Importance of acoustic shielding in sonochemistry

Importance of shielding blood donors from harm.

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 ...

Importance of inharmonicity in the acoustic Guitar

Audibility of inharmonicity in realistic acoustic guitar tones was studied through formal listening experiments. Test tones were synthesized using an FZ-ARMA model of acoustic guitar sounds, which allows accurate control of the inharmonic partials. Inharmonicity was detected fairly easily for the lowest strings if the plucking transient was left out of the sound, but much harder for the full so...

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...
