Many research groups of the Department of Chemistry and Pharmacy at the University of Münster, including the Gröschel group, deal with the synthesis and characterization of functional nanomaterials built from synthetic, biological and inorganic components. The Gröschel group thereby focuses on block copolymer nanostructures in bulk, thin films and solutions, as well as polymer-based mesoporous materials, polymer / metal hybrids, nanostructured colloids, and nanoparticle crystals. The acquisition of a small-angle X-ray scattering (SAXS) system is intended to close a gap in the methods used by the Gröschel group for structure characterization. Analysis of the superstructures involves measurements of the intermediate and final structure on different length scales in the range of 1-300 nm, which requires SAXS and wide-angle (WAXS) detection with ultra-high resolution. The method provides information on long-range order of the nanostructures, pair distance distribution functions, averaged structural features over large sample volumes, and allows following morphological transitions (e.g. through annealing, light stimulation or other stimuli). Information about structural transitoins is of particular interest for a better understanding of the formation mechanism and structure-property relationships. The method of SAXS is currently not available in the Department of Chemistry and Pharmacy or at the University of Münster and its affiliated institutes.

明斯特大学化学与药学系的许多研究小组（包括 Gröschel 小组）致力于由合成、生物和无机成分构建的功能性纳米材料的合成和表征，因此 Gröschel 小组专注于块状共聚物纳米结构。 、薄膜和溶液，以及基于聚合物的介孔材料、聚合物/金属杂化物、纳米结构胶体和纳米颗粒晶体。小角 X 射线散射 (SAXS) 系统旨在弥补 Gröschel 小组用于结构表征的方法中的差距。 上部结构分析涉及在 1 范围内的不同长度尺度上测量中间和最终结构。 -300 nm，需要超高分辨率的 SAXS 和广角 (WAXS) 检测。该方法提供有关纳米结构的长程有序、对距离分布函数、大样本量的平均结构特征的信息。并允许进行以下形态转变（例如通过退火、光刺激或其他刺激）。有关结构转变的信息对于更好地理解形成机制和结构-性质关系特别重要。该部门目前尚不提供 SAXS 方法。化学与药学系或明斯特大学及其附属机构。
