Kaempferol-3-O-sophoroside was a marker of Gentiana macrophylla Pall. • monofloral honey (GH). • SEM and UHPLC–DAD-QTOF-MS/MS enabled reliable botanical authentication of GH. • GH was enriched in flavonoids and phenolics compared with common honeys. • GH exhibited significant antioxidant and antibacterial activities. As a medicinal plant–derived honey, Gentiana macrophylla Pall. monofloral honey (GH) remains insufficiently characterized in terms of botanical authentication and characteristic chemical markers. The objective of this study was to identify a marker compound for GH and to evaluate the physicochemical characteristics and bioactive properties. The botanical origin of GH was verified by SEM observation, revealing that Gentiana macrophylla Pall. pollen grains are monad, isopolar, radially symmetrical, with a tricolporate aperture system. Kaempferol-3-O-sophoroside was identified as a potential characteristic compound by UHPLC–DAD-QTOF-MS/MS, with a content of 331.06 ± 19.96 μg/kg in GH. Due to the abundant total flavonoid (34.98 ± 0.31 mg Rutin/kg) and total phenolic contents (283.68 ± 3.07 mg GAE/kg) compared with other common commercial honeys, GH exhibited significant antioxidant capacity and antibacterial activity against E. coli MG1655 and S. aureus 23,923. Consequently, kaempferol-3-O-sophoroside, as a potential authentication marker for GH, contributes to the improvement of bioactivity.

Antibiotics like doxorubicin hydrochloride (DOX) are widely used in medicine, but their environmental residues pose risks to human health and ecosystems. This study optimized the synthesis of C-Fe₃O₄@ZIF-8 composites using response surface methodology (RSM) to enhance DOX release efficiency, thereby mitigating environmental antibiotic contamination. Under optimized conditions (37 °C, pH 5.0), the C-Fe₃O₄@ZIF-8 composite achieved a significant increase in cumulative DOX release, from 40.8% to 61.1%. The pH-responsive release further validated the optimization strategy. Characterization via scanning electron microscopy (SEM) and X-ray diffraction (XRD) revealed a structural transformation from rhombic dodecahedral crystals to more stable spherical particles with enhanced crystallinity. Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) confirmed an increase in surface-active sites and oxygen-containing functional groups, contributing to improved drug release efficiency. These findings provide valuable insights into optimizing C-Fe₃O₄@ZIF-8 for drug delivery, advancing environmentally friendly antibiotic management strategies.

The effects of Y₂O₃–LiF sintering additives on the microstructure, thermal conductivity, flexural strength, and dielectric properties of AlN-based ceramics were systematically investigated. Six different compositions were prepared via ball milling, hot-press sintering, and annealing. XRD and Rietveld refinement confirmed a hexagonal structure for all samples, with changes in the Al–N bond length along the C-axis. SEM analysis revealed that the Y₂O₃–LiF additives modified the morphology of the secondary phase while maintaining a high bulk density. Moreover, annealing resulted in grain boundary purification. As LiF content increased, the second-phase morphology evolved from oval to strip-like, and annealing reduced this phase, improving overall performance. Raman spectroscopy indicated lattice expansion and a blue shift with increasing LiF content. Dielectric analysis of the 2 wt% LiF–Y₂O₃ sample revealed a dielectric constant of 8.56, a dissipation factor of 2.1 × 10⁻⁴, and a high activation energy of 1.38 eV.

Transition metal oxyhydroxides are crucial for the electrochemical oxidation of 5-hydroxymethylfurfural (HMF), though the co-adsorption and activation mechanisms of HMF and hydroxyl species require further clarification. This study designs cerium-doped Co-based layered double hydroxide (LDH) arrays, including 3%Ce-Co 3 Fe 1− x Al x -LDH/NF, to investigate Fe as a secondary active center and the role of Ce–O–TM (Transition metal) bridges in regulating HMF/OH − adsorption. Theoretical calculations indicate that Ce–O–TM bridges induce f – p – d gradient orbital coupling, optimizing HMF/OH − adsorption configurations and facilitating the HMF oxidation reaction (HMFOR). Synchrotron radiation characterization and in situ Raman spectroscopy reveal that Fe enhances electronic interaction between Ce and Co/Fe sites, strengthening the stability of M–O bonds, suppressing metal dissolution, and further optimizing reactant adsorption. Fe doping also modulates charge distribution and accelerates charge transfer. The optimized 3%Ce-Co 3 Fe 1 -LDH/NF delivers industrial current density (0.1 A cm −2 ) at 1.44 V RHE , with 98.1% HMF conversion, 99.6% FDCA yield, and 99.8% Faradaic efficiency. In an anion exchange membrane (AEM) electrolyzer, it achieves 0.5 A cm −2 at 2.1 V while maintaining high stability across 0.1–0.5 A cm −2 . These results provide an effective strategy for designing high-performance HMFOR catalysts through electronic structure modulation.

