Ion–solvent interaction of the tetraalkylammonium ions (R4N+) in N-methylacetamide has been studied from the point of view of electrical conductance and the derived Walden product. The results indicate R4N+ ions to be structure breakers in this solvent, quite opposite to their general behavior in aqueous solutions. The effect is conspicuous in the smaller Me4N+ and Et4N+ ions, but is less marked in the larger ions.

The carbon fiber/metal oxide/metal oxynitride layer sandwich structure is constructed in the electrode to form a mini-plate capacitor. High dielectric constant metal oxides act as dielectric to increase their capacitance.
