  • Patent number: 8475627
    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.

    Abstract: Methods of forming liquid hydrocarbons through thermal deoxygenation of cellulosic compounds are disclosed. Aspects cover methods including the steps of mixing a levulinic acid salt-containing feedstock with a formic acid salt, exposing the mixture to a high temperature condition to form hydrocarbon vapor, and condensing the hydrocarbon vapor to form liquid hydrocarbons, where both the formic acid salt and the levulinic acid salt-containing feedstock decompose at the high temperature condition and wherein one or more of the mixing, exposing, and condensing steps is carried out a pressure between about vacuum and about 10 bar. Other methods and parameters for generating energy dense liquid hydrocarbons are also disclosed and claimed.

  • Patent number: 8197732
    Abstract: The present invention resides in one aspect in a building material that comprises wood and a composite polymeric material that is combined with the wood in a heterogenous admixture. The composite polymeric material incorporates fibers in a polymeric matrix. The fibers can be chopped, continuous, or combinations thereof. In addition, the fibers can be unidirectionally oriented and/or randomly oriented. Suitable fibers for use in the composite polymeric material are glass, polymers, carbon, combinations thereof, and the like. However, the present invention is not limited in this regard as other fibers known to those skilled in the pertinent art to which the invention pertains can be used without departing from the broader aspects of the present invention. Suitable polymeric material for the polymeric matrix include thermoplastic polymers, thermosetting polymers, or a combination of thermosetting and thermoplastic polymers.

  • Publication number: 20120135446
    Abstract: A combinatorial microenvironment generator is configured for the generation of arbitrary, user-defined, steady-state, concentration gradients with negligible to no flow through the growth medium to perturb diffusion gradients or cellular growth. More importantly, the absolute concentrations and/or gradients can be dynamically altered upon request both spatially and temporally to impose tailored concentration fields for in-situ stimulus studies. Here, diffusion occurs via an array of ports, each of which can be an independently controlled source/sink. Together, the array of ports establishes a user-defined, 3D concentration profile. Useful methods related to this device are also provided.

  • Publication number: 20120018651
    Abstract: A Polarization Fluorescence Photoactivation Localization Microscopy (P-FPALM) system and method are provided to simultaneously image the localizations and fluorescence anisotropics of large numbers of single molecules within a sample. The system modifies known FPALM systems by adding a polarizing beam splitter. The beam splitter polarizes emissions perpendicular and parallel to an axis in the sample to allow spatially separate imaging of fluorescence emitted from a sample. The system includes lenses and mirrors so that the separate, polarized beams are detected simultaneously. The present invention includes methods of using the system to image localizations and fluorescence anisotropics of single molecules, and methods of using data obtained with the system to predict 3-D orientation of the molecules. The system and method achieve substantially improved lateral resolution within even dense samples over known microscopic imaging techniques, and does not compromise speed or sensitivity.
