Femtosecond Laser Breaks the Lattice Symmetry and Induces Broadband Second Harmonic Generation in 3D Halide Perovskites

open access: yesLaser &Photonics Reviews, EarlyView.
3D halide perovskites have shown no second harmonic generation (SHG) due to the centrosymmetric nature. The femtosecond (fs) laser ablation breaks their inversion symmetry and formed microstructures of AmPbX3‐n, (0

Cloaked Quasi Bound States in the Continuum in Semiconductor Metasurfaces with Out‐of‐Plane Symmetry Breaking

open access: yesLaser &Photonics Reviews, EarlyView.
The impact of out‐of‐plane symmetry breaking in semiconductor metasurfaces on bound states in the continuum (BICs) with vertical dipole‐like character is theoretically investigated. By tilting/inclining the meta‐atoms–thus effectively rotating the dipolar resonances–a so‐called cloaked quasi‐BIC is excited at a specific angle of incidence ...

Tailoring Flatband Dispersion in Bilayer Moiré Photonic Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
 The photonic dispersion in 1D moiré structures formed by stacking two photonic crystal slabs with slightly different periods is experimentally investigated. By precisely adjusting the filling factor of the photonic crystals, the evolution of moiré minibands into flatbands is experimentally and numerically demonstrated. This result provides a practical

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Interplay Between Spin‐Triplet Pairing and Ferromagnetism in Uranium Ditelluride

open access: yesNano Select, EarlyView.
This study investigates how spin triplet superconductivity and ferromagnetism interact in uranium ditelluride (UTe2). It shows that magnetic fluctuations strongly influence the superconducting behavior. The results suggest that ferromagnetic tendencies can contribute to the stabilization of spin triplet pairing. These findings provide new insights into

Recent Advances in Porphyrin‐Based Magnetic Nanocomposites: Preparation, Characterization, and Catalytic Application in the Epoxidation of Olefins

open access: yesNano Select, EarlyView.
This article reviews the recent advances in the strategies of preparation, characterizations, catalytic efficiency, and plausible mechanisms of metalloporphyrin‐based magnetic nanocatalysts focused on the oxidation of olefins during 2013–2024. ABSTRACT Catalytic oxidation of olefins is a vital class of reaction that has drawn huge interest in both ...
