Most studies only preliminarily assessed the effects of non-grain supplemental levels on the physicochemical and nutritional properties of steamed bread, and few further analyzed the ways to improve its quality by changing the properties of raw materials themselves. This study investigated the effect of Monascus -fermented autoclaved whole soybean flour (FAWSF) and autoclaved whole soybean flour (AWSF) as wheat flour substitutes in making steamed bread. The contents of protein and soluble dietary fiber were higher in FAWSF than in AWSF. Steamed bread substituted with FAWSF significantly reduced the degree of crystallization and retrogradation. Furthermore, the steamed bread with 5% FAWSF was better than the control in terms of specific volume, texture, total phenolic content, and soybean isoflavones, improving the overall quality of steamed bread. Therefore, FAWSF is a promising new food ingredient.

This study developed a comprehensive strategy to identify and quantify a novel vardenafil analogue, SLX-2101, which was detected as an undeclared adulterant in functional foods. The compound was initially screened and characterized using ultra-performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC-UV-Q-TOF/MS), and its structure was confirmed via nuclear magnetic resonance (NMR) spectroscopy and comparison with a custom-synthesized reference standard. A quantitative ultra-performance liquid chromatography–tandem mass spectrometry (UHPLC-QqQ/MS) method was established and validated, demonstrating good linearity (1.0–100.0 μg/L, r > 0.997), with a limit of detection of 0.3 μg/kg and a limit of quantification of 1.0 μg/kg. Mean recoveries ranged from 74.2% to 115.8% across various food matrices, with relative standard deviations between 0.4% and 12.5%. Application to 61 commercial samples revealed SLX-2101 in two functional wines marketed for their purported aphrodisiac effects at concentrations of 19.3 mg/kg and 1.3 × 10 3 mg/kg. The validated method enables reliable surveillance of this emerging adulterant, thereby providing a practical solution to address the critical gap left by conventional targeted screening protocols.

A ternary structure (CuO/CN/LDH) composed of LDH-anchored g-C 3 N 4 nanosheets loaded with CuO nanoparticles was successfully constructed via hydrothermal and co-precipitation methods, and a colorimetric sensing platform for hexavalent chromium (Cr(VI)) detection was proposed. The engineered nanomaterial demonstrates significantly enhanced oxidase-mimetic activity in the presence of Cr(VI), enabling rapid catalytic oxidation of 3,3’,5,5’-tetramethylbenzidine (TMB) with distinct chromogenic response. Mechanistic investigations reveal that Cr(VI) facilitates the conversion of dissolved oxygen into superoxide anions via redox cycling, thereby accelerating TMB oxidation. The sensor exhibits exceptional analytical performance with high accuracy (recoveries of 97.3-103.8%) and sensitivity (detection limit of 25 nM) in aqueous sample analysis. The sensor demonstrated excellent selectivity against common interfering metal ions, as well as high stability (still above 95% for 8 weeks). Notably, an innovative paper-based analytical device was developed in conjunction with smartphone-assisted colorimetric detection, achieving on-site visual quantification of Cr(VI) within 15 min. This integrated system provides a field-deployable solution for environmental monitoring, combining operational simplicity with reliable detection capabilities. This study addresses the main limitations of Cr(VI) sensors, such as their dependence on complex instruments and poor stability of natural enzymes, and demonstrates low detection limits, excellent selectivity, and long-term stability. In addition, the proposed methodology advances current sensing technologies by merging nanomaterial engineering with portable detection platforms, demonstrating significant potential for heavy metal surveillance in water quality management. Based on this, this study also constructed a paper-based colorimetric detection sensor.

Cellulose fiber (CF) is widely used as a flexible substrate in material science and bio-medical engineering. However, a majority of traditional research focuses solely on overcoming the bottleneck of CF in mechanical properties and improving resistance characteristics attributed to self-defects, ignoring the selection of non-toxic reinforcing agent and green, efficient and scalable production demands. In this work, a clean and scalable strategy, sizing process of waterborne emulsion was proposed for reinforcing CF paper. This innovative approach focused on controlling the insertion of 2D tung oil anhydride (TOA) layer based on the thermoset of TOA in the thermal reaction to form ester bond between cellulose and TOA due to the high chemical activity of TOA. Accordingly, the extensive ester bonds between CF and TOA enhanced cross-linking density and interfacial adhesion between CF, resulting in excellent tensile strength and toughness. Particularly, TOA/CF paper showed a tensile strength of 87.62 MPa, Young's modulus of 2.98 GPa and impact strength of 31.26 kg . f/mm 2 when the added content of TOA was 7 wt%. Moreover, the TOA/CF paper exhibited better hydrophobicity (water contact angle of 117° ± 3°) and thermal stability than pure CF paper. The developed TOA/CF paper featuring green and high yield fabrication has promising applications as a flexible substrate in various industries.

