Solvations of isolated ion and embryo vacancy. (a) In case of ion (cation): Entropy is produced by the solvation energy emitted from the ionic cloud. \(+ Q_{ion}\), ionic charge of cation; \({\Delta }S\), produced entropy; \(T\), absolute temperature. (b) In case of positive ionic vacancy: Instead of entropy production, the vacancy core is expanded by the solvation energy, i.e., it is stored in the vacancy core. \(+ Q_{V}\), polarized charge of positive vacancy; \({\Delta }U\), solvation energy stored in vacancy core.
