Using electrochemical impedance spectroscopy of salicylate anion selective electrode: simulation for behavior of electrode

In this paper, the behavior of the salicylate anion-selective electrode was studied using the electrochemical impedance spectroscopy technique. Considering the diagram of the charge transfer resistance and -logarithm of the double layer capacitance versus -logarithm of the concentration, linear range concentration increased to 1.0×10^{-8}-1.0×10^{-1} M and 1.0×10^{-9}-1.0×10^{-1} M, respectivel...

Impedance/Modulus Analysis of Sol-gel BaxSr1−xTiO3 Thin Films

Perovskite-structure-type sol-gel barium-strontium-titanate (BST) thin films with molar formula BaxSr1−xTiO3 (x = 0.5, 0.6, 0.7, and 0.8) have been successfully fabricated as Al/BST/Pt capacitors. In order to study the role of the grain size in the conduction mechanisms, we present atomic force microscopy (AFM) results. The impedance and the electric modulus of BaxSr1−xTiO3 thin films have been...

Single Crystal by Impedance Spectroscopy

Bi 4 Ge 3 O 12 (bismuth germanate – BGO) single crystals were produced by the Czochralski technique and their electrical and dielectric properties were investigated by impedance spectroscopy. The isothermal ac measurements were performed for temperatures from room temperature up to 750 °C, but only the data taken above 500 °C presented a complete semicircle in the complex impedance diagrams. Ex...

Portable Analyzer for Impedance Spectroscopy

− The paper presents an impedance analyzer designed for impedance spectroscopy of objects located in the field. The use of the specialized microsystem AD5933 was assumed. The analysis and tests of the microsystem in the configuration proposed by the manufacturer showed the limitations having meaningful influence on the impedance measurement accuracy. In order to eliminate disadvantages of the m...
