Theoretical analysis of thermophoretic experimental data
J. M. Sancho
Thermophoresis is a transport phenomenon induced by a temperature gradient. Very small objects dispersed in a fluid medium and in a temperature gradient present a non homogeneous s…
A Tuneable Magnetic Domain Wall Conduit Regulating Nanoparticle Diffusion
Pietro Tierno, Tom H. Johansen, Jose M. Sancho
We demonstrate a general and robust method to confine on a plane strongly diffusing submicrometer particles in water by using size tunable magnetic channels. These virtual conduits…
Periodic spiking by a pair of ionic channels
Laureano Ramírez-Piscina, José M. Sancho
Neuronal cells present periodic trains of localized voltage spikes involving a large amount of different ionic channels. A relevant question is whether this is a cooperative effect…
Physical properties of voltage gated pores
Laureano Ramírez-Piscina, José M. Sancho
Experiments on single ionic channels have contributed to a large extent to our current view on the function of cell membrane. In these experiments the main observables are the phys…
Speeding chemical reactions by focusing
A. M. Lacasta, L. Ramirez-Piscina, J. M. Sancho +1
We present numerical results for a chemical reaction of colloidal particles which are transported by a laminar fluid and are focused by periodic obstacles in such a way that the tw…
Two-state flashing molecular pump
A. Gomez-Marin, J. M. Sancho
Here we study a pumping device capable of maintaining a density gradient and a flux of particles across a membrane. Its driving mechanism is based on the flashing ratchet effect po…
