small-angle scattering

Small-angle scattering is a technique used to study the structure of materials at a microscopic level by shining a beam of particles or radiation (like X-rays or neutrons) at a sample. When these particles encounter features within the material, they scatter slightly, and by measuring this scattering at very small angles, scientists can infer information about the size, shape, and arrangement of tiny structures—such as pores, fibers, or particles. This method provides valuable insights into the internal architecture of complex materials without destroying them.
