About 30% of the world's primary energy consumption is in friction. The economic losses
caused by friction energy dissipation and wear account for about 2%–7% of its gross …

Current-carrying friction affects electrical contact systems like switches, motors, and slip
rings, which determines their performance and lifespan. Researchers have found that …

Dynamically controlling friction in micro-and nanoscale devices is possible using applied
electrical bias between contacting surfaces, but this can also induce unwanted reactions …

Mysteries about the origin of friction have remained for centuries. Especially, how friction is
tuned by an electric field is still unclear. Present tuning mechanisms mainly focus on the …

Friction properties in the electric field are important for the application of graphene as a solid
lubricant in graphene-based micro/nanoelectromechanical systems. The studies based on …

Atomically thin two-dimensional molybdenum disulfide (MoS2) is well known for its excellent
lubrication characteristics and is usually used as a solid lubricant in diverse micro …

This paper studies excitation-dependent energy dissipation in friction process under both
commensurate and incommensurate states between graphene layers. The results show that …

Friction is an energy dissipation process. However, the electronic contribution to energy
dissipation channels remains elusive during the sliding friction process. The friction and …

Nanofriction and nanoscale triboelectrification is a universally existing phenomenon and
important in many branches of nanotechnology, but how the nanoscale triboelectrification …

In dry sliding, the coefficient of friction depends on the material pair and contact conditions. If
the material and operating conditions remain unchanged, the coefficient of friction is …
