| Research Abstract |
A novel technique using ultrasound waves has been developed in order to evaluate the diameter of the micron-size particles. Unlike the optical techniques, this method allows one to evaluate the particle structure and dynamics without dilution of the highly turbid suspensions. In this study, the sedimentation velocity and its fluctuations were respectively evaluated from the directions parallel and perpendicular to the gravity. The velocity was further converted to the diameter of the particles dispersed in water.
