Dynamic tensile strength and fracture evolution of characteristic shale with bedding and hole using linear regression theory

Deep Underground Science and Engineering, EarlyView.
The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

Deep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Phonon‐Driven Insights Into Layer Sliding of High‐Voltage Layered Cathode

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Understanding the structural instability of high‐voltage layered cathodes remains a critical challenge in advancing sodium‐ion batteries. This work proposes a breathing‐shear mode coupling model based on the phonon spectrum, which elucidates the layer sliding mechanism in layered cathode materials by using interlayer spacing as the order parameter.

Regulation of Oxygen Vacancies in High Entropy Oxides With Multi‐Layer Eggshell Architectural Framework for Boosting the Electrochemical Performance of Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An oxygen vacancy–rich FeZnCuCoNi high‐entropy oxide was constructed using a dual‐defect engineering strategy. This multi‐layer eggshell‐structured material delivers remarkable electrochemical performance, with high specific capacitance, excellent rate capability, and long‐term cycling stability even after 10 000 cycles.

Coherent Seismic Anisotropy Pattern Across Southern Africa Revealed by Shear Wave Splitting Measurements

Earth and Space Science
We report new PKS, SKS, and SKKS splitting measurements for 88 seismic stations in Namibia, Botswana, South Africa, and Mozambique. When combined with measurements from previous studies, the ensemble of measurements shows a fairly uniform NNE to NE (∼41°
