  2. 1. Structural and Magnetic Properties of Fe/Co (001) and Fe/V (001) Superlattices

    Author : Peter Blomqvist; Jens Birch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Tunna filmer; kristallin struktur; magnetism; järn; kobolt; vanadin; Physics; Fysik; fysik; Physics;

    Abstract : The structural and magnetic properties of Fe/Co (001) and Fe/V (001) superlattices have been investigated. The thin film structures were deposited on MgO (001) substrates using a four source ultra-high-vacuum based sputtering equipment. READ MORE

  4. 2. A Study on Vanadium Extraction from Fe-V-P Melts Derived from Primary and Secondary Sources

    Author : Mikael Lindvall; Du Sichen; Christiaan Pistorius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vanadium; V; V2O5; V2O3; ferrovanadium; vanadiferous; titaniferous; titanomagnetites; magnetite; spinel; slag; experimental; free; spinel; converter; LD; BOF; solubility; equilibrium; selective; oxidation; hibonite; karelianite; Al2O3; CaO; SiO2; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Vanadium extraction methods were developed for iron-vanadium-phosphorus (Fe-V-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. READ MORE

  5. 3. A study of an autogenous slag for steel production with consideration of possible vanadium extraction

    Author : Amanda Vickerfält; Pär Jönsson; Du Sichen; Johan Martinsson; Takahiro Miki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The thesis discusses the use of the autogenous slag that forms from the residual oxides present in hydrogen reduced iron (H-DRI) pellets during melting. The studies are motivated by a better understanding of how H-DRI affect the steelmaking operations. READ MORE

  6. 4. A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions

    Author : Roland Nilsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; oxidation; Ammoxidation; propane; propene; propylene; catalysis; transient response; antimony vanadium oxides;

    Abstract : Propane ammoxidation catalysts of differing Sb/V ratio and consisting of differing amounts of the V2O5, alpha-Sb2O4, and Sb0.92V0.92O4 phases were prepared. In the first paper, the structure of Sb0. READ MORE

  7. 5. Soil improvement based on environmental geotechnics : environmental and geotechnical aspects of drainage of redox-sensitive soils and stabilisation of soils with by-products

    Author : Josef Mácsik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : I avhandlingen behandlas Miljögeotekniska problem som "dränering av redox-sensitiva jordar", "blockstabilisering av sulfidjord och torvjord" och " undersökning av nya vägmaterial". - Miljöproblem, kopplat till dränering och/eller urgrävning av redox-sensitiva jordar, som järnhaltiga moräner och sulfidjordar, behandlas i denna avhandling.
