The halophyte Suaeda maritima subsp. salsa (L.) Soó has been utilised as a traditional medicinal herb in China. Its phytochemical profile remains inadequately elucidated to date. In this study, twelve compounds, including one previously undescribed biflavonoid, 3′-methoxy-4′,4′″,5,5″-tetrahydroxy-[C7-O-C7″]-biflavone (1), and eleven known compounds (2∼12), were isolated from the whole plant of S. salsa. Their structures were fully determined via NMR, MS data analysis and literature comparison. The anti-microbial assay revealed that compounds 1, 9, and 12 exhibited an inhibitory effect against P. aeruginosa with an MIC of 25 μg/mL. Additionally, compounds 3, 5, 7, 9 and 12 displayed potent inhibitory activity against the growth of E. coli, with their MIC values ranging from 12.5 to 25 μg/mL. Furthermore, compound 1 showed the cytotoxic activity against human SGC-7901 cells with an IC50 of 89.04 ± 0.26 μm. Biflavonoid 1 represents the first reported occurrence of this class of compounds within the genus Suaeda.

The photocatalytic coupling of selective phenylcarbinol oxidation with hydrogen evolution has attracted considerable attention as a promising dual-functional reaction system. Herein, a lattice-matched 2D/3D NiS/CdIn 2 S 4 (NiS/CIS) Schottky heterojunction is rationally designed for efficient dual-functional photocatalysis under visible light. Structural analyses confirm the uniform deposition of NiS nanosheets on octahedral CIS with a lattice mismatch below 5%, ensuring coherent interfacial contact. The optimal 3% NiS/CIS composite exhibits exceptional hydrogen and benzaldehyde production rates of 2636.4 and 2717.6 μmol g −1 h −1 , respectively—representing enhancements of 39.7 and 38.0 times over pristine CIS. The catalyst also demonstrates remarkable stability, retaining over >99.0% activity after six cycles. Mechanistic studies reveal that the Schottky junction facilitates spatial separation of photogenerated carriers: electrons migrate to NiS, prolonging charge carrier lifetimes and lowering the hydrogen evolution overpotential, while holes accumulate on CIS that facilitated phenylcarbinol adsorption to drive selective phenylcarbinol oxidation via a carbon-radical pathway. This work provides a viable approach for designing efficient bifunctional photocatalysts through lattice-matched interface engineering.

Fuji apples from the Aksu production region are highly favored by consumers. In contrast, those from the Yili region exhibit marked differences in flavor profiles, the mechanisms of which remain unclear. This study investigated the flavor variations in Fuji apples from these two producing regions by integrating analyses of both volatile and non-volatile metabolites. The results from the electronic nose and electronic tongue indicated that the sensors for W1W, W2W, W5S, and sourness exhibited the most pronounced responses in Fuji apples from the Aksu region. 16 key aroma-active compounds and 143 non-volatile differential compounds were identified. The aroma of Fuji apples was predominantly characterized by esters and terpenoids, with representative compounds including hexyl 2-methylbutanoate, 3-Methylbutyl acetate, 2-Methylbutyl acetate, and citronellol. These compounds collectively impart fruity, sweet, and floral notes. Furthermore, the peel of the ‘Yanfu 6’ cultivar from Aksu exhibited distinctive rosy and woody notes, while its pulp possessed a pineapple-like aroma. KEGG pathway enrichment analysis demonstrated that amino acid metabolism, fatty acid metabolism, and phenylalanine metabolism are interconnected. This study provides valuable insights for systematically understanding the formation of characteristic aromas in Fuji apples from the Xinjiang region

Acute kidney injury (AKI) is a common and serious clinical syndrome, and currently there is a significant lack of effective pharmacotherapy. Pinocembrin (PIN), a flavonoid derived from propolis, possesses antioxidant properties and could be advantageous in treating AKI. However, its poor water solubility limits its clinical application. Lipid nanoparticles have become a promising drug delivery method due to their excellent biocompatibility and capacity to improve drug targeting. In this study, sialic acid (SA) - modified PIN liposomes (PIN-LIP) were developed for targeted protection against AKI. The PIN-LIP effectively targeted the kidneys via the specific interaction between SA with E-selectin. Importantly, in vivo experiments in two AKI models (cisplatin-induced and rhabdomyolysis-induced AKI) confirmed that the injected PIN-LIP was retained in the injured kidneys for more than 24 h. The PIN-LIP exhibited excellent antioxidative and antiapoptotic effects on HK-2 cell injury induced by H2O2 in vitro. It also improved renal function and reduced oxidative stress, tubular cell apoptosis and inflammatory responses in in vivo AKI models. In addition, PIN-LIP showed a favorable biocompatibility and safety profile in vivo. Therefore, PIN-LIP may be a promising therapeutic option for AKI treatment.

