Abstract

The present study deals with, for the first time, a measurement of the number of bubbles of submicron in size before and after pressurization. Measurement of ultrafine bubbles of submicron size was conducted and it was clarified that greater number of submicron sized bubbles existed before the pressurization in comparison with that after the pressurization. The application of high pressure of gas for its dissolution into water and the ambient-pressure reduction has a possibility to increase the number of ultrafine bubbles.
