   Sammanfattning : This thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. LÄS MER

3. 7. Computational Modeling of the Dynamics of Fluid-Filled Porous Media with Application to Road and Railway Structures

   Författare :Bernd Lenhof; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road; hydro-mechanical modeling; poromechanics; railway; porous media; binary phase mixture;

   Sammanfattning : The dynamics of fluid-saturated porous media is a challenging topic with applications in many engineering fields like, e.g., road and railway mechanics. The complexity of the problem requires high computational effort when performing simulations of the coupled dynamic deformation and fluid flow in a saturated porous medium. LÄS MER

4. 8. Catanionic Surfactant Mixtures and Binary Systems of Modified Fatty Acid Surfactants. Phase Equilibria and Structure

   Författare :Malin Bydén Sjöbom; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coacervation; asymmetry; bile salt; didodecyldimethylammonium bromide; Physical chemistry; Fysikalisk kemi; catanionic surfactant mixture; intermediate phase; a-methylsubstituted sodium carboxylate; dodecylpyridinium bromide; ionic surfactant; polarizing microscopy; FT-PGSE self-diffusion; 2H NMR; SAXS; liquid crystal; micelle; phase equilibria; phase diagram;

   Sammanfattning : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

5. 9. Modeling adsorption of organic compounds on activated carbon : a multivariate approach

   Författare :Jufang Wu; Anders Cedergren; Ingrid Fängmark; Ola Claesson; Lars-Gunnar Hammarström; Fritz Stoeckli; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; activated carbon; adsorption; adsorption capacity; adsorption rate; PCA; PLS; binary mixtures; Dubinin-Radushkevich; Wheeler-Jonas; Analytisk kemi; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

   Sammanfattning : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. LÄS MER

7. 10. Drying of Multicomponent Liquid Films

   Författare :Fabio Luna; KTH; []
   Nyckelord :ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

   Sammanfattning : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. LÄS MER
