DOI: 10.1002/aic.15887
Abstract: We present a free-energy driven kinetic Monte Carlo model to simulate homogeneous nucleation of metal nanoparticles (NPs) from vapor phase. The model accounts for monomer-cluster condensations, cluster-cluster collisions, and cluster evaporations simultaneously. Specifically, we investigate… read more here.

DOI: 10.1016/j.jcrysgro.2021.126491
Abstract: In a solid-state diffusional phase transformation involving nucleation and growth, the size of the critical nucleus for a homogeneous process (r*homo=r* ) has been assumed to be a time invariant constant of the transformation. The… read more here.

DOI: 10.1111/jace.14963
Abstract: The refinement of Y2BaCuO5 (Y211) particles is a matter of significant importance in fabricating high performance YBa2Cu3O7-δ (Y123) superconductor bulks by top-seeded melt-growth (TSMG). However, coarsening and epitaxial growth naturally occur to the pre-existing Y211… read more here.
