      abstract     = {The stability in ambient conditions of a scandium-based
                      NASICON material, Na3.4Sc2Si0.4P2.6O12, was investigated
                      using impedance spectroscopy, thermogravimetry/differential
                      scanning calorimetry (TG/DSC) and multinuclear magic angle
                      spinning nuclear magnetic resonance spectroscopy (MAS NMR).
                      The presence of H2O and CO2 in samples stored in ambient air
                      could be evidenced as well as its impact on the ionic
                      conductivity of the samples.The detected amounts of water
                      and CO2 in the samples had no influence on the measured
                      conductivities at room temperature, which confirmed the
                      absence of protonic conduction in hydrated samples. A loss
                      of conductivity during heating of hydrated samples was due
                      to a loss of contact between the ceramic and the electrode
                      used for the conductivity measurement.The recommendation for
                      handling of NASICON-type materials is therefore: samples
                      require storage in an Ar-filled glove box or in a dry
                      environment to avoid artefacts during high temperature
                      measurements. Nevertheless, the stability of the
                      NASICON-type materials is confirmed since their conductivity
                      is not affected by the moisture.},
