Research Abstract |
Various aspects of the effect of environment on the heterogeneous nucleation of bubbles, droplets and grains are investigated theoretically. In particular, we paid attention to various properties related to the dynamics of nucleation such as the morphology of the energy landscape of nucleation, the energy barrier at the saddle point which corresponds to the critical nucleus, the morphology of critical nucleus, and its unstable growing mode. We also studied the statistical mechanics of the ensemble of nuclei using Fokker-Planck formulation.
