    Författare :Per Kjellin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesostructures; CdS; calcium carbonate; self-assembling phases; calcite; CaCO3; Ag; crystal polymorphs; nanostructures; surface active polymers; SrCO3;

    Sammanfattning : This thesis concerns effects of polymeric surfactants on the crystal growth of inorganic structures. The crystal growth of calcium carbonate on steel surfaces was studied with a heat exchanger cell and with an electrochemical method. LÄS MER

  3. 2. Understanding Physical Reality via Virtual Experiments

    Författare :Sergiu Arapan; Rajeev Ahuja; Börje Johansson; Chris Pickard; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; ab initio calculations; electronic structure; lattice dynamics; high-pressure phase transitions; high-temperature phase transitions; incommensurate structures; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : In this thesis I have studied some problems of condensed matter at high pressures and temperatures by means of numerical simulations based on Density Functional Theory (DFT).The stability of MgCO3 and CaCO3 carbonates at the Earth's mantle conditions may play an important role in the global carbon cycle through the subduction of the oceanic crust.

  4. 3. Intrinsic kinetics of some high temperature gas-solid reactions

    Författare :Ioannis Arvanitidis; KTH; []
    Nyckelord :;

    Sammanfattning : Many materials processes are based on gas-solid reactions.An understanding of the mechanisms underlying these reactionsis essential for optimization of the process parameters andinvention of new process routes. LÄS MER
