The catalytic upcycling of plastic mixtures into H 2 and carbon nanotubes (CNTs) represents a transformative strategy for advancing plastic management and the circular economy. Herein, an in-situ constructed high-performance FeNi/Ni/C catalyst combined with prompt microwave catalysis enables efficient conversion of LDPE-PVC, LDPE-HDPE-PP-PS-PVC-PTFE and landfilled waste mixture into valuable H 2 and CNTs, resulting in near-quantitative atom economy (i.e., H 2 and carbon efficiencies are nearly 100%) together with H 2 and CNTs yields reaching >922 mmol g -1 catalyst and >10600 mg g -1 catalyst , respectively. Furthermore, this microwave catalysis strategy presents an excellent stability (>35 cycles) via Cl/F-based regeneration and energy efficiency (80% reduction vs. traditional thermal catalysis), alongside a high turnover number of 107.6 mol carbon mol -1 NiFe . Fundamentally, the Ni species contribute to C-H breaking, and Fe is beneficial for CNT formation during plastic decomposition. Here, we show a cost-effective platform for upcycling of chlorinated/fluorinated plastic mixtures, aligning with resource circularity objectives.

BACKGROUND The environmental persistence and resistance-promoting potential of tetracycline demands an efficient catalytic system capable of its complete oxidation. Herein, a bamboo derived Fe-N co-doped activated biochar (designated as Fe-N/C-A-2P) was engineered by two-step synthesis strategy to activate H 2 O 2 in a heterogeneous Fenton system for efficient tetracycline (TC) degradation. RESULTS The catalyst under optimized conditions (catalyst dosage = 0.5 g L −1 , pH = 3, H 2 O 2 concentration = 300 mg L −1 , temperature = 25 °C, and TC = 70 mg L −1 ) achieved about 90% TC removal within 60 min. It exhibited significantly enhanced reaction kinetics and sustained performance over multiple cycles with minimal iron leaching, indicating strong Fe retention and preserved stability. Radical quenching analysis confirmed a dual oxidative route, involving both radical (·OH and O 2 · − ) and non-radical ( 1 O 2 ) mechanism for TC degradation. The catalyst displayed strong resistance to common inorganic anions and humic substances, highlighting its applicability beyond idealized conditions. CONCLUSION These findings demonstrate that Fe-N/C-A-2P catalyst serves as an efficient heterogeneous Fenton catalyst for removal of TC, providing a feasible approach for mitigating antibiotic contamination in aqueous media. © 2026 Society of Chemical Industry (SCI).

This study develops a conductive material that remains stable in air at extremely high temperatures. Traditional conductive materials, such as carbon- or metal-based systems, often degrade or oxidize near 1000 °C, which limits their use in harsh environments. To solve this problem, we designed a composite material made of heat-resistant aluminum oxide fibers and a gallium–indium liquid metal. A needle-based method was used to distribute the liquid metal evenly through the fiber network, creating continuous conductive pathways. The material was then tested under high temperatures in air to evaluate its electrical stability and mechanical response. The results show that it maintained stable electrical performance at 1000 °C in air for three hours, with very small resistance changes. After repeated heating and cooling between room temperature and 1000 °C, the resistance remained highly stable. High-temperature treatment also reduced the material’s sensitivity to bending and pressure. Structural analysis indicates that a stable oxide layer formed during heating, while the fiber framework preserved the overall structure. These findings provide a simple and effective strategy for designing flexible conductive materials for high-temperature and harsh-environment applications.

The development of two-dimensional (2D) metal composite materials for electromagnetic wave (EMW) absorption is hindered by complex fabrication processes, high raw material costs, and insufficient absorption performance. We ingeniously integrate a multi-metal doping strategy with the oxygen-rich two-dimensional structure of p(C₃O₂)ₓ to successfully construct a defect-rich two-dimensional metal composite microwave absorber. Spectroscopic analysis reveals that multi-metal doping and oxygen release during pyrolysis generate abundant heterogeneous interfaces (oxides/alloys) and induce pronounced electron delocalization, promoting lattice distortions and defect formation. This synergistic effect significantly enhances both local dipole and interfacial polarization, boosting dielectric response. Consequently, the optimized OC-FeMnCuCo sample achieves exceptional EMW absorption with a minimum reflection loss (RL min ) of –55.0 dB and a broad effective absorbing bandwidth (EAB) of 6.8 GHz at an ultra-thin thickness of 1.9 mm. CST simulations further confirm its practical applicability. This work provides a simple, cost-effective strategy for designing advanced 2D absorbers.

