    • Detrapping of vacancies at in/sup 111/ in quenched silver 

      Arias, C. Alonso; Behar, Moni; Filevich, A.; García Bermúdez, Gerardo Jose; Savino, E.J.; Livi, Rogerio Pohlmann; Zawislak, Fernando Claudio (1981) [Artigo de periódico]
      The isothermal recovery of a quenched Ag foil doped with 111 ln has been studied through the time-differential perturbed-angular-correlation technique. A nearest-neighbor-vacancy configuration has produced a quadrupole ...

    • Direct evidence for projectile charge-ctate dependent crater formation due to fast ions 

      Papaleo, Ricardo Meurer; Silva, Marcos Rodrigo; Leal, Rafael Gustavo Torres; Grande, Pedro Luis; Roth, Melanie; Schattat, Beate; Schiwietz, Gregor (2008) [Artigo de periódico]
      We report on craters formed by individual 3 MeV/u Au qini⁺ ions of selected incident charge states qini penetrating thin layers of poly(methyl methacrylate). Holes and raised regions are formed around the region of the ...

    • In-situ transmission electron microscopy growth of nanoparticles under extreme conditions 

      Luce, Flavia Piegas; Oliviero, Erwan Marie Hubert; Azevedo, Gustavo de Medeiros; Baptista, Daniel Lorscheitter; Fichtner, Paulo Fernando Papaleo (2016) [Artigo de periódico]
      The formation and time resolved behavior of individual Pb nanoparticles embedded in silica have been studied by in-situ transmission electron microscopy observations at high temperatures (400–1100 C) and under 200 keV ...

    • Structural, electronic, and magnetic properties of tetragonal Mn/sub3−x/Ga : experiments and first-principles calculations 

      Winterlik, Jürgen; Balke, Benjamin; Fecher, Gerhard H.; Felser, Claudia; Alves, Maria do Carmo Martins; Bernardi, Fabiano; Morais, Jonder (2008) [Artigo de periódico]
      This work reports on the electronic, magnetic, and structural properties of the binary intermetallic compounds Mn3−xGa. The tetragonal DO22 phase of the Mn3−xGa series, with x varying from 0 to 1.0 in steps of x=0.1, was ...

    • Testing a fault tolerant mixed-signal design under TID and heavy ions 

      González Aguilera, Carlos Julio; Machado, Diego do Nascimento; Vaz, Rafael Galhardo; Vilas Bôas, Alexis Cristiano; Gonçalez, Odair Lelis; Puchner, Helmut K.; Added, Nemitala; Macchione, Eduardo; Aguiar, Vitor Ângelo Paulino de; Kastensmidt, Fernanda Gusmão de Lima; Medina, Nilberto Hedar; Guazzelli, Marcilei Aparecida; Balen, Tiago Roberto (2021) [Artigo de periódico]
      This work presents results of three distinctradiation tests performed upon a fault tolerant data acqui-sition system comprising a design diversity redundancytechnique. The first and second experiments are Total Ion-izing ...
