These particles were prepared from molecular precursors combined with a surface modification agent either by a photolytic or a thermal nucleation and growth step.
The presence of bulged grains indicates deformation at temperatures lower than those needed for subgrain nucleation.
Nucleation of microtubules from mitotic centrosomes is modulated by a phosphorylated epitope.
We have then no nucleation by the surface energy and a soup of matter.
Therefore, at high strain rates, the strength is determined by both the interatomic forces and by growth and nucleation of cavities.
Apparently, subtle variations in experimental conditions, such as the presence or absence of gentle agitation, can favor one nucleation event over others.
It should be pointed out that the mechanism of fragmentation is closely related to a nucleation phenomenon.
Such events can be handled by splitting the time interval into several parts (defined by time intervals between two nucleation or impingement events).
