Free Nanoparticles

The understanding of nanoparticle properties when they exist as free isolated objects is a crucial point for the assessment of a bottom-up approach to nanostructured materials growth like our Supersonic Cluster Beam Deposition technique. Our group has a long-standing tradition in the development of gas-phase- clusters and nanoparticles characterization methods and in the original design and fabrication of dedicated instruments and apparatus. Aerodynamic-separation techniques are used for nano-object manipulation in terms of classification and concentration of nanoparticles into high-intensity and low-divergence molecular beams under High- or Ultra High- Vacuum conditions; these beams have been demonstrated to be suitable means for the application of advanced characterization methods like core-level photoemission spectroscopy and related techniques based on the coincidence detection of charged-products from highly diluted samples.
