Wood, as a natural lignocellulose material with multiscale porosity, serves as an excellent structural matrix for fabricating high-performance or functional composite materials. However, its wider application is severely hindered by inherent drawbacks such as poor dimensional stability and susceptibility to fungal degradation. In this work, we propose an eco-friendly and efficient strategy to fabricate wood-based materials with strong and long-lasting resistance to deformation and biodeterioration, aiming to promote the high-value utilization and sustainability of wood. A novel quaternary ammonium-functionalized waterborne epoxy resin (QWEP), featuring nanoscale particle size and high stability, was prepared and effectively infused into the porous structure of wood through vacuum-pressure impregnation. After in-situ curing reaction, the QWEP crosslinked network bearing quaternary ammonium salt (QAS) groups was formed and firmly anchored within the wood. The resulting QWEP modified wood composites achieved favorable dimensional stability and mechanical properties. The anti-swelling efficiency of composites reached 38.1%, while the tensile, flexural, and compressive strength increased by 42.6%, 45.8%, and 79.8%, respectively, compared with unmodified wood. Benefiting from the intrinsic antimicrobial activity of the grafted QAS groups, the composites also demonstrated outstanding antimicrobial efficacy against both bacteria and fungi. After three months of exposure to brown-rot and white-rot fungi, the composites showed an extremely low mass loss (approximately 3.0%) and no visible deformation.

Preparation of γ-Al2O3/Eu-BTC for catalytic sensing toward terpenes. • A cyclic cataluminescence array sensor based on k-values corresponding to terpenes. • Investigation of the k -value pattern on the variation of terpene composition. • Origin identification of 86 hop samples based on characteristic terpenes. Hops are crucial to beer flavor, but their geographically dispersed origins are prone to confusion, while the significant variation in terpene ratios among hops from different regions provides key support for its origin identification. In this study，γ-Al 2 O 3 /Eu-BTC composite was synthesized for cyclic cataluminescence array sensor to terpenes. The results showed that the corresponding reaction decay coefficients ( k -values) for myrcene, farnesene, and humulene were 24.3, 32.0, and 73.8, respectively, enabling terpene-specific fingerprinting. Binary and ternary terpene mixtures exhibited predictable k -value variations, with relative standard deviations below 9.6%. A rapid detection method for hops identification was developed and successfully applied to 86 samples from six different origins. The method demonstrated both feasibility and accuracy, highlighting its potential as a rapid, simple, and efficient technique for origin identification of hops and other aromatic plants.

A walnut meal-based adhesive was developed via organic-inorganic hybridization. • The adhesive achieved 1.14 MPa wet strength after 63 °C water treatment. • Multiple interactions enhanced cohesion, thermal stability, and durability. The development of bio-based wood adhesive is considered an effective strategy to reduce formaldehyde emissions and their adverse impacts on the environment and human health. In this work, inspired by the organic–inorganic synergistic architecture of natural biomineralized structures, walnut meal (WM) based adhesive with excellent property was developed in the laboratory by introducing 3-aminopropyltriethoxysilane (APTES) modified SiO 2 as a reinforcing phase and glycerol triglycidyl ether (GTE) as covalent crosslinker. Comprehensive characterization, including dry/wet bonding strength, thermal stability, water resistance, and mildew resistance tests, demonstrated that the optimal dry bonding strength of plywood produced with WM-based adhesive was 1.76 MPa and 1.14 MPa wet bonding strength after immersion in water at 63 °C for 3 h. Meanwhile, the mass retention of the cured adhesive could reach 85.65% after being treated under the same conditions. Moreover, the cured adhesive exhibited excellent thermal stability and mildew resistance, with a char residue of 40.87% at 600 °C and no obvious mildew growth after 24 days of storage. This biomimetic strategy provides a new approach for the high-value utilization of walnut meal and the development of green, formaldehyde-free wood adhesives.

