Strigolactones (SLs) are novel plant hormones that play crucial roles in regulating plant growth and development. The stereoisomers of SLs often exhibit distinct biological activities, making their chiral separation and analysis essential for understanding their regulatory roles in plant branching. This study focused on the chiral separation and characterization of SL stereoisomers, including GR24 (synthetic) and strigol (natural). A magnetic nanocomposite (Ni₃(HITP)₂@Fe₃O₄@rGO) was synthesized for SL extraction, combined with SFC-MS/MS for precise separation and quantification. The method exhibited excellent linearity (0.2–50 ng/mL), minimal matrix effects (1.64–2.17 %), and low detection limits (1.93–3.76 pg/mL). Recoveries ranged from 86.90 % to 106.37 % with RSDs of 2.56 %–13.54 %. Under nitrogen and phosphorus stress, only (+)-strigol was detected in the roots of Oryza sativa L., suggesting its regulatory role under stress conditions. This reliable method provides robust support for exploring the physiological roles of SL stereoisomers in plants, shedding light on their functions in stress response and development.

In the practical purification of oily wastewater, the application of polymer-based membrane is greatly restricted due to the oil adhesion and complicated fouling problems. Herein, to conquer the aforementioned challenges, we prepared the polyphenol mediated Photo-Fenton self-cleaning and superhydrophilic/underwater superoleophobic α-FeOOH/g-C 3 N 4 @PVDF composite membrane via simple vacuum-assisted self-assembly technology. The g-C 3 N 4 nanosheets modified by tannic acid were introduced into the surface of PVDF ultrafiltration membrane, in which the intercalation structure was regulated by the random interpenetration of α-FeOOH nanorods . The abundant hydroxyl and amino groups and the rough micro-nano structure formed by intercalation structure were favorable for the superhydrophilic feature (WCA = 0°, UOCA>150°), thus resulting in ultra-low oil adhesion. Specially, the intercalation structure improved the water permeation channel, further promoting the water/oil separation flux. Therefore, the composite membrane exhibited superior separation flux (452.35–650.21 L m −2 h −1 ) and separation efficiency (>99.06 %) for various surfactant-stabilized emulsions. Moreover, thanks to the Photo-Fenton reaction, the composite membrane showed excellent degradation efficiency on simulated pollutants (various dyes) within 60 min (MeB: 95.55 %, CR: 90.83 %, MO: 98.90 %, CV: 95.11 %), showing satisfactory photocatalytic self-cleaning performance. This work provides a strategy for the potential application of polymer-based membranes in the treatment of complex surfactant-stabilized emulsion wastewater from petrochemical industry.

This study describes the synthesis of a novel S-scheme heterojunction of ZnO/In 2 S 3 , with S−O covalent bonds , achieved through a hydrothermal method . The optimized heterojunction shows exceptional photocatalytic activity , achieving a H 2 generation rate of 2488 μmol g −1 h −1 and a degradation efficiency of 86 % for tetracycline hydrochloride (TCH) within 2 h. These values surpass those of In 2 S 3 alone by 35 and 1.4 times, respectively. Various techniques, including electron spin resonance, X-ray photoelectron spectroscopy, Kelvin probe force microscopy and density functional theory calculations confirm the S-scheme heterojunction. The establishment of a chemical S−O bond between In 2 S 3 and ZnO facilitates an atomic level interfacial pathway, enabling efficient transportation of interfacial electrons.

Hierarchical Y/SBA-15 meso-microporous composites (YS- x ) and corresponding highly dispersed catalysts (Ni/YS- x ) were prepared and applied to the production of jet fuel range hydrocarbons by the selective hydrogenation of oleic acid. Small particle size and electron-deficient Ni δ+ are detrimental to the C C bond activation of the η 1 (C)-acyl conformation and inhibit the decarbonylation/decarboxylation pathway. Besides, the activation ability of the C C bond is regulated to avoid excessive cleavage by the acidity and diffusion properties of the hierarchical Ni/YS- x catalysts, thus affecting their hydroisomerization and hydrocracking properties. The abundant acid sites are beneficial to the selective activation of the C O bond of the η 2 (C, O)-aldehyde conformation and the promotion of the reductive deoxygenation pathway. The optimal Ni/YS-1 shows the highest iso / n -alkane ratio ( i / n = 6.26) and superior jet fuel range hydrocarbons yield (48.8%, 340°C), which is a benefit from its outstanding acid–metal balance and worthy diffusion property.

To understand the characteristic aroma compounds and their changes during the processing of sauce-flavoured black pork (SBP), headspace solid phase microextraction gas chromatography-olfactometry mass spectrometry (HS-SPME-GC-O-MS) was used to determine the volatiles during processing. A total of 63 volatiles were detected during the whole processing, including aldehydes, alcohols, esters, and furans, etc. The aroma characteristics of SBP are meaty, fatty, fruity, and grassy. During the processing, the aroma characteristics gradually shift from grassy and fruity aromas to being dominated by meaty, supplemented by fruity, fatty, and grassy aromas. Further, the impact of 25 characteristic aroma compounds on aroma changes was visualized through co-occurrence network analysis. Specifically, esters showed increasing centrality (network connectivity) in later stages, indicating their dominant role in transitioning aroma from grassy and fruity to meaty dominance. Ten key characteristic aroma compounds of SBP were confirmed based on molecular sensory science methods: isovaleraldehyde, hexanal, phenylacetaldehyde, eucalyptol, linalool, ethyl butyrate, ethyl 2-methylbutyrate, ethyl isovalerate, ethyl hexanoate, and 2-pentylfuran. Esters are the most important contributor to the characteristic aroma of SBP, with significantly higher content (929.34 μg/kg) and aroma character impact (58 %) than aldehydes (662.35 μg/kg, 25 %).

