NiFe PBA exhibits laccase-mimic for ORR and electrocatalyze oxidation of CC and HQ. • A self-powered sensor by assembling NiFe PBA as both anode and cathode catalyst. • The sensor capable of detecting CC or HQ in simulated wastewater satisfactorily. Biofuel cells are widely applied in designing self-powered sensors (SPS) due to their rich fuel source, environmental friendliness, and advantages in operating under neutral pH and room temperatures. However, they are limited by inherent drawbacks of biological enzymes as catalysts, such as poor stability and high costs, greatly restricting their real applications. Herein we report on NiFe Prussian blue analogue (PBA) nanocubes with good mimicking laccase activity, which can not only exhibit excellent oxygen reduction reaction in the absence of electron mediators, but also efficiently electrocatalyze the oxidation of phenolic fuels. Subsequently, a dual-chamber enzyme-free fuel cell was constructed using NiFe PBA as both the anode and cathode catalysts as well as catechol (CC)/hydroquinone (HQ) as the fuel. Based on this, a SPS was developed to detect CC or HQ. The maximum power density ( P max ) of the HQ-fueled sensor is linear within 0.5 μM–5 mM HQ in three parts. Similarly, the P max for CC-fueled sensor is linear with 5 μM–5 mM CC in three parts. Moreover, the sensor has excellent selectivity and is capable of monitoring simulated wastewater. Thus, this work demonstrates an efficient enzyme-free biofuel cells based SPS using the same nanomaterial as anode and cathode catalyst.

PAO-Fe: Efficient and durable heterogeneous Fenton catalyst made from PAN fibers • It achieves high specific rate constants at a low H 2 O 2 -to-BPA molar ratio (11.4:1) • Effective across pH 1–7 and in real water matrices, widely applicable, recyclable • Amidoxime groups enable iron chelation and H 2 O 2 activation • Degradation intermediates have lower toxicity than BPA The development of efficient and durable heterogeneous catalysts remains a key challenge for the remediation of persistent organic pollutants via catalytic wet peroxide oxidation. In this study, polyacrylonitrile (PAN) fibers were employed as catalyst supports to meet this challenge, leveraging their robustness, versatile functionalization, and ease of separation. Amidoxime-chelated iron (AO-Fe) active sites were assembled on PAN fibers through optimized amidoximation and iron-loading conditions. The resulting catalyst (PAO-Fe) exhibits exceptionally high normalized rate constants (82.29 L/(min·mol Fe) and 0.438 L/(h·m 2 )), enabling 97.3% bisphenol A (BPA) removal within 2 h with a low H 2 O 2 dosage (H 2 O 2 -to-BPA molar ratio of 11.4:1) under mild conditions (pH 6, 30 °C). PAO-Fe operates effectively across pH 1–7, efficiently degrades various dyes and pharmaceuticals, and maintains robust activity in real water matrices. Reusability tests demonstrate good performance over five cycles with low iron leaching (<0.62 mg/L), and the spent catalyst can be readily regenerated by iron reloading. Catalytic efficiency is modulated by coexisting anions and natural organic matter in a species- and concentration-dependent manner. Mechanistic studies reveal that amidoxime groups are essential for iron chelation and facilitate H 2 O 2 activation by forming a ternary complex with BPA, generating hydroxyl radicals as the major reactive species. The degradation intermediates of BPA are assessed to have lower toxicity. This work demonstrates that fiber supports integrated with AO-Fe active sites offer a viable strategy for developing high-performance heterogeneous Fenton-like catalysts.

Aged nanoplastics shift BPA toxicity from membrane damage to mitochondrial failure. • Surface oxidation rises 12.8-fold after aging, driving 8.9-fold zeta shift. • Toxicity hierarchy inverts over time: combined exposures dominate at Day 21. • Aged nanoplastics threaten the endangered horseshoe crab more than pristine NPs. Despite mounting evidence that environmental weathering alters the surface chemistry of nanoplastics (NPs), most ecotoxicological studies continue to use pristine particles, leaving the toxicological consequences of NP aging insufficiently resolved. Here, we systematically compared the toxicity of pristine and aged polystyrene NPs (PS-NPs), in combination with bisphenol A (BPA), on juvenile Chinese horseshoe crabs ( Tachypleus tridentatus ), an endangered IUCN Red List marine sentinel. Six treatments—control, BPA, pristine NPs, aged NPs, pristine NPs + BPA, and aged NPs + BPA—were administered over 21 days, with sampling at days 7 and 21. Biomarkers spanning surface chemistry, mitochondrial function, membrane integrity, respiratory chain activity, and oxidative stress were integrated using IBRv2, PCA, and Pearson correlation. UV aging markedly altered NP surfaces: zeta potential shifted from −5.6 mV to −49.9 mV, and the carbonyl index increased 12.8-fold. IBRv2 scores at day 7 ranked: aged NPs (96.7) > aged NPs + BPA (53.6) > pristine NPs + BPA (44.5) > pristine NPs (37.3) > BPA (21.2); at day 21, the ranking reorganized to aged NPs + BPA (88.7) > pristine NPs (57.3) > aged NPs (49.0) > pristine NPs + BPA (46.5) > BPA (45.0). Critically, aged NPs + BPA caused toxicity dominated by mitochondrial respiratory chain impairment (SDH declining to 22% of control; MDA reaching 206 nmol·mL −1 at day 21), whereas pristine NPs + BPA drove acute membrane lipid peroxidation—a divergence confirmed by PCA. Our findings demonstrate that NP aging shifts the mode, rather than merely the intensity, of combined toxicity with BPA, with implications for environmental risk assessment.

