The presence of metronidazole (MNZ) in medical wastewater poses a potential threat to environmental safety and people's health. Herein, we report an innovative strategy to fabricate a recyclable bayberry tannin (BT)-functionalized melamine foam (MF)-supported nanoscale zero-valent iron (MFBT-Fe 0 ) catalyst for efficient MNZ degradation in medical wastewater. The through-pore structure of MF reduced mass transfer resistance in heterogeneous systems, while the amphiphilic BT stabilized nZVI via steric hindrance and chelating interactions and created a high-concentration MNZ microenvironment through hydrophobic combined with hydrogen bonding. The synergistic design overcame the long-standing challenges of mass transfer limitations in heterogeneous systems, nZVI aggregation- and shedding-mediated activity degradation, and the establishment of high-concentration microenvironments for MNZ reductive transformation. Consequently, the highly accessible nZVI catalyst, MFBT-Fe 0 , rapidly removed MNZ, achieving a 96.4 ± 0.82 % removal rate within 90 min, with a degradation capability 2.9-fold higher than the non-BT-functionalized MF-Fe 0 . MFBT-Fe 0 exhibited exceptional cycle stability, maintaining an MNZ removal rate of up to 80 % after 6th cycles. Mechanistic studies revealed contributions from surface complexation, hydrogen bonding, and π-π stacking, with HPLC-MS confirming degradation pathways of nitro reduction, denitrification and hydroxyethyl cleavage. This work provides a sustainable, high-performance catalyst for practical MNZ removal, addressing both efficiency and recyclability challenges in medical wastewater treatment.

The copigmentation effects of three phenolic acids (ferulic acid, sinapic acid, and syringic acid) on the color and thermal stability of Chinese bayberry anthocyanins were investigated. The three copigments of ferulic acid, sinapic acid, and syringic acid were found to have significant effects on the color enhancement of bayberry anthocyanins ( p < .05). The maximum absorption wavelength of the anthocyanin aqueous solution exhibited a bathochromic shift, L * decreased, and a * increased with the increase in the molar ratio of copigments. The thermal stability of bayberry anthocyanins was significantly improved after copigmentation. No new anthocyanin derivatives appeared after copigmentation. The thermodynamic parameters (Δ G , Δ H , Δ S ) of the three processes were all negative, indicating the three copigmentations were generally spontaneous and exothermic. The equilibrium constant ( K ) of the sinapic acid group was the greatest among the three phenolic acids, indicating that sinapic acid was more effective in stabilizing the anthocyanins.

Multifunctional coatings with broadband antireflective, durable, photocatalytic , and self-cleaning properties can enhance photovoltaic (PV) power generation by reducing the cleaning frequency and surface light reflection of PV modules . However, such coatings must be cost-effective and maintain their functional integrity under harsh outdoor environmental conditions. In this study, bayberry-like SiO 2 @TiO 2 nanoparticles were prepared by a sol–gel method, and their synthesis procedure and SiO 2 /TiO 2 sol volume ratio were optimized based on the refractive index , transmittance distribution, and methylene blue degradation rate . Afterwards, three-layer gradient refractive index broadband antireflective coatings (TGBA) of the optimized SiO 2 @TiO 2 nanoparticles were simulated theoretically and systematically characterized by various experimental techniques. The average transmittance of TGBA-coated glass was 8.93% (380–1800 nm) higher than that of undipped glass, and the photocatalytic performance of TGBA was verified by studying methylene blue photodegradation . The self-cleaning performance of TGBA was assessed by outdoor exposure, multi-cycle ultraviolet (UV) irradiation, and dark storage. The durability of TGBA was evaluated by conducting hardness measurements , abrasion testing, thermal cycling, and damp heat tests . The external quantum efficiency and J–V curves of TGBA-coated PV mini-modules revealed that their short-circuit current densities and power conversion efficiencies were substantially higher than those of undipped modules. The proposed multifunctional coatings can enhance PV power generation in harsh environments.

Ethylene is an essential indicator of fruit ripening and climacteric or non-climacteric nature. This study investigated the postharvest behavior of five Chinese bayberry cultivars ‘Biqi’, ‘Dongkui’, ‘Fenhong’, ‘Xiazhihong’, and ‘Shuijing’. The fruits were harvested mature and stored at room temperature (25 °C) and under cold storage conditions (4 °C) to investigate the dynamics of ethylene production, firmness, anthocyanin content, and cell wall polysaccharide composition, as well as basic fruit physicochemical characteristics. The results show that Chinese bayberry is a climacteric fruit with ethylene production peaking shortly after harvest, especially at room temperature. Fruit color intensified over time due to anthocyanin accumulation, particularly in the flesh core. Darker cultivars produced more ethylene, which correlated with higher anthocyanin levels. At room temperature, ‘Biqi’ (black) had the highest ethylene production (4.03 µL·kg−1·h−1) and anthocyanin content (0.91 mg/g FW), while ‘Shuijing’, the white cultivar, had the lowest ethylene levels (1.9 µL·kg−1·h−1) and anthocyanin content (0.03 mg/g FW). Firmness significantly decreased at room temperature due to the degradation of hemicellulose and insoluble pectin, whereas cold storage mitigates this effect. After 3 days at room temperature, the average of firmness decreased by 23.7% in the five cultivars, compared to 12.7% under cold storage. Total soluble solids increase during storage, enhancing sweetness, especially at room temperature, with ‘Biqi’ increasing from 9.2 to 10.9% at 4 °C. Titratable acidity slightly decreased over time: the value for ‘Biqi’ decreased from 1.2% to 0.95% at room temperature and 1.1% at 4 °C. Citric, malic, and tartaric acid generally declined at room temperature but stabilized under cold storage. Sucrose, fructose, and glucose increased or remained stable, with significant varietal differences. Our results indicate that storing Chinese bayberry at 4 °C effectively preserves its quality and extends postharvest life. These findings underscore ethylene’s key role in regulating ripening, postharvest quality, and shelf life by influencing fruit color, firmness, and overall consumer appeal.

