According to the classical nucleation theory, the nucleation of austenite transformation is represented by the site saturation nucleation model.
The predictive capability of nanoscale modeling approaches has grown rapidly in the last few years and there have been a number of notable discoveries relevant to understanding the nucleation mechanism in ice.
There are some dispersive chain segments of PE embedded in the molecular chain of PP-B which play a role of heterogeneous nucleation agent in the crystallization process, resulting in higher nucleation density of PP-B than that of HPP.
There have been many studies on ice nucleation of subcooled melt, mostly motivated by the formation of snow crystals, and commonly revolving around the dynamics of crystal growth from the gaseous phase.
Raman signals from the nucleation side of D1 and D2 samples (figure 2) show that the D2 sample has slightly higher stress and its peak is broaden.
In addition to the dependence of the nucleation efficiency of these four modes on temperature and relative humidity, there is also a dependence on the physical and chemical properties of the surfaces of the ice nuclei that facilitates ice embryo formation (Pruppacher and Klett, 1997; DeMott et al.
According to Wim Van de Velde, global marketing manager, Polyethylene Nucleation, Milliken Chemical: "Building on our global leadership in nucleation agents for polypropylene, Milliken is now also focused on polyethylene to meet a longstanding need for processing and performance enhancements.
In addition, the scientists used a refrigerated water-ethylene glycol bath to confirm ice nucleation activity.
