Liu, Xin; Bjørheim, Tor Svendsen; Vines, Lasse; Fjellvåg, Øystein; Granerød, Cecilie Skjold; Prytz, Øystein; Yamamoto, Takafumi; Kageyama, Hiroshi; Norby, Truls Eivind; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Mixed oxide hydride anion systems constitute a novel class of materials exhibiting intriguing properties such as solid-state hydride ion conduction and fast anion exchange. In this contribution we derive the kinetics of ...

Desissa, Temesgen D.; Haugsrud, Reidar; Wiik, Kjell; Norby, Truls Eivind (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We herein report inter-diffusion across the interface between p-type Ni0.98Li0.02O and n-type Zn0.98Al0.02O for various applications including p-n-heterojunction diodes and oxide thermoelectrics. Diffusion couples were ...

Stefan, Elena; Stange, Marit Synnøve Sæverud; Denonville, Christelle; Larring, Yngve; Hildenbrand, Nicolas; Norby, Truls Eivind; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Planar metal-supported cell designs provide cost-effective scaling-up of solid oxide fuel cells and electrolysers. Here, we report on the fabrication of a BaZr0.85Y0.15O3−δ–NiO (BZY15–NiO) composite electrode and ...

Bjørheim, Tor Svendsen; Løken, Andreas; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In this contribution, we determine the compositional dependence of the chemical expansion and entropy of hydration of the proton conducting perovskites BaZrO3, BaSnO3, BaCeO3, and SrZrO3 by first principles phonon calculations. ...

Løken, Andreas; Bjørheim, Tor Svendsen; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)The choice of acceptor has been demonstrated to result in distinctly different hydration properties in proton conducting perovskites such as BaZrO3 and BaCeO3 and may as such have significant implications for their proton ...

Løken, Andreas; Haugsrud, Reidar; Bjørheim, Tor Svendsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Differentiating chemical and thermal expansion is virtually impossible to achieve experimentally. While thermal expansion stems from a softening of the phonon spectra, chemical expansion depends on the chemical composition ...
