The efficiency of electron utilization and C–C coupling is crucial to the selectivity of photocatalytic CO2 reduction to multicarbon (C2+) hydrocarbon products. Herein, the multifunctional catalyst of TiO2-modified W18O49 nanospheres (TimWOx) was successfully fabricated by in situ growth hydrothermal method. The distinct interfacial energy between W18O49 and TiO2 can promote the charge redistribution at the asymmetric Ti–O–W active sites and facilitate the formation of an internal electric field (IEF). Photogenerated electrons driven by the IEF can improve the dynamic electron shuttling between Ti and W centers for enhancing electron utilization efficiency during CO2 photoreduction. TimWOx catalysts exhibit high activity for photocatalytic CO2 reduction to C2+ products, i.e., the yield and selectivity of C2H4 over Ti0.25WOx are 46.3 μmol·g–1 and 72.01%, respectively, which is 7.25 times that of pristine W18O49. Combined with the results of in situ diffuse reflectance infrared Fourier transform spectra and DFT calculations, the photocatalytic mechanism is proposed: the protonation the *OCCOH intermediate is key step for selective photocatalytic CO2 reduction into C2H4, and the energy barrier for the protonation of the *OCCOH intermediate is lowered by IEF-induced dynamic electron shuttling, which selectively steers the reaction pathway toward C2H4 formation. This work highlights the role of interfacial electric fields in guiding electron shuttling for selective photocatalytic C–C coupling, which benefits developing highly efficient photocatalysts.

In this work, oil-in-water (O/W) benzyl isothiocyanate (BITC) nanoemulsions (10% MCT) were prepared with four natural emulsifiers: chitosan, gum arabic, soybean protein isolate (SPI), and SPI-phosphatidylcholine (SPI-PC). We evaluated the effects of emulsifier type and concentration (0.25–4 wt%) on the nanoemulsions’ encapsulation efficiency, rheological behavior, stability, and antioxidant capacity. Results showed that at the same concentration, protein-based (SPI/SPI-PC) nanoemulsions had smaller particle size, higher absolute ζ-potential, and better encapsulation efficiency than polysaccharide-based (chitosan/gum arabic) counterparts. All four emulsifiers delivered the smallest particle size and highest encapsulation efficiency at 1 wt%, with SPI-PC nanoemulsion reaching 234.17 ± 1.27 nm and 93.21 ± 2.27%, respectively. Confocal laser scanning microscopy (CLSM) confirmed SPI-PC nanoemulsion had smaller, uniform droplets, with the lowest Turbiscan Stability Index (TSI, 0.20 ± 0.01, excellent stability). It also showed the lowest viscosity and shear stress, and highest 1,1-diphenyl-2-picrylhydrazyl (DPPH, 71.60 ± 1.81%) and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS + , 79.43 ± 2.40%) radical scavenging activity. These results confirm the SPI-PC complex forms a more efficient, stable emulsification system, providing support for developing natural food-grade emulsifiers and lipophilic bioactive delivery carriers.

Traditional propylene oxide (PO) production processes consume large amounts of organic feedstock and release hazardous by-products. The synthesis of PO via the epoxidation of propylene using O 2 is an ideal route offering 100% atomic economy. However, achieving high selectivity and high efficiency under mild conditions remains a significant challenge. In this study, we have developed a visible-light-driven tandem reaction system combining a carbon- and oxygen-co-doped three-dimensional spherical indium sulfide (C,O-In 2 S 3 ) photocatalyst with titanium silicate molecular sieve (TS-1), thereby achieving the distinctly selective oxidation of propylene at ambient temperature. Assembled from ultra-thin nanosheets, the three-dimensional structure of C,O-In 2 S 3 provides abundant active sites and mass transfer space, with carbon‑oxygen co-doping narrowing the bandgap and enhancing visible light absorption. In a pure water system, the H 2 O 2 yield of C,O-In 2 S 3 reached 1450.40 μmol·g −1 ·h −1 , which is 17.8 times that of pristine In 2 S 3 . Utilizing the excellent compatibility of the methanol/water system, the photocatalytic generated H 2 O 2 was directly employed in the TS-1-catalysed epoxidation of propylene, achieving a PO yield of 2230.03 μmol·g −1 within 2 h with a selectivity of 99.1%. This work applies sulfide-based photocatalysts to a tandem reaction involving photocatalytic H 2 O 2 production and propylene epoxidation, providing a new strategy for the green, safe and efficient synthesis of PO.

