Dancing Magnetic Droplets
Self assembly of magnetic droplets and magnetically triggered droplet splitting on superhydrophobic surfaces.
Self-assembly is ubiquitous in nature and both functionally and structurally complex structures can be achieved by using equilirbium and non-equilibrium self-assembling process. Timonen et al. have now demonstrated how different states equilibrium and dynamic self-assembly can be trapped and distinguished using ferrofluid droplet on a super-hydrophobic surface.
