Photocatalytic hydrogen peroxide (H 2 O 2 ) synthesis in pure water (H 2 O) is challenging because it requires simultaneous efficient charge separation and selective two-electron oxygen reduction. Herein, we report an S-scheme Mn 0.2 Cd 0.8 S/ZnIn 2 S 4 (MZ) heterojunction that synergistically regulates interfacial charge flow and surface oxygen (O 2 ) adsorption configuration. The optimized MZ-15 achieves a H 2 O 2 production rate of 3917.3 μmol g −1 h −1 in pure water without sacrificial agents. The S-scheme pathway promotes charge separation while preserving strong redox capability. More importantly, the pronounced ionic-radius mismatch between Mn 2+ and Cd 2+ in Mn 0.2 Cd 0.8 S induces an asymmetric electronic environment that shifts O 2 adsorption from side-on to end-on (Pauling-type) configuration, thereby favoring O O bond retention and two-electron oxygen reduction reaction (2e − ORR). This work highlights that simultaneous engineering of interfacial charge dynamics and O 2 adsorption geometry is a powerful strategy for highly selective photocatalytic H 2 O 2 production An S-scheme Mn 0.2 Cd 0.8 S/ZnIn 2 S 4 heterojunction achieves coupled interfacial charge-flow engineering and Pauling-type O 2 adsorption to realize selective 2e⁻ ORR for H 2 O 2 production in sacrificial‑agent‑free pure water.

HAMA-EG hydrogel achieved ultra-rapid crosslinking and curing in 1 s under UV light • EG annealing enhanced compressive strength and mechanical durability of the hydrogel • HAMA-EG retained 72.52% cyclic mechanical retention after −20 °C freezing • HAMA-EG had wide-temperature stability, high water retention, and good cushioning • HAMA-EG hydrogel effectively mitigated vibration and drop damage on peach fruit Hydrogels are promising cushioning materials for fresh produce packaging because of their viscoelasticity, deformability, and energy-dissipation capability. In this study, a UV-curable hydrogel based on methacrylated hyaluronic acid (HAMA) was developed. Through ethylene glycol (EG) annealing, a cushioning material (HAMA-EG) with good low-temperature tolerance and high water retention was fabricated. Systematic characterizations indicated that the hydrogel achieved rapid 1 s UV curing, attributed to approximately 0.69 methacryloyl groups grafted per HA disaccharide unit, which provided sufficient photosensitive crosslinking sites on the HAMA chains. HAMA-EG also exhibited a regular porous structure, good mechanical properties (Young's modulus of 0.28 MPa and compressive strength of 3.85 MPa), and biocompatibility. The incorporation of EG enhanced the material's low-temperature resistance (no freezing at −40 °C) and environmental stability (cumulative weight loss of only 29.41% after 120 h). In addition, HAMA-EG Gel showed enhanced cyclic mechanical stability after environmental pretreatment; after −20 °C freezing, its cyclic mechanical retention remained at 72.52%, compared with 6.43% for HAMA Gel. In simulated vibration and drop transportation tests using peaches as a bruise-sensitive fruit model, HAMA-EG reduced mechanical damage and better maintained fruit quality than commercial cushioning materials. Overall, HAMA-EG enabled rapid curing and forming with good energy dissipation and water-retention properties, thus holding broad application in cushioning protection for fresh produce.

