Paper Title:
Ultrasonic Characterization of Silver Nanoparticles
  Abstract

Nanoparticles exhibit unusual properties in contrast with their bulk properties due to small particle size and quantum confinement. In the present work, ultrasonic velocity and density measurements have been carried out in solutions of silver nanoparticles in micellar dispersion of cetyl tri-metyl ammonium bromide, CTAB. Ultrasonic velocity measurements at different concentrations of surfactant and temperatures were carried out using Sing-Around technique, operated at 2MHz. It is observed that ultrasonic velocity and adiabatic compressibility show abnormal behaviour with increase in concentration of CTAB in the solution, indicating the existence of the phase separations in nano-colloidal solution.
