Abstract To date, the synthesis of crystalline ZnO nanostructures was often performed under high temperatures and/or pressures with tiny output, which limits their commercial applications. Herein, we report progress on synthesizing single-crystalline nanosheets ambient conditions (i.e., room temperature (RT) and atmospheric pressure) based a sonochemistry strategy. Furthermore, controllable gro...

Abstract Dual-perspective high-speed imaging and acoustic detection is used to characterise cavitation activity at the tip of a commercial 20 kHz (f0) ultrasonic horn, over 2 s sonications across range input powers available (20 – 100%). Imaging 1 × 105 frames per second (fps) captures cavitation-bubble cluster oscillation horn-tip for duration sonication. Shadowgraphic 2 Mfps, from an orthogon...

<p style='text-indent:20px;'>The Jordan–Moore–Gibson–Thompson (JMGT) equation is a well-established and recently widely studied model for nonlinear acoustics (NLA). It third–order (in time) semilinear Partial Differential Equation (PDE) with distinctive feature of predicting the propagation ultrasound waves at <i>finite</i> speed. This due to heat phenomenon known as <i>...
