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.

Lignin-derived bio-oils contain abundant methoxyphenols exhibiting limited antioxidant activity, which requires their conversion to high-value polyphenols. This study develops titanium-loaded Hβ zeolite catalysts (xTi/Hβ) for the selective O-demethylation of methoxyphenols to catechols under subcritical aqueous conditions. Comprehensive characterization (XRD, XPS, STEM, NH₃-TPD, Py-FTIR) reveals that Ti exists as both framework-incorporated tetrahedral Ti⁴⁺ species (via Al³⁺ substitution) and surface-anchored anatase TiO 2 nanoparticles (NPs). The optimal 5Ti/Hβ catalyst maximizes synergistic effects: framework Ti sites enhance Brønsted acidity, while Ti NPs facilitate H 2 O enrichment near active sites. This achieves 99.46% conversion of 4-propylguaiacol to 4-propylcatechol. Applied to distilled bio-oil, 5Ti/Hβ reduces methoxyphenol content from 48.50 Area.% to 20.25 Area.% and increases total polyphenols from 25.39 Area.% to 43.64 Area.%. Catalyst stability challenges under prolonged hydrothermal conditions are identified for future optimization.

Halide solid-state electrolytes (HSSEs), exemplified by low-cost Li 2 ZrCl 6 , exhibit high ionic conductivity and a wide electrochemical stability window, making them promising for all-solid-state batteries (ASSBs). Yet, optimizing HSSEs by elemental doping is either inefficient or costly, necessitating alternative approaches. Inspired by the filler-modified LiI-Al 2 O 3 system with fast-conductive interfacial percolation layer (IPL) and with regard to the underlying insufficient interfacial filler/electrolyte contact with Li 2 ZrCl 6 matrix, which hinders the IPL formation, the use of transition metal oxide Fe 2 O 3 is pioneered as a filler to generate oxygen vacancies and foster benign filler/electrolyte interfaces. At the Fe 2 O 3 /electrolyte interface, synchrotron X-ray adsorption spectra and electron energy loss spectra mapping reveal a distinctive O-Cl exchange reaction and improved interfacial contact. Density function theory, bond-valence site energy calculations, and finite-element simulations validate improved Li + migration via mitigated electrostatic confinement, reduced migration energy barriers, and spatially confined electric-field-accelerated IPLs. Benefiting from these merits, the ionic conductivity of the composite electrolyte surges from 0.4 to 2.15 mS cm −1 , with Li + migration activation energy reduced to 0.28 eV. Paired with the NCM811 cathode, the ASSB delivers 90% capacity retention over 1000 cycles at 0.5 C. This work offers a novel, cost-effective strategy for high-performance halide-oxide composite electrolytes from the counterintuitive perspective of nanofiller integration.

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.

This study developed a dilute acid pretreatment method (0.3 M HCl) for the efficient production of nanochitin, achieving a yield of 87.14%. The obtained nanofibrils measured 271.15 ± 13.64 nm in length and 10.25 ± 0.50 nm in width, with a crystallinity of 87.15%. This strategy demonstrated a comparable hydrolysis effect to the conventional 3 M HCl method. A Pickering emulsion with smaller droplets and excellent emulsification performance was prepared by homogenizing nanochitin and gelatin at a total mass concentration of 1%. When the nanochitin-to-gelatin ratio was 5:5, the storage modulus of the emulsion was approximately 2.5 times that of the system stabilized by gelatin alone. Furthermore, increasing the mass concentration above 2% resulted in the formation of an emulsion gel, which exhibited significantly enhanced rheological performance and stability.

Egg white gel (EWG) is a highly important raw and auxiliary material in food industry. With the increasing demand of consumers for nutrition, developing a modification method for regulating the texture of traditional egg white gel while enhancing its nutritional efficacy has become a challenge. Herein, a hierarchical W/O/W double emulsion filled gel was fabricated via a two-level emulsification process. The primary W/O emulsion, stabilized by synthesized γ-cyclodextrin metal-organic frameworks (CD-MOFs) Pickering emulsifiers, was incorporated into an egg white solution, where the endogenous emulsifying properties of the proteins facilitated the formation of the secondary O/W interface. The stability and morphology of the CD-MOFs-stabilized W/O emulsion (CDME) were analyzed, and the gel properties, molecular interactions, and microstructure of the W/O/W emulsion filled EWG gel (CDME-EWG) was then evaluated. The results indicated that CD-MOFs at 6 mg/mL (CDME-6) significantly enhanced the stability of the Pickering emulsion. This effect was achieved through the formation of a dense interfacial film at the oil/water boundary, which effectively promoted droplet dispersion and suppresses coalescence. Furthermore, the emulsion filled gel with 6 mg/mL CD-MOFs (CDME-EWG6) promoted the cross-linking within the gel network, leading to a more compact structure, enhanced water retention (52.84%) and hardness (887.00 g), as well as the enhancement in encapsulation capability (81.77%) and bioavailability (41.18%) of lutein. This study proposed a novel strategy for improving the performance of protein gels, which also provided the potential for co-encapsulation of multi-component bio-actives via the porous CD-MOFs and compartmentalized chamber within the W/O/W emulsion

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.

