Rapid transport of macromolecules in polysaccharide systems by means of dissipative structures.
A gravitationally stable boundary between two polymer solutions in a ternary system can develop into an interphase of structured convectional flow. The transport over this interphase is by counter-current distribution and as a result high-molecular weight material moves by bulk-flow and much more rapidly than low-molecular weight material, which is transported essentially by ordinary diffusion.
