Joint Workshop on Nucleation
Joint Workshop on Nucleation
** This event took place already **
On Monday 1 April 2019, the 4TU.Research Centre High-Tech Materials (4TU.HTM) and the Materials Innovation Institute (M2i) were organizing a Joint Workshop on Nucleation in Utrecht (De Witte Vosch). Some pictures can be found here.
Introduction by prof.dr.ir. Jilt Sietsma, scientific director of 4TU.HTM

Nucleation is among the most fascinating processes in materials science, whereas it is crucial for the production and behaviour of all materials. Taking place at the smallest length and time scales, experimental observation is challenging. Theoretical frameworks have been proposed through recent decades, but predictive power is limited for many aspects of nucleation.
This workshop aims to bring scientists and industrial partners with interest and expertise on nucleation throughout the different types of materials and processes together for an exchange of ideas and observations, looking for the crucial characteristics of nucleation.

Title: Nucleation of Solidification as an Athermal Process
Textbook treatments of nucleation normally consider it to be a stochastic process: through a series of bimolecular reactions, critical nuclei eventually arise. For both homogeneous and heterogeneous nucleation, the kinetics is commonly considered in terms of the rate of generation of critical nuclei on holding at a fixed temperature. In the practical processing of materials, heterogeneous nucleation is much more likely, and ... [continue reading, Pdf file].
Prof. Greer's (short bio, Pdf file) research interests are: metallic glasses and crystal nucleation, grain refinement in casting, and chalcogenide thin films for phase-change data storage.
