Small Angle Neutron Scattering (SANS) is a technique that allows characterizing structures or objects on the nanometer scale, typically in the range between 1 nm and 150 nm. The information one can extract from SANS is primarily the average size, size distribution and spatial correlation

The use of small-angle X-ray and neutron scattering - SAXS/USAXS & SANS/USANS – can, for many problems, significantly advance the quality of materials characterization and therefore user research. Sometimes the combined use of SAXS and SANS may be the only way to fully unravel complex microstructures (see model example at the end of this page).

3 Small Angle Neutron Scattering The discussion above focussed on atomic properties, but there are many problems where the length scales in question are much larger than atomic dimensions and it is easier to think in terms of material properties. In order to do this we de ne a quantity called the scattering length density ˆ(r) = b i (r r i) (16) or ˆ= P n i b

In this work, data collected from neutron scattering experiments will be evaluated. The data was gained using small-angle neutron scattering (SANS) at the instrument Sans2D at the ISIS-facility in England. A whole wavelength spectrum was used, the wavelengths of the neutrons are measured by their time of flight from the source to the detector. Small angle X-ray and neutron scattering theory; Sample requirements for a successful small angle scattering experiment; Data analysis, model building and interpretation; Isotope labelling strategies for small angle neutron scattering; Analysing small angle scattering in conjunction with data obtained from other techniques (NMR, AUC, EM, SEC-MALLS) Small-angle scattering of X rays and neutrons is a widely used diffraction method for studying the structure of matter.

An incoming beam is scattered at the sample Ultra-small-angle neutron scattering provides a new way to solve a broad range of scientific problems such as: Structure of soft matter systems including polymer solutions and melts, colloidal suspension and micellar solutions Structure of precipitate strengthened alloys Phase transitions and critical phenomena Small angle neutron scattering (SANS) is a powerful technique for investigating association states and conformational changes of biological macromolecules in solution. SANS is of particular interest for the study of the multi-component systems, as membrane protein complexes, for which in vitro characterisation and structure determination are often difficult. Small angle scattering of X-rays (SAXS) and neutrons (SANS) is an established method for the structural characterisation of biological objects in a broad size-range from individual macromolecules (proteins, nucleic acids, lipids) to large macromolecular complexes. Recent improvements in beam-line accessibility and technology have led to small-angle neutron scattering (SANS) becoming more frequently applied to materials problems. SANS has been used to study the assembly, dispersion, alignment and mixing of nanoscale condensed matter, as well as to characterise the internal structure of organic thin films, porous structures and inclusions within steel.

Small-angle neutron scattering (SANS) and small-angle x-ray scattering (SAXS) are excellent tools for the characterization of those inhomogeneities whose dimensions are in the nanometer range, such as precipitates, voids, and gas bubbles (see Metallurgy: Small-angle Scattering).