Herein,
thioether cyclodextrin-incorporated triazine-based porous
organic polymer (S-CD-TPOP) featuring multifunctional nature was prepared
for iodine vapor uptake and adsorption of organic micropollutants
(OMPs) and Hg 2+ from water. Polycondensation between specially
designed per-6-(4-formylbenzylthio)-β-cyclodextrin (FB-S-CD)
and 1,4-bis(2,4-diamino-1,3,5-triazine)benzene (BDTAB) affords the
S-CD-TPOP containing CD cavities, thioether, and triazine units as
well as high nitrogen content. S-CD-TPOP exhibits a high surface area
of 467.42 m 2 /g with 28.56% nitrogen and 2.16% sulfur contents.
S-CD-TPOP shows iodine vapor uptake of 1.70 g/g, where charge transfer
plays a dominant role. Moreover, S-CD-TPOP displays quick adsorption
kinetics and excellent removal efficiencies for phenols with a maximum
adsorption capacity ( q m ) of 181.16 mg/g
for bisphenol A (BPA). Host–guest and hydrophobic interactions
serve as the main mechanisms for the adsorption of OMPs onto S-CD-TPOP.
Additionally, S-CD-TPOP demonstrates rapid Hg 2+ adsorption
kinetics with a q m value of 45.25 mg/g,
primarily driven by coordination between the −S– group
and Hg 2+ . Furthermore, S-CD-TPOP exhibits great application
potential for simultaneously removing low concentrations BPA and Hg 2+ from river water. S-CD-TPOP also exhibits excellent reusability
and is a promising and versatile adsorbent for removing diverse environmental
pollutants.

Bisphenol A (BPA) pollution severely threatens aquatic ecology and human health, and peroxymonosulfate (PMS)-based advanced oxidation processes are efficient for refractory organic pollutant remediation. Our previous study realized the in-situ synthesis of nitrogen-doped swine manure biochar (NBC) for enhanced PMS catalysis, yet abundant endogenous silicon in swine manure remains inert as SiO 2 and fails to contribute to catalysis, restricting the full resource utilization of livestock waste. Targeting this bottleneck, we herein develop a facile ball-milling coupled with HF etching strategy to activate intrinsic silicon on NBC without exogenous dopants. This approach converts inert SiO 2 into reactive Si–O–C interfacial sites while preserving the original nitrogen-doped carbon framework, yielding a Si modified biochar (Si-NBC). Benefiting from the synergistic effect of Si–O–C bridges and inherent nitrogen active sites, the optimized Si-NBC achieves 98% BPA removal within 20 min and 42% total organic carbon mineralization, with a rate constant 18-fold higher than pristine NBC. It performs robustly across pH 3–9, tolerates common coexisting anions, and maintains removal above 90% for 72 h in a continuous-flow reactor. Mechanistic investigations reveal a synergistic non-radical regime: singlet oxygen, generated at C–C and graphitic N sites, dominates the oxidative process, while an electron-transfer pathway, mediated by graphitic N and Si–O–C bridges, accelerates interfacial charge shuttling. Degradation intermediates exhibit markedly reduced ecotoxicity compared to parent BPA. By leveraging in-situ interfacial engineering of biomass-derived carbons, this work both valorizes the underutilized silicon in livestock waste and establishes a mechanistic rationale for the design of high-performance, eco-friendly PMS catalysts.

Epoxy resin is confronted with the trade-off among high
heat resistance,
high modulus, and good toughness. In order to address the challenge,
a series of poly(ether sulfone)-polyetheretherketone multi-block copolymers
(PE b PK) are synthesized with hydroxyl-terminated
poly(ether sulfone) and fluorine-terminated polyetheretherketone oligomers
with different molecular weights as build-blocks. As a proof-of-concept,
the PE b PKs are applied as modifiers to toughen bisphenol
A epoxy (E51) with 4,4 ′ -diaminodiphenyl sulfones as a hardener.
Introducing rigid PEEK segments into flexible PES improves the thermal
resistance and modulus of the epoxy composites and without at expanse
of toughness. It is due to the inherent rigidity of the PEEK segments
and the molecular-level microphase separation of the composites. Apart
from PE b PK-5 k /10k (PE b PK-xk/yk indicates that in a multiblock copolymer, the M n of PES is x and the M n of
PEEK is y, with units in thousand Daltons), other variants gain prominently
enhanced modulus and toughness. This PE b PK modification
offers a strategy for developing high-performance epoxy composites.

