Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2

Advanced Materials, Volume 38, Issue 53, 21 September 2026.
Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

A Compact Three‐Layer VO2‐Integrated Reflective THz Metasurface With Switchable Half‐Wave‐Plate and Quarter‐Wave‐Plate Responses

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
A switchable terahertz polarization conversion metasurface is demonstrated, utilizing the insulator‐to‐metal phase transition to achieve binary functionality within a single device. By toggling between material states, the metasurface provides high‐performance linear‐to‐circular (LTC) conversion in the insulating phase and linear‐to‐linear (LTL) cross ...

Optical Windows for Transcranial Brain Imaging in Living Mice: Skull Thinning, Clearing, and Beyond

Advanced Science, Volume 13, Issue 52, 18 September 2026.
Longitudinal, noninvasive in vivo imaging is crucial for studying brain physiology. Advances in transcranial optical windows and multiphoton microscopy have improved imaging depth, but their performance often deteriorates over time. This work investigated various transcranial window approaches and found that skull regrowth limits image quality.

Dictionary‐based weak‐form training for noise‐robust series hybrid models with multiplicative unknowns

AIChE Journal, Volume 72, Issue 9, September 2026.
ABSTRACT Hybrid modeling combines first‐principles equations with a data‐driven subcomponent. Training for the data‐driven part is sensitive to measurement noise when training targets are constructed using pointwise time derivatives. Beyond differentiation errors, hybrid models involve solving an inverse problem to estimate the data‐driven term, which ...

Gradient‐Based Optimization Modeling of Total Entropy and Heat Transfer in Exothermic Blood Analog Gold Nanoparticle Suspension

Engineering Reports, Volume 8, Issue 9, September 2026.
This study develops a gradient‐based multi‐start Nelder–Mead optimization framework for Casson‐micropolar blood‐analog nanofluid flow with gold nanoparticles in a convectively heated, exothermic microchannel, motivated by photothermal drug delivery. Spectral collocation solves coupled momentum, microrotation, and energy equations, from which entropy ...
