| Abstract Scope |
It has been proved by experimental data and molecular dynamic simulation that the formation of nitrogen dense gas layer (DGL) between hydrophobic graphite and water. DGL is thought be explanation for the stability of nanobubbles and origin of hydrophobic force. In order to confirm whether this DGL is the ubiquitous phenomena, we expanded the research on more non-polar gases (Ar, O2, N2) and polar gas (CO2) between hydrophobic graphite solid surface/ hydrophilic NaCl solid surface and water. The results showed that DGLs formed for all non-polar gases while no DGLs formed for polar CO2 at graphite-water interface. For hydrophilic NaCl solid surface, no DGLs formed for polar or non-polar gases. |
