Electrochemical Measurement of Corrosion

Corrosion, 1970
The results of electrochemical measurements on the corrosion of NiCrFe Alloy 600 and Zircaloy-2 in slightly alkaline lithiated water at 288 C (550 F) are presented. The study showed that, in the presence of dissolved hydrogen at the level of 35 Scc/kg-H2O, the electrochemical techniques could not be used to measure the corrosion rate of NiCrFe Alloy ...

Electrochemical measurement of phenothiazine-interacted DNA

Bioelectrochemistry, 2004
The amount of DNA was measured by using thioridazine, which would be attached to the DNA, as an electrochemical indicator. An indicator (thioridazine) solution, a test solution (DNA solution), and a poly-l-lysine solution were successively placed on a glassy carbon electrode, and the electrode was allowed to dry; DNA was immobilized on an electrode ...

Electrochemical Measurements of Blood Alcohol Levels

Nature, 1972
THE measurement of alcohol concentration in the breath is a more convenient and desirable method of enforcing the drinking and driving laws than the collection and analysis of blood samples. This method is valid because the alcohol concentration in alveolar air is proportional to the alcohol concentration in the blood; it is essential to ensure that ...

An Integrated Sensor for Electrochemical Measurements

IEEE Transactions on Biomedical Engineering, 1986
A method for the fabrication of a completely integrated solid-state electrochemical sensor which combines a minature liquid junction reference electrode with a CMOS ISFET is presented. The reference electrode is fabricated by preferentially etching silicon to form a porous silicon frit.

Combined Measurement of Electrochemical Noise and Electrochemical Impedance

CORROSION 2003, 2003
Abstract Electrochemical noise studies have been shown to be susceptible to asymmetry between the two electrodes that are normally used to measure the current noise, and there is consequently a need for noise monitoring methods that use a single electrode. In this paper such a method is presented.

Electrochemical Measurement Techniques

1989
Phase relations, thermodynamic and kinetic data are among the most fundamental materials parameters. They provide information about the existing stable phases, stability ranges, non-stoichiometries, atomic disorder, energies of formation, and electronic and ionic transport properties.

Organic Electrochemical Transistor to measure electrochemical potentials

2018
Organic Electrochemical Transistors (OECTs) have been proposed as low cost chemical sensors for the detection of several analytes thanks to their remarkable features such as signal amplification, the use of an easy and cheap readout electronics, low supply voltage (usually < 1 V), low power operation (< 100 μW), bio-compatibility, and, moreover, they ...

Electrochemical Measurement of Oxide Formation

Journal of The Electrochemical Society, 1958
Measurements have been made of the potential developed between a metal wire covered with its oxide and a platinum wire over which air or oxygen was passed. The electrolyte was the eutectic mixture of Li/sub 2/SO/sub 4/ and K/sub 2/SO/sub 4/, containing dissolved CaO and operated at various temperatures between 550 deg and75O deg C.

Electrochemical Corrosion-Rate Measurements

2000
Abstract This chapter discusses the principles and procedures of electrochemical measurements used to investigate corrosion behaviors. It begins by presenting a diagram of a basic potentiostatic circuit, which consists of a working electrode and an auxiliary or counter electrode suspended in an electrolytic solution.

Potentiostatic Measurements of Electrochemical Noise

CORROSION 2001, 2001
Abstract A new potentiostatic electrochemical noise (P-ECN) technique was recently developed to explore further improvement in corrosion monitoring methods. This technique has the ability to enhance monitoring of both general and localized corrosion.
