Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Spatially Configuring RGO Interlayers With PANI/Lignin Nanoparticles Toward High‐Performance Asymmetric Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel PLNPs@RGO electrode, self‐assembled from polyaniline/lignin conjugated mesoporous nanoparticles (PLNPs) and reduced graphene oxide, exhibits excellent capacitance and high energy density in supercapacitors. The high‐performance flexible solid‐state asymmetric supercapacitor (FSAC) plays a critical role in advancing the innovation of next ...

Boosting Photocatalytic H2O2 Synthesis Over HKUST‐1 MOFs‐Derived Hollow HKUST‐1@CuFePBA@CuS Heterojunctions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Photoelectron transfer mechanism and photocatalytic O2‐to‐H2O2 reduction process over hollow HS@CuFe@CuS heterojunction photocatalysts. Recently, photocatalytic synthesis of H2O2 has received much attention. However, the photocatalytic activity of photocatalysts is generally limited due to multiple factors, such as insufficiency of photoelectrons, low ...
