GIMD – Interface and Particle Interaction Engineering
Crystallization Engineering and Solid and Particles Processes



Crystallization and precipitation processes in complex media: generation and formulation of crystals with controlled properties. Multiscale approach and methodology for controlling the quality and the end-use properties of the crystals or nanostructured particles, by acting on the design and on the operating conditions of the process. Experimental and modelling approaches.

– Thermodynamic of solid-liquid systems at equilibrium and out of equilibrium

– Local study of nucleation and crystal growth mechanisms in dynamic.

– Influence of additives and impurities on crystallization kinetics.

– Aggregation and characterization of precipitated nanoparticle suspensions under flow

– Innovative crystallization processes for wastewater treatment, energy saving or recycling.

Key words:  chemical engineering/industrial crystallization/nucleation/crystal growth/ aggregation



Application & Teaching

Research interest:

  • Process-product interactions for controlling solid end-use properties (purity, polymorphism, crystal size distribution, morphology)
  • Processes of spherical crystallization
  • Nucleation and crystal growth kinetics study in controlled conditions
  • Nucleation and growth in microfluidic systems
  • Processes for generation, stabilization and characterization of nanoparticles
  • From batch to continuous crystallization processes

Applications: generation of pharmaceutical active particles/wastewater treatment by precipitation/material for energy /recycling / urban mining
