Alcoholic liver disease (ALD) is one of the most prevalent liver diseases worldwide. There are currently no FDA approved pharmacological therapies specifically designed to prevent or treat ALD. Targeted nutritional interventions offer a promising avenue for ALD management. Cyanidin-3-O-glucoside (C3G), a natural anthocyanin, has shown potential in mitigating alcoholic liver injury, but its therapeutic utility is limited by poor stability and inadequate liver targeting. Here, we report a galactosylated chitosan-modified nanoplatform for the encapsulation and hepatic targeted delivery of C3G. The fabricated nanonutriosomes (C3G@GC-NS) exhibited favorable physicochemical stability, biosafety, and enhanced C3G accumulation in the liver. In a mice model of alcoholic liver injury induced by 15-day ethanol feeding, oral administration of C3G@GC-NS at a dose of 150 mg /kg (C3G equivalent) daily significantly alleviated liver injury. C3G@GC-NS outperformed free C3G in ameliorating steatosis, inflammation, and metabolic dysfunction. Mechanistically, the nanotherapeutic activates the AMPK signaling pathway, regulates PPARα-driven lipid and ethanol metabolism, and restores alcohol-induced gut microbiota dysbiosis. This study presents a rationally designed nanoplatform that enhances the therapeutic efficacy of C3G through coordinated modulation of hepatic metabolism and the gut-liver axis, offering a novel strategy for the treatment of ALD.

In response to water scarcity and energy crises, solar-driven interfacial evaporation technology offers a highly promising industrial solution for seawater desalination due to its “zero energy consumption” and environmentally friendly characteristics. The aromatic ring structure of lignin exhibits excellent light absorption properties, making it a highly suitable material for interfacial evaporation photothermal applications. This study employs electrospun lignin nanofiber membranes that have undergone high-temperature carbonization, with Fe₃O₄ nanoparticles in situ loaded onto their surfaces to form a photothermal layer. Polyvinylidene fluoride (PVDF) serves as both a binder and hydrophobic modifier, bonding at the interface with delignified wood blocks (DW). Based on this design, the fabricated LCNFs/Fe₃O₄@DW evaporator achieves an evaporation rate of 1.76 kg·m −2 ·h −1 under one standard solar irradiance, with an evaporation efficiency of approximately 88.54%, outperforming most conventional wood-based or carbon-based photothermal evaporators. Long-term cycling tests and simulated seawater evaporation experiments demonstrate the material's excellent salt resistance and purification durability. In summary, this study not only validates the application potential of lignin-based nanofiber composites in solar thermal conversion but also achieves functional integration of “solar desalination, salt resistance and scale prevention, and water purification” through precise Janus surface design. It provides a novel strategy that combines environmental sustainability with practical applicability for industrializing solar-driven interfacial evaporation technology.

As a key intermediate in the synthesis of anticancer agents, 5′-O-Dimethoxytrityl-N-benzoyl-deoxycytidine (Bz-Dmt-dC) usually presents as a solvate and its purity plays a critical role in the production process. To obtain high purity products quickly and efficiently via crystallization, the solubility data of the compound must first be determined. Therefore, under the premise of ensuring no phase transitions during the measurement process, the solubility of solvates formed by Bz-Dmt-dC in three binary solvent systems (acetonitrile + water, acetone + water, and THF + water) were experimentally determined over the temperature range of 278.15 to 313.15 K at atmospheric pressure using the gravimetric method. The experimental results showed that, for a given solvent type and composition, the solubility of Bz-Dmt-dC increased with increasing temperature. The solubility data of Bz-Dmt-dC were correlated using the modified Apelblat, λ h, and NRTL equations. Among these, the modified Apelblat model provided the best fitting result, as indicated by the lowest average relative deviation (ARD) values of 0.7%.

The amorphous structure of conducting polymers (CPs) has made it difficult for the researcher to get regular crystallike CP nanoparticles (such as: cube, triangle, polygon and polyhedron) without template. This paper brings forward a new idea for to get regular crystallike CP nanoparticles via the structure-directing role which can be attributed to the dipole and π–π interaction between oligomers . The regular hexagonal prism or equilateral triangle shapes PoPD nanoparticles can be easily prepared with our new way. The mechanism is proved by analyzing the morphology of precursor at the early stage of hydrothermal progress. We also explored the feasibility of using nano-sized PoPD hexagonal prisms for Cu 2+ supersensitive fluorescence detection. The ultra-sensitive of PoPD hexagonal prisms is remarkable.

