ABSTRACT
Measurements of equilibrium and dynamic interfacial tension of liquid interfaces are of great importance for many practical applications. Many technological processes, e.g. involving liquid-liquid extraction, foams and emulsions, liquid metals and alloys, multiphase flows and many others, strongly depend on interfacial tension [1]. Interfacial tension is very important for the proper work of many biomedical systems, such as lung alveoli, wetting films on eyes [2, 3]. Moreover, the dynamic interfacial tension can be used for diagnostics of diseases [3, 4]. Also many environmental systems are strongly affected by detergents, which change the tension of water in nature. Thus, monitoring the interfacial tension of natural waters is an important issue also in environmental studies [5, 6].
