Evolution of Pores in Nanoshells — a Competition of Direct and Inverse Kirkendall Effects, Frenkel and Gibbs–Thomson Effects: the Phenomenological Description and Computer Simulation

Evolution of Pores in Nanoshells — a Competition of Direct and Inverse Kirkendall Effects, Frenkel and Gibbs–Thomson Effects: the Phenomenological Description and Computer Simulation

The review consists of analysis of causes, driving forces, and mechanisms of formation and shrinkage of pores within the nanoparticles with a closed geometry. Taking into account the effects analysed within the scope of quasistationary approximation, several phenomenological models are proposed to d...
