Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Dynamic Active Site Mechanism and Compositional Tuning in LaxSr1−xCoyFe1−yO3 (LSCF) Perovskites Toward Efficient Oxygen Evolution

EcoEnergy, EarlyView.
A dynamic active site mechanism through cooperative metal–lattice oxygen interactions enables efficient oxygen evolution in LSCF perovskites without relying on oxygen vacancy formation, where the La/Sr ratio governs the intrinsic activity of LSCF and Co incorporation provides secondary enhancement, establishing a general composition‐guided paradigm for

Enhancing Anode‐Free Lithium Metal Batteries: A Lightweight MPTS‐MXene Current Collector for Superior Performance and Energy Density

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces an MPTS‐modified MXene current collector for anode‐free lithium metal batteries (AFLMBs). A key advantage of MPTS‐MXene is its ultralight weight, only 15% as heavy as standard copper per unit volume. Its special layered structure and Si‐O rich surface help lithium deposit smoothly and flat, while forming a protective layer that ...

Exploring Cultural and Individual Differences in the Hierarchy of Moral Concern: Evidence From Student Samples Across 41 Cultural Groups

European Journal of Social Psychology, EarlyView.
ABSTRACT Many important historical and contemporary ethical debates (e.g., on slavery, abortion and environmental protection) reflect disagreements about what we owe to different groups of individuals. Recent work in moral psychology has uncovered a seemingly replicable hierarchy of moral concern, but these studies were conducted in a few countries ...
