  2. 16. Preparation and characterization of sputtered metal oxides and nitrides for optical applications

    Author : Monica Veszelei; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : Sputter deposited metal oxide and nitride thin films have been studied for energy-efficient window applications. Coatings, for both static and dynamic control of radiative heat transfer through windows, were optically characterized. As metal base in static solar selective coatings, semi-transparent TiN and ZrN films have been investigated. READ MORE

  4. 17. Bi-based high Tc superconductors and enhancement of critical current density

    Author : Shi-ju Guo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Basic bulk high temperature superconductors in the Bi-Sr-Ca-Cu-O system and the BiPb-Sr-Ca-Cu-O system were prepared through the solid state reaction route and the coprecipitation method. The formation of 110 K phase promoted by partial Pb substitution for Bi was studied. Effects of heat treatment on 110K phase formation were studied. READ MORE

  5. 18. Charge Transport in Transition Metal Oxide Thin Films and Electrochromic Devices

    Author : AnnaKarin Jonsson; Bengt-Erik Mellander; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik; Engineering physics; Teknisk fysik; Solid State Physics; Fasta tillståndets fysik;

    Abstract : Thin film devices for windows, mirrors, space applications and other purposes, have become an essential part of modern technology. A great advantage with a thin film device is the small amount of material used and the compact volume of the device. READ MORE

  6. 19. Structural Silicides - Processing, Microstructure and Toughening

    Author : Danqing Yi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toughening; solid solubility; processing; microstructures; mechanical properties; composites; silicides; crystal structure; alloying effects; phase transformation;

    Abstract : Molybdenum disilicide is a promising candidate material for high temperature structural uses. However, its room-temperature toughness is rather low and has to be improved. The objective of this thesis is to improve the fracture toughness of MoSi2 by alloying and composite processes. READ MORE

  7. 20. All-Thin-Film Electrochromic Devices for Optical and Thermal Modulation

    Author : Anna-Lena Larsson; Gunnar A Niklasson; Lars Stenmark; Michael G Hutchins; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : The optical properties of electrochromic materials can be changed by application of an electrical voltage. The conventional electrochromic device consists of several thin films of electrochromic materials and layers for electron- and ion conduction. READ MORE
