  1. 1. Devlopment and relaxation of orientation in liquid crystalline polymers : transport properties of liquid crystalline polymer blends

    Författare :Göran Wiberg; KTH; []
    Nyckelord :;

    Sammanfattning : In this thesis different types of liquid crystallinepolymers have been investigated with respect to build up andrelaxation of orientation. The potential of making new barriermaterials using liquid crystalline polymer blends was alsostudied. LÄS MER

  2. 2. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

    Författare :Wenxiao He; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; superstructure; lyotropic liquid crystal; self-assembly; Calcium phosphate; bone-like apatite; amphiphilic peptide; nanocomposite; biomimetic mineralization;

    Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

  3. 3. On the Phase Behaviour of Lipids with Respect to Skin Barrier Function

    Författare :Johan Engblom; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycerol monooleate; cholesterol; fatty acids; azone; bicontinuous mesophases; phase behaviour; lipid polymorphism; Stratum corneum; skin penetration; X-ray; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : The aim of this thesis has been to provide further understanding of skin barrier function from a chemical point of view. The main barrier is known to be located in the outermost layer of the skin, stratum corneum, composed of cornified flattened cells in conjunction with an extracellular lipid-water matrix. LÄS MER

  4. 4. Membrane Orientation Studies with Polarized Light Spectroscopy

    Författare :Malin Ardhammar; Chalmers University of Technology; []
    Nyckelord :lipid vesicle; membrane orientation; flow linear dichroism; oriented circular dichroism;

    Sammanfattning : Lipid vesicles are versatile tools in modern biophysical science. They can be used as models of the cell membrane, to examine permeability, stability and behavior of molecules in the bilayer. They may act as transporters in a pharmacological context, designed to deliver their cargo to a certain place in the patient. LÄS MER
