Plant essential oil-based pesticides are increasingly valued in green agriculture for their efficacy, environmental compatibility, low toxicity, and minimal impact on non-target organisms. However, their practical use remains limited by short efficacy periods, poor photostability, and low solubility. To overcome these limitations, this study developed a pH-responsive hydrogel composed of carvacrol and the natural polysaccharides chitosan (CS) and guar gum (GG), which improved photostability by 126 %. The CS-GG hydrogel exhibited accelerated carvacrol release under acidic conditions, showing a relative increase of 20 % and following a Weibull diffusion model, thereby enabling targeted drug delivery at infection sites. Encapsulation markedly enhanced antifungal performance against anthracnose, achieving superior mycelial inhibition on tomato surfaces in both preventive and curative treatments compared with unencapsulated carvacrol. Moreover, hydrogel encapsulation reduced acute toxicity by minimizing direct exposure, as reflected by zebrafish LC 50 values that increased by approximately 71 % at 48 h and 46 % at 96 h, thereby significantly improving ecological safety. These findings demonstrate that the pH-responsive CS-GG hydrogel offers a promising platform for controlled delivery of botanical pesticides. This approach not only provides an effective, environmentally friendly solution for anthracnose control but also establishes a versatile framework for advancing the application of other plant-derived pesticides in sustainable crop protection.

AimsThis study aimed to investigate the capacity of lactic acid bacteria (LAB) isolated from yak calves to metabolize xylo-oligosaccharides (XOS) and to identify potential probiotic strains that could enhance the gut health of yak calves.Methods and ResultsLAB isolates were recovered from fifteen fecal samples collected from yak calves. Their capacity to utilize XOS as the sole carbon source was evaluated, and their metabolic characteristics, molecular mechanisms, and functional properties associated with XOS metabolism were examined through integrated phenotypic and genomic analyses. Consequently, forty-one LAB isolates were identified from ten of the fifteen yak calves and tested for XOS utilization. Among these, 51.22% (21/41) exhibited species- and strain-specific XOS utilization, including Limosilactobacillus mucosae (10 isolates), Lactobacillus brevis (10 isolates), and Lactiplantibacillus plantarum (1 isolates). L. mucosae YT200 showed the highest acid production (pH 4.50) and short-chain fatty acid accumulation, particularly acetic acid (745.00 ± 16.24 mM). Genomic analysis revealed three gene clusters encoding GH43 α-L-arabinofuranosidase, GH51 α-L-arabinofuranosidase, and GH43 β-xylosidase, enabling the hydrolysis of arabinosyl-substituted and linear XOS. Strain YT200 also demonstrated antagonism against common gut pathogens including Escherichia coli and Staphylococcus aureus, sensitivity to seven antibiotics, and no transferable resistance genes.ConclusionThis study reveals the mechanistic basis of XOS metabolism in L. mucosae YT200 and identifies L. mucosae YT200 as a promising candidate for synbiotic development.

This study investigated the formation of harmful Maillard reaction products (MRPs), particularly advanced glycation end products (AGEs) and 1,2-dicarbonyl compounds, in fried shiitake mushroom crisps prepared from ten types of Lentinula edodes , in relation to their inherent chemical components. Analyzed harmful MRPs included 1,2-dicarbonyls (3-deoxyglucosone/3-DG, glyoxal/GO, methylglyoxal/MGO, diacetyl/DA), hydroxymethylfurfural/HMF, and AGEs (carboxymethyllysine/CML, carboxyethyllysine/CEL, methylglyoxal-derived hydroimidazolone1/MG-H1). Results revealed the positive effect of glucose, 3-DG, Asp, Arg, and Lys on the HMF levels. Conversely, ergothioneine negatively correlated with 3-DG, DA, MGO, CML, and CEL; vanillic acid and caffeic acid were inversely related to GO and MG-H1, respectively. Additionally, Ser positively correlated with CML, while CEL had significant negative correlations with Asp, Gly, and total free amino acid. Overall, there was a complex relationship between the chemical components and harmful MRPs in fried shiitake crisps, with ergothioneine, caffeic acid, and vanillic acid showing potential inhibitors of AGEs and 1,2-dicarbonyls generation.

Methamphetamine (METH) is a potent psychostimulant with a high potential for addiction, ranking among the most prevalent and frequently abused illicit substances worldwide. Thus, the development of rapid and precise methodologies for METH detection is essential for law enforcement and public health monitoring. This study reported the first construction of a molecularly imprinted fluorescence sensor utilizing EDTA-Cu quantum dots (EDTA-Cu QDs-MIP) for the fluorescence quantification of methamphetamine. The sensor displayed a linear response within a concentration range spanning from 53 to 371 nM, achieving a limit of detection (LOD) equal to 20.6 nM through fluorescence spectroscopy. Validation with real-world samples confirmed the sensor's high accuracy, with recovery rates in the range from 97.2 to 104.4 %. This study not only broadens the scope of QDs in chemical detection but also introduces a strong and portable platform for forensic investigations and on-site screening of illicit drugs.

