Corrosion rate determination of austenic steels in calcium hypochlorite solutions

open access: yesZaštita Materijala, 2016
This paper presents the results of testing the corrosion resistance of austenitic chromium-nickel steel X6 CrNiTi 18-10 and X6 CrNiNb 18-10 in solutions of calcium hypochlorite. For the tests were used potentiodynamic measurement methods.

Stability of vector bundles on curves and degenerations

open access: yes, 2014
We observe that if we are interested primarily in degeneration arguments, there is a weaker notion of (semi)stability for vector bundles on reducible curves, which is sufficient for many applications, and does not depend on a choice of polarization.

Role of Some Plating Parameters in the Properties of Ni-P/Al2O3 Nanocomposite Coatings on Mg alloy

open access: yesInternational Journal of Electrochemical Science, 2016
Electroless Ni-P/Al2O3 nanocomposite coatings on AZ91D magnesium alloy have been deposited by incorporating nanoalumina particles into Ni-P alloy matrix to stimulate the wear and corrosion resistance of the substrate.

Robustness of the magnetoresistance of nanoparticle arrays

open access: yes, 2010
Recent work has found that the interplay between spin accumulation and Coulomb blockade in nanoparticle arrays results in peaky I-V and tunneling magnetoresistance (TMR) curves and in huge values of the TMR. We analyze how these effects are influenced by

Electrochemical behavior of carbon steel under a continuous kerosene flow in two different kind of sections

open access: yesInternational Journal of Electrochemical Science, 2018
This work studies the electrochemical behavior of carbon steel under a continuous kerosene flow in two different kinds of sections: a linear section and a 90-degree horizontal elbow section.

Effect of Hypochlorite Ions on Corrosion of Cu-Ni Alloys Immersed in Seawater at Turbulent Flow Conditions

open access: yesInternational Journal of Electrochemical Science, 2018
A corrosion study of Cu-Ni (90-10) alloy was carried out in natural seawater adding several concentrations of an oxidant biocide (hypochlorite-based biocide).

Rank-Dependent Measures of Bi-Polarization and Marginal Tax Reforms [PDF]

open access: yes
In this paper, we investigate a dual class of bi-polarization indices, namely rank-dependent bi-polarization indices. We show that these indices may be characterized with the generalized positional transfer sensitivity property.
