  2. 21. On the colloidal and molecular aspects of peptide self-assembly

    Author : Axel Rüter; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide self-assembly; Aggregation kinetics; Peptide hydrogel; Small angle scattering; Rheology;

    Abstract : Peptide self-assembly is a spontaneous process, ubiquitous in nature for the creation of highly ordered and complex biological structures, making it a sought after technique in the development of novel biocompatible materials. The process is also strongly associated with various neurodegenerative diseases in the formation of amyloid plaques in diseases such as Alzheimer’s and Parkinson’s, where fully functioning proteins aggregate are reassembled into nonfunctional fibrillar aggregates that eventually lead to cell death.

  4. 22. Lipid Self-Assembly and Lipase Action

    Author : Johanna Borné; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; specific activity.; Physical chemistry; Fysikalisk kemi; vesicles; cubosomes; liquid crystalline phases; sodium oleate; oleic acid; diolein; monoolein; Oleic acid based acyl glycerols; Thermomyces lanuginosa lipase;

    Abstract : In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic acid (OA), sodium oleate (NaO) and glycerol .

  6. 24. 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.

  7. 25. Self-Assembly in Lipid-Protein Systems : Lung Surfactant, Stratum Corneum and Model Membranes

    Author : Jenny Andersson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lipid self-assembly; lung surfactant; stratum corneum; dehydrin; cholesterol; osmolytes; urea; TMAO; ssNMR; cSAXS;

    Abstract : This thesis explores lipid self-assembly and aims to give a broad picture of self-assembly structures in simple and complex lipid-protein systems. The systems studied are lung surfactant, stratum corneum and simple model membranes. The lung surfactant mixture lines the alveolus in our lungs and stabilises the air- tissue interface. READ MORE