Bismuth oxide (Bi 2 O 3 ) is widely used in photocatalytic oxidation degradation of organic pollutants due to its simple composition, green environmental protection and stable structure. However, the limited specific surface area (SSA) and the slow charge kinetics significantly limit its photocatalytic ability. Here, Bi 2 O 3 /MWCNTs heterojunctions were synthesized using hydroxylated multi-walled carbon nanotubes (MWCNTs-OH) as the substrate, explore the crystal growth mechanism and apply it to photocatalytic oxidation reactions. The one-dimensional (1D) structure and excellent electrical conductivity of MWCNTs-OH provide a special transport path for the spatial separation of photogenerated electrons and holes. The stable chemical properties and unique hollow cavity structure of MWCNTs-OH significantly increase the specific surface area of Bi 2 O 3 /CNTs. The optimized Bi 2 O 3 /CNT-3 demonstrated outstanding performance in the photocatalytic oxidation degradation of organic substances such as lignin and RhB. The photocatalytic activity of lignin degradation under visible light has increased by 5.8 times, and the performance of RhB removal has increased by 6.7 times.

This study aimed to enhance the stability and functional properties of W/O/W emulsions through a biphasic gelation strategy. An emulsified gel system was constructed with soybean lipophilic protein-chitosan hydrochloride complex (SLP-CHC) as the emulsifier, beeswax as the oil-phase gelling agent, and curdlan/anhydrous calcium chloride as the aqueous-phase gelling agent. The microstructure and physicochemical properties were characterized, and in vitro digestion experiments were conducted to evaluate the protective and delivery capacities for vitamin B 12 (VB 12 ) and vitamin E (VE). The biphasic gel exhibited a dense network, high viscoelasticity (G' > G”), and superior water/oil-holding capacity. Encapsulation efficiencies reached 95.92% for VB 12 and 69.51% for VE, with enhanced stability under heat and pH stress compared to single-phase gels. In vitro digestion confirmed effective gastric protection and intestinal release, leading to high bioaccessibility for both vitamins. This study provides a novel approach for the co-delivery of polar and non-polar bioactive compounds.

Selective hydrogenolysis of C–O bonds in lignin is widely regarded as the most promising strategy for generating high-value chemicals and clean liquid fuels. Ni–Ru bimetallic catalyst supported on solid superacid was successfully synthesized and applied to the cleavage of C–O bonds in diphenyl ether (DPE) and alkali lignin. The catalytic hydrogenolysis of DPE over a 10%Ni–0.5%Ru–S2O82–/ZrO2 catalyst produced 88.0% cyclohexanol. Additionally, 10%Ni–0.5%Ru–S2O82–/ZrO2 catalyzed the depolymerization of alkali lignin in high yields of phenolic compounds, primarily including guaiacol and methoxyphenol. The synergistic effect between Ni and Ru promoted electron transfer from Ni to Ru. The incorporation of Ru improved the dispersion of Ni and reduced the average particle size of metallic Ni. The strong acidity of the solid superacid support provided abundant acidic sites, facilitating hydrogen atom adsorption and thereby promoting C–O bonds cleavage.

A new strategy for enhancing the
hydrazine structure based on the
inductive effect and conjugation effect of strong electron-withdrawing
groups has been designed to effectively absorb CO 2 with
hydrazide-based ionic liquids (ILs). All three ILs aqueous solutions
(diethylenetriamine oxalyl dihydrazide [DETAH] 2 [ODH], diethylenetriamine
propanedioyl dihydrazide [DETAH] 2 [PDH], and diethylenetriamine
succinic dihydrazide [DETAH] 2 [SDH]) exhibit good absorption
performance. Through a combination of absorption–desorption
experiments, FT-IR and NMR characterizations, and density functional
theory (DFT) calculations, the results indicate that the unique structure
of anions enables physical adsorption to occur again after chemically
absorbing CO 2 . The special absorption process is responsible
for the unusual regeneration properties. Hopefully, the results of
this work are helpful in providing a new method for designing highly
efficient gas absorbents.

