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…

Geometrically-tuned channel permeability

Paolo Malgaretti, Ignacio Pagonabarraga, J. Miguel Rubi

We characterize the motion of charged as well as neutral tracers, in an electrolyte embedded in a varying section channel. We exploit a set of systematic approximations that allows…

Entropic electrokinetics: recirculation, particle separation and negative mobility

Paolo Malgaretti, Ignacio Pagonabarraga, J. Miguel Rubi

We show that when particles are suspended in an electrolyte confined between corrugated charged surfaces, electrokinetic flows lead to a new set of phenomena such as particle separ…

Protein motors induced enhanced diffusion in intracellular transport

I. Santamaria-Holek, M. H. Vainstein, J. M. Rubi +1

Diffusion of transported particles in the intracellular medium is described by means of a generalized diffusion equation containing forces due to the cytoskeleton network and to th…

Finite-size effects in intracellular microrheology

I. Santamaria-Holek, J. M. Rubi

We propose a model to explain finite-size effects in intracellular microrheology observed in experiments. The constrained dynamics of the particles in the intracellular medium, tre…

Kinetics of growth process controlled by mass-convective fluctuations and finite-size curvature effects

A. Gadomski, J. Siodmiak, I. Santamaria-Holek +2

In this study, a comprehensive view of a model crystal formation in a complex fluctuating medium is presented. The model incorporates Gaussian curvature effects at the crystal boun…
