Theory of Coherent Nucleation in Phase-Separating Nanoparticles

The basic physics of nucleation in solid single-crystal nanoparticles is revealed by a phase-field theory that includes surface energy, chemical reactions, and coherency strain. In contrast to binary fluids, which form arbitrary contact angles at surfaces, complete “wetting” by one phase is favored...