Fruits tend to possess different nutritional values among different cultivars of same family. Therefore, in this study, the composition and antioxidant activity of some new and common bayberry cultivars were evaluated. Significant amounts of phenolics (0.47 to 2.31 g gallic acid equivalents/kg), flavonoids (0.34 to 2.08 g rutin equivalents/kg) and procyanidins (0.24 to 1.99 g catechin equivalents/kg) were found in all tested bayberry varieties. Anthocyanin cyanidin-3-glucoside and flavonol myricetin was detected in almost all cultivars, however, cyanidin-3-glucoside was not detected in new cultivar Xishanbai. Antioxidant activity of bayberry was highly correlated with contents of phenolics, including flavonoids. However, no positive correlation was observed between cellular reactive oxygen species scavenging ability and bioactive compounds. The new cultivar Yingsi was found to have higher levels of nutritional components and potent antioxidant activity among all tested cultivars.

Biorefineries of polyphenols from plant leaves maximize their commercial value for developing biomedicines and nutrients. However, condensed tannins (CTs) constitute extensive polyphenols from plant leaves, which hinders the maximization due to extremely low bioavailability. Therefore, a simple, and sustainable one-step method was established to simultaneously extract polyphenols and depolymerize CTs with only endogenous flavan-3-ols from Chinese bayberry leaves via acid catalysis, which markedly improved the bioavailability of total polyphenols. Afterward, purification of polyphenols from depolymerized extract was studied with specific polymeric resins. Silica C18 showed the highest absorption efficiency of total polyphenols, while Amberlite XAD-7 and XAD-2 presented high selectivity toward polyphenols with high and low molecular weight, respectively. Combined depolymerization of CTs and purification with Amberlite XAD-2 showed the highest bioavailability and cellular free-radical scavenging activity of total polyphenols, which proved to be an ideal methodology for improving the bioavailability and activity of polyphenols from plant leaves.

Bayberry lacks a fruit skin covering and is prone to microbial contamination after harvest. Related products, such as Bayberry juice, can also be affected. Cold plasma (CP) shows promising antimicrobial applications in fruit juice, but its antimicrobial efficacy and underlying mechanisms against yeast remain inadequately explored. Therefore, this study aimed to elucidate the antimicrobial activity of CP against Kazachstania bulderi in bayberry juice, investigate its mechanisms through transcriptomic analysis. Results revealed that CP exhibited excellent antibacterial efficacy. Flow cytometry and transmission electron microscopy showed that CP caused wrinkling of yeast cell membranes and walls, mechanical damage to organelles and leakage of cellular contents. Transcriptomic sequencing identified a total of 1200 differentially expressed genes, primarily involved in amino acid synthesis, ribosome function, DNA repair, cell membrane and cell wall biosynthesis, and central carbon metabolism pathways. These changes indicated that CP induced cell membrane rupture and content efflux, leading to disruption of intracellular metabolic homeostasis, and that these damages induced the yeast itself to respond to CP stress through a series of stress responses such as the synthesis of amino acids and proteins and DNA repair. Regarding potential effects on juice nutrition and flavor, experimental results indicated that treatment had no significant impact on total phenols, total soluble solids, ascorbic acid, polyphenol oxidase, reducing sugars, total acidity, color, and key aroma components of bayberry juice. Additionally, CP alleviated the decline in total antioxidant capacity and total phenol content during juice storage, as well as the degradation of anthocyanins. This study suggests that cold plasma may be a promising method for juice sterilization and provides new insights into the inactivate mechanisms of cold plasma on yeast.