A novel W₁/O/W₂ double emulsion was engineered via sodium alginate internal gelation. • Internal aqueous gelation enhanced the compactness and stability of double emulsions. • Modulated viscoelasticity created a robust barrier for Lactobacillus plantarum . • Microcapsules exhibited a honeycomb network with high solubility and rehydration. • The solid microcapsule matrix further prolonged the storage stability of probiotics. The sensitivity of probiotics to environmental stress significantly restricts their widespread application. Here, a novel W₁/O/W₂ double emulsion was constructed via sodium alginate–mediated internal gelation, and its physicochemical properties and protective efficacy for Lactobacillus plantarum were evaluated. Results showed that internal gelation significantly remodeled the emulsion microstructure, creating a compact internal assembly positively correlated with gelation intensity. Compared to the non-gelled control, the gelled emulsions exhibited superior physical, storage, and centrifugal stability, with the 1% alginate gelation intensity achieving the optimal stabilization effect. Rheological data demonstrated that the sodium alginate gel network formed in the internal aqueous phase greatly increased emulsion viscosity. It also modulated the viscoelastic behavior and built a robust physical barrier. This reinforced internal microenvironment markedly improved emulsion stability and effectively mitigated external stress, thereby significantly enhancing the viability of the entrapped probiotics. Furthermore, to further strengthen this protective effect, microcapsules fabricated via freeze-drying exhibited a uniform and dense honeycomb-like cross-linked network, characterized by excellent rehydration properties, solubility, and low moisture content. These solid microcapsules provided enhanced resistance against environmental stress, further improving the storage stability of the probiotics. In conclusion, the hierarchical strategy combining sodium alginate–mediated internal gelation and microencapsulation offered a robust engineering approach for the high-efficiency preservation of probiotics.

Red phosphorus (RP) is a promising anode material for sodium-ion batteries (SIBs) due to its high theoretical capacity and cost-effectiveness. However, its practical use is constrained by poor electronic conductivity and severe volume expansion during cycling. Herein, we introduce a new strategy to synthesize phosphorus/carbon (P/C) composites enriched with phosphorus-oxygen-carbon (P– O –C) bonds, achieved by high-energy ball milling of CO 2 -derived oxygen-rich electrolytic carbon (EC) with RP. This approach enhances the conductivity and structural stability of RP while effectively mitigating volume changes during charge-discharge cycles. Electrochemical evaluation reveals that the P/EC composite exhibits outstanding performance, maintaining a high capacity of 871.6 mAh g −1 after 200 cycles at 0.26 A g −1 with a retention rate of 88.6 %, and delivering 340.2 mAh g −1 after 2000 cycles at 2.6 A g −1 . This work demonstrates the potential of integrating CO 2 -derived EC with RP to create advanced anode materials with enhanced stability and high-rate capability, paving the way for next-generation SIBs.

