Study on electrical properties of Ni-doped SrTiO3 ceramics using impedance spectroscopy

Characterization of Physiological Glucose Concentration Using Electrical Impedance Spectroscopy

Non-invasive glucose monitoring is crucial for effective diabetes mellitus treatment while a sound correlation of a non-invasive parameter to glucose level variation is quite challenging. This paper presents characterization of glucose concentrations using Electrical Impedance Spectroscopy (EIS) in three different solutions: 1) 0.9% NaCl, 2) Saline (NaCl 1.3gm, KCl 0.75gm, Na3C6H5O7 1.45gm, D-g...

Electrical Characteristics of Biomodified Electrodes using Nonfaradaic Electrochemical Impedance Spectroscopy

We demonstrate a nonfaradaic electrochemical impedance spectroscopy measurement of biochemically modified gold plated electrodes using a two-electrode system. The absence of any redox indicator in the impedance measurements provide more precise and accurate characterization of the measured bioanalyte at molecular resolution. An equivalent electrical circuit of the electrodeelectrolyte interface...

Corrosion Study of Electroless Ni-P-W Coatings Using Electrochemical Impedance Spectroscopy

The present study investigates the significance of different coating process parameters on the corrosion behaviour of electrolessly deposited Ni-P-W coatings on mild steel substrate. The process parameters considered are concentration of nickel source, concentration of reducing agent, concentration of tungsten source and annealing temperature. The corrosion characteristic is evaluated by electr...

Dielectric spectra and electrical conduction in Fe-doped SrTiO3

The transport and dielectric properties of Sr0.97(Ti12xFex)O32d solid solutions have been investigated at temperatures 1.5 K<T<300 K and frequencies 20 Hz<n<1 MHz. Depending on x, suppression of the quantum-paraelectric background, dielectric anomalies associated with relaxational processes, variable-rangehopping conduction, and a sublinear power-law increase in the ac conductivity were observe...
