The forces between two molecularly smooth mica surfaces were measured over a range of concentrations in aqueous Li -+, Na+, Kf and Cs\* chloride solutions. Deviations from DLVO forces in the form of additional short-range repulsive "hydration" forces were observed only above some critical bulk conce

โฆ Synopsis
Density functional theories of solvation forces in charged fluids are extended to treat electrolytes consisting of finitesized ions and neutral solvent particles. The resulting forces display pronounced oscillations whose magnitude is a strong function of the bulk density of the neutral species.

The behavior of self-assembled monolayers of thiohexadecanoic acid adsorbed onto gold interacting in asymmetric 2:1 electrolytes has been studied with direct force measurements. The effects of two divalent cations (Mg(2+) and Ca(2+)) were studied at concentrations ranging from 1 ยตM to 10 mM. As comp
We have investigated the forces between two surfaces, immersed in a dilute electrolyte solution, interacting specifically with the ions that are in their immediate vicinity. It is found that at large separations the free energy decays exponentially (the decay length being approximately half the Deby