The development of the high catalytic performance zinc-based catalyst featuring eco-friendly remains a considerable challenge in environmental treatment. Serving as a nitrogen-rich anchoring ligand, 3,5-diamino-1,2,4-triazole was adopted to construct a porous Zn-based catalyst through a facile grinding-assisted pyrolysis route. Zinc species served as both a pore-forming agent and active site, endowing the ZnNC with a zinc loading of 11.26 wt% with a specific surface area of 388.29 m 2 /g. The as-prepared ZnNC displayed outstanding performance in activating peroxymonosulfate (PMS), enabling complete degradation of the refractory contaminant carbamazepine (CBZ) within 15 min, and the apparent rate constant (k obs ) was 0.395 min⁻¹, surpassing the performance of most reported metal-based catalysts. Interestingly, the reaction at 0 °C was more favorable for the degradation of CBZ, which was attributed to the strengthened adsorption of CBZ on the ZnNC at low temperatures, differing from most previous reports that the degradation rate increased with rising temperature. Quenching experiments in combination with EPR characterizations revealed that 1 O 2 acted as the predominant reactive oxygen species (ROS) in the ZnNC/PMS system, endowing the catalytic system with wide pH adaptability and strong anti-interference capability against coexisting ions. Importantly, ZnNC maintained a relatively stable CBZ removal rate after five cycles and during 24 h of continuous operation, demonstrating its preliminary application potential. This work provides a viable and facile strategy for the rational construction of highly active and stable zinc-based catalysts for wastewater remediation.

Bisphenols (BPs) are widespread environmental endocrine disruptors, but their potential depression-related neurotoxicity has not been systematically assessed. Here, we combined machine learning (ML), network toxicology, molecular docking, and in vivo experiments to screen 26 bisphenols for depression-related neurotoxic risk. We first integrated bisphenol A (BPA)-related targets with depression-related genes to build a chemical-gene-phenotype-disease network and an adverse outcome pathway (AOP) framework. We then used nine ML algorithms to rank the predicted risk of the 26 bisphenols. Molecular docking showed that the predicted high-risk compounds had strong binding affinity for estrogen receptor 1 (ESR1). The AOP analysis further suggested the involvement of the ESR1–cAMP response element-binding protein 1 (CREB1)–glutamate ionotropic receptor N-methyl-D-aspartate type subunit 2B (GRIN2B) pathway. In vivo experiments showed that BPA exposure caused neuronal damage in the cornu ammonis 3 (CA3) region of the rat hippocampus and significantly reduced the messenger RNA (mRNA) expression of the corresponding genesEsr1,Creb1, andGrin2bin hippocampal tissue. Overall, this study screened and prioritized the model-predicted depression-related neurotoxic risk of 26 bisphenols, supports a role for the ESR1–CREB1–GRIN2B pathway in BPA-induced neurotoxicity, and provides mechanistic evidence for bisphenol risk assessment.

The simultaneous removal and resource recovery of uranium and organic pollutants from radioactive wastewater pose a significant environmental challenge, primarily constrained by the limited charge transfer efficiency of conventional remediation materials. This work achieves superior photoelectrocatalytic performance by engineering dual-channel charge transfer pathways in facet-exposed BiOI nanosheets. Through controlled synthesis, we construct [001]-oriented BiOI cathodes rich in surface iodine active sites and bulk oxygen vacancies, which synergistically establish separate yet interconnected channels for hole capture and electron conduction. Integrated into a solar-driven wastewater resource system (SWRS), this design enables concurrent uranium recovery and complete organic mineralization while generating electricity. The system exhibits not only ultrafast removal kinetics for target pollutants (with rate constants increased several-fold) but also continuous power output (1.42 mW cm −2 ). Excellent resistance to environmental interference and cycling stability, coupled with successful operation under natural sunlight, mark a critical step toward the practical application of this integrated system. This study demonstrates an effective strategy for achieving multifunctional integration in complex environmental remediation through precise regulation of catalyst charge transport pathways. A solar-driven system(B-SWRS) integrating a [0 0 1] facet-engineered BiOI cathode with a TiO 2 -Si photoanode, which simultaneously enables efficient UO 2 2+ recovery, tetracycline degradation, and electricity generation via enhanced charge transfer through exposed [0 0 1] facets and oxygen vacancies.

