We work on the fabrication by Spark discharge aerosol generation of a large variety of nanoparticles (Pt, Au, Cu, CuO, WO₃, TiO_2, etc). We deposit them in range of substrates such as carbon cloths, for the fabrication of advanced nanomaterials that are aimed at a range of applications, such as H storage, plasmonic sensors etc. We characterize them with a wide range of techniques and especially Electron microscopy for the optimisation of their structure and their functional  properties.