With the widespread use of electronic devices, electromagnetic radiation pollution has become increasingly severe, posing potential threats to human health and the ecological environment. This study successfully prepared a tough, adhesive, green, and multifunctional semi-interpenetrating network organic hydrogel using a three-step method, and enhanced its electromagnetic shielding performance by incorporating CNTs@ZIF-67 composite nanoparticles. An environmentally friendly semi-interpenetrating network organic hydrogel was constructed using polyvinyl alcohol (PVA) and bio-based gelatin (Gel). Through an in-situ growth method, ZIF-67 was grown on the surface of carbon nanotubes (CNTs) to prepare CNTs@ZIF-67 composite nanoparticles. Using a one-pot approach, these composite nanoparticles were dispersed in a precursor solution containing gelatin and polyvinyl alcohol, followed by cyclic freeze-thaw processing to fabricate a novel hydrogel material that combines high toughness with outstanding electromagnetic shielding performance. When incorporating 50 mg of CNTs@ZIF-67, the organic hydrogel achieves a conductivity of 0.512±0.026 S/m, a compressive modulus of 41.8±2.09 kPa, a compressive deformation rate of 66.33±3.01%, a moisture content of 88.99±0.89%, and a water absorption rate of 265.92±1.33%. The PGZC1 organic hydrogel with a thickness of 3 mm exhibits an average electromagnetic interference shielding effectiveness (EMI SE) of 33.32±1.67 dB within the X-band (8.2–12.4 GHz), thus providing an innovative material solution for mitigating electromagnetic wave pollution.

We developed an enzyme-cascade-amplified whole-cell biosensor for sub-nanomolar methylmercury (MeHg) detection in environmental waters. By integrating a MerB-based organomercurial lyase with a water-soluble indigoidine reporter system in a decoupled genetic circuit, we achieved a limit of detection (LOD) of 0.04 nM and a linear range of 0.02–1.22 nM. Systematic comparison of intracellular versus surface-displayed MerB strategies revealed that intracellular expression (TOP10/pCon-IND-C-B) provided superior sensitivity. The biosensor demonstrated robust performance across tap water, surface water, and seawater matrices (R2 > 0.98) with negligible matrix effects, enabling direct colorimetric quantification of culture supernatants. Notably, metabolic burden from pigment synthesis dominated the dose-response profile rather than MeHg cytotoxicity. This biosensor offers a cost-effective alternative for screening MeHg in environmental water, with detection limits that far exceed WHO drinking water guidelines and a potential for high-throughput environmental monitoring.

Nonlinear optical (NLO) and birefringent crystals are pivotal for advancing photonic technologies, enabling critical functions from laser frequency conversion to quantum information processing. To address the pressing need for miniaturized devices with enhanced optical anisotropy, we strategically select 5-hydroxy-2-pyridinecarboxylic acid (C 6 H 5 NO 3 ), a low-toxicity, cost-effective organic molecule featuring a pyridine-derived π -conjugated system marginally expanded beyond benzene, as NLO functional motif. This molecular design incorporates dual-functional OH/COOH groups that synergistically extend π -delocalization within the planar six-membered ring and provide two anionic states ([C 6 H 4 NO 3 ] − and [C 6 H 3 NO 3 ] 2− ), facilitating diverse supramolecular assemblies with alkali/alkalineearth metal ions. Through confined assembly optimization, we discovered a crystal Na 2 (C 6 H 3 NO 3 )·H 2 O, which achieves an excellent ultraviolet (UV) NLO performance: phase-matched second harmonic generation (SHG) intensity (14.0 × KH 2 PO 4 (KDP) at 1064 nm, the highest among planar mono-six-membered-ring systems), giant birefringence (0.487 at 546 nm), and a UV cutoff edge (321 nm). Multimodal analyses confirm the planar organic anion [C 6 H 3 NO 3 ] 2− as the origin of these exceptional optical responses, where ionic bonding and N–O/N layer confinement enforce optimal alignment.

Sesame oil is one of the most popular sesame products for consumers. Roasting is a commonly employed heat treatment method in sesame oil processing. This work aims to investigate the effects of roasting temperature and time on sensory profiles, volatile components, fatty acid composition, and oxidative stability of the oil. Quantitative descriptive sensory analysis was employed to reveal changes in aroma characteristics of sesame oils from different roasting conditions. Volatile compounds of the oils were analyzed via headspace solid-phase microextraction/gas chromatography–mass spectrometry (HS-SPME/GC-MS), identifying 56 components, including 30 key aroma-active compounds (odor activity value, OAV ≥ 1) across 18 samples. Principal component analysis (PCA) was performed to explore the effect of roasting conditions on volatiles of sesame oils. The oxidative stability of the oils was also determined by RapidOxy reactor. The results demonstrated that the effect of roasting time on the flavor of sesame oil was greater than that of temperature. Moreover, the effect of roasting conditions (temperature/time) on the fatty acid profile of sesame oil was not significant. This provided some theoretical foundation and data support for improving the processing technology of sesame oil and controlling its flavor quality.

