4. 2. Self-assembly in Melts of Block copolymer-based Systems Featuring Supramolecular Interactions

   Author : Mehran Asad Ayoubi; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hierarchical self-assembly; melt; block copolymer; cationic surfactant; non-ionic surfactant; supramolecular interactions; microphase separation; Linear-b-AmphComb;

   Abstract : The subject of this thesis is experimental investigation of self-assembly in solvent-free (ionic) macromolecular systems that contain block copolymer chains as the basic constituent component in combination with low molecular weight amphiphiles. In particular, especial attention is paid to study thoroughly a new class of block copolymer-based ionic supramolecules, named as Linear-b-AmphComb, that feature novel hierarchical self-assembly characteristics.

5. 3. Characterisation of Aqueous Solutions, Liquid Crystals and Solid State of Non-ionic Polymers in Association with Amphiphiles and Drugs

   Author : Annika Ridell; Martin Malmsten; Sven Engström; David Attwood; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polymer; surfactant; phase diagram; x-ray diffraction; fluorescence spectroscopy; calorimetry; PEG; cellulose ether; viscometry; cubic phase; liquid crystals; drugs; solid dispersion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

   Abstract : Cellulose ethers and polyethylene glycols are used in drug formulations as water swelling or water soluble matrices. Polar lipids, for example monoglycerides, and surfactants can be used to solubilise hydrophobic or amphiphilic drugs and to formulate potential drug delivery vehicles such as emulsions, liposomes and cubic phases.

6. 4. Protein-surfactant interactions

   Author : Ank Valstar; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

   Abstract : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. READ MORE

7. 5. Colloidal suspensions of mesostructured silica

   Author : Andreas Berggren; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; formation mechanism; non-ionic surfactants; silica; inorganic silica; colloidal suspension; control of particle size;

   Abstract : Mesoporous silica is a porous material with walls made of silica and pores in the size range of 2-50 nm. Since the silica most often is amorphous, the material lacks short range order but the pores may be arranged in different structures generating a long-range order. READ MORE
