Polyethylene glycol (PEG), a versatile non-ionic surfactant with excellent biocompatibility and robust chemical stability, offers significant potential for the precise regulation of interfacial polymerization (IP). In this study, PEG was introduced into the aqueous phase as an additive to modulate the interfacial diffusion behavior of piperazine (PIP). By systematically optimizing its molecular weight, concentration, and terminal group parameters, a polyamide (PA) active layer with a smaller and more uniformly distributed pore structure was successfully constructed. This optimized architecture effectively strengthened both the size exclusion and charge repulsion mechanisms of the nanofiltration (NF) membrane. Consequently, the optimal MP 1000 -10 membrane exhibited highly competitive NF performance, achieving an impressive Na 2 SO 4 rejection of 98.0% and a high water permeance of 11.5 L m −2 h −1 bar −1 . More importantly, tailoring the PEG terminal groups facilitated targeted control over the pore size and surface charge properties, significantly enhancing the removal of structurally and physicochemically diverse emerging organic contaminants (EOCs). Across a broad set of experimental parameters, PEG modification consistently delivers improved separation performance for membranes. With excellent stability, high efficiency and economic feasibility, this strategy provides solid technical and theoretical support for developing advanced separation membranes targeting high-efficiency EOCs removal.

Carbon dots nanozymes were synthesized from fresh garlic and ethylenediamine. • N-CDs showed excellent photo-responsive oxidase-like activity and blue fluorescence. • N-CDs with ethylenediamine doping show higher oxidase activity than undoped CDs. • A smartphone-assisted dual-mode sensing platform was used to detect TBHQ rapidly. Synthesis of highly active carbon dots nanozymes remains challenging. Using fresh garlic and ethylenediamine as precursors, nitrogen-doped carbon dots nanozymes (N-CDs) were fabricated in this study. The N-CDs exhibited light-responsive oxidase-like activity and blue fluorescence. For comparison, the carbon dots (CDs) without ethylenediamine doping demonstrated remarkable catalytic activity. Following doping with ethylenediamine, the maximum reaction rate and specific activity of N-CDs were approximately 1.4 times and 2 times those of CDs, respectively, indicating that nitrogen doping significantly enhanced the catalytic activity. Based on the catalytic performance and fluorescence properties of N-CDs, a dual-mode sensor was constructed for the detection of tert-butylhydroquinone (TBHQ), achieving detection limits of 0.19 μM and 0.05 μM for the colorimetric and fluorescence methods, respectively. Portable on-site detection of TBHQ in real samples was realized by integrating the sensing platform with a smartphone, providing a new strategy for the preparation of high-performance nanozymes.

In situ SiO 2 growth with DA-g-C 3 N 4 co-doping yields hybrid crosslinked PA layer. • Compound strategy mitigates DA-g-C 3 N 4 aggregation in PA layer. • Achieved simultaneous gains in Mg 2+ /Li + selectivity and permeability performance. • MgCl 2 rejection stayed >93% over 160 h, demonstrating excellent long-term stability. It is often difficult for thin-film composite (TFC) nanofiltration (NF) membranes to balance high separation selectivity and high permeability, and the contradiction between the two will lead to their overall performance constraints. In this study, a dual-phase regulation strategy is proposed, which adopts the in-situ sol method and the composite strategy of introducing two-dimensional materials for the preparation of organic-inorganic cross-linked polyamide (PA) NF membranes. A trimesoyl chloride (TMC) organic phase solution containing tetraethyl orthosilicate was first introduced onto the polyethersulfone (PES) substrate, followed by contact with a polyethyleneimine (PEI) aqueous phase solution containing dopamine-functionalized carbon nitride (DA-g-C 3 N 4 ), during which silicon dioxide (SiO 2 )/Si–O–Si domains were generated in situ within the PA layer. These domains restricted the free volume of the PA layer, narrowed the effective pore-size distribution, and suppressed nonselective defects, while the embedded DA-g-C 3 N 4 improved the compatibility between the nanofillers and the PA layer, thereby producing P-1Si-0.025CN membranes with an effective pore size of 0.4 nm. Compared with the P-NF membrane prepared by reverse interfacial polymerization of TMC and PEI directly on the PES substrate, Mg 2+ /Li + separation factor (SF) increased to 67.2 (Mg 2+ /Li + mass ratio is 20), salt solution flux was 27.1 LMH, separation and permeation capacity of mixed salt was enhanced, salt solution flux has increased by 4 times, and the SF has increased by 7 times, Mg 2+ /Li + ratio decreased from 20 in feed to 0.71 in permeation process. Moreover, it exhibited excellent separation performance in diluted salt lake brine, with an Mg 2+ rejection rate exceeding 98%, and it also exhibited high fouling resistance and long-term stability.

