In this work, a biobased cationically photocurable omniphobic coating system was effectively developed via a facile strategy by using epoxidized soybean oil as a biomass coating precursor, tetrakis [(epoxycyclohexyl) ethyl] tetramethylcyclotetrasiloxane as an effective cross-linking agent, and polydimethylsiloxane as an omniphobic agent to provide coatings with low surface energy. Due to the rational design of this coating system, no extrinsic organic solvent was added, and 20 s ultraviolet radiation was sufficient for coating curing. The as-prepared omniphobic coatings were highly optically transparent and mechanically robust, and they also possessed exceptional liquid repellency and chemical shielding durability against various contaminants and corrosive agents. Besides, these coatings exhibited remarkable self-cleaning performance and also could be appropriately used for anti-ink, antigraffiti, and antifingerprint purposes. In addition, they could be applied for fabricating functional noctilucent coatings and bestowed them with an omniphobic property. More strikingly, this coating system could be cured via sunlight exposure without compromising the omniphobic property, enabling these coatings to be availably applicable for various substrates, including the thermosensitive ones. Therefore, the features of facile preparation, short curing duration, and optional curing strategy, in addition to above versatile functions, make these biobased omniphobic coatings tremendously promising for practical applications.

A biomimetic, fluorine-free, three-layer aqueous coating for cotton─composed of an Fe2+/Cu2+-catalyzed polydopamine (PDA) primer, a chitosan–SiO2 (CS) aerogel midlayer, and a thin polydimethylsiloxane (PDMS) overcoat─was developed to impart durable superhydrophobicity, rapid photothermal self-healing, antibacterial activity, and efficient oil–water separation. Treated cotton exhibited a static water contact angle (WCA) of 170° and retained a WCA of >155° after 2500 Martindale abrasion cycles or 30 ISO 105-C06 wash cycles; the WCA was restored to ≥160° after ambient storage or within 20 min under natural sunlight as surface temperatures approached ≈50 °C. PDA-mediated Cu2+ chelation (5 mM) produced >99% inhibition of Escherichia coli and Staphylococcus aureus; gravity-driven oil–water separation efficiencies exceeded 98% with >96% retention after 12 cycles. Preliminary scalability and environmental impact analyses, including material inventories and PDMS release estimates, support the potential for industrial translation. This fluorine-free, beetle-exoskeleton-inspired strategy offers a scalable route to multifunctional, sustainable textile finishing and environmental remediation.

With the development of industrialization, the discharge of oily wastewater has been increasing significantly. In this study, a novel bio-based oil–water separation membrane was developed using bio-based Polyamide 56 (PA56) as the matrix material, which was modified by incorporating hydroxylated boron nitride nanosheets (BNNS-OH) through a blending approach. The PA56/BNNS-OH composite nanofiber membrane was fabricated via electrospinning. The impact of adding BNNS-OH on the morphological structure, selective permeability, and oil–water separation performance of the composite nanofiber membrane was explored. The results showed that, the introduction of BNNS-OH increased the surface roughness of the nanofiber membrane, forming a micro-nano nodular structure. This not only significantly enhanced the membrane’s hydrophilicity but also endowed it with outstanding underwater superoleophobicity. The M−3 membrane, prepared with 5 wt% BNNS-OH relative to PA56 content, exhibited superhydrophilic/underwater superoleophobic properties. It demonstrated efficient separation performance for various types of surfactant-stabilized emulsions (SSEs), with a separation efficiency of 99.84% for n-hexane-based SSE, approaching complete separation. Moreover, the membrane exhibited excellent cycling and thermal stability, chemical resistance, and self-cleaning properties under complex conditions. This study provides new insights and methods for developing novel bio-based and environmentally friendly oil–water separation membranes, which hold significant potential for application in oily wastewater treatment.

