The oil resistivity of aqueous foam is a significant property in many industrial fields. This
work aims at studying on oil resistivity of foams generated by mixtures of fluorocarbon and …

Ultrathin foam films containing supramolecular structures like micelles in bulk and adsorbed
surfactant at the liquid–air interface undergo drainage via stratification. At a fixed surfactant …

Freshly formed soap films, soap bubbles, or foam films display iridescent colors due to thin
film interference that changes as squeeze flow drives drainage and a progressive decrease …

The stability and thinning behaviour of the liquid foam film containing fluorocarbon and
hydrocarbon surfactant mixtures were investigated quantitatively by using the optical …

For a long time, the phenomenon known as the “tears of wine” was believed to be due only
to the surface tension gradient (eg, the Thomson-Marangoni stress on the fluid/fluid surface's …

Freestanding films of soft matter drain via stratification due to confinement-induced
structuring and layering of supramolecular structures such as micelles. Neutral polymers …

Abstract Hypothesis The superchaotropic Keggin polyoxometalate α-SiW 12 O 40 4−(SiW)
was recently shown to stabilize non-ionic surfactant (C 18: 1 E 10) foams owing to …

Ultrathin foam films (thickness, h< 100 nm) containing micelles undergo drainage via
stratification manifested as coexisting thick–thin flat regions, nanoscopic non-flat …

Sodium naphthenates (NaNs), found in crude oils and oil sands process-affected water
(OSPW), can act as surfactants and stabilize undesirable foams and emulsions. Despite the …

Bile salts, especially in their aggregated or micellar form, play a critical role in health and
medicine by solubilizing cholesterol, fat-soluble vitamins, and drugs. However, in contrast to …
