This paper reports a numerical and experimental study of acoustic streaming and micromixing in polydimethylsiloxane microchannels. The mixing between two fluids flowing in microchannels was evaluated through the following conditions: (1) using a 28 μm thick β-poly(vinylidene fluoride) (β-PVDF) as a piezoelectric transducer actuated with a 24 Vpp and 40 MHz sinusoidal voltage; (2) using different flow...
Evidences of ultrasound enhancement of fibrinolysis - called sonothrombolysis - using acoustic beams in the kHz range pointed out acceleration of enzymatic processes and improvement in the tissue penetration of sound waves in comparison with MHz range trials. However, trials using kHz range increased bleeding rates in strokes cases due to the formation of standing waves in the brain. This paper describes...
