Hydrodynamic Mechanism of Colloidal Propulsion through Momentum Exchange
Javier Diaz, Ignacio Pagonabarraga, Carles Calero
Propulsion of colloidal particles due to momentum transfer from localized surface reactions is investigated by solving the exact unsteady Stokes equation. We model the effect of su…

Colloidal Model for Investigating Optimal Efficiency in Weakly Coupled Ratchet Motors
José MartÃn-Roca, Laura Izquierdo-SolÃs, Fernando MartÃnez-Pedrero +3
We investigate the transport of superparamagnetic colloidal particles along self-assembled tracks using a periodically applied magnetic field as a model for ratchet-like mechanisms…

Enhancement of swimmer diffusion through regular kicks: analytic mapping of a scale independent parameter space
Arnau Jurado Romero, Carles Calero, Rossend Rey
Depending on their mechanism of self-propulsion, active particles can exhibit a time-dependent, often periodic, propulsion velocity. The precise propulsion velocity profile determi…
