Dual-phase gelation in W/O/W emulsions enables robust, tunable probiotic delivery. • Oil-phase gelation using PGPR and wax reduces droplet size and raises viscosity. • Aqueous-phase gelation using CaCO₃-pectin/WPI network increases bound water. • Dual-phase gelation yields highest mechanical strength and probiotic survival. To overcome the poor stability and low probiotic survival associated with traditional delivery systems, this study systematically developed and compared water-in-oil-in-water (W/O/W) emulsions with different phase gelation strategies. Three emulsion types were constructed: oil-phase (O-W/O/W), external aqueous-phase (A-W/O/W), and dual-phase gelled (B-W/O/W) emulsions. The results revealed that dual-phase gelation (B-W/O/W) exhibited a superior synergistic effect compared to single-phase gelation. Both aqueous- and oil-phase gelation increased apparent viscosity and restricted internal water mobility, but their combination provided the most robust physical barrier. Specifically, oil-phase gelation reduced particle size by immobilizing free water, while aqueous gelation formed a dense protective network. This synergistic protection significantly enhanced probiotic viability during pasteurization, in vitro digestion, and long-term storage. This study demonstrates that dual-phase gelation is a highly effective and novel strategy for the development of high-performance delivery vehicles, providing a theoretical basis for the commercial application of sensitive probiotics in functional foods.

Tartaric acid creates cooperative S O coordination sites on MoS 2. • Sugarcane bagasse biochar confines and disperses MoS 2 nanosheets. • Spatial confinement accelerates Pb 2+ transport and interfacial enrichment. • DFT confirms strong Pb 2+ binding at S O dual sites with −5.24 eV. Lead (Pb 2+ ) pollution in industrial wastewater poses severe threats to human nervous system and ecological security due to its high toxicity, bioaccumulation and non-biodegradability. Although MoS 2 nanosheets exhibit excellent affinity for Pb 2+ , their adsorption performance is constrained by nanosheet stacking and limited accessible active site separation performance. Herein, tartaric acid (TA)-functionalized MoS 2 nanosheets were confined within a sugarcane bagasse-derived biochar (BC) scaffold to construct TA-MoS 2 /BC. The porous carbon framework suppresses MoS 2 nanosheet restacking and creates accessible mesoporous channels for Pb 2+ transport, while TA introduces oxygen-containing groups that cooperate with sulfur sites for strong Pb 2+ binding. TA-MoS 2 /BC exhibited a high Langmuir adsorption capacity of 1073.27 mg·g −1 , together with a kinetic adsorption capacity of 726.60 mg·g −1 , which was 1.47 and 2.44 times higher than pure TA-MoS 2 and raw biochar, respectively. After five adsorption-desorption cycles, the composite retained 77.8% of its initial adsorption capacity, demonstrating satisfactory reusability. XPS and DFT analyses confirmed that adjacent S/O dual sites dominated Pb 2+ capture, showing a low adsorption energy of −5.24 eV and charge transfer of 1.068 e. Intraparticle diffusion analysis revealed a multi-stage mass-transfer process, and TA-MoS 2 /BC showed the highest initial diffusion rate constant of 48.25 mg·g −1 ·h -1/2 , confirming that the confined porous structure promoted Pb 2+ migration toward internal active sites. This work provides a confinement-coordination dual-regulation strategy for Pb 2+ removal while offering a value-added route for converting sugarcane bagasse waste into a functional carbon scaffold.

Immune checkpoint blockade (ICB) therapy faces major challenges including low clinical response rates, while traditional chemodynamic therapy (CDT) is highly dependent on intratumoral hydrogen peroxide (H₂O₂) levels. To address these limitations, we constructed a pH-responsive hyaluronic acid (HA)-based nanosystem (HA-Fc@ART) for targeted cancer therapy. This nanoplatform achieves tumor-specific delivery through the specific interaction between HA and CD44 receptors overexpressed on tumor cells. Upon accumulation in the acidic tumor microenvironment (TME), the nanosystem undergoes Schiff base bond hydrolysis to precisely release artemisinin (ART) and ferrocene (Fc), avoiding off-target toxicity. Fc catalyzes the cleavage of the endoperoxide bridge in ART to generate singlet oxygen ( 1 O₂) in an H₂O₂-independent manner. It simultaneously converts endogenous H₂O₂ into hydroxyl radicals (•OH) via the Fenton reaction. These dual pathways synergistically induce a reactive oxygen species (ROS) burst that efficiently eliminates cancer cells. Notably, HA-Fc@ART exhibits a high photothermal conversion efficiency of 35 ± 3%. The photothermal effect accelerates ROS production, and Fe(III) generated during the reaction depletes intracellular glutathione (GSH) to amplify oxidative damage. In vitro and in vivo experiments demonstrated that HA-Fc@ART possesses strong tumor-targeting ability. It effectively induces tumor immunogenic cell death (ICD) by releasing damage-associated molecular patterns (DAMPs). This process activates dendritic cell (DC) maturation, promotes macrophage M1 polarization, and enhances T cell infiltration into the TME. In the 4 T1 bilateral tumor model, the combination of HA-Fc@ART with photothermal therapy and anti-PD-L1 (αPD-L1) achieved complete ablation of primary tumors and significant inhibition of distant metastatic tumors. Histological analysis and hemolysis tests confirmed the nanosystem's excellent biosafety profile. This study provides a novel and efficient platform for improving the response rate of ICB therapy, offering new insights into the treatment of metastatic cancers.

