Luca Davico

I, Luca Davico, passed Master of Chemical Engineering and Sustainable Processes from Politecnico di Torino (Italy) in 2013. I performed my master thesis on "Mathematical modeling for the evaluation of the particle size distribution of polymer powder under different conditions" at the SABIC Technology and Innovation center in Geleen (The Netherlands). Since July 2013, I am a PhD student at the Ruhr-Universit├Ąt Bochum (Germany) on "Diffusion Stable Microcapsule" with Prof. Dr.-Ing. Eckhard Weidner, Prof. Dr.-Ing. Marcus Petermann and Dr. Sabine Kareth in the DoHip project.

 

Topic

The aim of this project is to obtain diffusion stable microcapsules, i.e. microcapsules where the release of the core material due to transport phenomena is slowed down.
A capsule is obtained when a substance, called core material, (for example a flavor or a drug) is entrapped into another substance, called shell material. Micro is referred to the dimensions of the capsules. The advantages of encapsulation can be the enhanced resistance of the core material against atmospheric effects or the possibility to control the release of the entrapped substance when it is required. Once the substance is entrapped, it will eventually leave the capsule when the shell material breaks or due to transport phenomena.
The microcapsules will be produced using high pressure processes, e.g. PGSS (Particles from Gas Saturated Solutions) or MDT (Melt Dispersion Technique). Different parameters, like temperature, pressure, residence time, type and quantity of emulsifiers, will be analyzed to find out their effect on the stability of the microcapsule. Collecting all these information will generate knowledge and understanding for the process and it will help to generate the know-how to produce tailor-made microcapsules with specific required characteristics.
