Non-noble metal single-atom catalysts with high catalytic activity have garnered considerable attention from researchers in recent years. Yet, their synthesis is affected by various factors, making process optimization a challenging and systematic task. In this study, single-atom Fe–N–C porous hollow microspheres were successfully synthesized via ultrasonic spray pyrolysis, with machine learning employed to optimize the fabrication process. Machine learning models, trained on pre-experimental data, identified the key factors influencing material structure and oxygen reduction reaction (ORR) performance. The resulting Fe–N–C (600–900) material demonstrated excellent ORR activity with a half-wave potential of 0.865 V, along with high stability and methanol tolerance. When applied to traditional liquid zinc–air batteries (ZABs), it achieved an open-circuit voltage of 1.56 V and a maximum power density of 313.4 mW cm–2, with a discharge capacity of 806.5 mAh gZn–1 at 10 mA cm–2, outperforming commercial noble metal catalysts. This work offers valuable insights into the application of machine learning for optimizing ORR catalysts and designing high-performance materials for energy conversion devices.

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.

Polytetrafluoroethylene (PTFE) is renowned for its exceptional chemical inertness and hydrophobicity. However, the high melt viscosity, low surface energy, and high cooling shrinkage of PTFE make it difficult to fabricate fine three-dimensional (3D) structures through photopolymerization molding. Meanwhile, due to the mechanical properties of PTFE, such as low hardness and low elastic modulus, the wear resistance of its structure is usually poor. In this study, we propose an effective strategy to enhance both wear resistance and superhydrophobicity in 3D-printed PTFE/C structures by controlling the carbon residue during the sintering process. To achieve the refined structure of PTFE, a photo-cross-linkable PTFE/PEGDA ink was developed, in which PEGDA acts as a photocurable scaffold to enable high-resolution DLP printing of PTFE nanoparticles. Furthermore, inspired by the microarray of cicada wings, a needle-repellent structure with a water contact angle (CA) exceeding 150° was printed using a PTFE-based ink. Based on the above structure, the carbon residue in PTFE/PEGDA was controlled by the sintering process to further enhance the wear resistance and superhydrophobicity of the structure. These results indicated that the sintered needle-repellent structure can still maintain excellent hydrophobic properties with 1000-grit sandpaper under a load of 100 g for 20 cycles. The performance conflict between superhydrophobicity and wear resistance of the PTFE/C structure has been effectively alleviated through the printed needle-repellent structure and controlled carbon residue. Furthermore, even after 2 weeks of immersion in strongly acidic and alkaline environments, the structure morphology remains stable. These excellent features of the needle-repellent structure make it applicable to a wide range of applications, such as droplet manipulation, oil–water separation, and fog harvesting.

Due to the high energy conversion efficiency and environmental friendliness, proton exchange membrane fuel cells (PEMFCs) have attracted significant attentions for advancing clean energy technologies. However, the sluggish kinetics of the cathodic oxygen reduction reaction (ORR) severely limits the performance of PEMFCs. The high cost and poor durability of platinum-based electrocatalysts necessitate the development of alternative low-cost transition metal and N co-doped carbon (TM-N-C) catalysts. Nevertheless, the ORR activity of TM-N-C is limited by the low density of exposed active sites TM-N x on carbon. Herein, a combined high internal phase emulsion (HIPE) soft template and ZnO hard template is developed to fabricate porous Fe and N co-doped carbon (HP-Fe-N/C) catalyst. This coupled soft-hard template approach enables the construction of a hierarchical porous structure with high exposure of Fe-N x active sites and significantly promoted mass transport during ORR. The resultant HP-Fe-N/C demonstrates superior ORR electrocatalytic activity, achieving a high half-wave potential of 0.75 V in 0.1 M HClO 4 and 0.89 V in 0.1M KOH aqueous solution. When applied as a catalyst for the cathode of PEMFCs, the HP-Fe-N/C delivers a remarkable peak power density of 528.4 mW cm -2 and a high retention rate of 88.5% of its initial current density after working for 10 hours. This work provides a new approach for the fabrication of well-controlled hierarchical porous carbon-based electrocatalysts for the PEMFC.

