A new Small-Angle X-ray Scattering (SAXS) System will fulfill immediate needs in the characterization of polymeric, catalytic, biological, electroactive, nanocomposite and other classes of materials and complex fluids. The instrument will be used as a multi-user facility available to all faculty and students in the COE and other units at UD. We have selected the high-flux SAXS system from Anton Paar (SAXSess) as the most suitable instrument for the COE on the basis of its capabilities, resolution, ease of use and the quality of the software for data analysis. It uses the line-shaped beam from a conventional X-ray tube that is focused using multilayer optics and a block collimator to produce an intense primary beam. The signal is detected by a 2D imaging plate and the q range is very suitable for the samples that we propose to investigate. It has a built-in pinhole option that can be used to investigate oriented anisotropic samples and we plan to include the wide-angle extension that allows for the simultaneous measurement of the angular range from 0 degrees to 45 degrees of scattering angle. Small angle scattering is essential for the characterization of nanostructured materials and complex fluids. With the large emphasis on nanotechnology in the current research paradigm, and certainly here at UD, this new SAXS will fill a large materials characterization gap in the COE.s research capabilities and provide research benefit to 8 immediate users. Up to 8 additional investigators both in the COE and in Physics and Astronomy have expressed the need for SAXS capabilities. The major users of the instrument will utilize it for the characterization of (1) self-assembled nanocomposite materials using biopolymer matrices and clay platelet or peptide fibrillar nanoscopic reinforcement; (2) to study the self-assembly of organic-silica nanoparticles in aqueous solutions; and (3) to investigate the structure and stability of colloidal surfactant aggregates. %%%A new Small-Angle X-ray Scattering (SAXS) System will fulfill immediate needs in the characterization of polymeric, catalytic, biological, electroactive, nanocomposite and other classes of materials and complex fluids.

一种新的小角X射线散射（SAXS）系统将满足聚合物，催化，生物，电活性，纳米复合材料和其他类型的材料和复杂流体的表征的迫切需要。该仪器将被用作一个多用户设施提供给所有教师和学生在COE和其他单位在UD。我们选择安东帕尔的高通量SAXS系统（SAXSess）作为COE最合适的仪器，这是基于其功能、分辨率、易用性和数据分析软件的质量。它使用来自传统X射线管的线形光束，使用多层光学器件和块准直器聚焦以产生强烈的初级光束。 信号由2D成像板检测，并且q范围非常适合我们建议调查的样品。它有一个内置的针孔选项，可用于研究定向各向异性样品，我们计划包括广角扩展，允许同时测量从0度到45度散射角的角度范围。 小角散射对于纳米结构材料和复杂流体的表征至关重要。 由于当前的研究范式非常重视纳米技术，尤其是在UD，这种新的SAXS将填补COE研究能力中的巨大材料表征空白，并为8个直接用户提供研究益处。 另有多达8名COE和物理学与天文学研究人员表示需要SAXS能力。该仪器的主要用户将利用它来表征（1）使用生物聚合物基质和粘土血小板或肽纤维纳米级增强的自组装纳米复合材料;（2）研究有机二氧化硅纳米颗粒在水溶液中的自组装;（3）研究胶体表面活性剂聚集体的结构和稳定性。 一个新的小角X射线散射（SAXS）系统将满足聚合物，催化，生物，电活性，纳米复合材料和其他类别的材料和复杂流体的表征的迫切需要。该仪器将被用作一个多用户设施提供给所有教师和学生在COE和其他单位在UD。 小角散射对于纳米结构材料和复杂流体的表征至关重要。 由于当前的研究范式非常重视纳米技术，尤其是在UD，这种新的SAXS将填补COE研究能力中的巨大材料表征空白，并为8个直接用户提供研究益处。 另有多达8名COE和物理学与天文学研究人员表示需要SAXS能力。该仪器的主要用户将利用它来表征（1）使用生物聚合物基质和粘土血小板或肽纤维纳米级增强的自组装纳米复合材料;（2）研究有机二氧化硅纳米颗粒在水溶液中的自组装;（3）研究胶体表面活性剂聚集体的结构和稳定性。
