  • Patent number: 7211607
    Abstract: Nanostructured chromium(III)-oxide-based materials using sol-gel processing and a synthetic route for producing such materials are disclosed herein. Monolithic aerogels and xerogels having surface areas between 150 m2/g and 520 m2/g have been produced. The synthetic method employs the use of stable and inexpensive hydrated-chromium(III) inorganic salts and common solvents such as water, ethanol, methanol, 1-propanol, t-butanol, 2-ethoxy ethanol, and ethylene glycol, DMSO, and dimethyl formamide. The synthesis involves the dissolution of the metal salt in a solvent followed by an addition of a proton scavenger, such as an epoxide, which induces gel formation in a timely manner. Both critical point (supercritical extraction) and atmospheric (low temperature evaporation) drying may be employed to produce monolithic aerogels and xerogels, respectively.

  • Publication number: 20070003435
    Abstract: An inspection tester that can be used anywhere as a primary screening tool by non-technical personnel to determine whether a surface contains explosives. It includes a body with a sample pad. First and second explosives detecting reagent holders and dispensers are operatively connected to the body and the sample pad. The first and second explosives detecting reagent holders and dispensers are positioned to deliver the explosives detecting reagents to the sample pad. A is heater operatively connected to the sample pad.

  • Patent number: 7087544
    Abstract: Disclosed herein is a method to produce ceramic materials utilizing the sol-gel process. The methods enable the preparation of intimate homogeneous dispersions of materials while offering the ability to control the size of one component within another. The method also enables the preparation of materials that will densify at reduced temperature.

  • Publication number: 20060042417
    Abstract: New sol-gel methods can be employed to generate high surface area porous iron (III) oxide-based solids. Chemical reduction of such porous solids at low temperatures allows the preparation of high surface area porous iron with little sintering, with the only byproduct being water. The material is readily pyrophoric and has utility in new decoy flares. The material, prepared by this synthetic route, eliminates the use of hot caustic leaching solutions. It does not require the incorporation of any hazardous materials or processes that are not already used in current production methods.

  • Publication number: 20050138006
    Abstract: A method for implementing a hardware database management system in hardware is described. A parser takes standardized database statements and converts those statements into a set of executable instructions and associated data objects. The executable instructions and data objects are then sent to the execution tree engine where an execution tree is created, the execution tree forming the order of execution for the executable instructions. The graph engine receives those executable instructions from the execution tree engine that require access to the database in memory and manipulates the information in the database as required by the executable instructions for implementing the standardized database statement.

  • Publication number: 20050092405
    Abstract: Sol-gel chemistry is used for the preparation of energetic materials (explosives, propellants and pyrotechnics) with improved homogeneity, and/or which can be cast to near-net shape, and/or made into precision molding powders. The sol-gel method is a synthetic chemical process where reactive monomers are mixed into a solution, polymerization occurs leading to a highly cross-linked three dimensional solid network resulting in a gel. The energetic materials can be incorporated during the formation of the solution or during the gel stage of the process. The composition, pore, and primary particle sizes, gel time, surface areas, and density may be tailored and controlled by the solution chemistry. The gel is then dried using supercritical extraction to produce a highly porous low density aerogel or by controlled slow evaporation to produce a xerogel. Applying stress during the extraction phase can result in high density materials.

  • Publication number: 20040158572
    Abstract: A database and database management system are implemented entirely in hardware. The information forming the database is stored in random access memory which is connected to a data flow engine. The data flow engine is able to process statements in standard database protocols such as SQL and XML, and to manipulate (read, write and alter) the database in accordance with the statements. The data flow engine is connected to a microprocessor that receives the statements from the database user or database application server and sends them to the data flow engine for processing. The results from the data flow engine are returned to the microprocessor and the microprocessor then returns the results to the user or application server.
