• Atomic Structure of Hardening Precipitates in Al-Mg-Si Alloys: Influence of Minor Additions of Cu and Zn 

      Bartawi, Emad H.; Marioara, Calin Daniel; Shaban, Ghada; hatzoglou, constantinos; Holmestad, Randi; Ambat, Rajan (Peer reviewed; Journal article, 2023)
      Shifting toward sustainability and low carbon emission necessitates recycling. Aluminum alloys can be recycled from postconsumer scrap with approximately 5% of the energy needed to produce the same amount of primary alloys. ...
    • Dislocation-Driven Relaxation Processes at the Conical to Helical Phase Transition in FeGe 

      Schoenherr, Peggy; Stepanova, Mariia; Lysne, Erik Nikolai; Kanazawa, Naoya; Tokura, Yoshinori; Bergman, Anders; Meier, Dennis Gerhard (Journal article, 2021)
      The formation of topological spin textures at the nanoscale has a significant impact on the long-range order and dynamical response of magnetic materials. We study the relaxation mechanisms at the conical-to-helical phase ...
    • High interfacial charge storage capability of carbonaceous cathodes for Mg batteries 

      Wang, Lu; Jiang, Bo; Vullum, Per Erik; Svensson, Ann Mari; Erbe, Andreas; Selbach, Sverre Magnus; Xu, Huailiang; Vullum-Bruer, Fride (Journal article; Peer reviewed, 2018)
      A rechargeable Mg battery where the capacity mainly originates from reversible reactions occurring at the electrode/electrolyte interface efficiently avoids the challenge of sluggish Mg intercalation encountered in ...
    • Oxygen Incorporation and Release in Metastable Bixbyite V2O3 Nanocrystals 

      Bergerud, Amy; Selbach, Sverre Magnus; Milliron, Delia J. (Journal article, 2016)
      A new, metastable polymorph of V2O3 with a bixbyite structure was recently stabilized in colloidal nanocrystal form. Here, we report the reversible incorporation of oxygen in this material, which can be controlled by varying ...
    • Stoichiometry-Controlled Reversible Lithiation Capacity in Nanostructured Silicon Nitrides Enabled by in Situ Conversion Reaction 

      Ulvestad, Asbjørn; Skare, Marte Orderud; Foss, Carl Erik Lie; Krogsæter, Henrik; Reichstein, Jakob; Preston, Thomas J.; Mæhlen, Jan Petter; Andersen, Hanne Flåten; Koposov, Alexey (Peer reviewed; Journal article, 2021)
      In modern Li-based batteries, alloying anode materials have the potential to drastically improve the volumetric and specific energy storage capacity. For the past decade silicon has been viewed as a “Holy Grail” among these ...
