Electrical Conduction in (Na0.5Bi0.5)1−xBaxTiO3 (0≤x≤1) Ceramic by Complex Impedance/Modulus Spectroscopy

Equivalent Electrical Circuit Modeling of Ceramic-Based Microbial Fuel Cells Using the Electrochemical Impedance Spectroscopy (EIS) Analysis

The effect of the thickness of ceramic membrane on the productivity of microbial fuel cells (MFCs) was investigated with respect to the electricity generation and domestic wastewater treatment efficiencies. The thickest ceramic membrane (9 mm) gained the highest coulombic efficiency (27.58±4.2 %), voltage (681.15±33.1 mV), and current and power densities (447.11±21.37 mA/m2, 63.82±10.42 mW/m2) ...

Electrical Conduction in Dilute Amalgams.

The modem theory of electrical conduction in metals, according to which the metal is dissociated to give a positive ion of low mobility, which is characteristic of the metal, and a negative carrier of high mobility, which is common to all metals and presumably to be identified with the electron, has given rise to certain misgivings, despite the complete analogy between this theory and the accep...

Electrical Conduction in Nonlinear Composites

Composite systems constitute a large class of naturally occurring or artificially synthesized disordered systems [1]. The systems are microscopically inhomogeneous and disordered but look homogeneous on the macroscopic scale. From the tunnelling electron micrographs (TEM) of such a composite material it can be seen that the typical dimension (ξ) of metallic islands embedded in the insulating ma...

Electrical conduction by interface states in semiconductor heterojunctions

Electrical conduction in semiconductor heterojunctions containing defect states in the interface region is studied. As the classical drift-diffusion mechanism cannot in any case explain electrical conduction in semiconductor heterojunctions, tunnelling involving interface states is often considered as a possible conduction path. A theoretical treatment is made where defect states in the interfa...
