  1. 16. Emulsion formation and stability - Impact of the dispersed state of the emulsifier on emulsification

    Författare :Emma Magnusson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emulsion; phospholipid; dispersed state; field flow fractionation; freeze-thaw stability;

    Sammanfattning : Emulsions find a variety of applications in for example food, cosmetics and pharmaceutical preparations. In order to obtain emulsions with desired properties it is important to understand how different factors, such as the properties of the emulsifier and the emulsification procedure, impact the final emulsion properties.

  2. 17. Study on some phenomena of slag in steelmaking process

    Författare :Liushun Wu; Sichen Du; Carlo Mapelli; KTH; []
    Nyckelord :Slag viscosity; calcium fluoride; fluid viscosity with particles; mixture viscosity; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present work is to study slag phenomena in steelmaking process. In order to attain thegoal, a number of high temperature experiments and simulation experiments were carried out. Four master slags were used to study the effect of CaF2 on slag viscosity. LÄS MER

  3. 18. Strength in Numbers – Droplet Microfluidics for Multicellular Ensemble Applications

    Författare :Martin Trossbach; Aman Russom; Håkan Jönsson; Nicole Pamme; KTH; []
    Nyckelord :Droplet Microfluidics; High-Throughput Screening; Microtissues; Microreactors; Cell Factories; Cell Culture; Biomaterials; Spheroids; Biotechnology; Bioteknologi;

    Sammanfattning : The work presented in this doctoral thesis explores multicellular, biological, and biotechnological applications for microfluidic droplets, making use of a number of unique features of these miniaturized, highly scalable reaction vessels.Droplet microfluidics specializes in pico- to nanoliter sized aqueous droplets in an immiscible oil phase, borrowing techniques from the field of microfluidics, namely fluid actuation, detection systems and electronic peripherals.

  4. 19. 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

  5. 20. 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
