Molecular Dynamics Simulation of Imidazolium CnMIM-BF4 Ionic Liquids using a Coarse Grained Force-Field
Oscar Y. Fajardo, Silvia Di Lecce, Fernando Bresme
Ionic Liquids feature thermophysical properties that are of interest in solvents, energy storage materials and tenable lubrication applications. Recently, a series of coarse graine…
Electrotunable friction with ionic liquid lubricants: how important is the molecular structure of the ions?
O. Y. Fajardo, Fernando Bresme, Alexei A. Kornyshev +1
Using non-equilibrium molecular dynamics simulations and a coarse grained model of ionic liquids, we have investigated the impact that the shape and the intramolecular charge distr…
Lateral vibration effects in atomic-scale friction
R. Roth, O. Y. Fajardo, J. J. Mazo +2
The influence of lateral vibrations on the stick-slip motion of a nanotip elastically pulled on a flat crystal surface is studied by atomic force microscopy (AFM) measurements on a…
Out-of-plane and in-plane actuation effects on atomic-scale friction
O. Y. Fajardo, E. Gnecco, J. J. Mazo
The influence of out-of-plane and in-plane contact vibrations and temperature on the friction force acting on a sharp tip elastically pulled on a crystal surface is studied using a…
Thermal activation at moderate-to-high and high damping: finite barrier effects and force spectroscopy
J. J. Mazo, O. Y. Fajardo, D. Zueco
We study the thermal escape problem in the moderate-to-high and high damping regime of a system with a parabolic barrier. We present a formula that matches our numerical results ac…
Surface defects and temperature on atomic friction
Oscar Y. Fajardo, J. J. Mazo
We present a theoretical study of the effect of surface defects on atomic friction in the stick-slip dynamical regime of a minimalistic model. We focus on how the presence of defec…
