    • Aluminum mobility and interfacial segregation in fully silicided gate contacts 

      Pezzi, Rafael Peretti; Copel, Matthew; Cabral Junior, C.; Baumvol, Israel Jacob Rabin (2005) [Artigo de periódico]
      The mobility of aluminum implanted as a dopant of fully silicided nickel for advanced metal gates has been investigated following rapid thermal annealing at temperatures ranging from 160 to 700 °C. Resonant nuclear reaction ...

    • Clean synthesis of biocarbon-supported Ni@Pd core–shell particles via hydrothermal method for direct ethanol fuel cell anode application 

      Silva, Elen Almeida Leal da; Cuña Suárez, Andrés; Reyes Plascencia, Carmina; Radtke, Claudio; Tancredi, Néstor; Malfatti, Célia de Fraga (2020) [Artigo de periódico]
      Direct ethanol fuel cells (DEFCs) are devices for clean and sustainable energy production, where the generation of electrical energy occurs as a result of the anodic ethanol oxidation reaction (EOR). One of the main ...

    • Magnetism in dilute magnetic oxide thin films based on SnO/sub 2/ 

      Fitzgerald, C.B.; Venkatesan, M.; Dorneles, Lucio Strazzabosco; Gunning, R.; Stamenov, Plamen; Coey, John Michael Douglas; Stampe, P.A.; Kennedy, R.J.; Moreira, Eduardo Ceretta; Sias, Uilson Schwantz (2006) [Artigo de periódico]
      Thin films of SnO2 prepared by pulsed-laser deposition on R-cut sapphire substrates exhibit ferromagnetic properties at room temperature when they are doped with Cr, Mn, Fe, Co, or Ni, but not with other 3d cations. ...

    • Propagation of transverse domain walls in homogeneous magnetic nanowires 

      Allende Prieto, Sebastián; Altbir Drullinsky, Dora; Torres, Evy Augusto Salcedo; Bahiana, Monica Pereira; Sinnecker, João Paulo (2008) [Artigo de periódico]
      The field driven nucleation and propagation of transverse domain walls in a uniform Ni nanowire is examined by means of Monte Carlo simulations combined with a scaling technique. Simulations show a nonlinear behavior ...

    • Synthesis of magnetic nanoparticles functionalized with histidine and nickel to immobilize His-tagged enzymes using β-galactosidase as a model 

      Andrade, Bruna Coelho de; Gennari, Adriano; Renard, Gaby; Da Rolt Nervis, Brenda; Benvenutti, Edilson Valmir; Costa, Tania Maria Haas; Nicolodi, Sabrina; Silveira, Nádya Pesce da; Chies, Jocelei Maria; Volpato, Giandra; Souza, Claucia Fernanda Volken de (2021) [Artigo de periódico]
      The aim of this study was to synthesize iron magnetic nanoparticles functionalized with histidine and nickel (Fe3O4-His-Ni) to be used as support materials for oriented immobilization of His-tagged recombinant enzymes of ...
