An inverse method to fast-track the calculation of phase diagrams for sonoluminescing bubbles

Ultrasonics Sonochemistry, 2021
A sound driven air bubble can be transformed into an argon bubble emitting light pulses stably. The very foundation to investigate the sonoluminescing bubble is to accurately determine the ambient radius and gas composition in the interior.