The change of aroma fingerprint and its corresponding precursors during pork roasting remains unclear. The formation of key aroma compounds in roasted pork was determined through multidimensional mass spectrometry. The results indicated that the roasted pork exhibited pronounced roasty, fatty, meaty, sweet, and grassy notes. Thirty-nine key aroma compounds were identified, such as 2-ethyl-3,5-dimethylpyrazine, ( E, E )-2,4-nonadienal, and 1-octen-3-ol. Particularly, the pyrazines and unsaturated aldehydes were key contributors to the roasty and fatty aromas, respectively. The linoleic acid and oleic acid served as critical precursors for the generation of carbonyls and alcohols. The glucose, arginine, glycine, and alanine were essential precursors for the formation of pyrazines. Notably, the 1-octen-3-ol emerged as a key marker discriminating different roasting durations. The structural unfolding of proteins facilitated both the generation and retention of key odorants. These findings provided new insight for targeted regulation and quality control of aroma development in roasted meat products.

Cocoa aroma is a pleasant and highly market-accepted aroma type in white tea, yet its underlying key aroma components remain unclear. In this study, sensory quantitative descriptive analysis (QDA), gas chromatography–mass spectrometry (GC–MS), gas chromatography-olfactometry (GC-O), molecular docking , and aroma addition tests were employed to elucidate the aroma characteristics and aroma profile of cocoa aroma white tea (CCWT), traditional white tea (WT) and cocoa beans (CC), and then construct a comprehensive aroma flavor wheel. It was observed that CCWT consists of a composite aroma dominated by Cocoa aroma, accompanied by flowery, sweet, and herbal aroma. Ten compounds were identified as key aroma constituents in CCWT, including linalool , nerol , and β-ionone. Notably, isovaleraldehyde , 2-methylbutyraldehyde, and phenylacetaldehyde were identified as the primary aroma components contributing to the cocoa aroma. Molecular docking results revealed that 3 key aroma components generate cocoa aroma through hydrogen bonding and hydrophobic interactions with olfactory receptors , with binding energies of less than −4 kcal/mol. The addition tests indicated that isovaleraldehyde and 2-methylbutyraldehyde primarily contribute to the cocoa aroma in CCWT, while phenylacetaldehyde likely enhances this aroma through synergistic effects with other compounds. This research provides essential scientific support for enhancing white tea quality and guiding product development. A solid foundation has been established to facilitate sustainable growth of the broader tea industry.

Electrochemical catalytic water splitting is considered as a promising technique for green hydrogen production, and highly active catalysts toward cathodic hydrogen evolution reaction (HER) and anodic oxygen evolution reaction (OER) are required, especially bifunctional ones. In this work, the bifunctional catalysts with Co-CoO x @N, O co-doped carbon (NOC) hybrid nanostructures have been prepared via pyrolysis of ZIF-Co with assistance of a small amount of KNO 3 . KNO 3 plays important roles in tuning the inner and the outer structures of Co-CoO x @NOC hybrid nanostructures. The proposed S Ov , which is defined as the content of oxygen vacancy (O v ) per unit surface area of the inner Co-CoO x nanoparticle, and charge transfer resistance ( R ct ) are used as the descriptors of the inner structures, while hydrophilicity (or contact angle) is applied as the main feature of the outer structures. S Ov , R ct and hydrophilicity are well tuned by the fed mass of KNO 3 , and a moderate fed mass is the key to balancing S Ov , R ct and hydrophilicity and further is beneficial to accelerating specific and intrinsic activity for both HER and OER . Thus, the bifunctional HER/OER specific and intrinsic activity is peaked by Co-CoO x @NOC-0.025KNO 3 with a moderate fed mass of KNO 3 of 0.025 g, such as j s-250-HER of 539.22 μA cm -2 BET and j s-350-OER of 129.83 μA cm -2 BET at the HER and OER overpotentials of 250 and 350 mV, respectively, also corresponding to high turnover frequencies of 6.653 and 0.801 s −1 , respectively. The optimal catalyst also has high apparent activity, such as achieving high HER and OER current densities of 500 mA cm −2 , only requiring low overpotentials of 273.1 and 382 mV, respectively. It promotes overall water splitting with a high current density of 500 mA cm −2 at a cell voltage of ∼ 1.63 V, showing the high HER and OER Faradaic efficiencies of ∼ 98.2 and ∼ 98.0 %, respectively.

