    Adsorption of n-alkyl polyoxyethylene glycol ethers at liquid-vapour and liquid-liquid interfaces

    n-Alkyl polyoxyethylene glycol ethers (CiEOj’s) show peculiar adsorption properties at liquid interfaces. In fact, the partial hydrophobic character of the ethylene groups in the hydrophilic chain allows differen...

    Adsorption kinetics of alkyl phosphine oxides in water/alkane systems with transfer across the interface

    The adsorption kinetics of alkyl phosphine oxides soluble both in water and in alkanes has been experimentally studied by measuring the dynamic interfacial tension. To this aim the pendant drop method was used...

    Growth instabilities of bubbles and drops

    The results of this theory are of general validity and also apply in the case where a bubble of gas is growing from an orifice. Then this theory allows to explain some instabilities already observed in bubblin...

    Interfacial Tension and Contact Angle in Immiscible Systems by Capillary Pressure Measurements

    The recent development of experimentation in space, under microgravity conditions, makes it possible to measure the interfacial tension (σ) between immiscible fluids (organic compounds, liquid alloys…) by a st...
