Nucleation in emulsion polymerization : steps towards a non-micellar nucleation theory
… understanding of the mechanism of particle nucleation in emulsion polymerization has been one of the most challenging issues in heterophase polymerization research. Within this work a comprehensive experimental study of particle nucleation in emulsion polymerization of styrene at 70 °C and …

Competitive Nucleation in Nanoclusters
Nucleation is the primary mechanism by which systems change phase and it plays a major role in the formation of new materials in nature and industrially. In particular, experiments and molecular dynamic simulations have shown that nanoclusters, at the same initial conditions, freeze to different …

Kinetics of Nesquehonite Nucleation
<p>During the nucleation of mineral crystals, the particles (atoms and molecules) will be ordered in a crystal lattice and mineral surfaces will develop. The interfacial energy plays important roles in mineral nucleation. The surface energy can be influenced by many factors including temperature, …

Nucleation of Cavities in Gels
… of stress due to the swelling may lead to the nucleation and growth of cavities within the gel, which is likely to cause the debonding of the material from the support it is attached to. In this dissertation, we focus on the cavitation in a gel occupying a spherical domain, subject to either …

On Protein Crystal Nucleation Precursors
… numerous disease pathologies. Although the nucleation process is critical in determining the nucleation rate and polymorph of the crystal, it is a poorly understood phenomenon. Here, we present the effects of shear flow on protein pre-nucleation clusters, which grow in size but dramatically …

Heterogeneous nucleation in polymer crystallization
… boron nitride, saccharin and sorbitol on the nucleation and crystallisation of PP, PE, PB, POM, PHB, PET and Nylon 66 has been investigated by DSC, light microscopy and electron microscopy. The effectiveness of the nucleating agent has been evaluated by the study of the interfacial layer …

Nucleation seeding in metakaolin geopolymers
… of the two binder materials. Understanding nucleation kinetics in cement binders have led to the development of different admixtures such as accelerators and retarders and it is believed that a clear picture of the nucleation step in geopolymer formation will aid the development of …

Inorganic Nanoparticle Nucleation on Polymer Matrices
… process: a period of slow, continuous nucleation followed by rapid, autocatalytic growth. The reaction kinetics for this autocatalytic process is also reported.;PAA was crosslinked both chemically and physically to 3 biopolymers; ELP, an elastin like peptide, cotton fabrics, and calcium …

Nucleation and growth of pharmaceutical crystals
Investigating nucleation, crystal growth and solid-state transformations at the nanoscale are of significant interest, as more complex routes have roused questions about the classical view of these processes. This thesis reports the characterisation of prenucleation clusters in olanzapine (OZPN) …

Amyloid Fibril Nucleation In Reverse Micelles
The 40-residue amyloid beta protein (Abeta) is the unstructured cleavage product of a common membrane protein that is produced in large quantities, but normally cleared from the brain before it exerts any apparent toxicity. Under some conditions, however, it undergoes a conformational change and …

Understanding Heterogeneous Nucleation Mechanisms in Polyolefins
… Experimental methods to study heterogeneous nucleation are often plagued with confounding factors that lead to uncertainty in the measured kinetics and thermodynamics of nucleation. Molecular simulations have recently showed promise to investigate the nano time- and length- scales associated …