Construct PtCu/CeO 2 heterojunction to resolve alkaline HER activity-stability trade-off dilemma. • Form strong Pt-O-Ce interfacial bonds to restrain Pt oxidation and metal leaching. • CeO 2 serves as efficient promoter to drastically accelerate water dissociation step of alkaline HER. • Assembled AEMWE cell delivers 2500 h ultra-long stability at industrial current density. The persistent activity-stability trade-off in electrocatalysts, driven by the dynamic evolution of active sites, severely limits the practical application of anion exchange membrane water electrolysis (AEMWE). Herein, we construct a robust PtCu/CeO 2 heterostructure that simultaneously achieves superior activity and long-term durability for alkaline hydrogen evolution reaction (HER). The catalyst exhibits an ultralow overpotential of 10 mV at 10 mA cm −2 and a small Tafel slope of 23.2 mV dec −1 , significantly outperforming conventional Pt/Ni(OH) 2 and Pt/C electrodes. In a full AEMWE cell, the PtCu/CeO 2 ||NiFe LDH system requires only 1.71 V to reach 1 A cm −2 and maintains stable operation for 2500 h with negligible decay, ranking it among the best-performing alkaline HER catalysts. Mechanistically, Cu alloying optimizes the hydrogen adsorption energy of Pt, while CeO 2 acts as an effective water dissociation promoter to accelerate the overall reaction kinetics. Moreover, strong Pt-O-Ce interfacial bonding between the thermodynamically stable CeO 2 and PtCu alloy, together with significant hybridization of Pt 5d/Cu 3d and Ce 4 f/O 2p orbitals, effectively suppresses the dissolution and oxidation of Pt sites. thereby enhancing the durability of the catalyst under high-current-density operation. This work offers a viable strategy to overcome the activity-stability dilemma in HER catalysts for industrial AEMWE.

Engineering interatomic orbital hybridization to mediate the dynamic coupling of interfacial charge transfer and surface oxygen evolution remains a challenge in boosting the photoelectrochemical (PEC) water oxidation performance. Herein, a three-dimensional nanoporous network heterostructure of BiVO 4 /LaCoO 3 is fabricated by decorating BiVO 4 with LaCoO 3 perovskite single-crystalline quantum dots (PSC QDs). The enhanced interfacial built-in electric field in band-matched BiVO 4 /LaCoO 3 sharpens band bending, providing the driving force for interfacial charge transfer. Experiments and theoretical calculations reveal that V(3 d )-O(2 p )-Co(3 d ) synergistic orbital hybridization at BiVO 4 /LaCoO 3 interface provides a low-barrier hopping pathway for electron transitions, strengthens Co-O covalency, and optimizes the Co d -band center position. Co–O antibonding/bonding states shifting toward the Fermi level and Co 3+ -O 2− -Co 4+ double exchange facilitate efficient electron-hole separation, which regulate the electronic structure for BiVO 4 /LaCoO 3 . The BiVO 4 /LaCoO 3 photoanode achieves an enhanced photocurrent density of 4.19 mA cm −2 (vs. 2.01 mA cm −2 for BiVO 4 at 1.23 V vs. RHE). Meanwhile, online electrochemical test presents that the LaCoO 3 coupling on BiVO 4 provides rich active sites for the oxygen evolution reaction (OER), promoting the hole relaxation dynamics. Bridge-mediated coupling of charge transfer and photocatalytic oxidation via V(3 d )-O(2 p )-Co(3 d ) synergistic orbital hybridization is kinetically favorable, thus synergistically improving the PEC performance for BiVO 4 /LaCoO 3 . This work offers a valuable insight into the mechanism of interfacial charge transfer and OER during the PEC process. The built-in electric field in band-matched BiVO 4 /LaCoO 3 and V(3 d )-O(2 p )-Co(3 d ) synergistic orbital hybridization at BiVO 4 /LaCoO 3 interface provide a low-barrier hopping pathway for electron transitions, which is favorable for the fast OER.

