- Description
- NASA�s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.�NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: NASA's Langley Research Center scientists originally developed a Free Electron Laser (FEL) Ablation technique to synthesize single-walled carbon nanotubes. FEL provides a vast improvement over other techniques employed to make carbon nanotubes. The nanotubes produced by FEL are very pure, straight, homogenous, and defect-free. Most notable is that these nanotubes can be produced in much larger quantities than by other laser-based techniques. Now NASA scientists have further provided incremental improvement in this technology by creating a recipe and procedure for the inexpensive and simple production of fine-grained targets required for the synthesis of carbon nanotubes using FEL. Previously used targets employed metal powders that did not have a particularly small grain size or small size dispersibility. The targets used here are made of powder forge metals that are both small and dispersible. The targets facilitate a significant cost reduction in the supply of high-quality single-walled carbon nanotubes. The fine-grained targets are a matrix of a prismatic edge natural flake graphite that produces strong structural pi bonds when pressed at room temperature. The targets have an approximate grain size of 2 microns. The graphite provides a carbon source that is combined with a metal catalyst made of powder forge nickel and powder forge cobalt. Previously used targets involved pressing and binding targets with Dylon carbon cement. These particles had an approximate 200-micron particle size, which led to large regions of uncatalyzed target. The new metal powders are small (~0.5 microns), highly dispersible, and two orders of magnitude less expensive. The powders are mixed in appropriate quantities and subjected to low-energy ball-milling to ensure mingling. Targets undergo additional preparatory steps, including high pressure processing. The targets are then subjected to a series of ultrafast infrared laser light pulses at a high repetition rate to vaporize the layers of the spinning targets and create a plume of nanotubes. To express interest in this opportunity, please submit a license application through NASA�s Automated Technology Licensing Application System (ATLAS) by visiting�https://technology.nasa.gov/patent/LAR-TOPS-67 If you have any questions, please e-mail NASA�s Technology Transfer Program at�Agency-Patent-Licensing@mail.nasa.gov�with the title of this Technology Transfer Opportunity as listed in this SAM.gov notice and your preferred contact information. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at�https://technology.nasa.gov/ These responses are provided to members of NASA�s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.�No follow-on procurement is expected to result from responses to this Notice.
