This work successfully synthesized a series of ZnS/CdS photocatalysts (ZC) via one-step hydrothermal method, in which ZC-1 (Zn/Cd = 2:1) exhibited optimal photoreduction performances of hexavalent uranium (U(VI)). The experiments results demonstrated that the reaction rate constant of ZC-1 (k = 0.0174 min −1 ) was 4.49 and 23.51 times higher than those of pristine ZnS and CdS, respectively, confirming that the combination of ZnS and CdS was a feasible strategy for remarkably strengthening the activity of U(VI) photocatalytic reduction. Meanwhile, ZC-1 reached high removal efficiency of 80.18% with an initial U(VI) concentration as high as 180 mg/L, posing a considerable U(VI) extraction capacity of 1443.26 mg/g, which was larger than numerous photocatalysts. The wonderful performances of ZC-1 might be due to its well-dispersed morphology and optimized band structure, which not only provided rich active sites, but also endowed ZC-1 with enhanced capacity of visible light harvesting and photogenerated electron-hole separation. In addition, ZC-1 demonstrated exceptional anti-interference ability and outstanding photocatalytic stability, maintaining a high U(VI) photoreduction rate of over 88% after 5 cycles. The mechanistic study showed that the effective extraction efficiency of U(VI) for ZC-1 was ascribed to the “cooperative capture and directional reduction” mechanism: The built-in electric field concentrated reductive electrons at catalytic active sites to facilitate the U(VI) reduction process, while the well-dispersed of ZC-1 synergistically enhanced UO 2 2+ capture. This study established a novel design strategy and fundamental theoretical framework for developing efficient and stable photocatalytic materials to deal with U(VI) pollution.

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.

Light irradiation modulates aroma/color-related chemical markers of freshness. • Low-temperature yellow light yields the favorable aroma-related chemical profile. • Yellow light promotes deglycosylation of aroma precursors during spreading. • Yellow light irradiation increases the abundance of free aroma compounds. Enshi Yulu is a traditional Chinese steamed green tea characterized with pronounced green color attributes. However, relatively weak aroma characteristics restrict its development, and the mechanisms governing aroma development in steamed green teas remain insufficiently understood. This study aimed to optimize aroma development of Enshi Yulu by evaluating the effects of light spectrum and temperature during spreading. Among the result, yellow light treatment promoted aroma formation, increasing the abundance of key aroma-active compounds (35,216 vs. 26,430 ng/g in the control), and key odorants such as geraniol (12,533.28 ng/g). This effect was associated with enhanced glycosidase activity (128.4 vs. 76.72 U·h/mg protein), facilitating the hydrolysis of glycosidically bound aroma precursors and the subsequent formation of volatile aroma compounds. In addition, yellow light treatment optimally preserved chlorophyll content (1.73 vs. 1.37 mg/g), maintaining desirable green color attributes. This study provided an effective strategy for aroma quality enhancement in Enshi Yulu production. Download: Download high-res image (133KB) Download: Download full-size image

In China, tourism development is a crucial approach to poverty alleviation. With the consolidation of poverty alleviation achievements and the promotion of rural revitalization, it is of great significance to explore the relationship between tourism development and poverty alleviation from the perspective of multidimensional poverty. Therefore, this study took 28 key assistance counties for rural revitalization in the Sichuan–Chongqing region (hereinafter referred to as “key counties”) as the research objects, introduced NPP-VIIRS nighttime light (NTL) data, and a coupling coordination degree (CCD) model to explore the coordination relationship and mechanism between them. The results showed that from 2015 to 2020, the tourism development index (TDI) and estimated comprehensive development index (ECDI) of the key counties increased by 112.57% and 115.12%, respectively. In addition, the spatial differences in tourism development and multidimensional poverty both showed a narrowing trend. According to the results of the CCD model, the key counties basically faced coordination obstacles in the early stage, which were mainly transformed into reluctant coordination and moderate coordination in the later stage. This indicated that tourism poverty alleviation showed a coordinated development trend overall. However, the study also found that there may not be synchronicity between tourism development and poverty alleviation and analyzed the mechanism of their interaction. Overall, the study confirmed the positive impact of tourism development on alleviating multidimensional poverty. In addition, the study found that measuring multidimensional poverty based on NTL data has a high accuracy and can provide support for poverty research. These research results have an important reference value for China to carry out sustainable tourism poverty alleviation and comprehensively promote rural revitalization.

