Acoustic levitation uses acoustic radiation forces to counteract gravity and suspend objects
in mid-air. Although acoustic levitation was first demonstrated almost a century ago, for a …

Levitation and controlled motion of matter in air have a wealth of potential applications
ranging from materials processing to biochemistry and pharmaceuticals. We present a …

This paper surveys contact micromanipulation strategies that are developed to tackle the
microscale-related phenomena in microassembly. Strategies are divided according to how …

We present a theoretical analysis of the acoustic radiation force on a single small spherical
particle, either a thermoviscous fluid droplet or a thermoelastic solid particle, suspended in a …

In automated production processes gras** devices and methods play a crucial role in the
handling of many parts, components and products. This keynote paper starts with a …

In this study, the acoustic nonlinear equation namely the confirmable time-fractional
Westervelt equation is under consideration analytically. This equation is applicable in the …

We demonstrate that acoustic levitation can levitate spherical objects much larger than the
acoustic wavelength in air. The acoustic levitation of an expanded polystyrene sphere of 50 …

We present the experimental demonstration and theoretical framework of an
acoustophoretic concept enabling contactless, controlled orbital motion or spinning of …

Direct in-droplet (in stillo) microreaction monitoring using acoustically levitated micro
droplets has been achieved by combining acoustic (ultrasonic) levitation for the first time …

The energy changes experienced during application of high-power ultrasound in cleaning
biofilms from food-grade surfaces was investigated in this study. Laboratory scale …
