The cavitation valley phenomenon of rectangular wave modulation ultrasound

Synthesis of pure monoclinic zirconia nanoparticles using ultrasound cavitation technique

In the current study, synthesis and characterization of a new nano-structured zirconium(IV)-minoxidil complex (1), where minoxidil, (C9H15N5O; 6-(1-Piperidinyl)-2,4-pyrimidinediamine 3-oxide), have been investigated in two different solvents. The compound 1 has been synthesized by sonochemical method in the presence of methanol and monoethylene glycol (MEG) as solvents and characterized by scan...

Spatial Control of Cavitation in Therapeutic Ultrasound

Inertial cavitation has been implicated as the primary mechanism for a host of emerging applications. In all these applications, the main concern is to induce cavitation in perfectly controlled locations in the field; this means specifically to be able to achieve cavitation threshold at the geometrical focus of the transducer without stimulating its near field. In this study, we make use of dua...

Shock-wave model of acoustic cavitation.

Shock-wave model of liquid cavitation due to an acoustic wave was developed, showing how the primary energy of an acoustic radiator is absorbed in the cavitation region owing to the formation of spherical shock-waves inside each gas bubble. The model is based on the concept of a hypothetical spatial wave moving through the cavitation region. It permits using the classical system of Rankine-Hugo...

Blackbody Radiation in the Rectangular Wave Guide

Electromagnetic (EM-)fluctuations in the rectangular wave guide are considered. In the limit of the empty (lossless) wave guide the partial mode densities, the volume averaged correlations and the internal energy are discussed in both, the high and the low temperature representation. The results are compared with the corresponding quantities in the cube, the slab resonator and the infinite isot...
