    • Cratering and plastic deformation in polystyrene induced by MeV heavy ions : dependence on the molecular weight 

      Farenzena, Lucio Sartori; Livi, Rogerio Pohlmann; Araujo, Marco Aurelio de; García Bermúdez, Gerardo Jose; Papaleo, Ricardo Meurer (2001) [Artigo de periódico]
      Cratering and plastic deformation induced by individual MeV ions on the surface of polystyrene thin films of different molecular weights (Mw) (from 3250 to 2 X 10⁷u) are investigated using scanning force microscopy. 20 ...

    • Interferometric monitoring of dip coating 

      Michels, Alexandre Fassini; Menegotto, Thiago; Horowitz, Flavio (2004) [Artigo de periódico]
      Dip-coated films, which are widely used in the coating industry, are usually measured by capacitive methods with micrometric precision. For the first time to our knowledge, we have applied an interferometric determination ...

    • Optically monitored dip coating as a contactless viscometry method for liquid films 

      Michels, Alexandre Fassini; Menegotto, Thiago; Horowitz, Flavio (2005) [Artigo de periódico]
      Real-time interferometric monitoring of the dip coating process is applied to the study of properties of flowing liquids. Nonvolatile Newtonian oils are considered, allowing validity of a simple model after the steady state ...

    • Time-resolved optical Kerr-effect investigation on CS2/polystyrene mixtures 

      Heisler, Ismael Andre; Correia, Ricardo Rego Bordalo; Buckup, Tiago; Cunha, Silvio Luiz Souza; Silveira, Nádya Pesce da (2005) [Artigo de periódico]
      The relaxation dynamics of carbon disulfide are investigated in mixtures with polystyrene (PS) using the time-resolved optical heterodyne-detected optical Kerr effect (OHD-OKE). The data are analyzed using both the ...
