--- Control of Chemical Reactions through Nonlinear Ultrasonic Phenomena --- The Ultrasonic System Research Institute has developed an experimental device for controlling chemical reactions using ultrasonic waves by utilizing the technology to control nonlinear ultrasonic phenomena (acoustic flow). This technology controls ultrasonic waves (cavitation and acoustic flow) tailored to specific purposes by measuring and confirming the interactions within the container and through ultrasonic control using a megahertz ultrasonic oscillation probe. Note: Ultrasonic Control By setting the oscillation conditions for sweep oscillation and pulse oscillation using two types of nonlinear resonant ultrasonic oscillation probes, it dynamically controls high-frequency propagation states above 30 MHz through high sound pressure resonance phenomena and harmonic generation phenomena (nonlinear phenomena). Note: Ultrasonic Control "Precision Cleaning Example" Sweep Oscillation: 70 kHz - 15 MHz, 15 W Pulse Oscillation: 13 MHz, 8 W In particular, the dynamic characteristics of harmonics through acoustic flow control enable reactions and responses at the nano level. This has been applied and developed from the example of dispersing metal powder to nanosize.
