Effect of NaCl on the Corrosion of Cold Rolled Steel in Peracetic Acid Solution

open access: yesInternational Journal of Electrochemical Science, 2012
Effect of sodium chloride (NaCl) on the corrosion of cold rolled steel (CRS) in peracetic acid solution (PAA) was investigated by potentiodynamic polarization curves, cyclic polarization curves and electrochemical impedance spectroscopy (EIS) at 0 °C, 10

Fourier-Mukai transforms of curves and principal polarizations [PDF]

open access: yes, 2007
Given a Fourier-Mukai transform $\Phi$ between the bounded derived categories of two smooth projective curves, we verifiy that the induced map between the Jacobian varieties preserves the principal polarization if and only if $\Phi$ is an equivalence ...

Electrochemical Impedance Spectroscopy for the Measurement of the Corrosion Rate of Magnesium Alloys: Brief Review and Challenges

open access: yesMetals, 2020
From a technological point of view, measurement of the corrosion rate of magnesium (Mg) and its alloys is critical for lifetime predictions of Mg-based structures and for comparative assessments of their corrosion protection ability.

Inversion of polarimetric data from eclipsing binaries [PDF]

open access: yes, 1998
We describe a method for determining the limb polarization and limb darkening of stars in eclipsing binary systems, by inverting photometric and polarimetric light curves. Because of the ill-conditioning of the problem, we use the Backus-Gilbert method

Observation of two relaxation mechanisms in transport between spin split edge states at high imbalance [PDF]

open access: yes, 2003
Using a quasi-Corbino geometry to directly study electron transport between spin-split edge states, we find a pronounced hysteresis in the I-V curves, originating from slow relaxation processes.

The Effect of Heat Treatment on Corrosion Resistance of 6061 Aluminum Alloy

open access: yesInternational Journal of Electrochemical Science, 2016
In this paper, the corrosion resistance in 3.5% NaCl solution of 6061 aluminum alloys after different heat treatment is investigated by slow strain rate equipment, polarization curves and impedance, combining scanning electron microscopy.

Electrochemical Performance of Fe-Al intermetallic alloys with addition of Li, Ni and Ce in NaVO3 at 700°C

open access: yesInternational Journal of Electrochemical Science, 2013
Potentiodynamic polarization curves and polarization resistance measurements were used to study the hot corrosion behavior of two intermetallic compounds, i.e., FeAl and Fe3Al with minor additions of Ni, Ce and Li exposed in a NaVO3 salt at 700°C.

Polars of real singular curves [PDF]

open access: yes, 2008
Polar varieties have in recent years been used by Bank, Giusti, Heintz, Mbakop, and Pardo, and by Safey El Din and Schost, to find efficient procedures for determining points on all real components of a given non-singular algebraic variety. In this note we review the classical notion of polars and polar varieties, as well as the construction of what we

Comparison of the influence of nitrate ions on the electrochemical behaviour of iron and carbon steels in sulphate solutions [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
The effect of nitrate ions on the electrochemical behaviour of iron (ferrite) and two carbon steels (martensite and pearlite) in sulphate solutions of different pH values was investigated by cyclic voltammetry polarization and electrochemical impedance ...
