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

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

    Abstract : 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. READ MORE

  4. 2. Catanionic Surfactant Mixtures and Binary Systems of Modified Fatty Acid Surfactants. Phase Equilibria and Structure

    Author : Malin Bydén Sjöbom; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coacervation; asymmetry; bile salt; didodecyldimethylammonium bromide; Physical chemistry; Fysikalisk kemi; catanionic surfactant mixture; intermediate phase; a-methylsubstituted sodium carboxylate; dodecylpyridinium bromide; ionic surfactant; polarizing microscopy; FT-PGSE self-diffusion; 2H NMR; SAXS; liquid crystal; micelle; phase equilibria; phase diagram;

    Abstract : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

  5. 3. Phase equilibria and thermodynamic properties of high-alloy tool steels : theoretical and experimental approach

    Author : Johan Bratberg; John Ågren; Bengt Hallstedt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermodynamic modelling; thermodynamic calculations; tool steels; high-speed steels; CALPHAD; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : The recent development of tool steels and high-speed steels has led to a significant increase in alloy additions, such as Co, Cr, Mo, N, V, and W. Knowledge about the phase relations in these multicomponent alloys, that is, the relative stability between different carbides or the solubility of different elements in the carbides and in the matrix phase, is essential for understanding the behaviour of these alloys in heat treatments.

  6. 4. Crystal structures and phase equilibria in the Mn-Ga system

    Author : Magnus Boström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Mn-Ga equilibrium phase diagram was reinvestigated. The phase analyses were performed both by powder and single crystal X-ray diffraction methods. READ MORE

  7. 5. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    Author : Anna Karin Morén; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phase equilibria; Protein-surfactant interactions; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Abstract : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. READ MORE
