    • Mecanismos eletroquímicos nos processos de descarga do sistema PbO2/H2SO4 

      Freitas, Heverson Renan (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 17/11/2017)
      The goal of this work was to seek a mechanistic and morphological understanding of the discharge process of lead-acid batteries’ positive plates, which exhibits a complex porous structure. Due to this fact, nonporous ...

    • Estudo mecanístico de reações de estado sólido: o caso do sistema Pb/PbSO4/Na2SO4 

      Freitas, Heverson Renan de (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 21/11/2012)
      In this work, the growth and reduction of PbSO4 in Na2SO4 solution under transient conditions was characterized. A novel methodology for the working-electrode surface preparation before stabilization enhanced the voltametric ...

    • Carbonos no material ativo de baterias chumbo-ácido 

      Tsurumaki, Maumi (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação de Mestrado Profissional em Química - PPGQ, Câmpus São Carlos, 12/08/2015)
      Different types of carbon has been studied globally as additives for negative active material of lead acid batteries aiming to improve the charge acceptance and the cycling endurance of the batteries when applied in PSoC ...
