High‐Order Janus Bound States in the Continuum Assisted by Unidirectional Guided Resonances

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
A high‐order Janus bound state in the continuum, featuring a q = −3 vortex in the upward radiation channel and a q = +1 vortex in the downward channel, is realized in truncated‐cone photonic crystal slabs by merging unidirectional guided resonances with a symmetry‐protected BIC, enabling direction‐dependent control of topological light emission ...

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.

Sustainable Ball Milling‐Assisted Synthesis of Bread Waste‐Derived Highly Porous Carbons for Adsorption‐Based Applications

open access: yesChemPhysChem, Volume 27, Issue 13, 14 July 2026.
A simple strategy is proposed to convert food waste such as dry bread into highly porous carbons that can be used for catalysis and adsorption‐related applications. Namely, a fast ball milling of dry bread and a mild activation agent, followed by carbonization at 800°C, is used to obtain porous carbons with surface areas up to 2400 m2/g.

Overcoming Computational Bottlenecks in Quantum Hydrodynamics: A Volume‐Based Integral Formalism for Spherical Nanoparticles

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...

Wavelength and Polarization Multiplexed Nonlocal Metasurface for Quantitative Phase Microscopy

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
A nonlocal metasurface with wavelength and polarization multiplexed optical transfer functions is demonstrated for performing quantitative phase imaging. The metasurface uses the angular dispersion of optical routing guided mode resonances to extract phase gradient information along different directions for phase retrieval. ABSTRACT Imaging transparent
