Waterborne Epoxy based coatings were prepared by using a water-borne epoxy resin and a suitable hardener. The formulation and optimization procedure were carried out on the bases of experimental designs by the mixture design technique in which the important paint properties are modeled by using special cubic model. The corrosion behavior of these coatings was investigated using electrochemical ...

aisi 304l austenitic stainless steel with different grain sizes of 0.5 -12 μm was obtained through the martensiticprocess. corrosion behavior of different samples was investigated in a 0.5m hcl solution using open circuitpotential, potentiodynamic polarization and electrochemical impedance spectroscopy tests. also, the correlationbetween the grain size and pitting corrosion resistance was asses...

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 ...

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...

electrochemical properties of various rock-shaped-cuo/graphite (g) composites and monoclinic structure cuo nanoparticles as the cathode versus a zinc plate as the anode in a 4m naoh electrolyte were elucidated by electrochemical impedance spectroscopy (eis) and chronopotentiometry (cp) in a two electrode configuration cell. various values of g 9, 16 and 28 wt% were prepared and studied as catho...

Electrical impedance of biological matter is known as electrical bioimpedance or simply as bio-impedance. Bio-impedance devices are of great value for monitoring the pathological and physiological status of biological tissues in clinical and home environments. The technological progress in instrumentation has significantly contributed to the progress that has been observed during the last past ...
