    • 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 ...

    • 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 ...

    • Physicochemical, structural, and mechanical properties of Si3N4 films annealed in O2 

      Aguzzoli, Cesar; Marin, Cristiane; Figueroa, Carlos Alejandro; Soares, Gabriel Vieira; Baumvol, Israel Jacob Rabin (2010) [Artigo de periódico]
      The physicochemical, structural, and mechanical properties of silicon nitride films deposited by radio frequency reactive magnetron sputtering were investigated before and after thermal annealing in 18O2. As-deposited films ...
