Addressing the persistent bottlenecks of low efficiency, high costs, and complex fabrication in large-scale oil-in-water emulsion separation, especially for submicron emulsions where environmental compatibility and performance further degrade, this work introduces a cost-effective, biomass-derived separation layer, a straw-based gel membrane (SBGM), that emphasizes green design and functional integration. Fabricated via simple straw pretreatment and surface modification under solvent-free conditions, the SBGM is produced through an entirely green and straightforward route: one-step regeneration of straw cellulose to form gel spheres and a supporting matrix, followed by surface coating with a blended PVA/TiO 2 functional layer. Featuring a lotus-leaf-inspired bionic structure and abundant hydrophilic groups, the membrane exhibits superhydrophilicity (WCA = 0°) and underwater superoleophobicity (UOCA = 162°), together with exceptional durability and stability against acids, alkalis, and extracellular polymers in wastewater. Critically, it delivers over 99 % separation efficiency across diverse submicron oil-in-water emulsions and maintains stable performance over repeated cycles, with a flux recovery rate of approximately 90 % and a fouling deposition ratio of approximately 30 %. Moreover, the photosensitive properties of TiO 2 confer superior hydrophilicity and self-cleaning capability, enabling the SBGM to sustain over 99 % separation efficiency even when treating real kitchen wastewater. Collectively, these advances markedly enhance the SBGM's practical potential for submicron oil-in-water emulsion separation.

In this work, the novel multifunctional electrospun trimethoxy (1H,1H,2H,2H-heptadecafluorodecyl)silane (TMHFDS)/Ag-TiO 2 /polyvinylidene fluoride (PVDF) mats were prepared. In the preparation process, the AgNO 3 was reduced to be the Ag nanoparticle and then in situ deposited on the TiO 2 nanoparticle to form the Ag-TiO 2 hybrid, which was used as the filler to fabricate the electrospun Ag-TiO 2 /PVDF mats followed by the TMHFDS modification. The successful preparation of the electrospun TMHFDS/Ag-TiO 2 /PVDF mats were proved by the characterizations of scanning electron microscopy, two-dimension energy-dispersive X-ray spectroscopy mapping, Fourier transform infrared spectroscopy, differential scanning calorimeter, and wide-angle X-ray diffraction. The electrospun TMHFDS/Ag-TiO 2 /PVDF mats possessed not only the enhanced crystallinity degree and useful piezoelectric β-crystal content of PVDF than those of the PVDF solid film and the electrospun PVDF mat but also the photocatalytic degradation ability for the oil red O dye. Moreover, for the electrospun TMHFDS(3%)/Ag-TiO 2 (30%)/PVDF mat, its water contact angle reached as high as 156.4° which was 24.6° higher than that of the electrospun PVDF mat before the TMHFDS modification, and its oil absorption capacities for valorous oils ranged between 16.3 g g −1 and 25.1 g g −1 , exhibiting the well oil–water separation ability.

Nanofibrous membranes have great potential for treating oily wastewater. However, the random stacking of nanofibers during the electrospinning process resulted in a broad pore size distribution and reduced separation efficiency. Moreover, for oil-in-water emulsions stabilized by ionic surfactants, the small oil droplets deform under the applied pressure and are squeezed into the membrane pores, leading to a decrease in flux and fouling. In this work, we developed superhydrophilic nanofibrous membranes with demulsification properties via electrospinning and a solvothermal seed-induced method. Notably, the incorporation of ZIF-8 nanoparticles offers multiple advantages, such as reducing membrane pore size, increasing the surface roughness, and enhancing membrane surface charge. These features synergistically improve both separation selectivity and demulsification properties. As a result, the membrane exhibits outstanding separation performance, achieving a separation efficiency of 96.37% for diesel-in-water emulsions and a high permeation flux of 4100 L m −2 h −1 for dichloromethane-in-water systems. This work provides an effective strategy for developing high-performance membranes for oil-in-water emulsions separation applications.

Long-term discharge of industrial oily wastewater and frequent oil spills create an urgent demand for high-performance oil-water separation membranes. Conventional membranes are limited by high cost, poor stability, and a trade-off between separation efficiency and recyclability. Meanwhile, massive waste PET plastics trigger severe environmental pollution and resource loss. Herein, waste PET bottles are recycled to fabricate porous electrospun nanofiber substrates, followed by spray-coating nano-silica/epoxy hydrophilic composite layers to obtain superhydrophilic/underwater superoleophobic PET-SE membranes. Combined FTIR, XPS, SEM and EDS characterizations verify successful epoxy grafting and uniform SiO₂ immobilization, with abundant hydrophilic amino, amide and siloxane groups enriched on fiber surfaces. Mechanical tests show the tensile stress rises from 0.78 MPa to 2.3 MPa after modification. The optimized PET-SE3 achieves an ultrahigh water flux of 12756.91 L·m⁻²·h⁻¹ . Its separation efficiency exceeds 98% for six types of immiscible oil-water mixtures, and oil rejection surpasses 90% for corresponding oil-in-water emulsions. After 30 separation cycles, oil rejection remains above 98%, and the membrane exhibits excellent chemical and structural stability. This work realizes resource recovery of waste PET. The PET-SE membrane integrates superior separation performance, robust reusability and scalable eco-friendly preparation, presenting a promising candidate for practical oily wastewater treatment.

