Going Ultra: How We Can Increase the Length Scales Studied in Small‐Angle Neutron Scattering

Abstract Small‐angle neutron scattering (SANS) has over the years proved to be a popular technique to investigate a variety of problems in materials science, since the length scales probed by this technique (1–100 nm) are ideal for many systems. However, there are a number of problems where the length scale of interest is larger. In order to study such systems it is possible to combine SANS with ultra‐small‐angle neutron scattering (USANS). This allows the study of structures from a few nanometers up to 50 µm. Here it is shown how the combination of SANS and USANS has allowed for a wider range of problems within materials science and polymer science to be solved.
