• First-principles calculation of the structure and elastic properties of a 3D-polymerized fullerite 

      Perottoni, Claudio Antonio; Jornada, Joao Alziro Herz da (2002) [Artigo de periódico]
      In this paper we present results obtained from first-principles calculations concerning the crystal structure and elastic properties of a three-dimensional-polymerized fullerite. The orthorhombic structure we studied was ...
    • 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) [Artigo de periódico]
      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 ...
    • Mechanical properties of highly oriented FeSe0.5Te0.5 superconductor 

      Pimentel Junior, Jorge Luiz; Pureur Neto, Paulo; Lopes, Cristiano Santos; Serbena, Francisco Carlos; Foerster, Carlos Eugenio; Silva, Simone Aparecida da; Jurelo, Alcione Roberto; Chinelatto, Adilson Luiz (2012) [Artigo de periódico]
      We have synthesized highly oriented samples of the superconducting compound FeSe0.5Te0.5 and investigated its mechanical properties. These samples were characterized by scanning electron microscopy (SEM) with energy-dispersive ...