Biochar-induced interfacial defects modulate electronic structure of Mn Co spinel. • Complete IBU was removed in 5 min with an apparent reaction rate of 1.08 min −1 . • Interfacial structural defects accelerated redox cycles for boosted 1 O 2 generation. • The micropollutant was removed through a 1 O 2 dominated non-radical pathway. Spinel-based transition metal oxides are potential activators for peroxymonosulfate-based advanced oxidation processes (PMS-AOPs) in water purification, yet their sluggish redox cycling, stemming from poor conductivity, remains a critical limitation. In this work, a distiller's grain-derived porous biochar (BC)-decorated Mn Co spinel nanosheet catalyst (MnCoO x @BC) is developed and applied for PMS activation. The catalyst exhibits high efficacy in degrading ibuprofen (IBU), achieving complete removal within 5 min with an apparent reaction rate constant of 1.08 min −1 ([IBU] = 10 mg L −1 , [catalyst] = 200 mg L −1 , [PMS] = 200 mg L −1 ), which is 18 and 15 times for pristine BC and unsupported MnCoO x , respectively. Characterization and DFT calculation results indicate that the introduction of biochar could improve the conductivity and induce the formation of abundant oxygen defects, which accelerate the redox cycles of Co (III)/Co (II) and Mn (IV)/Mn (III) catalytic centers. This interfacial configuration facilitates the conversion of PMS into peroxysulfate radical (SO 5 • − ) and superoxide radical (O 2 • − ) species, and finally towards singlet oxygen ( 1 O 2 ), establishing a non-radical dominant pathway where 1 O 2 accounts for over 95% of the reactive species contribution. This work presents an effective strategy for developing defect-controlled catalytic interfaces to modulate the d-band center of metal sites and steer the interfacial electron transfer pathway, offering profound insights into non-radical-dominated mechanisms for the degradation of emerging micropollutants.

Deep hydrocarbon resources are recognized as a critical replacement domain for global oil and gas reserves. However, wellbore instability during the application of water-based drilling fluids represents a critical risk for cores, which severely constrains drilling efficiency and operational safety. Herein, a double-walled self-healing microparticles (MPSD) encapsulating epoxy monomer of bisphenol A and luteolin diglycidyl ether composite (BL-DGE) for wellbore stabilization was innovatively proposed and developed. MPSD exhibited a regular spherical morphology with a compact, dense surface, coupled with excellent thermal resistance and mechanical performance. After being immersed in an aqueous environment at 160–200 °C for 16 h, the shale slices treated with MPSD exhibit a shear strength of 634–707 kPa. Furthermore, under high-temperature immersion conditions, the shale cuttings are bonded into an integral structure by MPSD. The permeability of the artificial core treated with MPSD was reduced from 0.95 to 0.162 mD, with a plugging rate of 82.95%. The shell of the microparticles fracture under high-temperature conditions, releasing BL-DGE. By plugging the pores of the rock debris, the loose and fragmented rock is bonded into a dense and stable monolithic structure, significantly improving its mechanical properties and stability. This work provides an important theoretical foundation and technical solution for wellbore stabilization using water-based drilling fluids in deep fractured formations.

Perforated graphene-based electrochemical environmental sensor is developed. • Excellent performance is obtained for detecting bisphenol A in water samples. • Main detecting properties are elucidated in comparison. • A strategy to refine graphene-mediated electrochemical sensor is provided. Thermally perforated graphene (pGO) was prepared through the high-temperature alkaline etching to develop a sensitive electrochemical detecting platform for bisphenol A (BPA) in environmental waters. Abundant micro- and mesopores were generated, increasing the specific surface area from ∼50.0 to ∼300.0 m 2 ·g −1 and enhancing surface adsorption and charge-transfer properties. Compared to the graphene oxide-modified electrode, the pGO/GCE demonstrated superior electrochemical kinetics, evidenced by a significantly lower charge transfer resistance ( R ct) and a greater effective charge-selective area. These improvements facilitated more rapid interfacial electron transfer and reduce energy barriers. Furthermore, the diffusion coefficient ( D ) of pGO (15.6809 cm 2 ·s −1 ) was markedly higher than that of GO (0.4044 cm 2 ·s −1 ). Benefiting from these merits, the sensor exhibited robust and stable anodic signals, achieving a wide linear range of 0.5–50 μmol·L −1 (R 2 = 0.999), and a low detection limit of ∼10.0 nmol·L −1 (S/N = 3). Good selectivity was measured in practical applications, achieving recoveries of 95.4–100.2% in tap-water, secondary-water, surface-water, mineral-water and milk-powder samples. Introducing defects by thermal perforation improved mass transport, surface enrichment and electron transfer, offering a promising approach to develop high-performance electrochemical sensors for trace contaminants in environment.
