In response to the increasingly complex composition of industrial oily wastewater, the design of multifunctional separation materials capable of achieving phase-selective separation and efficient demulsification has become a major research focus. This study employed electrospinning to fabricate a novel nanofibrous membrane. The membrane was prepared from a blend containing the rationally designed, pH-responsive triblock copolymer poly(4-vinylpyridine)- block -poly(2-hydroxyethyl methacrylate)- block -poly( tert -butyl methacrylate) (P4VP- b -PHEMA- b -P t BMA) and polyacrylonitrile (PAN). The resulting membrane exhibits a unique bidirectional separation capability, allowing for the controlled separation of either light or heavy oil-water mixtures by simply adjusting the pH of the aqueous environment. It achieves a maximum oil-phase flux of up to 12,800 L/(m 2 ·h) with 98.8% separation efficiency, while maintaining a stable water-phase flux around 8500 L/(m 2 ·h) and efficiencies above 99%. Furthermore, the membrane was capable of effectively disrupting and separating stable water-in-oil and oil-in-water emulsions. Across repeated tests with diverse oil-water systems, the membrane consistently demonstrated high flux, high separation efficiency, and excellent cycling stability, highlighting its great potential in the design of intelligent separation materials and the treatment of complex wastewater.

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.

With the rapid development of the aviation industry, the environmental pollution caused by lubricant leakage is becoming increasingly prominent. Developing a multifunctional material with efficient separation performance and good environmental adaptability is of great significance for solving the problem of oily wastewater pollution in the aviation industry. In response to this demand, this study prepared a superhydrophobic multifunctional composites LDH-coffee biochar coating (LCBC) based on layered double hydroxides (LDH) and coffee biochar (CB) through hydrothermal synthesis, and innovatively sprayed it on a nonwoven fiber-based membrane to construct a separation material with micro-nano hierarchical structure. The material exhibits stable hydrophobicity with a water contact angle of 159.3°, a gravity-driven oil-water separation flux of approximately 800 L·m⁻²·h⁻¹, and an oil removal efficiency of ∼95%. In addition to oil-water separation, LCBC demonstrates supplementary dye adsorption capability, achieving a methyl orange adsorption capacity of 17.8 mg/g. In addition, this study adopted a photothermal assisted cleaning strategy, which significantly improved the reusability of the material by enhancing local photothermal effects to reduce oil adhesion. This study not only provides an efficient and environmentally friendly solution for controlling aviation lubricating oil leakage pollution, but also expands the potential application of superhydrophobic materials in the collaborative treatment of complex pollutants.

Recently, the silicon quantum dots (SiQDs) were widely utilized in enhanced oil recovery (EOR) due to their ultrasmall size, high specific surface area and excellent dispersion stability. Herein, the amphiphilic pH responsive silicon quantum dots (AR-SiQDs) were synthesized via the mild method to stabilize smart Pickering emulsion. Both the carboxyl and cinnamyl aldehyde were successfully grafted on the AR-SiQDs surface as hydrophilic and hydrophobic responsive groups, respectively. The structure of AR-SiQDs was characterized by Fourier transform infrared spectrometer and X-ray photoelectron spectroscopy, and the response mechanism was demonstrated via the zeta potential and interfacial tension (IFT) analyses. The results revealed that the diffusion and adsorption behaviors of AR-SiQDs relied on the protonation/deprotonation of carboxyl and reversible dynamic covalent bonding of imines. Specifically, the AR-SiQDs reduced the oil/water IFT from 51.00 mN/m to 7.58 mN/m at pH of 10.09, whereas the IFT only decreased to 24.12 mN/m at pH of 4.26. The AR-SiQDs effectively emulsified oil at alkaline condition, while the demulsification was rapidly achieved in 30 min upon the addition of hydrochloric acid. The emulsion exhibited excellent recyclability to maintain small average droplets size (from 1.42 μm to 2.12 μm) after five emulsification/ demulsification cycles. The core flooding experiments indicated that the AR-SiQDs stabilized emulsion evidently enhanced oil recovery by 14.65% at pH of 10.09, highlighting the remarkable synergistic effect with alkali. The work provided the novel strategy for designing smart SiQDs and recyclable emulsions for EOR.