Environmentally toxic organic pollutants, namely methylene blue (MB), neutral red (NR), Rhodamine B (RhB), and methyl orange (MO) dyes contain highly toxic, carcinogenic, non-biodegradable, and colored pigments which cause harm for humans and aquatic organisms even at low concentrations. To detoxify these toxic organic pollutants from the wastewater, the bimetallic solid solution-typed In–Mo(O,S) 2 catalyst with various indium (In) contents were synthesized at low temperature through a simple precipitation method. The morphological, structural, chemical compositions, electrochemical and optical properties of the catalysts were thoroughly characterized. The photodegradation performance of the In–Mo(O,S) 2 catalysts over the cationic, anionic and neutral dyes were studied under visible light irradiation. It has been observed that the photocatalytic activity was enhanced as In was added to the Mo(O,S) 2 catalyst, and In–Mo(O,S) 2 -20 was found to be the best composition to completely degrade four organic dyes. The dye degradation had rate constant values of 9.5 × 10 −2 min −1 , 6.3 × 10 −2 min −1 , 4.4 × 10 −2 min −1 , and 15.7 × 10 −1 min −1 for MB (20 ppm), NR (20 ppm), RhB (10 ppm), and MO (10 ppm) dyes, respectively. The active species for degradation of MB is different from those for RhB and MO. Single phase In–Mo(O,S) 2 -20 capable to degrade four kinds of dyes at a fast rate is a good photocatalyst.

Oroxylin A (OA), as a natural flavonoid extracted from the root of Scutellaria baicalensis Georgi, is a candidate drug with multiple pharmacological activities . However, pharmacokinetic studies of OA have rarely been reported up to now. The present study aim to conduct a systemic evaluation on the pharmacokinetics, tissue distribution and excretion of OA in rats, with quantification of both OA and its two metabolites, Oroxylin A 7-O-glucuronide (OG) and Oroxylin A sodium sulfonate (OS) by the sensitive and rapid UPLC-MS/MS methods. The results show that OA was rapidly eliminated in vivo after a single–dose (2 mg/kg) i.v. administration of OA. The relative bioavailability of OA in all three i.g. administration groups (40, 120, and 360 mg/kg) were <2%. The AUC 0−t values of OA, OG, and OS in rats show an apparent dose-proportionality. OA, OG, and OS all underwent a rapid and widespread tissue distribution after i.g. administration (120 mg/kg) of OA. Except for stomach and intestine, the major distribution tissues of OA and its two metabolites in rats were liver, kidney, respectively. And OA was more widely distributed in tissue than its metabolites. After i.g. administration (120 mg/kg) of OA, it was mainly excreted from the feces, and OG mainly excreted from bile and urine, while OS almost free of excretion. This work present a comprehensive pharmacokinetics information for further investigation of OA and its two metabolites.

Malvacin-3- O -galactoside (M3G) is the most abundant anthocyanins component in blueberries and has high biological activity. We investigated the effect of a pulsed electric field (PEF) on the interaction between whey protein (WP) and M3G. Stability experiments showed that PEF significantly improved stability of the anthocyanin-whey protein complex (M3G-WP), particularly at 15 kV/cm for 30 min. PEF-treated M3G-WP (PEF-M3G-WP) was used as a model of silica-induced lung fibrosis to investigate its anti-inflammatory activity and molecular mechanisms. Both in vivo and in vitro experiments demonstrated that PEF-M3G-WP alleviated inflammation in macrophages. It upregulated the expression of PINK1 and Parkin and downregulated the expression of NLRP3, CASP1, and GSDMD NT. Furthermore, qPCR experiments showed that PEF-M3G-WP inhibited the release of inflammatory factors IL1b and IL18 by upregulating Atg5 and downregulating P62 in alveolar macrophage cell lines (MH-S). In summary, PEF-treated M3G-WP may be a potential method for alleviating pulmonary fibrosis.

Microplastics sorption of persistent organic pollutants (POPs) was the core processes that cause negative effects to biota, and their influencing factors and related mechanisms are poorly understood. In this study, we explored the impacts of water extractable organic matter (WEOM), an important source of endogenous dissolved organic matter in mangrove sediment, on the sorption coefficients of typical parent, alkyl and N/O/S-containing polycyclic aromatic hydrocarbons (PAHs) by microplastics. The presence of L-WEOM (D) impeded the PAHs sorption as the coefficients ( K f ) decreased to 10.17 (μg/kg)/(μg/L) n and to 8.39 (μg/kg)/(μg/L) n for fluorene (Flu) and 1-methyl-fluorene (1-M-Flu), respectively. The K f exhibited good linear relationships with the aliphaticity of L-WEOM ( p < 0.05) rather than the aromatic carbon/alkyl carbon content ( p > 0.05). Under the presences of L-WEOM (D), (S) and (K), the lone pair electrons of N/O/S-containing PAHs was the dominant factor contributing to the obvious difference of the K f values from the other groups. Moreover, the largest impact of L-WEOM (D) on the Flu sorption was in the case of PVC microplastics, while almost no effect was in the case of PS microplastics. The findings of our work may be helpful in improving our understanding of the role of WEOM on the sorption of PAHs to microplastics in the field mangrove sediment.
