Bisphenol A (BPA) is one of the most widely produced industrial chemicals globally. Exposure to BPA has been associated with neurobehavioral disorders and various other diseases. As an endocrine disruptor, BPA primarily binds to oestrogen receptors, thereby interfering with multiple neurological functions. Despite extensive research into its disruptive effects, the neurotoxicity of BPA remains incompletely understood. This study aimed to investigate the effects of long-term BPA exposure on behavioural memory and the neurological system in adult mice. Using a combination of behavioural and morphological analyses, along with single-cell sequencing technology, we examined the sex-specific effects of BPA and its underlying neurotoxic mechanisms. In female mice, prolonged BPA exposure disrupted oestrogen signalling, leading to glial hyperplasia in the hippocampus. This, in turn, resulted in depression-like behaviours and impairments in spatial learning and memory. In male mice, chronic BPA exposure induced apoptosis of granule neurons in the hippocampal dentate gyrus, contributing to a degree of brain atrophy. These changes led to depressive and anxiety-like behaviours, impaired spatial learning, and memory, and increased susceptibility to neurodegenerative conditions. This study elucidates the cellular and molecular mechanisms underlying the sex-specific neurotoxicity of BPA. The findings not only advance our understanding of the neurological risks posed by endocrine-disrupting chemicals but also provide critical scientific evidence to support precision medicine strategies and inform chemical policy development.

Organic–inorganic composite aerogels represent a novel class of materials that effectively combine the advantages of both organic and inorganic components. Polybenzoxazine (PBz) has emerged as a promising organic alternative due to its structural rigidity, thermal stability, and cost-effectiveness. However, achieving efficient compatibility between PBz and inorganic components remains a significant challenge. In this study, inspired by the structure of diatoms, tannic acid (TA) was introduced as a compatibilizer to stabilize the dispersion of inorganic silica precursors within a PBz solution and improve their compatibility. A uniform structure with minimal phase separation was achieved through a two-step catalytic copolymerization method at room temperature. Benefiting from the inherent rigidity of PBz and superior thermal stability of polysiloxane, the resulting polybenzoxazine/silicon hybridized aerogel (BSA) exhibits a low thermal conductivity of 0.0487 W m−1 K−1, a high compressive strength exceeding 20.0 MPa, and outstanding thermal degradation stability (Td5 of 389.75 °C). This biomimetic and environmentally sustainable approach holds significant potential for advancing the development of next-generation thermal insulation materials.

Tight ultrafiltration (UF) membranes and loose nanofiltration membranes demonstrate significant potential for the efficient separation of dye/salt wastewater mixtures. However, the development of high-performance membranes suitable for industrial-scale production remains a challenge. In this study, a self-supporting tight UF membrane was fabricated for the separation of dyes and salts using a simple phase separation method. A series of carboxylate-functionalized polyaromatic ether sulfone (PAES) polymers with varying carboxylate (−COO − ) content were synthesized as hydrophilic additives to prepare polyethersulfone (PES) blend membranes. The effects of the carboxylate content in the synthesized polymer, additive blend ratio, and dope concentration on the morphology, mechanical strength, hydrophilicity, surface composition, zeta potential, and permeation and rejection performances were systematically investigated. Experimental results revealed that the − COO − content in the polymer additive is the dominant factor for achieving tight UF membranes suitable for dye/salt separation, rather than the dope concentration or blend ratio. The optimal membrane exhibited a desirable pure water permeability of 64 L·m −2 ·h −1 ·bar −1 , with a high rejection rate of 96 % for Congo red dye and a low salt rejection rate of 9.0 % for Na 2 SO 4 . Furthermore, the membrane demonstrates excellent long-term filtration stability and considerable anti-fouling properties against bovine serum albumin solutions, highlighting its promising application potential.

A series of TiO 2 -CdS composites were prepared at room temperature using a one-step precipitation method, and an appropriate loading ratio was determined. Compared with pure TiO 2 and CdS, the composites exhibited superior photocatalytic degradation performance in the degradation of ciprofloxacin (CIP) and the reduction of Cr(Ⅵ). The incorporation of an appropriate amount of TiO 2 effectively suppressed the agglomeration of CdS nanoparticles and enhanced interfacial electron transfer, thereby significantly improving photocatalytic efficiency. Furthermore, a metal ion-mediated redox synergistic system was successfully constructed, achieving efficiency breakthroughs in the degradation of bisphenol A (BPA) and ibuprofen (IBU), which exhibited negligible photocatalytic activity under conventional conditions. The influence of different heavy metal ions on the photocatalytic degradation performance of organic pollutants were discussed. This provides a robust theoretical basis for the removal and resource recovery of refractory organic compounds.

