Unusual Thermal Transport in Few‐Layer Van der Waals Antiferromagnet CrOCl

Advanced Science, EarlyView.
Thermal transport serves as an ultra‐sensitive probe for detecting the magnetic order in 2D materials. Using the suspended thermal bridge method enhanced by Wheatstone bridges, it is, for the first time, observed anomalous critical behavior in few‐layer CrOCl near its Néel temperature.

Mechanistic Insights into the Structural Evolution of ZIF‐67 via Electrospinning Strategy Toward High Electromagnetic Wave Absorption Performance of ZIF‐67‐Derived Carbon Nanofibers

Advanced Science, EarlyView.
With 5G and AI robotics rising, electromagnetic radiation risks signal security and health. This work investigates the electromagnetic wave absorption of Co/CNF composites via in situ and ex situ electrospinning strategies. The in situ synthesized sample exhibits superior absorption properties due to enhanced structural uniformity, improved Co ...

Phosphorus Vacancy‐Induced Built‐In Electric Field for Electromagnetic Properties Modulation

Advanced Science, EarlyView.
The advantages of defect‐induced polarization resulting from group VA anion vacancies, particularly phosphorus vacancies (VP) are analyzed in comparison to the anion vacancies of other elements. P atoms possess both plentiful high‐energy unpaired valence electrons in 3p orbitals and moderate nonmetallicity, thus the selection of VP for regulating EM ...

Proton Acceleration with Relativistic Electromagnetic Shock

Advanced Science, EarlyView.
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Multi‐Dimensional Multiplexed Metasurface for Multifunctional Near‐Field Modulation by Physics‐Driven Intelligent Design

Advanced Science, EarlyView.
The expansive design space of advanced metasurfaces, particularly those with multiple degrees of freedom (MDOF), renders traditional design methods less effective. A physics‐driven intelligent design is proposed for MDOF metasurfaces, which integrates physical knowledge into neural networks, enhancing interpretability and computational efficiency. This