Structural polymerization is a primary factor driving intrinsic property changes in calcium silicate (aluminate) hydrate (C–(A)–S–H). However, the mechanisms by which erosive media induce structural polymerization of C–(A)–S–H gel during the service life of cement-based materials remain unclear. This study investigates the effects of both alkaline and acidic sulfates on the composition and microstructural evolution of C–(A)–S–H through various physical and microstructural analyses. The findings indicate that dehydration condensation reactions of Si–OH groups, resulting from decalcification and carbonation processes, are the main contributors to the polymerization silicate tetrahedra. As the aluminum phase increases, the leaching of Al[IV] from the C–(A)–S–H gel after sulfate erosion becomes more pronounced, leading to a tendency for the original silicate–aluminate chain structure to undergo polymerization and reconstruction. Furthermore, aluminum can only promote the polymerization of silicate tetrahedra within a specific range. This study provides a theoretical foundation for regulating concrete microstructure and optimizing its durability.

Platinum-based catalysts are the core components for methanol oxidation reaction (MOR) in direct methanol fuel cells (DMFCs). Although platinum catalysts on nitrogen-doped carbon (NC) show promising MOR activity, the coupled variation between Pt and NC during synthesis obscures their individual contributions. Herein, a solid-phase interface reaction (SIR) successfully decouples their interactions, clarifying the role of each component. We define the ripple effect as the long-range electronic modulation induced by Pt–N coordination, which modulates the electronic state of Pt active sites in a long-range manner and thus significantly accelerates MOR reaction kinetics. Based on this, a metal-free catalytic promoter was developed. When combined with commercial 5 wt% Pt/C, the resulting Pt/C@NC-6hr composite exhibits 1.67 times and twice the mass activity of 5 and 20 wt% Pt/C. Furthermore, statistical results indicate that the mass activity derived solely from the Pt on NC is 4.74 times higher than that of the original 5 wt% Pt/C catalyst, demonstrating a remarkably substantial activity enhancement. After 3600 s chronoamperometry at 0.75 V (vs. RHE), it maintains superior current density. This work elucidates the mechanism of microenvironment-enhanced Pt catalysis via the ripple effect and offers a practical strategy for improving commercial Pt/C. Graphical Solid-phase interface reaction triggers Pt nanoparticle migration, while the resulting Pt-N coordination induces a a long-range electronic modulation effect (ripple effect) that significantly accelerates methanol oxidation reaction kinetics.

A multi-site adsorption ultra-high-temperature retarder (PAINDP) bearing sulfonic, carboxylic, and phosphonic acid groups was successfully synthesized. • PAINDP exhibits excellent overall performance and effectively prolongs cement slurry thickening time at 240 °C. • At ultra-high temperatures, PAINDP remains stably adsorbed on the C3S surface via –PO₃²⁻ and partial –COO⁻ groups. • PAINDP achieves stable multipoint adsorption on the cement surface, effectively coating the cement particles. To address the high-temperature degradation of conventional AMPS-based retarders and the narrow dosage window of small-molecule phosphonates in ultra-deep well cementing, a novel phosphonate-containing polymer retarder (PAINDP) with a multi-site adsorption architecture was designed and synthesized. FTIR and ^1H NMR analyses confirmed the successful synthesis of PAINDP. TGA and in situ FTIR results further demonstrated that the carboxylate and phosphonate adsorption groups remained stable below 260 °C, indicating good thermal stability. Cement-slurry thickening tests showed that, at 240 °C, the addition of 6.9% PAINDP extended the thickening time to 408 min, while maintaining low temperature sensitivity and dosage sensitivity. Mechanistic investigations revealed that the phosphonate groups and part of the carboxylate groups in PAINDP formed stable interactions with Ca sites on the C 3 S surface, thereby maintaining effective interfacial adsorption under high-temperature conditions and providing the cement slurry with sustained and stable retardation performance. This work provides a molecular design strategy and theoretical basis for developing high-temperature polymer retarders suitable for ultra-deep well cementing.

