| Outline of Final Research Achievements |
We developed a new system for the measurement of the mechanical properties of the fluids, such as the viscosity and the elasticity for the bulk materials. It is also effective for the layers formed on the liquid surface; we could successfully observe the two-dimensional viscosity of the adsorbed surface layer of the surfactant molecules on the aqueous solutions. The surface viscosity is important property of the monomolecular layers called Langmuir films, and its accurate determination would provide unique information of the condensation state of these two-dimensional materials. The most remarkable point of the technique is that we can remotely measure the viscosity of the sample in the completely confined environment. It would also be an advantage when it is applied for the measurement of the mechanical properties of fragile Langmuir films, since the films are quite sensitive for the external stimulation including the insertion of the mechanical probe.
