Fully aromatic fluorinated polyamide nanofiltration membranes are manifesting the great potential in organic solvent nanofiltration (OSN) especially for their excellent structural stability when exposed to solvents and enhanced nonpolar organic solvent permeance compared with the conventional polyamide membranes. However, the fluorinated amino monomers are difficult to be dissolved in water that impedes the large-scale manufacture of fluorinated polyamide selective layers via the typical interfacial polymerization at the water-alkane interfaces. Herein, we report a straightforward and effective strategy for fabricating aromatic fluorinated polyamide nanofiltration membranes at gas/liquid interfaces while hydrophobic 2,2-bis(4-aminophenyl)hexafluoropropane gases and trimesoyl chloride solutions are selected as the gas and liquid phases, respectively. The obtained membranes show outstanding hydrophobicity with water contact angles of 92°, which is beneficial for the nonpolar organic solvent permeance. The molecular dynamics simulations could also prove that the fluorine-containing groups exhibit much lower absolute interaction energies with the nonpolar solvents compared with those of polar ones. Therefore, our membranes demonstrate an extremely high n-hexane permeance of 21.52 L m −2 h −1 ·bar −1 while maintaining a low MWCO of approximately 452 Da. Moreover, the high fluorine contents endow the membranes with good stability resulting in almost unchanged rejection and permeance during long-term operation.

To address the sluggish dehydrogenation kinetics and high operating temperatures of LiBH 4 , Ti 2 VC 2 MXene was incorporated with LiBH 4 to modify its dehydrogenation performance. With 40 wt% Ti 2 VC 2 MXene additive, the onset dehydrogenation temperature of LiBH 4 is reduced to 98.31 °C, while the peak hydrogen release occurs at 332.86 °C. Isothermal dehydrogenation measurements demonstrate that the composite rapidly desorbs 9.50 wt% H 2 within 40 min at 325 °C, 10.67 times faster than that of LiBH 4 . Furthermore, the addition of 40 wt% Ti 2 VC 2 MXene effectively lowers the activation energies for the dehydrogenation to 104.76 and 112.99 kJ mol⁻ 1 , respectively. Mechanism studies reveal that the enhanced dehydrogenation performance originates from the in-situ formation of catalytic active species, including Ti 0 , V 0 and Li 3 BO 3 , promoting the cleavage of ionic and covalent bonds in LiBH 4 . Simultaneously, the multiphase Ti/V/Li 3 BO 3 hetero-ensembles create abundant interfacial boundaries, serving as efficient pathways for hydrogen diffusion and accelerating the dehydrogenation kinetics.

The commercialization of cesium lead halide perovskite quantum dots (QDs) is hindered by lead toxicity and poor stability. We propose a synergistic “chemical-physical” dual-confinement strategy. Chemically, Sn 2 + and Cu 2+ are co-doped into CsPbBr 3 , forming low-lead CsSn 0.7 Cu 0.1 Pb 0.2 Br 3 QDs, where Sn 2+ tunes the bandgap and Cu 2+ passivates Sn-related defects. Physically, QDs are in-situ grown within halloysite nanotubes (HNTs), a natural clay, serving as a nanoreactor and barrier. Silane modification enhances hydrophobicity. The composite exhibits high photoluminescence quantum yield (73.46%), excellent thermal reversibility, and remarkable water resistance (86% intensity retention after 12 h). Applications include a wide-color-gamut white light-emitting diode (122.1% of National Television System Committee (NTSC)) and an efficient visible-light photocatalyst for methylene blue degradation. This work provides a sustainable pathway for stable, low-toxicity perovskite materials in optoelectronics and environmental remediation.

Chalcopyrite and galena exhibit excellent natural floatability, posing significant challenges in their separation through flotation processes. Application and interaction mechanism of Fe 2+ in enhancing flotation separation between chalcopyrite and galena was investigated by flotation experiments, wettability analysis, adsorption capacity tests, zeta potential analysis and X-ray photoelectron spectroscopy. This study indicated that Fe 2+ significantly enhanced flotation separation between galena and chalcopyrite. Contact angles of chalcopyrite decreased, while that of galena increased after reaction with Fe 2+ . The addition of Fe 2+ improved the adsorption of the ethyl thiocarbamate on the surface of galena and dramatically reduced that on the surface of chalcopyrite. The zeta potential of the galena and chalcopyrite shifted positively when Fe 2+ was present, and the zeta potential shift of galena was greater than that of chalcopyrite. The presence of Fe 2+ led to an increase in the concentration of total S, S 2− and S n 2- on the surface of galena, and promoted the formation of a ferric hydroxide coating on the surface of chalcopyrite. Thus, the introduction of Fe 2+ effectively enhanced the flotation separation between galena and chalcopyrite.

