Off-equilibrium surface tension in miscible fluids

When two miscible fluids are brought in contact, an effective off-equilibrium surface tension arises that controls the shape and the evolution of their interface. We review more than a century of investigations of the effective surface tension in molecular and complex fluids.

Shape oscillations of particle-coated bubbles and directional particle expulsion

Ultrasound waves drive shape oscillations of particle-coated microbubbles. During the ultrafast, non-uniform deformation of the interface, particles are expelled from the antinodes of the shape oscillations.

Self-assembly of colloidal micelles in microfluidic channels

The self-assembly of amphiphilic Janus colloids in microfluidic channels under Poiseuille flow is studied using computer simulations. The aggregates grow in the weakly sheared channel center, whereas a distinct cluster breakup occurs in strongly sheared channel regions.

Self-assembly of repulsive interfacial particles via collective sinking

We consider how interactions between many floating, electrically charged particles modify the interaction energy: interfacial deformations due to many particles are larger than those of an isolated particle. This leads to a larger binding energy than would be expected based on the pair-wise interaction potential.
