Synthesis and characterization of nano-objects

Synthesis and characterization of nano-objects:  IRAMIS has a capacity of synthesis of nano-objects by clean-rooms methods (MBE, lithography, laser ablation, ...) and by bottom-up chemical processes (solution processes, laser pyrolysis, CVD). This ability in nano-objects elaboration is accompanied by original research to functionalize them or implement them, to get nanostructured macroscopic materials or functional objects.

These synthesis are accompanied by numerous works of fine characterization of the interactions between atoms or molecules, involved in the development of nano-objects and nanomaterials or related to their properties.

For the required applications, with the objective of achieving the design of functional and well characterized components, this knowledge makes it possible to orient by application of controlled constraints, the associations between the elementary components, to obtain a range of "nano-objects" : complex molecules, nanoparticles, carbon nanotubes, graphene, micellar structures or colloidal, self-assembled compounds, solid nanostructured, or functionalized surfaces...

Research topics
To get objects with original features, making molecular materials is addressed by assembling building blocks, as atoms, simple or complex molecules or nanostructures (carbon nanotubes, and graphene sheets in particular) on metallic, inorganic or organic supports, glass ...
Self-assembly is generally the result of an energy balance between bulk energy terms and terms resulting of interfacial energies.
In many liquid or solid materials of our everyday life matter appears as highly divided. The precise organization of the finely divided components from the microscopic to the macroscopic scale has a huge implication on the properties of these materials.
The development of nanotechnology based nowdays on the assembly (or even self-assembly) of building blocks that are nanoparticles.
In very many situations, whether it be in fluids or materials for every day use, or in biological systems, matter is present in a highly dispersed form. It follows an extraordinary range of behaviour due to structural combinations, from the molecular to the mesoscopic and macroscopic scale.
In this domain, the field of study of DRECAM covers the molecule to the controlled assembly of molecules.
