Acetylene Functionalization of Multiple‐Resonant Materials Enabling Strong Two‐Photon Absorption and Delayed Luminescence With Highly Efficient Exciplex‐Sensitized Electroluminescence

Advanced Optical Materials, Volume 14, Issue 34, 11 September 2026.
Multiple‐resonance thermally activated delayed fluorescent (MR‐TADF) material absorbs two near‐infrared 760 nm photons with cross‐section up to 156 GM, emit 26 nm narrowband green light at 491 nm with unity luminescence quantum yield and electroluminescence efficiency up to 25.2% in organic light‐emitting diode.

Enhanced Operational Stability of Carbene‐Metal‐Amide Organic Light‐Emitting Diodes by Reducing Electron Accumulation on the Emitter

Advanced Optical Materials, Volume 14, Issue 34, 11 September 2026.
Carbene‐metal‐amide (CMA) organic LEDs suffer from poor stability despite submicrosecond excited‐state lifetimes. Here, we show that electron accumulation on CMA emitters triggers bond cleavage, while poor electron transport amplifies OLED instability.

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, Volume 3, Issue 3, Page 359-367, September 2026.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Leaf photosynthetic and morphological traits underlie heat stress resilience in northern highbush blueberry (Vaccinium corymbosum L.)

Environmental and Experimental Botany
Northern highbush blueberry (Vaccinium corymbosum L.) is a temperate fruit crop increasingly exposed to heat stress as heatwaves become more frequent. This suggests the need to characterize thermotolerance traits to facilitate sustainable production.

Thermal Stress Is Associated With Fragmentation of Mediterranean Posidonia oceanica Meadows

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
By combining a physiological model of cumulative thermal stress with AI‐based seagrass mapping, we show that chronic sublethal warming is associated with fragmentation of Mediterranean Posidonia oceanica meadows and increased regression risk by 2100. ABSTRACT Posidonia oceanica meadows, which underpin Mediterranean coastal ecosystems, are undergoing ...

DETERMINACIÓN DE LA DL50 y TL50 DE EXTRACTOS ETANÓLICOS DE SUSPENSIONES CELULARES DE Azadirachta indica SOBRE Spodoptera frugiperda DETERMINATION OF THE LD50 AND THE LT50 ETHANOL’S EXTRACTS OF CELLULAR SUSPENSIONS FROM Azadirachta indica OVER Spodoptera frugiperda

Revista Facultad Nacional de Agronomía Medellín, 2008
La obtención in vitro de metabolitos secundarios de neem surge como una alternativa para la posible producción industrial de biocidas. Para la búsqueda de propuestas dirigidas al control de Spodoptera frugiperda, se evaluó la eficiencia de extractos etanólicos de suspensiones celulares de Azadirachta indica para determinar la DL50 y el TL50 sobre la ...