In this paper, Ce-Zr oxide ceramic fiber aerogels (CZOf) with effective thermal insulation properties were successfully prepared by a simple two-step method of solution blow spinning and pyrolysis. In the spinnable precursor cerium-zirconium carboxylate, the organic carboxylic acid ligands and metal inorganic salts enhanced its structural stability through coordination interactions. The effect of thermal treatment temperature and Ce doping amounts on the crystal structure of CZOf were analyzed based on XRD. At the same time, the microstructures of the CZOf heat treated at different temperatures were analyzed by SEM in detail. In addition, CZOf exhibited a compressive stress of 24.9 kPa under 80 % compressive strain, and still showed a compressive stress of 20.2 kPa after 20 compression cycles. The room-temperature thermal conductivity of CZOf was in the range of 31.4–38.3 mW m −1 K −1 . The CZOf with a thickness of 10 mm could reduce the hot surface temperature from 1200 °C to about 210.5 °C after 10min, demonstrating excellent thermal insulation performance.

Electrocatalytic nitrate reduction to ammonia (NRA) is a promising technology for water remediation, but its application to environmentally relevant low concentrations (< 20 ppm) is severely hampered by mass transport limitations and low selectivity. This study introduces a novel strategy combining pulse electrocatalysis with a tailor-made iron-decorated copper foam (Fe@CF) electrode to overcome these challenges. When applied to 20 ppm nitrate solution, the system under optimized pulse conditions demonstrated a remarkable performance, achieving 99 % nitrate removal efficiency and 96 % ammonia selectivity within 150 min, resulting in an ammonia yield of 93 μg·h⁻¹ ·cm⁻². This represents a significant enhancement over conventional direct current (DC) electrolysis, which suffered from substantial nitrite accumulation. Characterization confirms that Fe nanoparticles, acting as tandem catalytic sites, were uniformly deposited on the porous Cu foam. The superior performance is attributed to a dual-enhancement mechanism: (1) the pulsed potential effectively alleviates mass transport limitations by facilitating reactant replenishment and product desorption, and (2) the synergistic effect between Cu and Fe sites promotes the rapid conversion of nitrite intermediates to ammonia. This work highlights that integrating advanced electrode design with pulse electrocatalysis is a potent approach for efficient and selective nitrogen recovery from dilute nitrate-contaminated water.

Medium chain triglycerides (MCTs) are regarded as an important ingredient for functional foods and nutraceuticals.Cinnamomum camphoraseed kernel oil (CCSKO) contains more than 95% medium chain fatty acids (MCFAs), which is a significantly higher level than palm kernel oil (62%) and coconut oil (55%). However, the safety assessment of CCSKO, as the only natural MCT oil rich in capric acid and lauric acid found so far in the world, has not been fully verified. The study aimed to investigate the 90-day sub-chronic oral toxicity and teratogenicity of CCSKO. In the sub-chronic oral toxicity study, no clinically significant adverse events occurred in male or female Sprague–Dawley (SD) rats with CCSKO daily administration for 13 weeks. Moreover, there were no dose–response relationships between CCSKO and body-weight gain, food intake and food utilization in male or female SD rats. No significant differences (p> 0.05) were found in the hematological properties or organ weights between the male and female SD rats. In the teratogenicity test, no toxicological signs were observed in either Wister pregnant rats or fetuses. The no-observed-adverse-effect level of CCSKO was determined to be more than 4 mL/kg body weight. These results suggested that CCSKO may be an excellent edible oil with high oral safety.

The main challenge to the use of vegetable oils as green lubricants is their oxidative stability. In this work, biolubricants with efficient antioxidant properties have been specifically designed and synthesized with the aim of maximizing the oxidative stability of vegetable oils by combining biophenols (p-coumaric, ferulic, and sinapic acids) with epoxidized ring-opened soybean oil in a single molecule. The synthetic products were named OIS-ESO-PCA (epoxidized ring-opened soybean oil grafted with p-coumaric acid), OIS-ESO-FA (epoxidized ring-opened soybean oil grafted with ferulic acid), and OIS-ESO-SA (epoxidized ring-opened soybean oil grafted with sinapic acid), respectively. Biophenols improve biolubricant antioxidant properties, addressing energy, and environmental challenges. The modified samples were characterized by Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR). The free radical scavenging activity of the oil samples was evaluated using the DPPH (1,1-diphenyl-2-trinitrophenylhydrazine) method and was found to be much higher than that of the soybean oil (SBO). The oxidation resistance and thermo-oxidative stability of the oil samples were evaluated based on pressure differential scanning calorimetry (PDSC), rotary bomb oxidation test (RBOT), and thermogravimetry (TGA). Compared with SBO, the oxidative induction time of OIS-ESO-PCA, OIS-ESO-FA, and OIS-ESO-SA increased by 118%, 296%, and 384%. The modified oils showed excellent antioxidant properties compared to the SBO. Therefore, biophenolic acid can be effectively used to improve the antioxidant properties of vegetable oils. Graphical Antioxidant capacity of bio-phenolic oil samples.

