Ballistic nanofriction
Roberto Guerra, Ugo Tartaglino, Andrea Vanossi +1
Sliding parts in nanosystems such as Nano ElectroMechanical Systems (NEMS) and nanomotors, increasingly involve large speeds, and rotations as well as translations of the moving su…
Dynamical chiral symmetry breaking in sliding nanotubes
X. H. Zhang, G. E. Santoro, U. Tartaglino +1
We discovered in simulations of sliding coaxial nanotubes an unanticipated example of dynamical symmetry breaking taking place at the nanoscale. While both nanotubes are perfectly…
Velocity plateaus and jumps in carbon nanotube sliding
Xiao-Hua Zhang, Ugo Tartaglino, Giuseppe E. Santoro +1
The friction between concentric carbon nanotubes sliding one inside the other has been widely studied and simulated, but not so far using external force as the driving variable. Ou…
Alkali Halide Surfaces Near Melting: Wetting and Nanofriction Properties
D. Ceresoli, T. Zykova-Timan, U. Tartaglino +1
Alkali halide (100) crystal surfaces are poorly wetted by their own melt at the triple point. We carried out simulations for NaCl(100) within the well tested BMHFT model potential.…
Gold Clusters Sliding on Graphite: a Possible Quartz Crystal Microbalance Experiment?
Stoyan Pisov, Erio Tosatti, Ugo Tartaglino +1
A large measured 2D diffusion coefficient of gold nanoclusters on graphite has been known experimentally and theoretically for about a decade. When subjected to a lateral force, th…
Impact of molecular structure on the lubricant squeeze-out between curved surfaces with long range elasticity
Ugo Tartaglino, Ion M. Sivebaek, Bo N. J. Persson +1
The properties of butane (C4H10) lubricants confined between two approaching solids are investigated by a model that accounts for the curvature and elastic properties of the solid…
