To solve the problem of white pollution and petroleum energy consumption, zein/PVA blended fibers were prepared by wet-spinning technology to replace petroleum-based synthetic fibers. Zein has the environmentally friendly and resource-abundant characteristics, but its low viscosity makes it difficult to process via wet-spinning. By enabling the successful wet-spinning of inherently poorly spinnable zein, the introduction of PVA yielded blended fibers that retained more than 81% of the zein content. The zein/PVA blended fibers exhibit a maximum tensile strength of 32.38 MPa, a maximum elongation at break of 561.80%, a moisture regain of 4%, and a dye-uptake rate of 59.68%. This work lays the foundation for using zein/PVA blended fibers as a sustainable alternative to petroleum-based synthetic fibers in the textile industry.

Interfacial water plays a crucial role in charge transfer and energy conversion at the semiconductor–liquid junction. Here, we firstly demonstrate that TiO 2 with varied crystal phases generates a region of particle-free and negatively charged water at the TiO 2 –water interface without light. Upon irradiation, a mixed-phase TiO 2 electrode (anatase: rutile ≈ 7:3) paired with FTO generated a stable photovoltage of 0.32 V in deionized water without any added redox couples. This photovoltage correlates with surface hydrophilicity as well as crystal-phase composition, revealing a previously overlooked interplay between TiO 2 and interfacial water. These experimental findings not only provide new insights into photoinduced charge dynamics and self-cleaning mechanism at the TiO 2 –water interface, but also suggest an alternative pathway for light-to-electrochemical energy conversion directly from water.

The inherent flammability, poor mechanical property and non-recyclability of vinyl resins (VER) has hindered their widely use in aerospace and construction applications. In this work, inspired by the soil-root-mineral synergy in natural ecosystems, a novel P-N flame retardant (AT) was covalently immobilized within the polymer matrix, mimicking root anchoring in soil. Concurrently, functionalized glass fibers (FGF) were incorporated, analogous to mineral particles, to synergistically enhance the flame retardancy and mechanical reinforcement for VER. When incorporating 14 wt% AT and 1 wt% FGF, the composite achieved a UL-94 V-0 rating with a limiting oxygen index (LOI) of 31.3%. Cone calorimetry test (CCT) revealed that the VERAT/FGF 1 composite exhibited significant reductions in heat release rate (HRR), total heat release (THR), and smoke production rate (SPR) of 54.4%, 39.3%, and 20.1%, respectively, compared to pure VER. Comprehensive analyses demonstrated that the flame-retardant mechanism involved synergistic effects in both condensed and gas phases. Simultaneously, the VERAT/FGF 1 composite demonstrated 41.9% and 10.7% enhancements in tensile strength and impact resistance, respectively, compared to neat VER. Chemical degradation of VERAT/FGF 1 by solvent method for efficient recycling of glass fibers, providing a new strategy for reuse of vinyl polyester composites.

This study presents a malic-acid-mediated chelation strategy for preparing high-solid-content, aggregation-resistant yttrium sols tailored for titanium–aluminide investment casting. By systematically tuning the molar ratios of YCl 3 , Y(OH) 3 , and malic acid, the coordination structure and colloidal stability were clarified. Under optimal conditions (YCl 3 :Y(OH) 3 = 10:2; Y(OH) 3 :malic acid = 1:2), malic acid coordinated with yttrium through combined monodentate and bidentate modes, forming stable five- and six-membered chelate rings that effectively suppressed hydrolysis. The optimized sol achieved a solid content of 26.70 % with a zeta potential of 27 mV. In contrast, acetic, oxalic, and acrylic acids predominantly formed monodentate complexes, resulting in inferior stability. A critical solid-content threshold was identified, beyond which rapid gelation occurred. To enhance sol uniformity and mitigate the adverse effects of residual chloride ions during shell fabrication, the sol was dialyzed for 30 min in a pH 3.5 malic acid solution. After dialysis, the sol retained a solid content above 24 %, exhibited a zeta potential of 27.3 mV, and showed uniformly distributed spherical particles with an average size of 75 nm, confirming excellent stability and suitability for investment casting applications.

