Surface‐Mounted Metal‐Organic Framework for the Adsorption and Sensing of Monoaromatic Pollutants in Water Using Quartz Crystal Microbalance

Advanced Materials Technologies, EarlyView.
A hydrophobic metal‐organic framework (UHMOF‐100) is grown on a quartz crystal microbalance sensor for the first time. The device enables real‐time, selective detection of monoaromatic BTEX pollutants in water, demonstrating a new strategy for creating robust chemical sensors for challenging environmental monitoring applications.

Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors

Advanced Optical Materials, EarlyView.
Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

High‐Tc Superinductors Through Tailored Metamaterial Losses

Advanced Optical Materials, EarlyView.
This work presents a loss‐engineering approach for designing high‐temperature superconducting superinductors using YBCO metamaterials. By analyzing radiative and ohmic losses through coupled‐mode theory, the study reveals that partial ohmic loss supports superinductance in thinner films.

First Tellurite Composite Fiber with NIR‐Driven Green Persistent Luminescence

Advanced Optical Materials, EarlyView.
The first composite fiber based on SrAl2O4:Eu2+, Dy3+ PeL phosphors embedded in Yb3+/Tm3+ co‐doped tellurite glass is developed. The fiber exhibits green afterglow driven by 980 nm laser injection, suggesting that the PeL phosphors survive the fabrication process and the blue upconversion from the Yb3+/Tm3+ co‐doped glass matrix is strong enough to ...

Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

Advanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.
