Facilitated diffusion normally involves mobile carriers, reactive groups which react with
specific solutes and diffuse with them across a liquid membrane. Facilitated diffusion can …

A generalized microscopic mechanism for the facilitated transport of a neutral solute through
a fixed site carrier membrane is given. A series mass transfer resistance model is used to …

The separation of molecules by membranes is not only a very important event in biological
systems, it has also important large-scale industrial applications, and therefore, it is of a …

The commonly accepted mechanism for the transport of a penetrant in nonporous polymer
membranes is solution-diffusion (Crank and Park 1968). The penetrant species dissolves in …

A theory is presented which describes the facilitated transport of neutral molecules, such as
O 2, across fixed site carrier membranes. A main feature of this theory is a derivation of the …

Carrier‐mediated transport in membranes as a globally nonreactive process is distinguished
from film theory with chemical reaction and other facilitated diffusion phenomena. With the …

Activated diffusions in condensed phases may be classified into two types: specific and non-
specific. A specific activated diffusion depends on a special affinity of the diffusing particle for …

The literature pertaining to facilitated transport and liquid membrane separations is reviewed
and summarized, especially work reported since 1977. Liquid membranes of all geometries …

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

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 …
