  1. 16. Equilibrium studies of ternary aluminium(III) hydroxo complexes with ligands related to conditions in natural waters

    Författare :Lars-Olof Öhman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aqueous solution; binary and ternary hydroxo complexes of Al3 ; carbonic acid; citric acid; phenolic ligands; emf-titrations; equilibrium analysis; model calculations towards natural waters;

    Sammanfattning : The thesis is a summary and discussion of eight papers. During the last decades, precipitation has become increasingly acidic due to the extensive use of fossil fuels. In areas of poorly buffered bedrocks, e.g. LÄS MER

  3. 17. CO2 Separation - from Aqueous Amine Solvent to Ionic Liquid-based solvent

    Författare :Nan Wang; Xiaoyan Ji; James Glynn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : CO2 separation is one of the most important roles in CO2 mitigation target as many human production activities (e.g., cement, iron and steel, and biogas productions) cause CO2 emissions. The solvent-based absorption is the most mature technology for CO2 separation, where different solvents capture CO2 either in chemical or physical absorptions. LÄS MER

  4. 18. Development of low-cost ionic liquids based technology for CO2 separation

    Författare :Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : CO2 separation plays an important role to mitigate the CO2 emissions due to burning of fossil fuels, and it is also of importance in biofuel production (e.g. biogas upgrading and bio-syngas purification and conditioning). The solvent-based absorption is the state-of-art technology for CO2 separation, where various solvents, e. LÄS MER

  5. 19. Accident-tolerant uranium nitride

    Författare :Aneta Herman; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident-tolerant fuel; uranium nitride; chromium; glucose; internal sol-gel;

    Sammanfattning : After the nuclear accident at Fukushima-Daiichi in 2011, a search for alternatives to a current fuel-clad standard UO2-Zircaloy was encouraged by government and industry and novel fuel-clad systems were selected. These systems are often referred to as Accident Tolerant systems, because of an improved response to severe accidents. LÄS MER

  7. 20. Nonstoichiometric Multicomponent Nitride Thin Films

    Författare :Rui Shu; Per Eklund; Arnaud Le Febvrier; Jones Alami; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High entropy ceramics have rapidly developed as a class of materials based on high entropy alloys; the latter being materials that contain five or more elements in near-equal proportions. Their unconventional compositions and chemical structures hold promise for achieving unprecedented combinations of mechanical, electrical and chemical properties. LÄS MER
