Atomistic Mechanisms for the Nucleation of Aluminum Oxide Nanoparticles [PDF]

open access: yesThe Journal of Physical Chemistry A, 2015
A predictive model for nanoparticle nucleation has not yet been successfully achieved. Classical nucleation theory fails because the atomistic nature of the seed has to be considered since geometrical structure as well as stoichiometry do not always match the bulk values.
