摘要： 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.

摘要： Methods for producing metal/metalloid oxide particles comprise rare earth metals herein include reacting a reactant stream in a gas flow. The reactant stream includes a rare earth metal precursor and an oxygen source. A collection of particles comprising metal/metalloid oxide have an average particle size from about 15 nm to about 1 micron. The metal/metalloid oxide comprises a non-rare earth metal oxide wherein less than about 25 percent of a non-rare earth metal is substituted with a rare earth metal. The particles are useful as phosphors, for example for use in displays.

摘要： 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.

摘要： 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.

摘要： An aerosol delivery apparatus is used to deliver an aerosol into a reaction chamber for chemical reaction to produce reaction products such as nanoparticles. A variety of improved aerosol delivery approaches provide for the production of more uniform reaction products. In preferred embodiments, a reaction chamber is used that has a cross section perpendicular to the flow of reactant having a dimension along a major axis greater than a dimension along a minor axis. The aerosol preferably is elongated along the major axis of the reaction chamber.