This work introduces an innovative stacked iron mesh electrode configuration to achieve accelerated degradation of perfluorooctanoic acid (PFOA) by synergistically coupling electrochemical oxidation with peroxymonosulfate (PMS) activation. The system was systematically evaluated through electrochemical measurements, free radical quenching, and electron paramagnetic resonance spectroscopy, complemented by density functional theory calculations. The optimized triple-layer Fe electrode demonstrated outstanding performance, attaining nearly complete PFOA removal (100 %) within 12 min and a high kinetic rate constant of 0.218 min –1 . DFT analysis revealed that the Fe mesh possessed the strongest PMS adsorption energy (–2.68 eV) and the shortest Fe–O bond length (2.24 Å), confirming its superior activation capability. Mechanistic studies confirm the effectiveness of the electron transfer coupled with the hydroxyl radicals in defluorination and decarbonization during PFOA degradation. In addition, the system exhibited high cycle stability and strong tolerance to various background ion under continuous operations in the amplification experiment. The system also exhibited superior performance and low leaching of metal ions in treating various organic pollutants of practical wastewater (fluoride wastewater and landfill leachate). These findings present an effective and practical strategy for the remediation of persistent per- and polyfluoroalkyl substances in contaminated water sources.

The increasing release of antimony (Sb) into water environments due to anthropogenic activities poses significant ecological risks. This study developed a novel hybrid material, zeolitic imidazolate framework-8-iron nanoparticles (ZIF-8-Fe NPs), which demonstrates a synergistic adsorption-oxidation mechanism for efficient removal of Sb(III) from aqueous solutions. Major findings reveal that at an initial Sb(III) concentration of 1 mg L-1, ZIF-8-Fe NPs achieved a 73.3% removal efficiency within three hours through the dual processes of direct adsorption and oxidation of Sb(III) to Sb(V). Scanning electron microscopy-energy dispersive spectrometry (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) revealed that the removal mechanism involved both direct adsorption of Sb(III) by ZIF-8-Fe NPs and oxidation of Sb(III) to Sb(V), with two distinct morphologies of Sb adsorbed on the surface. The formation of covalent bonds (Zn-OH-Sb and Fe-O-Sb) was identified as the key factor in removing both Sb(III) and Sb(V) from aqueous solutions. The adsorption process conformed to the Langmuir adsorption isotherm and pseudo-second-order kinetics, with correlation coefficients (R²) of 0.959 and 0.999, respectively. The proposed mechanism suggests that the formation of Zn-OH-Sb and Fe-O-Sb covalent bonds plays a crucial role in Sb(III) removal. Significantly, ZIF-8-Fe NPs achieved removal efficiencies of 91.5% and 94.8% for Sb(III) at environmentally relevant concentrations of 100 µg L-1 and 20 µg L-1, in actual mining wastewater, demonstrating its practical applicability. This study establishes that ZIF-8-Fe NPs constitute an effective nanomaterial with significant potential for Sb(III) remediation in wastewater.

Self-powered electrochromic devices, which integrate optical modulation with energy storage, represent a significant direction in adaptive optics and smart electronics. However, they still face limitations such as monotonous operation modes, slow self-charging, and complex fabrication processes. To address these challenges, we present a novel self-powered electrochromic system (MnO 2 ||PEDOT:PSS/PANI:PSS||Zn) based on a synergistic strategy of complementary color fusion and potential gradient utilization. The electrochromic electrode exploits the complementary color fusion effect between the cathodic electrochromic material PEDOT:PSS and the anodic electrochromic material PANI:PSS, enabling distinct color manifestations (green, purple, and blue) at different redox states. The inherent potential gradient among MnO 2 , PEDOT:PSS/PANI:PSS, and Zn provides a robust driving force for the redox reactions in the electrochromic electrode, allowing the system to achieve rapid and reversible bidirectional color switching along with multiple output modes. Via a fully-printed fabrication process, we integrated the three electrodes onto a single paper substrate, constructing a compact, mechanically flexible, multi-mode self-powered electrochromic system. This system has been successfully applied in reconfigurable multicolor display arrays and pressure-activated connected smart display labels. We envision that this work provides new insights into the development of flexible, multifunctional energy-optical systems.

Oxygen vacancies (O v ) on metal oxide surfaces exhibit high catalytic activity for activating peroxymonosulfate (PMS) in wastewater decontamination, yet their in-situ regeneration remains a significant challenge. This study successfully achieves in-situ real-time regeneration of O v on CuO surfaces through simple alkali etching without interrupting the contaminant removal process. The surface hydroxyl groups introduced by alkali treatment significantly reduce the formation energy of O v on CuO surfaces from 1.60 eV to 0.38 eV. Both experimental results and density functional theory calculations reveal that the high activity of CuO relies on the synergy of surface hydroxyl groups and O v . This synergy increases the antibonding states below the Fermi level and the electron spin density of Cu near O v , thereby promoting electron transfer from CuO to PMS. As a result, by just adding an equimolar amount of alkali relative to PMS in CuO/PMS system, the degradation rate constant of sulfamethoxazole (SMX) greatly increases by 42 times. The primary reactive oxygen species in this system are sulfate radicals and hydroxyl radicals. Furthermore, OH - /CuO/PMS system exhibits a long-term stability (> 300 h) for SMX removal in a real water matrix. This work provides a highly executable method to in-situ real-time regenerate O v on CuO surfaces, representing significant progress in the critical yet underappreciated field of catalyst regeneration.
