。 高灵敏度，快速数据收集，X射线衍射仪将使一个新的材料表征能力，将影响现有的跨学科计划的100多名学生和教师。它将促进与先进材料的设计，合成和加工有关的研究计划，复杂流体和生物系统中的非平衡转化研究，以及蛋白质结构-性质关系。 ***

9512503 Stucky A charge coupled device (CCD), high intensity X-ray diffractometer will be acquired and utilized for materials synthesis and biotechnology research. The CCD detector and associated software allow for nearly single photon detection efficiency and rapid readout time of 512x512 pixels. The ease of use and rapid screening time of this instrument will permit the quick characterization of crystals as small as a few micrometers and of molecular crystals that are unstable and tend to deteriorate in the X-ray beam. Biomolecular phases and liquid crystal/membrane based composites with large unit cell structures that produce a large range of scattered intensities will be structurally accessible with this instrument. Zeolites, porous mesostructured materials, and fullerine-type structures that cannot be otherwise characterized because of their low scattering cross section, will also be studied. The large improvement in sensitivity provided by this instrument, in combination with available nuclear magnetic resonance (NMR) resources, represents a unique capability for studying complicated partially ordered polymeric materials. %%% The high sensitivity, fast data collection, x-ray diffractometer will enable a new materials characterization capability that will impact an existing interdisciplinary program of over one hundred students and faculty. It will facilitate research programs concerned with the design, synthesis, and processing of advanced materials, studies of non- equilibrium transformations in complex fluids and biological systems, and protein structure-property relationships. ***
