Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

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 ...

Unprecedented Wall‐Atomically Thick Bi5O7Br Nanotubes Embedding Abundant Bi Nanodots Boosting Efficiently Photothermal Coupling Catalytic CO2 Conversion

open access: yesEcoEnergy, EarlyView.
Atomically thin Bi5O7Br nanotubes embedded with abundant Bi nanodots were constructed as an efficient photothermal catalyst for CO2 conversion. The localized surface plasmon resonance and photothermal effect of Bi nanodots synergistically enhance light harvesting, charge utilization, and reaction kinetics, resulting in significantly improved CO2 to CO ...
