Electrochemistry of aqueous amine systems
Aqueous amines solutions are widely used for the purification of various hydrocarbon mixtures of carbon- and sulfur-containing contaminations.
Corrosion of Nitinol
Nitinol is a shape-memory superelastic alloy widely used for various kinds of surgery. In particular, nitinol is one of the best materials for the production of intracoronary and brain arterial stents. The reliability of such a stent is a matter of life for a patient, because malfunctions of almost any kind may result in lethal damages.
Corrosion protection of magnesium alloys by PEO
(The project is performed in the cooperation with Prof. Michael Zinigrad)
Corrosion of magnesium alloys
The mechanism of corrosion processes in magnesium and its alloys is very complex and not completely understood, in spite of the large number of studies.

About the measurement of Tafel slopes
The Tafel plot which you can see in the picture below, is the most ideal polarization curve that can be. It was built with the data points computed by the Butler-Volmer equation for the following parameters: T = 298K, nc = na = 2 electrons, α = 0.5, io = 10-11 A. Any real polarization curve is 'worse' from the point of view of Tafel analysis.

A story of one false discovery
Two postgraduates (each in the framework of his/her research) had to compare corrosion rates of magnesium alloys in salt water measured by several techniques. Both obtained weird results, which can be summarized as follows:
