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

open access: yesAdvanced 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 ...

Local support against gravity in magneto-turbulent fluids

open access: yes, 2013
Comparisons of the integrated thermal pressure support of gas against its gravitational potential energy lead to critical mass scales for gravitational instability such as the Jeans and the Bonnor-Ebert masses, which play an important role in analysis of

Unraveling the Trigger Mechanism of Explosive Reconnection in Partially Ionized Solar Plasma

open access: yesThe Astrophysical Journal
Plasmoid instability usually accounts for the onset of fast reconnection events observed in astrophysical plasmas. However, the measured reconnection rate from observations can be one order of magnitude higher than that derived from magnetohydrodynamic ...

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

open access: yesChemElectroChem, 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.

Magnetorotational instability in decretion disks of critically rotating stars and the outer structure of Be and Be/X-ray disks

open access: yes, 2014
Evolutionary models of fast-rotating stars show that the stellar rotational velocity may approach the critical speed. Critically rotating stars cannot spin up more, therefore they lose their excess angular momentum through an equatorial outflowing disk ...

Recent advances in boosting interfacial bubble dynamics with external fields

open access: yesDroplet, 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 ...

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

open access: yesThe 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 ...

Determining the optimal locations for shock acceleration in magnetohydrodynamical jets

open access: yes, 2010
Observations of relativistic jets from black holes systems suggest that particle acceleration often occurs at fixed locations within the flow. These sites could be associated with critical points that allow the formation of standing shock regions, such ...

Explosive Nucleosynthesis in Magnetohydrodynamical Jets from Collapsars II. Heavy-Element Nucleosynthesis of s, r, p-Processes

open access: yes, 2012
We investigate the nucleosynthesis in a massive star of 70 M_solar with solar metallicity in the main sequence stage. The helium core mass after hydrogen burning corresponds to 32 M_solar.

Magnetohydrodynamic Simulation of Solar Supergranulation

open access: yes, 2006
Three-dimensional magnetohydrodynamical large eddy simulations of solar surface convection using realistic model physics is conducted. The effects of magnetic fields on thermal structure of convective motions into radiative layers, the range of convection cell sizes and penetration depths of convection is investigated. We simulate a some portion of the
