The electrochemical behavior of the oxide layers on two metal-metal glassy alloys, Fe78Co9Cr10Mo2Al1 (VX9)and Fe49Co49V2 (VX50) (at.%), were studied using electrochemical techniques including electrochemical frequency modulation (EFM), electrochemical impedance spectroscopy (EIS) and cyclic polarization (CP) measurements. The morphology and composition of the alloy surfaces were investigated us...

   In this work, the effect of annealing temperature on the microstructure, morphology, and optical properties of Cu-doped nanostructured MnO2 thin films were studied. The thin films were prepared by sol-gel spin-coating technique on glass substrates and annealed in the air ambient at 300, 350, 400 and 450 °C temperatures. The structural, morphological and optical properties of t...

In this paper, polymer-based nanocomposites powder were applied on the surface of plain carbon steel by electrostatic device and then were cured by microwave. The effect of adding nanoparticles on the corrosion resistance properties of the coatings was investigated by Electrochemical Impedance Spectroscopy and immersion test in 3.5 NaCl solution. Coatings structure and morphology of nanoparticl...

Abstract The development of eco-friendly materials for advanced applications is highly demanded. current study focuses on the preparation conductive membranes based tricarboxylic cellulose (TCC) loaded with cubic bismuth sodium titanate (BNKT) nanoceramics. FTIR, SEM, and EDX analyses confirm presence BNKT membranes. electrical response cellulose/xBNKT (x = 5, 10, 15, 20% wt/wt) membrane invest...

Common impedance methods in tissues or cell suspensions as well as dielectric particle spectroscopy by ACelectrokinetics are based on the impedance properties of the different constituents of tissue, particles or cells and the suspensionmedia.Whereas impedancemethods detect the frequency dependence of the direct electric response of a suspension, electrokinetic methods investigate the frequency...
