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.

The catalytic performance of TS-1 zeolites in selective oxidation reactions is strongly influenced by both the TiO6 concentration and specific surface area. However, simultaneously optimizing these two critical factors remains a significant challenge. Herein, a biuret-assisted hydrothermal synthesis strategy was developed to fabricate hierarchical TS-1 zeolites with high TiO6 concentration and enhanced specific surface area. The interaction between the amide groups of biuret and Ti monomers promoted the formation of TiO6 during crystallization, while the confinement effect of biuret facilitated the construction of mesopores. The resulting hierarchical TS-1 exhibited good catalytic activity and stability towards 1-hexene epoxidation and oxidative desulfurization reactions, where the conversion was 1.41 and 3.36 times higher than that of conventional TS-1, respectively. This work provides a facile approach for designing high-performance TS-1 catalysts by dual regulation of active sites and porosity.

Zinc metal is recognized as a highly promising anode material for aqueous zinc-ion batteries due to its high theoretical capacity and favorable oxidation-reduction potential. Nevertheless, uncontrolled zinc dendrite growth and side reactions pose critical challenges to their practical applications. Herein, the amide groups are introduced into microporous polymers (PIM-CONH 2 , denoted PC) via amine functionalization and applied as a surface engineering coating for zinc anodes. The functionalization of amide groups enhances the zincophilicity of the polymer coating through coordination interactions with Zn 2+ , while also forming hydrogen bonds with water molecules to reduce solvation and prevent side reactions. Additionally, the microporous structure of PIM-CONH 2 facilitates the uniform distribution of Zn 2+ , promoting more even ion flow, enhancing dendrite-free zinc deposition, and improving electrochemical stability. Consequently, the PC@Zn||PC@Zn symmetric battery achieves prolonged cycle stability over 1250 h at 0.5 mA cm −2 /0.5 mAh cm −2 . The PC@Zn||Cu asymmetric battery exhibits stable zinc plating/stripping over 2200 cycles at 2.0 mA cm −2 /1.0 mAh cm −2 and achieves an average CE of 99.8 %, which exhibits exceptional Zn plating/stripping reversibility. The PC@Zn||NVO full battery demonstrates outstanding cycling performance, retaining 72 % specific capacity retention after 2000 cycles at 10 A g −1 . This work establishes a generalizable strategy for high-performance zinc metal anodes through rational design of functional microporous polymer interfaces, opening new avenues for sustainable energy storage systems.

Cardiovascular diseases pose a significant global health threat, and stents play a crucial role in managing these diseases. However, challenges exist with respect to the poor adhesion of stent coatings. Cardiac stents are often composed of titanium–nickel (TiNi) alloys as the metallic component and poly(n-butyl methacrylate) (PBMA) as the coating. The poor adhesion of PBMA to TiNi alloy surface may cause detachment and subsequent thrombosis post-implantation. This study utilizes Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization to synthesize a novel block copolymer, PBMA-b-PVP, composed of PBMA and poly(N-vinylpyrrolidone) (PVP). TiNi alloy surfaces are functionalized with polydopamine (PDA) to enhance polymer coating adhesion. PBMA-b-PVP exhibits a remarkable improvement in adhesion from class 5 to class 0 and high coating stability after a 15 days immersion in a phosphate buffer solution. The corrosion current density is reduced by 44% with the incorporation of PDA into PBMA-b-PVP coatings, suggesting high corrosion resistance. PDA-functionalized coatings promote cell viability without cytotoxicity, suggesting high biocompatibility. This study provides a robust strategy for preparing stent coatings with high adhesion, corrosion resistance, and biocompatibility.

Active food packaging films with biological activities are a promising food technology, and antioxidant ability is one of the most important biological activities. In this study, an antioxidant active packaging film was prepared by directly blending gelatin, chitosan and a novel O/W Pickering emulsion and then drying. The emulsion was prepared from two antioxidant compounds, Mesona Chinensis essential oils (MCB-EO) and betanin-loaded quaternary ammonium-functionalized mesoporous silica nanoparticles (betanin-QAMSNPs), which provide this emulsion with high antioxidant activity. After adding the emulsion, the water content (26.63 %), water solubility (28.3 %), and water contact angle (86.2°) of the film are lower than those of the gelatin-chitosan film. The thickness and water vapour permeabilities of the betanin-Pickering emulsion film are 275.25 µm and 4.802 × 10 −10 g·s −1 ·m −1 ·Pa −1 , respectively, which are higher than those of gelatin-chitosan films. Adding betanin-Pickering emulsions can decrease the roughness of the surface, which is observed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The DPPH and ABTs + free radical scavenging capacities of the betanin-Pickering emulsion films are 21.77 % and 91.87 %, respectively, which are higher than those of the gelatin-chitosan films (4.64 % and 61.15 %), indicating that adding the betanin-Pickering emulsion can enhance the antioxidant ability of the gelatin-chitosan films. The betanin-Pickering emulsion films can inhibit the oxidation of soybean oil. In conclusion, in this study, a novel food packaging film was successfully prepared and has potential application as an antioxidant food packaging material.

