Patent number: 7507382Abstract: A collection of zinc oxide nanoparticles have been produced by laser pyrolysis. The zinc oxide nanoparticles have average particle diameters of less than about 95 nm and a very narrow particle size distribution. The laser pyrolysis process is characterized by the production of a reactant stream within the reaction chamber, where the reactant stream includes a zinc precursor and other reactants. The zinc precursor can be delivered as an aerosol.Type: GrantFiled: October 3, 2001Date of Patent: March 24, 2009Assignee: NanoGram CorporationInventors: Hariklia Dris Reitz, Sujeet Kumar, Xiangxin Bi, Nobuyuki Kambe, Ronald J. Mosso, James T. Gardner

Publication number: 20080131357Abstract: Collections of particles comprising multiple a metal oxide can be formed with average particle sizes less than about 500 nm. In some embodiments, the particle collections have particle size distributions such that at least about 95 percent of the particles have a diameter greater than about 40 percent of the average diameter and less than about 160 percent of the average diameter. Also, in further embodiments, the particle collections have particle size distribution such that effectively no particles have a diameter greater than about four times the average diameter of the collection of particles.Type: ApplicationFiled: January 16, 2008Publication date: June 5, 2008Inventors: Sujeet Kumar, Hariklia Dris Reitz, Craig R.

Patent number: 6749966Abstract: Laser pyrolysis can be used to produce directly metal vanadium oxide composite nanoparticles. To perform the pyrolysis a reactant stream is formed including a vanadium precursor and a second metal precursor. The pyrolysis is driven by energy absorbed from a light beam. Metal vanadium oxide nanoparticles can be incorporated into a cathode of a lithium based battery to obtain increased energy densities. Implantable defibrillators can be constructed with lithium based batteries having increased energy densities.Type: GrantFiled: April 1, 2002Date of Patent: June 15, 2004Assignee: NanoGram Devices CorporationInventors: Hariklia Dris Reitz, James P. Buckley, Sujeet Kumar, Yu K. Fortunak, Xiangxin Bi

Publication number: 20030198590Abstract: A powder of lithiated manganese oxide has an average particle diameter preferably less than about 250 nm. The particles have a high degree of uniformity and preferably a very narrow particle size distribution. The lithiated manganese oxide can be produce by the reaction of an aerosol where the aerosol comprises both a first metal (lithium) precursor and a second metal (manganese) precursor. Preferably, the reaction involves laser pyrolysis where the reaction is driven by heat absorbed from an intense laser beam.Type: ApplicationFiled: May 13, 2003Publication date: October 23, 2003Applicant: NanoGram CorporationInventors: Sujeet Kumar, Hariklia Dris Reitz, Xiangxin Bi

Patent number: 6482374Abstract: Lithium manganese oxide particles have been produced with an average diameter less than about 250 nm. The particles have a high degree of uniformity. The particles can be formed by the heat treatment of nanoparticles of manganese oxide. Alternatively, crystalline lithium manganese oxide particles can be formed directly by laser pyrolysis. The lithium manganese oxide particles are useful as active materials in the positive electrodes of lithium based batteries. Improved batteries result from the use of uniform nanoscale lithium manganese oxide particles.Type: GrantFiled: June 16, 1999Date of Patent: November 19, 2002Assignee: NanoGram CorporationInventors: Sujeet Kumar, Hariklia Dris Reitz, Craig R.

Patent number: 6460417Abstract: This invention relates to methods for testing elongation and cracking of coating arrays. The method includes simultaneously applying an elongating force to each of a plurality of coatings, and monitoring the coating integrity including cracks and thickness decrease in each coating. A relative performance characteristic of each coating is then determined based on a correlation between a detected crack and/or thickness decrease in the coating, and the corresponding elongating force.Type: GrantFiled: August 24, 2001Date of Patent: October 8, 2002Assignee: General Electric CompanyInventors: Radislav Alexandrovich Potyrailo, Bret Ja Chisholm, Daniel Robert Olson, James Norman Cawse, Michael Matthew Laurin, George Frederic Medford, Hariklia Dris Reitz
