Active systems have been a matter of great interest across various scientific disciplines
owing to the host of potential applications. While bulk active matter systems have received a …

The methods to study capillary waves have been reviewed together with the emerging
practical applications of theirs and new theoretical developments in the field. The focus is on …

Measurements of liquid surface topography are performed using new modification of
Background Oriented Schlieren technique, which is based on the apparent distortion of a …

The capillary wave method is a well-known classical technique to measure surface tension
and surface rheological properties. Despite the large number of theoretical works devoted to …

Surface tension is a material property that is needed to describe fluid behaviour, which
impacts industrial processes, in which molten material is created, such as thermal cutting …

Materials adsorbed onto the surface of a fluid–for instance, crude oil, biogenic slicks or
industrial/medical surfactants–will move in response to surface waves. Owing to the difficulty …

One of the most significant sources of water wastage in Australia is loss from small storage
dams, either by seepage or evaporation. Over much of Australia, evaporative demand …

When a drop of aqueous surfactant solution is placed on a deep subphase of water, multiple
phenomena occur. The contact line of the drop spreads until the drop merges with the …

We use Faraday waves to measure interfacial tension σ between two immiscible fluids, with
an interest in (ultra) low values of σ. The waves are excited by vertically oscillating the …

Spreading of water drops resting in equilibrium on polypropylene surfaces was initiated by
dispensing surfactant-laden droplets on their apex. Upon contact of the two drops two …
