Superlubricity achieved with two-dimensional nano-additives to liquid lubricants

open access: yesFriction, 2020
The topic of superlubricity is attracting considerable interest around the world while humanity is facing an energy crisis. Since various liquid superlubricity systems can be commonly achieved on the macroscale in ambient conditions, it is considered an ...

High‐Performance Self‐Powered Sensing System for Power Grid Applications

open access: yesAdvanced Sensor Research, Volume 5, Issue 3, March 2026.
This study presents a lateral swing electromagnetic generator (LS‐EMG) for harvesting overhead transmission line vibration energy. With a compact 24.32 cm3 volume, it achieves 2.28 mW output power and 93.75 µW/cm3 power density. A self‐powered wireless sensor system was developed using this generator, enabling real‐time temperature and humidity ...

Influence Factors on Mechanisms of Superlubricity in DLC Films: A Review

open access: yesFrontiers in Mechanical Engineering, 2020
As a kind of self-lubricating material, diamond-like carbon (DLC) film is famous for its excellent tribological properties. Superlubricity state with nearly-vanishing friction achieved with DLC film has enormous potential applications in future ...

Macroscale Superlubricity Accomplished by Sb2O3-MSH/C Under High Temperature

open access: yesFrontiers in Chemistry, 2021
Here, we report the high-temperature superlubricity phenomenon accomplished in coatings produced by burnishing powders of antimony trioxide (Sb2O3) and magnesium silicate hydroxide coated with carbon (MSH/C) onto the nickel superalloy substrate.

Interlayer shear strength of single crystalline graphite

open access: yes, 2012
Reported values (0.2 MPa ~ 7.0 GPa) of the interlayer shear strength (ISS) of graphite are very dispersed. The main challenge to obtain a reliable value of ISS is the lack of precise experimental methods.

Achieving macroscale superlubricity with ultra-short running-in period by using polyethylene glycol-tannic acid complex green lubricant

open access: yesFriction, 2023
Superlubricating materials can greatly reduce the energy consumed and economic losses by unnecessary friction. However, a long pre-running-in period is indispensable for achieving superlubricity; this leads to severe wear on the surface of friction pairs

Static and Dry Friction due to Multiscale Surface Roughness

open access: yes, 2008
It is shown on the basis of scaling arguments that a disordered interface between two elastic solids will quite generally exhibit static and "dry friction" (i.e., kinetic friction which does not vanish as the sliding velocity approaches zero), because of