Complex pollutants in wastewater, such as recalcitrant oils, organic dyes, and antibiotics, have posed significant environmental challenges that adversely affect ecosystems and human health. Herein, we successfully fabricated hierarchical bioinspired polyacrylonitrile (PAN)/Zein/bismuth oxychloride (BiOCl) fibrous membranes featuring ultrafast liquid transport channels and petal-textured energy conversion layers by integrating centrifugal spinning with the in-situ growth of BiOCl nanosheets. The membranes demonstrate an exceptional capability to treat oil/water mixtures and simultaneously remove soluble dyes, thereby offering a viable solution to the issues mentioned above. The strategic construction of liquid channels, coupled with the BiOCl photocatalytic layers, optimized the water transport pathway in the oil/water mixture and facilitated the formation of an effective hydrated anti-fouling layer, achieving a separation flux as high as 6498 L·m −2 ·h −1 . Additionally, the membranes exhibited outstanding pollutant degradation performance, with removal efficiencies of 94.1 % for Rhodamine B and 64.5 % for TC-HCl. This work comes up with new insight for the rational design of multifunctional fibrous membranes, opening a window for the prospect of treating environmental wastewater.

Traditional oil/water emulsion separation membranes often fail to maintain long-term stability and regeneration due to inadequate fouling resistance and low self-cleaning efficiency in practical applications. This study developed a superhydrophilic nanofiber membrane with a micro/nanolayer architecture and piezoelectric photocatalytic properties by combining polyacrylonitrile (PAN), polyethyleneimine (PEI), and silver-modified barium titanate (Ag-DBT). This membrane can effectively separate oils and dyes from complex emulsions, demonstrating high water permeation flux of 2492 L·m −2 ·h −1 , along with exceptional oil separation efficiency (~99 %) and dye adsorption (~99 %). In addition, the PAN-PEI/Ag-DBT membrane demonstrated an ultra-high degradation efficiency of approximately 99 % for methyl blue (MB) within 90 min. Notably, owing to the piezoelectric photocatalytic properties of Ag-DBT, the PAN-PEI/Ag-DBT nanofiber membrane maintained exceptional self-cleaning performance even after high contamination. To assess the self-cleaning performance and cycling stability of the PAN-PEI/Ag-DBT membrane, we conducted cyclic recovery experiments across three conditions: oil-in-water emulsions, dye-water solutions, and oil-in-dye-water emulsions. In the first three self-cleaning cycles, the self-cleaning membrane demonstrated water flux recovery rates that exceeded 90 % and irreversible fouling rates that were below 10 %. This research provides new insights into the advancement of multifunctional self-cleaning membranes.

Nanofibrous membranes are considered ideal candidates for water purification. However, the membrane fouling results in an irreversible decline in separation flux, while the slippage of nanofibers leads to an increase in pore size under driving pressure, subsequently inducing a decline in separation efficiency. Rational structure design and material selection are crucial for separation performance improvement. In this study, we report double-layer hierarchical structured nanofibrous membranes that demonstrate simultaneous superhydrophilicity and underwater superoleophobicity for oil-water separation via a combination of electrospinning and seed-mediated solvothermal strategy. The double-layered hierarchical structure comprises an upper layer of ZIF-8@PMIA composite nanofibers and a bottom layer of PMIA nanofibers. Notably, the incorporation of ZIF-8 species confers several advantages, such as increased surface roughness, reduced pore size, and enhanced superhydrophilicity, collectively contributing to superior anti-fouling performance and high separation efficiency. Meanwhile, the bottom PMIA nanofibers, with larger diameters, ensure robust mechanical integrity for the entire membrane. Due to the rational structural design, the membrane achieves outstanding separation performance, including a 99.91 % separation efficiency for diesel-in-water emulsions and an ultrahigh flux of 3821.7 L m − 2 h −1 for dichloromethane-in-water emulsions. Therefore, this membrane has broad application prospects in the oil–water separation field.

