Embodiments of a high temperature electromagnetic coil assembly are provided, as are embodiments of a method for fabricating such a high temperature electromagnetic coil assembly. In one embodiment, the high temperature electromagnetic coil assembly includes a coiled anodized aluminum wire and an electrically-insulative, high thermal expansion ceramic body in which the coiled anodized aluminum wire is embedded. The electrically-insulative, high thermal expansion ceramic body has a coefficient of thermal expansion greater than 10 parts per million per degree Celsius and less than the coefficient of thermal expansion of the coiled anodized aluminum wire.

High temperature electromagnetic coil assemblies

Embodiments of a high temperature electromagnetic coil assembly are provided, as are embodiments of a method for fabricating such a high temperature electromagnetic coil assembly. In one embodiment, the method includes the steps of applying a high thermal expansion ceramic coating over an anodized aluminum wire, coiling the coated anodized aluminum wire around a support structure, and curing the high thermal expansion ceramic coating after coiling to produce an electrically insulative, high thermal expansion ceramic body in which the coiled anodized aluminum wire is embedded.

Methods for fabricating high temperature electromagnetic coil assemblies

An apparatus and method to electrocatalytically induce the decomposition of a liquid propellant for propulsion. This is accomplished by providing a reaction chamber filled with catalyst that has a first electrode, such as near the center, and the other electrode disposed away from the first electrode. A charge source that is capable of applying voltage is connected to the electrodes. When the reaction chamber is dosed with a propellant such as an aqueous based amine propellant, such as HAN, an electric current flows between the electrodes and the propellant. This initiates the decomposition of the propellant which is driven to completion by the catalyst bed in order to be used for power generation.

A method for purifying breathing air using a carbon-based monolith structure impregnated with copper, silver, zinc, and molybdenum species and triethylenediamine, wherein the monolith structure is impregnated by a multiple step process. The method of impregnation results in a carbon-based monolith structure that purifies nuclear, biological, or chemical contaminants under conditions of high flow rate and low pressure drop.

A titania bound ion exchange composition is prepared by admixing crystalline sodium titanate and a hydrolyzable titanium compound and then drying the titania bound crystalline sodium titanate. The dried titania bound ion exchange composition is subjected to optional compaction and calcination steps to improve the physical strength of the titania bound composition.

A hydrophilic antimicrobial coating includes a porous ceramic-based coating and at least one biocide dispersed in the porous, hydrophilic ceramic-based coating. The coating can be an alumina coating, and the biocide can include silver oxide. A second biocide such as zinc oxide or copper oxide can also be dispersed in the porous, hydrophilic ceramic-based coating. The hydrophilic antimicrobial coating can be applied to a heat transfer surface of a heat exchanger.