Dual-shelled CoFe@C@PPy fibers are fabricated via microwave hydrothermal and in situ pyrrole polymerization. • PPy loading tunes magnetic-dielectric balance to optimize impedance matching. • Max RCS reduction hits 37.6 dB m² at 35°, RCS <−10 dB·m² for |θ|≥ 4°. • 134.2° contact angle brings excellent hydrophobicity and moisture resistance. The development of microwave absorbing materials (MAMs) with both wide-angle radar stealth capability and moisture resistance has become an urgent requirement for practical deployment. In this work, CoFe@C precursors are rapidly prepared via a microwave-assisted hydrothermal method, followed by in situ polymerization of pyrrole (Py) to construct dual-shelled CoFe@C@PPy hybrid fibers with different PPy loadings. The dual-shell architecture enables systematic regulation of the magnetic-dielectric balance and impedance matching. At an ultrathin thickness of 2.1 mm, the optimal sample achieves a minimum reflection loss (RL) of −52.06 dB at 13.14 GHz and a maximum effective absorption bandwidth (EAB) of 5.92 GHz. More importantly, wide-angle (0–90°) radar cross-section (RCS) simulations reveal outstanding suppression capability, with a maximum RCS reduction of 37.6 dB m 2 at an incident angle of 35°, demonstrating stable performance under oblique illumination in real radar detection scenarios. In addition, the optimal sample exhibits a water contact angle of 134.2°, showing good anti-humidity performance. This work provides a strategy for the design of dual-shelled microwave absorbers with excellent wide-angle radar cross-section reduction through interfacial polarization engineering.

C-type lectins (CTLs) are proteins with carbohydrate-recognition domains. These macromolecules interact with pathogen components, thereby playing important roles in the immune system. Current studies indicate that silkworm CTLs are involved inBombyx morinucleopolyhedrovirus (BmNPV) infection. Nevertheless, the molecular mechanisms through which these CTLs affect viral infection remain unclear. In this study,B. mori C-type lectin 16(BmCTL16) was identified in the silkworm. Its expression was significantly downregulated upon BmNPV infection. Functional assays showed that BmCTL16 overexpression suppressed BmNPV proliferation, whereas its knockdown enhanced BmNPV proliferation. Protein–protein interaction assays confirmed that BmCTL16 interacts with BmNPV protein Bm9 in the cytoplasm. Notably, BmCTL16 promoted the degradation of Bm9 via the ubiquitin–proteasome system. Knockdown of Bm9 by siRNA significantly reduced BmNPV proliferation, confirming that Bm9 is the key target for BmCTL16 to exert its antiviral function. Collectively, this study reveals a novel CTL-mediated antiviral mechanism. BmCTL16 interacts with Bm9 and promotes its ubiquitin–proteasome degradation, thereby inhibiting viral proliferation. Furthermore, BmNPV evades this host defense by downregulating BmCTL16 expression. These findings enhance our understanding of silkworm CTL-mediated antiviral defense and offer novel perspectives on host–virus interactions inB. mori.

