Method and apparatus for processing wafer surfaces using thin, high velocity fluid layer

Among the many embodiment, in one embodiment, a method for processing a substrate is disclosed which includes generating a fluid layer on a surface of the substrate, the fluid layer defining a fluid meniscus. The generating includes moving a head in proximity to the surface, applying a fluid from the head to the surface while the head is in proximity to the surface of the substrate to define the fluid layer, and removing the fluid from the surface through the proximity head by a vacuum. The fluid travels along the fluid layer between the head and the substrate at a velocity that increases as the head is in closer proximity to the surface.

Method and apparatus for ozone sterilization

The present invention provides a method and apparatus for sterilizing articles using an ozone-containing gas, where condensation of water from the sterilization atmosphere during the sterilization process is substantially prevented. The inventive sterilization method includes providing a sterilization chamber and placing an article into the sterilization chamber. The sterilization chamber is sealed prior to equalizing the temperature of the article and the atmosphere in the sterilization chamber. A vacuum is applied to achieve a preselected vacuum pressure in the sterilization chamber. Once the vacuum pressure is set, water vapour is supplied to the sterilization chamber. Ozone-containing gas is then supplied to the sterilization chamber and the sterilization chamber remains sealed for a preselected treatment period, where the sterilization chamber remains sealed throughout the whole process. Finally, vacuum in the sterilization chamber is released.

DNA base sequencing system

The present invention provides a DNA base sequencing system having a compact, simple and convenient structure.In one embodiment of the present invention, a reaction chamber module for pyrosequencing in which a multiple number of reaction vessels (reaction chambers) 10 and reagent-introducing narrow tubes 6 are integrated is formed in a device board 5. Reagents held in reagent reservoirs 1, 2, 3 and 4 mounted separately from this reaction chamber module are introduced into the reaction vessels 10 via reagent-introducing narrow tubes (capillaries) 6. The reagent-introducing narrow tubes (capillaries) 6 at the area of 2 cm from the reaction vessels 10 are structured with narrow capillaries having an inner diameter of about 0.1 mm and the conductance of these capillaries for the reagent solution determines the injection speed of the solution.Using the present invention, many kinds of DNAs can be analyzed simultaneously.

Water desalination process and apparatus

A process and system for purifying water is disclosed. For example, in one embodiment, the process may be used to remove a divalent salt, such as calcium sulfate, from a water source in order to prevent the divalent salt from precipitating during the process. The water source, for instance, may be fed to an ion separating device, such as an electrodialysis device. In the electrodialysis device, an ion exchange takes place between the divalent salt and another salt, such as a monovalent salt to produce two concentrated salt streams that contain salts having greater solubility in water than the divalent salt. In one embodiment, the two salt streams that are produced may then be combined to precipitate the divalent salt in a controlled manner. During the process, various other components contained within the water feed stream may also be removed from the stream and converted into useful products. In one particular embodiment, the process is configured to receive a byproduct stream from a reverse osmosis process.

Conversion of petroleum residua to methane

This invention discloses improvements on previous inventions for catalytic conversion of coal and steam to methane. The disclosed improvements permit conversion of petroleum residua or heavy crude petroleum to methane and carbon dioxide such that nearly all of the heating value of the converted hydrocarbons is recovered as heating value of the product methane. The liquid feed is distributed over a fluidized solid particulate catalyst containing alkali metal and carbon as petroleum coke at elevated temperature and pressure from the lower stage and transported to the upper stage of a two-stage reactor. Particulate solids containing carbon and alkali metal are circulated between the two stages. Superheated steam and recycled hydrogen and carbon monoxide are fed to the lower stage, fluidizing the particulate solids and gasifying some of the carbon. The gas phase from the lower stage passes through the upper stage, completing the reaction of the gas phase.

Method and apparatus for sustainable energy and materials

A process for the production of hydrogen from anaerobically decomposed organic materials by applying an electric potential to the anaerobically decomposed organic materials, including landfill materials and sewage, to form hydrogen, and for decreasing the time required to treat these anaerobically decomposed organic materials. The organic materials decompose to volatile acids such as acetic acid, which may be hydrolyzed by electric current to form hydrogen. The process may be continuously run in sewage digestion tanks with the continuous feed of sewage, at landfill sites, or at any site having a supply of anaerobically decomposed or decomposable organic materials.

The present invention provides a treatment apparatus. The apparatus contains a reservoir or generator for a treatment solution, a mechanism for delivering the treatment solution to a wound site, and a mechanism for applying the solution to a wound, tissue, bone or surgical cavity for treatment. The apparatus may apply the solution (e.g., a solution containing hypohalous acid) with, for example, an occlusive wound dressing, pulsative lavage device, hydrotherapy, hydrosurgical device, and / or ultrasound. A waste container may be operably connected to the apparatus for collecting waste from the wound by run-off, or by applying negative pressure (e.g. a vacuum). Because the apparatus of the invention can optionally be portable or mobile, the invention is suitable for use in hospitals and nursing homes, as well as for home wound care. The invention also provides a method for treating a wound (or other area needing treatment), and / or for reducing wound bioburden, by supplying a hypochlorous acid solution to the site, such as a wound colonized or infected with drug resistant bacteria, before, during, or after negative pressure wound therapy.
