Capillary imbibition in lubricant coated channels
Sergi G. Leyva, Ignacio Pagonabarraga, Aurora Hernández-Machado +1
Capillary imbibition underpins many processes of fundamental and applied relevance in fluid mechanics. A limitation to the flow is the coupling to the confining solid, which induce…
Discontinuous transition in electrolyte flow through charge-patterned nanochannels
Tine Curk, Sergi G. Leyva, Ignacio Pagonabarraga
We investigate the flow of an electrolyte through a rigid nanochannel decorated with a surface charge pattern. Employing lattice Boltzmann and dissipative particle dynamics methods…
Hydrodynamics is Needed to Explain Propulsion in Chemophoretic Colloidal Rafts
Dolachai Boniface, Sergi G. Leyva, Ignacio Pagonabarraga +1
Active particles driven by a chemical reaction are the subject of intense research to date due to their rich physics, being intrinsically far from equilibrium, and their multiple t…
Clogging transition and anomalous transport in driven suspensions in a disordered medium
Sergi G. Leyva, Ignacio Pagonabarraga
We study computationally the dynamics of forced, Brownian particles through a disordered system. As the concentration of mobile particles and/or fixed obstacles increase, we charac…
Dynamics and Clogging of colloidal monolayers magnetically driven through an heterogeneous landscape
Sergi Granados Leyva, Ralph Lukas Stoop, Pietro Tierno +1
We combine experiments and numerical simulations to investigate the emergence of clogging in a system of interacting paramagnetic colloidal particles driven against a disordered la…
