    Fast Rate Production of Biodiesel from Neem Seed Oil Using a Catalyst Made from Banana Peel Ash Loaded with Metal Oxide (Li-CaO/Fe2 (SO4)3) by Ismail J. Madai, Yusufu Abeid Chande Jande, Thomas Kivevele

    Published 2020-01-01
    “…Decomposition profile of CBA was displayed by thermal gravimetric analysis (TGA), whereas in-depth analysis by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray fluorescence (X-RF), and Fourier-transform infrared spectroscopy (FT-IR) revealed that the high efficiency displayed by a catalyst from banana ash calcined at 650°C was due to the presence of potassium carbonate (K2CO3), a calcium magnesium silicate (CaMgSiO4), and potassium sodium sulphate (KNaSO4) contents that accounted for the high basicity of up to 11.09. Additionally, the nitrogen adsorption/desorption studies revealed that CBA interestingly exhibits a high BET surface area of 411.2 m2/g and promising mesopores (3.014 nm). …”

    A Comparative Analysis of the Antioxidant Profiles Generated by the RoXsta<sup>TM</sup> System for Diverse Biological Fluids Highlights the Powerful Protective Role of Human Semina... by Robert J. Aitken, Alexandra Wilkins, Natasha Harrison, Mohammad Bahrami, Zamira Gibb, Kaitlin McIntosh, Quan Vuong, Sarah Lambourne

    Published 2025-01-01
    “…The powerful antioxidant properties of human semen were shown to reside within the seminal plasma (SP) fraction, rather than the spermatozoa, and to be resistant to snap freezing in liquid nitrogen. Moreover, comparative studies demonstrated that human SP exhibited significantly (<i>p</i> < 0.001) higher levels of antioxidant potential than any other species examined (stallion, bull, dog) and that this intense activity reflected the relative vulnerability of human spermatozoa to peroxide attack. (4) Conclusions: The RoXsta<sup>TM</sup> system provides valuable information on the antioxidant profile of complex biological fluids, supporting its diagnostic role in conditions associated with oxidative stress. …”
