A ternary Ag/Bi 2 O 3 /g-C 3 N 4 (Ag/BO/CN) photocatalyst was fabricated through a combined solvothermal and photochemical reduction approach for the degradation of ciprofloxacin hydrochloride (CIP). Upon illumination with simulated sunlight, the optimized Ag/BO/CN composite efficiently degraded CIP, resulting in near-complete (98.14%) removal within 100 min. This remarkable property is attributed to a synergetic interaction between the Ag surface plasmon resonance (SPR) effect and the S-scheme heterojunction (between BO and CN). In-situ XPS analysis and work function ( Φ ) calculations confirmed the S-scheme charge migration pathway. In this scheme, an internal electric field (IEF) prompts the reunification of less-reactive charge carriers, thereby selectively retaining the highly reductive electrons (e − ) in the conduction band (CB) of CN and the strongly oxidative holes (h + ) in the valence band (VB) of BO. Quenching experiments and electron spin resonance (ESR) spectroscopy identified superoxide radicals (·O 2 − ) and hydroxyl radicals (·OH) as the primary reactive intermediates. Moreover, the catalyst shows considerable promise for practical deployment, as evidenced by its excellent stability over four consecutive cycles and sustained degradation performance across various real water systems.

Facing the current energy crisis, developing new green energy and advancing high-quality energy development are crucial, as multimetal sulfide semiconductors have great potential in photoenergy conversion. This study prepared a carbon-containing bimetallic phosphide (NiCoP@C) cocatalyst from a CoNi-based MOF, which was combined with ZnIn 2 S 4 (ZIS) hollow nanoflowers to enhance electrical conductivity and photocatalytic hydrogen production of the composite. XPS shows electron cloud density of ZIS increases in the composite via interfacial electronic reconstruction. FESEM reveals NiCoP@C nanoparticles are evenly anchored on surface and interlayer gaps of ZIS, forming a hierarchical heterostructure with more active sites. Performance tests show Z-NiCoP@C has a photocurrent density of 129.58 μA cm −2 (vs. 34 μA cm −2 of unmodified ZIS). Under 10 W visible light with 10% TEOA as a sacrificial agent, 10-h cumulative H 2 yield of the composite is 19.52 mmol g −1 , with a H 2 evolution rate of 1.95 mmol g −1 h −1 , 7.8-fold that of pristine ZIS (0.25 mmol g −1 h −1 ).

Quantum dot light-emitting diodes (QLEDs) have emerged as strong contenders for next-generation display technologies. However, the commercialization of blue QLEDs has been severely hindered by the inherent wide band gap of blue quantum dots (QDs), which results in a high hole injection barrier and imbalanced carrier injection. Herein, we demonstrate high-efficiency and high-luminance blue QLEDs by engineering gradient core/shell ZnCdSe/ZnSe/ZnSeS/ZnS QDs with a ZnSe intermediate shell layer. The ZnSe interlayer not only effectively passivates surface defects but also facilitates balanced carrier injection. This strategy achieves a remarkable maximum luminance of 54,554 cd m–2 and an external quantum efficiency (EQE) of 20.6%, representing a significant advancement in device performance. This work provides a strategy for developing high-performance blue QLEDs.

Infected wound healing remains a major clinical challenge because antibacterial control, immune regulation and tissue regeneration are rarely achieved in a coordinated manner. Here we report a digitally light-processed (DLP) 3D-printed hydrogel integrating a ZIF-8@tannic acid@MXene nanozyme within a gelatin methacrylate (GelMA)/chitosan methacrylate (CSMA) matrix (ZGC) for spatiotemporally controlled wound therapy. The DLP strategy enables high-fidelity fabrication of mechanically compliant dressings with interconnected pores and complex architectures. Under near-infrared irradiation, the ZGC hydrogel exhibits efficient photothermal conversion (47.3%) and achieves rapid bacterial eradication (>99.9%) against Staphylococcus aureus and Escherichia coli . Mechanistically, the nanozyme mediates dynamic regulation of reactive oxygen species and inflammatory signalling, thereby synchronizing antibacterial action with immune resolution and tissue regeneration. In a rat infected full-thickness wound model, ZGC plus near-infrared treatment accelerates wound closure to a residual wound area of <2% by day 14, accompanied by enhanced collagen deposition, neovascularization and reduced inflammatory marker expression, without detectable systemic toxicity. These findings establish a DLP-printable, immuno-instructive nanozyme hydrogel as a translational platform for advanced and potentially personalized wound care. Statement of significance Infected wound healing remains a major clinical challenge because current therapies rarely achieve simultaneous control over bacterial burden, oxidative stress, and immune dysregulation. Existing photothermal or antibacterial hydrogels typically emphasize pathogen eradication but overlook the spatiotemporal coordination of immune resolution and tissue regeneration, while conventional 3D-printed scaffolds lack intrinsic immunomodulatory function. In this work, we introduce a digitally light-processed (DLP) 3D-printed nanozyme-integrated hydrogel that unifies precise structural programmability with material-driven immunoregulation. By integrating a ZIF-8@tannic acid@MXene nanozyme within a GelMA/CSMA printable network, the system achieves on-demand photothermal antibacterial activity, dynamic ROS homeostasis, and gene-level modulation of inflammatory and regenerative pathways. Unlike prior reports that rely on drug loading or single-mode antibacterial mechanisms, this platform demonstrates that engineered heterojunction nanozymes embedded in DLP-printed hydrogels can function as immuno-instructive materials, synchronizing infection control with accelerated tissue repair. Transcriptomic analyses further reveal that the hydrogel actively reshapes MAPK-centered inflammatory networks toward regeneration, providing mechanistic insight beyond phenotypic healing outcomes. This study establishes a new paradigm for precision wound therapeutics that bridges advanced additive manufacturing, nanozyme catalysis, and immune engineering, offering broad interest to readers in biomaterials, biofabrication, and translational regenerative medicine.

