Electrode structures of solid–liquid interface‐based triboelectric nanogenerators and their applications

open access: yesDroplet, EarlyView.
In this review, we have summarized the working principles and equivalent circuit diagrams of solid‐liquid interface triboelectric nanogenerators with different electrode structures, as well as the applications of devices with such structures in droplet mechanical energy harvesting and self‐powered sensing of liquid samples, along with their respective ...

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

open access: yesDeep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.
