Molecular Dynamics Simulation on Stability of Vapor Nanobubbles

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 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...

Investigation of Melting by Molecular Dynamics Simulation

The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...

Molecular Dynamics Simulation of nanobubbles in the bulk and on the substrate

Nanobubbles are considered to be one origin of characteristic behaviors of fluids in microscopic systems, such as boundary slip in channels and long-range attractive force acting between hydrophobic surfaces. In many recent experiments, nanobubbles on the hydrophobic substrates are observed with atomic force microscopy , infrared spectroscopy and other techniques. Observed nanobubbles are extra...

Molecular dynamics simulation of supersaturated vapor nucleation in slit pore

Molecular dynamics study on helium nanobubbles in water.

Interfacial properties of helium nanobubbles in water at normal conditions have been investigated using large-scale molecular dynamics simulations for systems including over one million atoms. The surface tension of a helium nanobubble is a convex function with respect to the bubble radius, and is estimated to vanish at a critical radius of approximately 1 nm.
