2020年3月26日 · SAXS-CT is an emerging powerful imaging technique which bridges the gap between information retrieved from high-resolution local techniques and information from low-resolution, large field-of-view imaging, to determine the nanostructure characteristics of well-ordered tissues, e.g., mineralized collagen in bone. However, in the case of soft ...

2015年11月18日 · Small-angle X-ray scattering (SAXS) can, in principle, probe structural ordering across a wide range of length scales, from nanoscale to the macroscopic.

2021年5月19日 · Here, we exploit myelin’s nanostructural periodicity, and use small-angle X-ray scattering tensor tomography (SAXS-TT) to simultaneously quantify myelin levels, nanostructural integrity and axon...

小角 X 射线散射显微断层扫描 （SAXS-CT） 是一种前所未有的新方法，为揭示聚合物微观结构显示出强大的前景。 本研究已用于分析由具有各种参数的振荡剪切注射成型 （OSIM） 生产的聚己二酸丁二醇酯-共对苯二甲酸酯 （PBAT） 的梯度纳米结构。 使用这种方法的显着好处是，几毫米的样本几乎可以分成数千个体素，同时每个体素中的纳米结构信息都是无损提取的。 对于特定 OSIM 加工生产的每个样品，重建近 10,000 个二维散射图案，并根据巨大的散射数据一一绘制结构 …
