Research Interests
Before I joined the Chemical Engineering Department of the UD, my research interests concerned the study of dynamic and static properties of colloidal dispersions submitted to various contrains (shear-flow, geometrical confinement...). That's the reason why the publications and presentations listed below are not related to the nano-science project. I hope it will change soon...

In the framework of nano-science project, we intend to use Molecular Dynamics simulations to predict the diffusive motion of penetrants through nanostructured membranes. In particular, we focus on the diffusivity and selectivity properties of nanoporous carbons (NPC's) with regard to a O2/N2 penetrant. The current work in progress concerns the conception of a proper simulation method taking into account the actual topology of NPC's with respect to chemical constraints.
