However, such small metal clusters can only be generated by gas-phase techniques, typically in a ligand-free environment as naked clusters. A controlled

• study of 3-D metal clusters as catalysts in CNT growth was reported in [8], however, no CNT growth was studied therein; CNT growth derived from nm-sized, ligand-stabilized mixed metal clusters as precatalysts was reported in [9].) Non-agglomerated naked iron clusters of 0.6–0.9 nm size were generated

For instance, nitric oxide decomposition on thin film aluminum oxide preferentially takes place at the APDBs [52]. It has been predicted by means of DFT calculations [47] that

A major issue is that nanoparticles are usually moved individually so that the AFM tip has to be properly positioned with
