Living droplets with mesoscale swimmers
L. Malik, N. Sharadhi, C. Prêcheur Llarena +5
We study the activity of 'living' droplets, which confine tens of swimming meso-organisms in 3D using a superhydrophobic substrate. With few swimmers, the droplet oscillates at its…
Interaction of vortex rings generated by two unsynchronised drop impacts
Anna A. L. Huttunen, Guilherme Moreira Bessa, Matilda Backholm
A liquid drop falling into a deep pool can create a vortex ring at the right impact conditions. Such drop-formed vortex rings are of importance in nature and technology and the dyn…
Ultra-slow capillary rise on hydrogel surfaces
Anagha Datar, Joonas Ryssy, Aku O. Toivonen +1
Capillary rise occurs when a thin tube contacts a liquid, which rises against gravity due to the capillary force. This phenomenon is present in a wide range of everyday and industr…
Forces and symmetry breaking of a living meso-swimmer
Rafael A. Lara, N. Sharadhi, Anna A. L. Huttunen +4
Swimming is ubiquitous in nature and crucial for the survival of a wide range of organisms. The physics of swimming at the viscosity-dominated microscale and inertia-dominated macr…
Soft matter mechanics of immune cell aggregates
Shohreh Askari, Guillem Saldo Rubio, Anagha Datar +3
T-cells are a crucial subset of white blood cells that play a central role in the immune system. When T-cells bind antigens, it leads to cell activation and the induction of an imm…
