  1. 1. Structural investigation of Nb-based layer sulfides

    Författare :Alexander Grippa; Sven Lidin; Pedro Berastegui; Carlos Otero Díaz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nb-based sulfides; misfit layered; structure determination; electron diffraction; Chemistry; Kemi;

    Sammanfattning : In this work we have investigated the intercalation of electron-donors between NbS2 slabs in Nb-based layer sulfides.Two series of Sr substituted Nb-based misfit sulfides belonging to the 1.5Q/1H and 1Q/1H series of misfit layer compounds have been synthesised. LÄS MER

  3. 2. Flexible inorganic and hybrid thermoelectric thin films based on layered calcium cobaltate

    Författare :Binbin Xin; Per Eklund; Biplab Paul; Niclas Solin; Jiri Houska; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetron sputtering; Nanoporous Ca3Co4O9; Thermoelectric; Flexibility;

    Sammanfattning : With the development of wearable and miniaturized electronics, self-sustaining energy sources have drawn extensive attention. Flexible thermoelectric materials and devices is an approach to convert waste heat into electricity as continuous power supply for such applications. LÄS MER

  4. 3. Synthesis of nanoporous Ca3Co4O9 thin films for flexible thermoelectrics

    Författare :Binbin Xin; Per Eklund; Biplab Paul; Niclas Solin; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : During energy generation, transportation and usage, large amounts of energy are lost as waste heat. With increasing energy consumption and environmental issues, exploiting this waste heat has drawn extensive attention. LÄS MER

  5. 4. GPS for Geophysics: Glacial Isostatic Adjustment and Tests of Ionospheric Models

    Författare :Sten Bergstrand; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; rheology; noise; crustal deformation; horizontal movement; time series analysis; ionosphere; GPS; NeQuick;

    Sammanfattning : This dissertation is divided into two parts that separately utilize high precision Global Positioning System (GPS) satellite observations for inferences of solid earth and ionospheric parameters.In the first part of the dissertation, solid earth movements in Sweden and Finland are observed with GPS at a precision of the order 0.1 mm/yr.

  7. 5. Thin Films and Multilayers of Yba2Cu3O7-δ and Srtio3; Growth, Characterization, And secondary Phase Formation

    Författare :Niclas Edvardsson; Michael Karkut; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Sputter-deposited thin films and multilayers of YBa2Cu3O7-δ (YBCO) and SrTi03 (STO) have been grown and studied. Microstructure in general, and formation of secondary phases, in particular, have been studied in relation to growth conditions. LÄS MER
