Investigation of the Stability of Liquid and Air Films by Synchronized Tri-Wavelength Reflection Interferometry Microscope

“…Molybdenite's basal plane has sulfur elements exposed on its surface. When immersed in water, molybdenite's basal surface exhibits natural hydrophobicity 43 . All of these hydrophobic surfaces exhibit a critical rupture distance of less than 300 nm when in close proximity to a water droplet.…”

“…These two factors result in a small deformation. The interfacial deformation of the TLFs under an influence of both hydrodynamic and surface forces has been numerically modelled using a combination of the lubrication theory and Young-Laplace equation, 43,61 and thus will not be discussed in the present work.…”
