Figure 1From: The effects of the size of nanocrystalline materials on their thermodynamic and mechanical propertiesA perfect crystal (A) and a nanoparticle taken out of it (B). (A) All the atoms are located at their equilibrium lattice positions. The atomic radius is r 0 and the density is ρ 0 . (B) The particle radius is compressed from R0 to R, the average gyration radius reduces to r, and the average density increases to ρ R .Back to article page
