Outline of Final Research Achievements

I successfully developed a system of detecting temporal change of mechanical properties in surface or interface of sample materials, and have manufactured a proto type of measurement device, which will be commercially available. In this system, an originally developed technique based on the electromagnetically spinning method is used for remotely applying a controlled torque to a probe in/on sample materials. Owing to the advantage of its noncontact control of torque in this system, the high accuracy in measurement of low viscosity and/or low shear rate can be obtained. As a result, a sol-gel phase transition was directly observed, and the phase transition point was determined. Additionally, the relation between surface viscosity and surface shear rate for a monolayer of detergents was measured.
