Query: Microscopic modeling of contact formation between confined surfaces in
  solution   We derive a Kinetic Monte Carlo model for studying how contacts form between
confined surfaces in an ideal solution. The model incorporates repulsive and
attractive surface-surface forces between a periodic (2+1)-dimensional
solid-on-solid (SOS) crystal surface and a confining flat surface. The
repulsive interaction is derived from the theory of electric double-layers, and
the attractive interactions are Van der Waals interactions between particles on
the SOS surface and the confining surface. The confinement is induced by a
constant external pressure normal to the surfaces which is in mechanical
equilibrium with the surface-surface forces. The system is in thermal
equilibrium, and particles can deposit to and dissolve from the SOS surface.
The size of stable contacts formed between the surfaces in chemical equilibrium
show a non-trivial dependency on the external pressure which is
phenomenologically similar to the dependency of oscillatory hydration forces on
the surface-surface separation. As contacts form we find classical phenomena
such as Ostwald ripening, coalescence, and primary and secondary nucleation
stages. We find contacts shaped as islands, bands or pits, depending solely on
the contact size relative to the system size. We also find the model to behave
well out of chemical equilibrium. The model is relevant for understanding
processes where the force of crystallization and pressure solution are key
mechanisms.