DMS gradient improves micropore access and O₂ transport, reducing flooding. • CB-DV06 yields 750 mg L −1 H₂O₂ at >60% Electro-Fenton efficiency. • DMS-modified GDEs remove 85% RBB and reduce TOC 60% in 120 min. • Surface area reaches 222.9 m 2 /g; electroactive sites increase sixfold. • Dual-phase oxygen diffusion boosts ORR kinetics and degradation rate. Hydrogen peroxide (H₂O₂) electrosynthesis via the two-electron oxygen reduction reaction (2e − ORR) is critically dependent on the formation of stable and well-regulated triple-phase interfaces (TPIs), where gas, liquid, and catalyst converge. However, micropore flooding and uneven wettability in carbon-black gas diffusion electrodes (GDEs) often hinder oxygen transport and deactivate active sites. In this work, we address these challenges by introducing a dimethyl silicone oil (DMS) volume-gradient strategy to engineer confined TPIs within the carbon catalyst layer. Carbon-black GDEs were prepared using DMS volume-controlled of 0.4, 0.6, and 1.2 mL, with CB-DV06 identified as the optimum configuration. This design balances hydrophobicity and pore accessibility, promoting sustained oxygen diffusion and suppressing water blockage without impeding electron or ion transport. The optimized GDE (CB-DV06) achieved ~750 mg L −1 H₂O₂ after 180 min with current efficiencies exceeding 60% and enhanced electrochemically active surface area. To demonstrate the practical applicability of the in situ generated H₂O₂, Reactive Black B (RBB) degradation was employed as a model pollutant-removal reaction. The integrated system achieved approximately 85% RBB decolourisation, demonstrating the applicability of this interface-engineering strategy for pollutant-removal applications. Overall, this study highlights a low-impact approach for optimizing oxygen reduction environments in porous electrodes, advancing sustainable oxidant generation and environmental remediation.

A PTFE-based composite with surface-modified Zr₂O(PO₄)₂ (ZOP) filler was developed for high-frequency applications. • FAS-17 surface modification improves tZOP-PTFE compatibility and filler dispersion while reducing visible defects. • PTFE@tZOP-40 exhibits an ultralow dielectric loss (D f = 5.5 ×10 −4 at 10 GHz) and a reduced CTE of 51.6 × 10 −6 K −1 . With the increasing demand for advanced dielectric materials in high-frequency microwave and millimeter-wave systems, polytetrafluoroethylene (PTFE) has attracted considerable attention due to its low dielectric constant, low dielectric loss, and excellent electrical insulation. However, its high coefficient of thermal expansion (CTE) may cause dimensional instability and reliability issues in high-frequency substrate applications. In this study, zirconium oxophosphate (Zr₂O(PO₄)₂, ZOP), an ultralow-CTE ceramic filler, was incorporated into the PTFE matrix to develop composites with reduced thermal expansion and favorable dielectric performance. To improve the compatibility between hydrophilic ZOP and hydrophobic PTFE, ZOP particles were surface-modified using a fluorinated silane coupling agent to obtain tZOP. The modified tZOP showed improved dispersion in the PTFE matrix and reduced visible defects, contributing to a denser composite microstructure and enhanced thermal dimensional stability. At a filler loading of 40 wt%, the PTFE@tZOP composite achieved a CTE of 51.6 × 10 −6 K −1 , a dielectric constant of 2.83, and a dielectric loss of 5.5 × 10 −4 at 10 GHz. This work demonstrates an effective surface-modification strategy for developing PTFE-based composites with low thermal expansion and favorable dielectric properties for next-generation high-frequency substrates.

Co-doped CeO 2 creates synergistic Co-O-Ce interfaces and oxygen vacancies. • Distinct CH 3 OH and CO 2 activation sites alleviate competitive adsorption. • Achieves high DMC yield of 16.5 mmol·g −1 ·h −1 under 2 MPa CO 2 and 140 °C. • Excellent stability demonstrated over five consecutive reaction cycles. • In situ IR confirms cooperative mechanism at Co-O-Ce active centers and O V . The direct conversion of carbon dioxide (CO 2 ) and methanol (CH 3 OH) into dimethyl carbonate (DMC) represents a highly attractive route for sustainable chemical synthesis and carbon utilization. However, when operating without dehydrating agents (typically used to shift the thermodynamic equilibrium), the process faces a fundamental challenge on conventional CeO 2 -based catalysts: the competitive adsorption of CO 2 and CH 3 OH for similar active sites, which ultimately limits reaction efficiency. To address this challenge, an innovative strategy was developed through the design of defect-engineered Co 0.05 Ce 0.95 O 2-δ solid solutions. Comprehensive characterization using Raman spectroscopy, XPS, XANES and EXAFS spectra, and AC-TEM confirmed the successful incorporation of Co into the CeO 2 lattice. The incorporation of Co generated abundant oxygen vacancies (O V ) and unique Co-associated interfacial sites (Co-O-Ce). These sites collectively enhanced the catalyst's acidity and basicity and helped alleviate competitive adsorption. Specifically, Co-O-Ce sites are proposed to favor CH 3 OH adsorption and activation, while O V and adjacent Ce ions facilitate CO 2 adsorption and polarization. This cooperative interaction substantially enhances the reaction efficiency, enabling the catalyst to achieve a high DMC formation rate of 16.5 mmol·g −1 ·h −1 under mild conditions (140 °C, 2 MPa), which surpasses that of most reported CeO 2 -based catalysts under comparable conditions. Moreover, the catalyst exhibited outstanding stability over five consecutive cycles. The reaction mechanism, involving the synergistic function of the Co-O-Ce interface sites, was further validated by in situ infrared spectroscopy. Beyond providing a highly efficient and stable catalyst, this work offers fundamental insights into active site engineering for promoting cooperative activation in CO 2 conversion reactions.
