摘要： A system comprises a processing chamber for maintaining a hydrogen plasma at low pressure. The processing chamber has a long, wide, thin geometry to favor deposition of thin-film silicon on sheet substrates over the chamber walls. The sheet substrates are moved through between ends. A pair of opposing radio frequency electrodes above and below the workpieces are electrically driven hard to generate a flat, pancaked plasma cloud in the middle spaces of the processing chamber. A collinear series of gas injector jets pointed slightly up on a silane-jet manifold introduce 100% silane gas at high velocity from the side in order to roll the plasma cloud in a coaxial vortex. A second such silane-jet manifold is placed on the opposite side and pointed slightly down to further help roll the plasma and maintain a narrow band of silane concentration. A silane-concentration monitor observes the relative amplitudes of the spectral signatures of the silane and the hydrogen constituents in the roll-vortex plasma and outputs a process control feedback signal that is used to keep the silane in hydrogen concentration at about 6-7%.

摘要： A system for large scale capture of atmospheric carbon dioxide while exposed to air and weather in an outdoor environment, includes a large flat slab with a perimeter wall projecting above its surface; one or more rotary fans, providing uniform, high volume, low velocity, turbulent air flow over the entire slab surface; a transport system transferring powder—a particulate material mixed with air—to and from all locations on the slab or on an overlying mesh screen, a kiln, closed to outside air, and a compressor. The transport system includes either a vacuum/deposition system or a conveyor system with one or more conveyors. The kiln heats the particulate material, delivered by the transport system from the slab, to output released carbon dioxide, previously absorbed by the particulate material in the powder, to the compressor for compression, and either the heated particulate material, or a processed version of it.

The metal may be selected from the group consisting of beryllium, titanium, hafnium and zirconium. At least a first portion of the metal may be present in un-oxidized form at the entrance to and/or within grain boundaries within the fiber.A method of improving at least one of the strength, creep resistance, and toughness of a fiber comprises adding to a fiber, initially comprising a bulk material having a first affinity for oxygen, a metal that has a second affinity for oxygen higher than the first affinity. The metal may be selected from the group consisting of beryllium, titanium, hafnium and zirconium.

摘要： An apparatus comprises a separator, a compressor, a mixer and a pump. The separator operates on an input gas mixture comprising carbon dioxide gas and one or more other gases, providing a separated carbon dioxide gas output. A compressor compresses the separated carbon dioxide gas output, providing a second output comprising at least one of gaseous carbon dioxide and liquid carbon dioxide. A mixer mixes the second output with liquid water under pressure to provide a third output comprising: at least one of liquid carbon dioxide and gaseous carbon dioxide; and water with dissolved carbon dioxide. A pump pumps the third output into an underground structure such that components of the third output react with available rock surfaces to form stable carbonates.

摘要： A lithium battery includes a solid cathode and a solid electrolyte (SSE), wherein a structurally continuous block of material comprises the solid cathode and the SSE. The structurally continuous solid block of material has a first chemical composition in the solid cathode and a second chemical composition, different from the first chemical composition, in the SSE. The SSE overlies the solid cathode, without any physical separation or interface therebetween.
A method for fabricating a lithium battery includes placing a first layer of particles of an electrolyte material of a first composition on top of a second layer of particles of a cathode material of a second composition, forming a stack; and compressing and heating the stack of first and second layers to form a continuous solid material. The formed material has a solid electrolyte (SSE) characterized by the first composition and a solid cathode characterized by the second composition.-

摘要： Embodiments generally relate to long-distance, 3-phase, AC electricity transmission structures. In one embodiment, the structure comprises an array of beams, the array comprising a sub-array of 3N active beams, wherein N is an integer, one passive beam on the right side of the sub-array of active beams; and one passive beam on the left side of the sub-array of active beams. The centers of the cross-section of each of the active and passive beams lie in a single plane. In another embodiment, the structure comprises an array of 3N metal active beams, wherein N is an integer; and a tunnel of rectangular cross-section with either 90 degree or rounded corners. The array of beams is mounted within the tunnel, and the two side walls of the tunnel are lined with a highly conductive metal having a thickness similar to the thickness of metal used in the active beams.

摘要： A fiber comprises a bulk material comprising: one or more of carbon, silicon, boron, silicon carbide, and boron nitride; and a metal or metal alloy whose affinity for oxygen is greater than that of the bulk material. At least a first portion of the metal or metal alloy is present at the entrance to grain boundaries at the surface of the fiber and within the fiber to a depth of at least 1 micron from the fiber surface.
A method of improving a fiber comprises heating a fiber in an inert atmosphere to 900-1300 C for sufficient time to allow at least some of a metal or metal alloy, placed on the fiber, to diffuse and/or flow into and along grain boundaries to a depth of at least 1 micron. The metal or metal alloy has a greater affinity for oxygen than that of the fiber bulk material.
