  • The properties of nanoparticles are strongly dependent on size and shape.

  • It is therefore important to synthesize these materials using a methodology that is able to finely control these structural parameters and the corresponding polydispersity degree.

  • In this course we focus on synthetic aspects for the design of nanostructured materials.

  • We describe different approaches including both the bottom-up(includes both chemical and physical methods) and the top-down methods(mainly physical methods) for the synthesis of nanostructured materials.

  • The course will then focus on different type of nanostructures with a special emphasis on carbon nanotubes(CNT), metal and metal oxide nanoparticles, core-shell nanostructures and self assembly of these nanostructures.

  • The dependence of various properties (dielectric, magnetic and optical) with size will be discussed.
