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

    Author : Göran Wiberg; KTH; []
    Keywords : ;

    Abstract : 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. READ MORE

  4. 2. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

    Author : Wenxiao He; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; superstructure; lyotropic liquid crystal; self-assembly; Calcium phosphate; bone-like apatite; amphiphilic peptide; nanocomposite; biomimetic mineralization;

    Abstract : 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.

  5. 3. Membrane Orientation Studies with Polarized Light Spectroscopy

    Author : Malin Ardhammar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipid vesicle; membrane orientation; flow linear dichroism; oriented circular dichroism;

    Abstract : 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. READ MORE

  6. 4. Developing novel diffusion MRI methods for comprehensive analysis of restricted and anisotropic self-diffusion system

    Author : Hong Jiang; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRI; diffusion; tissue microstructure; heterogeneity; diffusion encoding; q-vector; ;

    Abstract : Diffusion MRI is a non-invasive imaging technique used to study the microstructural properties of biological tissues by observing the self-diffusion of water molecules. Traditional diffusion MRI methods, based on the pulsed gradient spin-echo sequence, employ magnetic field gradients to encode information about translational motion. READ MORE
