Fig. (7) Top: Snapshots of the ethanol-water mixture in the presence of TiO2 (left) and Pt (right) surfaces. Middle: Z-density distributions of ethanol (solid line) and water (dashed line) on the TiO2 (left) and Pt (right) surfaces. Bottom: Relation between ln D(T) and reciprocal temperature in Kelvin: ethanol (solid line) and water (dashed line) in the presence of TiO2 (left) and Pt (right) surfaces.
