The directional motion of sessile drops can be induced by slanted mechanical vibrations of
the substrate, which induce drop deformations combining both axisymmetric and …

Low power actuation of sessile droplets is of primary interest for portable or hybrid lab-on-a-
chip and harmless manipulation of biofluids. In this paper, we show that the acoustic power …

We investigate the spontaneous oscillations of drops levitated above an air cushion,
eventually inducing a breaking of axisymmetry and the appearance of “star drops”. This is …

In the Leidenfrost effect, a thin layer of evaporated vapour forms between a liquid and a hot
solid. The complex interactions between the solid, liquid and vapour phases can lead to rich …

Abstract Shear-thinning aqueous poly (3, 4-ethylenedioxythiophene): poly (styrene
sulphonate)(PEDOT: PSS) fluids were studied under the conditions of drop-on-demand …

Microdrop impact and spreading phenomena are explored as an interface formation process
using a recently developed computational framework. The accuracy of the results obtained …

We experimentally investigate the self-sustained, star-shaped oscillations of Leidenfrost
drops. The drops levitate on a cushion of evaporated vapor over a heated, curved surface …

A core unresolved challenge in rectified diffusion is the lack of predictive models, which
allow accurate modelling of the growth of bubbles over millions of cycles of oscillation. The …

Nonlinear axisymmetric shape oscillations of a Newtonian drop in a vacuum are
investigated theoretically, for fundamental interest and for their relevance in transport …

Nonlinear axisymmetric shape oscillations of an inviscid liquid drop in a vacuum are
investigated theoretically for their relevance for transport processes across the drop surface …
