Estudo do processo de eletrodeposição e caracterização de ligas de Sn-Zn
(Universidade Federal de São Carlos, 2009-05-27)
This study evaluated the electrodeposition processes of Sn, Zn and Sn-Zn alloy in the absence and presence of tartaric acid as complexing agent. Initially all the systems studied were evaluated by Cyclic Voltammetry to ...
Estudos microgravimétricos da deposição de cobre sobre eletrodos de cromo passivado.
(Universidade Federal de São Carlos, 2002-11-29)
Recently were obtained in our laboratory results indicating that Cu deposition on
Cr2O3 happens in two steps: at the first one, there is the deposition of an amount
smaller than one Cu monolayer, and at the second one there ...
Caracterização dos processos de eletrodo em compostos do tipo LixNiyCo1-yO2 utilizando técnicas de impedância
(Universidade Federal de São Carlos, 2005-09-09)
In this work a qualitative study was carried out, using electrochemical impedance spectroscopy (EIS), exchanging cobalt by nickel in LixNiyCo1-yO2 compound synthetized by method of the polymeric precursor (Pechini s Method). ...
Obtenção e caracterização eletroquímica do compósito polipirrol
(Universidade Federal de São Carlos, 2002-04-15)
This study was carried out to investigate the electrochemical
preparation of a composite polypyrrole / cobalt, as well as your characterization
physical-chemistry. The composite was electropolymerized on a platinum
substrate ...
