Study of Arc Interruption Characteristics under Rated Current in Low Voltage Circuit Breakers
Energies, 2023 The breaking capacity of rated current is one of the important indexes to evaluate the performance of circuit breakers, which is usually measured experimentally and cannot be analyzed in terms of the arcing characteristics of the opening process ...

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

A semi-empirical approach to simulating the Dst index in global MHD models of Earth’s magnetosphere
Earth and Planetary PhysicsThe Dst index has been commonly used to measure the geomagnetic effectiveness of magnetic storm events for several decades. Based on Burton’s empirical Dst model and the global magneto-hydrodynamic (MHD) simulation of Earth’s magnetosphere, here we ...