An all-organic S-scheme NV-CN-PDI 5.0 heterojunction was successfully fabricated. • The improved yield can be attributed to the synergistic effect of nitrogen vacancies and the S-scheme heterojunction. • The CO yield of NV-CN-PDI 5.0 reached 37.06 μmol g −1 h −1 , 5.5 times that of pristine CN. • Photocatalytic mechanism is elucidated by experiments and calculations. Developing high-efficiency carbon nitride (CN) based photocatalysts is central to sunlight-powered CO 2 photoreduction, yet real-world application is constrained by severe bulk charge recombination and large interfacial transport barriers at heterojunction boundaries. Against this backdrop, we report an all-organic covalently bonded S-scheme heterojunction photocatalyst that resolves these limitations via the synergy of nitrogen-vacancy engineering and built-in electric-field (IEF) modulation. Highly crystalline perylene diimide (PDI) is covalently coupled with nitrogen-deficient carbon nitride (N V -CN) through interfacial C N linkages to form an intimate heterointerface. Benefiting from the combined effect of interfacially generated IEF and in-situ introduced nitrogen vacancies, photogenerated electrons are efficiently trapped and carriers are steered along directional migration pathways, markedly suppressing electron–hole recombination and diminishing interfacial charge-transport resistance. Experimental evaluations confirm that the optimized N V -CN-PDI 5.0 catalyst delivers exceptional CO 2 photoreduction performance with a CO production rate of 37.86 ± 1.04 μmol g −1 h −1 , far exceeding pristine CN and its physically blended counterparts. Supported by density functional theory (DFT) calculations, the synergistic enhancement originating from defective sites and S-scheme charge-transfer dynamics is systematically elucidated. This work affords an instructive route toward the rational design of high-performance all-organic S-scheme heterojunction photocatalysts. By bridging N V -CN with PDI, a covalently bonded S-scheme N V -CN-PDI 5.0 heterojunction is constructed. The internal built-in electric field and C − N covalent bonds synergistically serve as charge transport pathways to accelerate charge migration and separation, thereby distinctly boosting the photocatalytic CO 2 reduction performance.

Industrial wastewater causes serious water pollution, so it is urgent to remove toxic dyes like malachite green (MG). In this study, a 0D/2D S-scheme heterojunction was constructed by anchoring CeO 2 nanocubes onto SnSe 2 hexagonal nanosheets via a precisely controlled two-step hydrothermal strategy. In-situ electron paramagnetic resonance (EPR) analysis corroborates that illumination triggers the proliferation of surface oxygen vacancies. These photo-induced oxygen vacancies (OVs, oxygen vacancies) empower the CeO 2 /SnSe 2 heterostructure to sustain exceptional catalytic activity over five consecutive cycles. Moreover, the optimized 0.2 g CeO 2 /SnSe 2 composite exhibits a remarkable degradation efficiency of 100% for MG within 30 min. Such performance enhancement is attributed to the synergy between the 0D/2D dimensional matching and a potent internal electric field (IEF), which triggers an S-scheme charge transfer mechanism to preserve high redox potential while accelerating carrier separation. This work provides a sophisticated blueprint for designing dimension-matched S-scheme heterojunctions for high-performance environmental remediation.

Background: Indole-3-propionic acid (IPA) is a tryptophan metabolite produced by intestinal bacteria, which has functions such as penetrating tissue barriers and reducing tissue inflammatory reactions. In the present study, the therapeutic effect of IPA on Staphylococcus aureus (S. aureus)-induced mastitis was investigated.Methods: A mouse model of mastitis was established using breast injection of S. aureus. Except for the control group, all other mice were given oral administration of IPA. Hematoxylin eosin (H&E) staining was used to detect pathological changes in mouse mammary tissue. ELISA was used to detect TNF-α and IL-1β levels. Western blot was used to detect protein expression.Results: As the results demonstrated, IPA treatment obviously attenuated S. aureus-induced mammary pathological injury, myeloperoxidase (MPO) activity, malondialdehyde (MDA) content, TNF-α, and IL-1β levels. Meanwhile, IPA treatment could restore blood-milk barrier, as confirmed by up-regulating the expression of ZO-1 and occludin. In vitro, IPA could inhibit TNF-α and IL-1β production and the activation of NF-κB and NLRP3 induced by S. aureus. Furthermore, IPA could increase the expression of aryl hydrocarbon receptor (AhR). In addition, the inhibition of IPA on S. aureus-induced inflammation was reversed by AhR inhibitor.Conclusion: In conclusion, the results suggested that IPA inhibited S. aureus-induced mastitis through inhibition inflammation and restoring blood-milk barrier by activating AhR.