Achieving efficient charge transfer and separation relies on constructing effective electron-transfer channels tailored to composite photocatalysts. Herein, an S-scheme heterojunction was constructed between g-C 3 N 4 and covalent triazine frameworks (CTFs) to establish a directional internal electric field (IEF). The effects of donor (D) chain extension and increased acceptor (A) number on intramolecular electron transport was conducted. DFT calculations and photoelectrochemical tests indicated that, with the stepwise structural evolution from A1-D-A1 (CTF-1) to A1-D-D-A1 (CTF-2) and further to A1-D-A2-D-A1 (CTF-Azo), the electron density within the CTFs framework gradually increased. When integrated into the S-scheme heterojunction, this concerted structural engineering created an electron-rich interface that efficiently channeled electrons to adsorbed oxygen, yielding a 1.89-fold enhancement in·O 2 − generation compared to g-C 3 N 4 . This rational design enabled 1 wt% CTF-Azo/g-C 3 N 4 to achieve 92% degradation of Levofloxacin (LVX) within 120 min under visible light irradiation and demonstrated a 2.61-fold improvement over g-C 3 N 4 along with deep mineralization. A plausible photocatalytic degradation pathway was proposed, and toxicity evaluation confirmed a reduced ecological risk of the generated intermediates. Moreover, 1 wt% CTF-Azo/g-C 3 N 4 demonstrated robust performance in various complex water systems, highlighting its practical potential. This work demonstrates that orchestrating D-A molecular motifs with S-scheme heterojunctions offers a powerful paradigm for precision electron steering toward efficient antibiotic photodegradation.

Photothermal conversion of CO 2 to methane offers a promising pathway for simultaneous carbon recycling and renewable energy storage. To date, Ni-based catalysts dominate CO 2 methanation. However, their low-temperature activity under photothermal conditions still requires improvement. MTiO 2 derived from Ti 3 C 2 MXene retains its two-dimensional (2D) layered structure and excellent photothermal conversion properties. Herein, we synthesized Ru-Ni@MTiO 2 catalysts through hydrothermal treatment of Ni-impregnated MTiO 2 with controlled Ru loading ( x = 1, 3 and 5 wt%). The optimal 3Ru-Ni@MTiO 2 catalyst achieved a CH 4 production rate of 86.25 mmol·g −1 ·h −1 at 300 °C, which is 1.3-fold higher than that of the Ru-free Ni@MTiO 2 counterpart. The superior catalytic performance stems from the synergistic electronic effect between Ni and Ru and their dual-site cooperation. Electron transfer from both Ru and MTiO 2 to Ni sites elevates the electron density of metallic Ni, which weakens the H-H bond and accelerates the dissociative adsorption of H 2 . Furthermore, Ru loading not only broadens the light absorption range and promotes photogenerated charge separation, but also increases the density of moderate basic sites, thus boosting CO 2 adsorption and activation. This work provides new insights into the design of bimetallic photothermal catalysts for CO 2 methanation.

Carbon fabric (CF)-reinforced polymer composites show great potential in wet friction applications, but their performance is severely limited by poor interfacial adhesion and susceptibility to abrasive wear. Herein, we propose a “rigid-flexible” hierarchical interface strategy utilizing a conformal defect-filling carboxymethyl cellulose (CMC) layer and an in-situ grown rigid UiO66-NH 2 octahedral array to enhance the mechanical and tribological properties of CF/phenolic composites. The CMC/UiO66-NH2 hierarchical modification reduced surface defects and increased the apparent single-fiber tensile strength by 89.3%. Meanwhile, the UiO66-NH 2 array increased the surface roughness and promoted mechanical interlocking with the resin matrix. The combined CMC/UiO66-NH 2 interface improved interfacial load transfer and reduced premature debonding, leading to a 75.1% increase in tensile strength. Furthermore, under alternating friction shear, the hierarchical interface promotes the formation of a protective tribofilm, promoting the in-situ formation of a continuous solid tribofilm. This transitions the wear mechanism from severe abrasive wear to mild sliding wear, resulting in an 81.1% reduction in the specific wear rate. This study provides an interfacial design strategy for designing high-load-bearing and highly durable fabric composites for demanding tribological applications.

