Abstract
We focus on the formation of self-assembled micrometer-sized rings of CoPt3 nanoparticles due to phase separation of a binary solution, giving rise to a bilayer Structure and Subsequent decomposition of the top layer into droplets. Evaporation of the remaining solvent from the droplet leads to a shrinking of its contact line. The nanoparticles located at the contact line follow its motion and self-assemble alone the line accordingly.
