Detection of Hybrid Optical Anapoles in Dielectric Microspheres

Advanced Optical Materials, EarlyView.
In this work, hybrid optical anapoles are detected in dielectric microspehers using dual detection optical spectroscopy. The results show that the excitation of TiO2 microspheres under tightly focused Gaussian Beam illumination leads to the appearence of scattering minima in both the forward and backward directions within specific wavelength ranges ...

Surface Oxidation of 2D γ‐Indium Sulfide Nanoplatelets and Its Impact on Photoluminescence

Advanced Photonics Research, EarlyView.
Photoluminescence of defective 2D γ‐In2S3 can be modulated after exposure to air or oxygen‐containing ligands. Cryogenic photoluminescence measurements reveal that a new acceptor level is introduced upon oxidation, modulating the relative intensity of the emission bands.

Proving Optical Anisotropy and Polarization Effects in β‐Ga2O3$\left(\text{Ga}\right)_{2} \left(\text{O}\right)_{3}$ Nanomembranes via X‐Ray Excited Optical Luminescence

Advanced Photonics Research, EarlyView.
In this study, the pronounced anisotropy in the optical properties of β‐Ga2O3 nanomembranes has been analized under a synchrotron nanoprobe. We have investigated the site‐specific contributions of distint Ga ions to the emission bands by combining polarization‐dependent X‐ray absorption near‐edge structure and X‐ray excited luminescence.

Effect of Co and Mn Doping on the Electronic and Magnetic Properties of XC₂ (X = Hf, Zr) MXene Monolayers: A First‐Principles Study

Advanced Theory and Simulations, EarlyView.
The electronic and magnetic properties of Co and Mn doped Hf₂C and Zr₂C MXene monolayers are investigated using first principles DFT+U calculations. Doping significantly modifies both the electronic structure and magnetic behavior, with bandgap opening that may be suitable for infrared applications.

Engineering PdAu/CeO2 Alloy/Oxide Interfaces for Selective Methane‐to‐Methanol Conversion with Water

Angewandte Chemie, EarlyView.
Selective methane‐to‐methanol conversion at 500 K over Pd0.3Au0.7/CeO2. The synergistic interaction between alloyed Pd–Au sites and the CeO2 support enhances catalytic performance, enabling highly selective methane‐to‐methanol under mild conditions. The reaction of CH4 with H2O produces CH3OH and H2, achieving ∼80% selectivity under mild conditions ...
