Daytime Ionospheric Density Enhancement Driven by Poleward Neutral Wind Shear Associated With Gravity Waves During the November 2025 Geomagnetic Storm

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The threefold daytime electron density increases, along with strong poleward meridional winds exceeding 200 m/s were captured by Sanya Incoherent Scatter Radar (SYISR) during the geomagnetic storm of 12 November 2025. The great ionospheric enhancements were extending to mid‐latitudes over 40° observed by total electron content (TEC) from ...

Inverse Design for Robust Inference in Integrated Computational Spectrometry

open access: yesNanophotonics, Volume 15, Issue 7, 13 April 2026.
This work demonstrates that integrated computational spectrometers can be inverse‐designed to substantially improve noise tolerance without relying on training data or specific inference algorithms, offering an alternative to conventional end‐to‐end co‐design strategies.

Feasibility Study for Dual Phase Free Breathing 3D bSSFP MRA With Preserved Eddy‐Current Tolerance With Adaptive k‐Space Lengths (PETAL) Acquisition

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2078-2091, April 2026.
ABSTRACT Purpose To demonstrate the feasibility of a novel dual‐phase self‐navigated, free‐breathing balanced steady‐state free‐precession whole‐heart MRA acquisition for aortic annulus size measurement using a Cartesian trajectory that mitigates eddy‐current artifacts by minimizing k‐space jumps between consecutive readouts with predictable scan times.

Superimposed Sacrificial Texturing to Enhance the Optical Performance in Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 465-481, April 2026.
Sacrificial texturing method using controlled etching of undoped zinc oxide and indium‐doped tin oxide generates microscale and nanoscale textures on glass. Roughness on two different scales is superimposed to create a new texture capable of broad‐spectrum scattering, which is utilised in thin‐film silicon solar cells to enhance optical performance ...

Polarons in Heterogeneous Photo(electro)Catalysts

open access: yesAngewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Polarons are defined as quasiparticles consisting of electrons/holes covered by a cloud of virtual phonons, which are beneficial/detrimental to the electronic properties of materials. This minireview provides a conceptual overview of how small polaron formation influences the photon absorption, charge transport and separation, and surface reactivity in
