Hello, all,
when two nanopartilces collide to form one larger particle, presumably there are some heat release (latent enthalpy or due to decrease of surface area) which could lead to temperature increase / annealing of the particle. My questions are how significant the annealing? Are there any experimental evidence that annealing does occurs? Is there any simple way to model the particle growth/annealing process?
If significant, it could lead to, for example, two amorphous nano particle collide to form one big crystalline particle.
Any related comments (with some references) are welcome.
It’s more than significant - it’s a given in the dry based on solid-solid diffusion. Will provide some references later when not on iPhone.

Look for an excellent NIST paper within the presentations.
