In its most fundamental forms, the Nernst equation for an electrode is written as:
Figure 5 shows that when increasing the stirring speeds the extraction efficiency increases and this can further be explained by the fact that stirring the solution increases the contact between the preextracted analytes in the extracting solvent and the fibre [26], as well as preventing the formation of a Nernst diffusion layer which reduces the concentration gradient at the interface of the fibre and the bulk aqueous solution.
The linear relationship between the concentration ratio of [I.sub.2]/KI solution and the ORP value was obtained through Nernst equation.
where [C.sub.m] is membrane capacitance of a neuron, [V.sub.m] is membrane potential, [E.sub.Na] and [E.sub.K] are Nernst potentials of [Na.sup.+] and [K.sup.+], and [E.sub.l] is the potential while leakage current is zero.
TABLE 1: The conversion of Nernst equation [c.sub.in]/[c.sub.out] = exp([DELTA]V zF/RT) for bivalent ions as [Mg.sup.2+], [Mn.sup.2+], [Fe.sup.2+], and [Zn.sup.2+] shows strong relation between the actual membrane potential and ability of the cell/mitochondrium to attract and absorb the ions into the cell/mitochondrium.
(4) The anomalous Nernst effect is a thermoelectric effect discovered about 100 years ago, which relates to the magnetic property of a conductive material.

These measurements were carried out using a Bruker spectrometer (EQUINOX 55) equipped with a DT-GS detector in the range of 400-4000 [cm.sup.-1] with a Nernst rod as an excitation source.
The FC Nernst voltage is equal to 1.22 V with [H.sub.2]O generated [27].
