Magnetic Field‐Driven Catalysis: Revealing Enhanced Oxygen Reactions in Li‐O2 Batteries Using Tailored Magnetic Nanocatalysts

open access: yesAdvanced Science, EarlyView.
A series of Mn‐Co‐Fe oxides with different saturated magnetization (Ms) are prepared to evaluate the enhancement catalytic properties of magnetic catalysts on Li‐O2 batteries (LOBs). A deep understanding of the intricate relationship between the magnetism of electrocatalysts and the corresponding performance of LOBs under the influence of magnetic ...

Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

open access: yesChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic

Novel Calibration Strategy for Kalman Filter‐Based Measurement Fusion Operation to Enhance Aging Monitoring

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT This study introduces a novel calibration strategy for the linear Kalman filter (LKF) fusion application in condition monitoring, specifically utilizing accelerated aging data. Unlike the existing literature that often focuses on complex nonlinear Kalman filter variants, this research delves into the calibration of LKF.

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

open access: yesSmall, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction

open access: yesSmall, EarlyView.
Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.

Estimating Solar Wind Charge Exchange Generated Soft X‐Rays in the Jovian Magnetosheath

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Solar Wind Charge eXchange (SWCX) generated soft x‐rays are used extensively to study the interfaces between charged and neutral particles throughout the solar system. This paper outlines the development of a model of Jupiter's magnetosheath using magnetohydrodynamic derived boundary equations and a combination of in situ Juno measurements and

DENSITY-MAGNETIC FIELD CORRELATION IN MAGNETOHYDRODYNAMIC TURBULENCE DRIVEN BY DIFFERENT DRIVING SCHEMES WITH DIFFERENT CORRELATION TIMES

open access: yesThe Astrophysical Journal, 2016
ABSTRACT Turbulent motions naturally produce density and magnetic-field fluctuations. Correlation between the two fluctuations is important for interpretation of observations, such as observations of the rotation measure (RM). In this paper, we study the effect of driving schemes on the density-magnetic-field correlation.

Global Evolution, Energetics, and Origins of Auroral Streamers

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract An auroral streamer—a usually meridionally aligned, arc‐like feature that extend across the auroral oval. We performed a high‐resolution global magnetohydrodynamic simulation to characterize the evolution of streamers and their coupling to magnetotail drivers. The results show that streamers, which are a consequence of magnetotail flow bursts,
