ActiveUS20060008379A1Reduce or even removeMinimize residual amountGaseous substancesDeodrantsHotel roomVapor generator
A system for microbially and / or chemically decontaminating a room such as a hotel room includes a vapor generator which supplies a decontaminant vapor, such as hydrogen peroxide vapor to the room. The room is then aerated to a level at which it is safe for normal occupants to enter. By using a two step aeration, with a second step at lower humidity than the first, the concentration of residual hydrogen peroxide is reduced rapidly to safe levels of 1 ppm or less, typically about 0.5 ppm, in under four hours. The room is rendered substantially free of contaminants, such as those responsible for Severe Acute Respiratory Syndrome (SARS), Norwalk virus, and unpleasant odors.

Sterilization method and apparatus

A method of sterilizing an article by sequentially exposing the article to hydrogen peroxide and ozone is disclosed. The article is exposed under vacuum first to an evaporated aqueous solution of hydrogen peroxide and subsequently to an ozone containing gas. The exposure is carried out without reducing the water vapor content of the sterilization atmosphere, the water vapor content being derived from the aqueous solvent of the hydrogen peroxide solution and from the decomposition of the hydrogen peroxide into water and oxygen. The complete sterilization process is carried out while the chamber remains sealed and without removal of any component of the sterilization atmosphere. For this purpose, the chamber is initially evacuated to a first vacuum pressure sufficient to cause evaporation of the aqueous hydrogen peroxide at the temperature of the chamber atmosphere. The chamber is then sealed for the remainder of the sterilization process and during all sterilant injection cycles. Keeping the chamber sealed and maintaining the hydrogen peroxide and its decomposition products in the chamber for the subsequent ozone sterilization step results in a synergistic increase in the sterilization efficiency and allows for the use of much lower sterilant amounts and sterilization cycle times than would be expected from using hydrogen peroxide and ozone in combination.

Tungsten oxide/titanium dioxide photocatalyst for improving indoor air quality

A tungsten oxide / titanium dioxide photocatalyst coating oxidizes contaminants in the air that adsorb onto the coating into water, carbon dioxide, and other substances. The tungsten oxide forms a monolayer on the titanium dioxide. When photons of the ultraviolet light are absorbed by the tungsten oxide / titanium dioxide photocatalyst coating, an electron is promoted from the valence band to the conduction band, producing a hole in the valence band. The holes in the valence band react with water applied on the tungsten oxide / titanium dioxide photocatalyst coating, forming reactive hydroxyl radicals. When a contaminant in the air is adsorbed onto the tungsten oxide / titanium dioxide photocatalyst, the hydroxyl radical attacks the contaminant, abstracting a hydrogen atom from the contaminant. The hydroxyl radical oxidizes the contaminant, producing water, carbon dioxide, and other substances. The tungsten oxide / titanium dioxide photocatalytic coating has low sensitivity to humidity variations.
