Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

Deep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

Deep Underground Science and Engineering, EarlyView.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Redox‐Mediating Mo2C Nanoparticles Confined Within Nitrogen‐ and Phosphorus‐Codoped Amorphous Carbon Matrix for Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional interlayer composed of Mo2C nanoparticles embedded in a nitrogen‐ and phosphorus‐doped amorphous carbon matrix on graphene is developed via electrostatic self‐assembly and thermal transformation. The resulting architecture suppresses the shuttle effect, improves electrical conductivity, and facilitates redox conversion kinetics ...

Synergistic SnSe2@Ti3C2Tx MXene Heterostructured Separator for Highly Efficient Polysulfide Adsorption, Catalytic Redox Acceleration, and Enhanced Electrochemical Stability in Advanced Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional SnSe2@MXene heterostructure coated on a separator serves as a catalytic interlayer in Li‐S batteries. This design synergistically integrates the strong polysulfide adsorption and catalytic activity of SnSe2 with the high electrical conductivity of the MXene matrix, effectively suppressing the shuttle effect and enabling long‐term ...
