Síntese, caracterização e testes eletroquímicos de dióxido de manganês nanométrico como material de eletrodo de supercapacitores
(Universidade Federal de São Carlos, 2018-08-01)
Manganese dioxide was synthesized by a microwave-hydrothermal method using alternative, unprecedented and completely soluble reagents. For such, potassium permanganate and acetone were dissolved in different proportions ...
Simulação do crescimento de filmes sobre metais. O caso voltamétrico
(Universidade Federal de São Carlos, 2008-07-02)
In this work the anodic film growth on metals has been studied, under voltammetric conditions by simulation. It was supposed that: a) the films are ultrathin, i.e., the concentration gradient contributions for the ionic ...
Investigação do mecanismo de formação de filmes porosos de TiO2 obtidos por anodização galvanostática
(Universidade Federal de São Carlos, 2011-10-20)
In this work the experimental and theoretical aspects of the growth of titanium dioxide obtained by galvanostatic anodization were studied. The _lms were prepared by galvanostatic anodization of titanium, where the curve ...
Estudo das propriedades eletroquímicas e magnéticas do polipirrol
(Universidade Federal de São Carlos, 2010-11-22)
In this work the electrochemical degradation of polypyrrole films was studied by means of an applied overpotential and the magnetic properties of polypyrrole pellets, when these were modified by the incorporation of metallic ...
Estudo das eletrodeposições de lítio e gálio sobre Au(111) e HOPG utilizando líquido iônico como eletrólito
(Universidade Federal de São Carlos, 2009-03-06)
In the present work, the electrodepositions of lithium and gallium on Au(111) and HOPG (highly oriented phyrolytic graphite) were studied using ionic liquids (ILs) as electrolytes and employing the following techniques: ...
