Natural photosensitizers are promising for postharvest fruit preservation, but their antibacterial efficacy is often limited by weak visible-light responsiveness. Based on the natural photosensitizer quercetin, this study prepared an Fe-quercetin coordination complex (QF), which was subsequently incorporated into an edible coating with a pectin matrix for the preservation of strawberries. DRS-Tauc analysis showed that iron coordination reduced the bandgap of quercetin from 2.64 eV to 1.86 eV, and EPR analysis confirmed the generation of 1 O 2 , •O 2 − , •OH, and HO 2 • under illumination. Under visible-light irradiation, QF completely inactivated Staphylococcus aureus at 0.2 mg/mL within 10 min and Escherichia coli at 0.3 mg/mL within 5 min, whereas free quercetin was markedly less effective under the same conditions. In strawberries stored at 25 °C for five days, the QF-P coating delayed spoilage, reducing weight loss from approximately 16.63% to approximately 7.95%, while maintaining a firmness of approximately 242 g. QF-P coating also better preserved the pH, total soluble solids and color of strawberries during storage. These results show that iron coordination is an effective way to improve the visible-light-driven antibacterial activity of quercetin and support the use of QF-based edible coatings for preserving perishable fruits under mild conditions.

CO2 reduction to light olefins is an important pathway toward carbon neutrality, but it is hindered by low thermodynamic conversion and the inherent trade-off between activity and selectivity. To address this challenge, a bifunctional catalyst consisting of Cu single atoms anchored on ZrO2 and SAPO-34 (Cu1/ZrO2-SAPO-34) was developed. This catalyst achieves 84.3% light olefin selectivity and 15.0% CO2 conversion, with stable performance maintained over 100 hours. In this catalyst, Cu single atoms, ZrO2, and SAPO-34 exhibit clear division of labor and synergy, responsible for CO2 activation, active site stabilization, and olefin selectivity control, respectively. Mechanistic investigations using in situ DRIFTS and DFT calculations demonstrate that the interaction between Cu single atoms and ZrO2 facilitates the further hydrogenation of formate intermediates to methoxy species, while reducing the energy barrier for methoxy hydrogenation to methanol, thus ensuring high light olefin selectivity in subsequent conversion over SAPO-34. This work provides new insights for CO2 conversion and the design and application of single-atom catalysts in tandem catalytic reactions.

A temperature/light dual-stimuli-responsive polymeric carrier PPEGMA-b-PNIPAM-hv-PMAA-b-PS was designed and synthesized through host-guest mutual recognition, and further applied for pectinase immobilization. Both the host molecule PPEGMA-b-PNIPAM-β-CD and the guest molecule PS-b-PMAA-Azo were prepared via ATRP, hydrolysis, and click chemistry, respectively. The characterization of polymeric structure and morphology was carried out by 1H NMR, FTIR, and GPC. This polymer could self-assemble into spherical micelles in aqueous media, the critical micelle concentration (CMC) and the micellar morphology were also examined by UV–Vis, TEM, DLS, fluorescence spectra, etc. The enzyme immobilization property of the enzyme carrier was investigated too. It was revealed when pH was 4.0, immobilization concentration was 8 U/mL, temperature was 25 °C, and immobilization time was 60 min, both the immobilized amount and the relative activity could reach the maximum. By comparison with free pectinase, immobilized pectinase had a better tolerance to the variation of temperature and pH, and enhanced storage stability and reusability. Moreover, the relative activity of immobilized pectinase could be easily regulated by adjusting the temperature or UV irradiation. So, we can predict this immobilization material has a great application potential in industrial catalysis.

