Active spheres induce Marangoni flows that drive collective dynamics
Martin Wittmann, Mihail N. Popescu, Alvaro Domínguez +1
For monolayers of chemically active particles at a fluid interface, collective dynamics are predicted to arise owing to activity-induced Marangoni flow even if the particles are no…
Self-motility of an active particle induced by correlations in the surrounding solution
Alvaro Domínguez, M. N. Popescu, C. M. Rohwer +1
Current models of phoretic transport rely on molecular forces creating a "diffuse" particle-fluid interface. We investigate theoretically an alternative mechanism, in which a diffu…
Floor- or ceiling-sliding for chemically active, gyrotactic, sedimenting Janus particles
Sayan Das, Zohreh Jalilvand, Mihail N. Popescu +3
Surface bound catalytic chemical reactions self-propel chemically active Janus particles. In the vicinity of boundaries, these particles exhibit rich behavior, such as the occurren…
Phase coexistence in a monolayer of active particles induced by Marangoni flows
Alvaro Domínguez, Mihail N. Popescu
Thermally or chemically active colloids generate thermodynamic gradients in the solution in which they are immersed and thereby induce hydrodynamic flows that affect their dynamica…
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…
Collective dynamics of chemically active particles trapped at a fluid interface
Alvaro Domínguez, P. Malgaretti, M. N. Popescu +1
Chemically active colloids generate changes in the chemical composition of their surrounding solution and thereby induce flows in the ambient fluid which affect their dynamical evo…
