Voorbeelden van nucleation

• 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).

• In this way, the nucleation procedure we follow goes through a natural temporal and thermal evolution.

• While it is possible that the coalified surfaces acted as nucleation sites, the possibility that the spheres are organosilicates cannot be discounted.

• The capsule of host tissue surrounding them did not provide any barrier to ice nucleation.

• Here nucleation is the opposite of interface disappearance.

• However, little information is available on the microtubule nucleation ability of centrosomes of either male or female origin in maturing or pre-activated porcine oocytes.

• We assume that the volume fraction of crystals upon bubble nucleation is sufficiently high that the bubbles are prevented from subsequent buoyant motion.

• It is an up-to-date and comprehensive compilation of all aspects of igneous petrology, ranging from the nucleation and growth of crystals to magma genesis.
