  • Thermoelectric properties of A-site deficient La-doped SrTiO3 at 100–900 °C under reducing conditions 
    Singh, Sathya Prakash; Kanas, Nikola; Desissa, Temesgen Debelo; Johnsson, Mats; Einarsrud, Mari-Ann; Norby, Truls Eivind; Wiik, Kjell (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    Lanthanum doped strontium titanate is a potential n-type thermoelectric material at moderate and high temperatures. (La0.12Sr0.88)0.95TiO3 ceramics were prepared by two different routes, conventional sintering at 1500 °C ...
  • Thermoelectric Properties of Ca3Co2−xMnxO6 (x = 0.05, 0.2, 0.5, 0.75, and 1) 
    Kanas, Nikola; Singh, Sathya Prakash; Rotan, Magnus; Desissa, Temesgen Debelo; Grande, Tor; Wiik, Kjell; Norby, Truls Eivind; Einarsrud, Mari-Ann (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    High-temperature instability of the Ca3Co4−yO9+δ and CaMnO3−δ direct p-n junction causing the formation of Ca3Co2−xMnxO6 has motivated the investigation of the thermoelectric performance of this intermediate phase. Here, ...
  • Thermoelectric properties of non-stoichiometric CaMnO3-d composites formed by redox-activated exsolution. 
    Singh, Sathya Prakash; Kanas, Nikola; Desissa, Temesgen Debelo; Einarsrud, Mari-Ann; Norby, Truls Eivind; Wiik, Kjell (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    A novel synthesis route for preparing well-defined composites based on CMO (CaMnO3) has been established taking advantage of the unique phase relations in the system Ca-Mn-O at reducing- and oxidizing atmosphere, respectively. ...
  • Visible Light Driven Photocatalytic Decolorization and Disinfection of Water Employing Reduced TiO2 Nanopowders 
    Kang, Xiaolan; Berberidou, Chrysanthi; Galeckas, Augustinas; Bazioti, Kalliopi; Sagstuen, Einar; Norby, Truls Eivind; Poulios, Ioannis; Chatzitakis, Athanasios Eleftherios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Defect-engineering of TiO2 can have a major impact on its photocatalytic properties for the degradation of persisting and non-biodegradable pollutants. Herein, a series of intrinsic and extrinsic defects are induced by ...