This study constructed an S-scheme MIL( Fe )DCA (et al., 2023b (6)) /MoS 2 heterojunction for enhanced performance in degrading pollutants under a wide spectrum, benefiting from the customized d-band centers (by the built-in electric field) and the Mars–Van Krevelen cycle. Results reveal the tetracycline degradation rate of MIL( Fe )DCA (et al., 2023b (6)) /MoS₂ (~95 %) increases 1.38-fold and 11.8-fold compared to pristine MIL-Fe-DCA and MoS 2 , respectively, with better repeatability.Also, satisfactory reduction of Cr(VI) ions (75 %) and removal of coumarin (81.3 %) and ciprofloxacin hydrochloride (83 %) are observed. The catalyst exhibits rich defects, wide-spectrum solar light harvesting, efficient separation of h + ~ e − pairs and a robust redox process. It is found that the charge transfer in the S-scheme interfacial electric field elevates the d-band center towards the Fermi level, which can effectively lower water activation energy to more easily produce •OH, enhancing intermediate adsorption on the catalyst's surface, thus facilitating charge transfer and accelerating reaction kinetics. Another major emphasis is the oxygen defects induced Mars–Van Krevelen cycle, wherein adsorbed reactants, lattice oxygen, h + , •O 2 − , Fe 2+ and Fe 3+ participate in the reaction processes, which contributes to the photo-thermal conversion, achieving the synergy between photocatalysis and photothermal catalysis. This work offers a synergetic strategy involving the interfacial electric field, d-band center, and photo-thermal effect for photocatalytic water purification.

Intensified electrochemical corrosion under high-temperature and phosphoric acid conditions poses a significant challenge to the catalysts in high-temperature proton exchange membrane fuel cells (HT-PEMFCs). Herein, a S, P-doped hierarchical porous carbon nitride (S, P-HCN) supported PtCo alloy catalyst was developed to address this issue. The multilayered porous structure of S, P-HCN ensures high metal dispersion, a large specific surface area, and enhanced mass transfer. The PtCo/S, P-HCN catalyst exhibits remarkable performance, with specific activity (1.27 mA cm Pt -2 at 0.80 V), mass activity (0.51 mA µg Pt -1 at 0.80 V), and electrochemical active surface area (ECSA) (39.9 m 2 g -1 Pt ), surpassing commercial 20 % Pt/C by 2–3 times. Durability tests over 5000 potential cycles reveal excellent retention of mass activity (84 %) and specific activity (83.2 %) at 0.80 V, with only a minor 14 mV shift in half-wave potential. This enhancement stems from the synergistic effects between PtCo alloy nanoparticles and S, P-HCN, which modulate Pt- electronic structure, strengthen metal-support interactions, and boost catalytic efficiency. Single-cell HT-PEMFC studies demonstrate a peak power density of 377.4 mW cm −2 for PtCo/S, P-HCN, comparable to commercial Pt/C (398 mW cm −2 ), with reduced voltage degradation at low current densities. This work presents a promising approach for improving cathode materials and advancing HT-PEMFC performance.

Colorimetric/surface-enhanced Raman scattering (SERS) dual-mode detection offers richer detection information and higher accuracy. However, achieving “non-enzymatic” one-step catalytic colorimetric/SERS glucose detection using molybdenum disulfide (MoS 2 )-based nanozymes remains challenging. Here, we propose a tandem enzyme system, BAMC, composed of bovine serum albumin-modified gold nanoparticles (BSA@Au) integrated with carboxylated molybdenum disulfide (MoS 2 –COOH). This approach overcomes the inhibition of glucose oxidase (GOx)-like activity caused by Au–S bonding, enabling dual-mode colorimetric/SERS glucose detection with detection limits (LOD) of 10 −6 M and 10 −7 M, respectively. For non-invasive glucose detection, the BAMC system demonstrated excellent stability in saliva and urine samples. The results were highly consistent with commercial glucose detection methods, with errors controlled at 19.67 % and 6.66 %, meeting the World Health Organization ’s standard of less than 20 % error for glucometers. The BAMC system offers a novel approach for non-invasive glucose detection and paves the way for developing other nanozymes.

