Monitoring dopamine (DA) in pork can provide useful information for assessing meat freshness and quality deterioration. In this work, an Fe@N-S-O-C nanocomposite was fabricated as an electrode modifier for DA determination. The Fe@N-S-O-C nanocomposite was synthesized via precipitation followed by calcination using melamine and ferrous sulfate as precursors. The crystal structure, surface chemical composition, and morphology were characterized by XRD, XPS, SEM, and TEM. The Fe@N-S-O-C-modified glassy carbon electrode (Fe@N-S-O-C/GCE) was then evaluated for its electrocatalytic performance toward DA. Under the optimized conditions (pH 6.0), the sensor showed linear responses to DA over 1–65 and 65–220 μM. The sensitivities for these two ranges were 4.357 and 1.685 μA μM−1cm−2, respectively, with an LOD of 40 nM. In addition, the Fe@N-S-O-C/GCE showed excellent reproducibility, good repeatability, and strong anti-interference capability against common coexisting substances. After 30 days of storage, 82.74% of the initial current response was retained by the same electrode. Practical applicability of the sensor was verified in pork samples, with recoveries of 95.97–106.73%. These results demonstrate that the Fe@N-S-O-C/GCE sensor offers a reliable and effective platform for DA detection in complex food matrices.

Both inorganic solid electrolytes and organic polymer solid electrolytes face limitations in practical applications due to their shortcomings. Inorganic solid electrolytes suffer from high interface impedance and poor mechanical properties, while polymer solid electrolytes struggle with low Li-ion conductivity, thermal stability and electrochemical stability. To overcome the drawbacks of single phase solid electrolytes while utilizing their respective advantages, composite solid electrolytes have emerged as a popular research direction in recent years. Typical composite solid electrolytes feature inorganic filler particles dispersed in a polymer matrix. In this work, we introduce a novel non-flammable composite solid electrolyte with inorganic matrix and inorganic fillers. The composite solid electrolyte was prepared by integrating a 3D Si-Zr-O-C inorganic fiber film with Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) particles that have high ionic conductivity via a vacuum impregnation process, which is all-inorganic solid state electrolyte. This unique design of established network structure provides fast Li-ion transport channels, enabling high ionic conductivity (2.3 × 10 −4 S cm −1 at room temperature). Furthermore, the Si-Zr-O-C/LLZTO (SLTO) composite electrolyte also exhibits superior flexibility, thermal stability, and electrochemical stability. The SLTO composite solid electrolyte presents a promising electrolyte candidate for next generation lithium ion batteries.

Bisphenol A (BPA) pollution severely threatens aquatic ecology and human health, and peroxymonosulfate (PMS)-based advanced oxidation processes are efficient for refractory organic pollutant remediation. Our previous study realized the in-situ synthesis of nitrogen-doped swine manure biochar (NBC) for enhanced PMS catalysis, yet abundant endogenous silicon in swine manure remains inert as SiO 2 and fails to contribute to catalysis, restricting the full resource utilization of livestock waste. Targeting this bottleneck, we herein develop a facile ball-milling coupled with HF etching strategy to activate intrinsic silicon on NBC without exogenous dopants. This approach converts inert SiO 2 into reactive Si–O–C interfacial sites while preserving the original nitrogen-doped carbon framework, yielding a Si modified biochar (Si-NBC). Benefiting from the synergistic effect of Si–O–C bridges and inherent nitrogen active sites, the optimized Si-NBC achieves 98% BPA removal within 20 min and 42% total organic carbon mineralization, with a rate constant 18-fold higher than pristine NBC. It performs robustly across pH 3–9, tolerates common coexisting anions, and maintains removal above 90% for 72 h in a continuous-flow reactor. Mechanistic investigations reveal a synergistic non-radical regime: singlet oxygen, generated at C–C and graphitic N sites, dominates the oxidative process, while an electron-transfer pathway, mediated by graphitic N and Si–O–C bridges, accelerates interfacial charge shuttling. Degradation intermediates exhibit markedly reduced ecotoxicity compared to parent BPA. By leveraging in-situ interfacial engineering of biomass-derived carbons, this work both valorizes the underutilized silicon in livestock waste and establishes a mechanistic rationale for the design of high-performance, eco-friendly PMS catalysts.

