Effect of Pulse Shaping on Subharmonic Aided Pressure Estimation In Vitro and In Vivo. [PDF]
, 2016 OBJECTIVES: Subharmonic imaging (SHI) is a technique that uses the nonlinear oscillations of microbubbles when exposed to ultrasound at high pressures transmitting at the fundamental frequency ie, f METHODS: Eight waveforms with different envelopes were ...

Ultrasound-induced microbubble coalescence [PDF]
Ultrasound in Medicine & Biology, 2004 We studied the interaction of ultrasound contrast agent bubbles coated with a layer of lipids, driven by 0.5 MHz ultrasound. High-speed photography on the submicrosecond timescale reveals that some bubbles bounce off each other, while others show very fast coalescence during bubble expansion.

Polymer Mechanochemistry in Microbubbles
Advanced Materials, 2023 AbstractPolymer mechanochemistry is a promising technology to convert mechanical energy into chemical functionality by breaking covalent and supramolecular bonds site‐selectively. Yet, the mechanochemical reaction rates of covalent bonds in typically used ultrasonication setups lead to reasonable conversions only after comparably long sonication times.
