Non-Equilibrium Molecular Dynamics Study on Velocity-Dependent Threshold Behavior of Wearless Nano-Friction
In order to develop methods of designing arti cial materials of desired tribological characteristics for nano-electromechanical systems (NEMS), a better atomistic understanding of wearless-frictional characteristics of mesoscopic solid materials is indispensable. We have searched for laws of wearless friction accompanying steady sliding motion between mesoscopic crystal lattices, by molecular d...
متن کاملMolecular dynamics study on velocity-dependent threshold behavior of wearless nano-friction
A law of friction accompanying steady sliding motion between crystal lattices constituting a nano-electromechanical system (NEMS) was revealed by molecular dynamics simulations using simplified models. A threshold phenomenon was predicted as a common feature characterizing dependence of the wearless-frictional resistance on the sliding velocity vstroke. The threshold sliding velocity vth almost...

متن کاملSeasonal dynamics of threshold friction velocity and dust emission in Central Asia
An improved model representation of mineral dust cycle is critical to reducing the uncertainty of dust-induced environmental and climatic impact. Here we present a mesoscale model study of the seasonal dust activity in the semiarid drylands of Central Asia, focusing on the effects of wind speed, soil moisture, surface roughness heterogeneity, and vegetation phenology on the threshold friction v...

Based on molecular dynamics search for laws of wearless friction accompanying steady sliding motion between mesoscopic crystal lattices, we have been developing Phonon-Band Engineering approaches [1] to design arti cial materials of desired tribological characteristics for nano-electromechanical systems (NEMS) by utilizing the up-to-date nano-fabrication technology. In the present study, we r...