Te -flavor Baijiu is renowned for its complex sensory profile, which evolves significantly during ageing, though the aroma-active compounds driving these changes remain underexplored. To systematically evaluate the effects of ageing duration on its flavor properties, this study conducted a comparative analysis of samples aged for 0, 3, 5 and 10 years. The results demonstrated that esters exerted predominant influence on flavor development during ageing. In the initial ageing periods, ester concentrations increased markedly, with ethyl hexanoate emerging as a pivotal compound due to its high concentration and substantial odor contribution. Notably, distinct differences in aroma and taste were observed across ageing periods, with fresh Baijiu (0Y) exhibiting higher sweetness. Multivariate statistical analysis revealed distinct aroma profiles across ageing periods and identified 13 key aroma compounds that form the unique flavor skeleton of Te -flavor Baijiu. This study elucidates the flavor evolution dynamics during the ageing process of Te -flavor Baijiu, providing fundamental insights for process refinement and quality control in Baijiu production.

In this study, the aim was to prepare pH responsive O/W 1 /W 2 double emulsions using carboxymethyl cellulose/chitosan (CMC/CS) via associative phase separation. The O/W 1 /W 2 double emulsions with different internal phase fractions (10 %, 20 %, 30 %, 40 %, 50 %, v /v) were prepared and the properties of the prepared O/W 1 /W 2 double emulsions was further investigated in the present work. The zeta-(ζ) potential and FTIR analysis confirmed that O/W 1 /W 2 double emulsions were mainly driven by electrostatic interaction and hydrogen bonding. The microstructure results showed that the O/W 1 /W 2 double emulsion droplet-aggregated gels with the highest double emulsion droplet density was formed as the internal phase fraction was 40 %, while the W 1 /W 2 interface of the O/W 1 /W 2 double emulsions was broken as the internal phase fraction was 50 %. Rheological property and stability results further confirmed that the O/W 1 /W 2 double emulsions with 40 % internal phase fraction had the best stability and dense network structure. In addition, CLSM result showed that the O/W 1 /W 2 double emulsions had excellent pH responsivity and the W 1 /W 2 interface had ion permeability and contractility. Furthermore, the rheology and stability results displayed that the prepared O/W 1 /W 2 double emulsions had pH reversibility. Therefore, this study provided a theoretical basis for the construction of pH responsive O/W 1 /W 2 double emulsion.

The extensive application of cyhalofop-butyl, an aryloxyphenoxypropionate (AOPP) herbicide, for weed control in rice fields inevitably results in environmental pollution and ecological toxicity. Microbial degradation of cyhalofop-butyl is garnering immense research attention. This study revealed that Sphingobium yanoikuyae B1 can efficiently degrade the cyhalofop-butyl, completely breaking down 30 mg/L within 12 h via ester bond hydrolysis, forming cyhalofop acid. A novel hydrolase gene cbeH (37.39% identity) was identified in B1. CbeH exhibited catalytic activity by hydrolyzing the ester bond (C-O) in cyhalofop-butyl and other AOPP herbicides, yielding AOPP acids. Additionally, it catalyzed the cleavage of the C-N bond in amide herbicides propanil and diuron, as well as the C-C bond in the aromatic compound 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoic acid. Sequence alignments and site-directed mutagenesis indicated the catalytic triad Ser-His-Asp in CbeH serves as active center cleaving C-O, C-C, and C-N bonds. Comparative analysis revealed the gene cbeH , highly conserved within Sphingomonads , was located within multiple insertion sequences on the plasmid of Rhodococcus strains. CbeH was widespread in Proteobacteria and Actinobacteria, with its host strains prevalent in aromatic-polluted environments. This study provides novel enzyme resources for remediating combined pollution and enhances our understanding of the genetic organization and environmental distribution of trifunctional pollutant-degrading genes.

