Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,

Revealing the Resonant Physics of Open Photonic Time Crystals

Laser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Advances in Floating Solar Desalination Systems

Water and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.

In Situ SrF2 Crystallization in Transparent Germanate Glass‐Ceramics Driven by Erbium for NIR and MIR Applications

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Transparent oxyfluoride glass‐ceramics combining broad ultraviolet‐to‐mid‐infrared transmission with enhanced rare‐earth luminescence are promising materials for mid‐infrared photonic applications. In this work, erbium‐doped indium‐germanate oxyfluoride glasses exhibiting good glass‐forming ability under conventional melt–quenching conditions ...

Generating Circularly Polarized Light Using Hybrid Near‐Zero and High‐Index Materials

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A flat‐optics approach to manipulating the polarization state of light is proposed using evanescent‐wave interactions in hybrid epsilon‐near‐zero and high‐index materials. The design enables linear‐to‐circular polarization conversion in a wavelength‐scale device design without depending on patterning or bulky optics and operates in both reflection and ...

Design of polychromatic focusing optics for neutron reflectometers: rethinking REFocus optics

Journal of Applied Crystallography, Volume 59, Issue 3, Page 774-782, June 2026.
REFocus optics, employing an elliptical mirror and higher‐order reflections, enable rapid wide‐Q‐range neutron reflectometry at reactor sources, achieving up to 100‐fold faster measurements compared with conventional methods.Neutron reflectometry is a widely used non‐destructive technique for analyzing surface and interfacial structures. In this study,

Terahertz Encryption With a Polarization‐Sensitive Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...
