Lab. of tensiometry and interfacial rheology (Genoa)

Investigation of the interfacial properties of surfactant systems and mixed surfactants-nanoparticles layers at liquid/air and liquid/liquid interfaces. These systems are characterized as concerns their phisico-chemical and dynamic properties. The accessible range of temperature spans from 5 to 50 °C.

  • EQUIPMENT:
