  • Publication number: 20170001865
    Abstract: The present invention relates to covalently bonded fullerene-functionalized carbon nanotubes(CBFFCNTs), a method and an apparatus for their production and to their end products. CBFFCNTs are carbon nanotubes with one or more fullerenes or fullerene based molecules covalently bonded to the nanotube surface. They are obtained by bringing one or more catalyst particles, carbon sources and reagents together in a reactor.

  • Patent number: 9133022
    Abstract: A structure comprising high aspect ratio molecular structures (HARM-structures), wherein the structure comprises an essentially planar network (2) of HARM-structures, and a support (3) in contact with the network (2). The support (3) has an opening (5) therein, at the peripheral region (4) of which opening (5) the network (2) is in contact with the support (3), such that the middle part of the network (2) is unsupported by the support (3). The network (2) comprises essentially randomly oriented HARM-structures.

  • Patent number: 9023165
    Abstract: A method for the production of a fibrous network-substrate component includes the steps of providing a network of fibrous material (1) on a preliminary substrate (2) by filtering high aspect ratio molecular structures (HARM-structures) from gas flow, placing the network of fibrous material (1) on the preliminary substrate (2) in proximity to a secondary substrate (3), applying a force to the network of fibrous material (1) to preferably attract the network of fibrous material (1) from the preliminary substrate (2) to the secondary substrate (3) in order to transfer the network of fibrous material (1) from the preliminary substrate (2) to the secondary substrate (3), and removing the preliminary substrate (2) from the network of fibrous material (1).

  • Patent number: 8349295
    Abstract: A method and apparatus for multicomponent surface modified aerosol particle production suitable for, for instance, therapeutic, cosmetic or diagnostic use in which an aerosol containing an active agent is introduced in an aerosol reactor together with a surface agent or surface agent source and/or precursor and wherein the surface agent and/or surface agent precursor is volatilizable. The surface agent vapor saturation ratio is elevated so to cause it to nucleate from the gas phase. Reactor conditions are maintaining such that the active agent remains in the condensed phase and provides a surface for the surface agent to deposit on the active agent containing aerosol particle thus producing surface modified aerosol particles. The method can be used for batch or continuous production. Particles made according to the method and powders and dispersions containing the particles are also described.
