Surfactant-loaded capsules as Marangoni microswimmers at the air-water interface: Symmetry breaking and spontaneous propulsion by surfactant diffusion and advection
Hendrik Ender, Ann-Kathrin Froin, Heinz Rehage +1
We present a realization of a fast interfacial Marangoni microswimmer by a half-spherical alginate capsule at the air-water interface, which diffusively releases water-soluble spre…
Strong deformation of ferrofluid-filled elastic alginate capsules in inhomogenous magnetic fields
Christian Wischnewski, Elena Zwar, Heinz Rehage +1
We present a new system based on alginate gels for the encapsulation of a ferrofluid drop, which allows us to create millimeter-sized elastic capsules that are highly deformable by…
Pendant Capsule Elastometry
Jonas Hegemann, Sebastian Knoche, Simon Egger +5
We provide a C/C++ software for the shape analysis of deflated elastic capsules in a pendant capsule geometry, which is based on an elastic description of the capsule material as a…
Elastometry of Deflated Capsules: Elastic Moduli from Shape and Wrinkle Analysis
Sebastian Knoche, Dominic Vella, Elodie Aumaitre +4
Elastic capsules, prepared from droplets or bubbles attached to a capillary (as in a pendant drop tensiometer), can be deflated by suction through the capillary. We study this defl…
