Steady translation of a chemically active viscous drop along a rigid wall
Nikhil Desai, Sébastien Michelin
Chemically active drops release a chemical solute, gradients in whose concentration cause interfacial flows that advect the emitted solute. This non-linear coupling between solute…
Colloidal bubble propulsion mediated through viscous flows
Alexander Chamolly, Sébastien Michelin, Eric Lauga
Bubble-propelled catalytic colloids stand out as a uniquely efficient design for artificial controllable micromachines, but so far lack a general theoretical framework that explain…
Steady state propulsion of isotropic active colloids along a wall
Nikhil Desai, Sebastien Michelin
Active drops emit/absorb chemical solutes, whose concentration gradients cause interfacial flows driving their own transport and the propulsion of the droplet. Such non-linear coup…
Self-propulsion of chemically-active droplets
Sebastien Michelin
Microscopic active droplets are able to swim autonomously in viscous flows: this puzzling feature stems from solute exchanges with the surrounding fluid via surface reactions or th…
Instability and self-propulsion of active droplets along a wall
Nikhil Desai, Sebastien Michelin
Active droplets can swim spontaneously in viscous flows as a result of the non-linear convective transport of a chemical solute produced at their surface by the Marangoni and/or ph…
Hydrochemical interactions of phoretic particles: a regularized multipole framework
Francisco Rojas-Perez, Blaise Delmotte, Sebastien Michelin
Chemically-active colloids modify the concentration of chemical solutes surrounding them in order to self-propel. In doing so, they generate long-ranged hydrodynamic flows and chem…
