Comparison of the van der Waals and undulation interactions between uncharged lipid bilayers
Article Abstract:
A numerical analysis of the long-range interaction energies between neutral multilamellar lecithin systems has been conducted. The analysis was made in order to verify if the long-range swelling behavior that occurs between the two undulating lipid bilayer are really due to undulation repulsion. The results, which include a long-range van der Waals interaction that continues to be more than 1 order of magnitude greater than the measured undulation repulsion, suggest a different cause for the swelling.

Surface equation of state for insoluble surfactant monolayers at the air/water interface
Article Abstract:
A theoretical model has been developed to analyze the liquid-expanded-liquid-condensed phase transition. The model treats the monolayer as a two-dimensional mixture composed of liquid-condensed domains, disordered molecules in the liquid-expanded state, and free sites. The new equation minimizes the Helmholtz free energy of the monolayer to obtain the equilibrium radius and the equilibrium area fraction of the domains as a function of the average molecular surface area.

Tunable delocalization of unpaired electrons of nitroxide radicals for sickle-cell drug improvements
Article Abstract:
Hydroxyurea, a drug approved to treat sickle cell diseases, benefits the patients by increasing the level of fetal hemoglobin via nitroxide radical pathway. An unpaired-electron--delocalization approach is reported to tune the stability of nitroxide radicals.