A matrix-mimicking model strategy enables quantitative attribution of browning routes in fermented vegetables. • Ascorbic acid degradation dominated early browning and Maillard reaction dominated late. • SEM quantified Maillard reaction as the strongest direct driver of browning. • Findings translate into practical control levers for shelf-life stabilization and waste reduction in fermented products. Non-enzymatic browning during storage devalues pickled vegetables, yet roles of the Maillard reaction (MR), ascorbic acid (AA) degradation, sugar degradation and phenolic oxidation are unclear. Fourteen defined model systems (M1-M14) mimicking cowpea pickles composition were incubated at 45 °C for 40 d. Browning index and reactants, intermediates, and products were tracked. Pronounced visible browning and BI increases were mainly observed when amino acids and sugars coexisted (M3-M14), whereas amino acids (M1) or sugars (M2) alone showed limited discoloration. AA was nearly depleted by day 20 and 3-hydroxy-2-pyranone peaked at day 10 then vanished, indicating an early AA driven phase. 5-Hydroxymethylfurfural accumulated in all sugar-containing systems (16.16–98.73 μg/g at day 40) and increased continuously, marking late-stage browning. Redundancy analysis (96.75% variance) and structural equation modeling identified AA degradation (0.72) and MR (0.89) as dominant direct drivers. These results provide time-resolved compositional targets to mitigate discoloration in fermented vegetables for better quality preservation.

Synthesized Fe–KAC single-atom nanozyme on KOH-activated ZIF-8-derived porous carbon via cascade anchoring. • Developed a dual-readout CGA assay combining complementary electrochemical and colorimetric signals. • Quantified CGA in honeysuckle from five regions, with 97.20%–106.1% recoveries (n = 5) and HPLC agreement. • Enabled routine quality assessment and origin-related quality screening of honeysuckle products. As a major phenolic constituent and a key quality marker of honeysuckle ( Lonicera japonica ), chlorogenic acid (CGA) requires rapid and reliable quantification to support routine quality control of honeysuckle-derived products. Herein, we developed a portable dual-mode sensing platform with colorimetric and electrochemical readouts enabled by a single-atom iron nanozyme (Fe–KAC). Fe–KAC was synthesized via a cascade anchoring strategy on a KOH-activated MOF-derived carbon support, featuring atomically dispersed Fe sites and high surface area, which jointly impart laccase-like catalytic activity and favorable electrochemical properties. The platform enabled CGA determination over linear ranges of 0.04–100.0 μM (electrochemical) and 3.00 μM–2.0 mM (colorimetric), with limits of detection of 0.0072 μM and 0.81 μM, respectively. The electrochemical method demonstrateed good selectivity and stability, and its accuracy was validated by comparison with HPLC as well as spike-recovery tests in honeysuckle products collected from five geographical origins, yielding recoveries of 97.2% to 106.1% ( n = 5). Overall, this work presented a Fe-KAC-based complementary dual-readout sensing strategy for CGA detection, combining rapid colorimetric screening with sensitive electrochemical quantification, and showed potential applicability for the quality assessment of honeysuckle-derived products.

Fiber-shaped iontronic synapses (FEISs) are emerging as promising building blocks for next-generation wearable neuromorphic computing due to their ability to emulate biological signal transmission and plasticity. However, their practical application remains limited by poor environmental adaptability, high energy consumption, and inadequate rectification behavior. Herein, we report a FEIS with anti‑freezing capability that simultaneously achieves ultralow energy consumption and a high rectification ratio. The FEIS is constructed by directly assembling tetrachlorobenzoquinone and zinc hexacyanoferrate onto carbon nanotube fibers via π–π stacking, combined with a sucrose-modified polyacrylamide hydrogel electrolyte that inhibits ice formation through hydrogen bond regulation. Our FEIS exhibits stable synaptic operation at −20°C, with an ultralow energy consumption of 17 fJ per synaptic event, and a high rectification ratio of 17.9, enabled by asymmetric Faradaic reactions and ionic relaxation kinetics. These characteristics enable the FEIS to achieve robust unidirectional information transmission and stable synaptic operation, even under cryogenic conditions. Furthermore, the FEIS demonstrates reliable operation in ionic logic circuits and robotic control systems, achieving 95.2%-digit recognition accuracy at −20°C. This work expands the operational boundaries of flexible iontronic neuromorphic devices for applications in extreme environments.

