    Abstract: Polishing compositions are described that are appropriate for fine polishing to very low tolerances. The polishing compositions include particles with small diameters with very narrow distributions in size and effectively no particles with diameters several times larger than the average diameter. Furthermore, the particles generally have very high uniformity with respect to having a single crystalline phase. Preferred particles have an average diameter less than about 200 nm. Laser pyrolysis processes are described for the production of the appropriate particles including metal oxides, metal carbides, metal sulfides, SiO2 and SiC.

    Abstract: 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.

    Abstract: A method for efficiently producing particles from gas phase chemical reactions induced by a radiation beam. The apparatus includes a reaction chamber and an elongated reactant inlet, where the reaction chamber is configured to conform generally to the elongated shape of the reactant inlet. Shielding gas may be introduced to form a blanket of inert gas on both sides of the reactant stream. A feed back loop may be used to maintain the desired pressure within the reaction chamber.

    Abstract: Electromagnetic shielding material is formed from a shielding composition made with magnetic particles and a binder, where the magnetic particles have an average diameter less than about 1000 nm and are substantially crystalline. The magnetic particles can be formed from Fe.sub.2 O.sub.3, Fe.sub.3 O.sub.4, Fe.sub.3 C, or Fe.sub.7 C.sub.3. The shielding composition can be formed into a layer or into composite particles. The binder can be a metal or an electrically conducting polymer. A conducting layer can be placed adjacent to the shielding composition. The shielding material can be used to protect sensitive electronic devices. Methods are described for forming iron oxide particles by laser pyrolysis.
