  2. 21. The Chemistry of Plutonium Solubility

    Author : Hans Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sorption; colloids; solubility; modeling; oxidation states; plutonium; hydrolysis; actinides;

    Abstract : When designing a repository for spent nuclear fuel it is necessary to assess the possibility that radionuclides will be transported from the repository by groundwater. A limiting factor for such transport is the solubility of any given radionuclide. READ MORE

  4. 22. Galactoglucomannan-degrading enzymes from Aspergillus niger

    Author : Pia Ademark; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Aspergillus niger; beta-mannosidase; alpha-galactosidase; purification; hydrolysis; cloning; galactoglucomannan; expression; Biochemistry; Metabolism; Biokemi;

    Abstract : Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their degradation, i.e., endo-1,4-beta-mannanase (beta-mannanase, EC 3. READ MORE

  5. 23. Integrated starch and lignocellulose based biorefineries : Synergies and opportunities

    Author : Michael Persson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process integration; Fermentation; Hydrolysis; Lignocellulosic Biomass; Wheat grain; Bioethanol;

    Abstract : The transition from a reliance on fossil resources to the use of renewables for the production of energy, fuels and chemicals is essential for ensuring the sustainability of continued human development. Plant-based biomass is a renewable resource which can be transformed into all of these products. READ MORE

  6. 24. The Use of Aliquat-336 in a Partitioning and Transmutation Process and a Kinetic Study of the Oxidation of U(IV) to U(VI)

    Author : Anders Landgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; partitioning; quaternary ammonium salts; transmutation; hydrolysis; Aliquat-336; liquid-liquid extraction; kinetics; oxidation; uranium IV ;

    Abstract : Spent nuclear fuel contains several long-lived radionuclides that must be stored in a safe manner for a long time. Transmutation of these radionuclides into short-lived or stable nuclides reduces the necessary storage time by several orders of magnitude. The nuclides most suitable for transmutation are those of the actinides. READ MORE

  7. 25. Emulsification of Alkyl Ketene Dimer (AKD) -characterization of dispersions and emulsifiers

    Author : Kristina Mohlin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrolysis; droplet size; hydrophobizing agent; dispersion; surfactant; AKD; emulsification; viscosity; surface tension; polymer; phase behavior; Alkyl Ketene Dimer;

    Abstract : Alkyl Ketene Dimer (AKD) is a commonly used hydrophobizing agent in the paper industry, introducing capillary absorption barriers for polar liquids, which makes the paper more resistant to liquid penetration. Since AKD is a so-called internal sizing agent it is usually added in the form of a water-borne dispersion. READ MORE
