  • Patent number: 8916225
    Abstract: The present invention provides a method for coating an inner surface of a polyvinyl chloride medical tube containing a plasticizer with an antithrombogenic material composed of a specific (meth)acrylate copolymer. The simple method of the present invention is capable of evenly and efficiently coating an inner surface of a polyvinyl chloride medical tube with a sufficient amount of an antithrombogenic material without causing appearance deterioration or uneven coating due to elution of the plasticizer. The method is performed by passing through a tube a solution that is prepared by dissolving an antithrombogenic material in a solvent composed of water and at least one alcohol that is adjusted to dissolve the copolymer of the antithrombogenic material but does not dissolve the plasticizer, then subsequently passing water through the tube, and finally drying the tube.

    Abstract: Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution.

    Abstract: Germania-based sol-gel organic-inorganic hybrid coatings were prepared for on-line coupling of capillary microextraction with high-performance liquid chromatography. A germania-based sol-gel precursor, tetra-n-butoxygermane and a hydroxy-terminated triblock copolymer, poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide), were chemically anchored to the inner walls of a fused silica capillary (0.25 mm I.D.). Scanning electron microscopy images of the sol-gel germania triblock polymer coating were obtained to estimate the coating thickness. The analyte distribution constants between a sol-gel germania organic-inorganic hybrid coating and the samples (Kcs) were determined. For a variety of analytes from different chemical classes, including polycyclic aromatic hydrocarbons (PAHs), ketones, alcohols, phenols, and amines, the Kcs values ranged from 1.8×101 to 2.0×104. The sol-gel germania triblock polymer coatings survived exposure to high temperature solvent conditions (200° C.

  • Patent number: 8206783
    Abstract: Methods and process steps for cleaning and providing barrier coatings to interior walls of piping systems. An entire piping system can be cleaned in one single pass by dry particulates forced by air and the piping system coated in one single pass. Pipes can be protected from water corrosion, erosion and electrolysis. Pipes having diameters of approximately ?? up to approximately 6? are treatable. Piping systems such as potable water lines, natural gas lines, HVAC, drains, and fire sprinkler systems in homes. apartments, high-rise hotel/resorts. office towers, high-rise apartment and condominiums and schools, can be treated. The coating forms an approximately 4 mils or greater covering inside the pipes. Buildings can return to service within approximately 24 to approximately 96 hours.

  • Publication number: 20120128551
    Abstract: Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution.

  • Publication number: 20120118805
    Abstract: Methods for depositing a stationary phase in a tube for chromatography, in particular, as a variable gradient column are disclosed. The methods include providing a tube, loading the tube with a concentration gradient of a stationary phase precursor along its length, and removing the solvent such that the stationary phase precursor is deposited within the tube as a stationary phase to form a chromatography column. The concentration gradient is formed by combining at least a first fluid and a second fluid, with the first fluid containing the stationary phase precursor in a solvent.

  • Patent number: 8173224
    Abstract: The invention relates to a process for impregnating wood or wood based material. A working solution is preheated to a temperature above the atmospheric boiling point (“a super hot temperature”) above the atmospheric boiling point (“a super hot temperature”) of the working solution, at an elevated pressure sufficient to maintain the working solution in the liquid phase. The working solution is contacted with a wood or wood based material at a super hot temperature and an elevated pressure to cause impregnation of the solution into the wood or wood based material. The impregnated wood or wood based material and any remaining working solution, waste material and/or by-products are then separated.

  • Publication number: 20120070574
    Abstract: Disclosed is a pretreatment method for improving antioxidation of steel T91/P91 in high temperature water vapor, which includes applying a slurry, containing rare earth oxide, on a surface of a substrate; holding the temperature in a gas mixture environment of inert gas and water vapor after drying; and cleaning away the solid powder left by the slurry on the surface, thereby obtaining the substrate with a surface rich in chromium and having a small amount of rare earth oxide. As a result of the method, the antioxidation capability of steel T91/P91 in the 500-750° C. water vapor environment can be improved, and films rich in chromium oxide can be formed on the surface of steel T91/P91.

  • Patent number: 8124166
    Abstract: The present invention relates generally to medical devices with therapy eluting components and methods for making same. More specifically, the invention relates to implantable medical devices having at least one porous layer, and methods for making such devices, and loading such devices with therapeutic agents. A mixture or alloy is placed on the surface of a medical device, then one component of the mixture or alloy is generally removed without generally removing the other components of the mixture or alloy. In some embodiments, a porous layer is adapted for bonding non-metallic coating, including drug eluting polymeric coatings. A porous layer may have a random pore structure or an oriented or directional grain porous structure. One embodiment of the invention relates to medical devices, including vascular stents, having at least one porous layer adapted to resist stenosis or cellular proliferation without requiring elution of therapeutic agents.

  • Patent number: 8105513
    Abstract: The present invention relates to a pipette tip which is fitted with a porous organic monolith which is doped with active particles. Due to a unique polymerization method, the extraction tips stay highly permeable which allows sample to pass through the monolithic bed. The extraction tip represents an ideal tool for solid phase extraction, especially for desalting, isolating and purifying biomolecules such as peptides and proteins.
