Presentation of GIMD department

This research department focuses on the generation and behaviour of interfaces in various processes, multi-scale and multi-physics modelling in dispersed media (colloids, particles, crystals, emulsions) and membrane processes. The main applications are in chemical, healthcare, agronomy, food and environment sectors.

The overall objectives of GIMD department :

  • Physical or physicochemical interactions involved in the solid-liquid, liquid-liquid and gas-liquid interfaces in processes in dispersed or membrane-bound media form the basis for the work carried out in this department: design and behaviour of interfaces are
    explored by linking the processes on the microscopic scale with macro properties of the media and/or of the processes.
  • Research carried out in the GIMD department focuses on the design and control of interfaces (gas-liquid, liquid-liquid or more frequently solid-liquid) and analyses phenomena taking place on or through them as well as phenomena trying to modify them. These interfaces are found in a wide variety of systems such as dispersions of particles and crystals, emulsions, and membrane systems. Different types of processes are directly concerned by these activities :
    • crystallisation, grinding, chemical-vapour-deposition (MCVD) or sol-gel deposit techniques, able to produce particles or materials
    • division and design processes of complex systems such as membrane filtration, hydraulic separation and the development of structured deposits
    • Contactors, liquid-liquid and liquid-solid separators. This research is carried out at different scales :
    • Local level: for a better understanding of the fundamental mechanisms
    • Global level: to optimize the conditions of a process, to look for new ways to generate or to use interfaces.
