Patent number: 7291318Abstract: A method is presented for effectively manufacturing multi-wall (double-wall, etc.) carbon nanotubes (CNTs) having a structure whereby interior tubes are formed within the CNTs. In this manufacturing method, fullerene/CNT hybrid structures are prepared, wherein assembled fullerenes, these being fullerenes that are linked, have been housed within single-wall CNTs.

Patent number: 6699450Abstract: A method for the manufacture of a structure from a carbide of a group IIa, group IIIa, group IVa, group IVb, group Vb, group VIb, group VIIb or group VIIIb carbon reactive element including the steps of: mixing the element with the carbon; and heating the carbon and the element to melt the element so that it reacts with the carbon to form the carbide; wherein, the carbon and element are heated by means of electromagnetic radiation having a frequency below the infrared spectrum. The method does not waste energy by unnecessary heating of the furnace or surrounding mold. The mold itself may be more stable because it is only heated by hot contained material and not by other sources of heat. Resulting formed products are not a sintered product and may approach one hundred percent of theoretical density. The carbon may be in the form of a powder that is mixed with the element or may be a porous carbon structure such as a graphite fiber mat or sheet into which the carbon reactive element is melted.Type: GrantFiled: March 19, 2001Date of Patent: March 2, 2004Assignee: Redunndant Materials, Inc.Inventors: Michael P.
