Micro and Nanomechanics Laboratory – NANOMEC

Micro and Nanomechanics Laboratory - NANOMEC

The Micro and Nanomechanics Laboratory (NANOMEC) is located at IMDEA Materials Institute and is organized into two fundamental units:

  • Materials Microstructural Characterization Unit

Materials Mechanical Characterization Unit:

  • Nanoindentation instrumented by two equipments:
    • Hysitron Triboindener TI950, nanoindenter with multiple loading heads optimized for different applications (maximum loading resolution, 1 nN), dynamic measurements, scratch and wear tests, SPM imaging obtention, and elastic modulus maps with the indentation tip itself.
