Ultrasound causes high-energy chemistry. It does so through the process of acoustic cavitation: the formation, growth and implosive collapse of bubbles in a liquid. During cavitational collapse, intense heating of the bubbles occurs. These localized hot spots have temperatures of roughly 5000�C, pressures of about 500 atmospheres, and lifetimes of a few microseconds. Shock waves from cavitation in liquid-solid slurries produce high-velocity interparticle collisions, the impact of which is… 
Hot spot conditions during cavitation in water
Liquids irradiated with high-intensity ultrasound undergo acoustic cavitation--the formation, growth, and implosive collapse of bubbles. The energy stored during the growth of the bubble in the
Nanostructured Materials Synthesis Using Ultrasound
TLDR
Recent applications of ultrasound to the production of nanostructured materials are reviewed and chemical and physical phenomena associated with high-intensity ultrasound are responsible for the production or modification of nanomaterials.
Can sonochemistry take place in the absence of cavitation? - A complementary view of how ultrasound can interact with materials.
A hypothesis is advanced for a mechanism by which ultrasound could help to activate chemical reactions, even in the absence of cavitation. It is suggested that the compression phase of an acoustic
The Chemical History of a Bubble.
TLDR
The studies discussed herein have revealed that extraordinary conditions are generated inside the collapsing bubbles in ordinary room-temperature liquids: observable temperatures exceeding 15 000 K, pressures of well over 1000 bar (more than the pressure at the bottom of the Mariana Trench), and heating and cooling rates in excess of 1000 K·s-1.
The characterization of acoustic cavitation bubbles - an overview.
TLDR
In this overview, some recently developed experimental procedures for the characterization of acoustic cavitation bubbles have been discussed.

Acoustic cavitation is responsible for both sonochemistry and sonoluminescence. Bubble collapse in liquids results in an enormous concentration of energy from the conversion of the kinetic energy of
Sonochemistry: The Effect of Sonic Waves on Chemical Systems
Sonochemistry is the application of ultrasound to chemical reactions and processes. The mechanism causing sonochemical effects in liquids is the phenomenon of acoustic cavitation. The chemical
Ultrasound artificially nucleated bubbles and their sonochemical radical production.
TLDR
Numerical simulations of sonochemical conversion using the empirical bubble size distributions, for three different pressure amplitudes, are described and compared with experimental results.
Catalysis under ultrasonic irradiation: a sound synergy
Through selected examples, we report here that ultrasound is capable of assisting a solid catalyst in various reactions. Beside improvement of heat and mass transfer induced by the implosion of
