Controlled tempering of lipid concentration and microbubble shrinkage as a possible mechanism for fine-tuning microbubble size and shell properties

Intesar O. Zalloum, Amin Jafari Sojahrood, Ali A. Paknahad +3

The acoustic response of microbubbles (MBs) depends on their resonance frequency, which is dependent on MB size and shell properties. Monodisperse MBs with tunable shell properties…

On the threshold of 1/2 order subharmonic emissions in the oscillations of ultrasonically excited bubbles

A. J. Sojahrood, N. R. Shirazi, H. Haghi +2

The pressure threshold for 1/2 order subharmonic (SH) emissions and period doubling during the oscillations of ultrasonically excited bubbles is thought to be minimum when the bubb…

Nonlinear energy loss in the oscillations of coated and uncoated bubbles: Role of thermal, radiation damping and encapsulating shell at various excitation pressures

AJ Sojahrood, H Haghi, Q Li +3

A simple generalized model (GM) for coated bubbles accounting for the effect of compressibility of the liquid is presented. The GM was then coupled with nonlinear ODEs that account…

Critical corrections to formulations of nonlinear energy dissipation of ultrasonically excited bubbles and a unifying parameter to asses and enhance bubble activity in applications

AJ Sojahrood, H Haghi, R Karshafian +1

Nonlinear oscillations of bubbles can significantly increase the attenuation of the host media. Optimization of bubble related applications needs a realistic estimation of the medi…
