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,

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

Collisional and viscous damping of MHD waves in partially ionized plasmas of the solar atmosphere [PDF]

, 2004
Magnetohydrodynamic (MHD) waves are widely considered as a possible source of heating for various parts of the outer solar atmosphere. Among the main energy dissipation mechanisms which convert the energy of damped MHD waves into thermal energy are ...

Statistical field theory of forced magnetohydrodynamic turbulence

Natural Science Review
We review the results of applying the statistical field-theoretic approach to the problem of fully developed turbulence in nonrelativistic three-dimensional magnetohydrodynamics (MHD), which have been obtained over the past forty years.

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.
