Fused silica (SiO2) exhibits exceptional thermal stability and dielectric properties, making it an attractive material for aerospace and military applications. However, its relatively poor mechanical performance has limited its widespread practical utilization. This study proposed an innovative approach to fabricate SiO2-hexagonal boron nitride (hBN) composite ceramics via spark plasma sintering (SPS), leveraging the high-temperature phase transformation of cubic boron nitride (cBN) to introduce randomly oriented hBN as a reinforcing phase within the SiO2 matrix. The randomly oriented hBN nanoplates allow cracks to propagate along stronger grain boundaries, rather than along weaker interlayers of hBN, significantly improving the overall strength and fracture toughness of the composite. The maximum flexural strength and fracture toughness achieved are 183.4 MPa and 2.06 MPa m1/2 respectively, which are 3.6 times and 4 times that of fused SiO2. Concurrently, the composites exhibit low dielectric constants (ε = 3.58–3.69) and dielectric losses (tan δ < 0.0087) at 1 MHz. This work successfully enhanced the mechanical performance of fused SiO2 while preserving its excellent dielectric characteristics, opening new possibilities for its potential applications in advanced structural and functional fields.

Wound infection is a major cause of death during the wound healing process. Improperly dressed wounds can lead to secondary injury, prolonging healing time and increasing infection risk. Here, we propose an antibacterial slippery dressing through molecular engineering of copper ions. The oil layer forms a barrier to reduce clot adhesion to the wound site and prevent environmental contamination. Single-cell level detection indicates that secreted copper ions induce bacterial death not only by disrupting membrane integrity but also by relying on the production of reactive oxygen species. Further membrane depolarization and adenosine triphosphate production blockage result in the aggregation of important proteins in various biological processes, such as metabolic homeostasis, ultimately leading to bacterial death. The animal model confirms that our dressing accelerates wound healing by promoting the growth of granulation tissue and collagen deposition. Our dressing demonstrates significant clinical implications for the design of next-generation therapeutic applications.

This study investigates the optimization of CO2 mineralization curing on the performance of a ternary cementitious system comprising steel slag, fly ash, and Portland cement. Specimens were fabricated with varying residual water-to-cement ratios (r/w), steel slag and fly ash contents, curing pressures, and durations, then subjected to standard curing and CO2 mineralization curing. Compressive strength and carbon sequestration rate were measured, and X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to analyze mineral composition and microstructural evolution. Results indicate that compressive strength first increases then rapidly decreases with increasing residual water-to-cement ratio, with an optimal r/w below 0.15. Both compressive strength and carbon sequestration rate increase with higher steel slag content; the 50% steel slag + 10% fly ash formulation exhibited the highest values. Microstructural analyses revealed that CO2 mineralization primarily consumes hydration products such as Ca(OH)2, C-S(Al)-H, and AFt, generating abundant calcium carbonate that densifies the pore structure, thereby enhancing mechanical properties. Lower residual water-to-cement ratios, higher steel slag content, or extended curing durations increase the content and crystallinity of calcium carbonate. SEM observations confirmed the presence of densely packed, well-crystallized rhombohedral calcite in specimens with lower water-to-cement ratios and higher steel slag content. These findings provide a mechanistic basis for the engineering application of CO2 mineralization curing in ternary solid-waste cementitious materials.

Low-temperature chemical looping air separation (CLAS) is a promising technology for producing oxygen-enriched gas streams, utilizing the redox properties of solid oxygen carriers to selectively capture and release oxygen from air. Oxygen vacancy formation energy (Eovf) is a key descriptor for evaluating the ease of oxygen release. In this study, the applicable range of Eovf for CLAS oxygen carriers was determined to be <2.3 eV via thermodynamic calculations. A graph neural network (GNN) model, specifically the ALIGNN architecture, was trained to predict Eovf with a mean absolute error (MAE) of 0.26 eV on the test set. Using this model, a high-throughput screening of 3,649 compositions of SrxA1−xFeyB1−yO3 perovskites was conducted to identify promising CLAS oxygen carriers. The predictions revealed that doping with Ba and Ca at the A-site and Co at the B-site effectively reduces Eovf. The screening criterion of Eovf < 2.3 eV successfully rediscovered several previously reported low-temperature CLAS oxygen carriers, validating the approach. This work demonstrates that GNN-based Eovf prediction can significantly accelerate the discovery of CLAS materials, with broader implications for other chemical looping applications such as full oxidation and syngas production.

Rice husk biochar (BC) was modified with boron (B) and nitrogen (N) doping and loaded with Fe3S4 to fabricate B-BC@Fe3S4 and N-BC@Fe3S4 catalysts for peroxydisulfate (PDS) activation and enrofloxacin (ENR) degradation. Characterization via SEM, BET, XRD, Raman, and XPS confirmed successful heteroatom incorporation and uniform Fe3S4 dispersion, enhancing specific surface area and defect sites. Degradation experiments showed that B-BC@Fe3S4 and N-BC@Fe3S4 achieved ENR removal efficiencies of 90.72% and 91.89%, respectively, significantly outperforming unmodified BC@Fe3S4 (82.21%). Mechanistic studies revealed that PDS activation proceeded via Fe3S4-mediated electron transfer generating radical species (SO4•−, •OH, O2•−) and via B/N functional groups promoting non-radical singlet oxygen (1O2) formation. Notably, N-BC@Fe3S4 exhibited superior resistance to Fe3+ leaching and greater environmental adaptability under varying pH, anion, and humic acid conditions. These findings demonstrate that B/N-doped biochar-supported Fe3S4 are effective catalysts for PDS activation, offering promising potential for antibiotic removal from real wastewater matrices.

The selective hydrogenation of biomass-derived furfural (FAL) to high-value chemicals such as furfuryl alcohol (FOL) or tetrahydrofurfuryl alcohol (HFOL) is pivotal yet challenging due to the need for precise control over reaction pathways. In this study, a Ni2Al-LDO (layered double oxide) catalyst with highly dispersed surface NiO was synthesized via structural topological transformation of layered double hydroxides. The catalyst exhibited excellent performance in furfural hydrogenation, achieving a 91.42% yield of FOL at 160 °C and 1.4 MPa H2. Gradual reduction of Ni2Al-LDO produced Ni/NiO mixtures, enabling a tunable shift from FOL to HFOL as NiO content decreased and metallic Ni content increased. After reduction at 700 °C for 2 hours, the HFOL yield reached 93.95% under identical conditions. CO2-TPD, NH3-TPD, and FT-IR analyses revealed that variations in reduction degree influenced furfural adsorption behavior. NiO species selectively adsorb the C=O group of furfural, with isopropanol serving as the hydrogen source via the Meerwein-Ponndorf-Verley (MPV) pathway, yielding FOL. In contrast, metallic Ni0 surfaces facilitate flat adsorption, enabling simultaneous activation of both the furan ring and carbonyl group, and can activate both H2 and isopropanol, with H2 as the primary hydrogen source, leading to complete hydrogenation to HFOL. This work elucidates a clear structure-activity relationship centered on the metal oxidation state and provides a practical reduction-engineering approach for designing adaptable catalysts in biomass upgrading.