The poor bleachability of eucalyptus chemi-mechanical pulp (CMP) is widely recognized as a major challenge in the industry. In order to overcome these challenges, a novel and eco-friendly Hydro-Brightening Pretreatment (HBP) strategy is proposed, with the objective of enhancing the brightness of eucalyptus through the removal of bioactive lumen extractives (LEs) using hot water. The majority compositions of LEs are characterised as ellagic acid, taxifolin and caffeic acid. The disruption of chromophore formation is evidenced by the removal of these LEs. During the bleaching reaction, ellagic acid is converted into quinonoid rings via elimination reactions, and taxifolin is oxidised to form trihydroxy benzoic acid and dicarboxylic acids, while caffeic acid undergoes esterification. In comparison with the LEs retained strategy, the implementation of HBP resulted in an enhancement of the brightness of 2.53% ISO for Eucalyptus grandis CMP, and reached a brightness of 80.85% ISO for Acacia crassicarpa Benth. CMP. Concurrently, the LEs of Eucalyptus grandis manifest notable antioxidative capacity (IC 50 =36.13 for DPPH radical). Consequently, this work provides a strategy that simultaneously enhances CMP bleachability and explores the possibility of extracting high-value antioxidant products from LEs, offering new insights on improving CMP bleachability and potential added-value co-products.

Alkaline earth lithoaluminates with the UCr4C4-type structure have demonstrated considerable potential in achieving narrow-band emissions from Eu 2+ . However, obtaining single-phase powder samples with green-emitting remains challenging. In this study, we address this issue by co-doping Ba 2+ into the novel UCr4C4-type system Sr5/6-xBaxLi17/6Al7/6O4:Eu 2+ , which significantly enhances phase purity and structural homogeneity. This approach not only reduces the emission bandwidth from 66 nm (2241 cm -1 ) to 51 nm (1830 cm -1 ) but also induces a blue shift to 529 nm, fine-tuning the emission into the desired deep green region. Through detailed mechanistic studies-including low-temperature spectroscopy and luminescence decay analysis-we identify the presence of multiple Eu 2+ emission centers associated with distinct Sr 2+ sites. Ba 2+ doping is shown to promote dominant Eu 2+ emission in the green spectral region, thereby facilitating spectral narrowing.The optimized phosphor achieves a high absorption efficiency of 64.6% and an external quantum yield of 22.2%. When integrated into a white LED prototype, it enables a color gamut covering 97.6% of the NTSC (National Television System Committee) standard, outperforming a commercial β-SiAlON:Eu 2+ -based device. This study provides an effective cationic codoping strategy for designing high-performance narrow-band oxide phosphors and highlights a promising candidate for nextgeneration display technologies.

Bacterial infections at wound sites impede healing and pose a serious threat to human health. Conventional antibiotic therapies, however, tend to trigger resistance. Consequently, copper (Cu)-based materials have recently emerged as highly promising alternatives that synergistically kill bacteria and thereby accelerate wound healing. Herein, we developed a core–satellite nanomedicine (PZH) composed of a degradable Cu-doped phosphate-based glass (PBG) core and multiple ZIF-8/hyaluronic acid (HA) satellites. PZH shows pH-triggered behavior: at physiological pH its structure remains intact and Cu2+ release is minimal, whereas the acidic microenvironment of infected wounds triggers disassembly, releasing Cu2+ and generating •OH radicals through peroxidase-like (POD-like) activity. This dual-functional ionic-catalytic mechanism achieves potent bactericidal effects against both Gram-positive and Gram-negative bacteria. At 6 μg/mL, PZH eliminates >99% of Staphylococcus aureus. In vitro assays further confirm that PZH is cytocompatible and accelerates cell migration. To overcome the application limitations of conventional Cu nanoparticle suspensions, PZH was loaded into a thermosensitive F127 hydrogel to yield PZHF, which preserves the POD-like activity and enables minimally invasive, injectable delivery to irregular wound geometries. In vivo tests further demonstrated that the biocompatible PZHF hydrogel displayed good antibacterial properties and promoted wound healing. As a smart, clinically translatable Cu-based nanomedicine, this system provides a precision therapeutic strategy for treating bacterially infected wounds.

