Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

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.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

EcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Recovery and Repurposing of End‐of‐Life Graphitic Anodes for Green Lithium‐Ion Batteries

EcoEnergy, EarlyView.
This review summarizes the degradation mechanisms of spent graphite anodes in lithium‐ion batteries and highlights key recycling, regeneration, and modification strategies, including hydrometallurgical and pyrometallurgical approaches. It also discusses recent advances in surface engineering, structural regulation, and material hybridization, offering ...
