Gas adsorption and accumulation on hydrophobic surfaces: Molecular dynamics simulations
Luo Qing-Qun, Yang Jie-Ming†
       
Density distributions of system, water, and gas at 40 ps obtained by simulation of Case 4. In the depletion layer, the density of gas increases significantly and the density of water decreases; however, adjoining the depletion layer, the density of gas decreases significantly and the density of water increases significantly. In addition, the fluctuations in the gas density in the bulk water increase.