Oil spills and organic solvent discharges pose serious ecological and environmental risks, necessitating the development of highly efficient oil/water separation materials. Herein, we designed and prepared a novel ultra-light aerogel, namely hydrophobic reduced graphene oxide/polyvinyl alcohol@carbon delignified wood aerogel (H-rGO/PVA@CDWA), for this purpose. In particular, we integrated a delignified wood aerogel with graphene oxide (GO) and PVA. Subsequent carbonisation at 500 °C and treatment with methyltrichlorosilane yielded a material that could be recycled through combustion or extrusion. The H-rGO/PVA@CDWA retained the anisotropic three-dimensional pore structure of wood, exhibiting good mechanical properties and fire resistance. The material also showed considerable hydrophobicity (water contact angle = 139.42°) and excellent adsorption capacity towards various oils (6.5041–17.8426 g/g). Notably, the material maintained a high adsorption capacity and satisfactory elasticity after 20 extrusion–adsorption cycles and 10 combustion–adsorption cycles. Furthermore, the material exhibited a high oil/water separation efficiency for various emulsions and a considerable capacity for continuous oil/water separation. The material preparation strategy proposed herein has broad application prospects for wood utilisation in oily wastewater treatment, oil pollution remediation and organic solvent recovery.

The utilization of solar energy for desalination and irrigation has emerged as an effective strategy. However, most traditional evaporators are constrained by single-sided light absorption and internal blockages caused by salt or oil accumulation. These issues significantly impede their light absorption efficiency and recycling capabilities. To overcome these limitations, we propose a novel double-sided light-absorbing 2.5D evaporator. Both the upper and lower layers of this evaporator are composed of porous carbon nanofilms specifically designed for efficient photothermal conversion. The nanostructured surface substantially enhances the optical path of sunlight, creating a light-trapping effect that improves light absorption. Additionally, an interlayer hydrophilic membrane is integrated to facilitate upward water transport, synergistically enhancing evaporation efficiency in conjunction with the double-sided light-absorption structure. Determining the optimal working angle is crucial for maximizing the evaporator’s performance. At the optimal tilt angle, it achieves an evaporation rate of 3.43 kg m − 2 h −1 . By leveraging its double-sided design and tunable film wettability, the 2.5D evaporator demonstrates remarkable capability in separating salt-resistant and oil–water emulsions. Furthermore, it exhibits exceptional stability, maintaining a high evaporation rate during cyclic testing. These findings confirm its outstanding purification performance for treating oily wastewater or seawater, offering a practical solution to address irrigation challenges.

The hydrophobic long-chain coupling agent, γ-aminopropyltriethoxysilane (KH550), was selected for the modification of ZIF-67 to create hydrophobic imidazole metal-organic frameworks (MOFs) composites, designated as SA/ZIF. The study reveals that the modified SA/ZIF exhibits substantial enhancement in surface wettability, achieving a water contact angle (WCA) of 123.2 ± 2°, in stark contrast to the original ZIF-67, which displayed a WCA of 0°. Additionally, the research involved coating an in-situ synthesized ZIF/MS sponge with a KH550 hydrophobic emulsion through dip-coating to enhance surface roughness and reduce surface energy, successfully creating hydrophobic SA/ZIF/MS sponge composites. This material exhibits excellent water resistance, with a WCA of 157.6 ± 2°, effectively separates oil/water mixtures with a separation efficiency of 99 %, and results in a filtrate with a water content of <10 ppm after separation. Furthermore, the material shows outstanding adsorption capacity for eight different oils and organic solvents, ranging from 54.1 g/g to 140.1 g/g. The article also details the synthesis, characterization, and performance of the material in oil-water separation applications.

With the increasing complexity of wastewater, the development of catalytic membranes featuring heterojunctions of catalysts combined with advanced oxidation techniques has become a promising approach for wastewater treatment. This study prepared a heterostructured bimetal-based polyetherimide (PEI) catalytic membrane (HBPCM) via electrospinning and in-situ growth. The Z-type heterojunction of FeOOH and ZnO enhanced electron mobility, reducing photoluminescence intensity, Nyquist arc radius, and increasing photocurrent response, thereby improving redox and photocatalytic performance. Integrating photo-Fenton and membrane processes facilitated dynamic catalytic reaction, enhancing pollutant degradation through improved mass transfer. The photo-Fenton degradation of HBPCM for methyl orange (MO), orange G (OG), methylene blue (MB) and phenol (phOH) in static experiments reached 96.6 %, 87.5 %, 92.3 % and 95.7 % within 10 min, which were much higher than that of iron-based PEI catalytic membrane (IPCM) or zinc-based PEI catalytic membrane (ZPCM) in single photocatalysis or Fenton catalysis process. In dynamic experiments, photo-Fenton efficiency of HBPCM for MO, OG, MB, and phOH in 10 min was 8.55, 8.25, 6.86, and 2.69 times higher than in static conditions. Furthermore, loading FeOOH/ZnO conferred superhydrophilicity to the membrane, enhancing oil-water separation performance. Combining membrane technology with photo-Fenton catalysis offers an effective approach for treating complex wastewater.

