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.

Interface‐Sensitized ZnO/WS2 Heterostructures: Surface‐Activated Porous Sensitizers for Robust Chemiresistive Gas Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced NO2 sensing mechanism of the P‐ZnO/WS2 heterostructure, emphasizing the role of the porous architecture and abundant chemisorbed oxygen species in P‐ZnO nanocubes, which facilitate interfacial charge transfer to WS2 nanoflakes. Hybridizing transition metal dichalcogenides with metal oxides offers a viable route to overcome their intrinsically ...

How Social Media Connects and Divides Us: Psychological Insights and Paths Forward

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Social media was once celebrated as a revolutionary space for constructive connection. While it can foster community, amplify marginalised voices and expose users to diverse perspectives, these platforms are also implicated in the rise of polarisation, intergroup conflict and extremist movements.
