Heptazine‐Assisted Multi‐Resonance TADF Emitters With Fast Reverse Intersystem Crossing for Efficient Solution‐Processed OLEDs

open access: yesAdvanced Materials, EarlyView.
Heptazine‐assisted MR‐TADF emitters enable narrowband yellow emission with high efficiency at high luminance in solution‐processed OLEDs. In doped films, HAP‐3CzBN achieves a record‐fast kRISC of 1.19 × 106 s−1. The optimized HAP‐3CzBN devices deliver 15.5% EQEmax with negligible roll‐off at 1000 cd m−2, 11.2% at 10,000 cd m−2, and a benchmark 20.3 ...

Hexane Air Combustion

open access: yes, 2010
Hot surface ignition and subsequent flame propagation of premixed n-hexane air mixtures are shown in this fluid dynamics video. High speed schlieren photography revealed 3 distinct behaviors of ignition and propagation as a function of mixture composition and initial pressure.

Stable P‐Type PbS Quantum Dot Ink for all‐Blade‐Coated Short‐Wavelength Infrared Photodiodes

open access: yesAdvanced Materials, EarlyView.
Stabilization of p‐type PbS quantum dot ink is achieved through hydrogen bonding between fluorinated alcohols solvent and the MP ligand, allowing a six‐day shelf‐life. The solvent does not compromise pre‐deposited layers, enabling fully blade‐coated photodiodes in both n–p and p–n architectures, with enhanced detectivity and bandwidth compared to layer‐

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

open access: yesAdvanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Liquids as Reinforcements for Anisotropic and Tough Soft Matter Composites

open access: yesAdvanced Materials, EarlyView.
Liquid metal droplets are shaped and oriented within soft elastomers to create all‐soft matter composites with programmable mechanical anisotropy. These liquid inclusions act as fiber‐like reinforcements, enabling directional stiffness, enhanced toughness, and controlled crack steering under extreme deformation, offering new routes to resilient soft ...
