The volume of discarded thermosetting epoxy composites is increasing. Traditional landfill disposal not only pollutes the environment, but also generates significant resource waste. Promoting their degradation and recycling has emerged as a critical problem for industry sustainability. This work uses ester-based epoxy resins as monomers to rapidly degrade thermosetting ester-epoxy/amine cures in mild circumstances. After concentration and filtration, components such ethylene glycol, sodium carboxylate salts, and nitrogen-containing polyols can be easily extracted from the degradation solution. Specifically, sodium carboxylate salts can be re-synthesized into epoxy resins with identical molecular structures to the original epoxy resin via acidification and epoxidization. Purified regenerated nitrogen-containing polyols combine with diphenyl phosphonyl chloride to form a new flame retardant. When incorporated into standard bisphenol A epoxy/anhydride curing systems at a 25 wt% concentration, this flame retardant elevates the flame retardancy rating from non-rated to V-0 compared to untreated epoxy/anhydride cures, the limiting oxygen index reaches 28.7%, while total smoke release decreases by 12.3%. Concurrently, the mechanical properties of the cured material improved, with tensile strength increasing by 32.8% and elongation at break rising by 50.8%, demonstrating excellent overall performance. Building on previous research that demonstrated the rapid deterioration of ester-based epoxy/amine cured materials and the efficient recovery of sodium carboxylate from degradation solutions, this study enhanced the degradation rate of ester-based epoxy/amine cured materials. Simultaneously, nitrogen-containing polyols found in breakdown products were recovered and reused, resulting in complete recovery and usage of all components from ester-based epoxy/amine cured composites.

The urgent necessity to create affordable adsorbents for the effective elimination of leftover contaminants from wastewater arises from the significant water pollution resulting from the excessive use of dyes. A novel chitosan (CS) /pullulan (PL) hydrogel, chemically cross-linked using polyethylene glycol diglycidyl ether (PEGDE), exhibited high swelling capacity, excellent mechanical stability, and superior adsorption performance. Adsorption tests indicated that CS/PL-2 hydrogel attained a 93.23% removal efficiency for congo red (CR) dye at the concentration of 1000 mg/L. The adsorption capacity of CS/PL-2 hydrogel was investigated in relation to various factors, such as temperature, initial concentration, pH, contact time, and the quantity of adsorbent used. Adsorption kinetics for CS/PL-2 hydrogel were examined utilizing both pseudo-first-order and pseudo-second-order models, with the findings demonstrating that physical adsorption primarily governed the process. The maximum adsorption capacity identified for CS/PL-2 hydrogel, as the Langmuir model, was observed to be 953.60 mg/g, and the thermodynamic analysis of adsorption suggested that the process occurs spontaneously. After five cycles of adsorption, the removal rate of CS/PL-2 hydrogel remained at 70%. In conclusion, this hydrogel adsorbent offers a practical solution for treating CR contaminated wastewater.

Inverted perovskite solar cells have achieved exceptional efficiencies, yet their operational stability, particularly under reverse-bias stress, remains a critical challenge. This instability is fundamentally driven by lattice strain, which lowers ion migration barriers and promotes defect formation. Here, we identify the buried hole-transport-layer/perovskite interface as the principal site of strain accumulation. By incorporating 3-fluorothiophene-2-carboxylic acid (3F-2TC) at this buried HTL/perovskite interface, we directly engineer the initial perovskite crystallization template. This buried interface engineering strategy effectively alleviates intrinsic lattice strain, as unambiguously confirmed by grazing-incidence X-ray diffraction analysis. Crucially, we utilize reverse-bias stress as a diagnostic probe to decouple strain relaxation from mere defect passivation, revealing that a low-strain lattice constitutes the primary defense against bias-induced degradation. Consequently, the champion devices achieve a high power conversion efficiency (PCE) of 26.10% and markedly enhanced stability, retaining 91.58% of their initial PCE after 200 h under − 1.0 V reverse bias. This work thereby establishes the buried interface engineering for strain modulation as a generalizable design principle toward efficient and operationally resilient perovskite photovoltaics.

