Coordination-induced reconstruction enables high-flux PU NF membranes. • Zr 4+ selectively disrupts hydrogen-bonding networks in PU layer. • Spatial reconstruction creates free volume while preserving selectivity. • 21% higher permeance with >95% rejection under acidic conditions. • Decouples permeability–stability trade-off via simple post-modification. Polyurea membranes exhibit exceptional acid-base tolerance due to their densely cross-linked structure and extensive hydrogen-bonding network, making them attractive for separations under extreme pH conditions. However, the tightly associated network also leads to limited free volume, resulting in low water permeability that hinders practical applications. Herein, we report a permeance-enhanced polyurea nanofiltration membrane fabricated via coordination-induced structural reconstruction. By introducing Zr 4+ into the polyurea network, coordination interactions with urea groups partially disrupt interchain hydrogen bonding, leading to network loosening and additional free volume. As a result, the water permeance is increased by 21% without compromising selectivity. Meanwhile, incorporation of Zr 4+ enhances membrane hydrophilicity and surface positive charge, which therefore improves antifouling properties and promotes the rejection of heavy metal ions. Importantly, the reconstructed membrane retains excellent acid resistance, maintaining a stable salt rejection above 95% over 720 h. This work provides a simple yet effective strategy to overcome the permeability-stability trade-off in polyurea membranes and offers new insights into coordination-mediated regulation of polymer network structures for high-performance separations under harsh conditions.

Microgels exhibit excellent toughening capabilities for the construction of strong and resilient hydrogels; however, their fabrication often involves complex procedures, sophisticated architectures, or biocompatibility-compromising metal catalysts. To address these limitations, we develop a metal-free orthogonal photochemical strategy that employs organic riboflavin to prepare porous double-network microgels for the fabrication of tough and printable hydrogels. This metal-free system demonstrates photochemical performance comparable to that of conventional ruthenium-based catalysts. Under light irradiation, riboflavin rapidly and orthogonally triggers free-radical polymerization of vinyl monomers and covalent crosslinking via phenolic coupling, while simultaneously enabling controlled Ca 2+ release for ionic crosslinking (within several tens of seconds). The resulting microgels possess a synergistic architecture comprising a double-network structure, which imparts exceptional energy dissipation, and an internal porous structure that enhances entanglements. When incorporated as reinforcing fillers into the hydrogel matrix, these microgels endow the bulk hydrogels with superior mechanical performance, achieving a fracture energy of ∼500 J m –2 and a toughness of ∼380 kJ m –3 . Furthermore, they confer pronounced shear-thinning characteristics and rapid self-recovery to the precursor inks. As a result, high-fidelity 3D printing of intricate architectures with feature sizes down to ∼100 μm is readily achieved, as demonstrated by a customizable pressure sensor array capable of discriminating both applied loads and object shapes. This work offers a biocompatible, efficient, and versatile strategy for preparing advanced microgel tougheners and bulk hydrogels, paving the way toward printable, tough hydrogels for a broad range of applications.

In-situ photo-patterning of ZnO was successfully achieved at room temperature. • QLEDs utilizing photolithographic ZnO as the ETL demonstrated superior performance. • The positive-aging effect was significantly alleviated by using photolithographic ZnO. • ZnO patterns were utilized to construct carrier transport channels in pixelated QLEDs. Benefiting from the adjustable emission spectrum, high color purity, wide gamut, and solution-processability, quantum dot light-emitting diode (QLED) is considered one of the most promising next-generation display technologies. As a prevalent electron transport material, ZnO plays a crucial role in enhancing the efficiency and long-term stability of QLED devices. To promote the development of high-resolution QLED displays, this study proposes a dual-functional surface engineering strategy for achieving in-situ photo-patternable ZnO with enhanced electrical properties. Physicochemical characterization revealed that surface defects of ZnO were significantly reduced via direct photolithography, thereby decreasing non-radiative exciton recombination at the QD/ZnO interface. Particularly, the red QLED devices based on photolithographic ZnO exhibited remarkable performance, achieving a peak external quantum efficiency (EQE) of 23.5%, a brightness of over 140,000 cd m −2 at 5 V, and an alleviated positive-aging effect (i.e., anomalous brightness increase). Concurrently, the operational lifetime T 95 (the time for the device luminance to drop to 95%) was also improved from 1,036 h to 2,084 h. Furthermore, by modulating the morphology of ZnO films, we successfully fabricated pixelated QLED devices, laying the technical foundation for commercializing high-resolution QLED displays.