The growing complexity of water contaminants necessitates a deeper understanding of the interplay between multiple pollutants and catalytic sites. Herein, we explore the simultaneous removal of sulfamethoxazole (SMX) and monoiodoacetic acid (MIAA) via liquid-phase catalytic hydrogenation over Pd nanoparticles supported on diverse carriers (CNT, C₃N₄, Al₂O₃, and SBA-15). Although all catalysts performed well in single-component tests, only Pd/CNT exhibited robust dual-removal capability in mixed systems, achieving complete deiodination of MIAA and 92.4% reduction of SMX within 60 min. Intriguingly, a mutual interference phenomenon was unveiled: MIAA suppressed SMX reduction, while SMX (and other aromatics) unexpectedly accelerated MIAA deiodination. Mechanistic studies identified the pivotal role of hydrogen spillover on Pd/CNT, which possessed a superior H₂ uptake capacity. This facilitated the generation of surface-mobile active H that migrate to the support, enabling a binary active site mechanism. We propose a sequential pathway comprising H₂ dissociative activation, spillover, direct Pd-catalyzed deiodination of MIAA, and CNT-mediated hydrogenation of SMX via spilled-over H species. These findings highlight the exceptional promise of Pd/CNT for the remediation of complex organic contaminants and provide fundamental guidance for designing bifunctional hydrogenation catalysts.

Eliminating various organic pollutants from wastewater continues to pose a major environmental issue. Herein, CO 2 -responsive magnetic bio-aerogels (Ag/Fe-NC@DCG) integrating “smart” adsorption and photo-Fenton-like degradation were constructed by embedding surface plasmon resonance (SPR)-enhanced MOF-derived Ag/Fe nanocarbon (Ag/Fe-NC) into cellulose nanocrystal reinforced gelatin aerogels, followed by surface functionalization with a CO₂-responsive silane coupling agent ( N, N -diethyl-3-aminopropyltrimethoxysilane). The resulting aerogels exhibited outstanding adsorption capacities toward charged pollutants, reaching 859.62 mg/g for negatively charged methyl orange (MO) and 635.92 mg/g for positively charged methylene blue (MEB), governed by electrostatic interactions and hydrogen bonding. The adsorption process was well described by the Langmuir adsorption isotherm model and pseudo-second-order adsorption kinetic model. Remarkably, CO 2 served as a trigger gas to enable rapid and selective adsorption of negatively charged organic pollutants from the mixture, thereby realizing CO 2 -regulated selective adsorption. As anticipated, under visible light irradiation in the presence of peroxymonosulfate (PMS), the Ag/Fe-NC component efficiently catalyzed photo-Fenton-like reactions, leading to significantly enhancing removal efficiencies for both charged and neutral organic pollutants. For neutral bisphenol A (BPA) and amphoteric tetracycline hydrochloride (TCH) that were initially unadsorbed, their removal efficiencies rose dramatically from 5.24% and 12.79% to 90.67% and 97.40%, respectively. Additionally, the aerogels demonstrated excellent recyclability, mechanical robustness, and antibacterial activity. Overall, this work presents a versatile and sustainable aerogel platform that integrates CO 2 -triggered selective adsorption with photo-Fenton-like degradation, offering a prospective pathway for wastewater remediation.

Bisphenol A (BPA) poses significant health risks, so its selective and sensitive determination in food is crucial. Here, we report a “turn-on” persistent luminescence aptasensor using undoped zinc gallogermanate nanoparticles (ZGGO) for selective and sensitive BPA determination in aquatic products. The sensor consists of a BPA-specific aptamer-grafted ZGGO (donor) hybridized with Cy3-labeled complementary DNA (acceptor). The persistent luminescence of the aptasensor is quenched via resonance energy transfer to the acceptor in the absence of BPA, and recovered in the presence of BPA due to the competitive binding of BPA with the aptamer to release cDNA-Cy3. This design effectively eliminates autofluorescence and background interference, enhancing sensitivity and selectivity. The aptasensor gives a wide linear range (1–1000 ng L −1 ), low detection limit (0.27 ng L −1 ), high selectivity, and good precision. Spike-recovery tests in fish samples yield the recovery of 85.2%–101.6%, proving its potential for monitoring BPA in complex food matrices.

Photocatalytic three-electron oxygen reduction (3e - ORR) can convert dissolved O 2 into •OH via coupled 2e - /1e - steps, bypassing external H 2 O 2 dosing and the kinetic bottleneck of conventional photo-self-Fenton (PSF) systems. Here, Fe-substituted phosphomolybdate clusters (FePMo) are anchored on a biomass-derived hierarchical tubular carbon (HTCC) to form an HTCC/FePMo heterojunction (HFe) that drives a visible-light self-Fenton process. For tetracycline (TC, 10 mg L −1 ), HFe achieves 99 % removal within 120 min at unadjusted pH 0 = 5.8 ( k obs = 0.026 min −1 ) and 3.6–7.7-fold higher mineralization than either component, while retaining high activity from pH 3–9 and in saline water, natural surface water, and secondary effluent. In a continuous-flow reactor, an HFe/PVDF membrane (0.64 mg cm −2 loading; 2 mL min −1 , HRT 1.23 min) sustains > 90 % TC removal for 120 h. Ecotoxicity is alleviated, with inhibition-zone diameters shrinking from ∼2.3 to ∼0.8 cm ( S. aureus ) and from ∼1.25 to ∼0.7 cm ( E. coli ), and wheat-leaf Fv/Fm recovering to ∼0.73, comparable to the water control. The energy demand is low (EE/O = 0.0031 kWh L −1 ; EE/M = 0.31 kWh g −1 ), supporting a scalable, sustainable route for advanced treatment of refractory wastewater.