Converting aqueous ethanol into higher alcohols (HAs) serves as a promising and green pathway for synthesizing valuable chemicals and sustainable fuels from renewable resources. Despite its broad potential, direct carbon chain growth of ethanol toward value-add C 6+ HAs remains a great challenge. In this study, we developed a novel highly hydrophobic NiSn-SDB catalyst utilizing a straightforward physical ball-milling technique. This approach effectively modulates the catalyst's surface hydrophobicity, enhancing the adsorption of alcohol molecules. The optimized NiSn-SDB 1/0.5 catalyst achieved an outstanding catalytic performance with C 6+ HAs selectivity of 70.7% at 86.4% ethanol conversion rate. Notably, the catalyst demonstrated excellent kinetic efficiency, securing 67.1% ethanol conversion and 68.7% C 6+ HAs selectivity within only 1-h reaction. The crucial role of hydrophobic SDB modifier was demonstrated, which enhances the adsorption of HAs molecules, thus promoting the cross coupling process to yield C 6+ HAs. This research presents a highly effective and practical strategy for engineering robust, hydrophobic-modified catalyst for direct aqueous ethanol coupling. Graphical The alternative text for this image may have been generated using AI. Efficiently upgrading aqueous bio-ethanol into C 6+ higher alcohols (sustainable aviation fuel precursors) is highly desirable but severely hindered by mass-transfer resistances and premature intermediate desorption. Herein, we innovatively developed a NiSn-SDB composite catalyst featuring a physical hydrophobic microenvironment. Acting as a microscopic "molecular trap," the SDB polymer grants the catalyst exceptional interfacial tracking capability and robust spatial confinement, successfully overcoming the thermodynamic bottleneck of intermediate desorption. This strategy delivers outstanding performance for C 6+ alcohol synthesis, offering novel insights into breaking the kinetic limitations of continuous carbon chain propagation via surface microenvironment engineering.

Doxycycline (DOX) is a widely used tetracycline antibiotic that frequently persists as a contaminant in food and environmental waters, necessitating reliable methods for routine monitoring. We report an orthogonal dual-mode fluorescence–colorimetric sensing platform based on Mn, Ce-doped carbon dots (Mn, Ce@CDs), a one-pot hydrothermally synthesized nanozyme with bright blue fluorescence and intrinsic oxidase-like activity capable of catalyzing 3,3′,5,5′-tetramethylbenzidine (TMB) oxidation to produce a colorimetric signal. DOX modulates both signal channels via two independent mechanisms: it coordinates with surface metal centers to suppress oxidase-like activity and quenches fluorescence through a combination of inner-filter effect (IFE) and collisional dynamic quenching. The orthogonal responses enable two complementary detection modes. The fluorescence channel offers high sensitivity with a linear range of 0.1–100 µM and a limit of detection (LOD) of 43 nM, while the colorimetric channel provides a linear range of 1–15 µM and a LOD of 0.347 µM. The orthogonal dual-mode design mitigates false signals common to single-mode methods, as the colorimetric channel remains unaffected by interferents that compromise fluorescence detection. Practical applicability is validated by recoveries in spiked wastewater (99.6-103.1%) and milk samples (99.1-100.8%) with relative standard deviations (RSDs) below 3.9%. This work presents a self-validating analytical approach for DOX monitoring in complex matrices, leveraging orthogonal signal outputs to enhance detection reliability.

