Electronegativity‐Guided Site Differentiation in High‐Entropy Alloy for pH‐Universal Hydrogen Evolution Reactions

open access: yesAngewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Electronegativity‐guided site differentiation is realized in a CoNiCuMoW high‐entropy alloy, where Co/Ni sites optimize hydrogen binding strength, Mo/W sites promote water dissociation, and Cu‐associated sites contribute to balanced hydrogen adsorption.

Quantifying Nighttime Gravity Wave‐Driven Mesosphere‐Ionosphere Coupling Over CONUS Using NASA AWE Radiance and GNSS TEC Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We present the first coordinated study of nighttime mesosphere‐ionosphere coupling over the continental United States (CONUS) from January through November 2024 using NASA Atmospheric Waves Experiment (AWE) airglow measurements near 87 km and GNSS Total Electron Content observations near 300 km.

Pathway Complexity Defines the Shape of Nucleic Acid‐Loaded Polyion Complex Micelles: Spheroids vs. Hexagonal Disks

open access: yesAngewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Same building blocks, different destinies. Pathway complexity directs nucleic acid–loaded polyion complex micelles along distinct assembly trajectories, resulting in either hexagonally shaped or spheroidal nanoparticles with distinct internal structuring.

Surface‐Constrained Reconstruction of Spatiotemporal Turbulence Dissipation in the Convective Boundary Layer Using Physics‐Guided Machine Learning

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Turbulence dissipation rate (EDR) governs the conversion of turbulent kinetic energy to heat and thereby controls vertical mixing, transport, and energy exchange in the convective boundary layer (CBL). The spatiotemporal structure of EDR remains poorly constrained, as observations are limited to point measurements or sparse vertical profiles ...

Interferometric Near‐Field Scanning Optical Microscopy via Phase Conjugation of a Multimode Fiber Probe

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A multimode fiber probe collects far more of the near field than a single‐mode one, but scrambles the phase into speckle. Phase conjugation on a spatial light modulator restores the wavefront, concentrating the signal up to 165‐fold at a single detector pixel and recovering the full phase of propagating surface plasmon polaritons where conventional ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
