  1. 1. NMR Self-Diffusion Studies and Stability Studies of Emulsions

    Author : Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

    Abstract : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. READ MORE

  2. 2. Black liquor gasification : experimental stability studies of smelt components and refractory lining

    Author : Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; Chemical energy engineering; Kemisk energiteknik;

    Abstract : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). READ MORE

  3. 3. A theoretical investigation of Tin+1AlCn and Mn2GaC MAX phases : phase stability and materials properties

    Author : Andreas Thore; Johanna Rosén; Björn Alling; Linköpings universitet; []

    Abstract : This thesis presents theoretical research on MAX phases (M=transition metal, A=A-group element, X=carbon and/or nitrogen), with focus on predictions of phase stability as well as of physical properties.The first part is an investigation of the phase stability of the MAX phases Ti2AlC, Ti3AlC2, and Ti4AlC3 at elevated temperatures, where the former two phases have been obtained experimentally.

  4. 4. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    Author : Anna Karin Morén; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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

  5. 5. Structure and Phase Stability of Polyelectrolyte-Macroion Solutions

    Author : Marie Skepö; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; hydrophobicity; spatially distributed interaction sites; protein-polymer interaction; Monte Carlo Simulations; redissolution; phase separation; cluster; complex; Polyelectrolytes; macroions;

    Abstract : Polyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. READ MORE
