Abstract:
Grand canonical Monte Carlo simulations are employed to investigate the structure of water adsorbed on kaolinite surfaces with trenchlike defects. The results obtained for two water models (SPC/E and TIP5P-E) at 235 K are essentially the same. Calculation of water density profiles in all three dimensions shows that a dense ordered state is present in our trench systems. The narrowest trenches have the highest water density and display clearly layered structures along the width and depth of a trench. The water within a trench shows distinct proton order and is strongly ferroelectric. These ordered structures might be important in the initial stages of nucleation and growth of ice on kaolinite surfaces.

Molecular and Ionic Solids
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
Electrostatic Boundary Conditions in Dielectrics
Consider a case where both the mediums across a boundary are two different dielectric materials. Recall that the electric field and electric displacement are proportional and related through the material's permittivity.