Designing a highly sensitive electrochemical sensing interface and elucidating the mechanism of enhanced electrochemical signals from the perspective of electronic structure are crucial for accurate detection of heavy metal ions (HIMIs). In this study, a composite transition metal sulfide Co 9 S 8 @MoS 2 heterostructure was developed for the high-sensitivity detection of Pb(II) in Chinese herbal medicine, which achieved a high sensitivity of 103.3 ± 0.5 μA μM −1 and a detection limit of 0.01 μM. Moreover, the fundamental reason for the excellent detection of Pb(II) was investigated by X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT). The results indicated that the recombination of the heterojunction not only catalyzes the activation of the Co site in Co 9 S 8 but also promotes S as a medium in the electron channel for increased charge transfer. In addition, the proposed method displayed anti-interference ability with outstanding stability and reproducibility in the presence of other HMIs. Importantly, the highly sensitive detection of Pb(II) has also been inherited in herbal Rehmannia glutinosa samples, demonstrating its potential for practical application in the detection of heavy metal ions in Chinese herbal medicine. This work provides essential theoretical guidance for constructing high-performance electrochemically sensitive interfaces from electronic structure-controlled sensing materials.

The widespread deployment of renewable energy sources worldwide, such as wind power and photovoltaics, has created an urgent need for efficient energy storage systems. Biomass-derived carbon aerogels, due to their environmentally friendly and sustainable properties, have emerged as ideal precursor materials for advanced energy storage applications, particularly in supercapacitors. This study developed a method to prepare phytate-induced phosphorus/sulfur (P/S) co-doped magnesium lignosulfonate-based carbon aerogels (LCAs). Phytate induction facilitated the formation of regular spherical structures while simultaneously optimizing surface morphology and enabling efficient and uniform doping of P and S heteroatoms. The optimized sample, LCA-2-700, the lignin-based carbon aerogel that was prepared with the magnesium lignosulfonate (LS)꞉sodium alginate (SA)꞉phytic acid (PA) mass ratio of 5꞉5꞉2 and carbonized at 700 °C, exhibited a specific capacitance of 362 F/g at the current density of 0.5 A/g, with the assembled device achieving an energy density of 40.1 W·h/kg at a power density of 700 W/kg. After 20 000 cycles, the capacitance retention rate remained at 82.5%, demonstrating excellent electrochemical durability. The high performance was attributed to the synergistic effects of its spherical structure, high specific surface area, and P/S dual-heteroatom doping. This study provides an effective approach for synergistic structure-doping regulation of lignin-based carbon aerogels and provides a potential pathway for practical applications in high-performance supercapacitors.

The conversion of lignin into high-value-added materials not only helps alleviate the energy crisis but also provides an efficient waste management solution. In this study, we present a simple extraction method of organosolv lignin from rice husks and demonstrate its application as a precursor for synthesising nitrogen and sulphur co-doped carbon quantum dots (N,S-LCQDs). The prepared N,S-LCQDs exhibited strong blue fluorescence with excellent photostability and were successfully employed as a selective fluorescent sensor for Fe3+ ions in aqueous solutions. Spectroscopic analysis revealed that the N,S-LCQDs displayed excitation-dependent emission behaviour with a quantum yield of approximately 9.7%. The fluorescence intensity of N,S-LCQDs decreased progressively with increasing Fe3+ concentration, exhibiting a good linear relationship over the range of 0–100 μM and a detection limit of 0.91 μM. The sensing mechanism was thoroughly investigated using Stern-Volmer analysis at different temperatures and fluorescence lifetime measurements. This work not only provides a sustainable approach for valorising rice husk biomass but also develops a cost-effective, sensitive, and selective fluorescent probe for Fe3+ detection in environmental and biological samples.
