The photoreactions on suspended particulate matter (SPM) surface were a non-negligible environmental transformation process for hydrophobic organic pollutants in river water environments. Herein, SPM samples from four representative basins in China—the Yangtze River, Yellow River, Pearl River, and Haihe River—were chosen and focused on the effects of differences in the SPM composition on the phototransformation behavior of 2,4′-dichlorodiphenyl trichloroethane (o,p′-DDT). The experimental results demonstrated a lower light-screening effect, lower organic carbon content, and higher proportions of carbonate minerals and quartz components conducive to the photodegradation of o,p′-DDT on the SPM surface. The compositional characteristics of endogenous dissolved organic matter (DOM) also influenced the generation of reactive oxygen species (ROS) by SPM. Mass spectrometry analysis revealed that although the SPM from different basins did not alter the types of o,p′-DDT products, it influenced their yields. The estrogenic effects of the products were preliminarily assessed through molecular docking with the human estrogen receptor, and the phototransformation process on the surface of Haihe River SPM might have a more substantial estrogenic effect. These findings deepened the understanding of the regional differences in pollutant fate and might provide reference information for the management and regulation of pollutants in different regions.

Herein, covalent organic framework (COF) and covalent triazine framework (CTF) have been successfully combined for electrochemical sensing via carboxylated multi-walled carbon nanotubes (COOH-MWCNTs). The COF was synthesized from 1,3,5-tris-(4-formylphenyl) benzene (TFPB) and benzidine (BD), named TFPB-BD-COF. Meanwhile, CTF was synthesized by 1, 4-dicyanobenzene (DCB), then chemically activated with KOH at 700 °C to obtained chemically activated porous product, caCTF-1–700. A novel electrochemical sensor based on TFPB-BD-COF/caCTF-1–700/COOH-MWCNT composite was constructed for simultaneous detection of acetaminophen (ACOP) and 4-aminophenol (4-AP). The electrochemical behaviors of the ACOP and 4-AP on the TFPB-BD-COF/caCTF-1–700/COOH-MWCNT electrode were explored via differential pulse voltammetry (DPV) and cyclic voltammetry (CV). The fabricated TFPB-BD-COF/caCTF-1–700/COOH-MWCNT composite modified glassy carbon electrode (GCE) possessed outstanding electrocatalytic performance for the electro-oxidation of acetaminophen (ACOP) and 4- aminophenol (4-AP). Under optimal conditions, the linear ranges were 0.6–150 μM for ACOP and 4-AP, respectively, with the low detection limits of 0.053 μM and 0.075 μM, respectively. In addition, it also showed excellent selectivity, repeatability, reproducibility and stability. The proposed modified electrode was applied for the determination of ACOP and 4-AP in acetaminophen tablet and Yellow river water and obtained satisfactory recovery between 96.31~103.96% and 97.2~101.6%, respectively.

In this study, a porous carbon support (CuCN) with a high specific surface area and an N-doped Cu-N-C network was synthesized by pyrolyzing copper acetylacetonate on a metal-organic framework (ZIF-8) at 900 °C. To investigate the relationship between the preparation process and performance of CuCN-supported palladium nanoparticles, a light-induced synthesis method was employed to replace the traditional high-temperature thermal reduction process, enabling the controlled loading of palladium nanoparticles onto CuCN. A Cu- and N-co-doped carbon-supported palladium nanocatalyst (Pd/CuCN-M) was prepared, and the effects of optimal illumination conditions and reducer types on the catalyst were explored. The results show that the Cu- and N-co-doped carbon-supported palladium nanocatalyst, designated Pd/CuCN-M1, prepared using methanol as the reducing agent and irradiated with near-ultraviolet light at 395 nm, exhibits high catalytic activity and stability. The rate constant for the reduction of p-nitrophenol (4-NP) reached 2.1 min⁻¹, and the conversion rate remained at 90.2% after five cycles of stability testing. This study presents a green, convenient, and highly efficient method for synthesizing Pd nanocatalysts, offering a new approach to reducing the use of precious metals and treating p-nitrophenol-based pollutants generated in industrial production.

