Abstract:
We calculate the effective interaction between two solute particles in a solvent of Lennard-Jones (LJ) particles in two dimensions where the solvent is in the stable liquid phase near the liquid-gas phase coexistence and the solute-solvent interaction is repulsive. Our grand canonical Monte Carlo (GCMC) simulations show that the effective interaction between two solute particles is attractive for separations between the solute particles up to a range of a few nanometres, beyond which the interaction exhibits a marked repulsion. Such an effective interaction stabilizes clusters of nanometre (nm) sizes.

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
