    Abstract: A method of forming a nanowire is disclosed. In one embodiment, a primary preform is formed comprising at least one central region and a support structure. The primary preform is then drawn to a cane, which is then inserted into an outer portion, to form a secondary preform. The secondary preform is then drawn until the at least one central portion is a nanowire. The method can produce nanowires of far greater length than existing methods, and can reduce the likelihood of damaging the nanowire when handling.

  • Publication number: 20110020646
    Abstract: A method for producing a nanodiamond (n-diamond, p-diamond, i-carbon) in which a nanodiamond is removed from an activated carbon containing the nanodiamond. The activated carbon is prepared by carbonizing and/or activating a carbonaceous feedstock while restricting the presence of oxygen sufficiently to result in the formation of nanodiamonds embedded in carbon. The nanodiamonds can be separated and purified from the activated carbon, and can be concentrated by treatment of the activated carbon with an oxidizing agent. Also provided is a method for producing a nanodiamond, and particularly a nanodiamond fiber, by mixing a carbon source, a metal and an acid under conditions which result in nanodiamond formation. Nanodiamond fibers up to 2000 nanometers or more can be produced. The nanodiamond fibers can be woven or used to provide structural reinforcement for various materials.

  • Publication number: 20100233458
    Abstract: The present invention provides methods of making micron, submicron or nanometer dimension thermoplastic polymer microfibrillar composites and fibers, and methods of using the thermoplastic polymer microfibers and nanofibers in woven fabrics, biocidal textiles, biosensors, membranes, filters, protein support and organ repairs. The methods typically include admixing a thermoplastic polymer and a matrix material to form a mixture, where the thermoplastic and the matrix are thermodynamically immiscible, followed by extruding the mixture under conditions sufficient to form a microfibrillar composite containing a plurality of the thermoplastic polymer microfibers and/or nanofibers embedded in the matrix material. The microfibers and/or nanofibers are isolated by removing the surrounding matrix. In one embodiment, the microfibrillar composite formed is further extended under conditions sufficient to form a drawn microfibrillar and/or nanofibrillar composite with controlled diameters.
