Résumé:
Why is nanoscience relevant in energy? Many effects important for energy happen at the
nanoscale. In solar cells, for instance, photons can free electrons from a material, which can
then flow as an electric current; the chemical reactions inside a battery or fuel cell release
electrons which then move through an external circuit; or the role of catalysts in a plethora of
chemical reactions. These are just a few examples where nanoscale engineering can
significantly improve the efficiency of the underlying processes
