Summary: The review focuses on organic-inorganic nanocomposites with a significant degree of electronic coupling across the hybrid interface, exploring charge and energy transfer processes for optoelectronic applications. The discussion covers physical chemistry of common organic and inorganic components, deriving synthesis and assembly strategies and design criteria. Future research should aim for improved understanding of binding motifs and molecular orientation at the hybrid interface.

Summary: Researchers have developed a plasmonic OECT device that combines the advantages of OECTs and plasmonic sensors, resulting in high sensitivity for biosensing. The device is fabricated using a simple nanoimprinting process, allowing tuning of plasmonic resonance peak for versatile sensing. Glucose sensing experiments showed a five-fold sensitivity enhancement for the plasmonic OECT compared to a regular OECT, suggesting its potential for sensing a wide range of biomolecules.

Summary: In this study, a plasmonic OECT (POET) device that combines the advantages of organic electrochemical transistors (OECTs) and plasmonic sensors is reported. The device is fabricated through a nanoimprinting process and can be used for sensitive biosensing. With glucose sensing as an example, a five-times sensitivity enhancement is achieved for POET compared to a regular (non-plasmonic) OECT. This opens up new possibilities for optoelectronic sensors that combine the inherent high sensitivity of OECTs and localized plasmonic field to detect a wide range of biomolecules.

Summary: Plasmonic nanoparticles (NPs) were used to enhance photon harvest in organic solar cells (OSCs). By incorporating hybrid silver/silver-oxide (Ag/Ag2O) NPs in the hole transport layer (HTL) PEDOT:PSS, OSCs based on poly(3-hexylthiophene) (P3HT) and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) showed improved conductivity, optical absorption, aggregation, and power conversion efficiency. The significant improvement in the power conversion efficiency was attributed to the synergistic enhancement in exciton generation, dissociation, charge collection, and dissociation probability.

Summary: Plasticulture, the practice of using plastic materials in agriculture, consumes a significant amount of plastics every year. Developing biodegradable plastic materials is crucial for sustainable agriculture. Two types of potentially biodegradable plastic films were prepared and tested, with promising results showing the potential for using disulfide-based polymers as biodegradable materials in agriculture.

Summary: A silicon-based infrared photodetector using an organic nano-dot array covered with an Au thin film is proposed in this study, showing enhanced light absorption of incident infrared light. The experiments demonstrated efficient photodetection in the near-infrared region and carrier excitations between organic semiconductors. The proposed structure provides a foundation for fabricating mid-infrared silicon-based photodetectors with high light absorption performance.

Summary: In this work, the consequences of higher-order field theories on oscillons have been examined. It has been found that by using a generalization of the symmetric double-well potential and a 06 potential, 3 + 1 spherically symmetric oscillons with significantly large lifetimes can be obtained without parameter fine-tuning.

Summary: A tandem postsynthetic modification strategy was developed for Zr-based metal-organic framework (MOF) materials, resulting in well-defined 2-in-1 heterogeneous catalysts with high catalytic activity in the synthesis of cyclic carbonates. Experimental measurements, including DRIFT and solid-state NMR, helped elucidate the role of each component in the catalytic reaction, especially the cooperative effect between Lewis acid sites and the co-catalyst in the heterogeneous system.

Summary: This study investigates the sensitivity of the optical absorption of multilayer graphene structure to subnanometer interlayer separation. The results show that neglecting the interlayer separation leads to upper bounds on the absorption, while finite interlayer separations greatly affect the absorption. A closed-form analytical expression for the absorption is derived for an infinite number of graphene layers. The findings highlight the importance of considering subnanometer interlayer separations for accurate modeling and prediction of the optical properties of multilayer Van der Waals crystals suitable for coherent perfect absorption.

Summary: Researchers have achieved enhanced directionality of photoluminescence emission by placing an organic dielectric film on top of a polymeric fluorophore film. The directive emission is increased by 42% by utilizing the structural coherence in the polymeric fluorophore film and the epsilon-near-zero response in the organic dielectric film. This capability to control directive emission with organic dielectric films is highly useful in applications requiring bio-compatibility of a fluorophore-embedding medium.