In this study, polysaccharides from Zanthoxylum schinifolium Siebold and Zucc. leaves (ZLPs) were obtained through five extraction methods: hot water extraction (HWE-CPS), ultrasound-assisted extraction (UAE-CPS), enzymatic extraction (EAE-CPS), microwave-assisted extraction (MAE-CPS), and microwave–enzyme co-assisted extraction (MA–EAE-CPS). Structural analysis showed that ZLPs consist mainly of galacturonic acid (30.34 mol%–34.24 mol%) and galactose (33.94 mol%–37.59 mol%), with molecular weights ( Mw ) ranging from 1648 to 3859 kDa. Ultrasound-assisted extraction reduced the Mw . All the ZLPs resisted degradation under simulated gastrointestinal conditions, with UAE–CPS exhibiting the strongest resistance and EAE–CPS the weakest. The prebiotic potentials of HWE–CPS, UAE–CPS, and MA–EAE–CPS were assessed by in vitro colonic fermentation. After 48 h, all the samples were extensively degraded, and the microbial composition (pH declined to 6.13, 5.58, and 5.50) led to a significant increase in Bacteroidetes and a decrease in Proteobacteria. Fermentation also elevated short-chain fatty acids (SCFAs) levels, with UAE-CPS yielding the highest total SCFAs concentration (42.42 mmol/L). Correlation analysis indicated that the ratio of the RG-I domain was positively correlated with the abundance of certain beneficial microorganisms and the production of SCFAs. These findings provide valuable insights into polysaccharide extraction from plant leaves and provide a reference for the application of ZLPs as functional prebiotic ingredients.

In modern liquid chromatography, versatile mixed-mode stationary phases have emerged as a practical choice for complex separations. Glucamine is promising in this field due to its distinctive amino-substituted glucose structure. This work presents a novel alkyl glucamine-based stationary phase (SIL–GNOGA) prepared via an epoxide-amine ring-opening reaction and immobilized onto silica surfaces. The morphology and composition of the stationary phase were characterized by multiple analytical techniques. Its retention mechanism was systematically investigated using analytes with diverse properties under varied chromatographic conditions. Furthermore, the separation performance of SIL–GNOGA was assessed and compared against its alkylamine- and glucamine-based counterparts. The stationary phase demonstrated excellent versatility, enabling efficient separation of hydrophilic, hydrophobic, as well as amphiphilic analytes in hydrophilic interaction or reversed-phase mode, depending on their molecular characteristics. Notably, complex mixtures were successfully resolved in both modes through the synergistic effects of hydrophilic, hydrophobic, hydrogen-bonding, and electrostatic interactions. This mixed-mode capability highlights SIL–GNOGA’s broad selectivity and potential across diverse chromatographic applications.

Nitrogen-doped carbon dots (N-CDs) exhibiting long-wavelength fluorescence were successfully synthesized via a one-step hydrothermal method using neutral red and thiosemicarbazide as precursors, specifically to address limitations in pyrophosphate (P 2 O 7 4− , PPi) detection. As an essential adenosine triphosphate (ATP) hydrolysis byproduct and disease biomarker, PPi quantification remains challenged by costly instrumentation and complex procedures in conventional methods. The synthesized N-CDs demonstrated optimal excitation/emission at 520/600 nm with a quantum yield (QY) of 4.8%, enabling rapid (1 min response time), selective PPi detection through fluorescence quenching. Quantitative analysis revealed a linear detection range of 1.38–85.60 μmol/L (R 2 = 0.9983) and low detection limit of 0.42 μmol/L. Practical validation in milk samples yielded excellent recovery rates of 95.26–105.74% with ≤1.86% relative standard deviation, confirming reliability in complex matrices. Critically, the N-CDs' deep-tissue penetration capability facilitated real-time monitoring of intracellular PPi dynamics in HeLa cells, while maintaining high biocompatibility. This work establishes multi-element doped carbon dots as both a cost-effective analytical alternative and a versatile platform for biomedical imaging applications.

A reflective optical fiber gas sensor was developed for the accurate detection of acetic acid gas concentrations in real time. This sensor comprises a multimode quartz optical fiber and a sensing unit coated with a material that selectively responds to acetic acid. The sensing unit consists of a light channel coated with a Ag film, on which a composite film of TiO 2 /functionalized zirconium metal-organic framework (UiO-66–2CF 3 ) is deposited. Upon absorbing acetic acid, the refractive index of the TiO 2 /UiO-66–2CF 3 film increases, enhancing the light absorption at 326 nm while reducing the reflectance. This decrease in the transmitted light intensity enables the accurate measurement of the environmental acetic acid concentration by detecting the difference between the output and input optical intensities. Experiments were performed to investigate the dependence of the sensor performance on the TiO 2 content in TiO 2 /UiO-66–2CF 3 , coating thickness, light incidence angle in the optical channel, and ambient temperature and humidity. In the range of 10–40 °C and 40–80 % RH, the sensor with 45 wt% TiO 2 in the composite, a coating thickness of 55 μm, and an incident angle of 45° yielded an acetic acid gas response sensitivity of 0.0007 absorbance unit/ppm, a response time of 315 s, detection limit of 4.29 ppm, and maximum relative error below 5.0 %. The incorporation of the –CF 3 group into UiO-66 endowed the sensor with excellent humidity immunity, a high selectivity for acetic acid, and long-term stability.

