Effects of ultrasonic cavitation and heat deposition in aqueous suspensions of mesoporous silicon nanoparticles

The effects of ultrasonic cavitation and heat deposition in aqueous suspensions of mesoporous silicon nanoparticles were experimentally investigated using an original setup enabling precise temperature control and registration of cavitation by harmonics analysis of the transmitted signal. The obtained results reveal significant lowering of cavitation thresholds and heating of suspensions as compared to pure water.
