Small-angle X-ray scattering was used to study semidilute polystyrene-cyclohexane solutions at temperatures from below the coexistence curve to above the O point. Deviations from O point concentration scaling were observed as the coexistence line was approached. A new scaling form is suggested which

## Abstract Densified polystyrene glasses, prepared by cooling from the liquid state under elevated pressure, were studied by smallβangle xβray scattering at ambient pressure. The density fluctuation, determined from the xβray data, showed a decrease with increasing pressure up to about 1.5 kbar, a
Small-angle X-ray scattering was used to probe the structure of actin in the presence of cryosolvents: 1,2-propanediol, glycerol, or a mixture of both solvents. In media devoid of polymerizing salts, a radius of gyration of 23 A is measured, as expected from the literature. In the presence of 1,2-pr
