Orbital Coupling and Electron Delocalization Engineered at Fe/V Heterointerfaces for Enhanced Cathode Performance in Sodium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In the NFPF–NVPF heterostructure, the interfacial FeV 3d‐orbital coupling drives the upshifting of the d‐orbital and facilitates electron delocalization. This dual‐effect mechanism significantly expands the spatial distribution of electrons and narrows the bandgap, thereby constructing synergistic electron‐ion transport channels to achieve excellent ...

Varieties of Local Implementation for Net Zero in China: Evidence From Three Cities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Since China updated its nationally determined contributions in 2021, achieving carbon peaking before 2030 and carbon neutrality before 2060—the so‐called “dual carbon” goals—has become the new guiding principle of China's climate governance. However, few studies have examined the implementation of China's dual carbon goals, particularly the ...

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks

open access: yesEnergy Science &Engineering, EarlyView.
This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell

Programmable luminescent platform based on carbon quantum dots enables wavelength‐multiplexed optical data storage and encryption

open access: yesFlexMat, EarlyView.
A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

open access: yesFlexMat, EarlyView.
By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...
