Internal Magnetic Fields Enhance Capacity Retention in Aqueous Zinc‐Organic Batteries With Quinone Cathodes

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
Internal magnetic fields incorporated in aqueous zinc‐ion batteries behind both the anode and cathode prevent dendrite growth on the anode surface and enhance active material retention at the cathode during battery operation. The development of alternatives to lithium‐ion batteries (LIBs) is critical to address concerns related to resource availability,

High-beta axisymmetric equilibria with flow in reduced single-fluid and two-fluid models [PDF]

, 2008
Reduced single-fluid and two-fluid equations for axisymmetric toroidal equilibria of high-beta plasmas with flow are derived by using asymptotic expansions in terms of the inverse aspect ratio. Two different orderings for the flow velocity, comparable to

Thermal and Bioconvective Modeling and Analysis of Unsteady Cu‐Water Nanofluid Flow through Porous Media with Gyrotactic Microorganisms

Engineering Reports, Volume 8, Issue 9, September 2026.
The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

A Hybrid FEM–ML Framework for Magnetohydrodynamic Combined Convective Heat Transfer Performance of Hybrid Nanofluid Flow in a Horizontal Wavy Channel

Engineering Reports, Volume 8, Issue 9, September 2026.
The maximum heat transfer rate is observed at Ri = 10, Ha = 0, and ϕ = 0.06 under the default parameter settings for different boundary conditions. The proposed ANN model demonstrates good predictive and classification accuracy in estimating the average Nusselt number for both cases. ABSTRACT This computational study introduces a novel hybrid framework

Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders

Frontiers in Neurology, 2014
We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD) Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best ...

Thermal Behavior of Radiative Darcy–Forchheimer Nanofluid Flow With Heat Source/Sink Effects

Engineering Reports, Volume 8, Issue 9, September 2026.
Radiative Darcy–Forchheimer nanofluid flow in a porous medium is numerically analyzed with heat source/sink effects. Radiation enhances heat transfer and boundary layer thickness, while increasing Forchheimer resistance suppresses velocity, providing insights for optimizing thermal management in high‐temperature porous systems.

A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.
