Publication number: 20130142693Abstract: Embodiments of the present disclosure combine a suitable photocatalyst with a non-conducting matrix such as plastic, glass or rubber for the purpose of the production of activated electrons, needed in the creation of hydrogen peroxide, in the presence of light of a suitable frequency or frequencies and water. A suitable photocatalyst such as anatase titanium dioxide is combined with a plastic such as polypropylene as one would a pigment. The impregnated plastic can be immersed in water whereupon activated electrons and holes (electron absences in the valence band of the plastic substrate acting as a semiconductor) are produced on the surface of the photocatalyst upon irradiation. Activated electrons are an excellent oxidizer, disinfectant, purifier and go on to kill bacteria, algae, etc. in the water, as well as to reduce water hardness including mineral deposits. Unused hydrogen peroxide breaks down into hydrogen ion and free oxygen in a short time.Type: ApplicationFiled: November 26, 2012Publication date: June 6, 2013Applicant: EARTH TONE ENERGIES, LLCInventor: Earth Tone Energies, LLC

Publication number: 20130142694Abstract: The invention relates to a method and to a device for quickly decontaminating and sterilizing preferably thermolabile goods using a plasma gas that is preferably generated from air as a process gas, with the subsequent humidification of said plasma gas with water. The method comprises the following steps: generating a plasma from air as the process gas, which forms reactive nitrogen and oxygen species; oxidizing NO to form NO2 at temperatures below 400° C. so that a plasma-activated gas mixture forms having an NO2 content of at least 0.3%; bringing said plasma-activated gas mixture in contact with water in one or more of the states of aggregation thereof; bringing the latter gas mixture in contact with the objects to be decontaminated or sterilized.Type: ApplicationFiled: May 9, 2011Publication date: June 6, 2013Applicant: Leibniz-Institut fuer Plasmaforschung und Technologie e.