Develop AlCl 3 -assisted mechanochemical strategy enabling efficient one-pot conversion of recalcitrant cellulose to HMF. • Synergistic interplay between Lewis acidity and mechanical stress disrupts H-bonding networks and lowers crystallinity, markedly enhancing the chemical reactivity of cellulose. • Optimization of the Brønsted/Lewis acid balance by controlled HCl addition achieves a high HMF yield of 62.8% from mechanochemically pretreated cellulose. • This green and scalable approach can be broadly extended to diverse lignocellulosic biomass wastes, including waste paper, corncob residue, bamboo powder, and corn straw, to efficiently produce HMF. 5-Hydroxymethylfurfural (HMF) is a pivotal bio-based platform chemical, yet its direct production from inexpensive and abundant cellulose remains challenging due to the intrinsic recalcitrance of cellulose and the competing degradation of intermediates and products under acidic conditions. Herein, we report an AlCl 3 -assisted mechanochemical strategy that couples catalytic Lewis acidity with ball-milling mechanical force to activate cellulosic feedstocks, enabling their efficient one-pot conversion to HMF. Detailed structural characterizations demonstrate that the synergistic interplay between AlCl 3 and mechanical stress disrupts the extensive hydrogen-bonding network and partially cleaves β-1,4-glycosidic linkages, leading to pronounced reductions in cellulose crystallinity and degree of polymerization and, consequently, markedly enhanced chemical reactivity. The resulting mechanochemically pretreated cellulose (BMM-AlCl 3 ) was directly converted into HMF without additional catalysts during the reaction step, as the Al species introduced during pretreatment served as the catalytic sites, affording a yield of up to 46.8%. By further optimizing the Brønsted/Lewis acid balance through controlled HCl addition, the HMF yield increases to 62.8%. Importantly, this pretreatment strategy is broadly applicable to diverse lignocellulosic biomass resources, including waste paper pulp, corncob residue, bamboo powder, and corn straw, consistently delivering high HMF yields. This work establishes an efficient and potentially scalable mechanochemical route for the valorization of cellulose and lignocellulosic biomass into HMF.

Temporary plugging and diverting fracturing is an effective strategy to enhance fracture network complexity and expand the stimulated reservoir volume. However, in ultra-deep reservoirs, temporary plugging agents face a critical contradiction between maintaining high pressure-bearing capacity and achieving rapid deplugging under ultra-high temperatures, as dense structure is usually accompanied by slower degradation rate. And also, after deplugging, fractures tend to close under ultra-high in-situ stress, significantly reducing conductivity. Inspired by the stage-specific functionality and core utilization strategy of chia seeds, this study proposes an innovative, resource-efficient “soft shell–rigid core” plugging structure. A dense yet rapidly self-degradable soft shell, formed from high-temperature-resistant polymers and degradable crosslinkers, is employed to encapsulate a high-strength core to form a core–shell structure. This design balances high pressure resistance with rapid degradation, while providing sustained fracture support post-deplugging. The prepared Gel@CP undergoes a sequential process of “injection-plugging-degradation-fracture support.” It exhibits excellent fluid compatibility and suspension stability in the carrier fluid (static >3 h). Under 200 °C and 170,000 ppm salinity, the material reaches a maximum plugging pressure of 21.5 MPa, maintains 20 MPa for over 240 min, and shows a degradation rate above 99.9 % within 12 h, converting into environmentally benign water-soluble polymer fragments. After degradation, the exposed CP core effectively supports fractures, maintaining conductivity above 876 mD·cm under 70 MPa closure stress. This delicate biomimetic core–shell design endows this material with superior performance simultaneously in pressure bearing, fast degradation, and post-deplugging fracture support, which is reported for the first time, providing an innovative, sustainable, and practical solution for temporary plugging and propping under extreme reservoir conditions.

