This work presents important new evidence that the crosslinked structure of swollen
polymers acts as a molecular screen for diffusion of large solutes. Diffusion experiments of …

A new theoretical model was developed for the description of spherical and quasispherical
solute diffusion through highly swollen polymeric networks and membranes. This model …

A theoretical model was developed to describe solute transport through moderately swollen
networks. The model is an extension of the previous analysis of Peppas and Reinhart …

The question of viscous flow versus molecular diffusion mechanisms for pressure‐induced
liquid transport through membranes is critically examined for the specific case of …

The present book contains a comparison of existing theoretical models developed in order
to describe membrane separation processes. In general, the permeation equations resulting …

The theory of diffusional release of a solute from a polymeric matrix where the initial loading
of solute is less than or greater than the solubility limit has been reviewed and extended …

A scaling law was developed for the diffusion coefficient of spheroidal and ellipsoidal
solutes in nonporous, equilibrium‐swollen hydrogels. The law relates the solute diffusion …

The conventional equations describing mass transport through membranes predict
proportionality between flux and driving force. Experimental results inconsistent with this …

The diffusional transport of aqueous solutes through water swollen polymer membranes is
examined by the concept of the free volume of the water‐polymer systems, Vf, 13. The …

A theoretical and experimental investigation has been made of steady-state diffusion in a
membrane in which flow occurs into and out of central discs at top and bottom surfaces …
