Potentiostatic Electrodeposition of Binder‐Free Ni–W Electrodes for Coupled Energy‐Saving Hydrogen Production and Urea Remediation

EcoMat, Volume 8, Issue 6, June 2026.
A binder‐free Ni–W nanostructured electrode is fabricated via controlled potentiostatic electrodeposition on carbon paper that aligns with circular economy principles. The electrode enables energy‐efficient hydrogen production coupled with urea remediation, achieving 100 mA cm−2 at 1.77 V and degrading 47% of urea over 30 h.

High‐Resolution Microlens‐Assisted Tunable n‐Type Optical Doping in Monolayer MoS2

Small, Volume 22, Issue 33, 12 June 2026.
The laser‐assisted microlens array processing (LAMP) technique enables sub‐diffraction, localized n‐type optical doping of monolayer MoS2 by utilizing self‐assembled microspheres as microlenses. Controlled sulfur vacancy formation under low‐power laser irradiation allows precise tuning of the carrier concentration.

High‐Barrier Amorphous Al2O3 Film Deposited via Magnetic Field‐Confined for Ultrastable Hygroscopic Scintillators

SmartMat, Volume 7, Issue 3, June 2026.
The moisture‐induced degradation of hygroscopic scintillators limits their performance and lifespan in radiation detection. A 100 nm amorphous Al2O3 film, deposited at room temperature via FCVA with pulsed magnetic field confinement, offers high optical transmittance and ultralow moisture permeability.

First Observation of Sawtooth‐Like Undulations in Afternoon Detached Auroral Arcs Modulated by Surface Waves at the Plasmaspheric Plume Boundary

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.

Contemporaneous Appearances of Auroral Spiral and Transpolar Arc: Polar UVI Observations and Global MHD Simulations

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract A local vortex‐structured aurora and a large‐scale transpolar arc (TPA) were contemporaneously observed by the Polar ultraviolet imager (UVI) during the late recovery phase of a substorm, and the interplanetary magnetic field (IMF) BY and BZ were negative and negative‐to‐positive. The TPA grew along the dawnside auroral oval from the nightside

On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]

, 2015
PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).

Influence of Solar Sails on Magnetic Field Measurements in Space Plasmas

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Solar sail technology is ready to be deployed in a satellite mission carrying a science‐grade magnetometer. In preparation for such a mission, it is essential to characterize the interactions between the sail and the ambient plasma that could affect the magnetometer readings.

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,

Ionosphere‐Thermosphere Responses to the March 2023 Geomagnetic Storm Using Observations and TIEGCM Simulations Driven by Data Assimilated Aurora and Electric Fields

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We investigate Ionosphere‐Thermosphere (IT) responses to the March 2023 geomagnetic storm using GOLD and PFISR observations, along with TIEGCM simulations driven by data‐assimilated aurora and electric fields. A Lattice Kriging approach is implemented to assimilate auroral electron flux and characteristic energy from ground‐based (THEMIS/ASIs)

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
