1. 6. Total internal reflection ellipsometry

   Författare :Michal Poksinski; Uwe´ Beck; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : This thesis summarizes the work performed on the development and implementation of the optical measurement technique called total internal reflection ellipsometry (TIRE).The TIRE principle is based on spectroscopic ellipsometry performed under conditions of total internal reflection.

3. 7. Immobilization and Interaction of Biomolecules at the Solid-Liquid Interface : Applications to Solid-Phase Analytical Techniques

   Författare :Ulf Jönsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein immobilization; silica; Immunoglobulins; Protein A; Fibronectin; chemical-vapour deposition; silane; ellipsometry; radiolabeling; contact-angle measurement; solid-phase analytical techniques;

   Sammanfattning : The development of solid-phase-analytical techniques based on surface-concentration-measuring devices requires a stable and reproducible immobilization of biomolecules on well-characterized solid surfaces. This study reports on the immobilization of Immunoglobulin G, Protein A and Fibronectin on chemically modified silica surfaces. LÄS MER

4. 8. Tunable photonic crystals based on carbon nanofibers

   Författare :Robert Rehammar; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FDTD; PECVD; Photonic crystal; carbon nanofiber; tunable; diffraction; ellipsometry;

   Sammanfattning : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range, i.e. structures with changeable optical properties. LÄS MER

5. 9. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems

   Sammanfattning : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. LÄS MER

7. 10. Optical Characterization and Optimization of Display Components : Some Applications to Liquid-Crystal-Based and Electrochromics-Based Devices

   Författare :Iryna Valyukh; Claes-Göran Granqvist; Ewa Wäckelgård; Hans Arwin; Ola Hundery; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ellipsometry; liquid crystal; LCD; optical anizotropy; electrochromic; inverse problems; Optics; Optik; Optical physics; Optisk fysik; Numerical analysis; Numerisk analys; Solid State Physics; fasta tillståndets fysik; Information Systems; data- och systemvetenskap;

   Sammanfattning : This dissertation is focused on theoretical and experimental studies of optical properties of materials and multilayer structures composing liquid crystal displays (LCDs) and electrochromic (EC) devices. By applying spectroscopic ellipsometry, we have determined the optical constants of thin films of electrochromic tungsten oxide (WOx) and nickel oxide (NiOy), the films’ thickness and roughness.
