TL;DR: In this article, the authors evaluated the effectiveness of the ultrasonic process for depolymerization and viscosity control of the starch and polysaccharide solutions after gelatinization.

TL;DR: The lower bound of ambient radius for an active bubble in SL and sonochemical reactions nearly coincides with the Blake threshold for transient cavitation and the upper bound is in the same order of magnitude as that of the linear resonance radius.

TL;DR: Numerical simulations of bubble pulsations have been performed for a system of two bubble clouds to study the experimentally observed bubble motion under an ultrasonic horn by high-speed video camera and indicated that the bubble pulsation is strongly influenced by the interaction with surrounding bubbles.

TL;DR: Harmonics in cavitation noise are generated by both "stable" and "transient" cavitation bubbles which pulsate nonlinearly with the period of ultrasound, which results in the broad-band noise.

TL;DR: This study shows that one can tailor the magnetization and relaxation pattern by suitably controlling the particle size of the nanocrystalline ZnFe(2)O(4) particles, and results in a better pure phase system of nanoferrite with improved magnetic properties.
