| 20110073344 | GASKET CONTAINING CARBON NANOTUBES - A composition for forming a gasket comprises a curable elastomer material and 0.1-20 weight % (e.g., 4-10 weight %) carbon nanotubes dispersed throughout the elastomer material. A dispensed bead of elastomer material exhibits a Slump ratio of at least 0.7. The composition provides the correct balance of rheology/dispensing characteristics, seal characteristics, and contamination profile characteristics required in form-in-place gasket applications, while simultaneously providing a conductive form-in-place gasket. | 03-31-2011 |
| 20110002838 | METHOD FOR PREPARING SINGLE WALLED CARBON NANOTUBES FROM A METAL LAYER - Methods of preparing single walled carbon nanotubes are provided. An arrangement comprising one or more layers of fullerene in contact with one side of a metal layer and a solid carbon source in contact with the other side of metal layer is prepared. The fullerene/metal layer/solid carbon source arrangement is then heated to a temperature below where the fullerenes sublime. Alternatively, a non-solid carbon source may be used in place of a solid carbon source or the metal layer may simply be saturated with carbon atoms. A multiplicity of single walled carbon nanotubes are grown on the fullerene side of the metal layer, wherein at least 80% of the single walled carbon nanotubes in said multiplicity have a diameter within ±5% of a single walled carbon nanotube diameter D present in said multiplicity, said diameter D being in the range between 0.6-2.2 nm. | 01-06-2011 |