The high interfacial charge transfer barrier has been a primary thermodynamic obstacle in enhancing the catalytic performance of heterojunction materials. Optimizing the interfacial environment is a promising strategy to attain superior catalytic efficiency. Hence, a Bi/Bi2MoO6/Bi24O31Br10 (Bi/BMO/BOB) composite photocatalyst was constructed by introducing a Bi–O–Mo bridge bond between the BMO and BOB interfaces and modifying metal active sites on the surface of the complex. Bi/BMO/BOB has a good capacity for CO2 photoreduction to CO. The CO yield of the Bi/BMO/BOB photocatalyst is 68.29 μmol g−1 h−1, which is obviously higher than those of the pristine BMO and BOB. As proved by density functional theory (DFT) calculations and experimental characterization, the Bi–O–Mo interface bridge bond adjusts the electronic structure of the contact interface and enhances the interface charge separation and transport rate. Moreover, the metal Bi nanoparticles synthesized through in situ reduction not only realize electron transfer and storage as electron collectors, but also strengthen the adsorption of CO2 molecules. The synergistic action of the two can allow the effective transfer of photogenerated electrons from BMO to BOB, which then accumulate on Bi. Such stepwise transfer of electrons increases the speed of photocatalytic reduction processes that involve multiple electrons, and effectively reduces the reaction energy barrier in the process of CO2 reduction. This mode of interatomic electron transfer bridges combined with the metal active sites not only solves the stability issues in bismuth-based semiconductors, but also aids in the development of more efficient photocatalytic systems for reduction of CO2.

Carbon monoxide (CO) can rapidly accumulate in confined environments such as tunnel fires, posing an acute poisoning risk and demanding catalysts with low-temperature light-off and fast purification capability. Here, we construct a porous mixed-oxide framework from a Ce–Co metal–organic framework precursor and subsequently load 7 wt% CuO, yielding CuO@Co x Ce 1−x –O composite catalysts. Tricobalt tetraoxide (Co 3 O 4 ), Cerium dioxide (CeO 2 ) and Copper (II) oxide (CuO) are deliberately selected to couple reversible oxygen storage/defect regulation (Ce 4+ /Ce 3+ ), low-temperature redox cycling (Co 3+ /Co 2+ ), and interfacial charge-transfer sites for CO activation (CuO). Meanwhile, the MOF-derived strategy enables homogeneous component dispersion, abundant porosity, and intimate heterointerfaces, thereby maximizing interfacial synergy. Among the series, CuO@ Co 8 Ce 2 –O (Co:Ce = 8:2) exhibits the best performance, decreasing the temperature required for 90% CO conversion by 216 °C relative to the undoped counterpart and maintaining stable activity during prolonged operation. Correlating micromorphology, surface physicochemical properties, and redox/oxygen-mobility behavior reveals that moderate Ce incorporation increases defect-associated reactive oxygen species and accelerates oxygen transport, while strengthened Ce–Co electronic coupling further promotes interfacial synergy at the CuO–oxide junctions. Mechanistic evidence supports a Mars–van Krevelen pathway with dynamically regenerated interfacial oxygen vacancies, enabling rapid CO oxidation. This work provides a rational interface-engineering strategy for efficient CO purification in confined fire-related scenarios.

