  2. 2. Thin Film Synthesis of Nickel Containing Compounds

    Author : Erik Lindahl; Jan-Otto Carlsson; Jens Birch; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chemical Vapor Deposition; CVD; Atomic Layer Deposition; ALD; Nickel nitride; Nickel oxide; Nickel; Epitaxy; multilayer; Thin film; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : Most electrical, magnetic or optical devices are today based on several, usually extremely thin layers of different materials.  In this thesis chemical synthesis processes have been developed for growth of less stable and metastable layers, and even multilayers, of nickel containing compounds.

    Abstract : Kliniska och experimentella studier av nickelallergi Nickelallergi är vanligt, särskilt hos kvinnor. Nickelallergi leder ofta till periodiskt eller kroniskt eksem, främst på händerna. Dessa eksem kan vara svårläkta och leda till långa sjukskrivningsperioder. READ MORE

  4. 4. Chemical Speciation of Sulfur and Metals in Biogas Reactors : Implications for Cobalt and Nickel Bio-uptake Processes

    Author : Sepehr Shakeri Yekta; Bo Svensson; Ulf Skyllberg; Åsa Danielsson; Charles Banks; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; NATURAL SCIENCES; Biogas; Anaerobic digestion; Chemical speciation; bio-uptake; Sulfur; Iron; Cobalt; Nickel; Biogas; Anaerob nedbrytning; Kemisk speciering; Bio-upptag; Svavel; Järn; Kobolt; Nickel;

    Abstract : A balanced supply of micronutrients, including metals such as iron (Fe), cobalt (Co), and nickel (Ni), is required for the efficient and stable production of biogas. During biogas formation, the uptake of micronutrient metals by microorganisms is controlled by a complex network of biological and chemical reactions, in which reduced sulfur (S) compounds play a central role.

  5. 5. Process development for platform chemical production from agricultural and forestry residues

    Author : David Nickel; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; multi-scale variability analysis; logging residues; ethanol; lactic acid; preadaptation; pretreatment; lignocellulose; Biorefinery; platform chemicals; multi-feed SSCF; mixed feedstocks;

    Abstract : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. READ MORE