Camellia oleifera is one of the important woody oil crops in China, and its food safety has attracted much attention. Mercury (Hg) is a highly toxic heavy metal ion, which can enter Camellia oleifera and its products through environmental migration and bioaccumulation, and poses a potential threat to human health. In this study, an imine-linked three-component covalent organic framework (TD-COF) was synthesized by Schiff base reaction from 4,4′,4″-(1,3,5-triazine-2,4,6-triyl) tris (TZ), 2,5-dimethoxyterephthalaldehyde (DM), and 2,5-dihydroxy-1,4-benzenedicarboxylic aldehyde (DA). TD-COF features a rapid and highly sensitive detection of Hg 2+ with a detection limit of 8.43 nM. In actual Camellia oleifera samples, it demonstrated excellent recovery (96.3%–102.54%) and stability. It shows excellent potential for designed imine-linked fluorescent COFs in Camellia oleifera detection.

Covalent organic framework (COF) nanofiltration membranes exhibit intrinsically high permeability and considerable potential for dye/salt separation in printing and dyeing wastewater treatment. However, severe membrane fouling under high-flux operation remains a major obstacle to their practical application. Herein, a defect engineering–enabled surface hydrophilization strategy is proposed to substantially enhance antifouling performance while preserving high permeation selectivity. Tunable free amino groups are incorporated into the COF framework through controlled defect engineering and subsequently serve as anchoring sites for the covalent grafting of hydroxyl-rich gluconic acid chains via EDC/NHS-mediated coupling. Precise regulation of defect content allows accurate control over the grafting density of hydrophilic chains, facilitating the formation of a stable hydration layer on the membrane surface through hydrogen-bonding interactions with water. This hydrated interface effectively suppresses foulant adhesion without sacrificing the intrinsic permeability of the COF membrane. The optimized dCOF-40-OH membrane delivers a high water permeance of 123.8 L m −2 h −1 ·bar −1 . It exhibits markedly enhanced antifouling performance against pump oil emulsions, achieving a flux recovery ratio of 96.4%, a total flux decline ratio of 11.8%, and an irreversible flux decline ratio of 8.2%. Meanwhile, the membranes exhibit excellent dye/salt separation performance for various dyeing saline solutions, among them the separation factors for Eriochrome Black T (EBT)/NaCl and EBT/Na 2 SO 4 reach up to186 and 168, respectively. This work provides a rational and effective strategy for reconciling high permeability, robust antifouling capability, and efficient dye/salt separation in COF-based nanofiltration membranes.

This study developed a dilute acid pretreatment method (0.3 M HCl) for the efficient production of nanochitin, achieving a yield of 87.14%. The obtained nanofibrils measured 271.15 ± 13.64 nm in length and 10.25 ± 0.50 nm in width, with a crystallinity of 87.15%. This strategy demonstrated a comparable hydrolysis effect to the conventional 3 M HCl method. A Pickering emulsion with smaller droplets and excellent emulsification performance was prepared by homogenizing nanochitin and gelatin at a total mass concentration of 1%. When the nanochitin-to-gelatin ratio was 5:5, the storage modulus of the emulsion was approximately 2.5 times that of the system stabilized by gelatin alone. Furthermore, increasing the mass concentration above 2% resulted in the formation of an emulsion gel, which exhibited significantly enhanced rheological performance and stability.

Marangoni-Rayleigh-Bénard (MRB) convection characteristics during mass transfer within compound droplets were studied by integrating digital particle image velocimetry for flow visualization and schlieren imaging for concentration field analysis. Through comparative analysis of MRB convections in single-phase droplets, the hydrodynamic mechanisms underlying interfacial evolutions and vortex-cellular convection patterns in compound droplets were elucidated. Furthermore, the influences of initial solute concentration ( c 0 ) and core-shell ratios ( r / R ) on MRB convection behaviors, mass transfer properties, and morphological evolution of compound droplets were revealed. Three MRB convection patterns were identified: the Marangoni effect-dominated pattern (MD-pattern) with multiple pairs of counter-rotating vortex cells, the transition pattern (T-pattern) distinguished by a couple of co-rotating vortex cells, and the Rayleigh-Bénard effect-dominated pattern (RBD-pattern) characterized by a set of counter-rotating large vortex cells. At the initial Marangoni number Ma 0 ≥ 0.669 × 10 7 ( c 0 ≥ 20 wt%), the convection transitioned from the MD-pattern to the T-pattern and finally to the RBD-pattern, whereas at Ma 0 ≤ 0.361 × 10 7 ( c 0 ≤ 10 wt%), only the RBD-pattern was observed. For Ma 0 = 0.530 × 10 7 (15 wt%), a limited Marangoni effect competes with the Rayleigh-Bénard effect, resulting in the T-pattern. The convection intensity in droplets was enhanced by increased interfacial tension gradients, thereby significantly promoting mass transfer and resulting in pronounced droplet contraction. Conversely, the core-shell structure mitigated droplet contraction by reducing solute content that shortens the mass transfer duration while imposing spatial confinement that inhibits internal convection development. Notably, the vertical contraction far exceeded horizontal contraction due to the combined effects of lateral fluid migration driven by interfacial tension gradients at the droplet bottom and gravity-induced downward flow of fluid at the upper region.

