Latest Patents
One of Shibayama's latest patents is titled "Film of iron (III) hexacyanoferrate (II) and process of synthesizing same." This patent discloses a method for synthesizing iron(III) hexacyanoferrate(II) as a blue insoluble product on the surface of a working electrode. The process involves immersing a pair of electrodes in a solution mixture containing iron(III) ions and hexacyanoferrate(III) ions, followed by electrolysis. This results in the deposition of iron(III) hexacyanoferrate(II) on the cathode's surface.
Another significant patent is for "Electrochromic display devices using iron(III) hexacyanoferrate(II) salt." This invention describes an electrochromic display device that includes an electrolyte between two substrates. A set of electrodes is placed on at least one substrate, in contact with the electrolyte. The electrochromic material, which comprises a color-reversible salt of iron(III) hexacyanoferrate(II), allows for a reversible color change depending on its oxidation-reduction state.
