  1. 1. Theoretical Studies of Surface Forces and Phase Equilibria

    Författare :Jan Forsman; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; simulations; phase equilibria; hydrophobic interactions; hydration; Fysikalisk kemi; Physical chemistry;

    Sammanfattning : The interaction between large hydrophobic and hydrophilic surfaces in aqueous solution is investigated, using Metropolis Monte Carlo simulations and density functional theory. Special attention is devoted to the solvation force and its dependence on the nature of the solvent-solvent and solvent-surface interactions. LÄS MER

    Författare :Christopher Tholander; Björn Alling; Lars Hultman; Ferenc Tasnádi; Liverius Lymperakis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The last hundred years have been full of scientific discoveries leading to technological advances, such as, computers, smart phones, etc. Most of the advances would not have been possible without new discoveries within the vast field of materials science. LÄS MER

  4. 3. Free Energy and Surface Forces in polymer systems: Monte Carlo Simulation Studies

    Författare :Andrei Broukhno; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolytes; electrostatic interactions; phase transitions; colloidal stability; surface forces; Monte Carlo simulation; free energy evaluation; polyampholytes; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. LÄS MER

  5. 4. Amphiphilic Molecules in Aqueous Solution

    Författare :Gerd Persson; Göran Lindblom; Håkan Edlund; Björn Lindman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.

  7. 5. Crystallization in additive manufacturing of metallic glass

    Författare :Anders Ericsson; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amorphous metals; Crystallization; Laser powder bed fusion; Neutron scattering; Phase-field theory; Classical nucleation theory;

    Sammanfattning : Metallic glasses are non-crystalline metals that are obtained by rapid cooling of the melt to bypass crystallization. The amorphous atomic structure shows enhanced properties relative to the crystalline counterpart. For example, enhanced mechanical properties, improved corrosion resistance, as well as excellent soft magnetic properties. LÄS MER
