  • Patent number: 9205590
    Abstract: Polymer pellets are formed using air to influence the separation of polymer from a polymer melt. In accordance with one or more embodiments, a polymer material is extruded through a nozzle to form a polymer melt extending from the nozzle. A non-uniform thickness is generated in the polymer melt using a gas or gasses to apply a drag force to the polymer melt. This drag force reduces a thickness of a portion of the polymer melt adjacent the nozzle, and the polymer melt is fractured into discrete droplets at the reduced thickness. The discrete droplets are then solidified to form pellets.

    Abstract: Nanofibers are fabricated by introducing a mixture of a polymer solution and inorganic precursor into a dispersion medium and shearing the mixture. Liquid strands, streaks or droplets of the mixture are spun into elongated fibers that include inorganic fibrils. The resulting composite inorganic/polymer fibers may be provided as an end product. Alternatively, the polymer may be removed to liberate the inorganic fibrils, which may be of the same or smaller cross-section as the polymer fibers and may be provided as an end product.

  • Publication number: 20120187591
    Abstract: The present invention provides for methods of preparing silk nanoparticles and microparticles, methods of encapsulating an active agent into the silk nano- and microparticles and compositions comprising these silk particles. In particular, the silk spheres are prepared from phase separation of silk and polyvinyl alcohol (PVA), without exposure to an organic solvent. The method employs a chemical, PVA, which is an FDA-approved ingredient in drug formulations. Different parameters can be adjusted to control the size and shape of the silk spheres during the fabrication process. The silk particle compositions of the present invention may also encapsulate active agents or chemicals. Such compositions allow the active agents to be controllably and sustainably released to the target organs or tissues. The silk composition entrapping active agents also provides for a long-term storage medium for the active agents so entrapped.

    Abstract: A composite nanoparticle, for example a nanoparticle containing one or a plurality of cores embedded in another material. A composite nanoparticle can be formed by a one step process that includes: ejecting material from a bulk target material using physical energy source, with the bulk target material disposed in a liquid. Composite nanoparticles are formed by cooling at least a portion of the ejected material in the liquid. The composite fine particles may then be collected from the liquid. A product that includes composite fine particles may be formed with laser ablation, and ultrashort laser ablation may be utilized so as to preserve composite nanoparticle stoichiometry. For applications of the composite fine particles, optical properties and/or magnetic properties may be exploited for various applications.
