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

open access: yesEcoMat, 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

open access: yesSmall, 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

open access: yesSmartMat, 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

open access: yesAGU 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

open access: yesEarth 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
