Abstract:
We report a molecular simulation study of aqueous solutions at montmorillonite clay surfaces. Unlike most previous studies, ours does not focus on the interlayer nanopores, but looks at both kinds of external surfaces of clay particles: basal surfaces along the clay layers, and lateral surfaces through which interlayer and larger interparticle pores are linked. We present results on structural, dynamic and thermodynamic properties and phenomena, including hydration complexes of ions, H bonding networks, modification of the water dynamics with respect to the bulk, and the role of water in the cation exchange between interlayer and interparticle pores.

Aqueous Solutions and Heats of Hydration
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...

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,...
