Effective stick-slip parameter for structurally lubric 2D interface friction
Jin Wang, Andrea Vanossi, Erio Tosatti
The wear-free sliding of layers or flakes of graphene-like 2D materials, important in many experimental systems, may occur either smoothly or through stick-slip, depending on drivi…
Rheological softening of metal nanocontacts sheared under oscillatory strains
Ali Khosravi, Jin Wang, Andrea Silva +2
The way metal interfaces evolve during frictional sliding, and how that evolution can be externally influenced under external drivers are important questions, hard to investigate e…
Current trends in the physics of nanoscale friction
N. Manini, G. Mistura, G. Paolicelli +2
Tribology, which studies surfaces in contact and relative motion, includes friction, wear, and lubrication, straddling across different fields: mechanical engineering, materials sc…
Electrical charging effects on the sliding friction of a model nano-confined ionic liquid
Rosario Capozza, Andrea Benassi, Andrea Vanossi +1
Recent measurements suggest the possibility to exploit ionic liquids (ILs) as smart lubricants for nano-contacts, tuning their tribological and rheological properties by charging t…
Squeezout phenomena and boundary layer formation of a model ionic liquid under confinement and charging
R. Capozza, A. Vanossi, A. Benassi +1
Electrical charging of parallel plates confining a model ionic liquid down to nanoscale distances yields a variety of charge-induced changes in the structural features of the confi…
Sliding Over a Phase Transition
Andrea Benassi, Andrea Vanossi, Giuseppe E. Santoro +1
The effects of a displacive structural phase transition on sliding friction are in principle accessible to nanoscale tools such as the Atomic Force Microscopy, yet they are still s…
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…
Nonlinear hysteretic behavior of a confined sliding layer
N. Manini, G. E. Santoro, E. Tosatti +1
A nonlinear model representing the tribological problem of a thin solid lubricant layer between two sliding periodic surfaces is used to analyze the phenomenon of hysteresis at pin…
Lubricated friction between incommensurate substrates
Andrea Vanossi, Giuseppe E. Santoro, Nicola Manini +2
This paper is part of a study of the frictional dynamics of a confined solid lubricant film - modelled as a one-dimensional chain of interacting particles confined between two idea…
Static friction on the fly: velocity depinning transitions of lubricants in motion
A. Vanossi, N. Manini, F. Caruso +2
The dragging velocity of a model solid lubricant confined between sliding periodic substrates exhibits a phase transition between two regimes, respectively with quantized and with…
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…
Melting and nonmelting of solid surfaces and nanosystems
U. Tartaglino, T. Zykova-Timan, F. Ercolessi +1
We present an extensive but concise review of our present understanding, largely based on theory and simulation work from our group, on the equilibrium behavior of solid surfaces a…
The effect of surface roughness on the adhesion of elastic solids
B. N. J. Persson, E. Tosatti
We study the influence of surface roughness on the adhesion of elastic solids. Most real surfaces have roughness on many different length scales, and this fact is taken into accoun…
Reentrant layering in rare gas adsorption: preroughening or premelting?
F. Celestini, D. Passerone, F. Ercolessi +1
The reentrant layering transitions found in rare gas adsorption on solid substrates have conflictually been explained either in terms of preroughening (PR), or of top layer melting…
DOF phase separation of the Lennard-Jones fcc(111) surface
C. S. Jayanthi, Franck Celestini, Furio Ercolessi +1
Recent lattice model calculations have suggested that a full-layered crystal surface may undergo, under canonical (particle-conserving) conditions, a preroughening-driven two-dimen…
