Hydrodynamic Stokes flow induced by a chemically active patch imprinted on a planar wall
Mihail N. Popescu, Bogdan Adrian Nicola, William E. Uspal +2
Patches of catalyst imprinted on supporting walls induce motion of the fluid around them once they are supplied with the chemical species (``fuel'') that are converted by the catal…

Force-dependence of the rigid-body motion for an arbitrarily shaped particle in a forced, incompressible Stokes flow
Alvaro DomÃnguez, Mihail N. Popescu
When a particle moves in a Newtonian flow at low Reynolds number, inertia is irrelevant and a linear relationship exists between velocities and forces. For incompressible flows, an…

Ionic self-phoresis maps onto correlation-induced self-phoresis
Alvaro DomÃnguez, Mihail N. Popescu
We re-examine the self-phoresis of a particle that releases(removes) pairs of ions into(from) the electrolyte solution. We show analytically that in the linear regime the mathemati…