To improve the photocatalytic performance of g-C 3 N 4 (CN), mechanical activation (MA) treatment of precursor followed by calcination was developed to construct a N−Mo−O bond bridged MoO 2 /Mo-doped CN (MA-MoO 2 /Mo-CN) Schottky heterojunction composite, which was used as a visible light-driven photocatalyst for degrading tetracycline (TC). The as-prepared MA-MoO 2 /Mo-CN with strong interfacial interaction showed excellent photocatalytic performance and structural stability, with 92.3% of TC degradation efficiency within 90 min and maintaining over 90% of degradation efficiency after five consecutive cycles. The enhanced photocatalytic performance can be ascribed to that MA treatment induced the improvement of surface area and the formation of N vacancies and N−Mo−O bonds, which served as a bridge to connect Mo-CN and MoO 2 for constructing a Schottky barrier. These provided more reactive sites and effectively enhanced migration efficiency of interface electrons, separation efficiency of photogenerated carriers, and light absorption capacity. In addition, the mechanism of photocatalytic degradation of TC and its possible degradation pathway were investigated. This research provides an environmentally friendly and feasible method for producing highly active precious metal-free photocatalysts with excellent migration and separation efficiency of photoexcited charge carriers.

Eggs are nutritious and highly valued by consumers. However, egg flavor varies greatly among different hen breeds. The present study used gas chromatography-olfactometry-mass spectrometry-based volatilomics to identify and compare volatile compounds in Taihe black-boned silky fowl (TS) and Hy-line Brown (HL) egg yolks. In addition, the relationships between the levels of different metabolites and lipids and flavor-associated differences were investigated using multiomics. Twenty-eight odorants in total were identified; among them, the levels of 3-methyl-butanal, 1-octen-3-ol, 2-pentylfuran, and (E, E)-2,4-decadienal differed significantly ( P < 0.05) between TS and HL egg yolks. The difference in flavor compounds results in TS egg yolks having a stronger overall odor and flavor and a higher acceptance level than HL egg yolks. Metabolomic analysis revealed that 112 metabolites in the egg yolks were significantly different between the two breeds. Furthermore, these different metabolites in the egg yolks of both breeds were significantly enriched in phenylalanine , tyrosine , and tryptophan biosynthesis pathways and phenylalanine metabolism, alanine , aspartate, and glutamate metabolism pathways ( P < 0.05), as identified by both metabolite set enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses. Lipidomic analysis revealed significant differences in the lipid subclasses, lipid molecules, and fatty acid profiles between the egg yolks from the two breeds. As a result, 48 lipid molecules had variable influence in projection values > 1 based on the partial least squares regression model, which may play a role in the differences in aroma characteristics between the two breeds through oxidative degradation of fatty acids. Our study revealed the metabolite, lipid, and volatility profiles of TS and HL egg yolks and may provide an important basis for improving egg flavor to satisfy various consumer preferences.

Water-soluble captopril-capped atomically precise Pd nanoclusters (Pd17Capt8 NCs: 1.3 ± 0.5 nm) produced by a simple chemical reduction were supported on preprepared hybrid Co3Al-layered double hydroxide/reduced graphene oxide (Co3Al-LDH/rGO) by a pH-adjusted electrostatic adsorption strategy followed by proper calcinations, giving a series of novel catalysts x-PdNCs/CoAl(O)/rGO-T (x (Pd loading) = 0.09, 0.17, 0.43 wt % (ICP), T = 230, 250, 280, 300, 320 °C). The characterization results show that the as-obtained catalysts possess the hierarchical nanosheet array morphology. Pd NCs with a size of ∼1.3 to 1.8 nm are highly distributed at the edge sites of the CoAl(O) nanosheets. All of the x-PdNCs/CoAl(O)/rGO-T catalysts show superior catalytic efficiency for the conversion of 4-nitrophenol to 4-aminophenol, particularly 0.17-PdNCs/CoAl(O)/rGO-300 possesses the highest performance with a turnover frequency (TOF) of 30 042 h–1, which is the highest among the reported Pd-based catalysts so far. The superior activity of 0.17-PdNCs/CoAl(O)/rGO-300 can be owing to ultrafine Pd NCs with a clean surface, the strongest PdNCs–Co2+-OH(LDH)–rGO three-phase synergy, and the much improved adsorption of the substrate via π–π stacking upon nanosheet array morphology. Meanwhile, 0.17-PdNCs/CoAl(O)/rGO-300 exhibits excellent catalytic activities for various nitroarenes and anionic azo dyes as well as good reusability with the complete reduction of 4-nitrophenol (4-NP) within 90 s after 10 successive runs. The present work provides not only a simple and convenient strategy for the synthesis of clean, efficient, and environmentally friendly supported metal nanocluster catalysts but also a new idea for the efficient catalytic degradation of environmental pollutants.

