Neutronography is a unique tool that allows extracting structural information due to the detection of light chemical elements in materials, high penetrating power, and isotopic sensitivity of neutron radiation. To date, one of its most popular areas is small-angle neutron scattering (SANS). The talk will be devoted to the SANS method as a tool for studying various structures on a scale from nanometers to micrometers. The physical principles underlying the method will be briefly outlined. Particular attention will be paid to practical applications in the frame of complex structural studies of nanoparticulate systems. Approaches to data analysis will be accompanied by an experimental examples. The advantages and disadvantages of using neutrons comparing to X-rays, including synchrotron radiation, will be noted.
