Abstract: A novel photocatalytic oxidation system that combines long lifetime, high-power light emitting diodes (LEDs) with efficient, visible light-activated photocatalysts for the destruction of Volatile Organic Compounds (VOCs) and other pathogens in air and water flow systems under ambient conditions of temperature and pressure is described. The technology uses the combination of visible photocatalysts with robust visible LEDs, uniform side emission fiber optics, and efficient catalyst surface illumination technologies to create a photocatalytic oxidation unit for air and water purification. This combined approach leads to numerous performance benefits including high VOC conversion efficiency, compact reactor volume, low pressure drop, and the elimination of conventional ultraviolet (UV) mercury lamp logistics and hazards.

Abstract: An optical oxygen laser has a source of oxygen. A cryoreactor has an input connected to the source of oxygen. An optical pump is coupled to the cryoreactor and excites the oxygen to form an singlet delta oxygen, an excited state of oxygen. An optical resonator cavity receives the excited state oxygen and has a laser output.

Abstract: A two phase reactor includes a source of liquid reactant and a source of gas reactant. A chamber has an inlet coupled to the source of gas reactant and a flat jet nozzle coupled to the source of the liquid reactant.

Abstract: A system for chemical and biological decontamination has a source of oxygen. A reactor is coupled to the source oxygen. An optical source is coupled to the reactor. The system produces singlet delta oxygen that neutralizes chemical and biological contaminants.
