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…
Adhesive contact of rough surfaces: comparison between numerical calculations and analytical theories
Giuseppe Carbone, Michele Scaraggi, Ugo Tartaglino
We have employed a numerical procedure to analyze the adhesive contact between a soft elastic layer and a rough rigid substrate. The solution of the problem is obtained by calculat…
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…
Nanodroplets on rough hydrophilic and hydrophobic surfaces
C. Yang, U. Tartaglino, B. N. J. Persson
We present results of Molecular Dynamics (MD) calculations on the behavior of liquid nanodroplets on rough hydrophobic and hydrophilic solid surfaces. On hydrophobic surfaces, the…
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.…
