Thermodynamic method of B/A analysis of liposome suspensions: prediction via single relaxation theory

The enhanced ultrasonic nonlinear B/A measurements (via thermodynamic method) from liposome systems first reported by Zhang and coworkers are analyzed through relaxation theory. The enhanced ultrasonic absorption and sound velocity dispersion due to lipid structural relaxation are theoretically shown to accurately predict the enhanced B/A findings reported by Zhang and coworkers.
