Vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. The effect of vanillin on the corrosion inhibition of carbon steel in 1.0 Mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques.The effect of temperature on the rate of corrosion in th...

In this paper, the effect of penicillin G drug as a green corrosion inhibitor on mild steel in 1.0 Mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The inhibition efficiencywas found to increase with increasing inhibitor concentration. Potentiodynamic polarizationmeasureme...

Corrosion of structural steel in an SRB containing environment for as long as 9 months, is studied using the Electrochemical Noise Analysis technique. The results show that the activity of the system, which was very low initially, started to increase after 6 months exposure to the environment. The power spectral density curves of the Electrochemical Potential Noise of the system, using the maxi...

The simultaneous fluctuations of potential noise and current noise between two nominally identical X-65 mild steel electrodes were recorded using a ZRA (Zero Resistance Ammeter) to monitor localized CO2 corrosion in CO2-saturated 1 wt % NaCl solution at 80C. Electrochemical noise (EN) was obtained from both 11.6 cm and 1 cm specimens to understand how the surface area affects EN signals. Linear...

We evaluate the RC-time of edge states capacitively coupled to a gate located away from a QPC which allows for partial transmission of an edge channel. At long times or low frequencies the RC-time governs the relaxation of charge and current and governs the fluctuations of the equilibrium electrostatic potential. The RC-time in mesoscopic structures is determined by an electrochemical capacitan...

y-tial intermetallic alloy have a good potential for use as biomaterial, due to its good corrosion resistance. in this paper, two fundamental electrochemical techniques namely electrochemical impedance spectroscopy and potentiodynamic anodic polarization were used to evaluate the corrosion performance of g-tial in ringer's solution. surface modification treatments were employed with the pu...

electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...

Three types of metallic nanostructures comprising niobium were investigated experimentally; in all three types, electric transport at very low temperatures was governed by Coulomb blockade effects. 1. Thin film strips of niobium could be tuned into resistor strips by an electrochemical anodisation process, using microfabricated masks and in situ resistance monitoring. These resistors showed a t...
