Developing novel materials to improve the global food supply is vital to combat hunger, achieve food security and promote sustainable agriculture. To address this issue, we employed red-emitting Ag-In-S-Zn (AISZ) quaternary quantum dots (QDs) as light converters to fabricate AISZ QDs-loaded ethylene vinyl acetate (EVA) copolymers (AISZ/EVA) films to improve the light conditions for crop growth. The synthesis of AISZ QDs was optimized to achieve a high quantum yield (73%) and an emission band matching the absorption window of chlorophyll a and b. Using EVA resin as the matrix, efficient ultraviolet-to-red light-converting AISZ/EVA films with varying AISZ content were prepared by the solvent evaporation method. The fluorescence and transmittance of these light-conversion films along with a blank EVA control, were characterized. Subsequent 28-day lettuce cultivation under controlled light illumination revealed that the 1.0 wt.% AISZ/EVA film induced maximal growth enhancement. The fresh weight and dry weight were increased by 28.2% and 34.4%, respectively, while the contents of total chlorophyll, chlorophyll a, chlorophyll b, carotenoid, soluble sugars and proteins were increased by 48.8%, 51.3%, 43.8%, 40.8%, 33.6% and 37.2%, respectively. The results demonstrate that broad-emitting AISZ QDs served as efficient light converters to fabricate agricultural light-conversion films, highlighting their broad application prospects and promising commercial potential in controlled environment agriculture.

● S,Fe-NiFeO x H y /NF shows an ultra-low OER overpotential of 305 mV at 1000 mA cm −2 . ● The catalyst exhibits a promising stability for over 40 h without activity decay. ● The total preparation process of S,Fe-NiFeO x H y /NF electrocatalyst only takes 6 min. ● The high performance stems from electronic interactions among S, Fe and NiFeO x H y . Water electrolysis is considered an ideal route for producing high-purity hydrogen, yet its widespread application remains severely constrained by the anodic sluggish oxygen evolution reaction (OER). Herein, we present a high-performance S,Fe-NiFeO x H y /NF electrocatalyst for OER that markedly reduces the overpotential of OER to 196 mV at the benchmark current density of 10 mA cm −2 . Even at high current densities of 500 and 1000 mA cm −2 , the overpotentials are only 291 and 305 mV, respectively, outperforming most previously reported Ni/Fe-based catalysts. The catalyst also exhibits promising long-term stability, maintaining a high current density of 500 mA cm −2 for over 40 h without activity decay. Notably, the entire catalyst preparation takes just 6 min, and this cost-effective and facile synthetic strategy is key to enabling practical water electrolysis. Our findings open up a new avenue for developing non-noble metal catalysts with both high activity and durability for water electrolysis.

A sulfide–sulfide ZnIn 2 S 4 /ZnS heterojunction establishes an S-scheme charge-transfer pathway with intimate interfacial coupling. • Ce act as additional regulation centers to modulate interfacial electronic structure and carrier dynamics. • The S-scheme charge-transfer mechanism is supported by XPS, KPFM, DFT calculations, and ultrafast spectroscopy. • Ce-mediated electronic regulation synergistically enhances CO 2 adsorption, activation, and surface reduction kinetics. • The optimized C2ZZ2 catalyst achieves 140.6 μmol g −1 h −1 CO production through coordinated interface and electronic regulation. Solar-powered photocatalytic CO 2 reduction represents a promising strategy for achieving carbon neutrality through sustainable solar-to-chemical energy conversion. Nevertheless, inefficient charge separation and sluggish interfacial reaction kinetics markedly limit its performance. Herein, Ce-regulated ZnIn 2 S 4 /ZnS S-scheme heterojunctions were synthesized via a facile one-step in situ hydrothermal strategy to regulate interfacial charge transfer and surface reaction processes. The ZnIn 2 S 4 /ZnS interface establishes an S-scheme charge-migration pathway, facilitating directional migration and utilization of photogenerated carriers, while Ce incorporation induces electronic redistribution and modulates the local electronic environment. Experimental investigations combined with theoretical calculations reveal that Ce-mediated electronic modulation cooperates with the S-scheme heterointerface to strengthen CO 2 adsorption, accelerate interfacial charge transfer, and reduce the energy barrier of CO 2 reduction. Benefiting from this synergistic electronic regulation, the optimized C2ZZ2 catalyst achieves a CO evolution rate of 140.6 μmol g −1 h −1 , approximately 4.5-fold higher than pristine ZnIn 2 S 4 . This work provides mechanistic insights into rare-earth-mediated electronic regulation in metal sulfide photocatalysts, offering a deeper understanding of the relationship among electronic modulation, interfacial charge-transfer dynamics, and CO 2 reduction kinetics. An S-scheme heterojunction, in which ZnS nanospheres are anchored to a defect-containing cerium-doped ZnIn 2 S 4 micro-flowers structure (CxZZy composite), was synthesized via a one-step in situ solvothermal method. This material exhibits outstanding CO 2 catalytic performance under visible light irradiation. Download: Download high-res image (118KB) Download: Download full-size image

BiOBr/ZnFe 2 O 4 couples visible-light bisphenol S (BPS) removal with magnetic recovery. • BPS removal at 60 min ranged from 69.2% to 99.0% across four spiked water matrices. • Scavenger and probe tests support oxygen-dependent and radical-mediated oxidation. • BPS removal remained at 95% in the fifth cycle after methanol regeneration. • Residual acute toxicity persisted after near-complete parent BPS removal. Bisphenol S (BPS) removal was investigated using a magnetically recoverable BiOBr/ZnFe 2 O 4 composite under visible-light irradiation. Among four nominal feed mass ratios, ZnFe 2 O 4 :BiOBr = 1:4 gave the highest activity, achieving 97.1% BPS removal within 40 min at a catalyst dose of 1.0 g L −1 and an initial BPS concentration of 5 mg L −1 . Its apparent rate constant of 0.091 min −1 was approximately 2.0 and 14.2 times those of pristine BiOBr and ZnFe 2 O 4 , respectively. The composite exhibited a saturation magnetisation of 28.8 emu g −1 , with visible magnetic clarification by 30 s. Removal at 60 min decreased from 99% to 95% over five cycles involving methanol washing without catalyst replenishment, while the principal crystalline phases were retained. Scavenger responses and terephthalic-acid probe fluorescence supported oxygen-dependent and radical-mediated oxidation. Across four BPS-spiked water matrices, 60-min removal ranged from 99.0% in distilled water to 69.2% in wastewater-treatment-plant effluent. Aliivibrio fischeri luminescence inhibition rose from 13.32 ± 1.17% initially to a highest sampled mean of 31.37 ± 2.70% at 20 min and declined to 22.39 ± 1.36% at 90 min (mean ± standard deviation, n = 3), showing persistent residual acute toxicity despite parent-compound removal. The results demonstrate the combined benefits of visible-light activity and magnetic recoverability, while identifying water-matrix inhibition and residual toxicity as constraints on further process development.

Heterogeneous atomic doping is the mainstream way to enhance the electrochemical performance of porous carbon electrode materials. Herein, a three-dimensional honeycomb-like porous carbon material was synthesized by directly one-step carbonization-activation polyvinyl alcohol hydrogel method. In this study, a N, S co-doped porous carbon material was prepared by introducing thiourea during the hydrogel formation process. The as-synthesized product possesses a large specific surface area and a well-developed porous structure. Notably, the obtained N, S co-doped porous carbon delivers an excellent specific capacitance of 260.5 F g −1 at a current density of 1 A g −1 in a 6 M KOH electrolyte, along with outstanding cycling stability. These values are much higher than those of undoped porous carbon, single N-doped porous carbon, and single S-doped porous carbon. After 10,000 cycles, the material's specific capacitance retention remains stable, with a Coulombic efficiency approaching 100%. This work presents a facile and effective pathway for the electrode rational design of next-generation energy storage devices.

