Titania nanotubes (TNT) prepared by anodization of Ti foils were used for water splitting in a standalone cell. The concentration polarization between the anode side (1M NaOH) and cathode side (0.5 M H2SO4) ensured that the water splitting reaction could take place with no external bias and separate H2 and O2 evolution could be achieved. The destructi...

The electrochemical behavior of nickel, Inconel 600, Incoloy 800 and 316 stainless steel electrodes in different concentration of NaOH solution was investigated using the cyclic voltammetry technique (CV). All the curves in the anodic branch of the CV are characterized by anodic dissolution peak (A), passive region (B), anodic dissolution peak (C) before oxygen evolution. In the case of the cat...

Interfacial reactions of cytochrome c3 at a graphite electrode were studied in a neutral medium by means of the differential pulse and cyclic voltammetry. It was found that ferricytochrome c3 yielded three cathodic peaks G, d i and Cm at potentials of —0.3 to —0.5 V (vs. Ag/AgCl reference electrode) on the voltammograms. Upon anodic polarization this protein yielded two anodic peaks Ai and An a...

By means of linear polarization, Tafel polarization and galvanostatic discharge methods, the kinetic properties of MlNi4.3ÿXCoXAl0.7 (X=0.0, 0.3, 0.5, 0.7, 0.9, 1.1 and 1.3) hydride electrodes, including high rate dischargeability HRD, exchange current density I0, limiting current density IL, the symmetry factor b, and the apparent di€usion coecient of hydrogen in the a phase Da have been stud...

The corrosion inhibition of ST37 Carbon Steel in 1.0 M HCl by aquatic extract of coconut has been studied as a possible source of green inhibitor using the potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The aquatic extract of coconut have many advantages over classical techniques of sample preparation of plant gums (such as drying and solvent reflux).Pol...

Tarnish and Corrosion behavior of three Commercial dental amalgams namely Am.1, Am.2, Am.3, have been investigated by utilizing in vitro tests. The corrosion and/or dissolution rate of the three dental amalgams were studied in 0.9 wt% NaCl Solution, artificial saliva and Ringers solution. Potentiodynamic polarization technique was employed to study cathodic and anodic polarization behavior, fro...
