WebThe present work was undertaken to establish rates of primary nucleation for isotactic polypropylene and to put forth a modified classical model for the secondary nucleation process in isotactic polypropylene systems. Web11 Jun 2013 · Our results show that once a small but critical concentration of amyloid fibrils has accumulated, the toxic oligomeric species are predominantly formed from monomeric peptide molecules through a fibril-catalyzed secondary nucleation reaction, rather than through a classical mechanism of homogeneous primary nucleation.

Web17 Apr 2024 · Thus, secondary nucleation generates fibrils that have the morphology dictated by the buffer conditions, as if they were formed by primary nucleation. Why I chose this preprint The spreading of α-synuclein pathology in a prion-like fashion throughout the brain, and even starting from the gut (1), has been studied extensively in recent years (see … Webnucleation, the initial process that occurs in the formation of a crystal from a solution, a liquid, or a vapour, in which a small number of ions, atoms, or molecules become arranged in a pattern characteristic of a crystalline solid, forming a site upon which additional particles are deposited as the crystal grows. Nucleation processes are classed as heterogeneous … michael jackson black or white signification
