    Ag-Ag2O nanocomposite biosynthesis by mixed bacterial cultivation and effect of the ph on size and optical properties of the nanocomposite by Morad G. S. S. Al-Asbahi, Bashir A. Al-Ofiri, Fuad A. A. Saad, Adnan Alnehia, Muhammad Hadi

    Published 2025-02-01
    “…A range of analytical techniques, including X-ray Diffraction (XRD), UV-visible Spectroscopy (UV-vis), Fourier Transform Infrared Spectroscopy (FTIR), and Transmission Electron Microscopy (TEM), were employed to investigate the structural and optical characteristics of the nanocomposites. XRD analysis confirmed the presence of cubic phases of Ag and Ag2O, with crystallite sizes varying from 8 to 44 nm; notably, smaller crystallites were observed at a pH of 6.5. …”