A core–shell magnetic surface molecularly imprinted polymer (MIP) was synthesized using chitosan-modified Fe 3 O 4 nanoparticles (Fe 3 O 4 @CS) as the support and Schisandrol A as the template for selective recognition. After optimization of adsorption conditions, static and dynamic binding experiments demonstrated high selectivity toward Schisandrol A, with an imprinting factor of 4.556. Based on this material, a magnetic solid-phase extraction coupled with high-performance liquid chromatography (MSPE–HPLC) method was established for the enrichment and quantitative determination of Schisandrol A in Schisandra chinensis , achieving a limit of detection of 0.59 ng/mL and a limit of quantification of 2.47 ng/mL. The practical applicability of the MIP was further evaluated by selectively depleting Schisandrol A from the herbal extract, followed by assessment of hepatoprotective activity using an ethanol-induced fatty liver zebrafish larva model. Comparative analysis of hepatic lipid accumulation and biochemical markers (AST, ALT, and SOD) revealed that removal of Schisandrol A significantly reduced the hepatoprotective efficacy of the extract, confirming its functional contribution. These results demonstrate that the proposed MIP-based MSPE–HPLC strategy provides a robust analytical tool for selective lignan analysis and enables component-specific functional evaluation in complex herbal systems.

As one of the remote sensing abilities, electrolocation allows organisms to hunt, navigate, and interact with the environment by sensing electric fields. Mimicking this capability in artificial systems will provide a powerful strategy for remote object detection and inspection. However, current artificial approaches are restricted to conductive medium or charged targets, while electrolocation of uncharged targets in the non-conductive medium has not been achieved yet. In this work, an electrostatic interfacial enhancement-based electrolocation system (EIEEs) that fundamentally expands the scope of artificial electrolocation is proposed. Inspired by the electric organs of elasmobranch fish and the mechanosensory setae of insects, EIEEs employs electret materials as the electrostatic source and high-permittivity droplets as mechanosensory structures, locating objects with permittivities different from the medium. The proposed EIEEs can effectively detect uncharged solid/liquid objects without electrical connection, signal processing, or external power supply. Importantly, EIEEs also demonstrates the capability to detect multiple buried defects in objects, including gas in liquids, solid in liquids, liquid in liquids, and gas in solids, which has been largely unexplored in previous electrolocation systems. As a general-purpose remote sensing system for both surface and subsurface inspection, EIEEs can potentially provide a complementary modality for diverse scientific and technological domains.

Although membrane separation technology has been widely used for oily wastewater treatment in recent years, surface fouling still poses a great threat to application. Due to the strong adsorption of oil droplets onto membrane surface and within pores, pristine membranes are inadequate for long-term oil-water separation applications. Here, a novel photocatalytic nanofiber membrane via microchip grafting with in-situ mineralization was proposed. N-Methylolacrylamide (NMA) was successfully grafted on polyvinylidene fluoride (PVDF) by microfluidic electrospinning, and the grafting amount was 9 times that under conventional bottle reaction conditions. The in-situ mineralization time via the polyphenol-metal network was reduced from 27 h to 18 h, while the mineralization rate increased by threefold compared with the bottle-grafted membrane. For oil-water emulsion separation, the developed PVDF-g-NMA@FeOOH membrane successfully showed the high permeability of 38870 L·m −2 ·h −1 ·bar −1 with the outstanding rejection rate of 99.2%. It displayed great photocatalytic self-cleaning performance, and the flux recovery rate was up to 95.8% after cycle tests. Methhyllene blue (MB) removal rate reached 96.3% in 50 min. The developed membrane holds great promise for applications in oil-water separation and organic contaminant degradation.

The rising prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD)-associated hepatocellular carcinoma (HCC) is a growing global concern, with environmental pollutants implicated in its progression. 2,2′,4,4′-tetrabromodiphenyl ether (BDE 47) exhibits hepatotoxic potential, but its role in MASLD-to-HCC progression remains unclear. Here, we investigated the association between BDE 47 and MASLD using data from the National Health and Nutrition Examination Survey and explored the potential mechanisms through network toxicology and multiomics analyses. Individuals with higher serum BDE 47 levels showed positive associations with MASLD and advanced fibrosis. Network toxicology predicted that BDE 47 perturbed lipid metabolism, inflammation, and oxidative stress, thereby contributing to malignant progression. In vitro, integrated lipidomic and transcriptomic analyses revealed that BDE 47 disrupted lysosome, sphingolipid, and cholesterol metabolism, leading to lipid accumulation. Additionally, BDE 47 exposure enhanced inflammatory response, oxidative stress, and the development of immunosuppressive environment, which may facilitate MASLD-to-HCC progression. Pharmacological experiments further demonstrated that increased sphingolipid synthesis and impaired cholesterol efflux played important roles in BDE 47-induced lipid accumulation. Notably, only the parent BDE 47 compound was detected in exposed cells. Collectively, these findings provide mechanistic evidence of the carcinogenic potential of BDE 47 and its role in liver disease progression.

