    Abstract: An apparatus and method to improve protection of a pre-coated substrate in various environments. The apparatus may include a pre-coated substrate having a substantially porous vapor-deposited coating and one or more non-porous ceramic oxide-based layers applied to the pre-coated substrate by a non-vapor deposition technique. The coefficient of thermal expansion corresponding to the non-porous ceramic oxide-based layer may substantially match the thermal expansion coefficient of the vapor-deposited coating to facilitate thermal compatibility between the two. Further, the non-porous ceramic oxide-based layer may infiltrate pores of the substantially porous vapor-deposited coating to provide a well-bonded hermetic seal that limits fluid access to the pre-coated substrate through the substantially porous vapor-deposited coating.

    Abstract: A process for treating fly ash to render it highly usable as a concrete additive. A quantity of fly ash is obtained that contains carbon and which is considered unusable fly ash for concrete based upon foam index testing. The fly ash is mixed with a quantity of spray dryer ash (SDA) and water to initiate a geopolymerization reaction and form a geopolymerized fly ash. The geopolymerized fly ash is granulated. The geopolymerized fly ash is considered usable fly ash for concrete according to foam index testing. The geopolymerized fly ash may have a foam index less than 40%, and in some cases less than 20%, of the foam index of the untreated fly ash. An optional alkaline activator may be mixed with the fly ash and SDA to facilitate the geopolymerization reaction. The alkaline activator may contain an alkali metal hydroxide, carbonate, silicate, aluminate, or mixtures thereof.

    Abstract: A method for joining multiple ceramic components together is disclosed in one embodiment of the invention as including providing multiple ceramic components, each having a mating surface. A slip containing a mixture of alumina powder and a phosphate-containing reagent is applied to one or more of the mating surfaces. The mean particle size of the alumina powder is tailored to provide improved strength to the bond. Once the slip is applied, the ceramic components may be joined together at their mating surfaces. The joint may then be sintered to react the constituents in the mixture and thereby generate a bond between the ceramic components.

    Abstract: An apparatus for providing beneficial agents to the body is disclosed in one aspect of the invention as including an implant and a device integrated with the implant to generate a beneficial agent, such as iodine, chlorine, or other halogens. The device includes electrodes to conduct an electrical current and a substantially solid layer between the electrodes. An electrical current passes between the electrodes to electrochemically generate the beneficial agent. The implant may include a variety of devices to produce the beneficial agent, including for example an electrochemical cell, a capacitor, an electrochemical capacitor, a galvanic cell, or the like. Similarly, because of the solid state construction of the device, the device may, in certain embodiments, be incorporated into a load-bearing implant. This may be useful for use with certain types of implants, such as orthopedic implants.