Hydrogel-based solar interfacial evaporation for seawater desalination is limited by inadequate evaporation rates and inefficient light harvesting, particularly under non-perpendicular illumination. Herein, This study introduces a peony-like single-layer graphene oxide (SLGO)/polyvinyl alcohol (PVA) 3D hydrogel evaporator (GPH) featuring a geometric light-trapping architecture. By exploiting synergistic edge curvature gradients and surface aperiodic wrinkles, the GPH induces multiple internal reflections to effectively manipulate the optical path, thereby overcoming the light absorption limitations of conventional evaporators under oblique incidence. Beyond optical management, precisely tuning the SLGO/PVA ratio optimizes the polymer network's hydrogen bonding, which elevates the intermediate/free water ratio to 0.78 and drastically reduces the water evaporation enthalpy to 1248 J g −1 (cf. 2450 J g −1 for bulk water). Consequently, an exceptional evaporation rate of 2.761 kg m −2 h −1 (20% enhancement over conventional homogeneous hydrogels) and energy efficiency of 91.61% are achieved under 1-sun intensity. Crucially, the hierarchical 3D porous architecture facilitates rapid water replenishment and efficient ion diffusion, endowing the evaporator with robust salt-rejection capabilities. Moreover, the GPH demonstrates outstanding mechanical robustness, with a high fracture strain of 800% in uniaxial tensile tests, indicating its resilience and potential for practical application. This work presents a promising pathway for efficient, reliable seawater desalination and offers a novel perspective for next-generation interfacial solar evaporation technologies.

The red spectral band plays a crucial role in plant growth. Due to the significant absorption peaks of chlorophyll A and chlorophyll B in the red wavelength range of 640-660 nanometers, red photons can be effectively absorbed by these pigments, thereby promoting photosynthesis. In previous studies, we synthesized warm white LED lights for plants, but the spectral peak was near orange-yellow, so the effect on promoting photosynthesis was not significant. Since the traditional coating process usually requires high-temperature sintering, and commercial red phosphor powder CaAlSiN 3 : Eu sintered in an air atmosphere would be oxidized and thus reduce the luminous efficiency. Therefore, this work introduced a non-sintering coating strategy, using a curable epoxy-based slurry and spray coating technology to prepare phosphor films without the need for high-temperature treatment, thus avoiding the oxidation of commercial CaAlSiN 3 : Eu phosphor powder under high temperature. In this experiment, four spatial layouts of phosphor powders were prepared. It was found that the layered structure was superior to the mixed structure because it reduced the occurrence of reabsorption, supplemented the red spectral band, and retained the yellow-green emission. Under the excitation of a 30 W LED source, the surface temperature of all samples remained below 90 degrees Celsius, far lower than the thermal quenching temperature of the phosphor. Optical property analysis confirmed that this layered phosphor powder film not only enhanced the supplementary effect of the red spectrum, but also significantly improved the color reproduction index (Ra = 86.5, R9 = 93.5, R14 = 91.9). In the plant growth experiment, the average SPAD value of the lettuce samples irradiated with the optimized film was 40.0, which exceeded the natural light (26.0) and the previous experimental results (29.1), proving the practical application value of the proposed layered optical coating structure in promoting photosynthesis.

Ultrasmall perovskite CsPbBr 3 quantum dots (QDs) with blue emission are promising materials for light-emitting diodes (LEDs). However, achieving room-temperature synthesis of blue-emitting CsPbBr 3 QDs with long-term stability remains a major challenge, hampering their real-world applications. Herein, we report a novel room-temperature strategy for synthesizing highly stable, blue-emitting CsPbBr 3 QDs, achieved with cross-linked network structures—marking a significant advancement over conventional approaches. Polymer (dimethyl siloxane dimethyl vinyl terminated (PDMS)) cross-linked by curing agent (dimethyl methyl hydrogen siloxane) offers networks that control the size of CsPbBr 3 QDs around 5 nm. The networks inhibit the fall-off of ligands from the QD surface, which restrains the agglomeration of QDs and mitigates thermal quenching of light emission. The CsPbBr 3 QDs with a photoluminescence quantum yield (PLQY) of 93% remain monodispersed in solution over 30 days. The QD-based films retain 95% of their initial PLQY after thermal treatment at 120°C. Blue-emitting CsPbBr 3 LEDs with an emission of 472 nm and a full-width at half-maximum (FWHM) of 23 nm exhibit a peak luminance of 4096 cd m −2 and an excellent operational half-lifetime ( T 50 ) over 38 h at 100 cd cm −2 , the longest-lifespan perovskite blue-quantum-dot LEDs reported to date.

