Figure 8. Examples of atomic trajectories of NPs with identical sizes at sintering temperatures of 50%Tm, and 70%Tm: (A) 5 nm Ag NPs, (B) 5 nm Cu NPs, (C) 15 nm Ag NPs, and (D) 15 nm Cu NPs. See Supplementary Materials for animations of selected key events. NPs: Nanoparticles; Tm: bulk melting points.
