Heterogeneous Nucleation

Some articles on heterogeneous nucleation, nucleation, heterogeneous:

Mechanics of Nucleation - Heterogeneous Nucleation
... Heterogeneous nucleation occurs much more often than homogeneous nucleation ... such as phase boundaries or impurities like dust and requires less energy than homogeneous nucleation ... is lower, thus diminishing the free energy barrier and facilitating nucleation ...
Crystal Growth - Nucleation
... Nucleation can be either homogeneous, without the influence of foreign particles, or heterogeneous, with the influence of foreign particles ... Generally, heterogeneous nucleation takes place more quickly since the foreign particles act as a scaffold for the crystal to grow on, thus eliminating ... Heterogeneous nucleation can take place by several methods ...
