    • Hardness and elasticity in cubic ruthenium dioxide 

      Leger, Jean Michel; Djemia, P.; Ganot, F.; Haines, Julian; Pereira, Altair Soria; Jornada, Joao Alziro Herz da (2001) [Journal article]
      The Knoop hardness of the highly incompressible cubic phase of ruthenium dioxide was found to be 19–20 GPa from indentation tests. This value scales well with the shear modulus approximated by the elastic constant C44 of ...
