The Quest for the Most Spherical Bubble [PDF]

, 2013
We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point-plasma generated by a nanosecond laser pulse. Unlike in previous studies, the laser is focussed by a parabolic

Effect of thermosonication on the UHPLC‐QTOF‐IMS‐based metabolomic profile of orange juice

JSFA reports, EarlyView.
Abstract Background This study investigated the impact of thermosonication on the metabolomic profile of orange juice to understand processing‐induced alterations in bioactive compounds and quality attributes. Results Moderate thermosonication at 45°C preserved structural siloxanes and certain amino acids, whereas higher temperatures between 60 and 75 ...

Bubble-bubble interaction: A potential source of cavitation noise

Physical Review E, 2009
The interaction between microbubbles through pressure pulses has been studied to show that it can be a source of cavitation noise. A recent report demonstrated that the acoustic noise generated by a shrimp originates from the collapse of a cavitation bubble produced when the shrimp closes its snapper claw.

High‐pressure homogenization and pH‐shifting modification of hazelnut protein isolates: Functional enhancement, allergenicity reduction, and probiotic microencapsulation performance

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plant‐based proteins, such as hazelnut protein isolates (HPIs), often exhibit limited solubility and functionality, as well as allergenic potential, thereby limiting their applicability in food products. This investigation sought to improve the techno‐functional characteristics of HPI and mitigate its allergenicity via high‐pressure

Mass transfer of acoustic cavitation bubbles in multi-bubble environment

Ultrasonics Sonochemistry
The mass transfer around acoustic cavitation in a multi-bubble environment was numerically studied. To model the multi-bubble environment, several bubbles were placed at the vertices of the polyhedron, and one bubble was placed at the center, and then an ultrasonic pressure wave with a frequency of 20 kHz was imposed along the simulation boundary box ...
