Ultra-small-angle scattering is a method for studying the size and shape of objects of size 10 µm and below by diffraction. If done with neutrons rather than X-rays, it becomes ultra-small-angle neutron scattering (or: USANS), and all the normal advantages of neutrons come into play: contrast different to that of X-rays, ability to vary contrast using deuteration, sensitivity to magnetism, and penetration into macroscopic samples.
Therefore, the USANS is useful for studies of pores and cracks in rocks, cement or engineering materials, very large biological or polymer molecules or macromolecular assemblies, and mesoscopic magnetic particles.
The range of interest includes bacteria, blood, cements, clays, clusters in metals, coals, colloids, complex fluids, emulsions, foams, food, gels, granular materials, hydrogels, membranes, micellar systems, minerals and mineral processing, nanocomposites, nanotechnology, phase transitions, polymer blends, polymers, porous materials, powders, precipitates, proteins, rocks, thin metallic or organic films, viruses, etc.
