We study the interfacial properties of systems containing like-charged rods with charge fluctuations along their length. We show that it is possible to describe clusters of rods in terms of the sum of a bulk free energy and a surface free energy. It is not obvious that this is valid for...

Phase transitions of a multilamellar system Lα composed of water, lipids and PEG-lipids are investigated. Increasing the water fraction or the PEG-lipids concentration of such a system, the fluid multilamellar phase changes to a gel phase and then returns to a fluid phase. Since flat layers...

It is well known that the Poisson–Boltzmann (PB) equation yields the exact counterion density around charged objects in the weak coupling limit. In this paper, we generalize the PB approach to account for coupling of arbitrary strength by making use of Tsallis q-exponential distributions. Both...