Potassium copper ferrocyanide (KCuFC) is considered promising for rubidium resource recovery with high adsorption capacity and excellent selectivity. However, its microcrystalline powder structure restricts the recycling. In this work, a useful ternary hydrogel was prepared using graphene/polyvinyl alcohol/chitosan/tetracarboxylic acid (RPCT) by via hydrogen bond reaction. In which graphene makes the improved stability, tetracarboxylic acid offers many chelating sites for Cu 2+ . Further, potassium copper (II) ferrocyanide anchoring hydrogel composites (RPCT-KCuFC) could be formed in situ in 40 mmol L −1 K 4 Fe(CN) 6 by coprecipitation. Various FE-SEM, EDS, XRD, IR, and other technologies proved the structure, composition, and physical properties. The recovery of Rb + was investigated using RPCT-KCuFC from solution in detail. The adsorption process fits pseudo-second-order model with three-stage intraparticle diffusion process, and the Langmuir isotherm model could explain the adsorption behavior. The adsorption capacity is about 262.48 mg g −1 (45°C, 4 h, pH 7, [Rb + ] initial = 10 mg L −1 ). Over 95% of Rb + could be desorbed from the RPCT-KCuFC (Rb + ) in 0.5 mol L −1 of HCl/NH 4 Cl with 4 h. Moreover, RPCT-KCuFC was applied to recover Rb + from simulative brine. The present work provided effective immobilization strategies of KCuFC for separating Rb + .

Efficient CO 2 separation is pivotal to lowering the energy consumption and costs of carbon capture, utilization, and storage (CCUS), and thin-film composite membranes (TFCMs) with high permeance have emerged as a preferred solution for carbon neutrality and global climate change mitigation. Polyethyleneimine (PEI) exhibits excellent CO 2 adsorption capability owing to its unique amino structure, however, its excessive accumulation on the substrate surface and pore penetration lead to an overly thick functional layer, which significantly impairs the gas permeability of TFCMs. This work successfully developed a novel ultrathin polyethyleneimine (PEI) composite membrane based on MOFs nanosheets gutter layer via interfacial polymerization. Benefiting from the significant improvement of the surface properties of substrate by the MOFs nanosheets gutter layer, the prepared PEI functional layer exhibited an ultrathin thickness less than 135 nm with a highly ordered structure. The CO 2 permeance reached 779.6 GPU, with excellent selectivities of 59.1 for CO 2 /N 2 and 54.1 for CO 2 /CH 4 . The resulting TFCMs demonstrated excellent CO 2 separation performance, surpassing the 2008 and 2019 upper bound while maintaining long-term separation stability. The study provided new insights into the precise design and controllable preparation of gas separation membranes, offering valuable reference for the industrial development of high-performance CO 2 separation membranes.

Tannin-boron (TB) treatment is an effective method for enhancing the biological resistance of some types of wood, although knowledge regarding its efficacy as a preservative in a wider range of wood is limited. In this study, we investigated the effects of TB treatment on the mechanical and microscopic properties, and on biological resistance of six types of wood (Pinus massonianaLamb.,Cunninghamia lanceolata(Lamb.) Hook,Pseudotsuga menziesii(Mirb.) Franco,Intsia bijuga(Colebr.) Kuntze,Tectona grandisL. f., andQuercus mongolicaFisch. ex Ledeb.). The results showed that the six types of wood exhibited different boron retention after leaching, with the highest retention rate, 21.85%, observed inP.massoniana. The TB treatment did not significantly alter the original density and compressive strength of the wood, except in the case ofI.bijuga, where the compressive strength significantly decreased after treatment. Scanning electron microscopy revealed that TB preservative is attached around the tracheids of softwood, or deposited within the vessels of hardwood. No-choice feeding tests showed that the TB-treated wood exhibited high resistance toCoptotermes formosanuswith a maximum weight loss of 2.5%. TB treatment significantly improved the resistance ofP.massoniana,C.lanceolata,P.menziesii, andT.grandistoTrametes hirsuta. These results demonstrate the potential usefulness of TB preservatives in different wood types.
