A device and method for separating water into hydrogen and oxygen is disclosed. A first substantially gas impervious solid electron-conducting membrane for selectively passing hydrogen is provided and spaced from a second substantially gas impervious solid electron-conducting membrane for selectively passing oxygen. When steam is passed between the two membranes at disassociation temperatures the hydrogen from the disassociation of steam selectively and continuously passes through the first membrane and oxygen selectively and continuously passes through the second membrane, thereby continuously driving the disassociation of steam producing hydrogen and oxygen.

A device and method for separating water into hydrogen and oxygen is disclosed. A first substantially gas impervious solid electron-conducting membrane for selectively passing protons or hydrogen is provided and spaced from a second substantially gas impervious solid electron-conducting membrane for selectively passing oxygen. When steam is passed between the two membranes at dissociation temperatures the hydrogen from the dissociation of steam selectively and continuously passes through the first membrane and oxygen selectively and continuously passes through the second membrane, thereby continuously driving the dissociation of steam producing hydrogen and oxygen. The oxygen is thereafter reacted with methane to produce syngas which optimally may be reacted in a water gas shift reaction to produce COand H.

A process for forming a palladium or palladium alloy membrane on a ceramic surface by forming a pre-colloid mixture comprising a powder palladium source, carrier fluid, dispersant and a pore former and a binder. Ultrasonically agitating the precolloid mixture and applying to a substrate with an ultrasonic nozzle and heat curing the coating form a palladium-based membrane.

A method for preparing a covetic, nanocarbon-infused, metal composite material is described is herein. The method comprises heating a stirring molten mixture of a metal (e.g., Cu, Al, Ag, Au, Fe, Ni, Pt, Sn, Pb, Zn, Si, and the like) and carbon (e.g., graphite) at a temperature sufficient to maintain the mixture in the molten state in a reactor vessel, while passing an electric current through the molten mixture via at least two spaced electrodes submerged or partially submerged in the molten metal. Each of the electrodes has an electrical conductivity that is at least about 50 percent of the electrical conductivity of the molten mixture at the temperature of the molten mixture. Preferably, the conductivity of the electrodes is equal to or greater than the conductivity of the molten mixture.

A method for making covetic metal-nanostructured carbon composites or compositions is described herein. This method is advantageous, in that it provides substantially oxygen-free covetic materials and allows precise control of the composition of the covetic material to be produced. The method comprises introducing carbon into a molten metal in a heated reactor under low oxygen partial pressure, while passing an electric current through the molten metal. The reactor is heated at a temperature sufficient to form a network of nanostructured carbon within a matrix of the metal. After heating the covetic material is recovered from the reactor.

The invention provides a dielectric-conductive substrate construct comprising a conductive material having a first surface and a second surface, and a dielectric film directly contacting the first surface and substantially covering the first surface, wherein the second surface is exposed to the ambient environment. Also provided is a method for producing a two component dielectric-conductive substrate, the method comprising supplying a base metal; and directly contacting a ceramic to the base metal to form a ceramic-metal interface while simultaneously preventing the formation of electrically insulative layers at the interface.
