Thin liquid films arise in many technological applications and biological phenomena. They
also present a fascinating object of study, because of a rich interplay between capillarity …

The coalescence and break-up of bubbles are important steps in many industrial processes.
To date, most of the literature has been focussed on the coalescence process which has …

Foams and antifoams are two entities with completely different natures. For example, the
foams are structures of bubbles in contact, while the antifoams are emulsions containing …

Bubble coalescence experiments have been performed using a sliding bubble apparatus, in
which mm-sized bubbles in an aqueous electrolyte solution without added surfactant rose …

The electrocoalescence behavior of surfactant-laden droplet pairs in oil under a DC electric
field was investigated in this paper. The characteristic parameters such as coalescence time …

The dynamics of thin films containing polymer solutions are studied with a pressure-
controlled thin film balance. The setup allows the control of both the magnitude and the sign …

Foams can resist destabilizaton in ways that appear similar on a macroscopic scale, but the
microscopic origins of the stability and the loss thereof can be quite diverse. Here, we …

This review presents a summary of the results in the domain of microscopic liquid film
hydrodynamics for several decades of experimental and theoretical research. It mainly …

The mineral processing industry relies heavily on froth flotation to beneficiate complex
minerals. The performance of the process depends on a multitude of chemical reagents …

We have developed a methodology that can be used to determine disjoining pressures (Π)
in both stable and unstable wetting films from the spatial and temporal profiles of dynamic …
