  • Apparatus and method for cleaning glass substrates using a cool hydrogen flame
    Patent number: 7790477
    Abstract: Contaminants from surfaces of temperature sensitive substrates, such as glass substrates are removed by exposing the surfaces to a hydrogen Surface-mixed diffusion flame for a predetermined duration of time. The predetermined duration of time being insufficient to heat up the surfaces substantially thereby causing damage to the temperature sensitive substrates.
    Type: Grant
    Filed: February 6, 2009
    Date of Patent: September 7, 2010
    Assignee: Agency For Science, Technology And Research
    Inventors: David Tee Liang, Tuti Mariana Lim, Sau Ngen Chen
  • Methods for sterilizing medical devices using a hydrogen surface-mixed diffusion flame
    Patent number: 7575715
    Abstract: A method for sterilizing medical devices, comprising the steps: producing a plurality of hydrogen surface-mixed diffusion flame; exposing the plurality of hydrogen surface-mixed diffusion flame to the medical devices for a predetermined period of time; and exposing the medical devices to the plurality of hydrogen surface-mixed diffusion flame at a predetermined distance; wherein the hydrogen surface mixed diffusion flame further produces free radicals for further sterilizing of the medical devices.
