  4. 2. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems

    Author : Johan Reimer; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; micellar network; NMR diffusometry; microemulsion; microstructure; phase diagram; phase separation; phase behaviour; alkyl glucoside; sugar surfactant;

    Abstract : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. READ MORE

  5. 3. Alkylglucosides - physical chemical properties

    Author : Frederik Nilsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Abstract : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. READ MORE

  6. 4. Association and Microstructure in Self-Assembling Catanionic Systems

    Author : Eduardo Marques; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFG NMR self-diffusion; cryogenic-transmission electron microscopy; catanionic systems; gels; bile salts; polyelectrolytes; liquid crystals; vesicles; Surfactants; phase diagrams; light microscopy; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : This thesis addresses the phase behavior and phase structure in mixed surfactant-surfactant and surfactant-polymer systems, where the co-solutes have opposite charges (catanionic systems). The initial goal has been to investigate self-assembly aspects in mixtures of single-/double-chained surfactants and bile salt/double-chained surfactants, with the main focus on vesicle assembly in dilute regions.

  7. 5. Atomic-scale investigation of interfacial structures in WC-Co at finite temperatures

    Author : Erik Fransson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; complexions; phase diagrams; interfaces; force constants; cluster expansions; atomic-scale modeling; free energies; cemented carbides; WC--Co;

    Abstract : WC-Co cemented carbides combine superb hardness with high toughness making them ideal for usage in high-speed machining of steels and in wear resistance tools. These excellent mechanical properties are to a large extent dependent on the microstructure and thus the interfacial properties of the material. READ MORE
