Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Biomimetic Ion Channel Design for Simultaneous Lithium‐Ion Flux Regulation and Interfacial Stabilization in Lithium Metal Batteries

open access: yesSmall, EarlyView.
Inspired by biological cell membranes, BCE‐encapsulated MOFs create bionic Li+ transport channels. These channels homogenize Li+ flux via Li+‐crown ether ion‐dipole interactions and manipulate solvation structures to form inorganic‐rich SEI layers.
