3. 2. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems

   Författare :Johan Reimer; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; micellar network; NMR diffusometry; microemulsion; microstructure; phase diagram; phase separation; phase behaviour; alkyl glucoside; sugar surfactant;

   Sammanfattning : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. LÄS MER

4. 3. Structure Evolution during Phase Separation and Gelation of Biopolymer Mixtures

   Författare :Niklas Lorén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; gelatin maltodextrin; biopolymer mixtures; structure evolution; phase separation; stereology; confocal laser scanning microscopy; image analysis; spinodal decomposition; transmission electron microscopy; gelation;

   Sammanfattning : This thesis focuses on the kinetics of phase separation and gelation in aqueous mixtures of gelatin and maltodextrin. The structure evolution of these mixtures at different length scales was recorded by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The microstructure was quantified by image analysis. LÄS MER

5. 4. Structure evolution of spin-coated phase separated EC/HPC films

   Författare :Pierre Carmona; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin-coating; controlled drug release; porous film; drug delivery; confocal laser scanning microscope; kinetics; phase separation mechanisms; cellulose; biopolymer; phase separation;

   Sammanfattning : Porous phase-separated films made of ethylcellulose (EC) and hydroxypropylcellulose (HPC) are commonly used for controlled drug release. The structure of these thin films is controlling the drug transport from the core to the surrounding liquid in the stomach or intestine. However, detailed understanding of the structure evolution is lacking. LÄS MER

7. 5. Phase-field modeling of diffusion controlled phase transformations

   Författare :Irina Loginova; KTH; []
   Nyckelord :phase-field; dendritic growth; grain boundary; Widmanstaetten plate; solidification;

   Sammanfattning : Diffusion controlled phase transformations are studied bymeans of the phase-field method. Morphological evolution ofdendrites, grains and Widmanst\"atten plates is modeled andsimulated.Growth of dendrites into highly supersaturated liquids ismodeled for binary alloy solidification. LÄS MER