ALP1 is a structurally defined polysaccharide isolated from Amomum villosum T.L. Wu fruits with an average molecular weight of 26.1 kDa. Previous studies have demonstrated that ALP1 promotes growth performance of piglet by regulating proliferation of intestinal epithelial cells. However, the molecular mechanism remains incompletely understood. In the present study, the absorbability of ALP1 by porcine small intestine epithelial cells and regulating mechanism of ALP1 on cell proliferation were investigated. The results showed that ALP1 resists gastrointestinal degradation and is efficiently absorbed by intestinal epithelial cells via endocytosis. Furthermore, ALP1 facilitates cell cycle progression through upregulating expressions of cdk4 and cyclin e , resulting in an increased proportion of cells in the S and G2/M phases. These findings provide insights into the cellular mechanisms underlying the growth-promoting effects of ALP1 and highlight the potential of dietary polysaccharides as functional agents for enhancing animal growth and gut health.

Covalent triazine frameworks (CTFs) possess high conjugation and tunable structures for photocatalysis, but low electron-hole separation and poor stability limit their hydrogen evolution from water splitting. Herein, a new S-scheme heterojunction was effectively created through electrostatic self-assembly of a fluorenone-based covalent triazine framework (FOCTF) with heptazine crystalline carbon nitride (HCN). Staggered band structures were confirmed via Mott-Schottky measurements and UPS characterization, and electron spin resonance (ESR) analysis validated the S-scheme electron transfer pathway. The optimal HCN@FOCTF sample exhibited the highest photocatalytic hydrogen production rate (80.79 μmol h −1 ) at 405 nm, with an apparent quantum yield of 32.51%. Experimental studies confirm that HCN@FOCTF exhibits outstanding photocatalytic performance and stability. The constructed S-scheme heterojunction generates a favorable intrinsic electric field, accelerating directional S-scheme charge carrier transport and thereby enhancing carrier separation and utilization rate. This work proposes a novel idea for constructing an S-scheme heterojunction to regulate electron transfer pathways, towards efficient photocatalytic hydrogen production.

g-C 3 N 5 /BiVO 4 - x heterojunctions with tunable BiVO 4 facet ratios were fabricated. • g-C 3 N 5 /BiVO 4 -F shows best activity via suitable (121)/(040) and (040)/(011) ratios. • H 2 O 2 addition boosts photocatalytic degradation efficiency of ceftriaxone sodium. • In-situ XPS confirms the S-scheme charge transfer in g-C 3 N 5 /BiVO 4 -F heterojunction. S-scheme heterojunctions have garnered significant attention in the photocatalytic degradation of antibiotics due to the efficient charge separation and strong redox capability preservation. However, photocatalytic activity is highly dependent on the exposed crystal facet ratios of the catalyst. A series of g-C 3 N 5 /BiVO 4 (N-CN/BiVO 4 -x) S-scheme heterojunctions were fabricated by tuning the morphology of BiVO 4 into peanut-like (BiVO 4 -P), flake-like (BiVO 4 -F), and decahedral structures (BiVO 4 -B), thereby controlling the ratios of exposed crystal facets. Degradation performance tests revealed the optimal performance of N-CN/BiVO 4 -F. This heterojunction achieved a degradation rate of 71.1% for ceftriaxone sodium (CS). With the introduction of H 2 O 2 , the degradation rate further increased to 85.1%. The results confirmed that the superior performance of N-CN/BiVO 4 -F is closely related to the specific exposure ratios of its (121)/(040) and (040)/(011) crystal facets. Furthermore, in-situ XPS confirmed that the charge transfer follows S-scheme charge transfer mechanism. Photoelectrochemical measurements and radical trapping experiments revealed a possible CS degradation mechanism. This work elucidates how the exposed facets of BiVO 4 regulate the photocatalytic performance of S-scheme heterojunctions. The findings provide a theoretical and practical basis for designing efficient photocatalysis systems. Download: Download high-res image (92KB) Download: Download full-size image