Natural products-based screening of active ingredients and their interactions with target proteins is an important ways to discover new drugs. Assessing the binding capacity of target proteins, particularly when multiple components are involved, presents a significant challenge for sensors. As far as we know, there is currently no sensor that can accomplish high-throughput quantitative analysis of natural product-target protein binding capacity based on Raman spectroscopy. In this study, a novel sensor model has been developed for the quantitative analysis of binding capacity based on Surface-Enhanced Raman Spectroscopy (SERS) and Photocrosslinked Molecular Probe (PCMP) technology. This sensor, named SERS-PCMP, leverages the high throughput of molecular probe technology to investigate the active ingredients in natural products, along with the application of SERS labelling technology for target proteins. Thus it significantly improves the efficiency and accuracy of target protein identification. Based on the novel strategy, quantitative analysis of the binding capacity of 20 components from Shenqi Jiangtang Granules (SJG) to α-Glucosidase were completed. Ultimately, the binding capacity of these active ingredients was ranked based on the detected Raman Intensity. The compounds with higher binding capacity were Astragaloside IV (Intensity, 138.17), Ginsenoside Rh2 (Intensity, 87.46), Ginsenoside Rg3 (Intensity, 73.92) and Ginsenoside Rh1 (Intensity, 64.37), which all exceeded the binding capacity of the positive drug Acarbose (Intensity, 28.75). Furthermore, this strategy also performed a high detection sensitivity. The limit of detection for the enzyme using 0.1 mg of molecular probe magnetic nanoparticles (MP MNPs) was determined to be no less than 0.375 μg/mL. SERS-PCMP sensor integrating SERS labeling and photocrosslinked molecular probes which offers a fresh perspective for future drug discovery studies. Such as high-throughput drug screening and the exploration of small molecule-target protein interactions in vitro.

The treatment of wastewater laden with energetic compounds, particularly 2,2′,4,4′,6,6′-hexanitrostilbene (HNS), remains highly challenging owing to the environmental persistence and inherent toxicity of nitroaromatic derivatives. Herein, we reported a CoFe 2 O 4 /PMS system for the first-time efficient degradation of HNS. The CoFe 2 O 4 /PMS process afforded 96.3% removal of HNS within 150 min, together with 89.3% chemical oxygen demand (COD) removal and 49.5% total organic carbon (TOC) removal, indicating substantial deep oxidation and partial mineralization. Mechanistic studies combining quenching experiments, EPR spectroscopy, electrochemical analysis, and DFT calculations disclosed a synergistic radical/non-radical pathway dominated by 1 O 2 , with Fe incorporation enhancing PMS adsorption, charge transfer, and catalytic activation. HPLC-MS revealed degradation intermediates and supported three plausible degradation pathways, whereas QSAR analysis indicated progressive detoxification during oxidation. The catalyst further exhibited excellent stability, negligible metal leaching, and broad applicability toward actual HNS production wastewater and other energetic organic pollutants. These findings identify CoFe 2 O 4 /PMS as a promising platform for the efficient remediation of hazardous energetic compound wastewater.

Gas separation using metal organic framework (MOF) membranes has attracted considerable attention in recent years. Despite the progress made, establishing thin, defect-free MOF layers within the porous polymer remains a significant challenge. In this study, a novel approach is reported for the preparation of ZIF-8/Polyethersulfone (ZIF-8/PES) composite membranes via non-solvent-induced phase separation (NIPS)-triggered in-situ crystallization strategy. In this method, PES serves as a solid solvent for Zn(NO 3 ) 2 . During the NIPS process, an asymmetric PES membrane with a skin layer, finger-like pores, and interconnected foam structures is formed. Concurrently, Zn(NO 3 ) 2 diffuses to the skin layer and reacts with 2-methylimidazole (2-MIM), yielding a dense ZIF-8 layer on the PES surface. The simultaneous nucleation and growth of ZIF-8 within the polymer create strong interfacial interactions at the organic-inorganic interface. These interactions improve the compatibility between ZIF-8 and the polymer matrix, reduce interfacial defects. As a result, the composite membrane exhibits enhanced mechanical stability. When the crystallization time is extended to 48 h, the thickness of the ZIF-8 layer reaches approximately 540 nm, and the membrane exhibits an H 2 /CO 2 selectivity of 72.3 ± 3.35 at 298 K. This study provides a facile and effective route for constructing thin MOF membranes on polymeric matrix for high-performance gas separation.

Developing solid-state polymer electrolytes (SPEs) with fast Li + transport and stable electrode interfaces is essential for high-performance lithium metal batteries. Herein, a protonated amino-functionalized metal-organic framework (pro-UiO66) is incorporated into a PEO-LiTFSI matrix to construct composite SPEs. Protonation introduces abundant TFSI − adsorption sites(-NH 3 + ), while the three-dimensional porous framework disrupts PEO crystallinity and provides angstrom-scale pathways for Li + migration. Various characterization confirms that pro-UiO66 maintains crystallinity and uniform dispersion in the polymer matrix. The optimized electrolyte containing 10 wt% pro-UiO66 exhibits reduced crystallinity (29.57%), a high Li + transference number (0.55), and an ionic conductivity of 4.65 × 10 −4 S cm −1 at 60 °C, together with an electrochemical stability window of 5.3 V. Li||Li symmetric cells cycle stably for over 3200 h, while LFP||Li cells deliver 142 mAh g −1 with 92.2% capacity retention after 300 cycles. Mechanistic analysis indicates that the synergistic effects of the porous framework and -NH 3 + functional groups promote LiTFSI dissociation, regulate Li + deposition, and enable the formation of a stable solid electrolyte interphase, thereby suppressing dendrite growth. This work provides insight into protonation-engineered MOFs fillers for designing SPEs toward safe and high-performance solid-state lithium metal batteries.

