  • Process of ultrasonic spray pyrolysis deposition of one or more electrochromic and/or electrolytic films on a substrate
    Patent number: 10254614
    Abstract: A process of making an electrochromic or an electrolytic film by Ultrasonic Spray Pyrolysis (USP) deposition on a substrate comprising: mixing a surfactant to an aqueous precursor solution comprising an electrochromic component or an electrolytic component to provide a spray solution; introducing the spray solution into an ultrasonic spray deposition nozzle at a constant flow rate between 0.1 mL/min and 2 mL/min and applying an ultrasonic frequency between 80 and 120 kHz to generate atomized droplets of the precursor solution; entraining the atomized droplets with a controlled jet of air as gas carrier at a pressure between 0.50 to 2.0 psi, onto a pre-heated substrate at a temperature of 200 to 450° C.; thermally converting the atomized droplets when depositing onto the pre-heated substrate to generate an electrochromic or an electrolytic film.

  • Method for the production of functionalised short carbon nanotubes and functionalised short carbon nanotubes obtainable by said method
    Patent number: 7419650
    Abstract: The present invention is related to a method for producing functionalised short carbon nanotubes with at least one open tip by mechanical treatment of long carbon nanotubes, wherein said long nanotubes are submitted to mechanical milling forces in the presence of a reactant able to chemically react with the nanotubes so that short carbon nanotubes comprising at least one specific chemical group are obtained.
