Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, EarlyView.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Study of Solvent Effect on PVDF‐HFP Gel Polymer Electrolyte Containing Ionic Liquid Pyr1,4TFSI for Lithium Batteries Application

open access: yesMacromolecular Rapid Communications, EarlyView.
The study develops gel polymer electrolytes using PVDF‐HFP copolymer, lithium salt, and an ionic liquid, evaluates how different solvents affect crystallinity, thermal stability, microstructure, and conductivity, observes a crystallinity decrease from 31% to 11%, identifies solvent‐dependent membrane morphologies, and reports the highest conductivity ...

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

open access: yesOikos, EarlyView.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.