Transmission line insulators are susceptible to algae contamination in humid environments, resulting in decreased surface hydrophobicity and deterioration of insulation performance, which in turn leads to electrical accidents such as leakage current and flashover
\. To overcome this problem, in this study, stearic acid was used to modify the surface of nano-TiO 2 , and composite coatings with different ratios were prepared. The photocatalytic algae inhibition performance and electrical insulation performance of the coating were evaluated by scanning electron microscopy, contact angle, resistivity, and dielectric loss tests. The results showed that the stearic acid modification significantly improved the dispersibility and hydrophobicity of TiO 2 , among which the sample with a mass ratio of 1:5 (TWC 1 ) had the best performance. After 96 h of algae coverage, the contact angle of TWC 1 decreased by only 30.96%, and the algal cell concentration increased by only about 15%. The surface resistivity decreased by 31.76%, and the dry and wet flashover voltages decreased by 11.13% and 22.68%, respectively, which were better than those of glass and unmodified samples. This composite coating exhibits excellent performance in both photocatalytic algae inhibition and improvement of electrical properties, providing a feasible approach for algae inhibition on transmission line insulators.

Background Status epilepticus (SE) is a life-threatening neurological emergency with high mortality, often leading to acute cerebral edema and chronic cognitive impairment. Its pathology involves both immune and vascular dysfunction. The complement C3/C3a receptor (C3/C3aR) signaling pathway has recently emerged as a key regulator of immune activation and blood-brain barrier (BBB) permeability. This study investigates whether bindarit, a potent anti-inflammatory drug, mitigates SE-induced brain injury through modulation of the C3/C3aR pathway. Methods SE modeling mice were randomized to receive daily bindarit or vehicle. To explore underlying mechanisms, C3aR antagonist (C3aRA) and recombinant C3a were used in additional groups. Post-SE brain injuries were assessed, including survival, memory performance, histopathology, brain edema, BBB integrity, neurovascular inflammation, microglia-astrocyte interactions, and microglial synaptic engulfment. Results We found that bindarit treatment improved survival and memory, reduced histological damage, alleviated brain edema, preserved BBB integrity, and attenuated endothelial inflammation in SE mice. It promoted a shift in microglia from a pro-inflammatory to an anti-inflammatory-associated features, reversed pathological microglia-astrocyte crosstalk, limited synaptic elimination, and restored microglial morphology. Mechanistically, bindarit inhibited neurotoxic astrocyte-derived C3 production and reduced C3aR expression in both microglia and endothelial cells. C3aRA produced comparable protective effects, whereas co-administration of C3a partially negated bindarit’s benefits. Conclusions Bindarit confers robust neuroprotection in SE by preserving BBB integrity, attenuating neurovascular inflammation, reducing synaptic loss, and improving cognitive outcomes. These effects are mediated predominantly through inhibition of the C3/C3aR pathway, highlighting bindarit as a promising therapeutic candidate for SE.

Ulcerative colitis (UC) is characterized by intertwined defects in the epithelial barrier, microbiota composition, and immune signaling, which collectively sustain inflammation and drive fibrosis. Here, we report a multifunctional oral nanoplatform OMV-LbL@Upa (OUL), comprising probiotic-derived outer membrane vesicles (OMVs) encapsulating the JAK–STAT inhibitor upadacitinib (Upa), further functionalized with a trans-cinnamic acid/chitosan-based layer-by-layer (LbL) coating. The LbL architecture significantly enhanced gastric stability and intestinal retention, enabling colon-targeted release while preserving OMV bioactivity. In both acute and chronic UC models, OUL significantly improved disease activity, restored tight junction proteins, corrected intestinal permeability, rebalanced gut microbiota, and reprogrammed macrophage polarization. Mechanistically, OUL suppressed JAK–STAT signaling pathways, culminating in attenuated collagen deposition and the downregulation of pro-fibrotic markers (α-SMA and vimentin). With no overt systemic toxicity observed, this orally administered nanoplatform integrates microbiota/epithelial restoration with targeted JAK1 inhibition to achieve anti-inflammatory and anti-fibrotic benefits, offering a clinically promising strategy for the management of UC.

