Spontaneous onset of convection in a uniform phoretic channel
Sébastien Michelin, Simon Game, Eric Lauga +2
Phoretic mechanisms, whereby gradients of chemical solutes induce surface-driven flows, have recently been used to generate directed propulsion of patterned colloidal particles. Wh…
Modeling chemo-hydrodynamic interactions of phoretic particles: a unified framework
Akhil Varma, Sebastien Michelin
Phoretic particles exploit local self-generated physico-chemical gradients to achieve self-propulsion at the micron scale. The collective dynamics of a large number of such particl…
Orientational instability and spontaneous rotation of active nematic droplets
Matvey Morozov, Sebastien Michelin
In experiments, an individual chemically active liquid crystal (LC) droplet submerged in the bulk of a surfactant solution may self-propel along a straight, helical, or random traj…
Universal optimal geometry of minimal phoretic pumps
Sebastien Michelin, Eric Lauga
Unlike pressure-driven flows, surface-mediated phoretic flows provide efficient means to drive fluid motion on very small scales. Colloidal particles covered with chemically-active…
Nonlinear dynamics of a chemically-active drop: from steady to chaotic self-propulsion
Matvey Morozov, Sebastien Michelin
Individual chemically active drops suspended in a surfactant solution were observed to self-propel spontaneously with straight, helical, or chaotic trajectories. To elucidate how t…
Phoretic and hydrodynamic interactions of weakly-confined autophoretic particles
Eva Kanso, Sebastien Michelin
Phoretic particles self-propel using self-generated physico-chemical gradients at their surface. Within a suspension, they interact hydrodynamically by setting the fluid around the…
