    • Agglomeration defects on irradiated carbon nanotubes 

      Moura, Cassio Stein; Balzaretti, Naira Maria; Amaral, Livio; Lacerda, Rodrigo Gribel; Pimenta, Marcos A. (2012) [Artigo de periódico]
      Aligned carbon nanotubes (CNT) were irradiated in the longitudinal and perpendicular directions, with low energy carbon and helium ions in order to observe the formation of defects in the atomic structure. Analysis through ...

    • Dimensional crossover in magnetic warwickites 

      Guimaraes, Renato Bastos; Fernandes, Joao Carlos; Continentino, Mucio Amado; Borges, Hortencio A.; Moura, Cassio Stein; Cunha, Joao Batista Marimon da; Santos, Carlos Alberto dos (1997) [Artigo de periódico]
      We present an investigation of the magnetic properties of a series of warwickites with different transition metals. These materials are characterized by one-dimensional structures called ribbons where the transition metals ...

    • Few layer reduced graphene oxide : evaluation of the best experimental conditions for easy production 

      Pavoski, Giovani; Maraschin, Thuany Garcia; Fim, Fabiana de Carvalho; Balzaretti, Naira Maria; Galland, Griselda Ligia Barrera; Moura, Cassio Stein; Basso, Nara Regina de Souza (2017) [Artigo de periódico]
      This work aimed to produce graphene oxide with few graphene layers, a low number of defects, good conductivity and reasonable amount of oxygen, adequate for use as filler in polymeric composites. Two starting materials ...