Ceramic fibrous aerogels are promising lightweight thermal insulators, yet concurrently enhancing mechanical robustness, acoustic attenuation and electromagnetic (EM) wave absorption remains challenging because these functions demand conflicting architectures. Here we introduce a phase-transition-driven multiphase evolution strategy in Si Zr crystals combined with a one-step thermally induced core–shell conversion. This approach enables coordinated regulation of the chemical states, dislocation density and oxygen-vacancy concentration in Zr Si ceramic fibers, and forms a heterogeneous “oxide shell (ZrO 2 /SiO 2 )-carbide core (SiC/ZrC)” within each fiber. The resulting interfacial enrichment and improved impedance matching synergistically strengthen the aerogel and boost EM dissipation. The obtained ZSCO fibrous aerogels deliver a compressive stress up to 255.73 kPa, a minimum reflection loss of −21.87 dB and an average sound absorption coefficient of 0.61. Mechanistic analysis reveals a thermally driven, multimodal regulation pathway for tailoring multifunctional ceramic fibers, offering a scalable route to aerogels for extreme environments.

It is a challenging work to design novel responsive materials by controlling the secondary structure of polypeptide , especially β-sheet. We designed and synthesized a novel dual responsive diblock copolymer of methyl poly (ethylene glycol)- b -poly (O-benzyl- l -threonine) (mPEG- b -PBnLT). The copolymer solutions exhibited unusual and reversible gel-to-sol-to-gel transition behavior with temperature, and the transition temperature window could be easily adjusted by changing copolymer concentration or PBnLT block length . It was confirmed that low temperature gel-to-sol transition was due to the disassembly of the preliminary β-sheet layered nano-assemblies that induced the transformation of self-organized morphology from nanosized fibrils to spherical aggregates, while the high temperature sol-to-gel transition was ascribed to the dehydration of PEG segments. The disassembly of β-sheet structures was caused by the change in the polarity of the pendant benzyl ether bond of PBnLT block in water with temperature. This stimuli-responsiveness of secondary self-assembled nanostructures and the corresponding change in macroscopic phase transition inspires a brand-new strategy for structural design and functional control of polypeptide materials.

This study investigated the effects of mechanical treatments, namely magnetic stirring (S), high-shear homogenization (HS), and ultrasonication (150, 300, and 600 W), on the sugarcane wax-based oil-in-water (O/W) emulsion and its integration into carboxymethyl cellulose (CMC)-based packaging films. The objective was to tackle issues, such as hydrophilic properties in CMC films and wax particle aggregation, by enhancing emulsion characteristics. Of the formulations, S/HS/300 W exhibited superior performance, attaining homogenous particle sizes ≤1 μm, a low polydispersity index (21.12), and a high ζ-potential (−41.55 mV), signifying improved stability. It also showed enhanced thermal stability, reduced crystallinity, and valuable rheology. Incorporating the S/HS/300 W emulsion into CMC films markedly improved water resistance, elevated hydrophobicity (115.5° water contact angle), decreased water vapor permeability by 23%, offered UV light protection dropped by 0%, decreased visible light transmission, and boosted mechanical qualities; the tensile strength rose by 34.2%. This study underscores the efficacy of mechanical processing in the production of high-performance films for sustainable packaging.

High-performance Al₂O₃-Ti(C,N) composites are critical for extreme-environment applications, yet conventional static sintering cannot simultaneously achieve full densification and strong grain-boundary bonding. Here, a dynamic sinter forging (DSF) strategy coupling sintering densification and oscillatory forging deformation was developed to activate plastic flow and defect engineering. Composites were sintered at 1600 °C with oscillatory amplitudes of 0–40 MPa (5 Hz) and a maximum pressure of 80 MPa. The flexural strength increased from 583 MPa under a pressure of 80 ± 0 MPa to 1070 MPa under 40 ± 40 MPa, representing an 83 % enhancement. TEM revealed increased dislocation densities in Al₂O₃ (2.6 ×10⁵→2.9 ×10⁶ cm⁻²) and Ti(C,N) (4.8 ×10⁶→8.2 ×10⁶ cm⁻²) and curved interfaces, shifting fracture from intergranular to transgranular, showing that defect generation and interface curvature jointly strengthen the composites. This DSF route enables concurrent densification and microstructural strengthening within a single thermal cycle, offering a general pathway to high-toughness oxide–carbonitride ceramics.
