Carbon and Hydrogen, EarlyView.Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high

Light‐Modulated Exchange Bias in Multiferroic Heterostructures
Electron, EarlyView.In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Does age influence diagnostic outcomes in an adult cohort referred to a first‐seizure clinic?
Epilepsia, EarlyView.Abstract Objective The aging Danish population is associated with increasing morbidity and healthcare utilization. This study examines age‐related differences in resource utilization and diagnostic outcomes between older (65–95 years) and younger adults (18–64 years) evaluated for suspected epilepsy, including clinical management, diagnostic yield, and
