Quartz resonator-based approach to ultrasonic rheology of a mixed-phase micellar system.

We report the application of a quartz crystal microbalance with dissipation monitoring (QCM-D) to rheology of mixed-phase micellar systems. This novel application of QCM-D allows for the facile monitoring of complex systems under a variety of conditions. Viscosity measurements were obtained for sodium dodecyl sulfate (SDS) solutions, ranging from 1.
