Antibubbles enable tunable payload release with low-intensity ultrasound
Nicolas Moreno-Gomez, Athanasios G. Athanassiadis, Albert T. Poortinga +1
The benefits of ultrasound are its ease-of-use and its ability to precisely deliver energy in opaque and complex media. However, most materials responsive to ultrasound show a weak…
Directed Acoustic Assembly in 3D
Kai Melde, Minghui Shi, Heiner Kremer +7
The creation of whole 3D objects in one shot is an ultimate goal for rapid prototyping, most notably biofabrication, where conventional methods are typically slow and apply mechani…
Characterization of active matter in dense suspensions with heterodyne laser Doppler velocimetry
Johannes Sachs, S. Nikhilesh Kottapalli, Peer Fischer +2
We present a novel approach for characterizing the properties and performance of active matter in dilute suspension as well as in crowded environments. We use Super-Heterodyne Lase…
Active colloidal propulsion over a crystalline surface
Udit Choudhury, Arthur V. Straube, Peer Fischer +2
We study both experimentally and theoretically the dynamics of chemically self-propelled Janus colloids moving atop a two-dimensional crystalline surface. The surface is a hexagona…
