  1. 11. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution

    Författare :Daniel Svensson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; bentonite; smectite; freezing; thawing; hydration; intercalation; four-water-layer; ethylene glycol; X-ray diffraction; time-resolved; spatial-resolution; XANES; Fe; redox; iron; ABM; TBT; Äspö;

    Sammanfattning : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. LÄS MER

  3. 12. Nutritional Properties of Liquid Oats as Affected by Processing and Storage

    Författare :Huanmei Zhang; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Antioxidants; Avenanthramides; Biological value; Iron absorption; Fatty acids; Processing; Minerals; Vitamins; Storage; Stability; Nutritional properties; Oats; Beverage; Bioteknik;

    Sammanfattning : The cholesterol-lowering effects of oats have led to an increasing interest in them on the food market. Liquid oats has emerged as a new way of consuming oats and has become a commercial product. LÄS MER

  4. 13. Investigation of Interactions between Liquid Iron Containing Oxygen and Aluminosilicate Refractories

    Författare :Era Kapilasharmi; KTH; []
    Nyckelord :;

    Sammanfattning : The present work was initiated to investigate runnerrefractory corrosion by molten steel. The aim was to understandthe mechanism of inclusion formation during ingot casting. Thework is also of interest to other unit processes in steelmaking, where refractory corrosion and erosion are seriousproblems. LÄS MER

  5. 14. Optimizing liquid phase sintering of ferrous powder metallurgical materials

    Författare :Henrik Borgström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface chemical analysis high speed steel; Vacuum annealing; nitrogen alloying; liquid phase sintering;

    Sammanfattning : The properties of powder metallurgical, PM, components are dependent on that the dilemma of full density and suitable microstructure is resolved. Whilst it is often possible to achieve full density, it may or may not coincide with a suitable microstructure. LÄS MER

  7. 15. Chemical-Looping Combustion with Liquid Fuel — Operation in a 300W Chemical-Looping Combustor

    Författare :Patrick Moldenhauer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oxygen carrier; kerosene; circulated fluidized bed CFB ; liquid fuel; CO2 capture; chemical-looping combustion CLC ;

    Sammanfattning : Chemical-looping combustion (CLC) is a promising technology for future energy production based on combustion of fossil fuel with inherent CO2 separation. In comparison to other carbon capture technologies there is no need for energy demanding gas separation using CLC in order to obtain pure CO2. LÄS MER