BACKGROUND Bactrocera dorsalis (Diptera: Tephritidae) is a highly adaptable invasive pest that causes significant economic losses. Long-term chemical control strategies have led to high levels of insecticide resistance and severe environmental risks. C-type lectins (CTLs), key pattern recognition receptors in insect innate immunity, are named for their calcium-dependent carbohydrate recognition domains (CRDs) and they play a critical role in detecting and binding to foreign pathogens. This study aims to identify B. dorsalis CTLs (BdCTLs) and investigate their roles in pathogen defense. RESULTS A total of 42 BdCTL genes were identified. Based on the number of CRDs, 36 genes were classified into the S subfamily, while the remaining six were assigned to the X subfamily. Spatio-temporal expression analysis by qPCR revealed that BdCTL genes were expressed throughout all developmental stages with a higher expression observed in the midgut, Malpighian tubules, and fat body. The expression levels of BdCTL-S4 , BdCTL-S12 , and BdCTL-S31 were significantly upregulated under the infection of the entomopathogenic fungus Beauveria bassiana . Notably, BdCTL-S12 also exhibited upregulated expression patterns in response to four different pathogens bacteria with sustained expression over time. Using RNA interference (RNAi), we successfully knocked down BdCTL-S12 expression, achieving a silencing efficiency of 68%. Survival assays demonstrated a 10–30% reduction in the survival rate of B. dorsalis after pathogen infection following dsRNA injection compared to the control group. Further in vitro experiments confirmed that BdCTL-S12 can agglutinate and bind to pathogens in a calcium-dependent manner. This binding was competitively inhibited by polysaccharides, underscoring a key functional mechanism of BdCTL-S12 in pathogen recognition. CONCLUSION In summary, we identified 42 BdCTLs and demonstrated that BdCTL-S12 is critical for pathogen recognition and immune defense in B. dorsalis . These results advance our understanding of the molecular mechanisms underlying B. dorsalis immunity. Specifically, elucidating the role of CTLs may facilitate the development of microbial-based biological control strategies (e.g., entomopathogenic fungi or bacteria) against this invasive pest. Additionally, RNAi-mediated knockdown of CTL-encoding genes could weaken the immune system of Bactrocera flies, increasing their susceptibility to microbial infections and thereby enhancing the effectiveness of biological control. © 2025 Society of Chemical Industry.

The activation of C–H bonds is a fundamental process in various chemical reactions, while faces significant challenge under mild conditions due to the high bond energy and low polarity. An ultrathin (∼3 nm) amorphous oxygen-containing carbon layer inserted into Pt/TiO 2 yields C–O–M (M = Pt and Ti) dual interfaces. The photothermocatalytic consumption rate of n -heptane over Pt/C/TiO 2 at 140 ℃ is 8.8 and 61.8 times higher than that over Pt/TiO 2 and Pt/C, respectively. Temperature-programmed desorption (TPD) and density functional theory (DFT) calculations reveal that the constructed C–O–M interfaces significantly enhance the adsorption of hydrocarbon reactant, and decrease the C–H bond scission energy barrier. The photothermal X-ray photoelectron spectroscopy (XPS), femtosecond transient absorption (fs-TA) and electron paramagnetic resonance (EPR) experiments demonstrate that the C–O–Ti interface accelerates the electron migration and transforms the adsorbed oxygen into the superoxide species, thus efficiently oxidizing the reactant. Furthermore, introduction of an amorphous carbon layer to Pt/Al 2 O 3 , Pt/CeO 2 , Ce/TiO 2 or Cu/TiO 2 remarkably enhances the photothermal catalytic performance for propane, pentane, octane, toluene or hexanal oxidation. The unique effect of C–O–M dual interfaces induced via the ultrathin amorphous carbon layer provides a guideline for designing catalysts with efficient C–H bond activation ability.

Transition metal-carbon compounds derived from Ni-MOFs show promise as catalysts for the hydrogen evolution reaction (HER) water electrolysis but suffer from limited reactivity and stability. Elemental doping is a key strategy to enhance both catalytic activity and durability. Here, we present an effective approach to simultaneously improve catalyst performance and structural robustness by in-situ doping a Ni-MOF precursor with La. Using a La-doped nanoflower-structured NiLa-MOF precursor as a self-sacrificing template, we obtained a highly active and stable nanoflower-like NiLa-Ni 2 P/C electrocatalyst via pyrolysis and phosphidation.Uniform La doping into the MOF precursor not only promotes nanoflower-like morphology formation and enhances stability, but also tunes the electronic structure of Ni active centres, markedly improving catalytic reactivity. Consequently, the NiLa-Ni 2 P/C catalyst delivers exceptional HER performance: only 167 mV overpotential and 90 mV·dec −1 Tafel slope at 10 mA·cm −2 in 1.0 M KOH. It also shows superior long-term stability over undoped Ni-Ni 2 P/C at the same current density. This work provides new insights and practical strategies for rare-earth-element-based HER catalysts in alkaline water electrolysis.

