Fluctuations in Disordered systems Examined by Small-Angle Scattering

Abstract

Small-angle scattering is a very powerful method to investigate the structure of disorderd systems from mesoscopic viewpoint. In the present chapter, it is introduced how the inhomogeneity of molecular distribution in liquids or supercritical fluids (density fluctuation) and mixing state in solutions (mixing state) are obtained from the small-angle scattering technique.
