Deep Underground Science and Engineering, EarlyView.This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

Deep Underground Science and Engineering, EarlyView.This graphical abstract presents a hierarchical adaptive strategy for selecting rheological models in intelligent backfill pipeline transportation. Temperature, fly ash content, and water‐cement ratio jointly influence slurry rheological nonlinearity, which is quantified using the Model Fidelity Gain (ΔR2).

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.