Co 3 O 4 is a promising catalyst for propane combustion but is limited by poor water resistance and insufficient high-temperature stability. Noble metal loading is widely employed to enhance its performance, however, the metal-specific effects remain poorly understood. In this work, Co 3 O 4 -supported Pt, Pd, and Ru catalysts were systematically investigated for propane oxidation. It was found that all noble metals decreased the surface Co 2+ content and oxygen vacancies, leading to modified redox behavior and propane activation ability. Among them, Ru incorporation enhanced the catalytic activity (T 90 = 266 °C) of Co 3 O 4 (T 90 = 286 °C) and significantly improved its water resistance and thermal stability. These improvements are mainly attributed to the abundant partially oxidized RuO x species, which provide additional active sites and facilitate propane adsorption and activation. In contrast, Pt and Pd modification inhibited propane oxidation due to the intrinsically low activity of highly oxidized Pt species and PdO, as well as the coverage of Co 3 O 4 active sites caused by highly dispersed Pt and particulate PdO. The findings offer mechanistic insights for the rational design of efficient catalysts for propane combustion and VOCs abatement.

Rare-earth-doped upconversion materials play a crucial role in the development of temperature sensing based on fluorescence intensity ratio (FIR). In this work, the upconversion (UC) luminescence of GdAlO 3 (GAP):Yb 3+ ,RE 3+ (RE = Ho, Er, Tm) phosphors was investigated. Under 980 nm laser excitation, GAP:Yb 3+ ,Ho 3+ emitted green ( 5 F 4 , 5 S 2 → 5 I 8 ) and red ( 5 F 5 → 5 I 8 , 5 F 4 → 5 I 7 ) light, GAP:Yb 3+ ,Er 3+ emitted green ( 2 H 11/2 , 4 S 3/2 → 4 I 15/2 ) and red ( 4 F 9/2 → 4 I 15/2 ) light, GAP:Yb 3+ ,Tm 3+ emitted blue ( 1 G 4 → 3 H 6 ) and red ( 1 G 4 → 3 F 4 , 3 F 3 → 3 H 6 ) light. Within the temperature range of 260–500 K, GAP:Yb 3+ ,Ho 3+ exhibits a maximum absolute sensitivity ( S a ) of 0.0078 K −1 at 460 K and a maximum relative sensitivity ( S r ) of 1.391% K −1 at 300 K, corresponding to the non-thermally coupled levels (NTCLs) 5 S 2 / 5 F 5 . Meanwhile, GAP: Yb 3+ ,Er 3+ shows a maximum S a of 0.00367 K −1 at 500 K and a maximum S r of 1.562% K −1 at 260 K, associated with the thermally coupled levels (TCLs) 2 H 11/2 / 4 S 3/2 . Remarkably, the maximum S a and S r of GAP:Yb 3+ ,Tm 3+ reached 0.03576 K −1 at 500 K and 6.740% K −1 at 260 K for NTCLs 1 G 4 / 3 F 3 .

High concentration of surfactant, lipid, metal salts, tanning agent, dye and other leather auxiliaries contain in wet-blue, crust leather and tannery wastewater. The existence of these complicated matrices seriously affects the performance of analytical instruments and the accuracy of conventional analytical methods. In this study, to effectively avoid matrix interference of leather and tannery wastewater by simple pretreatment process, thermo-magnetic dual-template molecularly imprinted polymers (TM-dt-MIPs) were prepared and used as magnetic solid-phase extraction (MSPE) adsorbent to simultaneously selective extract ten kinds of phenols (phenol, five chlorophenols (CPs), and four alkylphenols (APs)), coupled with HPLC analysis. The TM-dt-MIPs prepared by stimuli-responsive imprinting and multi-template imprinting techniques utilized magnetic graphene oxide-multiwalled carbon nanotubes as supporting material, N-isopropyl acrylamide and methacrylamide as functional monomers, 2,4-dichlorophenol and nonylphenol as dual template, showing uniform morphology, high magnetic property and thermal stability. Crucially, the thermo-sensitivity and adsorption ability for target phenols were assessed through thermo-regulated capture/release, static, dynamic and selective adsorption studies, confirmed that the adsorption and desorption of the target analytes could be effectively controlled by external temperature regulation and magnetic manipulation. The developed TM-dt-MIPs-MSPE-HPLC method exhibited excellent analytical performance, characterized by high enrichment factors (26.63–110.4), wide linear ranges (2–200 μg L −1 ), low limits of detection (0.10–0.36 μg L −1 ), limits of quantitation (0.34–1.21 μg L −1 ) and good precision (intra-day RSD: 1.61–6.84%; inter-day RSD: 2.15–8.51%). For the analysis of ten phenols in crust leather, wet blue, and tannery wastewater samples, satisfactory recoveries were achieved ranging from 72.27 to 119.6%, demonstrating the practical application prospects for trace phenol analysis in leather industrial matrices.

