Explosively-driven magnetohydrodynamic (MHD) generator studies [PDF]

Digest of Technical Papers. Tenth IEEE International Pulsed Power Conference, 2002
Plasma jet generators have been designed and tested which used an explosive driver and shocktube with a rectangular cross section that optimize the flow velocity and electrical conductivity. The latest in a series of designs has been tested using a reactive load to diagnose the electrical properties of the MHD generator/electromagnet combination.

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

Flattening of the Density Spectrum in Compressible Hall-MHD Simulations

Atmosphere, 2021
Observations of proton density fluctuations of the solar wind at 1 au have shown the presence of a decade-long transition region of the density spectrum above sub-ion scales, characterized by a flattening of the spectral slope.

Critical balance in magnetohydrodynamic, rotating and stratified turbulence : towards a universal scaling conjecture [PDF]

, 2009
It is proposed that critical balance - a scale-by-scale balance between the linear propagation and nonlinear interaction time scales - can be used as a universal scaling conjecture for determining the spectra of strong turbulence in anisotropic wave ...
