Effect of temperature and velocity on superlubricity
We study the effects of temperature and sliding velocity on superlubricity in numerical simulations of the Frenkel-Kontorova model. We show that resonant excitations of the phonons in an incommensurate sliding body lead to an effective friction and to thermal equilibrium with energy distributed over the internal degrees of freedom. For finite temperature, the effective friction can be described...
متن کاملRobust microscale superlubricity under high contact pressure enabled by graphene-coated microsphere
Superlubricity of graphite and graphene has aroused increasing interest in recent years. Yet how to obtain a long-lasting superlubricity between graphene layers, under high applied normal load in ambient atmosphere still remains a challenge but is highly desirable. Here, we report a direct measurement of sliding friction between graphene and graphene, and graphene and hexagonal boron nitride (h...
متن کاملSpatial Localization Accomplished by Sensitivity Heterogeneity
Introduction: Compared to single voxel spectroscopy, phase encoded chemical shift imaging (CSI) has the advantage of obtaining spectra from a rectangular array of voxels in a single study. However, long acquisition times are required to achieve reasonable spatial resolutions due to the time consuming phase encoding steps, which limits clinical applications of CSI. Hu et. al. (1) developed a tec...
متن کاملMacroscale Transformation Optics Enabled by Photoelectrochemical Etching.
Photoelectrochemical etching of silicon can be used to form lateral refractive index gradients for transformation optical devices. This technique allows the fabrication of macroscale devices with large refractive index gradients. Patterned porous layers can also be lifted from the substrate and transferred to other materials, creating more possibilities for novel devices.
متن کاملObservation of high-speed microscale superlubricity in graphite.
A sheared microscopic graphite mesa retracts spontaneously to minimize interfacial energy. Using an optical knife-edge technique, we report first measurements of the speeds of such self-retracting motion (SRM) from the mm/s range at room temperature to 25 m/s at 235°C [corrected]. This remarkably high speed is comparable with the upper theoretical limit found for sliding interfaces exhibiting s...
