Abstract: Methods and compositions are described for the preparation of piezoelectric ceramic-polymer composites having improved properties for application in piezoelectric devices. These composites consist of piezoelectric particles embedded in a polymer matrix. The improvements of this invention result from discoveries of the effects of particle size, particle size dispersity, volumetric loading levels, ceramic dielectric constant, and polymer dielectric constant on performance. Various improved devices based on these compositions are also described.

Abstract: A corrosion resistant coated fuel cell plate and method of making the same are embodied in a metal plate (400) provided with a graphite emulsion coating (402) and then a layer (406) of graphite foil which is pressed over the coating (402). The graphite emulsion (402) bonds the graphite foil (406) to the metal plate (400) and seals fine scale porosities (410) in the graphite foil (406). Flow fields (414) are formed by stamping the coated fuel cell plate.

Abstract: La présente invention se rapporte à une amélioration apportée à un procédé de formation de dépôts de céramiques supraconductrices. De telles céramiques sont généralement formées par électrodéposition d'un mélange de métaux du type supraconducteur dans des proportions suffisantes pour en faire par oxydation une substance céramique; par oxydation du mélange électrodéposé dans des conditions suffisantes pour produire un dépôt céramique supraconducteur; et par orientation des cristallites dans le dépôt céramique supraconducteur. L'orientation des cristallites peut être effectuée avant, après ou pendant la phase d'oxydation.

Abstract: This invention relates to compositions and processes for the fabrication of piezoelectric composites having improved figures of merit for both sensor and non-sensor applications. These composites comprise piezoelectric particles embedded in a polymer matrix. The improvements of this invention result from discoveries of the effects of polymer bulk compliance, polymer anisotropy, polymer melt index, and polymer/ceramic wettability on performance. The loss corrected figure of merit (ghdh/tanδ) obtained for the 0-3 composites is as high as 10.5 x 10-10 m2/N, which is about four times higher than previously published for 0-3 composites of the prior art. Methods are described for the introduction of anisotropy into ceramic particle/polymer composites, so that cancellation effects that degrade the piezoelectric properties of composites can be reduced.

Abstract: The invention relates to an improvement in a method of forming deposits of superconducting ceramics. Generally, such ceramics are formed by electrodepositing a mixture of metals of the type and in proportions sufficient to be oxidized into ceramic; oxidizing the electrodeposited mixture under conditions sufficient to result in a superconducting ceramic deposit; and orienting the crystallites in said superconducting ceramic deposit. Crystallite orientation may take place before, after or during the oxidation step.
