Latest Patents

One of Toshima's latest patents is titled "Film of iron (III) hexacyanoferrate (II) and process of synthesizing same." This patent discloses a process 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 of an iron(III) ion-containing solution and a hexacyanoferrate(III) ion-containing solution, followed by electrolysis. This results in the deposition of iron(III) hexacyanoferrate(II) on the surface of the cathode.

Another significant patent is for "Electrochromic display devices using iron(III) hexacyanoferrate(II) salt." This invention comprises an electrolyte contained between a pair of spaced-apart substrates. A set of electrodes is disposed on at least one of the substrates in contact with the electrolyte, and a layer of electrochromic material is placed on at least one of the electrodes. The electrochromic material includes a color-reversible salt of iron(III) hexacyanoferrate(II), which exhibits different colors depending on its oxidation-reduction state. This technology allows for reversible electrochemical oxidation and reduction, resulting in a corresponding reversible color change exhibited by the display electrode.
