Electroneutrality breakdown for electrolytes embedded in varying-section nanopores
P. Malgaretti, I. Pagonabarraga, J. Harting
We determine the local charge dynamics of a electrolyte embedded in a varying-section channel. By means of an expansion based on the length scale separation between the axial…
Surface viscosity in simple liquids
Paolo Malgaretti, Ubaldo Bafile, Renzo Vallauri +2
The response of Newtonian liquids to small perturbations is usually considered to be fully described by homogeneous transport coefficients like shear and dilatational viscosity. Ho…
Splitting probabilities for dynamics in corrugated channels: passive VS active Brownian motion
P. Malgaretti, T. Nizkaia, G. Oshanin
In many practically important problems which rely on particles' transport in realistic corrugated channels, one is interested to know the probability that either of the extremities…
Numerical simulations of self-diffusiophoretic colloids at fluid interfaces
T. Peter, P. Malgaretti, N. Rivas +3
The dynamics of active colloids is very sensitive to the presence of boundaries and interfaces which therefore can be used to control their motion. Here we analyze the dynamics of…
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…
Rectification and non-Gaussian diffusion in heterogeneous media
Paolo Malgaretti, Ignacio Pagonabarraga Miguel J. Rubi
We show that when Brownian motion takes place in a heterogeneous medium, the presence of local forces and transport coefficients leads to deviations from a Gaussian probability dis…
