IMR: Acquisition of a Small-Angle X-Ray Scattering Camera for Research and Education

一种新的小角度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表征的迫切需求。该仪器将作为一个多用户设施，提供给所有的教师和学生在COE和其他单位特拉华大学。基于其功能、分辨率、易用性和数据分析软件的质量，我们选择了安东帕（SAXSess）的高通量SAXS系统作为COE最合适的仪器。它使用来自传统x射线管的线形光束，通过多层光学和块准直器进行聚焦，产生强烈的主光束。该信号由二维成像板检测，其q范围非常适合我们要研究的样品。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度的散射角范围。小角散射是表征纳米结构材料和复杂流体的关键。随着当前研究范式中对纳米技术的重视，当然在UD，这个新的SAXS将填补COE中材料表征的巨大空白。S的研究能力，并为8个直接用户提供研究效益。在COE和物理和天文学中，多达8名额外的研究人员表示需要SAXS功能。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)研究表面活性剂胶体聚集体的结构和稳定性。一种新的小角度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表征的迫切需求。该仪器将作为一个多用户设施，提供给所有的教师和学生在COE和其他单位特拉华大学。小角散射是表征纳米结构材料和复杂流体的关键。随着当前研究范式中对纳米技术的重视，当然在UD，这个新的SAXS将填补COE中材料表征的巨大空白。S的研究能力，并为8个直接用户提供研究效益。在COE和物理和天文学中，多达8名额外的研究人员表示需要SAXS功能。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增强的自组装纳米复合材料；(2)研究有机硅纳米粒子在水溶液中的自组装；(3)研究表面活性剂胶体聚集体的结构和稳定性

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.
