Special Issue Information

Dear Colleagues,

Membrane transport (mass, charge, energy, etc.) through artificial and biological membranes, generated by various thermodynamic forces, is one of the basic processes occurring in thermodynamic systems. It is even believed that the biological membrane, which reacts to external factors, acts as a cell management center.

A convenient way to study membrane transport is through the construction of thermodynamic models and, if possible, their experimental verification or falsification. In recent years, numerous papers have been devoted to basic and utilitarian research (engineering, biomedical, etc.) of membrane transport through various types of artificial membranes and their systems.

We invite scientists to submit original research and/or review papers focused on this important area of membrane science, the field of thermodynamic modeling of transport in membrane systems, emphasizing recent findings and developments, future challenges, and/or new opportunities in which to develop guidelines for future research directions.

This Special Issue will accept unpublished original papers and comprehensive reviews focused on (but not restricted to) the following research areas:

theoretical analyses of membrane transport phenomena
experimental results on membrane permeation and selectivity
membrane formation and structure and their relation to transport properties
nonequilibrium thermodynamics
network thermodynamics
membrane formation
thermodynamic properties of membrane
passive and active membrane transport processes
concentration polarization conditions
membrane dressing
controlled release of substances
membrane potentials
energy, exergy, and entropy generation
composite membranes

Hence, this Special Issue will serve as the ideal venue for the publication of new developments in the membrane field.

Abstract

The study of drugs diffusion through different biological membranes constitutes an essential step in the development of new pharmaceuticals. In this study, the method based on the monolayer cell culture of CHO-K1 cells has been developed in order to emulate the epithelial cells barrier in permeability studies by laser interferometry. Laser interferometry was employed for the experimental analysis of nickel(II) and cobalt(II) complexes with 1-allylimidazole or their chlorides’ diffusion through eukaryotic cell monolayers. The amount (mol) of nickel(II) and cobalt(II) chlorides transported through the monolayer was greater than that of metals complexed with 1-allylimidazole by 4.34-fold and 1.45-fold, respectively, after 60 min. Thus, laser interferometry can be used for the quantitative analysis of the transport of compounds through eukaryotic cell monolayers, and the resulting parameters can be used to formulate a mathematical description of this process.

The results of experimental studies of volume osmotic fluxes (

J_{v k}^{r}

) and fluxes of dissolved substances (

J_{k}^{r}

) in a system containing a synthetic Nephrophan^® membrane (Orwo VEB Filmfabrik, Wolfen, Germany) set in a horizontal plane are presented. The membrane separated water and aqueous HCl or ammonia solutions or aqueous ammonia and HCl solutions. It was found that for the homogeneity conditions of the solutions

J_{v k}

and

J_{k}

depend only on the concentration and composition of the solutions. For concentration polarization conditions (where concentration boundary layers are created on both sides),

J_{v k}^{r}

and

J_{k}^{r}

depend on both the concentration and composition of the solutions and the configuration of the membrane system. The obtained results of the

J_{v k}

and

J_{k}

flux studies were used to assess the global production of entropy for the conditions of homogeneity of solutions (

Φ_{S k}

), while

J_{v k}^{r}

and

J_{k}^{r}

—to assess the global production of entropy for concentration polarization conditions

(Φ_{S k}^{r}

). In addition, the diffusion-convective effects and the convection effect in the global source of entropy were calculated. The concentration polarization coefficient

ζ_{i}^{r}

was related to modified concentration Rayleigh number, e.g., the parameter controlling the transition from non-convective (diffusive) to convective state. This number acts as a switch between two states of the concentration field: convective (with a higher entropy source value) and non-convective (with a lower entropy source value). The operation of this switch indicates the regulatory role of earthly gravity in relation to membrane transport. Full article

The paper presents the

R^{r}

matrix form of Kedem–Katchalsky–Peusner equations for membrane transport of the non-homogeneous ternary non-electrolyte solutions. Peusner’s coefficients

R_{i j}^{r}

and det [

R^{r}

] (i, j ∈ {1, 2, 3}, r = A, B) occurring in these equations, were calculated for Nephrophan biomembrane, glucose in aqueous ethanol solutions and two different settings of the solutions relative to the horizontally oriented membrane for concentration polarization conditions or homogeneity of solutions. Kedem–Katchalsky coefficients, measured for homogeneous and non-homogeneous solutions, were used for the calculations. The calculated Peusner’s coefficients for homogeneous solutions depend linearly, and for non-homogeneous solutions non-linearly on the concentrations of solutes. The concentration dependences of the coefficients

R_{i j}^{r}

and det [

R^{r}

] indicate a characteristic glucose concentration of 9.24 mol/m³ (at a fixed ethanol concentration) in which the obtained curves for Configurations A and B intersect. At this point, the density of solutions in the upper and lower membrane chamber are the same. Peusner’s coefficients were used to assess the effect of concentration polarization and free convection on membrane transport (the ξ_ij coefficient), determine the degree of coupling (the

r_{i j}^{r}

coefficient) and coupling parameter (the

Q_{R}^{r}

coefficient) and energy conversion efficiency (the

{(e_{i j}^{r})}_{r}

coefficient). Full article
