Advanced Science, EarlyView.Sulfur atoms are inserted into the multiple‐resonance thermally activated delayed fluorescence framework for developing pure green emitters. The analogous isomers present distinguishing photophysical and electroluminescent properties. The better emitter‐based non‐sensitized device exhibits a maximum external quantum efficiency of 36.4% and a remarkable

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution
Advanced Science, EarlyView.The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...

Angewandte Chemie, EarlyView.A readily accessible, well‐defined iron(II) catalyst that demonstrates high efficiency and versatility in positional and geometrical alkene isomerization is presented. A comprehensive mechanistic study suggests an alkyl mechanism via an isolable iron hydride species and indicates the stereo‐ and rate‐determining β‐hydride elimination step exhibits a ...

Operation of an electron-bombardment ion source using various gases [PDF]
An electron-bombardment ion thruster of the SERT 2 type was operated with xenon, krypton, argon, neon, nitrogen, helium, and carbon dioxide. The discharge performance with xenon, krypton, and argon was similar to that obtained previously with mercury ...
