  • Patent number: 10207927
    Abstract: The present invention provides a means of producing nitric oxide (NO) by photolysis of nitrous oxide (N2O) at ultraviolet wavelengths. One application is the production of a known concentration of NO in a diluent gas for calibration of analytical instruments that measure nitric oxide in gases such as exhaled breath, ambient air and automobile exhaust. A potentially important medical application is the production of NO for inhalation therapy, an advantage being that very little toxic NO2 gas is produced. The method is useful for producing NO for industrial applications as well. Advantages of this method of NO production include the use of a single, inexpensive, readily available reagent gas of very low toxicity. Furthermore, the concentration of NO produced can be easily controlled by varying the ultraviolet (UV) lamp intensity and relative gas flow rates.

  • Patent number: 10077921
    Abstract: The present invention relates to an improved solar energy concentrating system. The system comprises a dual axis sun tracking paraboloid dish collector on a polar mount, with a re-reflecting mirror in top of the paraboloid dish, which reflects the concentrated solar irradiation into an opening in the paraboloid dish into a light pipe and with a movable third mirror redirects the light into a second light pipe along the polar axis, which with a fourth fixed mirror, sends the concentrated solar irradiation into a third light pipe to the cavity receiver. The invention replaces the need of flexible connectors to accommodate the movement of the mirror, with a combination of mirrors and light pipes, transferring the solar irradiation to a cavity-receiver. Dual axis tracking systems can capture more solar energy, on a more constant basis throughout the day and the year, and by reflecting directly into the cavity-receiver, thermal losses are minimized.

  • Patent number: 8721899
    Abstract: Provided are methods and systems for continuously producing low concentrations of chlorine dioxide from dilute solutions of sodium chlorite. The low concentrations of chlorine dioxide produced allow for reduced exposure risk with direct application of the chlorine dioxide stream. The incorporation of a suitable chlorine dioxide detector permits continuous monitoring and control of chlorine dioxide production ensuring that the process stays within regulatory guidelines. Pretreatment of reaction water is preferred for achieving suitable conversion rates of the low concentrations of chlorite to chlorine dioxide.

  • Patent number: 8663516
    Abstract: A process for manufacturing a block of material that imitates natural stone. The manufactured stone not only looks and appears like natural stone, but is also consistent with the composition of natural stone. The process comprises forming an aqueous mixture of limestone aggregates, treating the mixture with carbon dioxide under pressure and then highly compressing the treated mixture in a sealed mold. This process recreates the endogenous matrix of the natural stone and its original composition. The block of material is intended for construction and decoration purposes.

  • Publication number: 20130240348
    Abstract: Amongst the candidates for very high efficiency electronics, solid state light sources, photovoltaics, and photoelectrochemical devices, and photobiological devices are those based upon metal-nitride nanowires. Enhanced nanowire performance typically require heterostructures, quantum dots, etc which requirement that these structures are grown with relatively few defects and in a controllable reproducible manner. Additionally flexibility according to the device design requires that the nanowire at the substrate may be either InN or GaN. Methods of growing relatively defect free nanowires and associated structures for group IIIA-nitrides are presented without the requirement for foreign metal catalysts, overcoming the non-uniform growth of prior art techniques and allowing self-organizing quantum dot, quantum well and quantum dot-in-a-dot structures to be formed.

  • Publication number: 20130199922
    Abstract: This invention relates to novel methods for affecting, controlling and/or directing various reactions and/or reaction pathways or systems by exposing one or more components in a holoreaction system to at least one spectral energy pattern. In a first aspect of the invention, at least one spectral energy pattern can be applied to a reaction system. In a second aspect of the invention, at least one spectral energy conditioning pattern can be applied to a conditioning reaction system. The spectral energy conditioning pattern can, for example, be applied at a separate location from the reaction vessel (e.g., in a conditioning reaction vessel) or can be applied in (or to) the reaction vessel, but prior to other reaction system participants being introduced into the reaction vessel. The techniques of the present invention are applicable to inorganic reactions, organic reactions, biologic reactions and/or phase or structure change reactions.

    Abstract: A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes patterning a topography that includes an array of raised regions separated by a recessed portion. The array can be patterned by micro-printing using a stamp that has raised islands. The raised regions can have a height of 1 to 5 nm as measured from the recessed region. A magnetic alloy and a non-magnetic segregant are then co-sputtered. The magnetic alloy preferentially grows over the raised portions and the non-magnetic segregant grow preferentially over the recessed region between the raised portions.
