    Ultrasonic study of polyethylene glycol and ethanol interactions: impact of concentration and temperature by Niharika Das, Subhraraj Panda, Manoj Kumar Praharaj

    Published 2025-06-01
    “…This study examines the molecular interactions between polyethylene glycol (PEG) at concentrations of 5%, 10%, and 15% with ethanol, utilizing ultrasonic techniques across temperatures of 25 °C, 35 °C, 45 °C, and 55 °C. Key acoustic parameters, including Acoustic Impedance (Z), Adiabatic Compressibility (β), Intermolecular Free Length (Lf), Relaxation Time, and Gibbs free energy, were evaluated using the experimental parameters “density (ρ) viscosity (η) and ultrasonic speed (U)”.The analysis focuses on understanding how temperature and concentration variations influence the properties, particularly ultrasonic velocity, density, viscosity, and acoustic parameters, in the PEG-ethanol solution. …”