The extensive exploration and exploitation of petroleum resources have precipitated severe marine oil pollution, necessitating advanced strategies for efficient and sustainable remediation. The existing aerogel composites are widely used to deal with the oil leakage. However, the traditional aerogel composites have faced several problems such as lower mechanical properties or less oil adsorption. To address these difficulties, this study proposes a novel three-dimensional (3D) foam/aerogel composite material engineered for high-performance offshore crude oil spill mitigation. The composite was fabricated by integrating a mesoporous aerogel filler into a mechanically robust foam scaffold, synergistically combining the structural durability of foams with the exceptional adsorption capacity of aerogels. This structural design makes the foam composites equipped with enough mechanical properties. Moreover, with the coordination effect of carbon nanotubes, the composite surface rapidly attained temperatures exceeding 100 °C within 5 min under natural sunlight irradiation, effectively reducing crude oil viscosity and enhancing adsorption kinetics. This photothermal activation amplified crude oil adsorption capacity by up to 61-fold compared to conventional adsorbents, enabling accelerated oil recovery. The composites demonstrated versatile adsorption capabilities for diverse substances across density gradient, which achieving the maximum capabilities of 38.6 g·g⁻ 1 for mechanical oil 10 and 31 g·g⁻ 1 for petroleum, while the aerogel incorporation significantly improved mechanical strength (compressive resistance up to 48.31 kPa) and surface hydrophobicity (water contact angle ~ 131°). This multifunctional architecture presents a promising solution for environmentally adaptive, energy-efficient marine oil spill remediation.

Photodetectors (PDs) are critical parts of visible light communication (VLC) systems for achieving efficient photoelectronic conversion and high-fidelity transmission of signals. Antimony sulfide (Sb2S3) as a nontoxic, high optical absorption coefficient, and low-cost semiconductor becomes a promising candidate for applications in VLC systems. Particularly, Sb2S3 PDs were verified to have significantly weak light detection ability in the visible region. However, the response speed of Sb2S3 PDs with existing device structures is still relatively slow. Herein, through optimizing the device structure for the p–i–n type PDs, a p-type Sb2Se3 hole transport layer (HTL) is designed to enhance the built-in electric field and to accelerate the migration of photogenerated carriers for the high responsivity and fast response speed. The optimal thickness of the structure is obtained through the simulation of SCAPS-1D software, and the optimized devices show high-performance parameters, including a responsivity of 0.34 A W–1, a specific detectivity (D*) of 2.20 × 1012 Jones, the −3 dB bandwidth of 440 kHz, high stability, and the value of the Sb2S3 PDs can reach 60% in the range of 360–600 nm, which indicates that the device is very suitable for working in the visible light band. In addition, the resulting Sb2S3 PD is successfully integrated into VLC systems by designing a matched light detection circuit. The results suggest that the Sb2S3 PDs are expected to provide an alternative to future VLC system applications.

Developing environmentally friendly, stable, and narrow and direct band gap halide perovskite materials has attracted substantial interest because of their wide range of potential applications. Here, an all-inorganic Pb-free halide double perovskite, Cs2NaVCl6, was prepared by the solid-state reaction method and hydrothermal method. Cs2NaVCl6 crystallizes in the cubic Fm3̅m space group with the unit parameter a = 10.3497(14) Å. The combined density functional theory and experimental study demonstrates that the compound is a direct band gap semiconductor with a band gap of ∼2.64 eV. More importantly, it exhibits strong visible and near-infrared light absorptions and markedly ambient and thermal stability.

An artificial synaptic device that can provide color discrimination, image storage, and image recognition is highly required to mimic the human vision for biological robots. All-inorganic halide perovskites have attracted extensive attention for the reason of their high stability and favorable photoelectric properties. In this study, a light-stimulated synaptic phototransistor based on a CsPbBr3/organic semiconductor hybrid film is reported. The fabricated CsPbBr3 film exhibits an island structure, which reduces the hysteresis effectively and at the same time achieves a high specific detectivity of up to 2 × 1015 Jones. The decay of the photocurrent can be delayed by changing the gate bias, which is essential for achieving high-performance light-stimulated synaptic devices. Due to the outstanding detectivity of the device, the obvious synaptic functions can be observed when triggered by a light signal with a power of 1.6 nW that is much weaker than previous most perovskite-based hybrid synaptic phototransistors under a low operating voltage of −1 V. The electrical power consumption of the device could be as low as 0.076 pJ when the power of light spike was 7.36 nW. Taking into account this characterization, with changing of light intensity or wavelength, the contrast of the image was enlarged, which can further promote the image recognition accuracy. More significantly, this CsPbBr3/TIPS hybrid film can be fabricated by facile and low-cost solution processes. This study indicates the great potential of solution-processed perovskite-based light-stimulated synapses for future artificial visual systems.

Nonlinear optical (NLO) materials have recently aroused great interest owing to their capability of frequency conversion in solid-state lasers. Herein, we report an acentric zinc germanate K2ZnGe2O6 obtained successfully through spontaneous crystallization methods. It affords a novel three-dimensional (3D) framework comprised of [GeO4] and [ZnO4] motifs with K atoms located in the tunnels. K2ZnGe2O6 displays a moderate second-harmonic-generation (SHG) intensity (0.73 × KDP) with phase-matchable behavior. Optical characterization demonstrated that it has a UV cutoff edge located at 368 nm with a large energy band of 3.23 eV, accompanied by a wide transmission window, covering a 3–5 μm atmospheric window. Moreover, thermal properties implied that it possesses intriguing thermal stability of 987 °C and a congruent melting nature. Additionally, first-principles calculations unveiled that the NLO performance was primarily attributed to the collective effect of [GeO4] and [ZnO4] building units. These findings indicate that K2ZnGe2O6 is a potential NLO crystal.
