NANO OBJETS ET NANO MATERIAUX Matriaux nanoporeux et nano objets PYT

Nanoporous materials: we have shown that the desalloying  of ultrathin layers of gold and copper leads to the formation of nanoporous gold membranes that are easily transferable to any type of support. The team is working on their use in applications of transparent conductors for desalloying  and SERS sensors.
Nano-objects: The team has been developing approaches for the synthesis of nano-objects (nanowires and nanotubes) for several years on direct PVD deposition on template substrates combined with various treatments such as desalloying or the Kirkendall effect  or the conversion. The studies are focused on the understanding of physicochemical mechanisms involved at nanometric scales, on the other hand on the use of these mechanisms for shaping controlled objects at the nanometric scale.
