GNSS Zenith Wet Delay as a Boundary Layer Diagnostic: Regime‐Dependent Turbulence Signatures From Large Eddy Simulation and Observations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide continuous measurements of zenith wet delay (ZWD), reflecting column‐integrated atmospheric water vapor. While the slowly varying ZWD is routinely assimilated in numerical weather prediction, the rapid fluctuations on timescales of seconds to minutes that arise from boundary‐layer turbulence ...

High‐Index, Low‐Loss Optical Material Platforms for Ultra‐Broadband Ultraviolet‐to‐Visible Achromatic Metalenses

open access: yesAdvanced Functional Materials, Volume 36, Issue 49, 18 June 2026.
An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, Volume 38, Issue 36, 26 June 2026.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Thermal Analysis of Phase Change Material Based Energy Storage Module With Triply Periodic Minimal Surfaces

open access: yesEnergy Storage, Volume 8, Issue 4, June 2026.
ABSTRACT The thermal performance of two triply periodic minimal surface (TPMS) thermal Energy Storage modules, Diamond and Primitive, was investigated using computational fluid dynamics. The melting and solidification behaviors, as well as the charging and discharging characteristics, of the TPMS Energy Storage units were studied for various flow rates.
