Abstract
Using in situ transmission electron microscopy, we demonstrated that gold nanoparticles are unified via ""oriented attachment"" assisted either by nanoparticle rotation or grain boundary migration at the attachment interface. We also observed that the combined nanoparticle changes shape with stable facet planes via surface diffusion, along with recrystallization. © 2013 The Royal Society of Chemistry.