Photothermal therapy (PTT) is recognized for its precise manipulability and exceptional spatiotemporal control but faces challenges such as thermotolerance, weak penetration, and collateral tissue damage. Herein, we presented a strategy that enabled tumor-targeted PTT, reduced interstitial fluid pressure (IFP), promoted deep tumor penetration, enhanced radiosensitization, and counteracted thermoresistance. An engineered bacteria-based delivery system (R.S@BiOI) responsive to low-dose X-ray was constructed via electrostatic adsorption of bismuth oxyiodide quantum dots (BiOI QDs) onto the natural photothermal agent Rhodobacter sphaeroides (R.S). Leveraging the hypoxic targeting capability of R.S, R.S@BiOI facilitated tumor-specific enrichment and penetration. Meanwhile, X-ray-triggered radiolysis of water by surface-bound BiOI QDs generated hydroxyl radicals, which reduced tumor IFP, enhanced the deep and uniform distribution of the R.S@BiOI composite, and minimized collateral thermal damage to surrounding healthy tissues. Furthermore, X-ray irradiation downregulated the expression of heat shock proteins, attenuating cellular thermotolerance and synergistically improving the efficacy of PTT. Meanwhile, R.S@BiOI elicited a robust anti-tumor immune response, which acted in synergy with radiotherapy and PTT to potentiate the overall antitumor efficacy. The bacteria-based delivery system enhanced intratumoral accumulation and improved tumor distribution, resulting in markedly superior tumor growth suppression, prolonged survival in animal models, and a well-tolerated safety profile with no significant systemic toxicity observed in critical organs. Thus, this study presents a strategy for fabricating X-ray-responsive engineered bacteria that potentiate the therapeutic efficacy of PTT in the treatment of prostate cancer. Graphical abstract

Lightweight broadband microwave absorbers with strong attenuation remain challenging because efficient absorption requires balanced impedance matching and electromagnetic loss over a wide frequency range. Herein, hierarchical core–shell BCN@CoNi@PANI (BCNPa) composites were rationally designed by integrating BCN, CoNi alloy, and conductive PANI. BCN serves as a lightweight dielectric substrate, CoNi provides magnetic loss, and the outer PANI shell regulates dielectric response and conductive loss. The electromagnetic properties of BCNPa can be effectively tuned by adjusting the PANI content. The excellent absorption performance over 2–18 GHz originates from the synergistic effects of impedance matching, dielectric loss, magnetic loss, and hierarchical structural attenuation. Dielectric loss is mainly related to defect-induced dipole polarization, interface-related polarization relaxation, and conductive loss from the π-conjugated PANI shell, while magnetic loss arises from natural resonance, exchange resonance, and eddy current loss of CoNi. Benefiting from optimized dielectric–magnetic balance, BCNPa-2 achieves ultralow minimum reflection loss ( RL min ) of − 81.4 dB at 14.12 GHz and an ultrabroad effective absorption bandwidth ( EAB ) covering nearly the entire measured range. This work provides an effective strategy for high-performance broadband microwave absorbers.

The escalating freshwater scarcity necessitates the development of highly efficient solar-driven interfacial evaporators. However, existing fabric-based evaporators still face challenges in long-term durability and salt management. Herein, we report a novel and durable candle soot-deposited basalt/cotton bilayer fabric evaporator (CBFE), constructed via tailored fiber placement (TFP) technology, followed by candle soot deposition and polydopamine (PDA) adhesion treatment. The CBFE features a unique core-sheath yarn design, where a hydrophilic cotton core ensures efficient water transport, and a basalt fiber sheath provides mechanical strength and a photothermal conversion substrate. TFP enables precise control over the fabric architecture, optimizing water supply and vapor escape. Carbon nanoparticles are introduced through candle soot deposition, with PDA enhancing their adhesion to the basalt fiber surface. Under 1 sun illumination, the CBFE achieves an evaporation rate of 1.5 kg·m −2 ·h −1 in 3.5 wt.% NaCl solution, demonstrating excellent cyclic stability and salt-resistant performance (maintaining 1.19 kg·m −2 ·h −1 in 20 wt.% NaCl solution). Outdoor tests and wastewater purification experiments (for methyl violet and rhodamine B) further confirm its high efficiency and versatility in practical applications. This work provides a new strategy for developing high-performance, long-lifespan solar evaporators, holding significant promise for sustainable freshwater production and environmental remediation.
