Nanoindent of Copper

Nanoindent on deformed copper imaged with channeling contrast. Nanoindentation is a tool to measure the hardness very localised at a low force. Therefore surface defects such as scratches or, as can be seen here, the oxide layer might have an influence on the measurement.

Silver Clusters - Invisible Worlds

Silver clusters deposited by thermal evaporation onto self-assembled polystyrene nano-spheres (900 nm). Inspect F SEM FEG @ Nanofacility Piemonte INRIM. Self-assembled polystyrene nanospheres are used as masks for thin films and materials nanostructuration on large area. Maybe the subject doesn't match the topics of this year, but surely the title fits.
