Magneto‐Electrocatalysis: A Multiscale Perspective on Designing High‐Efficiency Electrocatalysts for Clean Energy

Battery Energy, Volume 5, Issue 4, July 2026.
This review presents a multiscale framework for magnetic field‐assisted electrocatalyst synthesis. By synergizing quantum‐scale spin polarization, atomic‐scale force dynamics, and mesoscopic directed assembly, this strategy overcomes conventional design bottlenecks to construct highly efficient, magnetically responsive electrocatalysts for clean energy.

Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

Droplet, Volume 5, Issue 3, July 2026.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...

Unsteady MHD Heat Transfer of a Casson–Williamson Ternary Hybrid Nanofluid Over a Biaxially Stretching/Shrinking Sheet With Cattaneo–Christov Heat Flux and Multi‐Mode Thermal Radiation

Engineering Reports, Volume 8, Issue 7, July 2026.
A numerical study of Casson–Williamson ternary hybrid nanofluid flow reveals that magnetic effects enhance transverse velocity while suppressing axial components, and increased thermal relaxation reduces heat transfer rates under multiple radiation models, highlighting improved control of thermal performance in advanced engineering and electronics ...

Exploring Selection Biases in Fast Radio Burst Dispersion–Galaxy Cross-correlations with Magnetohydrodynamical Simulations

The Astrophysical Journal
The dispersion measures (DMs) of fast radio bursts (FRBs) can be used as powerful probes of the distribution of extragalactic plasma. With a large enough sample, the free-electron–galaxy power spectrum P _eg can be measured by cross-correlating FRB DMs ...

On the Non‐Dimensionalization and Mathematical Equivalence of MHD Nanofluid Jeffery–Hamel Flow

Engineering Reports, Volume 8, Issue 7, July 2026.
This study corrects inconsistencies in the governing equation and Hartmann number used in MHD nanofluid Jeffery–Hamel flow models. The corrected nanofluid formulation is shown to be equivalent to the classical MHD Jeffery–Hamel equation through appropriate parameter scaling.

Physical Constraint Preserving Higher-order Finite Volume Schemes for Divergence-free Astrophysical MHD and RMHD

The Astrophysical Journal
Higher-order finite volume schemes for magnetohydrodynamics (MHD) and relativistic magnetohydrodynamics (RMHD) are very valuable because they allow us to carry out astrophysical simulations with very high accuracy.
