  • Patent number: 9155595
    Abstract: The present invention provides a selective coating of an endodontic file, in which the distal end of the file is uncoated or alternatively leaving the outermost part of the blades of the distal end portion uncoated. The distribution of the nanoparticles is thus non uniform along the surface of the file leaving only a part of the file coated. In the present invention, the distal end of the device being subjected to the highest torque is either uncoated at all, or has a coated core and uncoated blades.

  • Patent number: 7959891
    Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber towards a reaction zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core exhibiting excellent tribological behaviour. The present invention further provides an apparatus for preparing various IF nanostructures.

  • Patent number: 7641869
    Abstract: A process and apparatus are presented for obtaining inorganic fullerene-like nanostructures. A metal oxide is evaporated at predetermined temperature conditions, and is swept towards a reacting zone, to which first and second gas phase reacting agents are concurrently swept. The evaporated metal oxide thus interacts with the first reacting agent and is converted into metal suboxide nanoparticles in the gas phase. The condensing metal suboxide nanoparticles interact with the second reacting agent in the gas phase resulting in substantially pure phase of the inorganic fullerene-like nanoparticles.
