  • Liquid feed flame spray modification of nanoparticles
    Patent number: 7700152
    Abstract: Nano- and micron sized metal oxide and mixed metal oxide particles are injected into a high temperature region wherein the temperature is between about 400° C. and less than 2000° C., and collected as particles or as coatings wherein a particulate nature is substantially maintained. The particles are altered in at least one of phase, morphology, composition, and particle size distribution, and may achieve further changes in these characteristics by coinjection of metal oxide precursor in liquid form.
    Type: Grant
    Filed: February 25, 2005
    Date of Patent: April 20, 2010
    Assignee: The Regents of the University of Michigan
    Inventors: Richard M. Laine, Julien Marchal, José Azurdia, Roy Rennesund

  • Process for tagging of manufactured articles with up-and down-converting metal oxide nanophosphors and articles produced thereby
    Publication number: 20050112360
    Abstract: Manufactured articles are rendered identifiable as to their source or genuineness by incorporating one or more populations of up- and/or down-converting metal oxide or mixed metal oxides during or post manufacture. The nanoparticles exhibit emission of light upon irradiation by energy sources which allows comparison between the emission spectrum of an article with the emission expected of a genuine article or a material from a given manufacturing process, i.e. a batch of material.
