Thin liquid films: Where hydrodynamics, capillarity, surface stresses and intermolecular forces meet

Thin liquid films arise in many technological applications and biological phenomena. They also present a fascinating object of study, because rich interplay between capillarity, hydrodynamics, interfacial transport phenomena rheology, as well the effects interaction forces when thin down to molecular thicknesses. Recent advances experimental techniques have given further insights variety physical phenomena, which can occur. These are briefly reviewed. How these be utilised is illustrated by recent studies addressing effect rheological stresses on drainage, capillarity hydrodynamics during film retraction, solutocapillary stabilisation films. Finally, we discuss challenges conducting drainage measurements at high varied capillary numbers how could overcome combined use experiments simulations.
