  • Patent number: 11766641
    Abstract: A nanoadsorbent based filter is used for purification of fluoride and arsenic contaminated water. 140-150 g low cost (˜10 USD/kg) nanoparticles of gamma alumina of 20-25 mg/g fluoride and 25-30 mg/g arsenic adsorption capacity is incorporated in propylene filter without susceptibility of leaching incorporated nanoparticles in water. The cost of domestic defluoridation device containing low cost nanoalumina incorporated filters/cartridges along with housing, overhead tank, tubing and treated water storage container etc. is of very low cost of around 25 USD/device. The fluoride treatment cost would be <0.5 USD/100 lit for 4-5 mg/l fluoride water after 2-3 regenerations while, the arsenic treatment cost using domestic filtration device would be <0.25 USD/100 lit for 90-100 ?g/l arsenic (III) water.

  • Patent number: 10788210
    Abstract: A single-walled combustor includes a multi-layered wall having a first face defining a cooling plenum and an opposite second face. A thermal barrier coating of the wall may be secured to the second face and defines at least in-part a combustion chamber. A plurality of cooling circuits each extend through the base layer and the thermal barrier coating for flowing cooling air from the plenum and into the combustion chamber. Each circuit includes a first surface recessed from the second face and spaced from the thermal barrier coating with a channel defined in-part by the first surface and covered by the thermal barrier coating. A hole in the thermal barrier coating is in fluid communication between the channel and the combustion chamber. A method of manufacturing the circuit includes fabricating the base layer with the aperture and hole; then placing an insert into the channel prior to application of the coating over the base layer and insert.

  • Patent number: 9523166
    Abstract: Methods and kits for treating a fibrous substrate prior to forming an image thereon are provided. The method can include positioning a treatment sheet adjacent to the fibrous substrate, transferring a salt (e.g., calcium chloride, magnesium chloride, or a mixture thereof) from the treatment sheet to the fibrous substrate using a wetting solution (e.g., an aqueous solution, such as water) to carry the salt from the treatment sheet into the fibrous substrate, and drying the fibrous substrate such that the salt remains in the substrate. For example, the transfer of the salt from the treatment sheet into the fibrous substrate can be accomplished via pressing the backside of the treatment sheet such that the wetting solution flows from the treatment sheet into the fibrous substrate while carrying the salt.

The electrode having a porous active coating layer according to the present invention may be useful to enhance peeling and scratch resistances of the porous active layer and improve a lamination characteristic toward the porous active layer by introducing a porous active layer onto a porous substrate having pores, the porous active layer having heterogeneity of morphology toward a thickness direction in which a content ratio of the binder polymer/inorganic particles present in a surface layer is higher than that of the binder polymer/inorganic particles present inside the surface layer. Accordingly, the stability and performances of the battery can be improved at the same time since the detachment of the inorganic particles from the porous active layer may be reduced during the assembly process of the electrochemical device.

  • Patent number: 8323742
    Abstract: A process for foaming ceramic foams, in which the ceramic foams are produced from a precursor or a mixture of precursors which contain at least one ceramic-forming element and liberates at least one volatile reaction product during an inorganic gelation process. In one embodiment, foaming is based on a precursor containing crystals of the AlCl3(Pri2O) complex. The decomposition of the initial precursor produces polymerizing species dissolved in liquid isopropyl chloride. The solvent and growing AlOxCly(OPri)z species are mixed homogeneously so that the boiling point of the solution is raised above the boiling point of the pure isopropyl chloride. Polymerization takes place in the liquid until a critical polymer size is attained, whereupon a phase separation into polymer rich and solvent rich regions occurs. Since the expelled solvent is suddenly above its boiling point, bubbles start forming instantly.

The surfaces produced in this manner preferably have a stable roughness of 1.0 ?m<Rz<500 ?m, in particular Rz=5 ?m to 25 ?m.

  • Patent number: 7861869
    Abstract: A process for manufacturing asymmetric braid reinforced capillary ultra- or micro-filtration membranes (1), including the subsequent steps of pulling a tubular braid (5) through a spinneret (7) and coating the braid with a dope. Prior to the coating step, the braid is impregnated with a non-coagulation liquid, being a liquid which does not cause coagulation of the dope, when brought in contact with the dope. The result is a membrane with an outer skin, i.e. smaller pores near the outside diameter than near the inside diameter, and a coating which is closely arranged around the outside diameter of the braid, without any substantial penetration of the coating into the braid.

  • Publication number: 20100005969
    Abstract: An H2-permeable membrane system (117) comprises an electroless-deposited plating (115) of Pd or Pd alloy on a porous support (110, 110?). The Pd plating comprises face-centered cubic crystals cumulatively having a morphology of hexagonal platelets. The permeability to H2 of the membrane plating (115) on the porous support is significantly enhanced, being at least greater than about 1.3×10?8 mol·m?1·s?·Pa?0.5 at 350° C., and even greater than about 3.4×10?8 mol·m?1·s?1·Pa?0.5. The porous support (110, 110?) may be stainless steel (1100 and include a thin ceramic interlayer (110?) on which the Pd is plated. The method of providing the electroless-deposited plating includes preheating a Pd electroless plating solution to near a plating temperature substantially greater than room temperature, e.g. 60° C., prior to plating.

  • Patent number: 7402277
    Abstract: The present invention relates to a method of forming metallic foams using cold spray processing. The method allows for the formation of metallic foams on existing substrates as a layer. The method includes the steps of providing a substrate for coating of a metallic foam; cold spraying a mixture of metal particles and a foaming agent onto the substrate to form a substrate coated with an unexpanded metallic layer; foam heat treating the substrate coated with an unexpanded metallic layer at a temperature above the decomposition temperature of the foaming agent for a time sufficient to form a heated substrate coated with an expanded metal foam layer; and cooling the heated substrate coated with an expanded metal foam layer to about ambient temperature to form a cooled substrate coated with an expanded metal foam layer. The method of forming metallic foams on substrates finds application in the oil, gas, and chemical industry by being an integral part of casings, pipelines, transfer lines, and other flow lines.

    Abstract: An electrolytic electrode having an interlayer having more excellent peeling resistance and corrosion resistance and longer electrolytic life than conventional electrolytic electrodes and capable of flowing a large amount of current at the industrial level and a process of producing the same are provided. The electrolytic electrode includes a valve metal or valve metal alloy electrode substrate on the surface of which is formed a high-temperature oxidation film by oxidation, and which is coated with an electrode catalyst. The high-temperature oxidation film is integrated with the electrode substrate, whereby peeling resistance is enhanced.

  • Patent number: 7078361
    Abstract: This invention is an improved fuel cell design for use at low pressure. The invention has a reduced number of component parts to reduce fabrication costs, as well as a simpler design that permits the size of the system to be reduced at the same time as performance is being improved. In the present design, an adjacent anode and cathode pair are fabricated using a common conductive element, with that conductive element serving to conduct the current from one cell to the adjacent one. This produces a small and simple system suitable for operating with gas fuels or alternatively directly with liquid fuels, such as methanol, dimethoxymethane, or trimethoxymethane. The use of these liquid fuels permits the storage of more energy in less volume while at the same time eliminating the need for handling compressed gases which further simplifies the fuel cell system.
