Query: Stability of Surface Nanobubbles: A Molecular Dynamics Study   The stability and growth or dissolution of a single surface nanobubble on a
chemically patterned surface are studied by Molecular Dynamics (MD) simulations
of binary mixtures consisting of Lennard-Jones (LJ) particles. Our simulations
reveal how pinning of the three-phase contact line on the surface can lead to
the stability of the surface nanobubble, provided that the concentration of the
dissolved gas is oversaturated. We have performed equilibrium simulations of
surface nanobubbles at different gas oversaturation levels $\zeta>0$. The
equilibrium contact angle $\theta_e$ is found to follow the theoretical result
of Lohse and Zhang (Phys. Rev. E 2015, 91, 031003(R)), namely $\sin\theta_e =
\zeta L/L_c$, where L is the pinned length of the footprint and $L_c =
4\gamma/P_0$ a capillary length scale, with $\gamma$ the surface tension and
$P_0$ the ambient pressure. For undersaturation $\zeta<0$ the surface
nanobubble dissolves and the dissolution dynamics shows a "stick-jump"
behaviour of the three-phase contact line.