Light-responsive proton conductors represent an attractive research direction owing to their potential in intelligent devices and responsive sensing applications. Herein, we present a cooperative functionalization strategy to construct an MOF-based light-regulated proton-conducting material, MOF-808-AZOA-IL, by integrating azobenzene-4,4′-dicarboxylic acid (AZOA) and an ionic liquid (IL) into the MOF-808 framework. AZOA serves as a photoactive unit to endow light responsiveness, while the IL molecules form a continuous proton-conducting network, enhancing the concentration and mobility of protons. This synergy results in a proton-conduction on/off ratio up to ∼2000 of MOF-808-AZOA-IL, with excellent stability over repeated UV light on/off cycles. This work demonstrates that the incorporation of AZOA and IL synergistically enhances the light-regulated proton conduction of MOF-808, offering a reliable strategy for designing advanced stimuli-responsive proton-conductive systems.

Perovskite light-emitting diodes (PeLEDs), characterized by their excellent optoelectronic properties, including high color purity, flexibly tunable emission wavelengths, and relatively high photoluminescent quantum yields, make them suitable for next-generation display technologies. This study investigates and demonstrates that PeLEDs using a PEDOT:PSS/LiF composite hole transport layer (HTL) can achieve enhanced device performance. When 1.0 mg mL −1 of LiF is added, the device attains a maximum luminance of 8317 cd m −2 and a maximum current efficiency of 8.09 cd A −1 , representing improvements of 163% and 92% respectively compared to the reference device. Analysis reveals that the introduction of LiF can optimize the morphology of the perovskite film and passivate defects within it. Additionally, it helps modulate the work function of PEDOT:PSS and enhance its electrical conductivity, thereby improving hole injection efficiency and further boosting the performance of the PeLEDs. The findings presented in this study can provide a reference for the optimization of PeLEDs.

Realizing stable and scalable perovskite solar cells (PSCs) under real-world outdoor conditions remains a challenge for deployment. Here we report a strategy to improve the resilience of the grain boundary, achieving simultaneous improvement in the power conversion efficiency and long-term operational durability under realistic light cycling and ultraviolet exposure of PSCs. By integrating photoswitchable isomers at grain boundaries, we suppress lattice bond rupture and defect accumulation during repeated light cycling through light-triggered dynamic damage release. This approach stabilizes the triple-cation lead-based perovskite lattice against photoinduced distortions and degradation pathways. As a result, the PSCs retain over 95% of their initial performance after 2,000 h of ultraviolet-containing light cycling at 65 °C and 500 thermal cycles between –40 °C and 85 °C, and deliver a power conversion efficiency of 27.2% (certified as 26.9%). Our strategy improves the operational stability and commercial viability of triple-cation perovskite photovoltaics.

Charred historical papers carry invaluable cultural heritages but are extremely fragile, making rescue research and rescue conservation urgent and important tasks. To clarify the light angle-dependent visibility mechanism of charred historical papers dated 603–655 AD unearthed from the Tangchaodun Ancient City Site in northwest China and develop effective rescue conservation strategies, we conduct comprehensive analyses including radiocarbon dating, FTIR, Raman spectroscopy, SEM observation, optical characterization, and reinforcement experiments. The Charred historical papers were made from bast fibers with kaolinite fillers, showing complete degradation of cellulose. Light angle-dependent visibility of characters originates from synergistic optical differences such as whiteness, reflectance, glossiness and distinct reflection modes between paper and character regions, including specular for paper substrates and scattering for character regions. Specifically, the enhanced scattering in the character regions is attributed to the rough ink layer coating the surface of paper fibers. A 1.0 wt % sodium carboxymethylcellulose (CMC-Na) solution effectively reinforces the fragile papers without altering their appearance or obscuring character information, outperforming common Japanese Tengujo papers. This study provides scientific insights into charred paper relics and a practical conservation method, herein having been successfully applied to over 3000 fragments, which holds broad significance for the study and conservation of charred cultural relics.

Phase segregation under light illumination in mixed-halide perovskite has attracted widespread attention. Meanwhile, the morphology of perovskite films plays an important role in the crystallinity, optoelectronic properties and device performance. Yet, the influence of morphology on phase segregation has not been systematically investigated. Here, we fabricate perovskite films with different surface morphologies and monitor the evolution of phase segregation under in situ illumination using multiphysical field luminescence imaging microscopy. Compared with flat films, the phase segregation in wrinkled films is significantly suppressed, which can be attributed to the release of the internal compressive stress. Furthermore, we propose a polaron-mediated phase segregation mechanism regulated by residual stress. Based on this model, we explain that perovskite films with different morphologies exhibit distinct phase segregation rates. These microscopic findings are critical for understanding the influence of strain on the phase segregation and guiding the future development of more stable wide-bandgap perovskite optoelectronic devices.