The key to the development of metal–air batteries is the research on efficient and stable non-noble metal bifunctional electrocatalysts that can simultaneously catalyze the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in the same electrolyte. Ce–O–C single-component materials have abundant oxygen vacancies and commendable electrical conductivity; therefore, they have great application potential in bifunctional catalysis. However, their application is limited by the harsh synthesis conditions (pyrolysis at >1750 °C). Herein, CeO2C2/NC material is obtained during the pyrolysis of Ce-MOF at 900 °C, and it is found that the CeO2C2/NC material has a satisfactory ORR/OER bifunctional catalytic effect. In addition, CeO2C2/NC possesses good electrochemical properties, such as ORR Eonset = 0.92 V, E1/2 = 0.83 V (vs reversible hydrogen electrode (RHE)), and an excellent Tafel slope of 77.7 mV dec–1, outperforming the commercial Pt/C catalyst. X-ray photoelectron spectroscopy (XPS) analysis reveals that Ce3+ and its chemisorbed oxygen (Oβ) percentages of 50.33 and 79.37%, respectively, are the main reasons for the production of abundant oxygen vacancies. The prepared Ce–O–C series material will be applied to zinc–air batteries (ZABs), which is expected to improve the comprehensive performance of ZABs. The results can provide ideas for the development of ORR/OER single-component bifunctional catalysts.

Manganese-based oxides are promising cathodes for aqueous zinc-ion batteries but often suffer from structural instability, manganese dissolution, and poor conductivity. Herein, we propose a "dual-network synergistic construction" strategy through the in-situ derivation of a metal–organic framework to concurrently address these challenges. This strategy ingeniously constructs an oxygen-deficient network and a conductive carbon network within a hierarchical Mn₂O₃/C composite (O d -Mn₂O₃/C-400). The formed interfacial Mn–O–C bonds effectively enhance structural integrity and regulate the concentration of oxygen vacancies. As a cathode for aqueous zinc-ion batteries, the O d -Mn₂O₃/C-400 composite demonstrates exceptional electrochemical performance, delivering a remarkable specific capacity of 425 mAh·g⁻¹ at 3 A·g⁻¹. More importantly, it exhibits outstanding long-term cyclability, retaining 87.67% of its capacity (174 mAh·g⁻¹) after 5,000 cycles at a high current density of 5 A·g⁻¹. When configured into a zinc-ion hybrid supercapacitor (O d -Mn₂O₃/C-400//AC), the device achieves a high energy density of 119 Wh·kg⁻¹ at 189 W·kg⁻¹, and maintains 78.6% capacity retention with 97.5% Coulombic efficiency over 3,000 cycles. This work provides an effective material design paradigm for developing high-performance manganese-based electrodes for advanced energy storage systems.

Ceramic parts with complex structures can be manufactured by three-dimensional (3D) printing technology. However, the ceramic raw materials available for 3D printing are very limited. This paper mainly focuses on the selection, composition, and proportion optimization of ceramic precursor systems. The optimal photoinitiator was selected by comparing the ultraviolet absorption bands of 2,2-dimethoxy-2-phenylacetophenone), diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, and bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide (819) photoinitiators. In addition, the effects of different photoinitiators on system reactions and curing efficiency were considered, and the content of photoinitiators was optimized based on actual conditions. The mercapto-to-vinyl ratio was optimized to obtain Si-O-C-based ceramic raw materials that could be used for photo-curing 3D printing by comparing the ceramic yield, size shrinkage, and mechanical properties.

Introducing two-dimensional (2D) nanoreinforced materials on the surface of carbon fibers (CFs) is a promising strategy for overcoming the chemical inertness of CFs. However, disordered alignment and uneven dispersion of 2D nanoreinforced materials on the CF surface are the most critical issues that must be addressed. Herein, MXene (M) was functionalized using graphene oxide (G) to produce intercalated 2D reinforcement materials, and robust Ti–O–C covalent bonds were introduced to ensure that M and G have strong binding forces. An interface layer with a more ordered and compact “brick-and-mortar” structure was developed on the CF surface to obtain CF composites with high strength and toughness. Owing to the structure superiority, robust Ti–O–C covalent bonding, and abundant π–π interactions, the optimal CF composites achieved high strength and toughness, with a tensile strength of 1587 MPa and a toughness of 45 MJ m–3. Meanwhile, the interlaminar shear and flexural strengths increased to 82 and 1178 MPa, respectively. The reinforcing mechanisms of the unique interface layer on CF composites were systematically investigated via data analysis and modeling. This study provides a constructive design inspiration for fabricating high-performance CF-reinforced polymer composites, considerably expanding their applications.

