    Mario D’Ambrosio1, Elisabetta Bigagli1,*, Lorenzo Cinci1, Cecilia Brunetti2,*, Edgardo Giordani3, Francesco Ferrini3, Cristina Luceri1

    Phyton-International Journal of Experimental Botany, Vol.95, No.1, 2026, DOI:10.32604/phyton.2026.073250 - 30 January 2026

    Abstract Moringa oleifera (MO) is traditionally used to mitigate inflammatory-mediated disorders; however, the influence of ecotypic variation on its anti-inflammatory activity remains poorly understood. In this study, we compared the phytochemical composition and anti-inflammatory activity of ethanolic extracts obtained from fresh and dried leaves of four MO ecotypes (India, Paraguay, Mozambique, and Pakistan), all grown under the same outdoor conditions, as well as two commercial powders (Just Moringa and WISSA), using LPS-stimulated RAW 264.7 macrophages. Extracts from fresh leaves were 19–43% more cytotoxic than those from dried leaves, depending on the ecotype, likely due to higher cyanogenic… More >

    Photothermal Methane-to-Ethanol Conversion over Cu Single-Atom–Cu9S5 Coupled Crystalline Carbon Nitride

    Xiaohan Zhang1, Han Song2,*, Maoyuan Yin3, Xiaoli Rong2

    Chalcogenide Letters, Vol.23, No.1, 2026, DOI:10.32604/cl.2026.076594 - 26 January 2026

    Abstract We report the rational design and synthesis of a novel trifunctional catalyst comprising atomically dispersed copper single-atom (Cu-SAC) sites and Cu9S5 nanoparticles co-loaded onto a highly crystalline carbon nitride (CCN) support for the photothermal conversion of methane to ethanol. The distinct active sites operate in synergy: the Cu-SAC sites, coordinated to the nitrogen-rich CCN framework, serve as highly efficient centers for the initial activation of methane’s C-H bond to form methyl radicals, while the plasmonic Cu9S5 nanoparticles act as dedicated sites for the subsequent C-C coupling and partial oxidation steps, driven by a combination of photochemical More >

    Comparative Study on the Phenolic Compound Extraction in the Biorefinery Upgrading Process of Multi-Feedstock Biomass Waste Based Bio-Oil

    Haniif Prasetiawan1,2,*, Dewi Selvia Fardhyanti1, Hadiyanto2, Widya Fatriasari3

    Journal of Renewable Materials, Vol.13, No.7, pp. 1347-1366, 2025, DOI:10.32604/jrm.2025.02024-0070 - 22 July 2025

    Abstract Bio-oil is a renewable fuel that can be obtained from biomass waste, such as empty palm fruit bunches, sugarcane bagasse, and rice husks. Within a biorefinery framework, bio-oil had not met the standards as a fuel due to the presence of impurities like corrosive phenol. Therefore, the separation of phenol from bio-oil is essential and can be achieved using the extraction method. In this study, biomass wastes (empty fruit bunches of oil palm, sugarcane bagasse, and rice husk) were pyrolyzed in a biorefinery framework to produce bio-oil, which was then refined through liquid-liquid extraction with… More >

    Abstract Agastache rugosa, a medicinal plant known for its bioactive compounds, has gained attention for its pharmacological and commercial potential. This study aimed to optimize ethanol concentration to enhance growth and bioactive compound production in A. rugosa cultivated in a controlled plant factory system. Ethanol treatments at 40 and 80 mM significantly promoted both vegetative and reproductive growth. Plants treated with these concentrations exhibited higher net photosynthetic rates (A) and intercellular CO2 concentration (Ci) compared to the untreated control, whereas stomatal conductance (gs) and transpiration rate (E) remained unaffected. Chlorophyll and carotenoid concentrations, and SPAD values, significantly increased with ethanol… More >

    Darya Ivashkevich, Arina Ponomarenko*, Igor Manzhulo, Inessa Dyuizen

    BIOCELL, Vol.49, No.4, pp. 607-627, 2025, DOI:10.32604/biocell.2025.061606 - 30 April 2025

    Abstract The high prevalence of obesity and associated nonalcoholic fatty liver disease (NAFLD) in the population determines the increased interest in identifying molecular targets for regulating the processes underlying these pathologies. The search for new endogenous bioregulators of lipid metabolism and their inclusion in therapeutic regimens for the treatment of patients is becoming a potentially promising direction in science and medicine. Oleoylethanolamide (OEA) is an endogenous lipid mediator capable of exerting multiple hypolipidemic, anti-inflammatory, and hepatoprotective effects mediated by agonism with receptors of the peroxisome proliferator-activated receptor (PPAR) family (PPAR-α and PPAR-γ). This review focuses on More >

    The Effects of the Geometry of a Current Collector with an Equal Open Ratio on Output Power of a Direct Methanol Fuel Cell

    Yingli Zhu1,*, Jiachi Xie1, Mingwei Zhu1, Jun Zhang2, Miaomiao Li3

    Energy Engineering, Vol.121, No.5, pp. 1161-1172, 2024, DOI:10.32604/ee.2024.041205 - 30 April 2024

    Abstract The open ratio of a current collector has a great impact on direct methanol fuel cell (DMFC) performance. Although a number of studies have investigated the influence of the open ratio of DMFC current collectors, far too little attention has been given to how geometry (including the shape and feature size of the flow field) affects a current collector with an equal open ratio. In this paper, perforated and parallel current collectors with an equal open ratio of 50% and different feature sizes are designed, and the corresponding experimental results are shown to explain the… More >

    Journal of Polymer Materials, Vol.40, No.3-4, pp. 125-139, 2023, DOI:10.32381/JPM.2023.40.3-4.1

    Abstract A one dimensional isothermal model is proposed by modelling the kinetics of methanol transport at anode flow channel (AFC), membrane and cathode catalyst layer of direct methanol fuel cell (DMFC). Analytical model is proposed to predict methanol cross-over rate through the electrolyte membrane and cell performance. The model presented in this paper considered methanol diffusion and electrochemical oxidation at the anode and cathode channels. The analytical solution of the proposed model was simulated in a MATLAB environment to obtain the polarization curve and leakage current. The effect of methanol concentration on cell voltage and leakage More >

    Abstract Phytophthora nicotianae causes substantial economic losses in most countries where tobacco is produced. At present, the control of P. nicotianae mainly depends on chemical methods, with considerable environmental and health issues. We investigated the effects of ethanol extracts from Scutellaria baicalensis Georgi (SBG) and Magnolia officinalis (MO). On mycelial growth, sporangium formation, and zoospore release of P. nicotianae. Both extracts inhibited the growth of P. nicotianae, with mycelial growth inhibition rates of 88.92% and 93.92%, respectively, at 40 mg/mL, and EC50 values of 5.39 and 5.74 mg/mL, respectively. The underlying mechanisms were the inhibition of sporangium formation, the reduction of zoospore More >
