  3. 2. Organic Synthesis in Nonionic Microemulsions

    Författare :Maria Häger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic reaction; phase behaviour; microemulsion; reaction kinetics;

    Sammanfattning : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. LÄS MER

  4. 3. Self-Assembling Surfactant Aggregates for Synthesis of Nanomaterials

    Författare :Martin Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-assembly; Ag; photocatalysis; nanoparticles; surfactants; liquid crystals; microemulsions; rutile; mesoporous materials; CaCO3; anatase; TiO2;

    Sammanfattning : The main objective of this thesis was to study how surfactant assemblies can be used as templates to form inorganic nanomaterials. Both water-in-oil microemulsions and liquid crystalline phases have been used as structure directing agents. LÄS MER

  5. 4. Polymer effects on microemulsions and lamellar phases

    Författare :Håkan Bagger-Jörgensen; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poisson-Boltzmann equation; hard sphere; osmometry; small angle scattering; phase behaviour; hydrophobically modified polyelectrolyte; hydrophobically modified polymer; nonionic surfactant; microemulsion; lamellar phase; undulation force; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The main part of this thesis deals with the effects of adsorbing and non-adsorbing polymers when mixed with microemulsion droplets and bilayers in a lamellar phase. The phase behaviour, microstructure and interactions in a nonionic surfactant/ water/ oil-system, comprising penta ethylene oxide dodecyl ether (C12E5) and decane, was investigated. LÄS MER
