Patent number: 8323742Abstract: 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.Type: GrantFiled: November 22, 2010Date of Patent: December 4, 2012Assignee: Cellaris LimitedInventors: Gideon Grader, Gennady Shter, Yoram Dehazan

Publication number: 20120258587Abstract: Methods of forming a graphene material on a surface are presented. A metal material is disposed on a material substrate or material layer and is infused with carbon, for example, by exposing the metal to a carbon-containing vapor.

Publication number: 20100034974Abstract: A method for hard-material coating or heat treatment of the blade airfoils of blisks for gas turbines provides for partial heat-insulation and cooling of the other blisk parts during the respective process to prevent their properties from being changed by the high temperatures. The apparatus required for this method comprises two or more cooling plates (5 to 7) which are thermally insulated on their outer surfaces and include supporting flanges (20) which heat-conductively locate the blade platforms (3) of the blisks (1). Radially extending cooling medium channels (16) are provided in the cooling plates connected to a cooling medium source to continually apply cooling medium to the inner surfaces of the supporting flanges and the blade platforms.Type: ApplicationFiled: July 17, 2008Publication date: February 11, 2010Inventor: Rainer Mielke

Patent number: 7651753Abstract: A process for coating a carrier body, in particular a honeycomb body through which a fluid can flow, with a coating material which is applied to the carrier body, provides a spatial temperature distribution of the coating material in the carrier body being inhomogeneous during application and/or after application. A carrier body has a spatially inhomogeneous coating thickness and an apparatus is provided for the inhomogeneous coating of a carrier body. Efficient catalysis is ensured and superfluous coating material is saved at locations where it is not required.Type: GrantFiled: January 5, 2005Date of Patent: January 26, 2010Assignees: Emitec Gesellschaft fuer Emissionstechnologie mbH, Audi AktiengesellschaftInventors: Rolf Brück, Bodo Odendall, Bernhard Pfalzgraf

Publication number: 20090301879Abstract: A protective coating sustains the long term performance of a solid-state hydrogen sensor that includes a catalyst layer for promoting the electrochemical dissociation of hydrogen. The catalyst is susceptible to deterioration in the presence of at least one contaminant, including carbon monoxide, hydrogen sulfide, chlorine, water and oxygen. The coating comprises at least one layer of silicon dioxide having a thickness that permits hydrogen to diffuse to the catalyst layer and that inhibits contaminant(s) from diffusing to the catalyst layer. The preferred coating further comprises at least one layer of a hydrophobic composition, preferably polytetrafluoroethylene, for inhibiting diffusion of water through the protective coating to the catalyst layer. The preferred protective coating further comprising at least one layer of alumina for inhibiting diffusion of oxygen through the protective coating to said catalyst layer.Type: ApplicationFiled: April 6, 2009Publication date: December 10, 2009Inventors: Prabhu Soundarrajan, An T.

Publication number: 20090263671Abstract: Ferroelectric Poly(vinylidene fluoride) Film on a Substrate and Method for its Formation A method of producing a poly(vinylidene fluoride) (“PVDF”) film on a substrate from a precursor solution is disclosed. The method comprises preparing the precursor solution for the PVDF film and dissolving an additive in the precursor solution, the additive being selected from the group consisting of: a hydrate salt, and a hygroscopic chemical. The PVDF is added to the precursor solution. The PVDF solution is coated on a substrate to form an as-deposited PVDF film which is dried and crystallized at an elevated temperature. The dried and crystallized as-deposited PVDF film is annealed at a further elevated temperature. The further elevated temperature is greater than the elevated temperature but less than a melting point of the as-deposited PVDF film. The additive dehydrates at the further elevated temperature. A corresponding product is also disclosed.Type: ApplicationFiled: April 21, 2008Publication date: October 22, 2009Inventors: Kui Yao, Shuting Chen, Francis Eng Hock Tay

Patent number: 7563486Abstract: Systems and methods for designing and fabricating multi-layer structures having thermal expansion properties are provided. One embodiment provides a multi-layer structure comprising a central layer, a first layer, and a second layer. The first layer is constrained to a first side of the central layer and has a first thickness. The first layer comprises a first material having a first value for a thermal expansion property. The second layer is constrained to a second side of the central layer and has a second thickness. The second layer comprises a second material having a second value for a thermal expansion property. The second thickness and the second value for the thermal expansion property and the first thickness and the first value for the thermal expansion property are such that, upon a change in temperature, the net change in the strain energy in the first layer and the net change in the strain energy in the second layer are substantially equal.Type: GrantFiled: July 11, 2006Date of Patent: July 21, 2009Assignee: Avago Technologies General IP (Singapore) Pte.
