  3. 2. On the Optics and Surface Physics of Liquid Crystals

    Författare :Pontus Jägemalm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; deformed helix; anchoring; short-pitch; SiO; homogeneous models; two-fold degenerate alignment; Berreman; bistable alignment; optical activity;

    Sammanfattning : Good knowledge about optics and surface physics of liquid crystals is indispensable when utilising them for applications, such as liquid crystal displays (LCDs). However, they are also two central subjects in fundamental research on liquid crystals. LÄS MER

  4. 3. DNA Electrophoresis: Optical Probing and Microscopic Imaging to Understand Separation Mechanisms

    Författare :Anette Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical probing; YOYO; polarized light spectroscopy; DNA electrophoresis; DAPI; binding modes; helix alignment; fluorescence microscopy;

    Sammanfattning : The aim of this work was to combine spectroscopic, mobility, and fluorescence microscopy studies to elucidate the mechanisms behind DNA electrophoresis, a method to separate DNA molecules according to size. The microscopy studies require staining of the DNA with a fluorescent dye. LÄS MER

  5. 4. Keratinocyte differentiation. Involvement of the growth hormon (GH)/insulinlike growth factor1 (IGFI) axis and IGF1 post receptor signaling

    Författare :Elisabeth Björntorp Mark; Göteborgs universitet; []
    Nyckelord :IGF1R; GH; Id1; keratinocytes; psoriasis;

    Sammanfattning : At cellular level, little is known about the genes that regulate keratinocyte differentiation andproliferation. Psoriasis is regarded as a T-cell mediated inflammatory disease with hyperproliferativekeratinocytes. LÄS MER

  7. 5. The Flexoelectro-Optic Effect in Cholesteric Liquid Crystals

    Författare :Per Rudquist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The flexoelectrooptic effect in cholesteric liquid crystals is based on a linear coupling of the medium with an applied electric field. The electric field causes the optic axis, which is coinciding with the helix axis of the hardtwisted cholesteric (pitch... LÄS MER