The rapid evolution of high-power flexible electronics necessitates materials that concurrently enable efficient heat dissipation and high-precision thermal monitoring. Conventional ionogels suffer from intrinsically low thermal conductivity, which induces severe thermal hysteresis, fundamentally compromising their accuracy in dynamic thermal detection. Herein, rather than treating copolymer regulation or h-BN filling as isolated design elements, we propose a thermally coupled ionogel design aimed at reconciling two usually conflicting requirements: rapid heat equilibration and high thermoresistive sensitivity. P(DMAA-co-AAM)/h-BN composite ionogels are fabricated via in-situ UV-initiated free-radical polymerization, in which N,N-dimethylacrylamide (DMAA) and acrylamide (AAM) form a mechanically compliant and ion-transportable copolymer network, lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) provides thermally activated ionic pathways, and hexagonal boron nitride (h-BN) nanosheets introduce filler-assisted thermal transport pathways. Systematic optimization reveals that a DMAA-to-AAM mass ratio of 3:1 with 20 wt% h-BN yields the optimal synergy among mechanical flexibility, thermal transport, and ionic conduction. The resulting composite achieves a thermal conductivity of 0.469 W/(m·K), representing a ∼160% enhancement over the pristine matrix, which effectively suppresses heat accumulation. Concurrently, the ionogel exhibits an ultra-high temperature coefficient of resistance (TCR) of −13.5%/°C and a thermosensitive coefficient (B value) of 3879 K within 0-20°C. Benefiting from the enhanced thermal transport performance, the dynamic thermal response speed of this series of ionogel sensors (30°C → 35°C) is significantly accelerated with the increase of h-BN loading: the T90 response time of the 10 wt%, 20 wt%, and 30 wt% h-BN samples is 32.40 s, 24.34 s, and 15.14 s respectively. Meanwhile, the devices can still maintain stable and reversible resistance switching characteristics over 50 heating-cooling cycles. This study achieves the synergistic enhancement of the thermal management and temperature sensing performance of the ionogel, providing an ideal material platform for the next-generation wearable electronic devices and intelligent thermal management systems.

p -Aminophenol (PAP) is an important intermediate in the synthesis and environmental degradation of acetaminophen, and it is widely found in pharmaceutical and dyeing wastewater. However, systematic studies on its toxicity to freshwater invertebrates remain limited. In this study, Biomphalaria glabrata was used as a model organism to comprehensively evaluate the acute and chronic toxicity of PAP across three developmental stages (embryo, juvenile, and adult stages) and to identify key target organs of damage through histopathological analysis. Acute toxicity tests revealed a clear stage-dependent sensitivity gradient, with embryos being the most sensitive (216 h LC 50 = 4.16 mg/L, 95% CI = 3.94 to 4.39 mg/L), followed by juveniles (96 h LC 50 = 10.87 mg/L, 95% CI = 9.38 to 12.36 mg/L) and adults (96 h LC 50 = 26.41 mg/L, 95% CI = 22.78 to 29.58 mg/L). During a 21-day chronic exposure, PAP at concentrations of 9-13 mg/L significantly inhibited adult growth and reproduction, with egg-laying nearly completely suppressed at concentrations ≥11 mg/L. Histopathological observations revealed hepatopancreatic acinar dilation, vacuolation, and necrosis, as well as gonadal follicle atrophy and germ cell degeneration, indicating direct damage to the metabolic and reproductive systems. This study integrates multiple lines of evidence linking “developmental sensitivity, functional impairment, and organ pathology,” suggesting that PAP may pose potential risks to mollusk populations under high or pulse exposure scenarios.

Titanium dioxide (TiO 2 ) has been extensively utilized owing to its outstanding physicochemical properties in the field of photocatalytic degradation. However, its efficiency is fundamentally limited by poor charge carrier mobility and severe recombination. These defects critically impair both charge utilization and reactive oxygen species generation. Herein, we in-situ hydrothermally grow ferroelectric barium titanate (BTO) layers on vertically aligned TiO 2 nanorod arrays (NRs), polarize the sample via an external electric field, and load graphene quantum dots (GQDs) through controlled impregnation, successfully constructing a TiO 2 /BTO-Polarized/GQDs (TiO 2 /BTO-P/GQDs) heterostructure. An external electric field induces a stable depolarization field in the BTO layer, creating a persistent interfacial driving force that enhances charge extraction from TiO 2 while suppressing bulk and surface electron-hole recombination. The BTO layer further acts as an electron transfer highway, efficiently channeling photogenerated electrons to GQDs. The π-conjugated system of GQDs serves as both an electron accumulation platform and a chemically active surface, facilitating pollutant adsorption and activation, thereby synergistically accelerating degradation kinetics through combined electron storage and catalytic effects. TiO 2 /BTO-P/GQDs demonstrated a 2.06-fold higher (OTC) degradation efficiency (82.5%) compared to unmodified TiO 2 (40%) within 90 min. This study provides novel insights into ferroelectric polarization-enhanced photocatalytic degradation efficiency. Implication This work presents a highly efficient, stable, and recoverable photocatalyst (TiO 2 /BTO-P/GQDs) for degrading persistent antibiotic pollutants like oxytetracycline in water. By enabling effective solar-driven remediation of agricultural wastewater, it offers a promising strategy to mitigate antibiotic contamination, protect aquatic ecosystems, and reduce risks to microbial communities and human health associated with residual antibiotics in the environment.

