Formation of surface nanobubbles on nanostructured substrates

Nanoscale, 2017
The nucleation and stability of nanoscale gas bubbles located at a solid/liquid interface are attracting significant research interest. It is known that the physical and chemical properties of the solid surface are crucial for the formation and properties of the surface nanobubbles.

Enhanced fluctuation for pinned surface nanobubbles

Physical Review E, 2019
By employing molecular dynamics simulations we investigate the fluctuation of surface nanobubbles immersed in liquid phase. Our simulation results indicate that in comparison with the surrounding liquid and nanobubble interior, the vapor-liquid or gas-liquid interface of nanobubbles always exhibits the largest compressibility, demonstrating the ...

Dimensions and the Profile of Surface Nanobubbles: Tip–Nanobubble Interactions and Nanobubble Deformation in Atomic Force Microscopy

Langmuir, 2014
The interactions between argon surface nanobubbles and AFM tips on HOPG (highly oriented pyrolitic graphite) in water and the concomitant nanobubble deformation were analyzed as a function of position on the nanobubbles in a combined tapping mode and force-volume mode AFM study with hydrophilic and hydrophobic AFM tips.

Coarse-grained modelling of surface nanobubbles

Journal of Physics: Condensed Matter, 2013
Surface nanobubbles are nanoscale gaseous objects that form on hydrophobic surfaces in contact with water. Understanding nanobubble formation and stability remains challenging due to the lack of appropriate theoretical framework and adequate modelling. Here we present a non-equilibrium coarse-grained model for nanobubbles at hydrophobic surfaces.

Surface nanobubbles and micropancakes

Journal of Physics. Condensed Matter, 2016
When looking at a wetted surface with a technique that can probe the nanoscale, a high surface coverage of gas bubbles is often revealed. So what? Well, if we believe in classical diffusion, these bubbles should dissolve in microseconds, but in reality they are found to remain stable for as long as anyone has observed (five days thus far, which is 10 ...

Surface Nanobubbles with Fixed Boundaries

Technical Physics Letters, 2019
The formation and stability of surface-charged nanobubbles with fixed boundaries of substrate contact (so-called “pinning of contact lines”) was studied theoretically. Thermodynamic analysis showed that, for some sizes of nanobubbles, the Gibbs energy of the system goes through a minimum, which indicates the existence of equilibrium stable nanobubbles.
