Surface forces and wetting features in drops and capillaries
journal contribution
posted on 2017-07-18, 10:26 authored by M.G. Velarde, Victor StarovUsing the DLVO (Derjaguin, Landau, Verwey, Overbeek) theory, which accounts for quantum mechanics and electrostatics at the macroscopic level, the thermodynamic expressions for (thermodynamic) equilibrium contact angles of drops on solid substrates and menisci in solid wall capillaries are, operationally and unambiguously, expressed in terms of the corresponding Derjaguin pressure.
The latter’s S-shape is responsible for microdrops and other phenomena appearing on flat solid substrates.