Background Alcoholic liver disease (ALD) poses a major global health challenge, with limited effective interventions. The Dampness-Heat Regulating Formula (DRF), a traditional Chinese herbal tea composed of nine edible medicinal herbs, has shown promise in mitigating alcohol-induced liver injury. This study aimed to identify its core active components and elucidate underlying mechanisms. Methods Active compounds were retrieved from multiple databases and screened using chemical similarity, target prediction, and ADMET filtering. Disease-related targets were identified through public transcriptomic datasets. Three machine learning algorithms—random forest, support vector machine, and LASSO—were used to prioritize therapeutic targets. High-throughput molecular docking and virtual screening were combined with untargeted metabolomics to identify candidate compounds. The interaction between oleanolic acid (OA) and AKT1 was further verified by cellular thermal shift assay (CESTA). In vitro and in vivo assays were conducted to validate hepatoprotective effects. Additionally, the content of OA in DRF was quantified by HPLC to assess the relevance of experimental dosing. Results A total of 690 candidate compounds and 33 ALD-associated targets were identified. AKT1 emerged as the top-ranked hub target. OA showed strong binding affinity to AKT1, and CESTA confirmed their direct interaction. Functional assays demonstrated that OA alleviated ethanol-induced damage in hepatocytes and zebrafish models. HPLC analysis confirmed that DRF contained physiologically relevant concentrations of OA, supporting the translational relevance of the selected doses. Conclusion This study reveals a potential AKT1-centered mechanism through which DRF protects against ALD and identifies oleanolic acid as a bioactive compound with dual computational and experimental validation. It offers a scientific basis for integrating traditional herbal formulas with modern drug discovery approaches in the prevention of alcohol-related liver injury.

Petroleum operations produce emulsified oil-water mixtures that pollute the environment. Efficient oil recovery and wastewater purification are crucial. Extreme-wettability single-channel separators often form barrier layers from intercepted phases, reducing efficiency and flux stability. In this study, a composited sponge (HO-HL@MS) with dual oil-water channels was constructed by stepped-interlocking of a superoleophilic/superhydrophobic torus frustum sponge and a superhydrophilic/oleophobic circular frustum sponge. During the demulsification separation of oil-in-water emulsions, the superhydrophilic/oleophobic component facilitates emulsion demulsification and allows the aqueous phase to permeate, while the superoleophilic/superhydrophobic section enables timely discharge of clogging oil phases, conversely for during water-in-oil emulsions. This synergistic “demulsification-removal” mechanism allows simultaneous oil and water discharge, fundamentally resolving the issues of clogging and flux attenuation caused by the retention of the intercepted phase in traditional single-channel systems. It demonstrates excellent demulsification efficiency for both water-in-oil and oil-in-water emulsions. For water-in-oil emulsions, a permeation flux above 3000 L·m −2 ·h −1 with a separation efficiency exceeding 97.9 % after continuously processing 800 mL was achieved. For oil-in-water emulsions, a flux over 6000 L·m −2 ·h −1 with efficiency higher than 98.9 % was obtained. When treating industrial emulsions with high water content (60 % aqueous phase), it retained 98.37 % separation efficiency and a flux of 1803 L·m −2 ·h −1 for water-in-oil systems, and 98.6 % efficiency with a flux of 7279 L·m −2 ·h −1 for oil-in-water systems, demonstrating exceptional anti-fouling capability and industrial application potential. The composited sponge achieves efficient, stable, and long-term separation of various oil-water mixtures, emulsions, and industrial-grade emulsions, thus providing a new strategy for complex emulsion separation.
