WebOct 2, 2013 · Variations in atomic surfaces are thought to modulate the force of friction in a way that depends on the direction in which objects are moved, but this has been difficult to show experimentally. WebJun 4, 1998 · This article will review recent theoretical and experimental studies of friction processes at the atomic scale. Theoretical …
Resonance in Atomic-Scale Sliding Friction
WebApr 14, 2024 · The static friction force corresponds to the step position (i.e., 9 nJ in Fig. 2c), while the sliding friction force corresponds to the E-intercept of the linear approximation (7.8 nJ). WebApr 4, 2007 · Atomic force microscopy (AFM) experiments and molecular dynamics (MD) simulations were conducted to examine single-asperity friction as a function of load, surface orientation, and sliding direction on individual crystalline grains of diamond in the wearless regime. Experimental and simulation conditions were designed to correspond as closely … marcelle vente
Nanotribology: friction, wear and lubrication at the atomic …
WebAt the atomic scale, friction becomes a mechanism that converts the kinetic energy associated with the relative motion of surfaces to thermal energy. However, the description of the conversion to thermal energy represented by a disordered state of oscillations of atoms in a solid is still not well understood. At the macroscopic level, friction ... WebJul 14, 2006 · The effect of a sinusoidal excitation at f = 56.7 kHz on atomic-scale friction on NaCl is shown ( Fig. 1, A and B ). When the excitation is switched on, the … WebNov 11, 2024 · The term was first introduced by Professor Hirano in the 1990 who carefully considered the details of the friction at the atomic scale. Professor Hirano theoretically predicted the existence of a physical state where friction can nearly vanish in case if the sliding interface is made of surfaces that are atomically flat, rigid, incommensurate ... marcelle verelle
