Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere.

Non-ideal magnetohydrodynamics on a moving mesh

, 2018
In certain astrophysical systems the commonly employed ideal magnetohydrodynamics (MHD) approximation breaks down. Here, we introduce novel explicit and implicit numerical schemes of ohmic resistivity terms in the moving-mesh code AREPO. We include these

Mars' Ionospheric Response to the Onset and Early Phase of 20 May 2024 Solar Flare

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar extreme ultraviolet (EUV, 10–100 nm) and X‐ray (<10 nm) photons are the primary ionization source for the dayside Mars ionosphere. Their fluxes, especially at short wavelengths, increase significantly during solar flares. Among the series of solar flares and solar storms encountered by Earth and Mars in May 2024, one of the strongest ...

Extended Kelvin theorem in relativistic magnetohydrodynamics [PDF]

, 2000
We prove the existence of a generalization of Kelvin's circulation theorem in general relativity which is applicable to perfect isentropic magnetohydrodynamic flow. The argument is based on a new version of the Lagrangian for perfect magnetohydrodynamics.

Science‐Towards‐Technology Breakthrough in CO2 Electroreduction: Multiphysics, Multiscale, and Artificial Intelligence Insights

Advanced Materials, Volume 38, Issue 22, 17 April 2026.
Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Notes on the exact solutions and singularities of an X-point collapse in Hall magnetohydrodynamics

, 2018
A recent paper by A.~Z.~Janda [J.~Math.~Phys.~{\bf 59}, 061509 (2018)] presented a partial solution of the equations of dissipationless Hall magnetohydrodynamics (MHD) in terms of the Weierstrass elliptic function. Unfortunately, an error crept up in the

Unraveling Oxygen Evolution Reaction Enhancement Mechanisms: From Internal to External Fields of Electrolyzers

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
This review systematically examines strategies for enhancing alkaline water electrolysis through internal catalyst engineering and external field assistance (light, magnetic fields). It proposes an integrated internal‐external field framework, elucidating synergistic mechanisms at electronic, mass transport, and system stability levels.

Smoothed Particle Magnetohydrodynamics III. Multidimensional tests and the div B = 0 constraint

, 2005
In two previous papers (Price & Monaghan 2004a,b) (papers I,II) we have described an algorithm for solving the equations of Magnetohydrodynamics (MHD) using the Smoothed Particle Hydrodynamics (SPH) method.

Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, Volume 5, Issue 2, April 2026.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

A simplified mathematical theory of MHD power generators

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
We present a simplified version of the Faraday magnetohydrodynamics (MHD) generators theory. The effect of the Loretz force against the fluid ow is neglected, whence it follows the uniform ow of the plasma. We use Lazăr Dragoș’s analytic solution for the
