Analysis of lining force transmission coefficient and surrounding rock displacement in lined rock caverns for underground gas storage

Deep Underground Science and Engineering, EarlyView.
This study derives an explicit expression for the lining force transmission coefficient of underground gas storage lined rock caverns (LRCs) via the complex variable function method, considering the displacement release coefficient. Taking the 1‰ tensile strain of surrounding rock as the criterion to determine lining thickness, it systematically ...

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.

Closed‐form stress solution and minimum safe burial depth correction for shallow‐buried large‐diameter energy storage chambers

Deep Underground Science and Engineering, EarlyView.
This study develops a closed‐form solution for stress analysis of shallow‐buried large‐diameter compressed air energy storage (CAES) chambers, explicitly incorporating free surface, lateral pressure, and gravity gradient effects. Validated against numerical simulations, the solution accurately captures stress redistribution and reveals upward migration

Steel segment–anchor bolt (cable) structure for TBM tunnels under extremely intense rockburst conditions: Design method and field application

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a steel segment–anchorage support system for open TBM tunnels under extremely intense rockburst conditions. The steel segment resists dynamic impact, while the anchorage structure restrains segment deformation and transfers loads into the rock.

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 ...

Recent Advances in Ru‐Based Photothermal Catalysts: From Light Harvesting to Thermal Utilization and Reactor Design

EcoEnergy, EarlyView.
Overview of Ru‐based photothermal catalysis from light harvesting to heat utilization. The performance of Ru‐based photothermal catalysts is governed by four interconnected energy‐utilization steps: light harvesting, heat generation, heat retention, and heat utilization.

Decoupling environmental suitability from realized recruitment through ontogenetic environmental filtering in a long‐lived Mediterranean palm species

Ecography, EarlyView.
Long‐lived plants facing anthropogenic disturbance often exhibit recruitment failure despite persistent reproductive adults, generating extinction debt masked by longevity. However, whether adult presence reliably reflects environmental suitability for recruitment remains unclear.

A Synthetic Journey Toward Functional N‐Amidophenyl‐Substituted Hexaaza[16]paracyclophanes

European Journal of Organic Chemistry, EarlyView.
N‐amidophenyl‐substituted hexaaza[16]paracyclophanes can be synthesized via a convergent and efficient pathway, combining Ullmann and Buchwald–Hartwig coupling reactions. In accordance with simpler triarylamine molecules, these macrocyclic structures exhibit interesting light‐induced self‐assembling properties.
