An intriguing phenomenon of reversible flocculation of charge-stabilised colloids in liquid mixtures is described. Some recent results concerning the shape of the flocculation surface, especially near special critical points (e.g. a double critical point, DCP), are also discussed. The findings...

We demonstrate with the aid of visual investigations that multiply reentrant liquid–liquid transitions can be obtained in ethyl alcohol (E)–water (W) mixtures, by the addition of ions. Multiplicity of reentrance can be tuned by changing the concentration, size, or the structure forming...

The light scattering measurements that yield the osmotic susceptibility (χT) in a ternary liquid mixture of 3-methylpyridine+water+sodiumbromide are presented. The measurements have been performed in the one-phase region near the lower consolute points TL's of samples with different...

Measurements are reported of the intensity and the angular dissymmetry of light scattered from ‘quasi-binary’ and binary mixtures of ethane and heavier hydrocarbons, that have varying widths of the three-phase region (ΔT). The critical exponents γ and v are estimated by approaching the...
