Multiscale characterization of foams
Foam stability isan emergent multiscale property.
Foams are gas-in-liquid dispersions whose macroscopic properties emerge from a hierarchy of structures extending from molecular adsorption layers to thin liquid films, Plateau borders, bubbles and finally the complete foam column. Formation, drainage, coarsening, film thinning and rupture involve different physical mechanisms and occur over different time and length scales.
