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 ...

EcoEnergy, EarlyView.This review summarizes a descriptor‐guided framework for linking theoretical calculations, in situ/operando characterization, synthesis regulation, and application screening in functional materials. Emphasis is placed on dynamic structure–property relationships that enable low‐cost material design with enhanced activity, stability, and environmental ...

Ecography, EarlyView.The theory of island biogeography (TIB) remains contentious for microbes, as their immense dispersal potential and microscopic size may decouple diversity from classic isolation/area effects. We explicitly tested TIB scaling rules for soil bacteria and fungi across 20 oceanic islands using a rigorous multi‐scale framework that integrated high ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...

Single and Dual Helical Polarizers for Millimeter-Wave Horn Antennas
IEEE Open Journal of Antennas and PropagationThis paper presents a helical-based polarizer integrated into the aperture of a pyramidal horn antenna, designed to convert linearly polarized radiated fields into either right- or left-handed circular polarization over two distinct bands. The integrated

Self-Filtering Low-Noise Horn Antenna
, 2012 "In this contribution, we propose an innovative horn antenna design capable to filter undesired noise out. The radiator is based on a regular WR-62 horn, having a metallic screen inserted between the feeding waveguide and the flared aperture.
