Purified Hydrogen Peroxide Gas Microbial Control Methods and Devices
The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.
COMPOSITIONS AND METHODS FOR HYDROCARBON FUNCTIONALIZATION
Embodiments of the present disclosure provide for methods of hydrocarbon functionalization, methods and systems for converting a hydrocarbon into a compound including at least one group ((e.g., hydroxyl group) (e.g., methane to methanol)), functionalized hydrocarbons, and the like. Systems and methods as described herein can utilize photocatalysis.
LIGHT IRRADIATION DEVICE AND PRINTER
The disclosure relates to a light irradiation device which can improve curability of photo-curable materials. A light irradiation device includes a first supply section having a porous portion, the first supply section being capable of supplying a gas to a photo-curable material through the porous portion; and an irradiation section disposed in alignment with the porous portion or disposed downstream from the porous portion, the irradiation section being capable of irradiating the photo-curable material with light.
Method to produce a calibration, reagent or therapeutic gas by exposing a precursor gas to ultraviolet light
The present invention provides a means of producing nitric oxide (NO) by photolysis of nitrous oxide (N.sub.2O) 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 NO.sub.2 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. The method may also be applied to the production of controlled concentrations of other gases as well such as CO and F.sub.2 by using reagent gases other than N.sub.2O.
Ultraviolet reactor with planar light source
Various ultraviolet (UV) reactors and their methods of fabrication are disclosed. One exemplary process comprises forming a set of parallel channels in a slab of ultraviolet transparent material. The process also comprises providing a reactor substrate with an input manifold and an output manifold. The process also comprises joining the slab of ultraviolet transparent material and the reactor substrate. The input manifold, output manifold, and set of parallel channels are in fluid communication after the joining step. The process also comprises providing a planar ultraviolet light source isolated from the set of parallel channels by the shaped slab of ultraviolet-transparent material. The set of parallel channels and a defining plane of the planar ultraviolet light source are parallel in the assembled ultraviolet reactor.
BARRIERS FOR GLASS AND OTHER MATERIALS
Embodiments described herein generally relate to articles and methods for containing compositions comprising hydrogen gas. In some embodiments, the article comprises a container that comprises glass. In some cases, the container may further comprise TiO.sub.2, which may be embedded within the glass, coated on the glass, etc. The container further may contain a composition within the container. In some cases, the composition may comprise dissolved hydrogen gas. Such compositions may be useful, for example, for the treatment of animal and human diseases, for improvement in athletic performance, for the enhancement of the overall health of a subject, or the like.
COMPOSITIONS AND METHODS FOR ENTRAPPING PROTEIN ON A SURFACE
The present invention provides a formulation to link protein to a solid support that comprises one or more proteins, Oligo-dT and one or more non-volatile, water-soluble protein solvents, solutes or combination thereof in an aqueous solution. Further provided is a method of attaching a protein to a surface of a substrate. The formulations provided herein are contacted onto the substrate surface, printed thereon and air dried. The substrate surface is irradiated with UV light to induce thymidine photochemical crosslinking via the thymidine moieties of the Oligo-dT.
CURING METHOD AND CURING SYSTEM
To cure, with light irradiation, photocurable resin or electron beam-curable resin not containing a photopolymerization initiator.
Under an atmosphere equal to or lower than predetermined oxygen concentration for not causing oxygen inhibition to polymerization of photocurable resin or electron beam-curable resin, an ultraviolet ray in wavelength region corresponding to a light absorption characteristic of the photocurable resin or the electron beam-curable resin is irradiated on the photocurable resin or the electron beam-curable resin to polymerize the photocurable resin or the electron beam-curable resin. After an ultraviolet ray is irradiated on the photocurable resin or the electron beam-curable resin to polymerize at least a surface layer, an electron beam is irradiated on the photocurable resin or the electron beam-curable resin to polymerize a deep part, and the entire photocurable resin or the entire electron beam-curable resin is cured.
ADVANCED OXIDATION PROCESS FOR THE EXFOLIATION OF TWO DIMENSIONAL MATERIALS
A system for extracting two dimensional materials from a bulk material by functionalization of the bulk material in a reactor.
Transportable liquid produced from natural gas
A system and a method for converting Natural Gas (NG) to high energy transportable liquid (such as gasoline) are disclosed. A semiconductor UV-source is used for initiate a photo lytic reaction between methane molecules and photons having energy equal or bigger than the energy of dissociation of the CH bond in methane. The formed radicals are further react to produce higher molecular weight hydrocarbons, while hydrogen gas is separates from the reaction mixture in order to avoid reverse reactions.