The combination of three-dimensional (3D) imaging and hyperspectral imaging has been demonstrated to provide significant information about the scene, thereby facilitating enhanced perception and comprehension of the underlying structure of the real world. In response to the inadequate utilisation of the physical potential of 3D geometric information in current multimodal data fusion research, a structured-light three-dimensional hyperspectral imaging system (STHS) and a hyperspectral data correction method based on 3D geometry were proposed, and their application value in the analysis of plant physiological parameters was systematically explored. The system integrates structured-light 3D reconstruction, hyperspectral imaging, and illumination modules, achieving sequential acquisition and fusion of 3D and hyperspectral data within the 473–900 nm spectral range. It demonstrates a topographic accuracy of 0.04 mm at 800 mm working distance, 7 nm spectral resolution, and 0.98 Structural Similarity Index (SSIM) registration accuracy. An innovative reflectance correction model based on a Multilayer Perceptron-based Reflectance Correction (MLP-RC) was developed, which physically correlates geometric features with spectral response and reduces spatial non-uniformity to 1.1%. Compared with Lambertian correction and white-board correction, the standard deviation obtained using the MLP-RC model is significantly smaller than those of the other two methods, demonstrating its superior capability in restoringreflectance consistency. Leveraging the corrected data, we achieved three-dimensional visualization of chlorophyll distribution in plant leaves, revealing heterogeneous distribution patterns within complex structures. Destructive biochemical experiments were conducted on multiple plant species to validate the reliability of the system for estimating chlorophyll content. This geometry-constrained spectral correction substantially improves the accuracy of plant phenotype analysis and provides a novel technical solution for precision agriculture monitoring.

The photothermal effect holds considerable promise for applications in food sterilization and preservation. Mesoporous polydopamine (MPDA), a green photothermal material with high drug-loading and sustained-release properties, was loaded with carvacrol (Car) to prepare MPDA-Car nanoparticles, which were incorporated into a PVA/Gel matrix to fabricate a multifunctional film with synergistic photothermal and Car's broad-spectrum antibacterial activity. Near-infrared (NIR) irradiation-induced photothermal effect directly damaged bacterial membranes and triggered controlled Car release from MPDA mesopores, enhancing antibacterial efficacy. Characterization confirmed that uniform MPDA-Car dispersion significantly improved the film's mechanical strength (tensile strength: 22.14 MPa, elongation at break: 218.36%) and reduced water vapor permeability (WVP) by 32.7% compared with the pure PVA/Gel film. The film also exhibited excellent antioxidant capacity (DPPH: 74.4%, ABTS: 77.9%) and potent inhibition against Staphylococcus aureus and Escherichia coli . In Chinese shrimp preservation, the 1.00% PG-MC film mitigated weight loss, retarded TVB-N and TBA accumulation, inhibited pH elevation, and extended shelf life by over 2 days. Notably, MPDA-mediated mild photothermal heating caused no significant degradation of shrimp soluble protein or LOX activity, retaining nutritional quality. This film provides a promising strategy for developing eco-friendly food packaging materials.

Fast-responsive and efficient perovskite QD-based light-emitting diodes (QLEDs) demonstrate significant potential in high refresh rate display applications. However, the response time and external quantum efficiency (EQE) remain limited by imperfect device architectures, including low carrier mobility in transport layers and severe interface losses. Here, we utilized a molecule (3-(6-(3-(4,6-di([1,1′-biphenyl]-4-yl)-1,3,5-triazin-2-yl)phenyl)pyridin-2-yl)phenyl) diphenylphosphine oxide (ETL-PO) as an electron transport layer (ETL) due to its high electron mobility, which could also reduce defects at the interface between the QDs and ETL in the perovskite QLED. The P═O group of ETL-PO coordinates with undercoordinated Pb 2+ to suppress nonradiative interfacial recombination, while the conjugated backbone supports efficient electron transport and reduces the device's resistance and capacitance. Resultantly, the QLEDs based on ETL-PO exhibit a total response time of 564 ns at an active area of 0.01 mm 2 , which is more than 50 times faster than that of 29 µs for control devices. Furthermore, a peak EQE of 22.8% with a maximum luminance of 105518 cd m −2 is reached. This work shows a perovskite QLED device successfully achieved both high EQE and nanosecond-level response time, providing a new perspective for the field of optical communication and data transmission.

