This invention is a composition of matter useful as a compression-ignition fuel. The composition has from about 30 to about 95 mass % of a light synthetic crude or syncrude, preferably from Fischer-Tropsch synthesis or related processes, and from about 5 to about 70 mass % of a blending stock that improves one or more desirable fuel property(s) including but not limited to pour point temperature, viscosity and emissions generated during combustion in a diesel engine. The blend stock preferably has an average molecular weight less than the average molecular weight of the light syncrude. Preferred blending stocks include hydrocarbons and oxygenates, such as alcohols, and ethers, having average molecular weights less than 200, preferably less than 160. The composition may optionally also contain pour point depressants, cetane improvers, carbon-containing compounds which react with water, and/or emulsifiers.

Fuel cell elements: fuel, product, membrane, cathode and anode are operated within supercritical fluids (SCFs) to increase electrical and chemical-reaction efficiencies magnitudes more than prior art operating below the critical point of gas, liquids, and solids. Within vessel (4), cylinder (8) of vessel (3) is a polymer electrolyte membrane (PEM) dual- function reversible or unitized regenerative fuel cell (URFC) system. Rod (11) and rod (14) are electrically connected to the cathode and anode inside the vessels through separate circuits formed from electrically insulated vacuum seals (1) and (2). SCF has nearly 100 percent solvent penetration into the PEM membrane and acts as a single miscible fluid formed from multiple fluid species (including xenon) improving the rate of water decomposition (process water) when in the electrolyzer mode, and when reversed into the fuel cell mode, a higher rate of electricity is produced, a higher rate of electricity is produced across the membrane during power generation. Injector bores (12) and (15) can inject fuel into the SCF. Xenon gas with a high rate of polarization strings the electrical potential from the PEM circuit elements through the three dimensional suspension of xenon to the product or fuel. PEM membranes and SCFs are phosphorus-doped (N-type) on top of a thicker layer of boron-doped membrane, enabling photovoltaic and thermoelectric functions. Only photons whose energy is equal to or greater than the band gap of solar cell material can kick an electron up into the conduction band. Prior art photovoltaic response of single junction cells is limited to the portion of the sun's spectrum whose energy is above the band gap of the absorbing material, which means lower- energy photons are not used. Without solar cell circuit gaps, xenon absorbs all of the sun's photon spectrum passing through an outer transparent vessel (4). Thermoelectric energy is captured by decomposing water suspended in multiple SCFs tuned with co-solvents that are heat reactive.

The invention relates to a solid oxide fuel cell which comprises a solid electrolyte comprised of an electronic insulator which allows transfer of anions, a ceramic-metal composite anode and a cathode. The fuel cell also comprises a sulfur-containing hydrocarbon fuel having a sulfur content of from about 1 ppm to about 5000 ppm and an oxygen source. The invention further relates to a process of producing electrical energy with the fuel cell and a process of restoring the operability of a fuel cell that was deactivated by sulfur poisoning. The invention also relates to a method for preparation of a porous cermet as a direct-oxidation anode with supported electrolyte structure for a solid-oxide fuel cell using a nickel cermet. The nickel cermet is leached to remove at least part of the nickel, thereby producing a porous oxide. The resulting porous oxide is then impregnated, preferably with a salt of copper, which is calcined to CuO, then reduced to elemental copper. The resulting copper cermet or copper-nickel alloy cermet can be used as the direct-oxidation anode. The starting material for the nickel cermet is preferably a tape formed from a slurry comprising NiO and a ceramic powder comprising YSZ. This tape is combined into an assemblage with one or two additional tapes cast from a slurry comprising a ceramic powder. The invention further relates to a solid-oxide fuel cell comprising an anode material with supported electrolyte structure made by this method and a process for producing electrical energy using this fuel cell.

摘要:
A passive memory device (2) includes a plurality of resonant members (3), e.g. of a cantilever or bridge-type form, that may have different resonant frequencies and that may be held against vibrations by end or side tethers (4). Data may be recorded in the device (2) by removing various of the tethers (4), so that, on applying an excitation signal, e.g. from a transmitter (5), untethered resonant members (3) vibrate strongly in response to their resonant frequencies, and provide a response signal that can be picked up e.g. by a receiver (6) and correlated with the excitation signal frequencies to determine which resonant members (3) have been untethered. The response by an untethered resonant member can correspond to a logical "1", whilst the lack of a response signal at a known resonant member frequency can correspond to a logical "0", or vice versa. The device may be made using MEMS technology, and various device structures and excitation/detection methods are disclosed including the use of excitation/detection circuitry within the device and the use of magnetic, Lorentz, electrostatic and/or piezoelectric forces.
