A New Tensiometry Using Bubble and Laser Beam

Abstract

The present review gives a brief outline of the concept on the static surface tension and describes the

reliability, precision, and its applicability of a new tensiometry, optical bubble pressure method toward simple

to complex solution systems. The method improves the accuracy by eliminating adsorption of solute onto solid

component of the tensiometer and application to sol-gel transition phenomena is also described.
