The application of ultra-small-angle neutron scattering in material research

Material researches by use of Ultra-small-angle neutron scattering (USANS) have to be introduced, including experiments have to be carried in polymer science, fractal geometry of rocks, multiplex, complex fluids, hydrogels, artificial lattices, metal materials and high energy materials etc. It is show that, in addition to traditional small-angle-neutron scattering (SANS) techniques and so on, more comprehensive information of inner structure of materials can be acquired when combined with USANS, and this offer important help to resolve some material science problems.