Polyvinylidene fluoride (PVDF) and its copolymer-based piezoelectric composites are widely used in piezoelectric sensors to facilitate efficient energy conversion due to their flexibility and high electromechanical coupling properties. In this study, we introduce a piezoelectric nanogenerator (PENG) that utilizes BaTiO 3 –Nb 2 O 5 @PDA@MWCNTs/P(VDF-TrFE) composite films (BNP-MCP) for detecting environmental mechanical stimuli and enabling wireless monitoring. Notably, adding 5 wt% BaTiO 3 –Nb 2 O 5 @PDA@MWCNTs increases the dielectric constant (εᵣ)of BNP-MCP to 21.8 from the 14.8 of pristine P(VDF-TrFE) at 100 Hz, thereby enhancing the PENG's output performance by improving the charge density. By optimizing the BaTiO 3 –Nb 2 O 5 @PDA content in the P(VDF-TrFE) matrix, the fabricated PENG is characterized by an output voltage of 7.5 V and a maximum power density of 4.52 μW cm −2 . This optimized PENG maintains stable performance after 4500 bending-releasing cycles and exhibits high sensitivity in detecting diverse mechanical stimuli, spanning from subtle perturbations (e.g., leaf fall and insect crawling) to intense impacts (e.g., water flow and human jumping). Additionally, an autonomous all-weather rainfall monitoring system leverages wirelessly received piezoelectric signals to trigger real-time precipitation alerts with three-tier warning thresholds: light rain, moderate rain, and heavy rain. This study establishes a sustainable monitoring framework for agricultural and environmental applications, advancing next-generation self-powered sensing technologies.

The extensive utilization of superhydrophobic wood is currently impeded by the poor durability of coatings and the reliance on toxic low-surface-energy chemicals. Herein, a fluorine-free superhydrophobic coating was developed, and consequently, a superhydrophobic wood with comprehensive robustness was fabricated based on this formulation. Specifically, the essential surface roughness was created using SiO 2 particles. Cellulose nanofibrils (CNFs) were incorporated simultaneously as a dispersant and a reinforcing phase, suppressing particle agglomeration and enhanced the durability of the superhydrophobic wood. Furthermore, low-surface-energy modification utilizing hexadecyltrimethoxysilane (HDTMS) and polydimethylsiloxane (PDMS) were implemented to achieve hydrophobic grafting at the molecular level and cross-linked encapsulation at the macroscopic scale. Through the synergistic design that integrates mechanical reinforcement of CNFs, chemical inertness with minimized surface energy of HDTMS/PDMS, and hierarchical surface architectures of SiO 2 , the superhydrophobic performance of wood was systematically optimized across the physical, chemical, and structural dimensions. Specifically, the surface exhibited superhydrophobicity with a static contact angle of 157.6° and a sliding angle of 6.3°. The material also demonstrated excellent durability, maintaining its superhydrophobicity after prolonged exposure to harsh conditions, including saltwater immersion (96 h), chemical corrosion (pH = 2–12), sandpaper abrasion (200 cm under 100 g), tape peeling (200 cycles), UV aging (216 h), and outdoor exposure (25 days). This durability arises from the synergy between its chemically stable components and reinforced micro-nano structure, in which nano-SiO 2 particles play a key role in enhancing UV resistance by absorbing and scattering radiation to prevent polymer photo-oxidation. The coating also demonstrated broad substrate universality, performing effectively on diverse materials such as paper, cotton, glass, wood, and metals, highlighting its potential as a universal superhydrophobic solution. In summary, this work presents a scalable, eco-friendly strategy for creating durable, high-performance superhydrophobic wood, paving the way for next-generation materials.

