Electron Microscopy

_FFL4781

 

Scientific Leader: Prof. Vincenzo La Carrubba


The Lab isequipped with a JEOL JEMS-2100 microscope with a resolution of 1.4 Å (1.500.000) and can carry out tomographic, cryogenic, fluorescence and electronic diffraction measurements. The ultra-cryo-microtome allows to obtain samples with a thickness of few tens of nanometers. The laboratory is also equipped with a Scanning Electron Microscope (SEM) for morphological analyses of the surfaces. Thanks to EDX analysis, it is possible to identify the chemical composition of the sample surface and to provide informations about it (for example: polluting elements, corrosion, surface functionalization) etc. While, SEM carries out analyzes concerning microstructures, nanomaterials, surface treatments (nickel plating, chrome plating, Physical Vapor Deposition (PVD), Chemical Liquid Deposition (CLD) etc.), information about quenching and tempering, ballistic investigations, historical finds, biological tissues and asbestos fibers presence. The strong magnification coupled with the probe for chemical analysis allow to identify the triggering break-areas, the propagation lines of the crack and the areas with ductile or fragile morphology.
Services: various types of nanoparticles; historical parchments; carbon nanotubes and graphene; biological tissues; polymeric nanocomposites.
Fields of application: Biotechnology, Nanotechnology, Pharmaceutical, Agri-food, Cultural and Environmental Heritage.
