Various mechanisms have been proposed to explain the nonphotochemical laser-induced nucleation (NPLIN). Identifying the dominant mechanism requires addressing a large set of experimental parameters with a statistically significant number of samples, forced by the stochastic na ...

The principal objective of the research focuses on the intensification of the batch and continuous crystallization processes through enhanced nucleation control, proper plug flow conditions in continuous tubular crystallizers and development of advanced image analysis based PAT t ...

In this study, an in situ imaging system has been analysed to characterize the crystal size, the shape and the number of particles during a continuous crystallization process in a Continuous Oscillatory Baffled Crystallizer (COBC). Two image analysis approaches were examined f ...

The control of nucleation in crystallization processes is a challenging task due to the often lacking knowledge on the process kinetics. Inflexible (predetermined) control strategies fail to grow the nucleated crystals to the desired quality because of the variability in the p ...

The use of a continuously operated oscillatory flow baffled crystallizer (COBC) has been promoted as a promising alternative crystallizer design for continuous crystallization because of the claim, based on dispersion of liquid, that plug flow can be achieved. Plug flow can lead ...

Nucleation is the initial step for the creation of new crystalline phase. A precise control over nucleation and its kinetics is important for both research and industries. Thus, alternative methods are sought after to extend the toolbox for controlling nucleation. In the 1990's, ...
