High‐Efficiency Deep Blue Single‐Gaussian Europium(II) Emitters and Their Emitter‐Host Interactions
Crown‐ether ligands and carborate anions enable vacuum‐processable Eu(II) emitters with efficient single‐Gaussian deep‐blue luminescence. Combined photophysical and computational analyses reveal that excited‐electron confinement and steric shielding of the europium center jointly govern compatibility with OLED host materials, establishing molecular ...

Nanocrystals of Eu-doped GaN powders are produced via pyrolysis of a viscous compound made from europium and gallium nitrates. Furthermore, carbohydrazide is used as a fuel and toluene as a solvent; subsequently, a crucial nitridation process is carried ...

Cortisol Dynamics at High Temporal Resolution For Wearable Biosensor Research
High‐frequency cortisol profiling reveals that endocrine responses depend strongly on both stressor type and the individual. Circadian sampling shows a consistent morning‐to‐evening decline, while cold exposure elicits delayed rises and exercise and cognitive challenges produce divergent trajectories.

The inclusion of the effects of hyperfine splitting can significantly lower the abundance estimate of Eu from singly ionized lines which lie on the flat portion of the curve of growth. In the 21 cool Ap stars studied by Adelman and the five Am stars studied by Smith, the Eu abundance was reduced by 0.4 dex on the average.

The graphical abstract revels the facile synthesis of Eu3+‐MoO3 nanoparticle was by combustion method using Neem leaf material as a fuel. The prepared nanomaterials were well characterized by various spectral techniques. Introducing Eu into the host lattice modifies its electronic structure for improving the power conversion efficiency of hetero ...

Eu‐containing hydroxyapatite nanostructures are synthesized by a microwave‐assisted hydrothermal route using glutamic acid. Eu addition preserves the hexagonal apatite phase while progressively modifying fiber morphology and generating characteristic red emission from low‐symmetry Eu3+ environments.

The here presented compounds Rb3Ln[AsS4]2 with Ln = Gd–Ho represent an extension of the nonisotypic Rb3Ln[AsS4]2 series (Ln = La–Nd, Sm, Gd–Ho). The crystal structures of all representatives of this series contain one‐dimensional chains separated by Rb+ cations.

Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.
