  • Patent number: 9012366
    Abstract: A device for the high pressure densification of superconducting wire from compacted superconductor material or superconductor precursor powder particles, has four hard metal anvils (5, 6, 7, 8) with a total length (L2) parallel to the superconducting wire, the hard metal anvils borne in external independent pressure blocks (9, 10, 11), which are in turn either fixed or connected to high pressure devices, preferably hydraulic presses. At least one of the hard metal anvils is a free moving anvil (6) having clearances of at least 0.01 mm up to 0.2 mm towards the neighboring hard metal anvils (5, 8), so that no wall friction occurs between the free moving anvil and the neighboring anvils. This allows for high critical current densities Jc at reduced pressure applied to the hard metal anvils.

  • Patent number: 8992799
    Abstract: A polymer composite composed of a polymerized mixture of functionalized carbon nanotubes and monomer which chemically reacts with the functionalized nanotubes. The carbon nanotubes are functionalized by reacting with oxidizing or other chemical media through chemical reactions or physical adsorption. The reacted surface carbons of the nanotubes are further functionalized with chemical moieties that react with the surface carbons and selected monomers. The functionalized nanotubes are first dispersed in an appropriate medium such as water, alcohol or a liquefied monomer and then the mixture is polymerized. The polymerization results in polymer chains of increasing weight bound to the surface carbons of the nanotubes. The composite may consists of some polymer chains imbedded in the composite without attachment to the nanotubes.
