In this paper, we report the measurements of impedance spectroscopy for a new olivine-type lithium deficiency Li0.9□0.1NiV0.5P0.5O4 compound. It was synthesized by the conventional solid-state technique. All the X-ray diffraction peaks of the compound are indexed, and it is found that the sample is well crystallized in orthorhombic olivine structure belonging to the space group Pnma. Conductivi...

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 ...

Abstrac t -Two commercial two-phase digital AC voltage sources, WW2572A from Tabor Electronics and SYS-2722 from Audio Precision, were tested for their potential use in impedance comparator bridges. The mutual relative stability of magnitudes and phase shifts of their output voltages were evaluated. Results of relative amplitude and phase shift stability measurements prove that it is possible t...

The nonlinear dependence on applied ac field (bv) or current (iv) of the microwave ~ac! impedance Rv 1iXv of both short and long Josephson junctions is calculated under a variety of excitation conditions. The dependence on the junction width is studied, for both field symmetric ~current antisymmetric! and field antisymmetric ~current symmetric! excitation configurations. The resistance shows st...
