Ferrofluid Leidenfrost droplets [PDF]

Soft Matter, 2019
We experimentally investigate the behavior of ferrofluid Leidenfrost droplets subject to a magnetic field gradient. As a droplet evaporates, it experiences a bouncing instability and finally takes off when its radius reaches a critical value.

Fine tuning and MOND in a metamaterial “multiverse”

Scientific Reports, 2017
We consider the recently suggested model of a multiverse based on a ferrofluid. When the ferrofluid is subjected to a modest external magnetic field, the nanoparticles inside the ferrofluid form small hyperbolic metamaterial domains, which from the ...
