Small Angle X-ray Scattering (SAXS)

自组装结构在合成和天然材料的背景下都具有重大意义，因为它们导致具有定义的纳米结构的功能系统。最近的努力是针对编程的非平衡条件下的自组装的时间域，以创建类似生命（生物启发）的材料。在这种情况下，最基本的任务是致力于了解它们的结构-性质关系。小角X射线散射在将纳米结构与材料功能联系起来方面处于领先地位。RWTH亚琛大学的高分子材料和系统主席是生物化学和材料科学领域众多研究项目的所在地，但目前没有最先进的小角X射线散射用户设施来支持该团队。该提案的目的是获得一台小角X射线散射仪器，为亚琛地区的材料研究界提供直接访问现场小角X射线散射表征的广泛样品类型。拟议的系统将安装在技术和高分子化学研究所高分子材料和系统主席的实验室，并将提供给广泛的学术用户群。虽然补充现有的结构分析方法，SAXS填补了国家的最先进的材料表征设施的一个重要空白，并使研究和教育的一个不同群体的学生在化学，纳米材料和生物物理科学的增长。

Self-assembled structures are of substantial interest in the context of both synthetic and natural materials as they lead to functional systems with defined nanostructure. Recently the efforts are directed towards programming the time domain of self-assemblies under non-equilibrium conditions to create life-like (bioinspired) materials. The most fundamental task in this context is devoted to the understanding of their structure-property relationship. Small Angle X-ray Scattering is taking the lead in relating the nanostructures to the material functions. The Chair of Macromolecular Materials and Systems at RWTH Aachen University is home to numerous research projects in biochemistry and material science, but currently there are no state-of-the-art Small Angle X-ray Scattering user facilities to support the team. The objective of this proposal is to acquire a Small Angle X-ray Scattering instrument to provide the materials research community in the Aachen area with direct access to in-situ Small Angle X-ray Scattering characterization for a broad range of sample types. The proposed system will be installed in the laboratories of the Chair of Macromolecular Materials and Systems at the Institute for Technical and Macromolecular Chemistry and will be available to a broad academic user base. While complementary to the existing structural analysis methods, SAXS fills an important gap in the state-of-the-art materials characterization facilities and enabling the growth of research and education of a diverse group of students in chemistry, nanomaterials, and biophysical sciences.
