Fig. 3From: Nickel nanoparticles inside carbon nanostructures: atomistic simulationa Average potential energy per atom versus temperature for Ni34. Atoms of the NP are colored in accordance with its potential energy. b The average interatomic distance as a function of temperature for Ni34 for surface atoms (black squares) and core atoms (red triangles). c Radial distribution function for temperatures 0 K, 300 K, 600 K and 1300 K for Ni382Back to article page
