Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Chromatic number in random scaled sector graphs

open access: yes, 2004
In this paper, we introduce a new model of random graph that we call random sector graph. This model aims to provide a tool for studying communication problems in networks of sensors using laser communication such as the ones addressed in the Smart Dust project.

Programmable luminescent platform based on carbon quantum dots enables wavelength‐multiplexed optical data storage and encryption

open access: yesFlexMat, EarlyView.
A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

open access: yesFlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Solution processed optical modulated silver nanowire top electrode for high performance semi‐transparent organic solar cells

open access: yesFlexMat, EarlyView.
Abstract Silver nanowire (AgNW) top electrodes are pivotal candidates for solution‐processed, semi‐transparent organic solar cells (ST‐OPVs). However, their light utilization efficiency (LUE) typically lags behind that of devices using evaporated metal electrodes, primarily due to the lack of effective optical modulation strategies compatible with ...

Valorizing lemon pomace in bread: Consumer acceptance of fermented and pre‐gelatinized Cardaba banana flour formulations

open access: yesFood Biomacromolecules, EarlyView.
Abstract Whereas gluten‐free bread production often relies on starch‐heavy formulations, this study introduces a novel approach by leveraging the synergistic effects of fermented/pre‐gelatinized Cardaba banana, pigeon pea, and lemon pomace—an underutilized agro‐industrial byproduct.

Litsea cubeba Essential Oil Reduces Postharvest Blueberry Rot by Inducing Cell Membrane Damage and Reactive Oxygen Species Accumulation in Alternaria alternata

open access: yesFuture Postharvest and Food, EarlyView.
Litsea cubeba essential oil (LCEO) reduces blueberry rot while maintaining quality. It disrupts the cellular structure and membranes of Alternaria alternata, causing solute leakage, while simultaneously inducing reactive oxygen species (ROS) accumulation and mitochondrial membrane potential (MMP) damage in the pathogen.

Aloe vera in Food Preservation: Harnessing Bioactive Constituents for Clean‐Label Innovation and Safety Assurance

open access: yesFood Safety and Health, EarlyView.
Aloe vera‐derived biopolymers and nanoformulations enhance antimicrobial, antioxidant, and barrier functions in clean‐label edible coatings and films, whereas safety‐critical anthraquinone thresholds and regulatory constraints shape their translational potential.
