  2. 1. Continuous Fibre Reinforced Oxide/Oxide Composites

    Author : Magnus Holmquist; Chalmers University of Technology; []
    Keywords : polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE

  5. 3. Aqueous Exfoliation of Transition Metal Oxides for Energy Storage and Photocatalysis Applications : Vanadium Oxide and Molybdenum Oxide Nanosheets

    Author : Ahmed S. Etman; Junliang Sun; Yury Gogotsi; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aqueous exfoliation; vanadium oxide nanosheets; molybdenum oxide nanosheets; energy storage; photocatalysis; Inorganic Chemistry; oorganisk kemi;

    Abstract : Two-dimensional (2D) transition metal oxides (TMOs) are a category of materials which have unique physical and chemical properties compared to their bulk counterparts. However, the synthesis of 2D TMOs commonly includes the use of environmental threats such as organic solvents. READ MORE

  6. 4. Screening of oxygen-carrier particles based on iron-, manganese-, copper- and nickel oxides for use in chemical-looping technologies

    Author : Marcus Johansson; Chalmers University of Technology; []
    Keywords : Oxygen Carrier; Carbon Dioxide Capture; Chemical-Looping Combustion; Chemical-Looping Reforming; Nickel Oxide; Iron Oxide; Copper Oxide; Manganese Oxide;

    Abstract : Capture and storage of carbon dioxide from combustion will likely be used in the future as a method of reducing emissions of greenhouse gases and thus be part of the overall strategy to stabilize the atmospheric levels of CO2. Chemical-looping combustion is a method of combustion where CO2 is inherently separated from the non-condensable components in the flue gas without the need for an energy intensive air separation unit.

  7. 5. Memory Effects on Iron Oxide Filled Carbon Nanotubes

    Author : Carlos Cava; Clas Persson; Lucimara Roman; Krister Svensson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Memory devices; Carbon Nanotubes; energy; nanotechnology; Iron Oxide;

    Abstract : In this Licentiate Thesis, the properties and effects of iron and iron oxide filled carbon nanotube (Fe-CNT) memories are investigated using experimental characterization and quantum physical theoretical models. Memory devices based on the simple assembly of Fe-CNTs between two metallic contacts are presented as a possible application involving the resistive switching phenomena of this material. READ MORE
