Numerical simulations of self-diffusiophoretic colloids at fluid interfaces
T. Peter, P. Malgaretti, N. Rivas +3
The dynamics of active colloids is very sensitive to the presence of boundaries and interfaces which therefore can be used to control their motion. Here we analyze the dynamics of…
Self-diffusiophoresis induced by fluid interfaces
P. Malgaretti, M. N. Popescu, S. Dietrich
The influence of a fluid-fluid interface on self-phoresis of chemically active, axially symmetric, spherical colloids is analyzed. Distinct from the studies of self-phoresis for co…
Entropic electrokinetics: recirculation, particle separation and negative mobility
Paolo Malgaretti, Ignacio Pagonabarraga, J. Miguel Rubi
We show that when particles are suspended in an electrolyte confined between corrugated charged surfaces, electrokinetic flows lead to a new set of phenomena such as particle separ…