Cadmium (Cd(II)) poses a severe threat to rice production and food safety, and exogenous organic matter (EOM) offers a cost-effective, eco-friendly solution for Cd(II) remediation. Nevertheless, the effect of EON on root electrochemistry and the relationship with Cd(II) uptake and sequestration remains elusive. This study elucidates the Cd(II) tolerance mechanisms in two rice cultivars ( Oryza sativa L., Cd(II)-tolerant WYJ24 and Cd(II)-sensitive FD88) in a hydroponic system under biochar and organic acid treatments. The results revealed that WYJ24 exhibited superior Cd(II) tolerance, maintaining higher root elongation (1.35–3.66 times > FD88) and restricting Cd(II) translocation (shoot-to-root ratio < FD88). This observation was associated with enhanced Cd(II) complexation (70.7% vs. 22.9% after 10 d) and fewer root negative charges (-10.6 vs. −13.4 mV at pH 6.73) in the roots of WYJ24 relative to FD88, respectively. Root exudate profiling under Cd(II) stress revealed WYJ24 exhibiting a targeted, transient increase in specific acids (e.g., malic, quinic), while the sensitive FD88 exhibited a significant, dysregulated exudation. Also, biochar-supplemented media significantly increased root negative zeta potential and functional group concentration, which significantly correlated with total absorbed and exchangeable Cd(II). However, organic acids exhibited cultivar-specific responses, with oxalic acid modulating Cd(II) adsorption in FD88 via protonation while enhancing complexation in WYJ24. Therefore, the findings reveal that Cd(II) tolerance is governed by a combination of root surface properties and internal sequestration efficiency, and that organic amendments function by selectively modifying the root interface. However, the translation of these hydroponic insights into field applications requires future validation under realistic soil conditions.

This study investigated the synergistic effect of fat and sarcoplasmic protein on the flavor profile of chicken white soup. The impact of adding 2% fat (2%O), 0.56% sarcoplasmic protein (0.56%P), and their combination (2%O-0.56%P) on volatile compounds, taste components, and sensory characteristics was evaluated. Through odor activity value (OAV) and gas chromatography-olfactometry (GC-O) analysis, hexanal, heptanal, octanal, nonanal, (E,E)-2,4-decadienal, (E)-2-octen-1-al, and 1-octen-3-ol were identified as key aroma contributors. The combination of 2%O and 0.56%P markedly enhanced the aroma profile of the chicken soup, concurrently achieving the highest levels of amino acids and 5′-nucleotides. Furthermore, electronic tongue analysis revealed that the chicken soup supplemented with 2%O-0.56%P exhibited the lowest bitterness value and achieved the highest overall acceptability. These findings demonstrate that the synergistic effect of fat and sarcoplasmic protein effectively improves the flavor quality of chicken white soup, providing a theoretical basis for developing flavorful, tasty, and consumer-preferred chicken soup products.

Resin impregnation is an important wood modification technique. However, conventional thermosetting resins are inherently insoluble and infusible, posing significant challenges to their recycling and reuse-a fundamental contradiction with wood's eco-friendly and renewable nature. This study introduced Schiff base and boronate ester bonds into a water-based epoxy (EP) resin system. The reversible cleavage and rearrangement of these dynamic bonds endowed the EP resin with plasticity, enabling reprocessing and reforming, while enhancing its toughness to overcome the high brittleness of common epoxy resins. The resin formed a stable network within the wood, reducing leaching and improving wood water resistance and dimensional stability. Additionally, silicon in Schiff base moieties and boron in boronate ester groups conferred good flame retardancy to the water-based epoxy resin. For the modified wood: limiting oxygen index (LOI) increased by 28.3%; vertical burning rating reached V-0; infrared thermal imaging central temperature decreased by 61.2%; thickness swelling rate reduced to 2.3%; and elastic modulus significantly increased by 73.33%. Life cycle assessment showed that compared with the PMMA impregnation process, the epoxy resin impregnation process reduced global warming and marine eutrophication impacts by 21.7% and 87.6%, respectively. Accelerated aging tests confirmed that dynamic bonds did not undergo irreversible fracture, and the mechanical properties and water resistance of modified epoxy resin and resin-impregnated wood remained stable. This research provides a novel strategy for strengthening, toughening, flame-retarding, and enabling recyclability of fast-growing wood via dual dynamic bonds in water-based epoxy resin. It addresses thermosetting resin recycling, allows wood reprocessing, extends service life, and expands the application fields of wood-based materials.
