Often these compounds are synthesised at high temperatures so that the ionic mobility is high enough for the reactions to proceed.
where n, z, [mu] refer to the number of charge carriers, the ionic charge and the ionic mobility respectively.
Graphically,electrical resistivity readings are increase with a decreasing moisture content, reason being for a low soil moisture content there is less ionic mobility of electrons and hence higher the resistance.

The effect of increases of conductivity CMC-AC could be due to the enhancement of ionic mobility and the number of charge carrier or free ions [18, 22, 23].
Where q, [bar.[mu]], n, and E represent the electronic charge, the average ionic mobility, the density of the given ion, and the electric field respectively, and [v.sub.d] = [bar.[mu]]E denotes the drift velocity.
In (9)-(11) [[beta].sub.s] is ionic Stern-plane mobility, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] are ionic mobility of [Na.sup.+], ionic mobility of H+, ionic mobility of [Cl.sup.-], and ionic mobility of O[H.sup.-] in the solution, respectively, and [c.sub.Prot] is proton surface conductance.
The increase of amorphous area will improve ionic mobility and thus enhance the ionic conductivity of polymer electrolyte at room temperature.
where [phi] is the porosity of the material, z is the valence of the counter ions, and [beta] is the equivalent ionic mobility for the surface electrical conduction process ([m.sup.2]/s.V).
If the particles become even smaller, the inter-particulate voids can become so tight that contact between the electrolyte and electrode becomes restricted rather than expanded, hindering ionic mobility.
To tackle this problem, one of the best approaches is replacing of another metal/metal oxide into the ceria lattice thus facilitating the formation of composite oxides and replacement of cerium ions by cations of different size and/or charge modifies ionic mobility within the lattice ensuing in the formation of a defective fluorite structured solid solution.