Co Fe dual single-atom sites tailor electronic structure to boost PMS activation. • 97.7% ± 2.6% tetracycline removal in 15 min ( k = 0.22 min −1 ), outperforming single-atom catalysts. • Fixed-bed reactor sustains ∼95% tetracycline removal for 120 h with lower ecotoxicity. Single-atom catalysts (SACs) for peroxymonosulfate (PMS) activation are often constrained by the limited electronic tunability of isolated mono-metal centers, which weakens oxidant adsorption and interfacial charge transfer. Herein, we overcome this limitation by constructing a Co Fe dual single-atom catalyst anchored on a nitrogen-doped carbon aerogel (Co–Fe/NCNA) for visible-light-assisted tetracycline degradation. Spectroscopic and synchrotron analyses confirm that atomically dispersed Co N 3 and Fe N 4 sites coexist within a hierarchically porous three-dimensional carbon framework, ensuring high active-site accessibility and rapid mass transport. The Co–Fe/NCNA system achieves 97.7% ± 2.6% tetracycline (TC) removal within 15 min ( k = 0.22 min −1 ), dramatically outperforming single-metal and metal-free analogues. Density functional theory calculations indicate that the coupled Co Fe sites reconstruct the local electronic structure, elevate the d-band center, strengthen PMS adsorption, and reduce the activation barrier for PMS conversion to 0.30 eV. The TC degradation proceeds through a cooperative radical/nonradical oxidation network, in which h + -mediated oxidation acts as the primary apparent pathway, while 1 O 2 , ·O 2 − , ·OH, SO 4 · − , and possible high-valent metal-oxo-like species contribute synergistically or serve as auxiliary pathways. Notably, a fixed-bed continuous-flow reactor sustains ∼95% tetracycline removal over 120 h, and outstanding activity is retained under natural sunlight. This work establishes electronic structure engineering of dual single-atom sites as a powerful strategy to boost visible-light-driven PMS activation for sustainable water remediation. Under visible-light irradiation, the Co Fe dual single-atom sites regulate the local electronic structure, optimize the d-band center, and promote photogenerated charge separation and interfacial electron transfer, thereby enabling efficient peroxymonosulfate (PMS) activation. Through the synergistic cooperation of electron-mediated PMS reduction, hole-mediated PMS oxidation, and Co/Fe self-cycling, radical and non-radical reactive species are generated to construct an integrated oxidation network, which drives the efficient degradation and mineralization of tetracycline.

Driven by carbon neutrality and petroleum depletion, renewable bio-based composites with environmental durability are urgently needed. However, the inherent hydrophilicity of agricultural waste and the poor durability/formaldehyde emission of traditional surface modifications limit engineering applications. This study proposes a “top-down” interfacial engineering strategy to resolve biomass–hydrophobic particle compatibility, achieving inherent hydrophobicity without adhesives. Using absolute ethanol as a low-polarity carrier, silane-modified hydrophobic silica (SiO₂) was uniformly dispersed in wheat straw fibers, with cationic starch as an interfacial bridging agent. The effects of SiO₂ particle size (30 nm–30 μm) and addition level (10%–50%) on morphology, mechanics, and wetting were investigated. With 30 nm SiO₂ at 25% (N30–25), the board achieves superhydrophobicity (water contact angle 150°, sliding angle 15°) and high bending strength (22.08 MPa), balancing hydrophobicity and reinforcement. Mechanistically, cationic starch forms a 3D cross-linked network via electrostatic attraction and hydrogen bonding. The nano-SiO₂ and micro-fiber bundles create a micro/nano hierarchical rough structure that traps air to form a stable Cassie-Baxter air cushion. Environmental durability tests confirm the bulk hydrophobic network remains stable under mechanical abrasion, water erosion, and UV aging. This work provides a theoretical basis for high-value agricultural waste utilization and a pathway for durable, eco-friendly green composites.

Motivated by gas-accessible thin liquid films in lung alveoli, we develop gas marble-film reactors in which particle-stabilized bubbles confine an ultrathin freestanding liquid film within a jammed solid shell. Hexagonal PET (poly(ethylene terephthalate)) plates, in addition to conventional spherical particles, generate faceted gas marbles with planar film regions that improve optical access. We quantify the pressure limits of microsphere- and plate-stabilized shells during inflation and deflation, and describe their response using a capillary–granular framework. In this framework, inflation rupture is governed by capillary breakthrough at particle-defined throats, whereas deflation collapse reflects the combined resistance of capillarity and interparticle jamming. The mechanically defined films then serve as gas-accessible interfacial reactors in two proof-of-concept demonstrations. In a Tollens reaction, aerosolized glucose delivery through the external gas phase localizes silver reduction to liquid-wetted regions of the particle shell, producing spatially patterned silver-deposited microspheres. In biological assays, plate-stabilized shells provide flat observation windows for monitoring aerobic E. coli growth and its inhibition by levofloxacin. These results establish gas marbles as programmable colloidal film reactors whose structure, pressure stability, and interfacial function can be coupled through particle geometry and capillary jamming.

