16. 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
17. Strong L^1 convergence to equilibrium without entropy conditions for the spatially homogenous Boltzmann equation
Sammanfattning : .... LÄS MER
18. First Principles Calculations of Electron Transport and Structural Damage by Intense Irradiation
Sammanfattning : First principle electronic structure theory is used to describe the effect of crystal binding on radiation detectors, electron transport properties, and structural damage induced by intense irradiation. A large database containing general electronic structure results to which data mining algorithms can be applied in the search for new functional materials, a case study is presented for scintillator detector materials.

19. Diffusion studies in gels using holographic laser interferometry
Sammanfattning : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

20. Electronic Transport in Strained Materials
Sammanfattning : In this thesis the conductivity of strained materials has been investigated using density functional theory and a semiclassical transport theory based on the Boltzmann equation.In transition metals trends are reproduced without adjustable parameters. LÄS MER
