Webb12 apr. 2024 · Small-angle neutron scattering (SANS) is an experimental technique that uses elastic neutron scattering at small scattering angles (<10 o) to investigate the structure over length scales of 1-100 nm. During a SANS experiment a beam of neutrons is directed at a sample, which can be an aquoues solution, a solid, a powder, or a crystal. WebbWe have studied the phase behavior, wetting transitions, and small angle neutron scattering (SANS) of water, n-alkane, and n-alkyl polyglycol ether (CiEj) systems in order to locate the transition between weakly structured mixtures and microemulsions, and to provide a measure for the transition.
