Prediction of Construction Water Inflow of Karst Water-Rich Tunnel Without Drainage Tunnel

open access: yes
AbstractThe construction of infrastructure in China faces substantial challenges due to the complex geological conditions and groundwater in karst areas, particularly in tunnel construction. The construction of the Maoping Port railway tunnel in the Three Gorges Hub area has been accompanied by the emergence of caves and faults.

Active Oscillations of Elastic Membranes Arising from the Coupling with a Catalytic Reaction

open access: yesAdvanced Science, EarlyView.
Coupling an elastic membrane to a catalytic reaction produces active oscillations that self‐sustain for hours: the membrane cyclically inflates and deflates as the reaction spontaneously activates and deactivates, without external power. Energy release is directly embodied in the oscillation dynamics, opening elasto‐chemical strategies for the physical

Mechanisms behind consolidation-induced water release from effective impermeable soil layers and mine water inflow prediction in coal mining

open access: yesMeitian dizhi yu kantan
BackgroundIn the Yushen mining area, coal mining is gradually shifting toward areas with thick soil layers. This leads to continuous water release from the saturated soils above the hydraulically conductive fracture zones, thereby significantly ...

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

open access: yesAdvanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Sea Cucumber‐Inspired Double‐Network Biopolymer Hydrogels for Programmable Soft Machines

open access: yesAdvanced Science, EarlyView.
Inspired by the mutable dermis of sea cucumbers, the collagen‐alginate double‐network elastomeric (CoDE) hydrogel achieves programmable, recoverable, and functional mechanical behavior. The CoDE hydrogel mimics the mutable stiffness of the sea cucumber dermis through a densified collagen cryogel scaffold that is secondarily reinforced by a dissipative,
