摘要
Recent experimental results from ultra-small -angle neutron and X-ray scattering (USANS and USAXS) studies of complex fluids, including colloidal dispersions, colloidal glasses, polymer blends, and biopolymer gels, are reviewed. We focus on data analysis and interpretation in the low q regime. New notable results include the apparent existence of large-scale structure in attractive colloidal glasses, the discovery of new morphological transitions in polymer blends via USANS, and the detection of micron-scale water channels in biopolymer gels.
