Bubble jetting in acoustic microdroplet vaporization
Anunay Prasanna, Samuele Fiorini, Gazendra Shakya +1
Acoustic droplet vaporization denotes the phase-change of micron- and sub-micron-sized droplets upon the application of high-amplitude ultrasound. The asymmetric collapse of the in…
Cavitation by phase shift of focused shock waves inside a droplet
Samuele Fiorini, Guillaume T. Bokman, Anunay Prasanna +6
Localized cavitation in liquids and soft tissues, typically initiated by the rarefaction phase of high-amplitude ultrasound waves, is leveraged in several biomedical applications s…
Measurement of traveling pressure waves inside a droplet
Sayaka Ichihara, Samuele Fiorini, Yoshiyuki Tagawa +1
Shock wave-droplet interactions have been receiving increasing attention due to their relevance in aviation fuel combustion and minimally invasive medical treatments, yet quantifyi…
Shock compression-based equation of state for perfluorohexane
Anunay Prasanna, Guillaume T. Bokman, Samuele Fiorini +4
Perfluorohexane is a biocompatible material that serves as a liquid core for acoustically-responsive agents in biomedical applications. Despite its relatively widespread usage, the…
Positive pressure matters in acoustic droplet vaporization
Samuele Fiorini, Anunay Prasanna, Gazendra Shakya +2
Acoustically vaporizable droplets are phase-change agents that can improve the effectiveness of ultrasound-based therapies. In this study, we demonstrate that the compression part…
