Effect of Al substitution on the structural, electric and impedance behavior of cobalt ferrite

Vacuum, 2019
Cobalt ferrite nanoparticles doped with Al ions, Co1-x AlxFe2O4 (x = 0, 0.1, 0.3 and 0.5) were prepared by sol-gel method. An attempt is made to understand if and how the Al substitution affect the structural and electrical properties of cobalt ferrite ...

Identification of characteristic time constants in the initial dynamic response of electric double layer capacitors from high-frequency electrochemical impedance

Journal of Power Sources, 2018
The impedances of several electric double layer capacitors are analysed at high frequencies by using the Randles equivalent electric circuit with the semi-infinite Warburg impedance.

Access impedance in Brazilian in-home, broadband and low-voltage electric power grids

Electric power systems research, 2019
This paper focuses on the measurement, characterization and modeling of the access impedance of the Brazilian in-home, broadband and low-voltage electric power grids when the frequency band between 2 and 500 Hz is taken into account.

Electrical Impedance Tomography

2017
Presently, non-invasive techniques are in vogue and preferred standard clinical approach because of its limitless advantages in monitoring real time phenomenon occurring within our human body without much interference. Many techniques such as ultrasound, magnetocardiography, CT scan, MRI etc., are used for real time monitoring but are generally not ...

Electrical impedance tomography

Inverse Problems, 2002
Updated (up to 2002, 153 references) theoretical and numerical studies of the inverse problem for the continuum model of EIT which seeks the admittivity \((\gamma(x)= \sigma(x)+ i\omega\varepsilon(x))\) inside a body \(\Omega\) from the knowledge of the Dirichlet to Neumann (DtN) (or the Neumann to Dirichlet (NtD)) map at the boundary \(\partial\Omega\)

Electrical Impedance Spectroscopy

2018
This chapter gives some background on impedance spectroscopy and tissue impedance but also about the instrumentation used for measuring transfer impedance of a biological material under study. The instrumentation concerned here is the current source for applying a current to tissue and the differential amplifier for measuring the resultant voltage.
