The spatial information about the sintering processes features a contrast between different cluster sizes. We evaluate this at the end of sintering simulations. and Pt 7 clusters form in the process, they hinder further sintering. This could be considered "reverse nucleation", where eventually sintering is restricted to some areas with a greater range of cluster sizes, not because that was where sintering initially began, but because that is where enough cluster size diversity remains to drive sintering. This gives us potential signatures to look for experimental systems of size-selected clusters or nanoparticles, when attempting to identify if a cluster size is stable or not; a stable cluster size would show overall little change, aside from some locations where much larger nanoparticles formed, while less stable cluster sizes would exhibit a much broader cluster size distribution throughout the sintering process.
