Abstract: The invention features methods of producing a plant or a mature somatic embryo from an embryogenic cell or embryogenic culture. The method includes the steps of: (a) providing a liquid culture that includes an embryogenic cell; (b) recovering embryogenic cell from the culture; (c) transferring the embryogenic cell to a second culture; and (d) growing a mature somatic grape embryo from the embryogenic cell.

Abstract: Methods and cement compositions are provided for sealing a subterranean zone penetrated by a wellbore, wherein the cement composition comprises zeolite, cementitious material, and a mixing fluid.

Abstract: The present invention is directed to bidirectional promoter complexes that are effective for enhancing transcriptional activity of transgenes. The bidirectional promoters of the invention include a modified enhancer region with at least two core promoters on either side of the modified enhancer in a divergent orientation.

Abstract: A nanocomposite comprising a plurality of nanoparticles dispersed in a metallic alloy matrix, and a structural component formed from such a nanocomposite. The metallic matrix comprises at least one of a nickel-based alloy and an iron-based alloy. The nanocomposite contains a higher volume fraction of nanoparticle dispersoids than those presently available. The structural component include those used in hot gas path assemblies, such as steam turbines, gas turbines, and aircraft turbine. A method of making such nanocomposites is also disclosed.

Abstract: Erosion resistant coating compositions include hard particles in a metal matrix such as nickel-based, cobalt-based and iron-based matrices applied by a plating process for complex geometry or hard to access component surfaces or by thermal spray processes for line of sight applications. These materials and processes are especially suited for providing erosion resistance to hydroelectric turbine components.

Abstract: Erosion resistant coating processes and material improvements for line-of-sight applications. The erosion resistant coating composition includes nanostructured grains of tungsten carbide (WC) and/or submicron sized grains of WC embedded into a cobalt chromium (CoCr) binder matrix. A high velocity air fuel thermal spray process (HVAF) is used to create thick coatings in excess of about 500 microns with high percentages of primary carbide for longer life better erosion resistant coatings. These materials and processes are especially suited for hydroelectric turbine components.

Abstract: Nano-multilayered structures, components and associated methods of manufacture suitable for use in high-temperature applications including a plurality of metallic alloy layers, wherein the thickness of each of the plurality of metallic alloy layers is on a nano scale, and a plurality of ceramic oxide layers disposed between the plurality of metallic alloy layers in an alternating manner, wherein the thickness of each of the plurality of ceramic oxide layers is on a nano scale.