Polylactic acid (PLA) is attractive for fused deposition modeling (FDM), yet its structural use is constrained by the coupled challenges of flammability, additive-induced embrittlement, and printed-part reliability. Herein, a material–structure integrated strategy is proposed by coupling a biomass-derived phosphorus–carbon flame-retardant formulation with multi-material FDM and beetle elytra-inspired cellular design. Epoxidized soybean oil-modified orange peel powder (EOP) was combined with ammonium polyphosphate (APP) to construct a synergistic flame-retardant PLA system, in which the optimized A20E10 formulation containing 20 wt% APP and 10 wt% EOP achieved an LOI of 34%, a UL-94 V-0 rating, and a reduced THR of approximately 30 MJ m −2 through APP-catalyzed carbonization and EOP-assisted compact char formation. To decouple fire protection from load-bearing function, A20E10 was extruded into flame-retardant PLA (fr-PLA) filament and spatially printed with neat PLA into a beetle elytra-inspired fr-PLA/PLA/fr-PLA sandwich honeycomb architecture. The resulting biomimetic structure spatially positions flame-retardant fr-PLA in the outer protective regions while retaining neat PLA as the mechanically supportive core, with the honeycomb geometry contributing to heat-transfer regulation and load dispersion. In this manner, the intrinsic flame-retardant function of A20E10 is deployed at the structural level without uniformly incorporating flame-retardant additives throughout the entire component. This work establishes a sustainable additive-manufacturing route for lightweight fire-safe PLA components with spatially programmed material functions.

The separation of ethanol from dilute aqueous solutions, such as fermentation broths, is critically important for biofuel production. Membrane distillation (MD) with porous membranes usually suffers from insufficient selectivity, while pervaporation (PV) with dense films is inadequate in permeability. To overcome this trade-off, we developed a novel hydrophobic membrane via the selective swelling of a polystyrene- b -polydimethylsiloxane- b -polystyrene triblock copolymer (SDS). By precisely controlling the swelling agent and duration, we engineered the optimal membrane with a tailored pore structure featuring interconnected nanopores and partially blind pores, along with a PDMS-enriched pore surface. This unique architecture enables a multipath permeation mechanism combing solution-diffusion and the transport pathway for molecules under vapor–liquid equilibrium within pore channels. The optimized membrane demonstrated an exceptional combination of high permeation flux and separation factor for a 5 wt% ethanol/water mixture at 50 °C, yielding a remarkable pervaporation separation index (PSI) of 38.2 kg·m −2 ·h −1 . This performance surpasses many PDMS-based PV and conventional MD membranes. This work presents a simple and efficient strategy for fabricating high-performance membranes that simultaneously achieve high flux and selectivity, offering significant potential for advancing energy-efficient bioethanol recovery processes.

Silicone rubber exhibits inherent hydrophobicity and poor lubrication performance in aqueous environments, limiting its application in medical devices. To address this challenge, we developed a thermosetting lubricating coating by incorporating polyvinylpyrrolidone (PVP) into a polyurethane-based binder system enhanced with silane coupling agent (APTES) to improve adhesion. The coating was applied to silicone rubber substrates pretreated with heptane to ensure uniform and firm attachment. Its performance was evaluated through comprehensive characterization including FTIR, SEM, EDS, contact angle measurements, tribological tests, and antibacterial assays. Results demonstrated that a PVP concentration of 3% yielded optimal wettability, reducing the water contact angle from 102.6° to 57.3° and achieving a low friction coefficient of 0.17, outperforming commercial lubricating coatings. Furthermore, iodine loading significantly enhanced short-term antibacterial efficacy, with bactericidal rates reaching 96.7% against Escherichia coli and 97.8% against Staphylococcus aureus . Although iodine release limits long-term antibacterial performance, the PVP matrix itself exhibits durable intrinsic antibacterial activity. This study presents a dual-functional coating that combines excellent lubrication and antibacterial properties, offering a promising solution for surface modification of silicone rubber-based medical devices.

