Reus, M.A. (author)
In this dissertation crystallization and microencapsulation processes are used to produce multicomponent particulate products with different functionalities (improved stability, controlled release, protection from environment, etc.) and their performance is assessed. Additionally, the interactions between the components in the processes are...

Soare, A. (author)
The scope of this thesis is to study new methods for control of the most important phenomena in crystallization processes: nucleation and crystal growth. In order to achieve this, novel process equipment, which utilize alternative driving forces, were developed. It was proven that primary nucleation for solution crystallization can be controlled...

Heat and mass transfers are coupled processes, also in nucleation. In principle, a nucleating cluster would have a different temperature compared to the surrounding supersaturated old phase because of the heat release involved with attaching molecules to the cluster. In turn a difference in temperature across the cluster surface is a driving...

Landheer, H. (author)
The nucleation mechanisms during solid-state phase transformations in polycrystalline materials are still not completely understood. The nucleation stage has a strong influence on the overall evolution of phase transformations, which determines the final microstructure and thereby the properties of the material. The understanding of grain...

Jiang, S. (author)
Polymorphism is frequently encountered in many pharmaceutical, chemical, and food products. Polymorphs have the same chemical composition but different crystal structures, and therefore differ in their physicochemical properties such as stability, solubility, and bioavailability. These property differences can influence the product performance....

A new method is proposed for the determination of the stationary one-component nucleation rate J with the help of data for the growth probability P2 of a dimer which is the smallest cluster of the nucleating phase. The method is based on an exact formula relating J and P2, and is readily applicable to computer simulations of nucleation. Using...

Exact and approximate general expressions for the growth and decay probabilities of a cluster in one-component nucleation are given. A method is proposed for a model-independent determination of the nucleus size with the help of data for the dependence of the cluster growth probability on the cluster size. Monte Carlo simulation data for the...
