Rubber friction on wet and dry road surfaces: the sealing effect
B. N. J. Persson, U. Tartaglino, O. Albohr +1
Rubber friction on wet rough substrates at low velocities is typically 20-30% smaller than for the corresponding dry surfaces. We show that this cannot be due to hydrodynamics and…
On the nature of surface roughness with application to contact mechanics, sealing, rubber friction and adhesion
B. N. J. Persson, O. Albohr, U. Tartaglino +2
Surface roughness has a huge impact on many important phenomena. The most important property of rough surfaces is the surface roughness power spectrum C(q). We present surface roug…
Sealing is at the Origin of Rubber Slipping on Wet Roads
B. N. J. Persson, U. Tartaglino, O. Albohr +1
Loss of braking power and rubber skidding on a wet road is still an open physics problem, since neither the hydrodynamical effects nor the loss of surface adhesion that are sometim…
Electronic friction and liquid-flow-induced voltage in nanotubes
B. N. J. Persson, U. Tartaglino, E. Tosatti +1
A recent exciting experiment by Ghosh et al. reported that the flow of an ion-containing liquid such as water through bundles of single-walled carbon nanotubes induces a voltage in…
Boundary Lubrication: Squeeze-out Dynamics of a Compressible 2D Liquid
U. Tartaglino, B. N. J. Persson, A. I. Volokitin +1
The expulsion dynamics of the last liquid monolayer of molecules confined between two surfaces has been analyzed by solving the two-dimensional (2D) Navier-Stokes equation for a co…
