Effect of surfactants on inertial cavitation activity in a pulsed acoustic field
Article Abstract:
Sonoluminescence and passive cavitation detection (PCD) are studied in order to examine the acoustic cavitation field generated at different acoustic pulse lengths in the presence of an anionic surfactant, sodium dodecyl sulfate (SDS). It is observed that as the concentration of surfactant increases, acoustic cavitation activity also increased, while at long pulse lengths acoustic cavity activity is enhanced at low SDS concentrations.

Effect of surfactants on the rate of growth of an air bubble by rectified diffusion
Article Abstract:
The rectified diffusion growth of a single air bubble levitated in an acoustic field in water and in aqueous solutions containing surfactants sulfate like sodium dodecylbenzene sulfonate and sodium dodecyl sulfate, is investigated. The presence of surfactants at the bubble/liquid interface enhanced the growth of the bubble by rectified diffusion.

Effect of alcohols on the initial growth of multibubble sonoluminescence
Article Abstract:
The effect of alcohols on the initial growth of the multibubble sonoluminescence (MBSL) intensity in aqueous solutions is investigated. The results have shown that the decrease in the steady state ([N.sub.crit]) at higher alcohol concentrations might be caused by an increase in the bubble growth by rectified diffusion.
