  • Publication number: 20110260348
    Abstract: A method of producing dried cellulose nanofibrils includes atomizing an aqueous suspension of cellulose nanofibrils and introducing the atomized aqueous suspension into a drying chamber of a drying apparatus. The aqueous suspension is then dried, thereby forming substantially non-agglomerated dried cellulose nanofibrils.

  • Patent number: 8043384
    Abstract: A method for making fire retardant material including fire retardant cellulosic insulation is described. The method includes an arrangement for adding one or more feedstocks and a fire retardancy chemical compound to a common blend tank prior to feedstock drying. The one or more feedstocks may include at least one virgin pulp stock feed and at least one recycled material stock feed. The amount and type of both the virgin feedstock and the recycled material feedstock is selectable. Old newsprint (ONP) may be one type of recycled material feedstock. Another suitable type of recycled material feedstock is old corrugated containers (OCC). The method further includes retaining the fiber feedstock and the chemical compound together for enough time to ensure adherence or impregnations of enough of the chemical to the fibers after the drying process. Fluffing or fiberizing of the treated fibers may be accomplished under less severe conditions than ordinarily employed when making conventional cellulose insulation.

  • Publication number: 20110214826
    Abstract: A process of treating a lignocellulosic material includes a pre-extraction step in which hemicellulose is extracted from the lignocellulosic material. In one embodiment, the pre-extraction step involves contacting the lignocellulosic material with an aqueous solution under conditions that release acidic material from the lignocellulosic material into the aqueous solution, and the aqueous solution includes a basic material that at least partly neutralizes the acidic material so that the aqueous solution at the end of the pre-extraction step has a pH within a range of from 4.5 to 11. The process also includes a pulping step, after the pre-extraction step, in which the lignocellulosic material is separated into pulp. The process further includes an adsorption step, after the pulping step, in which hemicellulose is adsorbed on the pulp.

  • Publication number: 20110091711
    Abstract: Methods and apparatuses for forming carbon nanostructures from a polymer mixture. The methods include the steps of mixing the pre-formed polymer with a liquid to form a polymer mixture, freezing the polymer mixture at an effective freezing rate greater than or equal to 103 Kelvin per second to form a polymer cast within the frozen liquid, separating the polymer cast from the frozen liquid by sublimating the frozen liquid, and carbonizing the polymer cast to form a carbon nanostructure. Variations of these methods are included in the scope of the invention and produce materials with varying properties. Through control of the freezing process, the nanomorphology of the resultant structure may be modulated. Nanostructures formed according to these methods are also claimed.

  • Publication number: 20110030089
    Abstract: The invention relates to transgenic plants exhibiting dramatically enhanced growth rates, greater seed and fruit/pod yields, earlier and more productive flowering, more efficient nitrogen utilization, increased tolerance to high salt conditions, and increased biomass yields. In one embodiment, transgenic plants engineered to over-express both glutamine phenylpyruvate transaminase (GPT) and glutamine synthetase (GS) are provided. The GPT+GS double-transgenic plants of the invention consistently exhibit enhanced growth characteristics, with T0 generation lines showing an increase in biomass over wild type counterparts of between 50% and 300%. Generations that result from sexual crosses and/or selfing typically perform even better, with some of the double-transgenic plants achieving an astounding four-fold biomass increase over wild type plants.

  • Patent number: 7862675
    Abstract: A method for manufacturing a reinforced beam having a bonded tensile reinforcement member includes assembling a tensile reinforcement member to a beam, wherein adhesive is disposed between the tensile reinforcement member and the beam. A load is applied to the tensile reinforcement member to define a pre-tensioned tensile reinforcement member. A force is applied to urge the beam and the pre-tensioned tensile reinforcement member together. The load is released on the pre-tensioned tensile reinforcement member prior to the adhesive becoming cured, allowing longitudinal ends of the tensile reinforcement member to slide relative to the beam at longitudinal ends of the beam, and thereby forming a reinforced beam having a bonded tensile reinforcement member.