PLA-based composite aerogels with high oil selectivity, good reusability, and gravity-driven transport capability are promising materials for oily-water treatment and spill remediation. However, many high-performance oil/water separation aerogels still rely on non-degradable matrices or fluorinated surface modifiers. Herein, ZIF-71 nanoparticles were incorporated into a polylactic acid (PLA) aerogel to construct a hydrophobic capillary-gating network through solution blending, water-assisted thermally induced phase separation, liquid-nitrogen freezing, and freeze-drying. The chlorinated imidazolate framework contributed hydrophobic/oleophilic domains, polyhedral roughness, and textural porosity, while the PLA matrix provided a lightweight biodegradable skeleton. Compared with pristine PLA, the optimized PZ71–3 aerogel increased the water contact angle from 114° to 136°, tensile strength from 0.088 to 0.166 MPa, elongation at break from 10% to 25%, and total pore volume from 0.0066 to 0.0091 cm³ g⁻¹ , while showing a BJH average pore diameter of 10.8 nm. The aerogel resisted a water head of 14.5 cm, selectively captured both floating heptane and sinking CCl₄, achieved oil recovery efficiencies of 98.2–99.2% with gravity-driven oil fluxes of 5300–17,200 L m⁻² h⁻¹ , and retained stable oil sorption capacity and flux over 20 cycles. Comparative benchmarking shows that PZ71–3 offers a balanced performance profile among MOF/polymer and biodegradable-polymer aerogels. This work demonstrates ZIF-71-induced hydrophobic capillary gating as an effective fluorine-free strategy for recyclable PLA-based sorbents for oil/water separation.

With the acceleration of industrialization, oily wastewater poses a serious threat to the ecological environment. Membrane separation technology has emerged as a research hotspot due to its advantages of high efficiency and energy savings; however, membrane fouling significantly restricts its long term stable operation. This study introduces a 3D COFs/MXene composite membrane with photocatalytic self–cleaning capability for highly efficient oil–water separation. A well dispersed 3D COFs colloidal dispersion was prepared via oil–oil–water three phase interfacial polymerization, effectively overcoming the dispersion challenges of COFs materials. Ti 3 C 2 T x MXene nanosheets were synthesized using the LiF/HCl etching method. Using intermolecular hydrogen bonding, the two components were ultrasonically assembled, and a COFs/MXene composite membrane was fabricated via vacuum assisted filtration. The membrane exhibits excellent hydrophilicity (water contact angle as low as 54.3°) and underwater oleophobicity (underwater oil contact angle up to 144.9°). Under visible light irradiation, the MXene component generates reactive oxygen species (·O 2 − and ·OH), enabling photocatalytic degradation of oil contaminants adsorbed on the membrane surface and thereby imparting self–cleaning functionality. Separation performance tests reveal that the composite membrane achieves efficient separation of various oil–in–water emulsions, with a maximum water flux of 1918.9 L m −2 h −1 bar −1 . The flux for n –hexane emulsion increased to 2.1 times that of pure MXene membrane, while maintaining a rejection rate above 98.8%. Moreover, the membrane demonstrates excellent cycling stability and photocatalytic antifouling performance. This research offers a novel strategy for developing self–cleaning separation membranes and holds promising potential for application in oily wastewater treatment.

A strategy for plasma-coupled O v -rich catalytic hydrogen production is proposed. • The catalyst shows high activity and universality for hydrogen production. • Synergistic cascade from plasma dissociation to catalytic surface reforming. • The key mechanism of “hydrogen promotion and anti-coking” were revealed. Hydrogen production from plastics contributes to the circular economy by enabling both waste valorisation and green energy generation. Integrated pyrolysis-plasma catalytic technology offers notable advantages in improving hydrogen production, but it still faces challenges such as catalyst coking and limited understanding of the reaction mechanisms. This study proposes a water vapor plasma-coupled oxygen vacancy-rich (O v -rich) catalytic strategy to systematically investigate the improved hydrogen production from plastics over an anti-coking catalyst. The results show that the O v -rich catalyst exhibits outstanding hydrogen production activity, strong synergistic effect, and universality in the non-thermal plasma catalytic (NTP-C) reforming reaction of mixed model compounds in plastic pyrolysis oil. Crucially, its practical effectiveness was successfully validated in the NTP-C reforming of polyethylene (PE)/polypropylene (PP) pyrolysis oils. Moreover, the O v -rich catalysts significantly inhibited coking and maintained good stability for 1800 min in a multi-component mixed system. The mechanisms of hydrogen production and coking inhibition were revealed via Density Functional Theory (DFT) calculations, in situ plasma-coupled Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS), and Optical Emission Spectroscopy (OES). A synergistic reaction pathway, coupling plasma gas-phase dissociation with catalytic surface reforming, was identified as a key mechanism for enhancing hydrogen yield in plasma-catalytic systems. The study offers valuable insights for advancing plasma-assisted hydrogen production technologies. Download: Download high-res image (150KB) Download: Download full-size image

