Abstract The concept of active nucleation sites is examined in the light of standard nucleation theory and it is suggested that these sites are probably small re-entrant corners or jogs in growth steps on the surface of the nucleating particle. The nucleation behavior of a spherical particle with a conical pit on its surface is examined in detail and the activity of a population of particles having a log-normal distribution of such pits is worked out. The parameters involved in the theory can…

The role of surface topography in promoting crystallization of ice and different organic crystals is investigated and it is shown that acute geometries are highly effective in promoting the growth of a confined crystalline phase, which then gives rise to a bulk phase.

The first experimental demonstration of a two-step mechanism that facilitates deposition of crystals on solid surfaces from vapor that occurs from saturated vapor without the need for supersaturation, conditions that, according to CNT, cannot lead to direct deposition ofstals from vapor.
