& abstract submission






The workshop dedicated to "Mechanical properties of core-shell nanostructures" will take place in Toulouse at CEMES. The workshop will begin on October 1st, 9h, and will finish on October 2, 15h.

In multiphase nanostructures, the presence of interfaces between a so called “core” and a so called “shell”, and more generally between two phases (“Janus” morphology…), is likely to modify the mechanical properties compared to individual behavior of each component, either in bulk state or as single phase nanostructure. Nanoparticles, nanowires, nanodisks, nanotubes and any other nano-objects exhibiting core-shell, multi-shell or multiphase morphologies are concerned. They can be made of semiconductors, metals, oxides, organic material... Hybrid systems are obviously also considered.

Presentations and discussions on experimental, theoretical and modelling issues are welcome. A non-exhaustive list of topics to be addressed during the workshop is given below:

  • Mechanical properties (lattice vibrations, elastic properties, piezoelectricity, surface stress….) of the core-shell structure compared to individual properties of each phase

  • Investigation of buried interfaces in core-shell structures (atomic concentration profile, presence of defects, …)

  • Internal or external stress transmission through the interface between the core and the shell

  • Stability and equilibrium shape compared to bulk or single phases of each component; metastable shapes induced by controlled elaboration

  • Use of mechanical properties to (multi)-functionalize a core-shell nanostructure: stress engineering, response to an external solicitation, change in reactivity due to surface stress…

Some abstracts will be selected for oral presentation (20 +10 mn). Others contributions will be presented in a poster session. The number of participants will be limited to favor a workshop atmosphere where discussions keep an informal character.
