Shape dependent phoretic propulsion of slender active particles
Yahaya Ibrahim, Ramin Golestanian, Tanniemola B. Liverpool
We theoretically study the self-propulsion of a thin (slender) colloid driven by asymmetric chemical reactions on its surface at vanishing Reynolds number. Using the method of matc…
Multiple phoretic mechanisms in the self-propulsion of a Pt-insulator Janus swimmer
Yahaya Ibrahim, Ramin Golestanian, Tanniemola B. Liverpool
We present a detailed theoretical study which demonstrates that electrokinetic effects can also play a role in the motion of metallic-insulator spherical Janus particles. Essential…
How walls affect the dynamics of self-phoretic microswimmers
Yahaya Ibrahim, Tanniemola B. Liverpool
We study the effect of a nearby planar wall on the propulsion of a spherical phoretic micro-swimmer driven by reactions on its surface. An asymmetric coverage of catalysts on its s…
The dynamics of a self-phoretic Janus swimmer near a wall
Yahaya Ibrahim, Tanniemola B. Liverpool
We study the effect of a nearby planar wall on the propulsion of a phoretic Janus micro-swimmer driven by asymmetric reactions on its surface which absorb reactants and generate pr…
Electrokinetic Effects in Catalytic Pt-Insulator Janus Swimmers
S. Ebbens, D. A. Gregory, G. Dunderdale +4
The effect of added salt on the propulsion of Janus platinum-polystyrene colloids in hydrogen peroxide solution is studied experimentally. It is found that micromolar quantities of…