Bisphenols have a wide range of effects on human systems, including the reproductive, immune, and nervous systems, and have been identified as endocrine-disrupting substances. Bisphenols are also ubiquitous in the environment. Therefore, it is of great significance to rapidly and sensitively monitor and detect trace amounts of bisphenols in environmental samples. In this study, a solid-phase extraction (SPE) material—COF-DhaTph@SiO2, with a porphyrin-based covalent organic framework (COF) as the shell and silica as the core—was synthesized via a one-pot method. This material was then applied to the separation and enrichment of three bisphenols (bisphenol A, bisphenol F, and bisphenol S) in real samples. The maximum adsorption capacities for bisphenol A, bisphenol F, and bisphenol S reached 275.73 mg g−1, 252.38 mg g−1, and 122.36 mg g−1, respectively. This can be attributed to the fact that the composite material can form multiple types of hydrogen bonds with bisphenols, while the porphyrin molecules with a large π-system in the composite provide π–π stacking interactions. In addition, conditions such as adsorption time, adsorption temperature, pollutant concentration, and pH were explored and optimized. Under the optimal adsorption conditions, the limit of detection (LOD) values ranged from 0.140 to 1.010 µg mL−1, and the limit of quantification (LOQ) values were between 0.424 and 3.061 µg mL−1. The spiked recovery rates of real samples were in the range of 89.33%–97.33%. After five adsorption–desorption cycles, the maximum adsorption capacity remained above 85%, indicating that the method established using this material is suitable for the enrichment of the three bisphenols in complex samples.

While the significance of the coordination microenvironment in single-atom catalysts (SACs) is well recognized, precise modulation of the more extended coordination sphere remains a substantial challenge. Herein, a series of cobalt-based SACs (Co/TpHz, Co/TpPa, Co/TpBD) were fabricated via a secondary coordination sphere (SCS) modulation strategy. This was achieved by anchoring isolated Co sites into three β-ketoenamine-linked covalent organic frameworks (COFs) with tailored conjugation degrees in their frameworks, which resulted from the controlled variation in the number of aromatic rings within the aminobenzene-based linkers. Remarkably, the monobenzene-type Co/TpPa catalyst exhibited superior performance in the removal of bisphenol A via Peroxymonosulfate (PMS) based Fenton-like reactions, achieving an exceptional reaction rate constant ( k ) of 0.54 min −1 , which is 2.6 times and 49 times higher than those of Co/TpHz and to Co/TpBD, respectively. Density functional theory (DFT) calculations revealed that modulation of the SCS significantly influences the electronic structure of the Co sites. Notably, the active sites in Co/TpPa exhibited the strongest adsorption energy (–1.60 eV) toward PMS, along with the lowest reaction energy barrier. This work offers valuable insights into the role of the SCS in SACs and opens a new avenue for the rational design of high-performance Fenton-like catalysts.

Bisphenol analogues (BPs) are widely used industrial chemicals, raising concern regarding their potential disruption of the thyroid hormone (TH) system. This study systematically evaluated the binding properties and interference potential of 21 structurally diverse BPs toward transthyretin (TTR) and thyroxine-binding globulin (TBG). Fluorescence polarization assays showed that TTR binding was primarily driven by bridging-group rigidity, halogen substitution, and hydroxyl number, whereas TBG affinity was more dependent on molecular polarity and steric volume. Molecular docking supported the roles of halogenation and structural complementarity in stabilizing ligand-protein interactions. A quantitative in vitro to in vivo extrapolation (QIVIVE) model predicted that environmentally relevant exposure levels of most BPs cause negligible alterations in serum free T4, and mixture effects were approximately additive. Toxicological Priority Index (ToxPi) integration identified highly halogenated congeners as dominant high-risk candidates, with substantially greater potential impacts under occupational high-exposure scenarios. Overall, this work establishes a multi-tiered framework linking molecular binding characteristics to in vivo hormone perturbations, providing scientific support for evaluating TH-disrupting risks and guiding the identification of safer BP alternatives.

Silver ion was applied in paper spray ionization mass spectrometry (PSI MS) to assist the ionization of bisphenols and derivatives including bisphenol A (BPA), bisphenol B (BPB), and bisphenol A bis (allylether) (BPA-BAE). By using the silver ion assisted paper spray ionization (SIA PSI), the intensities of BPA, BPB, and BPA-BAE were improved approximately 62, 90, and 58 times under positive mode and 1900, 1980, and 23 250 times under negative mode. Linear relationships for BPA were established within the concentration range of 0.002–1 mM, exhibiting strong correlation coefficients. The limit of detection for BPA can achieve 7.4 × 10 −5 mM. BPA in plastic sample and complex biological samples were also successfully detected by SIA PSI.
