  • Patent number: 9011710
    Abstract: Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.

  • Patent number: 8945410
    Abstract: Disclosed is a fuel cell with enhanced mass transfer characteristics in which a highly hydrophobic porous medium, which is prepared by forming a micro-nano dual structure in which nanometer-scale protrusions with a high aspect ratio are formed on the surface of a porous medium with a micrometer-scale roughness by plasma etching and then by depositing a hydrophobic thin film thereon, is used as a gas diffusion layer, thereby increasing hydrophobicity due to the micro-nano dual structure and the hydrophobic thin film. When this highly hydrophobic porous medium is used as a gas diffusion layer for a fuel cell, it is possible to reduce water flooding by efficiently discharging water produced by an electrochemical reaction of the fuel cell and to improve the performance of the fuel cell by facilitating the supply of reactant gases such as hydrogen and air (oxygen) to a membrane-electrode assembly (MEA).

    Abstract: The invention provides methods and kits for ordering sequence information derived from one or more target polynucleotides. In one aspect, one or more tiers or levels of fragmentation and aliquoting are generated, after which sequence information is obtained from fragments in a final level or tier. Each fragment in such final tier is from a particular aliquot, which, in turn, is from a particular aliquot of a prior tier, and so on. For every fragment of an aliquot in the final tier, the aliquots from which it was derived at every prior tier is known, or can be discerned. Thus, identical sequences from overlapping fragments from different aliquots can be distinguished and grouped as being derived from the same or different fragments from prior tiers. When the fragments in the final tier are sequenced, overlapping sequence regions of fragments in different aliquots are used to register the fragments so that non-overlapping regions are ordered.

  • Patent number: 8652362
    Abstract: The present invention provides a modified curing agent for a thermosetting resin, such as epoxy resin. As one example, the epoxy curing agent comprises: (a) multiple nano graphene platelets; (b) a chemical functional group having multiple ends with a first end being bonded to a nano graphene platelet and at least a second end reactive with the epoxy resin; and (c) reactive molecules acting as a primary cross-linking agent for the epoxy resin; wherein the nano graphene platelet content is no less than 0.01% by weight based on the total weight of the modified curing agent. A modified curing agent containing reactive molecule-functionalized NGPs enable excellent dispersion of NGP in a resin matrix and the resulting nanocomposites exhibit much better properties than those of corresponding nanocomposites prepared by directly mixing dried NGPs with the thermosetting resins.

    Abstract: A silica-based nanoformulation and method is used to treat citrus canker, inhibit the growth of mold and mildew, and add nutrients to soil used for agricultural purposes. The nanotechnology-enabled copper-loaded, silica nanoformulation (CuSiNP/NG) design is a “revolutionary re-invention” of Cu for safe application because it provides a formulation with maximum abundance of ionic Cu, provides sustained and optimal Cu ion release for long-term disease protection, better adherence to plant surfaces and structural surfaces due to gel-based nanostructure of CuSiNG, thus avoiding multiple spray applications and reducing the amount of Cu used in comparison to existing Cu compounds without compromising antibacterial activity.

  • Patent number: 8623237
    Abstract: The present invention describes a composition and a method for producing mesoporous silica materials with a chiral organization. In the method, a polymerizable inorganic monomer is reacted in the presence of nanocrystalline cellulose (NCC) to give a material of inorganic solid with cellulose nanocrystallites embedded in a chiral nematic organization. The NCC can be removed to give a stable porous structure that retains the chiral organization of the NCC template. The new materials may be obtained as iridescent free-standing films with high surface area. Through control of the reaction conditions, the color of the films can be varied across the entire visible spectrum. These are the first materials to combine mesoporosity with long-range chiral ordering that leads to photonic properties.
