Structural (volume fractions of the gel phase and the intergel solution) and transport
(electrical conductivity, diffusion permeability, transport numbers of counterions and coions) …

Permeability of sulphuric acid through cation‐exchange membranes of different
inhomogeneity has been investigated. It has been found that the diffusion coefficient of the …

Diffusion coefficients of water as a solvent and ethanol as a tracer in sulphonated
polyethylene (SPE) were measured by the pulsed-gradient spin-echo NMR method …

Water exchange through erythrocyte membranes occurs rapidly in the order of milliseconds.
This relatively high rate of transport requires special methods for investigation among which …

Pulsed field gradient spin echo NMR is generally the method of choice for diffusion
measurements on liquid samples. With modern high field instruments, however, severe …

The self-diffusion coefficients of N (CH3) 4+ ions in a cation-exchange membrane, the
Nafion, have been measured at different time scales. The time range extends from the …

The rate of exchange of 13 C-labelled bicarbonate across the membranes of human
erythrocytes in suspension, at thermal and chemical equilibrium, was measured using 13 C …

Membrane technologies are widely demanded in a number of modern industries. Ion-
exchange membranes are one of the most widespread and demanded types of membranes …

A theoretical treatment of the electrical conductance and tracer permeability of lipid bilayer
membranes in the presence of macrocyclic ion carriers is given. The analysis is based on …
