Chemical Bubble Dynamics and Quantitative Sonochemistry

We model the collapse of a bubble by taking into account all the energy forms involved (i.e., mechanical, thermal, chemical, and radiative) and compare the calculated radical yields with sonochemical data in H2O. Water decomposition plays a critical role in the energy balance, but trails equilibrium even in bubbles collapsing at subsonic speeds. Integration of the equation of bubble motion coup...

Sonochemistry and sonoluminescence in microfluidics.

One way to focus the diffuse energy of a sound field in a liquid is by acoustically driving bubbles into nonlinear oscillation. A rapid and nearly adiabatic bubble collapse heats up the bubble interior and produces intense concentration of energy that is able to emit light (sonoluminescence) and to trigger chemical reactions (sonochemistry). Such phenomena have been extensively studied in bulk ...

Mechanochemistry and sonochemistry: concluding remarks.

This paper offers a perspective on mechanochemistry and offers summarizing commentary on the Faraday Discussion 170, "Mechanochemistry: From Functional Solids to Single Molecules". The connection between the mechanical and the chemical worlds dates back to our earliest written records and beyond, but its renaissance over the past decade or so has had an impact on a huge swathe of modern science...

Analytical sonochemistry: a review

Analytical chemistry is one of the chemical areas where ultrasonic radiation has been only infrequently used (namely in sample pretreatment, separations, automatic analytical systems and clinical analysis). This auxiliary technique would constitute a powerful aid in the automation of several steps in analytical processes: its advantages and disadvantages, as well as its use and potential in the...
