    摘要： Methods and apparatuses are provided for the production of homogeneous dispersions of nanostructures within a matrix, which may be used as precursors of carbon-reinforced or boron nitride-reinforced composite materials. An apparatus for producing a nanostructure dispersion comprises a reactor and a mixing chamber, wherein the reactor is configured to produce an aerosol of nanostructures and is in fluidic communication with the mixing chamber. A matrix material is provided in the mixing chamber, and the aerosol of nanostructures can disperse into the matrix material to form a nanostructure dispersion. The apparatus may further comprise a matrix tank comprising a matrix material, wherein the matrix material is transferred to the mixing chamber. An aerosol of matrix particles may be produced from the matrix material and provided in the mixing chamber, so as to produce a fine dispersion of nanostructures in the matrix. The apparatus may be configured to continuously produce a nanostructure dispersion.

    摘要： Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament between diverging surfaces. The stretched fluid filament breaks into droplets that can be harvested to form a mist or aerosol. The aerosol creation systems can include one or more pairs of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid. Some aerosol creation systems can include multiple pairs of counter-rotating rollers that are positioned in a circular, oval, or linear pattern. The aerosol creation system with multiple pairs of counter-rotating rollers can generate mist is one or more directions and can be positioned between two concentric rings or linearly, among other configurations.

    摘要： In one aspect, the present invention relates to a method of making multi-phase particles that include nanoparticulates and matrix, which maintains the nanoparticulates in a dispersed state. A flowing gas dispersion is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains liquid vehicle and at least a first precursor to a first material and a second precursor to a second material. The multi-phase particles are formed from the gas dispersion by removing at least a portion of the liquid vehicle from the droplets of precursor medium. The nanoparticulates in the multi-phase particles include the first material and the matrix in the multi-phase particles includes the second material.

    摘要： 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.
