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

17. Study on some phenomena of slag in steelmaking process
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
18. Strength in Numbers – Droplet Microfluidics for Multicellular Ensemble Applications
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.

19. Polymer effects on microemulsions and lamellar phases
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
20. Self-Assembling Surfactant Aggregates for Synthesis of Nanomaterials
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
