  2. 1. Cobalt and Nickel Bioavailability for Biogas Formation

    Author : Jenny Gustavsson; Bo Svensson; Anna Karlsson; Piet N.L. Lens; Linköpings universitet; []
    Keywords : Biogas production; bioavailability; cobalt; nickel; sequential extraction; S XANES; 454-pyrosequencing.; Biogasproduktion; biotillgänglighet; kobolt; nickel; sekventiell extraktion; S XANES; 454-pyrosekvensering;

    Abstract : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. READ MORE

  4. 2. In vitro analyses of immune responses to metal and organic haptens in humans with contact allergy

    Author : Khosro Masjedi; Marita Troye-Blomberg; Niklas Ahlborg; Lone Skov; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ELISpot; contact allergy; parthenolide; methylisothiazolinones; nickel; hapten; Allergology; Allergologi; immunologi; Immunology;

    Abstract : Contact allergy is one of the most common skin diseases with great social and economical impact. The origin and nature of contact allergens (haptens) capable of inducing T-cell mediated allergic reactions are diverse, ranging from organic molecules to metal ions. READ MORE

  5. 3. The anode and the electrolyte in the MCFC

    Author : Andreas Bodén; Göran Lindbergh; Carina Lagergren; Takao Watanabe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite electrolytes; electrode kinetics; nickel solubility; porous electrode; reformate; water-gas shift reaction; electrolyte; electrolyte distribution; hydrogen oxidation reaction; ion segregation; mass transport; mathematical modelling; MCFC; molten carbonate fuel cell; Chemical engineering; Kemiteknik;

    Abstract : A goal of the Swedish government is to increase the usage of renewable fuels and biomass-based fuels. Fuel cells, and especially the MCFC, are useful for these types of fuels. The Swedish market may benefit from the MCFC in two ways: increased efficiency of the biofuels and also utilisation of produced heat in district heating. READ MORE

  6. 4. Characterisation of materials for use in the molten carbonate fuel cell

    Author : Sara Randström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molten Carbonate Fuel Cell; Anode Current Collector; Cathode; Wet-seal; Chemical engineering; Kemiteknik;

    Abstract : Fuel cells are promising candidates for converting chemical energy into electrical energy. The Molten Carbonate Fuel Cell (MCFC) is a high temperature fuel cell that produces electrical energy from a variety of fuels containing hydrogen, hydrocarbons and carbon monoxide. READ MORE

  7. 5. Crystallization of Metal Fluoride Hydrates from Mixed Acid Solutions

    Author : Kerstin Forsberg; Åke Rasmuson; Alison Lewis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crystallization; crystal growth; b-FeF3.3H2O; iron fluoride trihydrate; CrF3.3H2O; pickling; pickle bath; hydrofluoric acid; nitric acid; stainless steel; Chemical engineering; Kemiteknik;

    Abstract : In this work crystal growth and nucleation of b-FeF3×3H2O and crystallization of chromium (III), iron (III) and nickel (II) fluoride hydrates from mixed acid (1-3 mol/kg HNO3 and 1-6 mol/kg free HF) have been investigated. The solubility of b-FeF3×3H2O has been determined in solutions of different hydrofluoric acid (1-7mol/ kg) and nitric acid (0-7mol/ kg) concentrations at 30, 40 and 50°C. READ MORE
