Estudo eletroquímico da calcopirita em solução salina ácida utilizada em biolixiviação
(Universidade Estadual Paulista (Unesp), 2016-10-27)
A calcopirita (CuFeS2) é o sulfeto de cobre mais abundante na natureza e pertence ao grupo mais explorado de minerais de cobre, representando cerca de 70% do total de cobre disponível. O objetivo deste trabalho foi estudar ...
Electrodeposition and characterization of thin selenium films modified with lead ad-atoms
(ELSEVIER SCIENCE BV, 2008)
The deposition and characterization of Se films doped with Pb underpotentially deposited (UPD) ad-atoms was studied in this work. The employed experimental techniques were cyclic voltammetry, chronoamperometry, electrochemical ...
Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
Electrochemical study of hydroxychloroquine and its determination in plaquenil by differential pulse voltammetry
(Elsevier B.V., 2003-06-01)
Hydroxychloroquine (HCQ) is a halogenated aminoquinoline that presents wide biological activity, often being used as an antimalarial drug. The electrochemical reduction of HCQ was investigated by cyclic voltammetry and ...

Methanol Oxidation in Alkaline Medium Using PtIn/C Electrocatalysts
(Springer, 2016-11-01)
Pt/C and PtIn/C with atomic ratios of 90:10, 70:30, and 50:50 were investigated for methanol electro-oxidation in alkaline media by using cyclic voltammetry (CV), chronoamperometry (CA), and direct methanol alkaline fuel ...