A-, B-, and C-type starches exhibited distinct digestibility after conventional cooking. • Cooking disrupted granular barriers and lamellar structures, enhancing enzyme accessibility. • Multi-scale analyses revealed interactions among granular, lamellar, and molecular structural features. • B-type starch formed V-type complexes, partially compensating for the loss of digestion resistance. • C-type starch may retain localized ordered regions, thereby limiting hydrolysis. Starch digestibility is strongly influenced by crystalline polymorphism and processing conditions, yet comparative studies under practical cooking conditions remain limited. This study investigated the multi-scale structural reorganization and in vitro digestibility of A-, B-, and C-type starches after conventional cooking (boiling at 100 °C for 20 min). Cooking disrupted granule surface barriers and lamellar structures, thereby increasing α-amylase accessibility and content of rapidly digestible starch (RDS) for all samples. Among the cooked starches, A-type starch exhibited the highest hydrolysis rate constant ( k = 0.294 min −1 ) and lowest resistant starch (RS) retention (27.83%), whereas C-type starch showed the lowest k value (0.230 min −1 ) and highest RS retention (31.25%), indicating greater resistance to enzymatic digestion. Multi-scale analyses using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and solid-state 13 C cross-polarization/magic-angle-spinning nuclear magnetic resonance spectroscopy ( 13 C CP/MAS NMR) revealed that C-type starch may retain partially ordered B-type-associated regions during cooking, while A-type starch undergoes extensive crystalline lattice disruption. B-type starch formed V-type complexes, which may have partially compensated for the cooking-induced loss of digestion resistance. These transformations provide a structural basis for the divergent digestion kinetics of the three polymorphs. The results demonstrate how crystalline polymorphism and cooking interactively regulate starch digestibility and suggest that C-type starch may serve as a low-glycemic index (low-GI) ingredient, whereas A-type starch may be suitable for starch-based formulations designed for rapid digestibility.

A 100% lignin β -O-4 model conversion with 93.1% monomer selectivity and a high TON was obtained. • The interplay between Ru particle and single atom contributed to the high performance. • Favorable stability under high-temperature heating and high-pressure with reusability > 97%. Catalytic hydrogenolysis is a promising strategy for converting lignin into valuable aryl platform chemicals, contingent upon the availability of high-performance catalysts. The philosophy for the catalyst rational design towards high conversion and selectivity was rarely reported to the best of our knowledge. We illustrate the synergistic interplay between Ru particles and single atoms, contributing to the high catalytic performance. The N-doped carbon-supported Ru catalyst is designed by combining collagen fiber-immobilized tannin adsorption with carbonization (TNC). The Ru is finely dispersed on the TNC support in the form of both single atoms and nanoparticles at a low metal loading of 0.91 wt% (noted as Ru/TNC). It achieved a 100% conversion with a 93.1% aromatic monomer yield in the catalytic hydrogenolysis of lignin β –O–4 model 2-phenoxy-1-phenylethanol (PPE) at 260 °C and 2 MPa H 2 . The primary products of this reaction included ethylbenzene, cyclohexanol, and ethylcyclohexane, and a high turnover number (TON) of 955 was obtained, which surpassed most reports. Specifically, the Ru particle sites facilitate efficient H 2 dissociation, while the single-atom sites provide a weakly adsorbing environment for reaction intermediates due to electron-rich isolated Ru atoms, thereby effectively suppressing over-hydrogenation. This work offers a promising catalyst rational design principle for selective hydrogenation for efficient C–O bond cleavage of lignin, demonstrating significant potential in transforming lignin into value-added platform chemicals.

Exploring new materials with exceptional calcium-magnesium-alumina-silicates (CMAS) corrosion resistance is a pivotal research hotspot in advancing protective coatings for gas turbine engines. In this work, the CMAS corrosion behaviour and degradation mechanism of a newly developed high-entropy (La 0.25 Sm 0.25 Gd 0.25 Ho 0.25 )AlO 3 ceramic were systematically investigated at 1300°C with exposure durations of 4, 25, 50, and 100 h. The unique combination of multiple rare earth and Al compositions in (La 0.25 Sm 0.25 Gd 0.25 Ho 0.25 )AlO 3 ceramic enables simultaneous regulation of both the thermodynamic and kinetic aspects of the corrosion process: a low apatite formation threshold (governed by thermodynamics) and accelerated crystallization of reaction products (governed by kinetics). These factors collectively accelerate the reduction of CMAS corrosion reactivity and the formation of dense protective product layers. Consequently, after 100 h of CMAS exposure, the reaction layer thickness is effectively limited to only 66.4±10.2 μm, smaller than that of single-RE-principle REAlO 3 . This study reveals that (La 0.25 Sm 0.25 Gd 0.25 Ho 0.25 )AlO 3 represents a highly promising candidate for protective coatings applications, while simultaneously highlighting a composition design strategy for developing advanced anti-CMAS materials.
