    • Numerical integrators for Lagrangian oceanography 

      Nordam, Tor; Duran, Rodrigo (Peer reviewed; Journal article, 2020)
      A common task in Lagrangian oceanography is to calculate a large number of drifter trajectories from a velocity field pre-calculated with an ocean model. Mathematically, this is simply numerical integration of an Ordinary ...

    • Real Time 3D Observations of Portland Cement Carbonation at CO2 Storage Conditions 

      Chavez Panduro, Elvia Anabela; Cordonnier, Benoit; Gawel, Kamila; Børve, Ingrid; Iyer, Jaisree; Carroll, Susan; Michels, Leander; Rogowska, Melania; McBeck, Jessica Ann; Sørensen, Henning; Walsh, Stuart; Renard, Francois; Gibaud, Alain; Torsæter, Malin; Breiby, Dag Werner (Peer reviewed; Journal article, 2020)
      Depleted oil reservoirs are considered a viable solution to the global challenge of CO2 storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO2. Under reservoir conditions, ...

    • Reversed Hysteresis during CO Oxidation over Pd75Ag25(100) 

      Fernandes, Vasco Rafael P; Van der Bossche, Maxime; Knudsen, Jan; Farstad, Mari Helene; Gustafson, Johan; Venvik, Hilde Johnsen; Grönbeck, Henrik; Borg, Anne (Journal article; Peer reviewed, 2016)
      CO oxidation over Pd(100) and Pd75Ag25(100) has been investigated by a combination of near-ambient-pressure X-ray photoelectron spectroscopy, quadrupole mass spectrometry, density functional theory calculations, and ...

    • Scattering amplitudes of massive Nambu-Goldstone bosons 

      Brauner, Tomas; Jakobsen, Martin Fonnum (Journal article; Peer reviewed, 2018)
      Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ...