Chinese bayberry ( Morella rubra Lour ) is a fruit from the Myricaceae family, rich in various dietary nutrients, and has a long history of cultivation and use in both food and medicine. The diversity of Chinese bayberry resources and its perishable nature limit its reprocessing and long-distance sales, posing challenges for the industry. This study compared the decay resistance characteristics, soluble solids, organic acids, and apparent traits of six different Chinese bayberry resources in Hunan Province, evaluating their edibility and processing characteristics. Using LC-MS and GC–MS, the non-volatile and volatile components of the six types of Chinese bayberry were extensively identified. The results showed that different types of Chinese bayberry contain distinct metabolites, which are significantly correlated with their decay resistance and apparent traits. Compounds such as Mesuagin, Arctigenin, and Eugenin were directly related to the decay area ratio and fruit weight. Licoricidin and Naringenin may have potential relationships with decay resistance. In this study, we took bayberry from six different resources as an example and preliminarily demonstrated that there were significant differences in the decay resistance and apparent traits of different bayberry varieties, which were related to their internal metabolites. Several specific substances in bayberry that are directly related to the preservation and reprocessing characteristics of bayberry were identified. These substances may have the potential to become key potential markers for evaluating the processing and storage characteristics of bayberry.

Bayberry tannin (BT), a natural plant polyphenol, was used as a stabilizer to prepare supported platinum catalysts. Bayberry tannin was first grafted onto aminated SiO 2 beads and subsequently coordinate with Pt(IV) species. Then a series of heterogeneous Pt–bayberry tannin–SiO 2 (Pt–BT–SiO 2 ) catalysts was obtained after reduction with NaBH 4 . The catalysts were characterized by UV–DR, XRD and TEM, and the coordination state of Pt(IV) with BT grafted on SiO 2 beads was investigated by XPS. It was found that the Pt–BT–SiO 2 catalysts were highly active and stable in aqueous hydrogenation of acrylic acid, α-methacrylic acid, allyl alcohol and 2-methyl-3-buten-2-ol. Moreover, the Pt–BT–SiO 2 catalysts could be conveniently recovered from the reaction systems simply by filtration, and be reused at least five times without loss of activity.

The extraction of uranium(VI) from seawater is of paramount interest to meet the rapid expansion of global energy needs. A novel gelatin/PVA composite nanofiber band loaded with bayberry tannin (GPNB-BT) was used to extract uranium(VI) from simulated seawater in this study. It was fabricated by electrostatic spinning and crosslinking, and characterized by SEM, EDX, FTIR, and XPS. Batch experiments were carried out to investigate the adsorption of uranium(VI) onto GPNB-BT. Simultaneously, the regeneration–reuse process of the GPNB-BT was determined and illustrated here. The GPNB-BT exhibited excellent adsorption and regeneration performance, and a maximum adsorption capacity of 254.8 mg g−1 toward uranium(VI) was obtained at 298.15 K, pH = 5.5. Further, the regeneration rate for uranium did not decrease significantly after five cycles. Moreover, even at an extremely low initial concentration of 3 μg L−1 in the simulated seawater for 24 h, GPNB-BT showed an ultrahigh adsorption rate of more than 90% and adsorption capacity of 7.2 μg g−1 for uranium. The high density of adjacent phenolic hydroxyl groups and the specific surface area of GPNB-BT improved the adsorption ability of GPNB-BT for uranium. Therefore, the GPNB-BT was shown to have an application prospect for the effective extraction of uranium(VI) from seawater.

A superhydrophilic film without UV irradiation consisting of bayberry-like mesoporous TiO2 microspheres was prepared via a simple hydrothermal method combined with the spin-coating method. The crystal structure and surface morphology of the mesoporous TiO2 microspheres could be adjusted by controlling the reaction kinetics of hydrolysis and condensation of titanium tetrachloride in water/urea aqueous mixtures. The results showed that the surface morphology of TiO2 changed from “papilla-like”, “rough” to “smooth” and the crystal structure also changed from rutile to anatase when the amount of urea used ranged from 0 to 2 g. The film consisting of the bayberry-like TiO2-1.68 sample had a water contact angle of 2° without UV irradiation, and its superhydrophilic property could be ascribed to the cooperative effect between the surface roughness and high density of surface hydroxyl groups. This demonstrates that nanoflower mesoporous TiO2 microspheres with a rough surface can be obtained via the kinetics-controlled method, which can provide a new method for designing mesoporous TiO2 with different structures, surface morphologies and multi-functionalities.

In this study, we synthesized a bayberry-like Ni–Co–Mn ternary hydroxide with a secondary nanoneedle structure using a modified and cost-effective hydrothermal process assisted by the surfactant cetyltrimethylammonium bromide (CTAB). The incorporation of CTAB and graphene in the preparation process significantly enhances the electrochemical performance of NiCoMn–OH. The achieved results are truly impressive, with a high specific capacity of 1450 F g −1 and an outstanding capacity retention of 52.57% over 5000 cycles. The superior performance could be attributed to the specific bayberry-like microstructure with high effective specific surface area, which allowed for facile and rapid transport of ions and electrons. Moreover, the synergistic effect of CTAB and graphene proved to be crucial in stabilizing the Co 2+ and Mn 2+ ions within the ternary hydroxide structure. We developed a hybrid capacitor using a NiCoMn–OH-CTAB/Graphene composite electrode and an active electrode, which delivered a superior energy density of 50.79 Wh kg −1 at a power density of 400 W kg −1 and a cycling stability of 60.37% after 10000 cycles. These results indicate that the NiCoMn–OH-CTAB/Graphene composite electrode has great potential as an electrode material for energy storage devices.
