High performance water-based paints with non-toxic anticorrosive pigments
(Elsevier Science Sa, 2002-12)
Legal restrictions have impelled the replacement of solvent-borne resins and of toxic chromates and lead-bearing pigments in the elaboration of paints. Water-based anticorrosive paints have come a long way to improve their ...
MOF@PEDOT Composite Films for Impedimetric Pesticide Sensors
(Wiley, 2019-12)
Due to its deleterious effects on health, development of new methods for detection and removal of pesticide residues in primary and derived agricultural products is a research topic of great importance. Among them, imazalil ...
Electrical response of bivalent modifier cations into a vanadium-tellurite glassy matrix
(Elsevier Science, 2014-02-22)
In this work, we suggest an explanation of the electrical conductivity behavior of tellurite glassy systems modified with barium when transition metal oxides (V2O5-MoO3) present in the glassy matrix are replaced progressively ...
High-Pressure Performance of Mixed-Conducting Oxygen Electrodes: Effect of Interstitial versus Vacancy Conductivity
(Electrochemical Society, 2016-10-06)
Electrochemical response was measured as a function of oxygen pressure pO2 up to 10 bar for four different mixed-conducting oxygen electrode materials, the oxygen-vacancy-conducting perovskites (Sm0.5Sr0.5)CoO3 (SSC) and ...
Anti-corrosion performance of Cr+6-free passivating layers applied on electrogalvanized steel
(Scientific Research, 2010-03)
Hexavalent chromium-based passivation treatments have been successfully used as promoters of conversion coatings for many years. Their effectiveness is without question although there are many problems with regard to their ...
Formulation and assessment of Wash-Primer containing lanthanum tannate for steel temporary protection
(Springer, 2018-04)
Tannins are polyphenols synthesized by plants and useful for the coating industry as corrosion inhibitors. In addition, lanthanum salts have a great inhibitory effect on steel corrosion. The aim of this study was to obtain ...
Triplex systems: Accelerated and outdoor tests
(Wiley VCH Verlag, 2019-03)
The protective paint/galvanized steel system is called duplex and it is claimed that protects steel from corrosion synergistically. The triplex system adds a pretreatment between the paint and the substrate in order to ...
Electron transfer across anodic films formed on tin in carbonate-bicarbonate buffer solution
(Pergamon-Elsevier Science Ltd, 2005-01)
Impedance and steady-state data were recorded in order to study the kinetics of electron transfer between passive tin electrodes and an electrolytic solution containing the K3Fe(CN)6-K 4Fe(CN)6 redox couple. Film thickness ...
A review article about the deactivation of poly(o-aminophenol) film electrodes employing Impedance Spectroscopy and Surface Resistance
(Bentham Science Publishers, 2018-04)
Objective: Storage time without use (STWU) in the supporting electrolyte solution for time periods beyond 30 hours deactivates poly(o-aminophenol) (POAP) films.
Observations: Deactivated POAP films exhibit a lower ...
Sol-gel synthesis and electrical characterization of doped-carbon decorated mixed conductor ceramics
(Elsevier Science, 2019-02)
New mixed composite conductors of compositions: Li3V2−x [Cu]x (PO4)3/C and Li3V2−x [Nb]x(PO4)3/C (x = 0.1; 0.2 and 0.3) have been synthesized by the sol-gel method using Citric and Oxalic acids as a primary carbon source ...