Soybean sprouts are a popular and nutrient-dense traditional food in several countries; thus, they are susceptible to numerous infectious diseases during germination. This study examined the impact of methyl jasmonate (MeJA) at concentrations of 100 and 300 μM on isoflavone levels, antioxidant activities, and disease index against Fusarium sulawense in soybean sprouts. The application of 300 μM MeJA resulted in a 26 % reduction in the disease index of F. sulawense -infected soybean sprouts after 7 d of germination. The isoflavone content in MeJA-treated soybean sprouts increased, particularly on day 5 (7.71–9.57 g kg −1 ). Ten isoflavones were quantified, with genistin (∼1.3 g kg −1 ) being the most abundant and acetyl daidzin (∼0.19 g kg −1 ) the least abundant. On day 5, superoxide dismutase (SOD) and catalase (CAT) exhibited peak levels of 117 and 193 kU kg −1 , respectively, in F. sulawense -infected soybean sprouts when treated with 100 μM MeJA. The total phenolic content (TPC) in MeJA-treated soybean sprouts increased by 2-fold from day 1 to day 7, except for F. sulawense treatment. MeJA boosted the expression of several isoflavone biosynthesis-related genes in germinated soybeans, including PAL , C4H , 4CL , CHS , IFS , and CHI . Collectively, this study suggests that the application of MeJA in F. sulawense -infected soybean sprouts may enhance isoflavone biosynthesis and antioxidant activities.

In this study, a dual-network, dynamically cross-linked composite hydrogel was developed for wound closure and healing. The combined action of dopamine iron coordination reaction and Schiff base linkage between dopamine-modified oxidized hyaluronic acid (OHA) and polyacrylamide (PAM) was employed to form a dual-network, dynamically cross-linked structure in hydrogel. Then viscid germander herb (Vgb) extracted from total saponins was incorporated into the composite hydrogel to fabricate hydrogel wound dressing. The resultant hydrogel wound dressing demonstrated good biocompatibility in accelerating cell proliferation and migration. In vivo results demonstrated that compared with commercial dressings, the resultant hydrogel wound dressing facilitated wound healing on an infected full-thickness skin defect model by upregulating the gene expression of growth factors such as CD-31 and downregulating that of inflammatory factor IL-6. The transcriptomic results revealed that the biological mechanism by which Vgb regulated NF-κB and the innate immune system signaling pathways in the wound closure and healing processes.

While non-contact magnetic fields have been widely employed as stimuli for modulating magnetic, electric, and catalytic properties , their direct influence on gas sensing processes remains unexplored. The renaissance of multiferroics , whose surface electric polarization can be magnetically controlled via intrinsic magnetoelectric coupling effect, offers the possibility to manipulate gas sensing properties through magnetic field. Here, we investigated the effect of the external magnetic field on gas sensing performance using the most representative multiferroic material. Our experimental results demonstrate that the Bi 0.92 Dy 0.08 FeO 3 sensors exhibit a non-linear magnetic field-controlled acetone sensing performance. When the Bi 0.92 Dy 0.08 FeO 3 sensor is exposed to a 140 mT magnetic field, its gas response towards 100 ppm acetone rises from 12.7 to 20.3, reaching a 60 % increase. The response time decreases from 53 to 41 s, corresponding to a 113 % increase in reaction rate constant. These improvements are attributed to the magnetoelectric coupling effect, which induces surface uncompensated polarization and enhances domain conductivity, thereby promoting surface oxygen chemisorption and charge carrier transport. Our findings not only advance the fundamental understanding of magnetically tunable gas sensors but also broaden the potential applications of multiferroic materials.

Fermented salt-free bamboo shoots, a traditional fermented vegetable product, are esteemed in southern China for their unique flavor and aroma. The distinctive taste of these shoots is attributed to the volatile organic compounds (VOCs) and organic acids produced during fermentation. This study explored how organic acids and VOCs change over a 60-day fermentation period. The findings revealed notable variations in pH, total sugars, and organic acids throughout the process. Utilizing GC-IMS (gas chromatography-mass spectrometry) analysis, 65 volatile organic compounds (VOCs) were detected, which comprised alcohols, aldehydes, esters, ketones, and aromatic compounds. The concentration and composition of VOCs changed significantly during the fermentation process. Esters and aldehydes were the predominant VOCs. The changes in organic acids levels were correlated with the production of specific VOCs, indicating complex interactions between organic acids and VOCs during the fermentation process. Employing correlation analysis and OPLS-DA (orthogonal partial least squares discriminant analysis), we identified 14 pivotal volatile organic compounds (VOCs) and organic acids that exert the most significant influence on the flavor profile of fermented salt-free bamboo shoots. This study provides invaluable insights for enhancing both the processing and economic potential of bamboo shoots.
