  2. 1. Thin Film Synthesis of Nickel Containing Compounds

    Author : Erik Lindahl; Jan-Otto Carlsson; Jens Birch; Uppsala universitet; []
    Keywords : 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.

  4. 2. Investigation of Nickel- and Iron-Based Oxygen Carriers for Chemical-Looping Combustion

    Author : Erik Jerndal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Capture; Nickel Oxide; Fluidized Bed; Iron Oxide; Oxygen Carrier; Chemical-Looping Combustion; Ilmenite;

    Abstract : Carbon capture and storage has the potential of reducing emissions of CO2, generated by combustion of fossil fuels. Chemical-looping combustion is a method intended to capture CO2 without an energy consuming gas separation process. READ MORE

  5. 3. Electrochromism in Nickel-based Oxides : Coloration Mechanisms and Optimization of Sputter-deposited Thin Films

    Author : Esteban Damián Avendaño Soto; Gunnar Niklasson; Andris Azens; Claes-Göran Granqvist; Ulf Helmersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Nickel based Oxide; Electrochromism; Thin Films; Sputtering; Coloration mechanism; Fysik; Physics; Fysik;

    Abstract : Electrochromic properties of sputter-deposited nickel-based oxide films have been studied with a two-fold goal. From a practical point of view, the optical switching performance has been improved by optimizing the deposition conditions and film stoichiometry with respect to oxygen and hydrogen, and further by adding Mg, Al, Si, Zr, Nb or Ta to the films.

  6. 4. Chemical-Looping Combustion with Natural Gas Using NiO-Based Oxygen Carriers

    Author : Carl Johan Linderholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion; fluidized bed; CO2 capture; nickel oxide; oxygen carrier;

    Abstract : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier and the CO2 capture is inherently achieved. READ MORE

  7. 5. Thermal Analysis and Investigation of NiO-Based Oxygen Carriers for Chemical-Looping Combustion

    Author : Erik Jerndal; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxygen Carrier; Carbon Dioxide Capture; Chemical-Looping Combustion; Nickel Oxide; Fluidized Bed; Thermodynamics;

    Abstract : Capture and storage of CO2 can be used to reduce greenhouse gas emissions from combustion of fossil fuels. Chemical-looping combustion is a two-step combustion process where CO2 is obtained in a separate stream, ready for compression and storage. READ MORE