The escalating discharge of oily wastewater presents a considerable threat to both ecological systems and human health, making the development of efficient treatment technologies an ongoing challenge. This study constructed binary composite membranes that effectively integrate polymeric and metallic substrates by integrating a polyvinylidene fluoride (PVDF) membrane with an acid-etched copper mesh (CM). The binary composite membranes were subsequently modified with a polydopamine/polyethylenimine (PDA/PEI) complex to produce superhydrophilic and underwater superoleophobic PVDF/mesh binary composite membranes (PP@PVDF/triethyl phosphate (TEP) n -roughened CM (RCM)). By varying the mass ratio of PVDF to the solvent TEP, the phase separation kinetics were systematically regulated, resulting in five distinct membranes with tailored pore sizes and porosity levels. Among these, PP@PVDF/TEP 30 -RCM exhibited outstanding separation performance for various immiscible oil–water mixtures, achieving separation efficiencies exceeding 99.60% and reaching a maximum of 99.97%. When applied to the separation of surfactant-stabilized oil-in-water emulsions under gravity-driven conditions, PP@PVDF/TEP 30 -RCM demonstrated high permeation fluxes, all above 1010 L·m −2 ·h −1 , coupled with separation efficiencies exceeding 99.10%. Furthermore, PP@PVDF/TEP 30 -RCM maintained high separation efficiency over 15 repeated cycles. The PVDF/mesh binary composite membranes developed in this work combine high separation efficiency with robust durability, making them promising candidates for the sustainable separation of challenging oil/water emulsions.

Nanofiltration (NF) membranes show superior ion selectivity, which, however, decreases with temperature owing to excessive pore expansion of the selective layers. Herein, an effective and feasible co -solvent strategy is proposed to improve the thermostability of polyamide NF membranes. The co -solvent systems with low interfacial tension accelerate the interfacial diffusion of aqueous monomers during the interfacial polymerization. Moreover, the enhanced compatibility between the organic phase and the nascent polyamide layer, which is assessed by the Hansen solubility parameters, facilitates the formation of selective layers with high cross-linking degree. The resultant compact selective layers possess enhanced thermostability. The optimized NF membrane exhibits a high permeance of 24.8 L·m −2 ·h −1 ·bar −1 with 98.3% MgSO 4 rejection at 85 °C. The present method shows great potential for preparing thermostable NF membranes.

Surface hydrophilization is an effective antifouling strategy for membranes. However, it still faces foulants adhering and migrating, leading to irreversible performance decline. Here, inspired by the micro/nano-textured protrusions of the Nepenthes peristome, we proposed a synergistically antifouling strategy combining a stable hydration layer with a physical barrier. Hydrophilic SiO 2 nanoparticles and tea polyphenol (TP) were incorporated via microfluidic electrospinning to construct a superhydrophilic nanofiber membrane. The introduced SiO 2 constructed micro/nano- rough structures as a physical barrier while a stable hydration layer of TP was formed. Molecular dynamics simulations confirmed the robust interfacial binding through a dense hydrogen-bond network. The modified membrane displayed the great permeance of 25,462 L·m -2 ·h -1 ·bar -1 with 99.9 % oil rejection for separating soybean oil-in-water emulsion and the flux recovery ratio was 95.06 % after 300 min. This work provided a general design principle for antifouling interfaces with potential applications in environmental, energy, and biomedical.

The frequent occurrence of oil spills has resulted in increasingly serious consequences in terms of economy and environment, which to some extent hinders the green development of the social economy. Emergency measures must be taken to minimize the harm caused by oil spills. Therefore, we used a solvothermal method to synthesize a fluorine functionalized metal organic framework decorated hydrophobic sponge, in order to address the drawbacks of oil spills. This hydrophobic sponge is known as MS@UiO-67-F4. It has a multistage pore structure and low surface energy, exhibiting remarkable hydrophobicity, high adsorption of oils, and excellent reusability performance. Meanwhile, MS@UiO-67-F4 exhibits excellent adsorption capacities toward oils and organic solvents, ranging from 82.2 to 179.3 g/g. Its adsorption performance is 1.08–1.32 times that of MS@UiO-67, surpassing that of many other reported hydrophobic sponge materials. The oil-water separation efficiency reaches over 98.0%. MS@UiO-67-F4 demonstrates good durability and stability, further enhancing its effectiveness, extending its service life, and expanding its application range. In summary, MS@UiO-67-F4 has brought new opportunities and possibilities for solving the problem of oil spills.