A novel citric acid-assisted in situ reduction method has been developed for the synthesis of bimetallic AuPd alloy nanoparticles supported on amine–phosphate-functionalized carbon nanotubes (AuPd/NH2-P-CNTs). In this strategy, formic acid acts not only as the reducing agent for reducing metal precursors, but also as the hydrogen source for the subsequent catalytic dehydrogenation. The introduction of citric acid significantly accelerates the reduction kinetics and promotes the uniform formation of ultrafine AuPd nanoparticles (∼1.8 nm). As a result, the optimized Au0.5Pd0.5/NH2-P-CNTs exhibit an extraordinary catalytic activity and 100% H2selectivity during hydrogen generation from FA with sodium formate as an additive, affording a remarkable initial turnover frequency of 5663.94 mol H2mol Pd−1h−1at 303 K. The experimental results reveal that the -NH2and -P functional groups on the support are crucial for stabilizing and uniformly dispersing the alloy nanoparticles. Furthermore, the enhanced reaction rate can be attributed to the strong metal–support interaction established between AuPd nanoparticles and -NH2-P-CNT supports. This work provides a new perspective on the design of highly efficient Pd-based catalysts for hydrogen production from formic acid.

Developing flame-retardant epoxy resin (EP) with high performance has drawn extensive attention recently due to the growing public concern for fire safety. However, the simultaneous enhancement of flame retardancy and toughness without the sacrifice of mechanical strength and thermal stability is still a challenge for EP. Herein, a novel kind of imidazole-based reactive flame retardant MD containing P/N/Si was synthesized and applied into EP. The results demonstrated that due to the presence of P/N/Si multiple flame-retardant elements, incorporating 4 wt% MD could make EP/MD pass UL-94 V-0 grade and have a limiting oxygen index (LOI) of 29.7%. Meanwhile, compared with pure EP, the peak heat release rate (PHRR), total heat release rate (THR), peak smoke production rate (PSPR), and total smoke production (TSP) of EP composite containing 4 wt% MD exhibited an obvious reduction of 41.5%, 11.4%, 24.2%, and 12.9%, respectively. Moreover, thanks to the high reactivity of imidazole groups, the MD could participate in the cross-linking reactions of EP and form strong interfacial interaction between the matrix and flame retardant. Therefore, the mechanical strength and toughness as well as the glass transition temperature of EP/MD composites could be simultaneously and greatly enhanced (tensile strength +30%, flexural strength +35%, impact strength +22%, and T g + 7°C). This work provided a feasible methodology for the fabrication of highly efficient flame-retardant EP with prominent mechanical and thermal properties. Highlights A reactive flame-retardant MD containing DOPO groups, imidazole moieties, and siloxane segments was synthesized in mild conditions. MD endowed EP with satisfying flame-retardant and smoke suppression properties. EP/MD composites realized simultaneous improvement of fire safety, mechanical strength, and glass-transition temperature in a small amount of MD.

Background Acute kidney injury (AKI) remains a major clinical challenge lacking effective pharmacological interventions. Ferroptosis has emerged as a critical mechanism contributing to renal tubular injury. While p -coumaric acid (pCA), a natural phenolic compound, has been reported to exert renoprotective effects, its regulatory role in ferroptosis, particularly under different pathological contexts of AKI, remains incompletely understood. Methods A folic acid (FA, 250 mg/kg)–induced AKI model was established in mice treated with pCA (10 and 50 mg/kg). Renal function, histopathology, inflammatory responses, and ferroptosis-related markers were evaluated. Integrated transcriptomic and metabolomic analyses were performed to identify global regulatory alterations. Mechanistic studies were conducted in erastin-treated HK-2 cells. NRF2 signaling involvement was further assessed using pharmacological inhibition. Results pCA treatment significantly improved renal function, attenuated tubular injury, and suppressed inflammatory responses in FA-induced AKI. Multi-omics integration revealed that pCA markedly reprogrammed metabolic and transcriptional networks associated with ferroptosis and redox homeostasis. Mechanistically, pCA restored antioxidant capacity and normalized the expression of ferroptosis-related proteins. Notably, pCA activated NRF2 signaling, leading to upregulation of downstream targets involved in ferroptosis regulation. Inhibition of NRF2 partially abolished the cytoprotective and anti-ferroptotic effects of pCA in vitro. Conclusion pCA alleviates FA-induced AKI by suppressing ferroptosis through NRF2-dependent regulation of redox and metabolic homeostasis, highlighting NRF2 as a potential therapeutic target for AKI.