Efficient encapsulating of highly hydrophilic low-molecular-weight compound within poly (D, L-lactic-co-glycolic acid) (PLGA) to obtain microspheres with both excellent drug loading capacity (DL) and encapsulation efficiency (EE) was substantially challenging. This study specifically aimed to enhance both the DL and EE of this hydrophilic low-molecular-weight compound S-propargyl-cysteine (SPRC) while extending its release duration through implementation of the solvent-induced phase separation (SIPS) methodology. S-propargyl-cysteine (SPRC)-loaded PLGA microspheres (SP-MSs) were fabricated using conventional emulsion solvent evaporation techniques (W/O/W and S/O/W) and compared with those prepared via SIPS. The influences of various preparation techniques on critical pharmaceutical properties of sustained-release SP-MSs, including drug loading capacity, encapsulation efficiency, in vitro release profiles, surface-localized drug content, crystal state of SPRC, and microstructural characteristics were also systematically investigated. Microspheres sythesized through SIPS demonstrated a remarkable enhancement in DL, increasing from 0.90% to 9.91%, with the corresponding EE improving dramatically from 17.8% to 99.2%. Furthermore, the SIPS approach effectively mitigated the initial burst release phenomenon commonly observed in polymeric microsphere formulations. In vivo pharmacokinetic studies in Sprague-Dawley rats confirmed the sustained-release profile of the optimized formulation, maintaining stable plasma concentrations for an extended period of seven days. These findings establish SIPS as a superior methodology for encapsulating SPRC within PLGA microspheres, effectively addressing dual challenges of low DL and EE. This investigation provides significant methodological insights for the effective encapsulation of hydrophilic low-molecular-weight therapeutic agents within PLGA-based delivery systems, offering a promising strategy for achieving prolonged sustained-release both in vitro and in vivo . Solvent-induced phase separation was employed to encapsulate highly hydrophilic S-propargyl-cysteine (SPRC) within injectable PLGA microspheres to (i) maximize EE and DL, (ii) suppress the initial burst, and (iii) achieve prolonged, controlled release of SPRC for 7 days both in vitro and in vivo .

Fat content shapes rice eating and nutritional quality, yet its climate response remains unclear. In this study, we combined six years of multisite field observations across nine provinces in southern China with an interpretable random forest model to identify drivers of rice fat. The model showed that the minimum nighttime temperature during grain filling (TMIN) was identified as the primary factor. Fat content increased with TMIN, whereas the unsaturated fatty acid index (IUFA) exhibited three distinct accumulation patterns and generally declined at higher TMIN. This pattern indicates a physiological tradeoff potentially linked to changes in energy metabolism and membrane stability of rice. Patterns were independently validated in 2024 field trials at 11 sites. Furthermore, projections indicate higher fat under warming but declining IUFA, especially in early- and mid-season rice. These results support climate-resilient cultivation, sustainability, and quality management of rice.

For complex oily wastewater, establishing multi-scale in-situ anti-fouling separation membrane materials can effectively mitigate membrane fouling and achieve wastewater purification. Based on this, this study prepared a multifunctional membrane material (PC/Co 3 S 4 @NW) that combines super-wetting properties with catalytic functionality. The membrane's superwetting property originates from hydrogel encapsulation, with salt precipitation enhancing the hydrogel's stability. The PC/Co 3 S 4 @NW is exceptional in superhydrophilicity and underwater oleophobicity, enabling efficient separation of oil-water mixtures (separation efficiency >97%) and oil-water emulsions (separation efficiency >95%). The catalyst loading imparts to the PC/Co 3 S 4 @NW membrane the ability to catalyze the degradation of aqueous organic pollutants, achieving removal rates exceeding 99.5% for various dyes. This degradation effectively mitigates the decline in separation flux caused by membrane fouling. Furthermore, during a continuous filtration process lasting 10 h, the PC/Co 3 S 4 @NW membrane consistently maintained a dye removal rate of over 93%. Radical scavenging tests and degradation kinetic testing elucidate the membrane's catalytic mechanism. What's more, the PC/Co 3 S 4 @NW membrane can achieve significant purification efficacy for complex actual oily wastewater. This in-situ separation-catalysis strategy offers a viable pathway for purifying complex oily wastewater and efficiently mitigating membrane fouling.