Self-targeted strategy: PAHs as precursors for PAH adsorbents. • Monomer selection and carbonization tune porosity (up to 1893 m 2 g −1 ). • CP-NAP-800 captures 49.87% of 16 PAHs from real FCC diesel. Polycyclic aromatic hydrocarbons (PAHs) in FCC diesel were employed as building blocks to construct hypercrosslinked polymers via Friedel–Crafts alkylation. KOH-activated carbonization yielded porous carbons with high surface areas (590–1893 m 2 ·g −1 ) and hierarchical microporosity. The optimized adsorbent, CP-NAP-800 (carbonized at 800 °C), exhibited exceptional adsorption for naphthalene (21.77 mg·g −1 ), anthracene (105.14 mg·g −1 ), and acenaphthylene (30.65 mg·g −1 ). Adsorption followed Langmuir and pseudo-second-order kinetics, indicating monolayer π–π stacking interactions with graphitized carbon. In real FCC diesel, CP-NAP-800 achieved a total capacity of 355.88 mg·g −1 for 16 priority PAHs with 49.87% removal efficiency, and maintained stable performance over six cycles. This work presents a novel self-targeted strategy for PAH capture and recovery, where the pollutants themselves serve as precursors, offering a sustainable remediation approach for the petrochemical industry.

Using Fermi resonance as a probe of the external field environment to reflect changes in hydrogen bonds. • It discusses the effects of π-hydrogen bonds in different directions on molecular vibrations and vibrational coupling. • A combination of experimental and computational methods was used to verify the differences in π-hydrogen bonds. In this study, the influence of π–hydrogen bonding (π-HB) on the Fermi Resonance (FR) of benzene in mixtures with methanol or dichloromethane was investigated using Raman spectroscopy combined with density functional theory (DFT) calculations, including reduced density gradient (RDG) analysis. The results reveal that the π-HBs formed in the two systems exhibit fundamentally different characteristics: axis-asymmetric π-HBs in the benzene–methanol system and axis-symmetric π-HBs in the benzene–dichloromethane system, leading to distinct FR behaviors. In the benzene–methanol system, the Fermi doublet shows a red shift with increasing benzene concentration, accompanied by an increase in the coupling constant W from 9.70 to 10.19 cm -1 , which is attributed to π-electron redistribution and a broadened vibrational potential induced by asymmetric π-HB formation. In contrast, the benzene–dichloromethane system exhibits a blue shift of the Fermi doublet with no significant change in W, resulting from axis-symmetric π-HB interactions that concentrate electron density without altering the coupling strength. These results demonstrate that FR can serve as a sensitive probe for distinguishing different types of intermolecular interactions in weakly interacting molecular systems.

Functionalized nanosilica is used to carry agrochemical IAA via disulfide bonds. • Under GSH environment, SiO 2 -S-S-IAA exhibits significant redox responsiveness. • The -SH on the surface of SiO 2 can form complexes with various heavy metal ions. • Dual-functional nanocarrier allows sustained IAA release and capture of metal ions. Owing to the low efficiency and lack of target specificity in the application of agrochemicals, e.g., plant growth regulators, the resulting environmental pollution and resource waste have raised enormous concerns over environments and human health. Herein, a redox-responsive nanosilica carrier (SiO 2 -S-S-IAA) was developed for efficient release of 3-indoleacetic acid (IAA), by functionalizing the surface of nanosilica with 3-mercaptopropyltrimethoxysilane (MPTMS), followed by the covalent coupling of IAA via redox-cleavable disulfide bonds. Under the high level of glutathione (GSH) in the plant microenvironment, IAA was released in a controlled way through disulfide bond cleavage, thus achieving redox response. In vitro controlled-release experiments confirmed that the release amount of IAA was significantly higher in the environment of 10 mM GSH, more than 10 folds at pH 5.5. Meanwhile, the thiol groups generated after release could form complexes with various heavy metal ions (Hg 2+ , As 3+ /As 5+ , Cd 2+ , Pb 2+ ), with the highest adsorption efficiency towards Hg 2 + up to 57.95%. More importantly, in planta experiments under cadmium stress have demonstrated that SiO 2 -S-S-IAA not only promoted rice seedling growth but also significantly reduced Cd 2+ accumulation in shoots, effectively inhibiting its transfer to edible parts. This work establishes a dual-functional nanocarrier platform that combines targeted agrochemical delivery with in situ heavy metal immobilization, offering a promising strategy for sustainable and precise crop protection.
