20140087058 | METHOD FOR PRODUCING ENCAPSULATED NANOPARTICLES - A method is provided that produces nanocomposite materials containing well-dispersed, nanoparticles encapsulated in a polymer matrix. A feedstock comprising a colloidal dispersion of nanoparticles in a solvent and a polymer dissolved in the same solvent is passed through an ultrasonic nozzle using a flow control device, producing an aerosol of drops having diameters less than about 100 micrometers. The aerosol of drops is then mixed with a fluid that is miscible with the solvent, is a nonsolvent for the polymer, and destabilizes the colloidal dispersion. As a result, well-dispersed polymer-encapsulated nanoparticles precipitate. The method operates at atmospheric temperature and pressure and allows for independent control of the precipitation of the particle and of the polymer. | 03-27-2014 |
20140336295 | POROUS BODY USEFUL AS A FILTER ELEMENT - A porous body consists essentially of a plurality of ceramic particles having an average size ranging from 8 to 100 nm. The ceramic particles are bonded to adjacent ceramic particles with a strength sufficient to render the porous body self-supporting. The porosity ranges from 30 to 70 vol. % and the average pore size ranges from 5 to 50 nm. The porous body may be manufactured by preparing a dispersion comprising the ceramic particles and a polymer matrix material in a solvent, removing the solvent by heating and/or evaporation, forming a preform of the dried material, and firing the preform to remove the polymer matrix material and bond the ceramic particles to each other. The porous body is useful as a filter element in a system adapted to remove nanoscale particles from a fluid stream. | 11-13-2014 |
