title: Freezing-Facilitated Dehydration Allowing Deposition of ZnO from Aqueous Electrolyte.
abstract: When an aqueous NaCl solution with low concentrations of transition metal ions is frozen, most of the solutes are concentrated in the freeze concentrated solutions (FCS). However, Zn2+is often accumulated at sites where other elements are not detected. X-ray absorption near-edge structure spectroscopy at the Zn K-edge indicates the formation of ZnO. A possible mechanism for the ZnO formation is discussed.