Electrophoretic colloidal crystal displays (ECCDs) hold great potential in next-generation sustainable, low-energy full-color reflective displays, yet their practical development has been hindered by sluggish switching dynamics and poor operability at low temperatures. Here, we report a wide-temperature, low-power electrophoretic color display based on tailored carbon shell-coated polystyrene nanospheres (PS@C) in a modified deep-eutectic-solvent (MDES) dielectric medium. Under an applied electric field, PS@C nanospheres form highly ordered 3D colloidal crystals with ideal stopbands due to their narrow size distribution and high effective refractive index (∼1.67). Mimicking melanin-based photonic structures in peacock feathers, the PS@C nanospheres enable vivid structural colors with high purity and brightness. The system exhibits dynamic color switching from a dark-brown off-state to full-color states. It also enables reversible red-to-blue color modulation over a spectral range of 160 nm, with a fast tuning rate of ∼267 nm s −1 . The MDES-mediated ECCD demonstrates reliable device operation over a wide temperature range from 45°C down to −20°C. This presents unique application prospects in fields such as cold-chain logistics displays and outdoor electronic tags in cold regions.

One-pot scalable synthesis of phenylboronic acid-modified AuNPs at room temperature. • Rapid Fc-oriented antibody immobilization enabled by boronate-affinity interaction. • The oriented bio-interface enhances lateral flow immunoassay sensitivity by 16-fold. • The developed LFIA enables reliable assay of fecal occult blood in clinical samples. • This method offers a promising platform for colorectal cancer point-of-care testing. The analytical performance of lateral flow immunoassay (LFIA) is largely determined by the bio-interfacial orientation of antibodies immobilized on colloidal gold nanoparticles (AuNPs). Conventional citrate-capped AuNPs (Cit-AuNPs), however, mainly rely on random physical adsorption, which often produces unfavorable antibody orientations and poor accessibility of antigen-binding sites. In addition, Cit-AuNPs typically require harsh high-temperature reflux synthesis and specialized equipment for large-scale production, increasing industrialization costs. Here, we report a facile one-pot, room-temperature strategy for the large-scale synthesis of phenylboronic acid-modified AuNPs (PBA-AuNPs), achieving 5 L batch production within 10 min. The obtained PBA-AuNPs exhibit excellent monodisperse and a uniform size of 23.5 nm, and enable an oriented antibody immobilization via boronate-affinity interactions with the carbohydrate moieties of Fc fragments. When applied to fecal occult blood (FOB) detection, the PBA-AuNPs showed a remarkable 16-fold improvement in sensitivity compared with Cit-AuNP probes. Overall, this work provides a robust, scalable nanoplatform with strong clinical translational potential for high-sensitivity LFIA diagnostics.

Ratiometric probe (blue/yellow CDs) offers visual color change and improved accuracy. • Molecularly imprinted polymers provide high selectivity against food interferents. • Smartphone with Color Picker App enables on-site visual quantitative detection. • Successfully applied to milk and ice cream with recoveries of 95.6–104.2%. A ratiometric fluorescence sensor (B-CDs@MIPs/Y-CDs) based on blue/yellow dual-emission carbon dots and molecularly imprinted polymers was constructed for visual detection of vanillin. The addition of vanillin resulted in selective quenching of the blue fluorescence of B-CDs at 438 nm via static quenching, whereas the yellow emission at 542 nm stayed constant, leading to a progressive color shift from blue to green and ultimately to yellow. Under optimized conditions, the linear range was 2.0–120.0 μM with a detection limit of 0.22 μM. Recoveries from spiked milk and ice cream samples ranged from 95.6% to 104.2% (RSD < 1.77%). Combined with a smartphone using the Color Picker App for RGB analysis, rapid visual detection was achieved. This method is low-cost, easy to operate, and sensitive, showing great potential for food safety monitoring. Download: Download high-res image (125KB) Download: Download full-size image

