Cubic Shapes of Nanoparticles (IMAGE) University of Helsinki Caption Originally close-to-spherical iron nanoparticle nuclei grow in magnetron sputter chambers either cubic or spheres. The research revealed a specific regime of temperature and deposition rates leading to thermodynamically unexpected cubic shapes of final nanoparticles.
