Electrochemical impedance spectroscopy of the LixMn2O4 interface with natural brine
(Elsevier Science Sa, 2018-05)
The LiMn2O4-Polypyrrole electrochemical cell has been shown to extract LiCl from natural brine at low voltage with high selectivity, low energy consumption (5?10 Wh·mol−1) and good stability. The intercalation/de-intercalation ...
Electronic tongue for simultaneous detection of endotoxins and other contaminants of microbiological origin
(Elsevier Advanced Technology, 2010-07)
Endotoxins, also referred to as pyrogens, are lipopolysaccharides (LPS) present in the outer membrane of Gram-negative bacteria, and represent one of the most dangerous microbiological contaminants in water for hemodialysis ...
Study of the electrode polarization resistance of cobaltites with high Ba content as cathode for IT-SOFC
(Electrochemical Society, 2017-05)
The phase relationships and the electrochemical behavior of cobaltites with high content of Ba, such as, La1-xBaxCoO3-δ with x = 0.5, 0.7 and 1.0, Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) and BaCo0.7Fe0.2Nb0.1O3-δ (BCFN), were ...
Effect of cobalt-doped electrolyte on the electrochemical performance of LSCFO/CGO interfaces
(IOP Publishing, 2016-06)
In this work, we have studied La0.4Sr0.6Co0.8Fe0.2O3-δ/Ce0.8Gd0.2O2-δ/La0.4Sr0.6Co0.8Fe0.2O3-δ symmetrical cells containing Ce0.8Gd0.2O2-δ electrolytes synthetized with and without the addition of cobalt as sintering aid. ...
Application of EIS and SEM to evaluate the influence of pigment shape and content in ZRP formulations on the corrosion prevention of naval steel
(Pergamon-Elsevier Science Ltd, 2002-06)
The effects of pigment volume concentration and morphology of zinc particles employed in the formulation of zinc rich paints (ZRP) suitable for the corrosion protection of naval steel in sea water, have been investigated ...
Enhanced electrocatalytic behaviour of gold electrodes modified with ZnO nanoparticles through organophosphonate chemistry
(Elsevier Science, 2020-01)
Stable immobilization and homogenous distribution of ZnO nanostructures on solid substrates can play a fundamental role in developing nanostructured biosensing devices. In this work we studied how phosphonic acid-terminated ...
Degradation of oxygen reduction reaction kinetics in porous La0.6Sr0.4Co0.2Fe0.8O3-δ cathodes due to aging-induced changes in surface chemistry
(Elsevier Science, 2017-01-01)
The modification of surface composition after long-term operation is one of the most reported degradation mechanisms of (La,Sr)(Co,Fe)O3-δ (LSCFO) cathodes for Solid Oxide Fuel Cells (SOFCs). Nevertheless, its effect on ...
Oxide/hydroxide films on tin. II: Characterization of the anodic growth in alkaline solutions
(Elsevier Science Sa, 2008)
Electrochemical characterization of AISI 316L stainless steel in contact with simulated body fluid under infection conditions
(Springer, 2008-05)
Titanium and cobalt alloys, as well as some stainless steels, are among the most frequently used materials in orthopaedic surgery. In industrialized countries, stainless steel devices are used only for temporary implants ...