Effectively separates biomass oxidation from parasitic OER using cuprous-integrated spinel heterostructures. • Suppresses OER by thermodynamically elevating the energy barrier for *OH deprotonation. • Unlocks a record-broad anodic potential window for stable high-voltage electrosynthesis. • Sustains ampere-scale currents (>4 A) with near-unity FDCA selectivity (>90%). • Demonstrates exceptional stability up to 2200 mV in a high-flux flow electrolyzer. The industrial viability of electrochemical biomass valorization is fundamentally throttled by the parasitic oxygen evolution reaction (OER), which severely confines the stable operational window. Here, we report a strategy for expanding the operational horizon of ampere-scale biomass electrorefining using a cuprous-integrated NiCo-spinel heterostructure (Ni 1.5 Co 1.5 O 4 -Cu 2 O) that effectively decouples these competing pathways. By engineering a cuprous-integrated heterostructure, we establish a functional dichotomy wherein synergistic Ni/Co sites activate 5-hydroxymethylfurfural, while the Cu 2 O moiety selectively suppresses OER by thermodynamically elevating the *OH deprotonation barrier. This design unlocks a record-broad anodic window and, when integrated into a flow cell, delivers an exceptional 2,5-furandicarboxylic acid yield (> 90%) at industrial-scale currents (> 4 A) across an extended voltage range (up to 2200 mV). In situ spectroscopy and density functional theory calculations validate this mechanism, confirming that optimized interfacial coupling drives the selective 5-hydroxymethyl-2-furancarboxylic acid pathway. This work provides a generalizable electronic-structure engineering strategy for high-performance, scalable organic electrosynthesis.

AN-DVB-AO amidoxime resin, widely used for industrial Ga recovery in China, was synthesized. • AN-DVB-AO resin was employed for Ga adsorption from bauxite Bayer liquor in Southwest China. • The failure mechanism of the AN-DVB-AO amidoxime resin in bauxite Bayer liquor was elucidated. In recent years, the rapid development of high-tech industries including semiconductors and new energy has boosted the demand for gallium (Ga), a critical strategic metal. Bayer liquor derived from bauxite processing is the major primary source of Ga. Given increasing resource scarcity and environmental restrictions, developing efficient and eco-friendly Ga recovery technologies has attracted extensive interest. In this study, an acrylonitrile–divinylbenzene (AN–DVB) resin was synthesized via suspension polymerization and further amidoxime (AO)-functionalized with hydroxylamine hydrochloride to obtain AN–DVB–AO resin. Adsorption–desorption behavior and deactivation mechanism of the resin were systematically investigated in real bauxite Bayer liquor. Results demonstrated that the AN–DVB–AO resin exhibited high selectivity for Ga. The maximum adsorption capacity reached 13.1 mg/g after 12 h of amidoximation. After 14 reuse cycles, the Ga adsorption capacity decreased to 6.22 mg/g, representing 52.6% reduction. The primary reason for resin deactivation was the formation of a dense aluminum hydroxide (Al(OH) 3 ) layer after multiple cycles, which blocked active sites and degraded selective Ga adsorption. The aluminum (Al) content on the resin surface increased by 42.7% after 14 cycles, confirming that Al precipitation was the dominant cause of deactivation. The adsorption mechanism was clarified, providing a theoretical basis and technical support for practical Ga recovery from Bayer liquor using AO-modified resin.
