The Journal of Physical Chemistry A, 1998
Very few papers are devoted to the study of the chemical effects of pulsed ultrasound in the low-frequency range. The present work consists of a systematic experimental study of the effects of pulsed ultrasound in the 20 kHz range using an immersed titanium horn.

Sonoluminescence and sonochemistry
1997 IEEE Ultrasonics Symposium Proceedings. An International Symposium (Cat. No.97CH36118), 2002The chemical effects of ultrasound originate from acoustic cavitation, which produces extremely energetic local transient conditions. In cavitating clouds of bubbles, both sonochemistry and sonoluminescence occur. Spectroscopic analysis of sonoluminescence from hydrocarbons and from metal carbonyls reveal temperatures of /spl sim/5000 K, /spl sim/1000 ...

Sonochemistry of carbohydrate compounds
Carbohydrate Research, 2001A literature survey of carbohydrate sonochemistry is presented. The basic physical principles are discussed qualitatively before the main applications are reviewed. Along with other non-classical activation methods developed in accordance with 'Green Chemistry' requirements, ultrasonic irradiation offers important potential for the conversion of ...

1998
For many years, sonochemistry of solutions appeared of limited interest for synthesis. The initial studies, essentially effected on aqueous solutions, gave disappointing results, low rates, yields, and selectivities. In addition, the theoretical understanding was inadequate.
