Chemical stability of Ca3Co4−xO9+δ/CaMnO3−δ p–n junction for oxide-based thermoelectric generators
Gunnæs, Anette Eleonora; Tofan, Raluca; Berland, Kristian; Gorantla, Sandeep Madhukar; Storaas, Thomas Aarflot; Desissa, Temesgen Debelo; Schrade, Matthias; Persson, Clas; Einarsrud, Mari-Ann; Wiik, Kjell; Norby, Truls Eivind; Kanas, Nikola (Peer reviewed; Journal article, 2020)An all-oxide thermoelectric generator for high-temperature operation depends on a low electrical resistance of the direct p–n junction. Ca3Co4−xO9+δ and CaMnO3−δ exhibit p-type and n-type electronic conductivity, respectively, ... -
Dipentamethylene thiuram tetrasulfide-based cathodes for rechargeable magnesium batteries
Kaland, Henning; Hadler-Jacobsen, Jacob; Fagerli, Frode Håskjold; Wagner, Nils Peter; Schnell, Sondre Kvalvåg; Wiik, Kjell (Peer reviewed; Journal article, 2020)Rechargeable Mg batteries (RMBs) represent a possible route for low-cost energy storage applications, but they are lacking a satisfactory cathode material. Conventional sulfur (S8) cathodes have shown promise, yet they ... -
Hot corrosion of Gd2Zr2O7, Gd2Zr2O7/YbSZ, YSZ+Gd2Zr2O7/YbSZ, and YSZ thermal barrier coatings exposed to Na2SO4+V2O5.
Tabeshfar, Mohadese; Salehi, Mehdi; Dini, Ghasem; Dahl, Paul Inge; Einarsrud, Mari-Ann; Wiik, Kjell (Peer reviewed; Journal article, 2020)Gd2Zr2O7 ceramic is considered as a potential candidate for thermal barrier coatings. Here we present hot corrosion behavior of single layer Gd2Zr2O7 (GZO), Gd2Zr2O7 + 50 wt% YbSZ (GZO/YbSZ), YSZ and double-layer ... -
Manufacturing of perovskite oxygen carriers by spray granulation for chemical looping combustion
Thoréton, Vincent; Darell, Ove; Spjelkavik, Aud I.; Sunding, Martin Fleissner; Mokkelbost, Tommy; Pishahang, Mehdi; Wiik, Kjell; Larring, Yngve (Journal article; Peer reviewed, 2017) -
Microstructural Stability of Tailored CaMn0.875−xFexTi0.125O3−δ Perovskite Oxygen Carrier Materials for Chemical Looping Combustion
Thoréton, Vincent; Pishahang, Mehdi; Mokkelbost, Tommy; Wiik, Kjell; Larring, Yngve (Journal article; Peer reviewed, 2017) -
Removing fluoride-terminations from multilayered V2CTx MXene by gas hydrolyzation
Fagerli, Frode Håskjold; Wang, Zhaohui; Grande, Tor; Kaland, Henning; Selbach, Sverre Magnus; Wagner, Nils Peter; Wiik, Kjell (Peer reviewed; Journal article, 2022)Two-dimensional MXenes have shown great promise for many different applications, but in order to fully utilize their potential, control of their termination groups is essential. Here we demonstrate hydrolyzation with a ... -
Structure, electrical conductivity and oxygen transport properties of perovskite-type oxides CaMn1−x−yTixFeyO3−δ
Ruhl, Rian; Song, Jia; Thoréton, Vincent; Singh, Sathya Prakash; Wiik, Kjell; Larring, Yngve; Bouwmeester, Henny J. M. (Journal article; Peer reviewed, 2019)Calcium manganite-based perovskite-type oxides hold promise for application in chemical looping combustion processes and oxygen transport membranes. In this study, we have investigated the structure, electrical conductivity ...
