Silicate Ions as Corrosion Inhibitors for Carbon Steel in Chloride-Contaminated Concrete Pore Simulating Solutions
(NACE International, 2020-10)
Silicate ions were tested as corrosion inhibitors for construction steel using concrete pore simulating solutions contaminated with chloride ions. The results are compared to those from solutions with no silicate and with ...
Carbon steel passivity examined in alkaline solutions: the effect of chloride and nitrite ions
(Pergamon-Elsevier Science Ltd, 2008-06-09)
The effect of chloride and nitrite ions on the passivity of steel in alkaline solutions was investigated. Four nitrite dosages were tested, resulting in various nitrite/chloride ratios. The behavior of steel was evaluated ...
A full-atom multiscale modelling for sodium chloride diffusion in anion exchange membranes
(Elsevier Science, 2021-11)
A novel full-atom multiscale method, combining different computational approaches and aimed to describe diffusion of multiple ions in anion exchange membranes (AEM), is presented. The method is used to evaluate diffusion ...
Nitrite corrosion inhibition in chloride-rich electrolytes correlated to the electrical properties of surface films on carbon steel
(Elsevier, 2019-12)
The electronic properties and the composition of surface films grown in pore simulating solutions are studied using various electrochemical and surface techniques and then correlated to the inhibiting efficiency of nitrite ...
Evaluation and comparison of traditional methods and Electron Probe Micro Analysis (EPMA) to determine the chloride ingress perpendicular to cracks in self-healing concrete
(Elsevier, 2019-12)
The appearance of cracks in reinforced concrete structures accelerates the penetration of aggressive substances such as chloride ions into the concrete matrix. This leads to durability problems due to the accelerated onset ...

Sustainable selective extraction of lithium chloride from natural brine using a Li1-xMn2O4 ion pump
(Electrochemical Society, 2018-10)
The spontaneous electrochemical extraction of lithium chloride from natural brine of high altitude salt flats in Northwest Argentina and recovery in a dilute electrolyte is demonstrated in two experiments: i) a highly ...
Low potential pitting corrosion of Ni-Cr-Fe alloys in chloride plus thiosulfate solutions: determination of potential and concentration boundaries
(NACE International, 2020-06)
Low potential pitting corrosion (LPPC) of alloys 690 and 800 (UNS N06690 and N08800) was studied in neutral solutions, containing chloride ion from 0.1 to 1 M and thiosulfate ion from 5x10-5 to 10-3 M. LPPC occurred close ...
Electrochemical behaviour of steel in mortar and in simulated pore solutions: Analogies and differences
(Pergamon-Elsevier Science Ltd, 2016-10)
On evaluating the corrosion resistance of concrete, it is frequent to performelectrochemical tests in the so called simulated pore solutions (SPS) to replace tests performed in concrete specimens. Besides, to study the ...
Copper Deposition from Chloride-Containing Aqueous Solutions: Catalysis and the Role of the Water Structure
(American Chemical Society, 2021-01)
The formation of complexes and the effect of a water network close to the surface on the copper deposition are investigated by means of molecular dynamics simulations. Surprisingly, the presence of chloride has a little ...