Red perovskite quantum dots are critical for the next generation of micro-LED displays, yet their commercialization is thwarted by poor color purity and operational instability. Here, we report a novel, one-step fabrication of a flexible perovskite quantum dot nanopaper (PQDnP) that overcomes these challenges through a synergistic, multi-scale stabilization mechanism. We replace conventional surface ligands with a dual-component system: a sustainable cellulose nanocrystal matrix acts as a robust, thermally insulating scaffold, while a phenethylamine cation provides atomic-level surface passivation and induces the formation of a protective quasi-2D perovskite shell. This hierarchical design yields pure-red PQDnPs with a stable photoluminescence (PL) at 621 nm and a ultra-narrow spectral linewidth of less than 30 nm. The resulting nanopaper demonstrates outstanding robustness, including superior thermal stability and excellent photostability, retaining 74% of its PL intensity after 24 h under harsh blue-light irradiation (150 mW/cm 2 ). By integrating the PQDnP as a color converter with a vertically stacked blue/green μ-LED array, we demonstrate a white-light device with a high system external quantum efficiency of 4.5% and a high peak luminance of over 26,000 cd/m 2 . This bio-inspired, scalable approach provides a practical solution to the persistent “red gap” problem, paving the way for high-fidelity perovskite-based micro-displays.

The inherent nonlinearity and limited multimodal sensing capabilities of conventional flexible sensors hinder their applications in complex scenarios such as wearable health monitoring and human-machine interaction. Here, a fully solid-state sensor based on MXene/silk fibroin (SF) composite membrane is proposed, which features expanded interlayer spacing and enhanced mechanical strength, achieving a linear and self-powered conversion of both pressure- and light-driven ionic conversion to electrical responses. In force-electric conversion mode, the current and voltage sensitivity of the obtained pressure sensor with solid electrolyte can reach 2.667 mA m −2 kPa −1 and 0.083 mV kPa −1 , respectively. In light-electric conversion mode, the switching ratio of current is as high as 2658.0, and the response time is as fast as 25 ms. The dual-mode synergy was successfully applied to wearable physiological monitoring, acoustic wave recognition, image recognition, and information encryption, establishing a new paradigm for next-generation bionic sensing systems.

White light-emitting diodes (WLEDs) play a crucial role in solid-state lighting technologies. Among the key factors contributing to their performance, the development of high-quality cyan phosphors is critical in achieving excellent color rendering index (CRI) and stable long-term operation. In this study, a cyan-emitting phosphor, NaBa 2 Al(P 2 O 7 ) 2 : x Eu 2+ ( x = 0.01-0.06), was explored. The material's structures, morphology, optical behavior, and thermal stability were analyzed. Rietveld refinement reveals that the phosphor exhibits high crystallinity and confirms the successful substitution of Eu 2+ ions into Ba 2+ sites within the crystal lattice. Upon excitation at 320 nm, the phosphor emits broad, asymmetric cyan light, with peak intensity occurring at an Eu 2+ concentration of 0.03 achieving internal quantum efficiency (IQE) of 68.9%. Energy transfer and Gaussian fitting analyses show that Eu 2+ ions occupy two distinct crystallographic sites, and concentration quenching is attributed to dipole-dipole interactions. The phosphor retains 77% of its intensity at 425 K, with an activation energy of 0.3173 eV, demonstrating high thermal stability and color consistency. When integrated with a red-emitting phosphor onto a 320 nm UV chip, a white light-emitting diode (WLED) is fabricated, exhibiting a correlated color temperature (CCT) of 5727 K and a color rendering index (CRI) of 95.6. These results highlight this phosphor for applications in advanced white light-emitting diode (WLED) technologies across diverse lighting systems.

