Electrically modulated membrane permeability

TL;DR: In this article, the swelling of crosslinked poly(N,N-alkyl substituted acrylamides) in water was studied in relation to changes in external temperature, and the significant swelling changes of the polymer in water in response to temperature can be attributed to the delicate hydrophilic/hydrophobic balance of polymer chain, and was affected by the size, configuration and mobility of the alkyl side chains on the substituted acylamides.

TL;DR: In this article, a crosslinked poly(N-isopropylacrylamide?co-butylmethacrylate 95:5mol%) membrane is used and three solutes of distinct molecular size: two dextrans with molecular weights of 150,000 and 4,400 g/mol respectively and uranine with a molecular weight of 376 g/m.

TL;DR: In this paper, a macroscopic continuum model is presented to predict the kinetics of swelling in polyelectrolyte gel membranes induced by augmentation of electrostatic swelling forces arising from membrane fixed charge groups.

TL;DR: In this article, the current status of our knowledge of electromechanical effects that take place in smart polymer gels is reviewed, and the mechanism of polyelectrolyte gel behavior in electric fields is investigated experimentally and then theoretically.

TL;DR: An equation for the flux of electrolyte through a water-swollen cation-exchange resin membrane separating two solutions of the same electrolyte at different concentrations is derived on the basis of several assumptions regarding the physical nature of a swollen resinous exchanger.

TL;DR: The basic hydrodynamic equations governing transport in submicron pores are reexamined and extensions of the analysis are shown to depend on numerical solutions of the related hydrod dynamic problem, that of asymmetrical particle motion in a bounded fluid.

TL;DR: This review has dealt primarily with the electromechanical and transport properties of the extracellular matrix, which generally contains ionized charged groups under physiological conditions and may suggest that electrical, mechanical and chemical signals are somehow interpreted by the cells along common pathways.
