Constant-power versus constant-voltage actuation in frequency sweeps for acoustofluidic applications
Fabian Lickert, Henrik Bruus, Massimiliano Rossi
Supplying a piezoelectric transducer with constant voltage or constant power during a frequency sweep can lead to different results in the determination of the acoustofluidic reson…
Flow profiles near receding three--phase contact lines: Influence of surfactants
Benedikt B. Straub, Henrik Schmidt, Peyman Rostami +5
The dynamics of wetting and dewetting is largely determined by the velocity field near the contact lines. For water drops it has been observed that adding surfactant decreases the…
DefocusTracker: A modular toolbox for defocusing-based, single-camera, 3D particle tracking
Rune Barnkob, Massimiliano Rossi
The need for single-camera 3D particle tracking methods is growing, among others, due to the increasing focus in biomedical research often relying on single-plane microscopy imagin…
Size-dependent particle migration and trapping in 3D microbubble streaming flows
Andreas Volk, Massimiliano Rossi, Bhargav Rallabandi +3
Acoustically actuated sessile bubbles can be used as a tool to manipulate microparticles, vesicles and cells. In this work, using acoustically actuated sessile semi-cylindrical mic…
A fast and robust algorithm for General Defocusing Particle Tracking
Massimiliano Rossi, Rune Barnkob
The increasing use of microfluidics in industrial, biomedical, and clinical applications requires a more and more precise control of the microfluidic flows and suspended particles…
General Defocusing Particle Tracking: fundamentals and uncertainty assessment
Rune Barnkob, Massimiliano Rossi
General Defocusing Particle Tracking (GDPT) is a single-camera, three-dimensional particle tracking method that determines the particle depth positions from the defocusing patterns…