Oxygen migration on catalyst surfaces is crucial for transforming two greenhouse gases (CH 4 and CO 2 ) into syngas through dry reforming of methane (DRM), as it drives key elementary reactions, generates reactive oxygen vacancies and suppresses carbon deposition. An efficient light-enhanced oxygen-migration strategy was successfully implemented with an Ir/CeO 2 photothermal catalyst in this work. Recordable photothermal catalytic production rates of 6.56 and 8.55 mol·g -1 ·h -1 for H 2 and CO have been achieved at 700 °C with a light intensity of 28 kW·m -2 . Compared with dark conditions, the yields of H 2 and CO under light exposure are increased by 106% and 57%, respectively, with the conversions of CH 4 and CO 2 reaching 50% and 64%. Furthermore, the pivotal role of the pronounced oxygen-migration-mediating capability of Ir clusters supported on CeO 2 has been unveiled by integrating theoretical calculations with a suite of in-situ characterizations. Photogenerated electrons transfer from CeO 2 to the Ir species, enhancing their ability to induce oxygen migration and generate oxygen vacancies, thereby leading to a significant increase in photothermal catalytic DRM performance. This work not only successfully developed an efficient photothermal catalyst for DRM but also proposed an innovative view to inspire the mechanism of light-enhanced catalysis based on oxygen migration.

Metal halide double perovskite Cs₂AgInCl₆, as an environmentally friendly direct-bandgap semiconductor, emerged as a strong candidate for a new generation of environmentally friendly and stable photocatalysts due to its long carrier lifetime, non-toxicity, and moisture resistance. However, due to parity-forbidden transitions and high sensitivity to water, achieving higher-efficiency photocatalytic degradation in water remained an urgent challenge. Our study presented for the first time a high-entropy Cs 2 AgInCl 6 material Cs₂(Na₁/₂Ag₁/₂)(Mn₁/₃In₁/₃Bi₁/₃)Cl₆ (ANIBM DPNCs), which exhibited a remarkable visible light responsive and applicable to degrade pollutants in aqueous environments. In comparison with existing photocatalysts within the halide perovskite family, ANIBM DPNCs has been shown to exhibit higher photocatalytic efficiency and to demonstrate low sensitivity to various environments such as water and oxygen. Within 30 min, the RhB (10 mg/L) was completely degraded, while demonstrating comprehensive phase stability. Following four cycles of reuse and four months of atmospheric exposure, ANIBM DPNCs exhibited no structural alteration and retained its original photocatalytic performance. Notably, at elevated temperatures of 483 K, a remarkable resilience was exhibited, with the material retaining its original crystal structure. The results demonstrated that this material can be efficiently synthesized, is non-toxic, and exhibited outstanding photocatalytic performance and stability. This advancement successfully overcame the limitations of Cs 2 AgInCl 6 in photocatalysis, which were previously restricted to ultraviolet response and degradation in ethanol solutions. Our research provided a solid foundation for the transformation of Cs 2 AgInCl 6 from a low-efficiency luminescent material into a high-performance photocatalyst.

WO 3 /Cu 2 WS 4 heterojunction photocatalyst is fabricated by a solvothermal route. • WO 3 /Cu 2 WS 4 displays strong visible-light photocatalytic activity for gaseous styrene degradation. • Optimized composite delivers better degradation efficiency and reaction kinetics than pure components. • Z-scheme charge transfer mechanism is put forward to interpret the elevated photocatalytic activity. In this work, a Z -scheme heterojunction photocatalyst WO 3 /Cu 2 WS 4 was prepared by loading Cu 2 WS 4 particles on the surface of bulk WO 3 . Under simulated visible light irradiation, the catalyst exhibited excellent photocatalytic oxidation performance toward styrene (200 mg/m 3 ). The optimal WO 3 /CWS-20% composite achieved the highest photocatalytic oxidation efficiency for styrene, with a degradation rate of 97.2% and a corresponding rate constant of 0.03651 min −1 , which was 2.8 and 3.2 times higher than those of pure WO 3 and Cu 2 WS 4 , respectively. Moreover, the material possessed good stability, maintaining 83.4% of its degradation efficiency after four consecutive cycles. The electron transfer and catalytic mechanisms of the catalyst were further investigated via photoelectrochemical measurements. The results indicate that the constructed Z -scheme heterojunction can effectively separate photogenerated charge carriers and facilitate the generation of reactive species such as hydroxyl radicals (·OH) and superoxide anion radicals (·O 2 − ). This work offers a novel strategy for designing high-efficiency heterojunction photocatalysts for the degradation of VOCs under sunlight irradiation.