Selective separation of 90 Sr 2+ and 137 Cs + from nuclear wastewater is a significant challenge in the field of environmental remediation. In this paper, magnetic P-type zeolite composites loaded with Fe 3 O 4 were successfully synthesized via an alkali fusion-assisted hydrothermal method using lithium porcelain clay tailings (LPCT) as the silicon-aluminum source, achieving resource utilization of solid waste. The material exhibited excellent selective adsorption capacity for Sr 2+ : under the conditions of pH = 6 and a dosage of 2 g/L, the removal rate for Sr 2+ (100 mg/L) reached 99.4%, while that for Cs + (50 mg/L) was only 55.2%. In simulated/real seawater systems, the material maintained exceptionally high selectivity for trace Sr 2+ (with a K d value of 1.265 L·g –1 in simulated seawater). Mechanistic studies revealed that Sr 2+ undergoes specific ion exchange primarily by substituting Na + within the zeolite framework (adsorption energy: −2.37 eV), forming stable chemical bonds; in contrast, Cs + binds only through weak physical adsorption (adsorption energy: −0.85 eV), making it susceptible to displacement by competing ions. After five cycles, the Sr 2+ removal rate remained above 65%. This study presents a strategy for upcycling solid waste into high-performance functional materials and offers a promising solution for the efficient and selective separation of radioactive Sr 2+ from complex aqueous environments, highlighting its potential for practical nuclear wastewater treatment.

The practical implementation of lithium‑sulfur (Li - S) batteries is critically hindered by the polysulfide shuttle effect and the sluggish conversion kinetics of lithium polysulfides (LiPSs). Herein, we design a freestanding interlayer comprising bimetallic phosphide nanoparticles embedded within interconnected porous carbon nanofibers (NiCoP@PCNF). In this architecture, the conductive PCNF skeleton functions as a physical barrier and facilitates rapid electron/ion transport, while the polar NiCoP nanoparticles serve as robust chemical anchors for LiPSs. Notably, density functional theory calculations and electrochemical analyses reveal that NiCoP acts as an efficient electrocatalyst by modulating its d-p band center, which optimizes electron transfer and substantially accelerates the liquid-solid conversion of LiPSs. Benefiting from this synergistic adsorption-catalysis effect, Li-S cells equipped with the NiCoP@PCNF interlayer deliver outstanding electrochemical performance, including a high initial capacity of 1652 mAh g −1 at 0.1C, an excellent rate capability of 1013 mAh g −1 at 2C, and exceptional cycling stability with a retained capacity of 757 mAh g −1 after 200 cycles at 3.0C. This work highlights a strategic design for multifunctional interlayers through the integration of conductive carbon frameworks with bimetallic phosphides, offering a promising pathway toward high-performance Li-S batteries.

Polymer dielectrics are promising materials for electrostatic capacitors because of their high dielectric strength and fast charge-discharge capability. However, improving the energy-storage density of fluorinated ferroelectric polymers remains challenging because enhanced polarization is often accompanied by reduced breakdown strength. In this work, all-organic poly(vinylidene fluoride- trifluoroethylene-chlorofluoroethylene)/poly(methyl methacrylate) [P(VDF-TrFE-CFE)/PMMA] dielectric films are prepared by solution blending and casting. By tuning the blend ratio, the intermolecular interactions and crystallization behavior of the films are systematically regulated, resulting in distinct changes in their electrical properties. The results suggest that dipolar interactions between PMMA carbonyl groups and polar groups in P(VDF-TrFE-CFE) disturb chain packing and suppress crystallization, thereby reducing dielectric loss and improving breakdown stability. At the optimized composition, the P(VDF-TrFE-CFE)/PMMA (50/50 wt.%) film delivers a dischaged energy density of 17.12 J/cm3 with an energy-storage efficiency of 88.11%. Further γ-irradiation of the optimized film at doses of 10-150 kGy leads to additional improvement in dielectric energy-storage performance. These results demonstrate that regulating intermolecular interactions and crystalline morphology through all-organic blending and irradiation is an effective strategy for developing high-performance polymer dielectrics.
