Advanced Catalyst System Prepared from a Whiskered Aluminum-Containing Metallic Alloy Substrate

A method for whisker formation on the surface of aluminum containing metallic 5 alloy fibers and substrates provides a support structure for many technical, medical and pharmaceutical applications. The novel surface modification of metallic alloy fibers and other metallic substrates involves heating the fiber or substrate in air at temperatures ranging from approximately 800°C to approximately 1000°C for a period of time ranging from approximately 10 hours to approximately 100 hours to form whiskers. The use of a 10 metal oxide coating with large ions, such as zirconium oxide, allows the formation of alumina whiskers while preserving the structural integrity of the metallic alloy substrate. Uses of the present invention include, but are not limited to an advanced catalyst support, a highly efficient filter medium, a support for implants and the like

Surfactant Incorporated Nanostructures for Pressure Drop Reduction in Oil and Gas Lines

Nano-sized rare earth metal oxide particles are prepared from aqueous reverse micelles. The engineered nanoparticles have large surface area to volume ratios, and uniformly incorporate a surfactant in each particle, so that when applied to the inner surface of a pipeline or sprayed onto a fluid stream in a pipeline, the particles reduce the roughness of the inside surface of pipe being used to transport fluid. The application of a nanolayer of this novel nanoceria mixture causes a significant reduction in pressure drops, friction, and better recovery and yield of fluid flowing through a pipeline

In-situ Synthesis of Carbon Nanotubes Filled with Metallic Nanoparticles Using Arc Discharge in Solution

A novel method for simultaneously forming and filling and decorating carbon nanotubes with palladium nanoparticles is disclosed. Synthesis involves preparing palladium chloride (PdCl2) solution in a container, having two graphite electrodes, then immersing the graphite electrode assembly, into the PdCl2 solution; connecting the graphite electrodes to a direct current power supply; bringing the electrodes into contact with each other to strike and arc; separating the electrodes to sustain the arc inside the solution; putting the container with the electrode assembly in a water-colled bath; and collecting Pd-nanoparticles encapsulated in carbon nanotubes and carbon nanotubes decorated with Pd-nanoparticles. The temperature at the site of the arc-discharge is greater than 3000 degrees C. At these temperatures, the palladium is ionized into nanoparticles and the graphite electrodes generate layers of graphene (carbon), which roll away from the anode and encapsulate or entrap the Pd-nanoparticles. The unique nanotube structures have significant commercial potential as gas sensors or as a means for hydrogen storage

Nanoparticles For Soot Reduction [Div]

Novel nano-sized rare earth metal oxide prepared from aqueous reverse micelles is provided. The engineered nanoparticles have large surface area to volume ratios, and sufficient oxygen vacancies on the surface of each particle, so that when mixed with carbon-containing combustible fuels, the particles remain suspended indefinitely; there is a significant reduction in soot and other by-products of combustion, an increase in engine efficiency and less fuel consumed per mile traveled in various vehicles, such as, but not limited to, automobiles, defense vehicles, airplanes, ships and other surface or air-bearing vehicles