A rapid, sensitive, and convenient surface-enhanced Raman spectroscopy (SERS) substrate was developed using Fe₃O₄/C as the magnetic core and SiO₂-SH as the shell for the detection of aflatoxin B1 (AFB1). Ultra-small Fe₃O₄/C nanoparticles (NPs) with an average size of 6.30 ± 0.68 nm and excellent magnetic responsiveness were synthesized via a one-pot hydrothermal method, followed by the deposition of a uniform SiO₂ shell, followed by thiol-group functionalization to yield Fe₃O₄/C/SiO₂-SH. The magnetic core enables instantaneous separation of the substrate from solution after AFB1 adsorption, eliminating the need for centrifugation or filtration. When employed as a SERS substrate, significant enhancement of the characteristic Raman peak at 1482 cm⁻ 1 was observed across AFB1 concentrations of 0.1–10 μg/mL. Notably, the peak intensity at 10 μg/mL exceeded that of solid AFB1 powder. Comprehensive characterization (TEM, XRD, FTIR, XPS, and vibrating sample magnetometry) confirmed the core–shell structure, high crystallinity, and strong magnetic properties. The prepared Fe₃O₄/C/SiO₂-SH nanocomposite offers a low-cost, easily recyclable, and noble-metal-free platform, demonstrating strong potential for trace AFB1 monitoring in herbal medicines and food products.

Silicon oxycarbide (SiOC)-based materials hold significant potential as anodes of lithium-ion batteries (LIBs) due to their high theoretical capacity, low volume expansion, and excellent electrochemical stability. However, they exhibit low initial Coulombic efficiency (ICE) and poor cycling stability. In this study, carbon/silicon oxycarbide (C/SiOC) composites were synthesized using a facile sol-gel method followed by ambient pressure drying and thermal treatment. The phase composition of SiOC was tuned by the oxygen content of precursors to achieve a high content of reversible phase for Li storage. Among four organosilanes including trimethylethoxysilane (TMES), 1,3,5,7-tetramethylcyclotetrasiloxane (TMCTS), methyltriethoxysilane (MTES), and tetraethoxysilane (TEOS), TMCTS leads to the highest content of SiO 3 C and SiO 2 C 2 phases owing to moderate oxygen content, which are responsible for Li storage. Hence, the C/SiOC composite with TMCTS as precursor exhibits significantly higher initial Coulombic efficiency (70.53%) than those with TMES, MTES, and TEOS as precursors (68.86%, 43.85%, and 33.11%), which this value exceeds the typical ICE range of 50–60% reported for other SiOC-based materials. It was demonstrated that a higher oxygen content of the precursor promotes the generation of Li 2 O during the lithiation process, which acts as a robust structural buffer to enhanced structural stability. TMCTS-derived C/SiOC composite exhibited excellent cyclic stability over long-term cycling, retaining 601.87 mAh·g −1 after 100 cycles at 0.1 A·g −1 . The results verify the critical role of phase composition of SiOC as anodes of LIBs, providing a new strategy to design SiOC-based materials with high electrochemical performance by tuning phase composition of SiOC from its precursor.

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.

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.

Encapsulation is a crucial technology for isolating and protecting moisture-sensitive materials. However, traditional organic-inorganic composite films often exhibit poor adhesion at the interface and high gas permeability, making stable operation difficult. In this work, an enhanced atomic layer deposition (EALD) method was used to uniformly deposit a layer of thickness-controlled alumina on a Polyethylene Naphthalate (PEN) film with oxygen-containing polar groups(CTPEN) on its surface, successfully producing a high-barrier composite film (EALD-Al 2 O 3 /CTPEN) with Al-O-C chemical bonds. The designed CTPEN film significantly enhanced the adhesion of alumina, thereby improving the performance of the composite film. Moreover, the mechanical properties of the composite film were significantly enhanced, with the elongation at break of EALD-Al 2 O 3 /CTPEN at 72 % being considerably higher than that of ALD-Al 2 O 3 /PEN at 44 %, and the tensile strength reaching 220 MPa. At the same time, EALD-Al 2 O 3 /CTPEN maintained excellent light transmission, exceeding 85 %. Humidity -sensitive resistors encapsulated with EALD-Al 2 O 3 /CTPEN exhibited stable operating performance in both air and humidity-sensitive environments, confirming the superior barrier properties of the composite film. This EALD-Al 2 O 3 /CTPEN composite layer holds promise as a prospective encapsulation layer for future flexible devices.
