Thermal Conduction in Laser‐Driven Tin Plasmas and the Sensitivity of Plasma Properties to the Flux Limiter

Contributions to Plasma Physics, EarlyView.
ABSTRACT We study the role of thermal conduction in laser‐produced tin plasma sources of extreme ultraviolet (EUV) light using radiation‐hydrodynamic simulations. Adopting the flux‐limited Spitzer–Härm approach, we investigate the sensitivity of the electron temperature, electron density, net in‐band emissivity, and conversion efficiency to the choice ...

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

Deep 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 ...

Bioinspired Flexible and Stretchable Coil Structure from Ti3C2Tx MXene/AgNPs‐Functionalized Piezoelectric Nanofibers for Enhanced Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ti3C2Tx MXene and Ag nanoparticles are embedded into piezoelectric nanofibers to form a stretchable, self‐powered coil that converts mechanical deformation into electrical energy. The device enables controllable power output during stretching and release while maintaining a compact and lightweight architecture, making it suitable for miniaturized ...

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...
