    • In operando neutron diffraction study of LaNdMgNi9H13 as a metal hydride battery anode 

      Nazer, N.S.; Denys, Roman Volodymyrovich; Yartys, Volodymyr; Hu, Weikang; Latroche, M.; Cuevas, F; Hauback, Bjørn; Henry, P.F.; Arnberg, Lars (Journal article; Peer reviewed, 2017-03-01)
      La2MgNi9-related alloys are superior metal hydride battery anodes as compared to the commercial AB5 alloys. Nd-substituted La2-yNdyMgNi9 intermetallics are of particular interest because of increased diffusion rate of ...

    • Revisiting the Crystal Structure of Rhombohedral Lead Metaniobate 

      Olsen, Gerhard H.; Sørby, Magnus Helgerud; Hauback, Bjørn; Selbach, Sverre Magnus; Grande, Tor (Journal article; Peer reviewed, 2014)
      Lead metaniobate (PbNb2O6) can exist both as a stable rhombohedral and a metastable orthorhombic tungsten-bronze-type polymorph. While the orthorhombic is a well-known ferroelectric material, the rhombohedral polymorph ...

    • The role of grain boundary scattering in reducing the thermal conductivity of polycrystalline XNiSn (X=Hf, Zr, Ti) half-Heusler alloys 

      Schrade, Matthias; Berland, Kristian; Eliassen, Simen Nut Hansen; Guzik, Matylda Natalia; Echevarria-Bonet, Cristina; Sørby, Magnus Helgerud; Jenus, Petra; Hauback, Bjørn; Tofan, Raluca; Gunnæs, Anette Eleonora; Persson, Clas; Løvvik, Ole Martin; Finstad, Terje (Journal article; Peer reviewed, 2017)
      Thermoelectric application of half-Heusler compounds suffers from their fairly high thermal conductivities. Insight into how effective various scattering mechanisms are in reducing the thermal conductivity of fabricated ...
