Effect of Focused Ultrasound on Residual Particle Size Distribution in Water

概要

論文の詳細を見る
The residual particle distribution in pure water could be a problem in the nanoscience fields because nanoparticles are usually suspended in pure water such as deionized or distilled water. The effect of ultrasound on the residual particle distribution in pure water should be analyzed because the nano particles used in nanoscience are usually dispersed using ultrasound power. In this study, using a cylindrical piezoelectric vibrator, a noncontact-type focusing ultrasound system was fabricated to keep the purity of the water. The residual particle distribution in pure water was investigated. The number of residual particles increased as the ultrasound exposure time increased.
