Self-chemophoresis in the thin diffuse interface approximation
Alvaro DomÃnguez, Mihail N. Popescu
Self-chemophoresis is an appealing and quite successful interpretation of the motility exhibited by certain chemically active colloidal particles suspended in a solution of their "…

Chemotactic behavior for a self-phoretic Janus particle near a patch source of fuel
Viviana Mancuso, Mihail N. Popescu, William E. Uspal
Many biological microswimmers are capable of chemotaxis, i.e., they can sense an ambient chemical gradient and adjust their mechanism of motility to move towards or away from the s…

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…
