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 ...

Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

EcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...

Radio detection of cosmic rays with the Auger Engineering Radio Array

, 2016
International audienceThe very low statistics of cosmic rays above the knee region make their study possible only through the detection of the extensive air showers (EAS) produced by their interaction with the constituents of the atmosphere.

Boosting CO2 Selective Electroreduction to CH4 With High Efficiency Over Oxygen‐Riched Cu‐CeO2 Catalyst by Constructing Heterointerface Built‐in Electric Field

EcoEnergy, EarlyView.
Defect‐rich Cu‐CeO2 heterojunction generates a strong built‐in electric field, accelerates directional electron transfer from CeO2 to Cu, and enables highly selective and efficient CO2 electroreduction to CH4. ABSTRACT Electrochemical CO2 reduction reaction (CO2RR) to CH4 offers a sustainable route for carbon neutrality, but it is hindered by sluggish ...
