Electrostatic Potentials at Membrane-Solution Interfaces
TL;DR: The chapter describes hydrophobic adsorption of charged molecules to bilayer membranes, the electro static potential produced by molecular dipoles at membrane-solution interfaces, and the electrostatic boundary potentialproduced by charges located in the interior of the membrane, a few angstroms from the interface.

Two mechanisms of permeation of small neutral molecules and hydrated ions across phospholipid bilayers
TL;DR: The proposed method of calculation of the Gibbs free energy of ion or dipole membrane transfer and the liquid membrane permittivity can be effectively used not only in describing the biophysical properties of membranes, but also in extraction processes, pharmaceutical applications and liquid membrane separations.

Shape of the hydrophobic barrier of phospholipid bilayers (Evidence for water penetration in biological membranes)
TL;DR: The shape of the hydrophobic barrier of lipid bilayers, fatty acids andl-α-lecithins with doxyl is plotted as a polarity index operationally defined in terms of the ΔA of the lipid spin labels.

Ion transport across thin lipid membranes: a critical discussion of mechanisms in selected systems.
D.A. Haydon,Stephen B. Hladky +1 more
TL;DR: In this paper, a review of the role of 1-carriets in the transfer of ions across thin lipid bilayer membranes is presented, focusing on simpler systems, i.e., the lipid-soluble ions, the 1-1 carriets, a simple pore and a substance which prodeces interacting pores.

Permeability of lipid bilayers to water and ionic solutes.
David W. Deamer,John Bramhall +1 more
TL;DR: It is concluded that at least two varieties of transient defects are required to explain permeation of water and ionic solutes, including proton-hydroxide flux.

Nonlinear Electrical Effects in Lipid Bilayer Membranes: I. Ion Injection
D. Walz,E. Bamberg,P. Läuger +2 more
TL;DR: The result shows that the ion injection effect gives a contribution to the current-voltage characteristic only at low ionic strength (< 10 (3)M) of the aqueous solution.

C. Huang,T.E. Thompson +1 more
TL;DR: The 61 A thickness of these membranes is compatible with the view that the structure is a bimolecular leaflet similar to the postulated structural form of the lipid component of biological membranes.