Replacing α -hydroxyl group with an α , β -unsaturated group markedly enhanced the decomposition reactivity of dimer. • α , β -Unsaturated group promoted C α ─C β bond cleavage, while α -hydroxyl group led to β -O-4 bond cleavage. • α , β -Unsaturated group accelerated reaction rate ∼14-fold at 120 °C. • Dehydration of α -hydroxyl group into α , β -unsaturated group facilitated lignin depolymerization. Lignin is a promising feedstock for the production of monomeric aromatics, which can be further upgraded into valuable chemicals or fuel hydrocarbons. In this work, the effect of the α , β -unsaturated group on the conversion of lignin and its β -O-4 model dimers into monomeric aromatics was investigated. The results showed that replacing the native α -hydroxyl group with an α , β -unsaturated group markedly enhanced the decomposition reactivity of the dimer. Specifically, the α , β -unsaturated group promoted C α ─C β bond cleavage, whereas the native α -hydroxyl group led to β -O-4 bond cleavage. This significant enhancement in reactivity was consistent across varied reaction conditions and enabled near-quantitative yields of monomeric aromatics from the dimer containing the α , β -unsaturated group. Kinetic analyses indicated apparent first-order kinetic behavior for both dimers, showing that the α , β -unsaturated group accelerated the reaction rate by a factor of approximately 14 at 120 °C. Moreover, an α , β -unsaturated group generated in situ via dehydration of the α -hydroxyl group during pretreatment effectively facilitated lignin depolymerization. This work outlines a promising approach for developing efficient lignin depolymerization technologies targeting monomeric aromatics.

The dielectric–magnetic synergy and interfacial engineering is an important methodology to boost electromagnetic wave absorption performance. We herein propose a novel “coating-ion exchange etching-high temperature carbonization” process to synthesize yolk–shell zinc oxide/carbon@air@cobalt-nickel alloy (ZnO/C@air@CoNi) nanocages by taking advantages of dielectric–magnetic synergy and interfacial effect. The bimetallic core–shell ZIF-8@ZIF-67 precursor is employed as the structural template while Ni(NO₃)₂·6H₂O as an etchant to ensure controlled ion-exchange etching. The resulting dielectric zinc oxide/carbon (ZnO/C) core promotes interfacial polarization and dipole reorientation losses, while the CoNi shell enhances conductive loss and magnetic loss. Thanks to the dielectric–magnetic synergy and interfacial effect, the ZnO/C@air@CoNi nanocomposite exhibits outstanding electromagnetic wave absorption performance, achieving a maximum reflection loss of −72.28 dB and an effective absorption bandwidth of 5.28 GHz (12.40 −17.68 GHz) at a low filler loading of 20 wt%. This work provides new ideas to design absorbers by leveraging the structural versatility of MOF-derived precursors.

A MIP/AuNPs/GCE electrode was constructed for simultaneous detection of CAP and MNZ. • The sensor shows a wide linear range (50–1500 μM) and low LODs of 1.70 and 2.09 μM. • Wavelet transform expands the feature dimensions of the DPV signals to enhance model prediction accuracy. • TPE-optimized XGBoost realizes accurate and robust dual-analyte concentration prediction. • The method achieves satisfactory recoveries in milk, fish, and egg real samples. Food safety concerns have increased the demand for reliable simultaneous detection of chloramphenicol (CAP) and metronidazole (MNZ), as these antibiotics are strictly regulated due to their potential health risks. However, the presence of aromatic nitro groups in both compounds poses a challenge for their simultaneous detection. In this study, an electrochemical sensor integrating electrodeposited gold nanoparticles (AuNPs) with a dual-template molecularly imprinted polymer (MIP) film was developed to achieve selective recognition and signal enhancement for both analytes. However, competitive adsorption at active sites in multi-component systems leads to nonlinear signal responses, rendering traditional linear calibration ineffective. To overcome this limitation, differential pulse voltammetry (DPV) signals were transformed into two-dimensional wavelet spectrograms, from which quantitative image features were extracted, and the necessity and robustness of these features were verified using SHAP analysis. An XGBoost regression model optimized via a Tree-structured Parzen Estimator (TPE) was subsequently constructed, yielding significantly improved predictive performance. The sensor exhibited a wide linear range for both CAP and MNZ (50–1500 μM) and low detection limits (1.70 μM and 2.09 μM, respectively). Satisfactory recoveries (89.37–107.31%) were obtained in spiked milk and fish samples. The proposed TPE-XGBoost-assisted dual-template molecular sensor provides a robust and generalizable strategy for rapid and accurate multi-residue detection in complex food matrices.
