5. 4. Development of Nonlinear Microscopy for Studies of Metabolism and Tissue Engineering

   Författare :Madeleine Åkeson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; imaging; bacterial cellulose; nonlinear microscopy; Saccharomyces cerevisiae; yeast; C. elegans; Microscopy; lipid storage;

   Sammanfattning : Nonlinear microscopy techniques provide abilities for noninvasive and selective imaging of structural and chemical properties of biological systems. These techniques include coherent anti-Stokes Raman scattering (CARS) microscopy with the ability to selectively image molecular vibrations, second harmonic generation (SHG) microscopy which selectively images fiber structures, and third harmonic generation (THG) microscopy which is sensitive to interfaces between materials with different optical properties.

7. 5. Association and Microstructure in Self-Assembling Catanionic Systems

   Författare :Eduardo Marques; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFG NMR self-diffusion; cryogenic-transmission electron microscopy; catanionic systems; gels; bile salts; polyelectrolytes; liquid crystals; vesicles; Surfactants; phase diagrams; light microscopy; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

   Sammanfattning : This thesis addresses the phase behavior and phase structure in mixed surfactant-surfactant and surfactant-polymer systems, where the co-solutes have opposite charges (catanionic systems). The initial goal has been to investigate self-assembly aspects in mixtures of single-/double-chained surfactants and bile salt/double-chained surfactants, with the main focus on vesicle assembly in dilute regions.
