Journal ArticleDOI
Model of single bubble sonoluminescence.
Yu An,C. F. Ying +1 more
TL;DR: The temperature within and the sonoluminescence characteristics of a stable inert-gas single bubble grown in water under some given conditions are computed by using a model that is as sufficiently complete as the authors can manage, except that possible chemical reactions within the bubble are neglected.

Magnetic nanoparticle supported amine: An efficient and environmental benign catalyst for versatile Knoevenagel condensation under ultrasound irradiation
TL;DR: Amine functionalized silica coated Fe3O4 nanoparticles (SiO2@MNP-A ) were successfully prepared as a novel heterogeneous amine in this paper, which was found to be a magnetically separable and highly active catalyst for ambient Knoevenagel condensation of aromatic aldehydes and α-aromatic (heteroaromatic or polyaromatic)-substituted methylene compounds in water under ultrasonic irradiation to afford the corresponding products in good to excellent yields.

Erosion evolution in mono-crystalline silicon surfaces caused by acoustic cavitation bubbles
David Fernandez Rivas,Joris Betjes,B. Verhaagen,Wilco Bouwhuis,Ton C. Bor,Detlef Lohse,Han Gardeniers +6 more
TL;DR: In this paper, the early stages of cavitation erosion of silicon surfaces were studied for three different crystallographic orientations, and a quantity defined as the ratio of the relative eroded area to the number of pits, αp, was introduced to evaluate the evolution of erosion among the different substrates used.

Behavior of laser-induced cavitation bubbles in liquid nitrogen
TL;DR: In this paper, the initial behavior and subsequent motion of a bubble in liquid nitrogen are investigated experimentally using high-speed photography, where a bubble is generated by focusing a pulsed ruby laser into liquid nitrogen at 78.0 K, changing the ambient pressures up to 253.1 kPa.

Acoustic cavitation: bubble dynamics in high-power ultrasonic fields
W. Lauterborn,R. Mettin +1 more
TL;DR: In this paper, the importance of bubble dynamics in acoustic cavitation of sound-irradiated liquids is emphasized starting from a discussion of cavitation thresholds, the oscillation of single, spherical bubbles in sound fields is described for various parameters (sound pressure amplitude, bubble radius, and acoustic frequency), including response curves and habitat diagrams.