Hollow Carbon Spheres co-doped with nitrogen(N) and oxygen(O) (NOHCS) with high specific surface area (422 m 2 g − 1 ) have been successfully fabricated through calcination and carbonization in nitrogen gas in the presence of SiO 2 nanoparticles as the templating agent, phenolic resin as the carbon precursor, and melamine as the nitrogen precursor. The material has hierarchical porous structure, hollow frame and synergistic effect of N and O, which can alleviate the volume expansion effect, increase the sulfur load, significantly improve the conductivity of carbon material, and effectively alleviate the shuttle effect of lithium-sulfur battery. The NOHCS/S-0.12 composite material has a very high initial discharge capacity of 1029 mAh g − 1 and a specific capacity of 541 mAh g − 1 after 200 cycles at 0.1 C, showing good cycling stability. It has strong electrochemical reversibility and small electrochemical impedance of the cell, which shows electrode polarization of only 0.38 V. These results indicate that the hollow structure has a synergistic effect with N and O co-doping, effectively limiting the dissolution and diffusion of polysulfide. N–O co-doped hollow carbon spheres have good development potential in the application of lithium-sulfur batteries.

High temperature thermally stable fiber materials with flexibility are expected to be applicable to severe conditions. In this article, ZrO 2 /Si–C–O ceramic fibers have been synthesized by the sol-gel process combined with the electrospinning technique. We focus on the changes of composition, structure and morphology with the increasing heat treatment temperature. More importantly, the effects of ZrO 2 crystalline phase transformation on mechanical property of ZrO 2 /Si–C–O ceramic fibers have been investigated. The results show that the increased temperature can lead to an increase of the fiber diameter and grain size, as well as the transformation of ZrO 2 phase. It is also found that the ZrO 2 /Si–C–O ceramic fibers possess refined crystalline grain and improved mechanical properties at a heat treatment temperature of 800 °C, which is mainly due to the fact that the amorphous Si–C–O phase containing free carbon facilitates the refinement of the crystalline grain, and the ZrO 2 in the tetragonal structure improves the flexibility of ceramic fibers. Furthermore, the obtained fibers exhibit excellent thermal stability up to 1300 °C, therefore they have broad application prospect in high temperature environment.

A series of Schiff-base functional groups modified MCM-41 materials have been synthesized and used as the supports of palladium species. The chemical structures of MCM-41 functionalized by nine Schiff-base functional groups were characterized by Fourier transform infrared spectroscopy (FT-IR), whereas their grafting densities of functional groups were achieved from the results of thermogravimetric analysis (TGA) and elemental analysis (EA). Small angle powdered X-ray (SAX) patterns demonstrate that the ordered mesoporous structures of MCM-41 were well retained after modification of functional groups and immobilization of Pd 2+ cations. Moreover, the regular mesoporous structures of supports and homogeneous dispersions of Pd 2+ cations were characterized by transmission electron microscopy (TEM). The positron annihilation lifetime spectroscopic (PALS) results revealed that the electronic and steric factors of functional groups could affect the o -Ps annihilation properties of support Pd 2+ cations. Meanwhile, the catalytic activities of these supported Pd 2+ cations chelated by different functional groups were determined by the Heck reaction of iodobenzene with n -butyl acrylate. At last, the catalytic activities of these supported Pd 2+ cations were linearly correlated to their o -Ps annihilation properties. This result demonstrates that the catalytic activities of supported Pd 2+ cations chelated by different functional groups can be readily determined by the o -Ps annihilation, which can be potentially used in the design and preparation of highly active palladium catalysts.

Ru/AC catalyst used in acetylene hydrochlorination reaction has several drawbacks such as poor dispersion, metal loss, serious carbon deposition, and insufficient active sites. To address these issues of traditional Ru/AC, in this study, the supported Ru-L x /AC catalysts were synthesized by the coordination of ruthenium precursor and several structural triazine ligands. The complexation of heteroatomic structure to Ru atom formed a local active domain, which is more conducive to the synergistic adsorption and activation of the initial reactants, and further optimizes the reaction microenvironment. The spatial topological structure with conjugated structures effectively promoted the transfer of electrons between the heteroatoms and the ruthenium precursors, facilitating the stabilization of active Ru species. The newly developed synthetic process also increased dispersion of reaction components and impeded the sintering of ruthenium components promoted by the local structural forces. The optimum Ru-1,3,5-triazine/AC (Ru-L 1 /AC) catalyst exhibited 162% higher acetylene conversion than the benchmark Ru/AC catalyst. The significantly improved activity and stability of the optimized catalyst will have a huge application prospect in industry.
