TL;DR: In this article, the principles of the Lifshitz theory of van der Waals interaction are used to formulate and compute energies in multilayer systems and the full analysis including relativistic, temperature, and many-body effects reveals a nonadditive long-range interaction that is not predicted by earlier theories.
Abstract: The principles of the Lifshitz theory of van der Waals interaction are used to formulate and compute energies in multilayer systems. The full analysis including relativistic, temperature, and many‐body effects reveals a nonadditive long‐range interaction that is not predicted by earlier theories.

TL;DR: A general method for measuring forces between planar phospho-lipid membranes is devised, and results for the specific case of egg lecithin (phosphatidyl choline) bilayers in water are reported.
Abstract: CELL fusion1 and vesicle-membrane2 or vesicle-synapse3 fusion are currently thought to involve distance-dependent interactions between membranes. We have devised a general method for measuring such forces between planar phospho-lipid membranes, and report here results for the specific case of egg lecithin (phosphatidyl choline) bilayers in water.

TL;DR: In this article, the functional dependences of steric interaction of undulating membranes are derived in a new way from simple physical arguments, and it is shown that the net energy of cohesion can be extremely small (≲10−5 erg cm−2).
Abstract: The theory of undulations of fluid membranes is reviewed and in some parts extended. The functional dependences of the steric interaction of undulating membranes are derived in a new way from simple physical arguments. Discussing the competition between steric repulsion and van der Waals attraction, one finds that membranes which usually separate (e.g. giant egg lecithin vesicles) should cohere if under lateral tension. The contours of two cohering vesicles observed when egg lecithin was swelling are analysed to show that the net energy of cohesion can be extremely small (≲10−5 erg cm−2).

TL;DR: The original DLVO theory does not account for specific ion effects embraced by the term Hofmeister series nor did it pretend to as mentioned in this paper, and no theories have considered the effects of dissolved gas which are extremely important.

TL;DR: The van der Waals forces refer to the attractive forces acting between any two neutral atoms or molecules that are separated by distance large compared to their own dimensions, which decrease with distance according to a power law as mentioned in this paper.
Abstract: Publisher Summary The van der Waals forces refer to the attractive forces acting between any two neutral atoms or molecules that are separated by distance large compared to their own dimensions. These forces are of a long-range nature, which decrease with distance according to a power law. The basic idea of the theory is that the interaction between the bodies is considered to take place through a fluctuating electromagnetic field. This field is always present in the interior of a material medium and it also extends beyond its boundaries because of the thermodynamic fluctuations. Any change in the electrical proper ties of the medium in a certain region will, by Maxwell's equations, lead to a change in the fluctuation field that extends beyond that region. Therefore, the part of the free energy that is related to electromagnetic fluctuations is not determined by the properties of the substance solely at the point considered.

TL;DR: The interpretation of the electron microscope observations of the structure of lipoprotein membranes is discussed, and some possible biological implications are suggested.
Abstract: Some simple lipid-water systems have been studied by x-ray scattering techniques, as a function of lipid concentration and temperature. Several liquid-crystalline phases have been found, and their structure has been determined: only one of these is lamellar. In all these phases the hydrocarbon part of the lipid molecules has a disordered, liquid-like structure. One biological phospholipid, a human brain extract, has been studied by the same technique, and two liquid-crystalline phases have been found: a lamellar phase, built up by an ordered sequence of lipid and water planar sheets, and a hexagonal phase, which is a hexagonal array of circular cylinders, each cylinder being a thin water channel covered by the hydrophilic groups of the lipid molecules, the hydrocarbon chains filling the gap between the cylinders. The interpretation of the electron microscope observations of the structure of lipoprotein membranes is discussed, and some possible biological implications are suggested.