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.

Zero-valent iron (ZVI) technology is regarded as one of the most efficient approaches for remediating groundwater contaminated with chlorinated hydrocarbons (CHCs). Despite its highly reactive nature, the corrosion of ZVI in aqueous solution readily results in surface passivation, which diminishes its reactivity. ZVI doped with heteroatoms such as carbon (C), nitrogen (N), and sulfur (S) has displayed excellent performance in trichloroethylene (TCE) degradation. Nevertheless, the effects of these heteroatoms on ZVI materials, along with their various degradation mechanisms, remains ambiguous. In this study, C-mZVI bm , N-mZVI bm , and S-mZVI bm were prepared, respectively, via a mechanochemical method and utilized for TCE degradation. The dechlorination reaction facilitated by each material was thoroughly investigated both theoretically and experimentally, focusing on TCE adsorption affinity, the dechlorination process, hydrogen evolution reaction (HER), electron efficiency, and lifetime. Among the three materials, S-mZVI bm exhibited 100% TCE removal in less than 24 h., as well as improved electron efficiency and lifetime, primarily attributed to its high TCE adsorption energy and the suppression of HER. These integrated theoretical and experimental results indicate that S-mZVI bm nanoparticles are a promising and innovative material for in situ groundwater TCE remediation.

Silicon suboxide (SiOx, 0 < x < 2) is a promising anode material for lithium-ion (Li-ion) batteries due to its high theoretical capacity, yet the application of SiOx anodes is limited by their low electrical conductivity and drastic volume expansion. Although integrating SiOx nanoparticles with carbon materials can mitigate these issues, achieving both uniform dispersion of SiOx nanoparticles within the carbon matrix and structural stability remains a significant challenge when using only conventional mechanical mixing, surface coating, and sol–gel methods. Herein, a combined sol–gel and soft-templating method is employed to encapsulate mesoporous SiOx@carbon (SiOx@C) spheres (m-SiOx@CS) within a three-dimensionally ordered macroporous carbon (3DOMC) framework, yielding a nanocomposite (3DOMC/m-SiOx@CS). In m-SiOx@CS, the uniformly dispersed SiOx nanoparticles and carbon provide abundant conductive interfaces to enhance reaction kinetics, and the mesoporous structure enables rapid mass transfer. Meanwhile, 3DOMC provides a stable skeleton to ensure the structural stability of the electrode during cycling. As a result, the 3DOMC/m-SiOx@CS electrode exhibits excellent electrochemical performance and cycling stability, maintaining a high reversible capacity of 488.1 mAh g–1 after 2000 cycles at 1 A g–1. Furthermore, the assembled 3DOMC/m-SiOx@CS||LiFePO4 Li-ion full batteries can maintain a high capacity of 82.5 mAh g–1 after 1000 cycles at 1 C. This study offers a broadly applicable structural design strategy for high-performance SiOx-based anodes.

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.

Waste graphitization cathode carbon blocks are a type of hazardous solid waste generated during the aluminum electrolysis process, and their proper disposal is a key step in the resource utilization of discarded graphite. This study utilizes the porous “defect advantage” of a cathode carbon block matrix to prepare silicon-doped and asphalt-coated detoxified and purified waste graphitization cathode carbon blocks for use as high-performance silicon/carbon composite anode materials. The results show that the uniformly silicon-doped silicon/carbon composite material features a unique amorphous carbon-encapsulated “locked silicon” structure, which effectively addresses issues such as cathode volume expansion, excessive growth of the solid electrolyte interphase (SEI) film, and poor electrical contact between active materials. Consequently, electrochemical performance is enhanced. After assembly in a half-cell, the PSCC/10%Si@C (purified waste graphitization cathode carbon/10%Si@C) material exhibits optimal electrochemical stability, with an initial charging specific capacity of 514.5 mAh/g at 0.1 C (1 C = 170 mA/g) and a capacity retention rate of 95.1% after 100 cycles. At a charge rate of 2.0 C, a specific capacity of 216.9 mAh/g is achieved. This technology provides a new pathway for the economical and high-value utilization of waste cathode carbon blocks and the development of low-cost, high-performance anode materials.
