    • Closing of Micro-cavities in Well Cement upon Exposure to CO2 Brine 

      Chavez Panduro, Elvia Anabela; Torsæter, Malin; Gawel, Kamila; Bjørge, Ruben; Gibaud, Alain; Yang, Yi; Sørensen, Henning; Frykman, Peter; Kjøller, Claus; Breiby, Dag Werner (Journal article; Peer reviewed, 2017)
      Long-lasting cement plugging of wells is crucial for successful CO2 storage in underground reservoirs. It requires a profoundly improved understanding of the behavior of fractured cement under realistic subsurface conditions ...

    • Colloidal crystals as templates for light harvesting structures in solar cells 

      Haugan, Einar; Granlund, Håvard; Gjessing, Jo; Marstein, Erik Stensrud (Journal article; Peer reviewed, 2011)
      Monolayer colloidal crystals are formed using silica- and polystyrene beads and used as etch masks for the formation of regular, _m period hexagonal arrays of indentations in a silicon wafer. Such patterns can be used as ...

    • Modelling of heat transport in two-phase flow and of mass transfer between phases using the level-set method 

      Gjennestad, Magnus Aashammer; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2015)
      We describe mathematical models for heat transport and for mass transfer between phases due to vaporization and condensation. These models have been implemented in a framework for detailed two-phase flow calculations based ...

    • Synchrotron Study of Cement Hydration: Towards Computed Tomography Analysis of Interfacial Transition Zone 

      Lavrov, Alexandre; Chavez Panduro, Elvia Anabela; Torsæter, Malin (Journal article; Peer reviewed, 2017)
      The quality of bonding between cement and steel in wells is controlled by the interfacial transition zone (ITZ). Micro-computed X-ray tomography (μ-CT) imaging with synchrotron radiation was used in the current paper to ...
