    Abstract: Disclosed is a composite of enzyme and carbon structure. In the composite of enzyme and carbon structure, a significantly large amount of an enzymeis immobilized on the surface of carbon structures without the formation of chemical bonds (particularly, covalent bonds) between the enzyme molecules and the carbon structures. Since the surface of the carbon structures does not need to be modified to form chemical bonds, the electrical conductivity of the composite of enzyme and carbon structure is not reduced and the stability of the composite is maintained high even after the passage of a long time in various environments. Therefore, the use of the composite of enzyme and carbon structure enables the fabrication of various devices, such as biosensors and biofuel cells, with markedly improved performance as compared to the use of conventional enzyme/carbon structure composites.

  • 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.

  • Publication number: 20140096682
    Abstract: Methods and apparatus relate to recovery of carbon dioxide and/or hydrogen sulfide from a gas mixture. Separating of the carbon dioxide, for example, from the gas mixture utilizes a liquid sorbent for the carbon dioxide. The liquid sorbent contacts the gas mixture for transfer of the carbon dioxide from the gas mixture to the liquid sorbent. Contacting of the sorbent with the gas mixture and/or desorption of the carbon dioxide from the liquid sorbent utilize hollow fiber contactors that have permeable walls and incorporate particles distinct from a remainder of the walls to influence wetting properties of the contactors. Polytetrafluoroethylene particles may be homogenously disposed throughout hollow fiber contactors to influence wetting properties of the contactors.

  • Patent number: 8691324
    Abstract: Disclosed herein are solvent free, dry coating processes for applying a layered material such as graphene, nanoplate graphite, etc., to a substrate. The applied layered material is devoid of any dispersant and substantially uniform in thickness. Generally, a layered material precursor composition is mixed with a milling medium so that the milling medium is coated with the layered material. The substrate is then contacted with the coated milling medium. The layered material on the milling medium transfers to the substrate to form a coating on the substrate. Such processes may be especially useful for applying conductive films onto a polymeric substrate without the need for additives such as a surfactant or a polymeric binder.

  • Publication number: 20140004262
    Abstract: The present disclosure relates to apparatus designed to impregnate a sorbent. In some embodiments apparatus of the disclosure may comprise a mixing vessel having either a conical mixing chamber or an cylindrical mixing chamber designed to increase the contact surface area and/or contact/residence time of a sorbent and impregnant to produce compositions comprising an impregnated sorbent. Apparatus of the disclosure may also comprise one or more atomizers operable to produce atomized droplets of impregnant. The disclosure also provides methods for impregnation of a milled sorbent or an un-milled sorbent. Methods of the disclosure provide several technical advantages and may be cost effective. Impregnant sorbent compositions produced by methods and/or apparatus of the disclosure may have higher concentrations of an impregnant, a more uniform distribution of an impregnant and may have a greater sorbent efficiency.

  • Patent number: 8574669
    Abstract: A fine polymer particle production method includes producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.