Lightweight porous aerogels have demonstrated efficient electromagnetic wave absorption performance. Nevertheless, the inherent trade-off between favorable impedance matching at the atmosphere-aerogel interface and strong electromagnetic loss within the aerogel matrix has limited the further improvement of the aerogel's electromagnetic wave absorption performance. In this study, a waxberry-inspired gradient-porous aerogel metamaterial (WGAM) was successfully fabricated via an innovative dot-matrix cooling source ice templating technique. The influences of diverse pore structures and repeating unit sizes on the performance of aerogels were systematically investigated and analyzed. The results reveal that the gradient pore structure in WGAM effectively balances the conflict between interface impedance matching and intrinsic electromagnetic loss, enabling WGAM to achieve an ultrabroad effective absorption bandwidth of 12.3 GHz within the range of 2–18 GHz. Meanwhile, owing to the 3D radial distribution of internal pores, WGAM retains robust electromagnetic wave absorption capacity even when the incident angle of electromagnetic waves is increased from 5° to 30°. Furthermore, WGAM exhibits favorable mechanical, thermal-insulating, and flame-retardant properties, rendering it a promising candidate for electromagnetic protection applications under complex and harsh environmental conditions.

As an important and free amino acid, taurine (Tau) shows extensive application in pharmaceuticals. The coexistence of inorganic salts during the production process affects the purity and quality of Tau. Present study firstly described a novel method to separate Tau and Na2SO4 by forming deep eutectic solvents (DESs) in situ. Ethanolamine (MEA) was chosen as the optimal hydrogen bond donor to pair with Tau. After removal of Na2SO4, taurine was stripped out from in situ DES using n-propanol as reverse solvent with the yield of 98% and trace impurities (Na2SO4 and NaCl contents less than 13.70 mg•g -1 and 12.93 mg•g -1 , respectively). On the optimized parameters, the Tau purification and separation process were further elucidated using quantum chemical calculations and molecular dynamics simulations together. Results showed the interaction energy of 116.1 kJ/mol between MEA and Tau, confirming the superiority of Tau purification using DES in situ.

Polyurethane sizing agents are widely applied in solving interface issues in carbon fiber composites. Influenced by the concept of sustainable development, the scientific community has been seeking a non-isocyanate green synthesis route for polyurethane to replace traditional petroleum-based polyurethane for decades. This article uses epoxidized soybean oil and CO 2 to prepare carbonated epoxidized soybean oil, and synthesizes a non-isocyanate polyurethane through five-membered cyclic carbonate aminolysis for the development of a green and efficient water-based non isocyanate polyurethane (BNIPU) sizing agent for constructing the “rigid-flexible” green interface of composites. The use of isocyanates in synthesis has been eliminated, achieving environmental friendliness and high efficiency. BNIPU sizing agent efficiently improves the interfacial properties of CF/EP composite materials. After evaluation, the IFSS and ILSS of the modified CF 20 /EP composite reached 127.69 MPa and 96.22 MPa, respectively. Compared to the composite material without sizing, the improvement was 125.28% and 80.05%, respectively. This paper provides a new approach for a novel green synthesis route for polyurethane and suggests the possibility of partially replacing traditional polyurethane.

PiRNAs have emerged as promising biomarkers for cancer diagnosis, however, their sensitive detection remains challenging due to the reliance on enzymatic amplification, complex labeling procedures. Herein, we report an integrated sensing strategy that combines a structure-switching ratiometric nano-converter with an enzyme-free entropy-driven catalytic (EDC) DNA circuit for highly sensitive and reliable piRNA detection. A hairpin DNA templated silver nanocluster (HP-DNA-AgNCs) that functions as a programmable nano-converter. In its closed hairpin state, the probe exhibits strong green fluorescence (530 nm). Upon hybridization with the target piRNA, the hairpin undergoes a structural transformation, triggering AgNC redistribution and a pronounced fluorescence shift to red emission (620 nm), thereby generating a ratiometric signal (F 620 nm / F 530 nm ). Notably, this structural transition is rationally coupled to an EDC amplification circuit, enabling each target piRNA to catalytically activate multiple nano-converters under isothermal conditions. Current method allows ultrasensitive piRNA detection with a limit of detection as low as 0.146 pM and a wide dynamic range. The clinical applicability of the platform was further validated using breast cancer tissue samples, yielding an area under the ROC curve (AUC) of 0.951, in excellent agreement with qRT-PCR analysis. By unifying ratiometric self-calibration, enzyme-free amplification, and label-free design, this work establishes a robust and versatile sensing paradigm with strong potential for clinical diagnostics and point-of-care testing.
