Enhancing pharmaceutical crystallization in a flow crystallizer with ultrasound: Anti-solvent crystallization Hasselt University KU Leuven
Continuous crystallization is a fast growing application domain in the pharmaceutical industry. Application of ultrasound has been proven to have positive effects like reduction in induction time and Metastable Zone Width (MSZW) in both batch and flow systems. Further understanding of flow-based sonocrystallization is required to achieve industrial level scale up. This work investigates the sonocrystallization of pharmaceutical compounds in a ...
Quantification of isothermal crystallization of polyamide 12: Modelling of crystallization kinetics and phase composition KU Leuven
© 2018 Elsevier Ltd The crystallization of Polyamide 12 (PA12) has been investigated using a new experimental setup which allows in-situ synchrotron Wide Angle X-ray Diffraction (WAXD) during Flash-DSC measurements. The experimental results are used to parameterize and validate a new numerical model to quantify the quiescent crystallization kinetics, under isothermal conditions, of the three important crystal structures of PA12, i.e. the, γ− α′− ...
Towards a new salt crystallisation test: comparison of salt contamination procedures Ghent University
The RILEM TC 271-ASC is currently developing a new ageing test to assess the resistance of porous building materials to salt crystallisation. The new test consists of two phases: salt accumulation and damage propagation. This paper focuses on the salt accumulation phase; this phase should promote salt crystallisation close to the evaporative surface of the substrates (common situation onsite) without leading to salt efflorescence or damage. ...
A multi-scale approach for the analysis of the mechanical effects of salt crystallisation in porous media Ghent University
First Investigations with the Protein Crystallisation Diagnostics Facility on board the International Space Station Vrije Universiteit Brussel
The Protein Crystallization Diagnostics Facility (PCDF) is an instrument developed by Astrium under an ESA contract to observe and study with advanced diagnostics nucleation and crystallisation processes of molecules from solutions in long duration microgravity on board the International Space Station.

A zeolite crystallisation model confirmed by in-situ observation KU Leuven
Probing nucleation and growth of porous crystals at a molecular level remains a cumbersome experimental endeavour due to the complexity of the synthesis media involved. In particular, the study of zeolite formation is hindered as these typically form in multiphasic synthesis media, which restricts experimental access to crystallisation processes. Zeolite formation from single phasic hydrated silicate ionic liquids (HSiL) opens new possibilities. ...
Towards a more effective and reliable salt crystallisation test for porous building materials University of Antwerp
The RILEM TC ASC-271 is designing a new procedure to assess the durability of porous building materials to salt crystallisation in the laboratory, consisting of a salt accumulation and a damage propagation phase. The salt accumulation consists of the capillary absorption of a salt solution followed by drying at low humidity to crystallize salts close to the evaporative surface without inducing damage. This was experimentally verified on ...
