Abstract: A device can be used as an electrode for a lithium-ion battery. The device comprises an electrically conductive substrate to the surface of which nanofilaments having an ion-absorbing coating are applied. The nanofilaments are combined by the application of light into a plurality of bundles, each having multiple nanofilaments. A spacer gap is formed between neighboring bundles.

Abstract: A device for transporting a strip-type substrate through a reactor includes transport elements for holding the substrate. The transport elements are displaceable by a drive unit in a transport direction. The transport elements have first transport beams and second transport beams that engage in alternation on the substrate, in which the transport beams that engage the substrate move in the transport direction and the transport beams that do not engage the substrate move in a reverse direction opposite to the transport direction. The device further includes transport carriages that are arranged in pairs in the transport direction respectively upstream and downstream of the reactor.

Abstract: A high voltage diamond based switching device capable of sustaining high currents in the on state with a relatively low impedance and a relatively low optical switching flux, and capable of being switched off in the presence of the high voltage being switched. The device includes a diamond body having a Schottky barrier contact, held in reverse bias by the applied voltage to be switched, to an essentially intrinsic diamond layer or portion in the diamond body, a second metal contact, and an optical source or other illuminating or irradiating device such that when the depletion region formed by the Schottky contact to the intrinsic diamond layer is exposed to its radiation charge carriers are generated. Cain in the total number of charge carriers then occurs as a result of these charge carriers accelerating under the field within the intrinsic diamond layer and generating further carriers by assisted avalanche breakdown.

Abstract: Nano-technology is an emerging and intensely competitive field. There are a number of companies that work mainly in the development of various Nano-technology areas. One area that has not received too much emphasis is that of specialized equipment for Nano-technology. Nanoinstruments is a company working to rectify this deficiency in the field of nano-material deposition, especially in Carbon Nanotube and Nanowire growth. A number of innovations disclosed include the use of a low thermal mass heating unit that allows fast changes in temperature of the growth sample while providing sufficient thermal stability, uniformity and electrical isolation, a novel shower head design for providing uniform gas flow while eliminating thermal and plasma decomposition of feed stock at the nozzle, a pulsed voltage waveform that eliminates charging of substrate on which the growth has to take place, and the use of a conductive grid over insulating substrates to achieve uniform plasma over the growth surface.

Abstract: An energy storage device structure comprises a first electrode layer, an electrolyte layer and a second electrode layer. At least one of the electrode layers comprise a metallic base layer and a layer of carbon nanotubes grown on the base layer, the carbon nanotube layer being arranged to face the electrolyte layer. The structure has much larger width and length than thickness, so it is rolled up or folded and then hermetically sealed to form an energy storage unit. The layer of carbon nanotubes is grown on the metallic base layer by a chemical vapor deposition process at a temperature no higher than 550° C. The carbon nanotubes in the carbon nanotube layer are at least partially aligned in a direction that is perpendicular to the surface of the metallic base layer.
