Patent number: 8052951Abstract: Disclosed are structures formed as bulk support media having carbon nanotubes formed therewith. The bulk support media may comprise fibers or particles and the fibers or particles may be formed from such materials as quartz, carbon, or activated carbon. Metal catalyst species are formed adjacent the surfaces of the bulk support material, and carbon nanotubes are grown adjacent the surfaces of the metal catalyst species. Methods employ metal salt solutions that may comprise iron salts such as iron chloride, aluminum salts such as aluminum chloride, or nickel salts such as nickel chloride. Carbon nanotubes may be separated from the carbon-based bulk support media and the metal catalyst species by using concentrated acids to oxidize the carbon-based bulk support media and the metal catalyst species.Type: GrantFiled: April 3, 2009Date of Patent: November 8, 2011Assignee: UT-Battelle, LLCInventors: Paul A. Menchhofer, Frederick C. Montgomery, Frederick S. Baker

Patent number: 6899827Abstract: Sintered, translucent ceramic microbeads, preferably alumina, titania, zirconia, yttria, zirconium phosphate, or yttrium aluminum garnet (YAG) are doped with one or more optically active species. The beads may be added to substances such as explosives in order to create a distinctive optical signature that identifies a manufacturer, lot number, etc. in the event of the need for forensic analysis. Because the beads have a generally spherical surface, the radius of curvature provides an additional distinguishing characteristic by which a particular sample may be identified. The beads could also be formulated into paints if needed to create distinctive optical signatures for camouflage, decoys, or other countermeasures and could also be applied as a dust to track the movement of personnel, vehicles, etc.Type: GrantFiled: May 16, 2003Date of Patent: May 31, 2005Assignee: UT-Battelle, LLCInventors: Robert J. Lauf, Kimberly K. Anderson, Frederick C. Montgomery

Patent number: 6821474Abstract: The invention allows the fabrication of small, dense beads of dielectric materials with selected compositions, which are incorporated into a polymeric matrix for use in capacitors, filters, and the like. A porous, generally spherical bead of hydrous metal oxide containing titanium or zirconium is made by a sol-gel process to form a substantially rigid bead having a generally fine crystallite size and correspondingly finely distributed internal porosity. The resulting gel bead may be washed and hydrothermally reacted with a soluble alkaline earth salt (typically Ba or Sr) at elevated temperature and pressure to convert the bead into a mixed hydrous titanium- or zirconium-alkaline earth oxide while retaining the generally spherical shape. Alternatively, the gel bead may be made by coprecipitation. This mixed oxide bead is then washed, dried and calcined to produce the desired (BaTiO3, PbTiO3, SrZrO3) structure. The sintered beads are incorporated into a selected polymer matrix.Type: GrantFiled: March 18, 2003Date of Patent: November 23, 2004Assignee: UT-Battelle, LLCInventors: Robert J. Lauf, Kimberly K. Anderson, Frederick C. Montgomery, Jack L. Collins, John J. Felten
