Evaluation of the electrochemical behavior of carbon paste electrode (CPE) with chalcopyrite (CuFeS2) in the presence of ferrous ions
(Trans Tech Publications Ltd, 2013-01-01)
In this work we present an electrochemical study using carbon paste electrode (CPE) with CuFeS2 in solutions with different concentrations of Fe2+ ions in order to evaluate the possible interaction between these ions and ...
Development of an amperometric sensor for potassium ions
(2008-12-01)
Hollandite-type manganese oxides are nanofibrous crystals with sub-nanometer open tunnels that provide a unique property for sensing applications. Sensor based on hollandite-type manganese oxide was investigated for ...
Plasma immersion ion implantation on 15-5PH stainless steel: Influence on fatigue strength and wear resistance
(2017-05-31)
Surface improvement in steels is of great interest for applications in industry. The aim of this investigation is to study the effect of nitrogen ion implantation on the axial fatigue strength and wear resistance of 15-5 ...

Caracterização morfológica da corrosão por pite da liga AL2024 em soluções contendo cloretos e molibdatos
(2003-12-01)
A very new method application for digital image processing and analysis to classify shape and evaluate size and morphology parameters of pit corrosion is used in this paper. This method seems to be very effective to analysis ...
Improved Langevin approach to spinodal decomposition in the chiral transition
(2006-02-11)
We use an improved Langevin description that incorporates both additive and multiplicative noise terms to study the dynamics of phase ordering. We perform real-time lattice simulations to investigate the role played by ...
