The effect of shear rate on polymer solution in the die does not reduce entirely to the intensification of bubble nucleation.
Peter Studer, program manager for VERISEQ Nucleation, said, "Until now, there has been no real commercially feasible way of achieving uniform ice nucleation, which resulted in prolonged operating cycles, reduced yield and overall uncertainty in scale-up.
Difference Between Homogeneous and Heterogeneous Nucleation S.
The opportunity to introduce nucleation really took it to the next level and we wanted to add a little heft for durability while we were at it.

AIST and Tohoku have clearly identified the initial nucleation followed by growth of quantum dot crystals, and moreover clarified the relationship between crystal structures in nucleation and growth, and the optical absorption spectra with the technique of computational chemistry.
PropaForm is a flee-flowing polypropylene-based masterbatch containing the Hyperform HPN68L nucleating agent, which is said to represent a new class of polypropylene nucleation that creates the highest quality parts at the fastest possible production rates.
The authors outline the mechanisms whereby secretion, active pumping, passive diffusion or gradient diffusion at the cellular level cause nucleation on particulates, on cell surfaces, or genetically programmed precipitation in organic matrices either on or within cells.
APPLICATION: It may be possible to develop crystal nucleation inhibitors or crystal growth inhibitors to prevent dicarbonate scaling.
