    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. …”

    Synchronized observation of pressure wave influence on plasma–target interaction using optical wave microphone and high-speed camera by Thuzar Phyo Wai, Nway Htet Htet Myo, Kota Hagiwara, Fumiaki Mitsugi

    Published 2025-01-01
    “…One of the most important observations on what plasma jets emit is pressure waves, which have been focused on the energic distribution of electric discharges in atmospheric pressure. A unique optical technique called an optical wave microphone works based on the Fraunhofer diffraction of laser for phase objects, and it has successfully detected shockwaves emitted by helium and argon plasma jet at the downstream of the plasma jet in the applied voltage frequency order of kilohertz. …”
