The measurement of dynamic surface tensions of highly viscous liquids by the maximum bubble pressure method

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract A newly designed apparatus based on the principle of maximum bubble pressure can be used for measuring the dynamic surface tension in a time interval from 1 ms to 10 s. The surface tension values for pure liquids obtained at small lifetimes are influenced by hydrodynamic effects.

The effect of capillary characteristics on the results of dynamic surface tension measurements using the maximum bubble pressure method

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Abstract The dynamic surface tension of Triton X-100 solutions was measured using the maximum bubble pressure method (MBPM). The data obtained depended on the geometry and material of the capillaries employed. It is shown that reliable results are obtained with short capillaries of hydrophobic internal surfaces.

A test of the maximum bubble pressure method for electrocapillary measurements

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1987
Abstract The reliability of the maximum bubble pressure method for electrocapillary measurements has been tested in aqueous and non-aqueous solutions. The results suggest that, although contact angle problems are actually eliminated by using this method, serious systematic errors may be observed.

Measurement of the surface tension of electrolytic copper by the maximum gas bubble pressure method

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1964
1. The surface tension of electrolytic copper at 1600° has been measured and found to be 1230 dyne/cm. 2. The possibility has been shown of experimentally confirming the correctness of the use of external radii in calculating a from Cantor's formula or from Sugden's formula in the investigation of non-wetting liquids.