Silicon anodes for advanced lithium-ion batteries (LIBs) are promising due to intrinsic advantages including ultrahigh theoretical capacity (4200 mAh g −1 ), near-optimal Li + /Li potential (∼0.4 V), abundant availability and environmental benignity. However, practical application is hindered by severe intrinsic challenges: drastic volume expansion (>300%), unstable solid-electrolyte interphase (SEI) formation, and sluggish reaction kinetics. To address these limitations, we fabricated a novel Si@T-Nb₂O₅@Carbonized-coxial carbon nano fiber composite via a scalable hydrothermal-electrospinning approach, featuring silicon nanoparticles encapsulated in a nitrogen-doped porous carbon matrix with an engineered T-Nb₂O₅ interphase layer. Theoretical simulations demonstrate that the T-Nb₂O₅ interphase promotes Li + diffusion and reduces the energy barrier at carbon/Si interfaces. The optimized electrode exhibits excellent cycling stability and high-rate performance (1030.1 mAh g −1 after 100 cycles at 0.2 A g −1 ; 507.7 mAh g −1 after 500 cycles at 2.0 A g −1 ). Notably, flexible pouch cells maintain stable LED illumination under repeated mechanical deformation, indicating great practical potential. This integrated electrospinning strategy provides a scalable manufacturing platform for high-energy flexible batteries.

The degradation of organic pollutants through photocatalysis is currently a major research focus. Core–shell heterostructures of metal semiconductors have been widely recognized as an effective strategy for enhancing photocatalytic performance, particularly when alloy nanoparticles are incorporated due to their unique electronic and catalytic properties. However, conventional synthetic approaches typically rely on high-temperature and high-pressure conditions, which often induce undesirable particle overgrowth and aggregation. Herein, AuPt bimetallic alloy nanoparticles were successfully fabricated via two successive in situ redox processes under room-temperature and ambient-pressure conditions, which were in situ integrated with Cu2O to form multilevel core–shell composite particles. Structurally, an octahedral Cu2O crystal serves as the inner core (denoted as Cu2O(O)), sequentially coated with a Cu2O nanoparticle (denoted as Cu2O(P)) interlayer and a AuPt alloy nanoparticle shell. Functionally, the enhanced photocatalytic activity of Cu2O(O)@Cu2O(P)@AuPt was proven to be attributed to a dual function of AuPt, which includes an adsorption-induced polarized interface and an efficient charge-transfer mediator with the ohmic contact. This work demonstrates a mild and versatile synthetic strategy for constructing semiconductor–alloy heterostructures, offering valuable insights into the rational design of highly efficient and stable photocatalysts.

High-altitude environments provide a favorable basis for tea quality formation, but suitable processing parameters for high-altitude Oolong Tea (HAOT, Camellia sinensis (L.) O. Kuntze) remain unclear. This study optimized key processing parameters for HAOT using a three-factor, three-level orthogonal design involving withering method, shaking intensity and standing time. Sensory evaluation, quantitative descriptive analysis (QDA), macro-compositions determination, headspace solid-phase microextraction coupled with gas chromatography–mass spectrometry (HS-SPME-GC-MS), multivariate statistics and correlation analysis were used to clarify quality differences and their chemical basis. Leaf anatomical observation showed that high-altitude fresh leaves had a thicker cuticle and more compact mesophyll structure, suggesting the need for targeted processing regulation. Range analysis indicated that shaking intensity had the largest R value for sensory scores, followed by withering method, whereas standing time showed a comparatively small R value. The favorable combination was combined withering, heavy shaking (6 rounds) and 60 min standing, hereafter referred to as FHM. FHM showed the highest floral and fruity aroma scores and produced a mellow, full-bodied taste with a sweet aftertaste. It also contained significantly higher flavonoid and soluble sugar levels than the other processing combinations. A total of 65 volatile organic compounds were detected, with terpenoids and esters as the dominant classes. ROAV analysis identified geraniol, linalool, β-ionone, ( E )-nerolidol and benzaldehyde as representative major aroma-active compounds, while geraniol and linalool were especially prominent in FHM. Correlation analysis further linked flavonoids and soluble sugars with positive taste attributes, and linalool and geraniol with floral–fruity aroma. These results provide a practical basis for optimizing HAOT processing and improving product quality.

