Abstract: An air purification reactor is described that has a variety of improvements. In one aspect, the air purification reactor includes an ionizer (or plasma chamber), an electrostatic filter, a photocatalyst, and a UV light source that is distinct from the ionizer. The ionizer is arranged to introduce ions into a gaseous fluid stream passing through the air purification device. The electrostatic filter is located downstream of the ionizer and is arranged to electrostatically filter particles from the fluid stream. The UV light source is positioned to subject the photocatalyst to ultraviolet light and may be arranged upstream, downstream, or intermediate the electrostatic filter. With this arrangement, the ultraviolet light that impinges on the photocatalyst causes a photocatalytic oxidative reaction to occur at the photocatalyst that is capable of reducing volatile organic compounds carried in the fluid stream. In other (separate) aspects, the reactor includes an absorber or an oxidation catalyst. Generally, the various aspects of the invention may be used separately or in combination with one another.

Abstract: This invention relates to an air purifier that uses both transportation vehicles battery and conventional indoor power supply, employs ultraviolet radioactive rays to kill bacteria, viruses and molds in the air and to increase the amount of anions. This air purifier works with any air conditioners or machines of all sizes, at exhaust inlet or outlet, as well as inside the surface shield or outside of air conditioning devices and dehumidifiers and electric fans of all sizes. This air purifier draws indoor air in and out of the air purifier, kills bacteria, viruses and moulds in the air and discharges electricity by means of negative high voltage output through carbon fibers to produce anions, so as to improve the quality of the air.

Abstract: A multi-function air treatment apparatus includes a photo-ionizing assembly and a negative ion generator. The photo-ionizing assembly emits a predetermined wavelength of light that produces ozone when it impinges upon air. When a portion of the light impinges on a target material, radicals and ions that bond with and reduce some of volatile organic compounds in the air are produced. The negative ion generator produces negative ions and a radiating negative electrostatic field from an outer high dielectric surface by an electrical charge applied to an enclosed conductive inner surface.

Abstract: A method is for selectively removing gaseous pollutants from the ambient air, and a device is for implementing the method. Undesirable emissions may be selectively and completely removed from the ambient air using relatively simple equipment and a small amount of energy. Pollutants contained in the air to be purified are ionized by the action of optical radiation, based on resonant and/or non-resonant single-photon excitation and/or multiple-photon excitation, so that the ionized pollutants are drawn off and removed from the air to be purified, using an electric field. A small portion of the energy necessary for the ionization may also be applied in the form of microwave energy or electric-field energy. The method and device may be used in air-conditioning or other air-circulation systems.

Abstract: Elemental mercury is removed from emissions of coal-fired utilities by the selective photoionization of mercury atoms using ultraviolet light, followed by electrostatic precipitation of the mercury ions. Mercury is first exposed to light of a wavelength which boosts the mercury to an excited state. Then mercury is ionized using light of a different wavelength. The ionized mercury atoms are exposed to supersaturated water vapor to produce charged droplets which are precipitated, such that the exhaust effluent is substantially devoid of mercury or the mercury level is substantially reduced.

Abstract: A housing for purifying an air flow moving through it provides a reception space for receiving the air flow. The air is treated with mechanical filtration of particles larger than approximately 2 micron, ionizing with energetic ions, exposure to ultraviolet light radiation, and electrostatic precipitation of particles in the air inflow.

Abstract: A method for cleaning objects (e.g., wafers, integrated circuits, photonic devices, opto-electronic devices, piezoelectronic devices, microelectromechanical systems (“MEMS”), sensors, actuators, solar cells, flat panel displays (e.g., LCD, AMLCD), biological and biomedical devices) of particles (e.g., particulate contamination) that attach themselves to surfaces of the objects. The method includes applying a high energy laser source on a surface of a substrate to release one or more particles from the surface of the substrate while maintaining the substrate in a vacuum environment; and applying an electrostatic source directed to the substrate to attract the released one or more particles from the substrate to remove the one or more particles from the surface of the substrate. The method also removes the substrate from the vacuum environment.
