Clarifying agents, a special type of nucleating agent, are able to reduce crystal size through creation of "extra" nucleation sites upon which spherulites can grow [6, 10-13].
Second, we will use our unique capacity to perform dynamic micropatterning, to add or remove actin nucleation sites in real time, in order to investigate the ability of dynamic networks to adapt to changes and the role of coupled network dynamics in this emergent property.
In this study, due to the addition of Mn, the lamellar spacing of pearlite is reduced, which means that more austenite nucleation sites are provided.
Discriminating, for example, the role of bonding from crystallographic match and determining the structure of active nucleation sites and then assessing their importance in different atmospheric conditions requires a systematic, multipronged, and concerted approach.
The method, called DCM2, employs an advanced plasma-based ion implantation process that enhances the carbon saturation at the surface of the cutting tool, creating an embedded zone of nucleation sites primed for subsequent diamond growth.
These nucleation sites are stereocomplex crystallites with 31 helix in conformation and surrounded by a PLLA crystalline phase.
This disruption enables the inorganic matter to break down while eliminating the nucleation sites that provide attachment spots for biofilms.
The early work quoted above considered that nucleation sites were uniform randomly located in space, or more precisely, that nuclei were located in space according to a homogeneous Poisson point process.
In nature, the extent of supercooling required for ice formation is modified by the presence of solid particles in the water, which serve as nucleation sites for the initial formation of ice crystals known as frazil ice (Martin, 1981).
The nucleation sites are intrinsically there at the material interfaces.
The effects of premature nucleation sites inherent on contacting surface can be eliminated either by superheating liquid droplet in an immiscible liquid of high boiling point or by heating the contacting surface with the test liquid rapidly so that the heat transfer to the liquid exceeds the latent heat of vaporization of the liquid (known as pulse heating method with fine platinum wires) as described by Skripov (1974).