Constructing heterojunctions is an effective strategy to enhance charge carrier separation and photocatalytic performance. In this study, a Bi 4 O 5 Br 2 /InVO 4 S-scheme heterojunction composite was prepared by a solvothermal method. The physicochemical properties were thoroughly investigated using various characterization techniques. Visible-light degradation experiments of ciprofloxacin (CIP) showed that the optimal sample, 5% Bi 4 O 5 Br 2 /InVO 4 (BI-5), exhibited the highest degradation activity (92.77%) along with excellent cycling stability. The effects of different environmental factors on the degradation performance were also systematically studied. The enhanced activity is attributed to the synergistic effect of the S-scheme heterojunction and increased oxygen vacancies. The S-scheme charge transfer, driven by the IEF at the heterointerface, enables spatial separation of photogenerated electrons and holes while preserving strong redox potentials, with reductive electrons accumulating in Bi 4 O 5 Br 2 and oxidative holes remaining in InVO 4 . Meanwhile, the introduction of InVO 4 creates abundant oxygen vacancies. These vacancies act as electron capture centers to suppress bulk recombination, introduce in-gap states that facilitate interfacial charge transfer, and provide additional active sites for surface reactions. Consequently, the S-scheme junction and oxygen vacancies jointly promote the separation, migration, and surface utilization of charge carriers, leading to significantly improved photocatalytic performance.

Emulsified oily wastewater is difficult to separate because of the small droplet size and high interfacial stability of emulsified droplets. Herein, a series of porous poly(ionic liquid)s (PILs) with tunable wettability and pore structures were synthesized through Friedel-Crafts crosslinking reactions using cyanuric chloride and imidazole-derived ionic liquid monomers. By regulating the co-crosslinkers and crosslinkers, the surface wettability and porous architectures of the PILs were effectively tailored. The obtained materials exhibited either hydrophobic and oleophilic properties or hydrophilic and underwater oleophobic properties, enabling the selective separation of stratified oil-water mixtures and emulsified oil-water systems. For emulsified oil-water systems, the separation efficiencies exceeded 97%, with a maximum flux of 940 L·m −2 ·h −1 , while separation efficiencies above 99% and a maximum flux of 9251 L·m −2 ·h −1 were achieved for stratified oil-water mixtures. The results indicate that the co-crosslinkers primarily regulate surface wettability, whereas the rigid crosslinker promotes the formation of larger pore volumes and more efficient transport pathways, thereby enhancing permeation performance. This work establishes a structure-property relationship between co-crosslinker chemistry, pore architecture, and separation performance, providing a new strategy for the rational design of porous PIL-based oil-water separation materials.

Graphene oxide enhanced hydrogel enables tunable mechanics. • Sustained Rh1 release promotes angiogenesis via VEGF/CD31 upregulation. • Hydrogel boosts anti-inflammatory cytokines (IL-4, IL-10) for faster healing. • The water gel dressing has an antibacterial rate of up to 98.69% against S. aureus . During the healing process of skin wounds, there are challenges such as slow tissue regeneration and bacterial infections. This paper has developed a drug-loaded composite hydrogel dressing that can promote angiogenesis, inhibit bacteria, and reduce inflammation. The hydrogel is composed of gelatin (Gel) and acrylamide (AM), and is formed into a biomimetic cell membrane structure through cross-linking. By adding different concentrations of graphene oxide (GO), the tensile strength of the hydrogel dressing can be significantly increased (from 57.54 KPa to 95 KPa), and the adhesion strength (shear strength) can be effectively enhanced (16.44 KPa). Additionally, Panax ginsenoside Rh1 has been successfully encapsulated in the hydrogel, achieving local controlled release. In vivo evaluation shows that the enhanced matrix by graphene oxide and the sustained release of Panax ginsenoside Rh1 have an antibacterial rate of up to 98.69% against S. aureus . It also stimulates the proliferation, migration, and tube formation of endothelial cells, thereby achieving strong vascularization at the wound site. Moreover, it can enhance the secretion capacity of anti-inflammatory factors (IL-4 from 19.54 to 105.61 pg/mL, IL-10 from 151.94 to 339.98 pg/mL), thereby accelerating the wound healing process. This hydrogel dressing provides a promising strategy for achieving high-quality wound repair. Download: Download high-res image (223KB) Download: Download full-size image
