study the fabrication and characterization of hafnium nanoparticles and hafnium nanoparticlethinfilms. Hafnium nanoparticles were grown in vacuum by magnetron-sputtering inert-gas condensation. The as deposited nanoparticles have a hexagonal close-packed crystal structure, they possess truncated
hexagonal biprism shape and are prone to surface oxidation when exposed to ambient air forming core–shell Hf/HfO2 structures. Hafnium nanoparticlethinfilms were formed through energetic nanoparticle deposition. This technique allows for the control of the energy of charged nanoparticles during vacuum
deposition. The structural and nanomechanical properties of the nanoparticlethinfilms were investigated as a function of the kinetic energy of the nanoparticles. The results reveal that by proper adjustment of the nanoparticle energy, hexagonal close-packed porous nanoparticlethinfilms with good

gives an unprecedented opportunity to control the size and the shape of bimetallic nanoparticles without changing their composition. The mechanisms involved in the complete reshaping of the nanoparticlethinfilms are discussed and it is also shown that order-disorder phase transformations occur under
