  • Publication number: 20100207050
    Abstract: The formation of cracks is suppressed in a drying process for a water-containing wet gel without modifying the gel and without using a reagent. A water-containing wet gel is dried by removing water and then removing the remaining solvent. For example, a wet-gel container storing water-containing wet gel, containing a wet gel and a solvent, is heated. The solvent is vaporized into an upper space of the wet-gel container. The solvent-containing gas diffuses into a dehydrating agent container, and water is removed by a dehydrating agent. This state is maintained for one to two days to remove almost all amount of water from the solvent. Thereafter, the dehydrating agent container is detached and the wet gel, from which water has been removed, is heated to almost completely remove the solvent, and further heated at a higher temperature to completely remove the solvent to obtain a crack-free dry gel.

The organic metal complex comprises an organic compound and a metal-based compound wherein the metal is selected from copper, nickel, and combinations thereof.

    Abstract: A column 1 is formed which includes a first column 10 in which an upper layer 14 made of sulfuric acid silica gel and a lower layer 15 made of silver nitrate silica gel are stacked and packed and a second column 20 packed with an alumina layer 23 and connected detachably to the lower end part of the first column 10. An oily liquid containing polychlorinated biphenyls, such as an electric insulating oil, is added to the upper layer 14 and then kept for a predetermined time in a state heated to at least 35° C. An aliphatic hydrocarbon solvent such as n-hexane is supplied to the upper layer 14 having been cooled to ordinary temperature. As a result, polychlorinated biphenyls captured by the first column 10 are dissolved in the aliphatic hydrocarbon solvent and then flows to the second column 20. The polychlorinated biphenyls are captured by that part of the alumina layer 23 which is located near the inlet of the second column 20. The second column 20 is then detached from the first column 10.

  • Patent number: 7699913
    Abstract: An insert for sports gear and footwear has a compliant casing formed of fabric sheeting that incorporates regions of fused or otherwise integral regions of activated carbon. A desiccant such as silica gel in the form of spheroidal beads or other granules is loosely enclosed inside of the casing. The activated carbon has an affinity for odor-causing constituents such as organic compounds, and extracts airborne odor-causing constituents as air enters the casing. Inside the casing, the desiccant extracts airborne water vapor. The two-stage removal of odor-causing constituents and water vapor rapidly and effectively extracts moisture and odors. The silica gel and activated carbon are porous and have high surface areas available for adsorption, whereby the insert is adapted to maintain moisture and odors at low levels during long-term storage.

  • Publication number: 20100069236
    Abstract: Disclosed herein are a method of preparing Li-doped silica nanotubes using an anodic aluminum oxide (AAO) template, and a method of storing energy using the prepared Li-doped silica nanotubes. Unlike prior methods for preparing metal nanotubes, according to the disclosed preparation method, the Li-doped silica nanotubes having a uniform size can be easily obtained in mild conditions using a lithium precursor, a silica sol and an anodic aluminum oxide template. The preparation method comprises adsorbing the lithium precursor and the silica sol on the surface of the AAO template, drying the lithium precursor and the silica sol, adsorbed onto the AAO template, in a vacuum, to form nanotubes, and then drying the nanotubes. The Li-doped silica nanotubes prepared according to the disclosed method can be used as economical hydrogen storage materials, electrode materials for lithium secondary batteries, or energy storage sources for automobiles or other transportation means.

  • Patent number: 7662292
    Abstract: Media for selectively removing radium ions from water where manganese oxide (DMO) has been dispersed in a cation ion exchange resin (gel or macroporous) to adsorb radium ions. The media is manufactured by precipitating a soluble manganese (II) salt such as manganous sulfate with a permanganate salt such as sodium permanganate inside a strong acid cation (SAC) to form a resin containing highly dispersed manganese oxides. The resin is then post treated with a reducing agent such as sodium metabisulfite (Na2S2O2) to prevent the leaching of soluble manganese from the resin. The reducing treatment ensures that soluble manganese species will be converted into an insoluble oxide form.

  • Patent number: 7622422
    Abstract: A method of preparing an ionic conducting gel in solid form, known as ionogel. The method includes a step of mixing an ionic liquid with at least one molecular precursor containing at least one hydrolyzable group, if necessary in the presence of an acid, such as a carboxylic acid. The mixture is subsequently left to stand for one or more days until a gel is formed by polycondensation of the molecular precursor(s). The gel contains the aforementioned ionic liquid and can be set, in particular in transparent monolithic solid form.

  • Publication number: 20090209418
    Abstract: Silica gel is impregnated as an impregnating substance into pores of an activated carbon having mesopores and macropores. Since the mesopores and the macropores are impregnated with the silica gel, they are made narrow and small whereby a pore size ratio within a range of 1 to 10 nm is increased.
