Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Oxygen Vacancy‐Rich S‐Scheme Heterojunction Photocatalyst With Enhanced Interfacial Charge Transfer for Round‐the‐Clock Formaldehyde Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work addresses the critical challenges of severe charge recombination and the dependence on constant light illumination in photocatalysis. We propose a strategy centered on an oxygen vacancy‐rich S‐scheme heterojunction, which enables precise regulation of charge carrier behavior and achieves long‐lasting photocatalytic performance.

Electroluminescence afterglow from indium tin oxide/Si-rich SiO2/p-Si structure

, 2006
Indium tin oxide/Si-rich SiO2/p-Si structured devices are fabricated to study the electroluminescence (EL) of the Si-rich SiO2 (SRO) material. The obvious peaks at similar to 1050nm and similar to 1260nm in the EL are ascribed to localized state ...

On the External Inverse Compton Scattering off the Prompt Emission in GRB 221009A

The Astrophysical Journal
The temporal evolution of the TeV emission of GRB 221009A displays a smooth transition from an initial rapid rise to a slower rise and eventually a decay phase. The smooth light curve suggests an afterglow origin of the TeV emission. The temporal overlap

Imaging-guided companion diagnostics in radiotherapy by monitoring APE1 activity with afterglow and MRI imaging

Nature Communications
Companion diagnostics using biomarkers have gained prominence in guiding radiotherapy. However, biopsy-based techniques fail to account for real-time variations in target response and tumor heterogeneity.

Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

Fire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Afterglow ice formed by phosphorescent luminophore-protein conjugates and complexes in aqueous solution at freezing temperature

Nature Communications
Unlike the widely reported fluorophore-biomacromolecule systems in nucleic acid testing and immunoassay, organic afterglow luminophore-biomacromolecule conjugates and complexes remain rarely explored.