Abstract Nitrogen-doped carbon materials derived from metal–organic framework (MOF) have been commonly regarded as promising metal-free electrocatalysts for the oxygen reduction reaction (ORR). However, their performance is severely limited by nanoparticle agglomeration-induced sluggish mass transfer, insufficient ORR intermediate adsorption regulation by sole N doping, and structural damage from excessive heteroatom doping. Herein, we report a mesoscopic superstructure engineering strategy to fabricate moderately nitrogen–oxygen codoping MOF-derived carbon sphere superstructures (N/O-CNS) for high-performance ORR. A three-dimensional (3D) spherical MOF superstructure precursor was first constructed via urea-induced self-assembly of one-dimensional (1D) rod-like Zn-MOF-74, followed by one-step controlled pyrolysis to preserve the 3D hierarchical architecture and achieve uniform nitrogen–oxygen doping. The 3D superstructure provides abundant accessible catalytic centers and accelerated mass/electron transport rates. Density functional theory (DFT) calculations verify that, compared with sole N doping, nitrogen–oxygen codoping further optimizes the adsorption energy of the rate-determining *OOH intermediate and lowers the ORR reaction energy barrier. Regulated pyrolysis enables continuous tuning of nitrogen–oxygen codoping content and the graphitization degree of the carbon matrix, achieving a favorable trade-off among catalytic site population, charge transport efficiency, and structural integrity. Notably, the optimized N/O-CNS-1000 with the lowest doping content among all samples exhibits exceptional ORR activity in alkaline electrolyte, with an onset potential of 0.98 V and a half-wave potential (E1/2) of 0.83 V, outperforming commercial Pt/C. When assembled into rechargeable Zinc-air batteries (ZABs), the N/O-CNS cathode achieves a maximum power density of 140.55 mW cm–2 and good cycling lifespan of over 750 h.

Compared with traditional single emulsions, the distinct three-phase and two-interface structures of double emulsions enable them to simultaneously encapsulate and deliver hydrophilic and lipophilic compounds, which significantly broadens their applications. Here, cellulose nanocrystal (CNC)/β-lactoglobulin (β-LG) complexes and polyglycerol polyricinoleate (PGPR) were used to fabricate water-in-oil-in-water (W/O/W) emulsions. We first examined the influence of different PGPR concentrations (1.0, 3.0, 5.0, and 7.0 wt%) and O:W 1 mass ratios (9:1, 8:2, 7:3, and 6:4) on the stability of the primary W 1 /O emulsions. Building on this, the influence of different W 1 /O:W 2 mass ratios (1:9, 2:8, 3:7, and 4:6) on W 1 /O/W 2 emulsions was studied. We then utilized laser confocal microscopy to explore the internal environment of the emulsions and employed urea and sodium dodecyl sulfate as interventions to analyze the interactions at their interfaces. Finally, curcumin and epigallocatechin gallate were selected as model hydrophobic and hydrophilic nutrients, respectively, to confirm the promising applications of the W 1 /O/W 2 emulsion. Their encapsulation efficiencies reached 95.7 % and 86.8 % when co-loading in the W 1 /O/W 2 emulsion. Additionally, in vitro simulated digestion revealed that nutrients remained protected throughout oral and gastric stages, with controlled release occurring upon intestinal arrival, and their bioaccessibility was enhanced to 65.1 % and 71.6 %, respectively. The W 1 /O/W 2 emulsions we prepared and the elucidation of their underlying mechanisms have presented new possibilities for developing food and delivery systems in the future.

Development of high-performance photocatalysts for persulfate activation is often limited by rapid electron–hole recombination and insufficient quantum efficiency. To overcome the challenges, electronic metal–support interaction (EMSI) structure is designed. The innovative structure has several key benefits: recombination rates are significantly reduced, charge separation is enhanced, and content of active sites and intrinsic catalytic activity are increased. ZrO 2 /Co 3 O 4 bimetallic oxides featuring a synergistic Co─O─Zr EMSI coordination are synthesized via a sol-gel method. Strong EMSI effects markedly modulate and stabilize the Co 3d electronic structure, creating an electron-rich center on Co sites to promote persulfate activation, and an electron-deficient center on Zr sites to adsorb atrazine. The Gibbs free energy analysis reveals that Zr incorporation reduces the overpotential of oxygen evolution reaction, thereby facilitating electron transfer, promoting hole consumption and suppressing charge recombination. More importantly, it promotes the generation of reactive oxygen species—predominantly via a singlet oxygen ( 1 O 2 )-dominated non-radical mechanism. The optimized catalyst achieves 97.3% degradation of atrazine (a model compound) under visible light, outperforming commercial catalysts (e.g., 4.5-fold of Co 3 O 4 ). The work elucidates the cooperative mechanism of dual-site engineering and EMSI-mediated electron redistribution, providing a rational strategy for designing efficient photocatalysts toward sustainable advanced oxidation processes.
