  1. 1. Nitric oxide : An ally in extracorporeal circulation?

    Författare :Vilyam Melki; Jan Borowiec; Örjan Friberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Simulated extracorporeal circulation; Inflammation; Nitric oxide; Leukocyte activation; Staphylococcus aureus; Glyceryl trinitrate; Postoperative infection; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Many complications associated with heart surgery are due to the negative effects of extracorporeal circulation (ECC). Some of these complications may be attributed to ECC-induced activation of inflammation and coagulation pathways. LÄS MER

  3. 2. Continuous Fibre Reinforced Oxide/Oxide Composites

    Författare :Magnus Holmquist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. The Buried Oxide of Silicon on Insulator Materials

    Författare :Per Ericsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide defects; internal oxidation; aluminum oxide; wafer bonding; SOI; silicon on insulator; buried oxide;

    Sammanfattning : The buried oxide of silicon on insulator (SOI) wafers plays an important role in the operation of electronic devices made on such materials. The presence of defects in the buried oxide can seriously degrade the performance of a circuit. LÄS MER

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

    Författare :Marcus Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Oxygen Carrier; Carbon Dioxide Capture; Chemical-Looping Combustion; Chemical-Looping Reforming; Nickel Oxide; Iron Oxide; Copper Oxide; Manganese Oxide;

    Sammanfattning : 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.
