  2. 1. Oxidative Dissolution of Spent Fuel and Release of Nuclides from a Copper/Iron Canister : Model Developments and Applications

    Author : Longcheng Liu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model; oxidative dissolution; spent fuel; radiolysis; release; mass transport; radionuclide; hydrogen; corrosion; canister; near field; repository; Chemical engineering; Kemiteknik;

    Abstract : Three models have been developed and applied in the performance assessment of a final repository. They are based on accepted theories and experimental results for known and possible mechanisms that may dominate in the oxidative dissolution of spent fuel and the release of nuclides from a canister.

  4. 2. Nanoscale Reaction Systems

    Author : Karin Fromell; Karin Caldwell; Francesco Dondi; Uppsala universitet; []
    Keywords : Life sciences and physical sciences; nanoparticles; Sedimentation Field-Flow Fractionation; bioaffinity; multilayered functionalization; protein attachment; diagnostics; bioluminescence; NATURVETENSKAP;

    Abstract : The work presented in this thesis describes the use of polystyrene nanoparticles as model surfaces for bioanalytical work. Nanoparticles constitute convenient platforms for the attachment of bioactive agents, and receptor coated particles offer high local concentration of binding sites for specific ligands with minimal steric hindrance.

  5. 3. Mass transfer and slag-metal reaction in ladle refining : a CFD approach

    Author : Eva Ramström; Du Sichen; Mselly Nozotta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reoxidation; desulphurisation; CFD; ladle treatment; model; Other materials science; Övrig teknisk materialvetenskap;

    Abstract :   In order to optimise the ladle treatment mass transfer modelling of aluminium addition and homogenisation time was carried out. It was stressed that incorporating slag-metal reactions into the mass transfer modelling strongly would enhance the reliability and amount of information to be analyzed from the CFD calculations.

  6. 4. Redox models in chemistry : A depiction of the conceptions held by secondary school students of redox reactions

    Author : Lise-Lotte Österlund; Margareta Ekborg; Anders Berg; Christiane Funk; Astrid Bulte; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; science education; redox reaction; model; inorganic chemistry; organic chemistry; biochemistry; students conceptions; textbook; Other chemistry; Övrig kemi; didactics of chemistry; kemididaktik;

    Abstract : According to previous research, students show difficulties in learning redox reactions. By the historical development different redox models exist to explain redox reactions, the oxygen model, the hydrogen model, the electron model and the oxidation number model. READ MORE

  7. 5. Investigations of Reaction Cross Sections for Protons and 3He

    Author : Mattias Lantz; Anders Ingemarsson; Livius Trache; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; reaction cross section; protons; 3He; experimental method; transmission method; optical model; parametrization; matter distributions; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : The reaction cross section gives the probability that a particle will undergo a nonelastic process when passing through a nuclear medium. Therefore reaction cross section data are of importance both for theoretical studies and for applications in such diverse fields as medicine, biology, astrophysics and accelerator-driven transmutation of nuclear waste.