A new composite of o-aminobenzene sulfonic acid self-doped polyaniline (SPAN) and multi-walled carbon nanotubes was prepared on a stainless steel wire by electrochemical method as a headspace solid-phase microextraction fiber for gas chromatography. Preparation conditions were investigated, and the resulting composite coating was characterized via scanning electron microscopy, Brunauer–Emmett–Teller (BET) analysis and thermogravimetric analysis. Introduction of MWCNTs and o-aminobenzene sulfonic acid into the composite leads to formation of plenty of microglobules and mesopores and makes BET surface area and thermal decomposition temperature of the composite increase by ~ 340% and ~ 130 ℃, respectively, compared to common polyaniline coating. Extraction conditions were optimized, and chromatographic analysis of 2,4-dichlorophenol was conducted. Extraction efficiency of the new composite coated fiber increases by 320% compared to polyaniline-coated fiber. Relative standard deviations of peak areas are 4.3%, 6.3%, 7.1% ( n = 5) for identical fiber, fibers prepared in identical batch and different batches, respectively, exhibiting good repeatability and reproducibility. Detection limit is 1.30 ng L −1 (S/N = 3), and recoveries are in the ranges from 82.3 to 110.2%, from 91.5 to 109.4% and from 94.2 to 113.0% for three different water samples spiked at three levels of 500, 100 and 10 ng mL −1 , respectively.

Photocatalytic technique has been widely accepted as a promising and effective candidate for eliminating antibiotic and pathogen pollutants in aquatic environment. Herein, a novel O, K co-doped g-C 3 N 4 photocatalyst embedded with single-atom Ag (denoted as Ag/OKCN) was successfully constructed to achieve the enhanced photocatalytic degradation and disinfection efficiency under visible light irradiation. The optimal Ag/OKCN-6 could eliminate 80.4 % of tetracycline (TC) within 60 min with a rate constant of 0.0259 min −1 , which was 4.98 times of pristine g-C 3 N 4 . Meanwhile, Ag/OKCN-6 could also completely inactivate>7-log CFU·mL −1 of Escherichia coli ( E. coli ) by efficient disruption of cell membranes. The synergistic effect of O, K co-doping and single-atom Ag embedding contributed to an extended light response, preeminent separation and transfer of photoexcited charges, prolonged carrier lifetime as well as ameliorative hydrophilicity, which was conducive to the excellent photocatalytic performance. Radical trapping and electron spin resonance (ESR) experiments validated that superoxide radicals ( • O 2 − ) were crucially responsible for the superior photocatalytic activity. This work provides a facile route to construct multi-strategy modified g-C 3 N 4 -related photocatalysts for efficiently eliminating aquatic environmental pollutants.

The requirements of the morphology and material properties in common make it possible to integrate the two functional electrodes, hydrogen electrocatalyst and supercapacitor , into one material system. The order of electrochemical performance of core materials was ranked as NiCoP > NiCo 2 S 4 > NiCo 2 O 4 . By constructing core/shell heterostructure, Ni-Co-X/Co(OH) 2 composites achieved the boost of electrochemical performance than individual Ni-Co-X. Particularly, the NiCoP/Co(OH) 2 composite synthesized under optimal conditions presented both excellent catalytic activity and charge storage capability. The NiCoP/Co(OH) 2 composite needed small overpotential of 73 mV to drive current density of 10 mA cm −2 in 1 M KOH, displayed Tafel slope of 75 mV dec −1 and long-term stability over 15 h without obvious fluctuation. Moreover, the NiCoP/Co(OH) 2 composite showed high specific capacitance of 1604 F g −1 at 1 A g −1 , delivered remarkable rate capability of 81.8 % at 20 A g −1 and cyclic stability with 91.8 % capacity retention over 5000 cycles. The impressive electrochemical properties of NiCoP/Co(OH) 2 composite is attributed to the enriched active sites, enhanced electronic conductivity and strong synergistic effect.

The postharvest senescence accompanied by yellowing limited the shelf-life of broccoli. In this study, we developed a novel W/O/W double emulsion co-delivering brassinolide and cinnamon essential oil and applied it to broccoli for preservation. Results showed that double emulsion prepared by whey protein concentrate-high methoxyl pectin (1:3) exhibited best storage stability with largest particle size (581.30 nm), lowest PDI (0.23) and zeta potential (−40.31 mV). This double emulsion also exhibited highest encapsulation efficiency of brassinolide (92%) and cinnamon essential oil (88%). The broccoli coated with double emulsion maintained higher chlorophyll contents and activities of chlorophyllase and magnesium-dechelatase were reduced by 9% and 24%, respectively. The energy metabolic enzymes (SDH, CCO, H + -ATPase, Ca 2+ -ATPase) were also activated, inducing higher level of ATP and energy charge. These results demonstrated W/O/W double emulsion co-delivering brassinolide and cinnamon essential delayed the senescence of broccoli via regulating chlorophyll degradation and energy metabolism.
