  2. 21. Preparation and Characterisation of Sputtered Titanium- and Zirconium Nitride Optical Films

    Author : Kent Andersson; Arne Roos; M. Georgson; Uppsala University Department of Technology Solid State Physics Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Multilayered interference coatings based on titanium- and zirconium nitride and designed for solar control have been prepared using reactive d c magnetron sputtering. Preparation effects and degradation mechanisms were investigated. It was shown that the quality of the nitride strongly depends on the degree of crystallinity in the underlying oxide. READ MORE

  4. 22. Protein Engineering on Azurin. Expression Mutagenesis and Characterisation of Copper Site Mutants

    Author : B Göran Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EPR spectroscopy; cassette mutagenesis; optical spectroscopy; amino acid exchange; Escherichia coli; electron transfer; reduction; azurin;

    Abstract : Azurin belongs to a family of small blue copper proteins or cupredoxins which participate in electron transfer processes in plants and bacteria. The type 1 copper site in these proteins is characterised by an intense blue colour, a narrow hyperfine coupling in the EPR signal and, generally, a high reduction potential. READ MORE

  6. 24. Nonlinear Optical Materials Structural Studies of Alkali Titanium Phosphates

    Author : Stefan Norberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optical materials; alkali titanium phosphates; phase transition; alkaline cation shifts; rare-earth langbeinites; doped KTP isostructures;

    Abstract : Crystals are beautiful, not only as pieces of jewellery, but also for their intrinsic properties, which are of significant scientific and technological importance. Ferroelectric materials are extremely versatile, since they may be combined with piezoelectric or electrooptic devices for use as filters, oscillators, memories, light detectors, and displays.
