  1. 1. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

    Författare :Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

    Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. LÄS MER

  3. 2. Oxidation kinetics of nickel particles

    Författare :Richard Karmhag; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Oxidation; kinetics; nickel; particles; UFP; solar absorber; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Nanoparticles have an immense surface to volume ratio. This is a key factor to the new properties of some materials made up of such particles. The oxide layer formed on all materials will have a large influence on the behaviour of these materials. The layer isadvantageous in some cases but causes problems in other. LÄS MER

  4. 3. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

    Författare :Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

    Sammanfattning : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. LÄS MER

  5. 4. Hydrodemetallization of Petroleum - Reaction Kinetics, Activity Decay and Long-life Catalysts

    Författare :Fei-Xiang Long; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalyst deactivation; large pore catalyst; hydroprocessing; hydrodemetallization; fibrillar alumina support; hydrotreating; kinetics; metal porphyrin; multiresponse parameter estimation; HDM;

    Sammanfattning : Hydrodemetallization (HDM) is an indispensable step in industrial catalytic hydroprocessing of residual oils. To develop improved HDM catalysts and reactors, a detailed knowledge of the reaction mechanisms and kinetics, and a good understanding of the mechanisms and process of the catalyst decaying are very important.

  7. 5. Volume kinetics of glucose solutions given by intravenous infusion

    Författare :Fredrik Sjöstrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Volume kinetics; osmosis; dehydration; rehydration; glucose solutions; glucose; hypovolemia; hypoglycemia; fluids; intravenous fluid therapy; fluid shifts; plasma volume; dilution; plasma dilution; intracellular hydration; central volume.;

    Sammanfattning : Fluid therapy is often cumbersome to plan since the distribution and the elimination of the administered solution are difficult to analyze in the clinical setting. The knowledge of the adequate rate and dose for each individual patient and under various physiological conditions would be very attractive to obtain in order to avoid fluid overload and hyperglycemia.
