Title: Critical behaviour of complex fluids and supramolecular length scale

Abstract: A few aspects of complex fluids (electrolyte solutions, polymer solutions, amphiphilic systems, etc.) from the perspective of critical behaviour normally observed in non-interacting, neutral fluids have been presented. A recurring theme in complex fluids is the structuring of these systems and the associated supramolecular (mesoscopic) length scale. The authors adduce evidence to support the claim that, intriguing and poorly understood features emerge in electrolyte solutions and the dilute suspensions of charge-stabilized colloids in liquid solutions. These results are based on investigations near to and away from liquid-liquid critical point using laser light scattering, turbidity, small-angle X-ray scattering (SAXS), visual observations and the excess molar volume measurements.
