The Nanotechnology laboratory is equipped for the characterization and manipulation of materials at nanoscale by employing SPM techniques (AFM and SNOM), particle size measurement, micro-Raman scattering, nanocalorimetry and nanoindentation. This laboratory allows a comprehensive study of the properties of nanostructured materials, including size, mechanical, thermal, optical, structural, and electrical properties.
