<< the nucleation mechanism of spontaneously generated NBs (nanobubbles) at solid-liquid interfaces of immersed nanostructured hydrophobic surfaces is studied. Depending on the size and density of the surface nanostructures, NBs with different size and density were reproducibly and deterministically obtained. >>️
moreover, << air entrapment experiments on a porous PS (coated polystyrene) surface covered with irregular nanopores show that also the shape of NBs can also be tuned by surface nanostructures, due to their pinning effect. It is thus feasible to tune NB size, position, and even morphology by varying surface nanostructures. >>️