Green bio-carbon aerogels were fabricated by freeze-drying and heat treatment. • Sucrose-chitosan-CNTs synergy boosts mechanical strength and thermal insulation. • Aerogel shows high strength (2.18 MPa) and low thermal conductivity (64.8 mW/m·K). • Aerogel has high oil adsorption capacity and durability (11.35 g/g after 20 cycles). Driven by the "dual carbon" goal and demand for fossil carbon alternatives, biocarbon aerogels have become a research focus for their renewability and environmentally friendly. However, most biocarbon aerogels suffer from uncontrollable pore structure, huge high-temperature volume shrinkage and poor performance synergy. Herein, chitosan (CS) and sucrose were used as the carbon skeleton to fabricate green sucrose/CS/carbon nanotube (CNTs) composite biocarbon aerogels via freeze-drying and high-heat treatment. CS’s 3D cross-linked network effectively suppressed the uncontrolled foaming of sucrose, thus enabling precise microstructure regulation of the composite biocarbon aerogel. By utilizing the structural support of CNTs, the composite biocarbon aerogel achieved simultaneous optimization of the mechanical and thermal insulation performance. After heat-treated at 1200 °C, the composite biocarbon aerogel exhibited low density (0.0773–0.1226 g/cm 3 ), high porosity (87.66%–91.88%), excellent compressive strength (0.77–12.09 MPa) and a maximum specific compressive strength of 17.79 MPa·cm 3 ·g −1 . Besides, the thermal conductivity reached as low as 0.0648 W/m·K at 25 °C, and only raised to 0.1644 W/m·K at 900 °C. Moreover, the material also showed high oil absorption capacity and ideal combustion recyclability. The synergistically multifunctional composite carbon aerogels exhibit application potential in aerospace thermal insulation and oil spill remediation, offering insights for designing multifunctional biomass carbon aerogels.

Developed an electrochemical biosensor for the bitter taste receptor TAS2R1, utilizing a nanocomposite of CMK-3 and AuNPs. • Proposed system-dependent C₁/₂,sys to quantify ligand-triggered electrochemical signals of the TAS2R1 biosensor. • H-bond & hydrophobic forces govern TAS2R1-ligand binding; Phe75, Ile254, Leu250, Phe252/259, Arg256 are key binding residues. The bitter taste receptor TAS2R1 mediates significant physiological functions not only in the gustatory system but also in extra-oral tissues, including the respiratory tract, immune system, and metabolic pathways. To elucidate its ligand recognition mechanism, we developed an electrochemical biosensor for TAS2R1 based on a composite of ordered mesoporous carbon and gold nanoparticles. The biosensor was used to quantitatively analyze the interaction kinetics with ten bitter ligands. Combined with molecular docking and molecular dynamics simulations, this study identified key residues in TAS2R1 that may be involved in ligand recognition; among these, the nitrogen-containing groups and hydroxyl groups of the ligand molecules appear to be important structural features influencing ligand recognition by TAS2R1. This work provides a molecular foundation for elucidating the structure-activity relationship of TAS2R1 and facilitates its applications in bitter taste masking and drug development.

Chemical and flavor characteristics of Lingmu tea were systematically analyzed. • Processing reshaped aroma via redistribution of key odor-active compounds. • Taste profile changed with amino acids, organic acids, and polyphenols. • Antioxidant mechanism shifted from radical scavenging to reducing capacity. Lingmu tea is a traditional non- Camellia beverage, yet its chemical basis and processing-induced changes remain unclear. This study investigated the effects of processing on its composition, flavor, and antioxidant properties using metabolomic and sensory analyses. Processing significantly reduced free amino acids and flavan-3-ols such as epigallocatechin, while increasing complex polyphenols including terchebin and trigalloyllevoglucosan. Organic acids such as gallic acid and lactic acid also increased. Volatile analysis based on relative odor activity values showed that linalool (ROAV = 100) was the dominant aroma contributor in fresh leaves, whereas 1-octen-3-one (ROAV = 100) and dimethyl sulfide (ROAV = 61.75) showed higher contributions after processing. Notably, antioxidant activity exhibited a mechanistic shift from rapid radical scavenging to enhanced overall reducing capacity. These findings provide insights into the compositional and functional transformation of Lingmu tea during processing. Download: Download high-res image (139KB) Download: Download full-size image
