Model nanowires (Pdn)x were constructed from isolated cuboctahedral clusters Pdn (n=38, 79, 140, 225), as depicted for n=225. Periodic density functional calculations show that the elasticity of the nanoparticles plays a key role in the self-assembly mechanism. The results are also relevant to sintering in the catalysts by supported metal nanoparticles.
