One light source activates the catalytic function of a semiconductor material in the fluid to reduce the concentration of contaminants in the fluid, such as by breaking down organic contaminants into non-toxic compounds. A second light source acts directly on living biological entities to sterilize or kill them and thereby disinfect the fluid, and can also serve to activate a semiconductor photocatalyst that in turn causes further damage to biological contaminants. The semiconductor photocatalyst is desirably attached to an optically transmitting fiber substrate in the fluid. The second light source in one embodiment is external to the fluid and illuminates the photocatalyst through transmitting surfaces in a fluid containment vessel. The light sources can comprise respective sets of plural LEDs.

  • Publication number: 20100266083
    Abstract: A capsule for holding, irradiating, and eluting a material is provided. Methods of fabricating and using the capsule are also provided. The capsule may include a multidiameter tube with a first end region, a second end region, and a middle region. Washers and filters are provided in the end regions and the end regions may be sealed using various methods and materials with the end caps press fit into the end regions. The middle region is designed to store a material to be irradiated by a neutron flux source. The capsule components may be made from materials having a low nuclear cross section so that the capsule may be handled safely after an irradiation step is performed. The capsule is also designed to have a symmetric configuration as an elution and irradiation column so that the same capsule may be used to elute the material within the middle region of the capsule after an irradiation step is performed.

  • Publication number: 20100224480
    Abstract: The invention relates to a method for photocatalytic separation of a dispersed substance from a surfactant-containing dispersion. The surfactant-containing dispersion contains at least one dispersant, one dispersed substance, one surfactant and one photocatalyst. Irradiation of the photocalyst causes the decomposition or modification of the surfactant allowing for the separation of the dispersed substance from the dispersant.

  • Publication number: 20100195185
    Abstract: Method for preparing a purified crystal for use in an optical component, from an impure crystal having impurities or crystal defects capable of causing a specific absorption of incident light, includes heating the impure crystal to a temperature at which ions in the crystal are mobile and provide conductivity. A part of the crystal is illuminated with an electromagnetic purifying beam having a frequency in or near a visible frequency range so as to optically excite and migrate charges in the crystal, the charges being compensated by a counter-migration of the ions so as to be fixed in place thereafter so as to provide a purified crystal zone. The crystal is cooled to a future operating temperature.

    Abstract: A gas conversion system for removing carbon dioxide from gases includes a duct through which gases are circulated. The duct has a port for introducing a reaction agent into the duct to the gases. An electron beam emitter is positioned relative to the duct for directing an electron beam into the duct to cause components of the carbon dioxide and the reaction agent to react to remove carbon dioxide from the gases and release oxygen.

  • Patent number: 7727681
    Abstract: Transmissivity is restored to a gallium stained substrate by directing an electron beam to the substrate in the presence of an etching gas. For higher concentrations of implanted gallium, the transparency can be substantially restored without reducing the thickness of the substrate. For lower doses of implanted gallium, the transmission is restored to 100%, although the thickness of the substrate is reduced. The invention is suitable for use in the repair of photolithography masks.

  • Publication number: 20100072671
    Abstract: A nano-imprint lithography template includes a rigid support layer, a cap layer, and a flexible cushion layer positioned between the support layer and the cap layer. Treating an imprint lithography template includes heating the template to desorb gases from the template. Heating the template includes radiating the template at a selected wavelength with, for example, infrared radiation. The selected wavelength may correspond to a wavelength at which the template material is strongly absorbing.

  • Publication number: 20100067087
    Abstract: Method for treating a nominally pure crystal having non-linear optical properties. The nominally pure crystal contain foreign atoms at a residual concentration of less than 20 ppm so as to provide specific absorption of incident light. The method includes determining, based on testing on a specifically doped reference crystal of same type as the nominally pure crystal, a threshold value. The threshold value is defined by a temperature at which a migration of ions in the nominally pure crystal to the surface of the nominally pure crystal ceases. The foreign atoms are transformed to a higher valance state by a thermally-supported oxidation process including heating the nominally pure crystal at a heating rate that increases by less than 3° C. per minute to a maximum temperature above the threshold value and below a Curie temperature of the nominally pure crystal. An electrical voltage is applied so as to eliminate electrons released during the oxidation process from the nominally pure crystal.

The reactor according to the present invention is preferably a compounded parabolic concentrator or a compounded ellipsoidal concentrator. The electromagnetic energy delivered and concentrated into and inside the reactor can be of any range of the electromagnetic spectrum, such as ultra-violet, visible, infra-red, microwave etc., or combination thereof. The acoustic energy is of any suitable frequency.
