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.

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

open access: yesEcography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...

Dual‐Enhancement Strategy for OER via Ni–Co–Fe Tri‐Level Electron Regulation and La‐Assisted Structural Stabilization: LaFe Selective Coating on CoCH/NF Precatalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic dual‐modulation strategy integrates Ni activation via stepwise electronic regulation and La‐induced stabilization during electrochemical reconstruction. The hierarchical LaFe–CoCH/NF precursor transforms into a robust La/NiCoFeOOH interface, delivering optimized electronic structure, high turnover frequency (TOF400 = 1.23 s⁻¹), and ...
