  • Patent number: 7919562
    Abstract: The present invention relates to supramolecular polymers containing sequence-selective hydrogen bonding subunits in their backbone which form double helices. The invention allows for tuning of the numbers and sequences of donor/acceptor units incorporated in any one crosslinking hydrogen bonding subunit and hence tuning of the interaction strength not only through the amount of crosslinking material incorporated but also through modulation of the strength of the crosslinking interactions. It also allows for the incorporation of more than one type of crosslinking agent in the material allowing for multiple strengths of crosslinking which are each tunable with regard to disruption from solvent, temperature and stress. Hydrogen bond strength between oligomeric chains can be tailored through modification of the numbers and sequences of the donors/acceptors in the oligomers.

  • Publication number: 20110041912
    Abstract: The present invention provides phosphonium ionic liquids (11) and coatings made therefrom. Highly fluorinated phosphonium ionic liquids based on (11) having been produced exhibiting high thermal stabilities, low melting points and temperature dependent solvent miscibilities. These salts and derivatives of (11) have also been employed in the preparation of superhydrophobic surfaces, indicating that ionic liquids are not only new alternative solvents, but also viable functional materials. All derivatives of (11) form biphasic systems with common laboratory solvents of ranging polarity at room temperature. Based on the solvent miscibility experiments with water and the high fluorine loading, the PILs showed obvious evidence of being hydrophobic. Coatings made with these phosphonium ionic liquids (11), salts and derivatives thereof were superhydrophobic with water contact angles were measured and all of the surfaces were determined to be superhydrophobic with contact angles >150°.

  • Patent number: 7878430
    Abstract: Blending methods for adding and uniformly mixing a small fraction of relatively small particles (additives) to a bulk particulate powder of larger size than the additives. In particular, the present invention provides blending methods for adding and uniformly mixing a small percentage of flow/fluidization additives into fine powders, especially fine paint powders. The fine powder and additives are first pre-mixed for macro-scale homogeneity and then further mixed at a micro-scale (such as with a screen mixing process) for micro-scale homogeneity. With these methods, optimum dispersions and maximum functionalities of additives can be obtained and the disadvantages caused by severe agglomerates of additives can be avoided.

  • Patent number: 7844113
    Abstract: A region-based push-relabel formulation is disclosed that removes the requirement that the entire graph should fit into the computer memory and yields an implementation that can reduce the required size and redundancy of accesses to the data memory, thus improving speed performance, while allowing for an efficient parallel processing implementation. The algorithm assigns all vertices that are not part of the sources or sinks with a value of 1. Sinks are assigned with zeros and sources are assigned a label equal to the number of their vertices. The preflow is then pushed from the sources to their neighbors, if any. When the preflow has all reached the boundaries, an adjacent region of the neighboring set is selected and preflow is pushed within this region. When the values of the preflow have been exhausted, region relabeling is done to update the label values. This is repeated within the region until all preflow has exited to the boundary of this region.

  • Patent number: 7736513
    Abstract: Biological nutrient removal (BNR) in wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations. Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological nutrient removal in a twin liquid-solid fluidized bed, which has achieved the simultaneous elimination of organic carbon, nitrogen and phosphorus, in a very efficient manner and with very compact space requirements. The BNR-LSFB has two fluidized beds, running as anoxic/anaerobic and aerobic processes to accomplish simultaneous nitrification and denitrification and to remove carbonaceous substrates, nutrients and phosphorus, with continuous liquid and solids recirculation through the anoxic/anaerobic bed and the aerobic bed.

  • Publication number: 20100130351
    Abstract: Rare earth element(s) doped alumina nanowires are formed by a thermal evaporation method in which vapor from aluminum powder and vapor from a rare earth element compound (such as an halide) are reacted in an oxygen-containing inert gas stream to form alumina which deposits as alumina nanowires and as a rare earth element and oxygen-containing material that deposits with and/or on the alumina nanowires. Where the RE-doped alumina nanowires are to be used as catalyst supports, a catalyst material, such as platinum, may be deposited as small particles on the nanowires.

  • Patent number: 7687161
    Abstract: The present invention discloses a method of generating electricity which uses a new type of biofuel cell. The method is based on the microbial regeneration of the oxidant, ferric ions. The bio-fuel cell is based on the cathodic reduction of ferric to ferrous ions, coupled with the microbial regeneration of ferric ions by the oxidation of ferrous ions, with fuel (such as hydrogen) oxidation on the anode. The microbial regeneration of ferric ions is achieved by chemolithotrophic microorganisms such as Acidithiobacillus ferroxidans. Electrical generation is coupled with the consumption of carbon dioxide from atmosphere and its transformation into microbial cells, which can be used as a single-cell protein.

  • Publication number: 20100028364
    Abstract: A method of treating a pathophysiological condition caused by the production of growth-inhibiting proteoglycans is provided. It is based on the finding that down-regulation of SOX9 results in decreased production of growth-inhibiting factors such as proteoglycans, and increased production of growth-promoting factors such as a laminin and fibronectin. The method of the present invention comprises the inhibition of SOX9 expression and function with an inhibitor such as an antisense oligonucleotide or a siRNA.
