Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

open access: yesDeep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

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

open access: yesDeep 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 ...

Enhancing Anode‐Free Lithium Metal Batteries: A Lightweight MPTS‐MXene Current Collector for Superior Performance and Energy Density

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces an MPTS‐modified MXene current collector for anode‐free lithium metal batteries (AFLMBs). A key advantage of MPTS‐MXene is its ultralight weight, only 15% as heavy as standard copper per unit volume. Its special layered structure and Si‐O rich surface help lithium deposit smoothly and flat, while forming a protective layer that ...

Electrospun Biomass‐Derived Flexible Anodes With Hierarchical Structure via Cobalt MOF Integration for Sodium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Hierarchically porous, N‐doped freestanding anode enables reversible Na+ insertion/desorption and Na–Co alloying, delivering fast kinetics, structural robustness, and durable sodium‐storage performance even under bending/folding. To develop a green, sustainable, and high‐performance anode for sodium‐ion batteries (SIBs), flexible biomass‐based carbon ...

Synergistic Design of Composite Ionogels With Enhanced Thermoelectric Properties, Mechanical Stretchability, and Sustainable Recyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
While flexible TE devices hold promise for converting low‐grade waste heat (e.g., from human skin or electronics) into usable electricity, existing materials suffer from three major limitations: 1) poor mechanical stretchability (failing to match human skin's elongation, ~20–30%), limiting wearability; 2) tradeoffs between thermoelectric efficiency (e ...
