  • Publication number: 20070172384
    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.

  • Publication number: 20070154854
    Abstract: A system for using cool hydrogen flame for destruction of VOCs and odorous compounds comprises an existing exhaust system for an industrial process or a factory. The existing exhaust system comprises at least an exhaust duct or a chimney for exhaust gases. The exhaust gases may comprise of odorous compounds such as DMS, MDSO and other VOCs. The system further comprises at least one burner nozzle for generating a configurable hydrogen surface-mixed diffusion flame. The main by-product from this hydrogen flame is water and free radicals. These free radicals produced during hydrogen combustion are extremely reactive and highly oxidative in nature especially hydroxyl radicals. As such, odorous compounds such as VOCs, DMS and DMSO would easily be destroyed by these free radicals produced during hydrogen combustion.

  • Publication number: 20060163154
    Abstract: A method for processing environmental samples to remove or otherwise reduce the level of certain chemical species. In a preferred embodiment, the present invention contemplates a process for reducing the level of inorganic and/or organic chemical species in wastewater or other aqueous or semi-aqueous environments or other waste environments. The present invention further provides compositions of bacteria useful in modulating the redox potential of an environment to generate redox mediator species which facilitate the removal of particular inorganic or organic molecules from the environment samples. The redox potential is preferably modulated through microbial-mediated oxidation or reduction of metal cations under aerobic or anaerobic conditions, respectively. The present invention is further directed to a computer program which facilitates the controlled modulation of the redox potential of an aqueous or semi-aqueous environment or other environments.
