    • CO2 Adsorption Enhanced by Tuning the Layer Charge in a Clay Mineral 

      Hunvik, Kristoffer William Bø; Loch, Patrick; Wallacher, Dirk; Kirch, Alexsandro; Cavalcanti, Leide Passos; Rieß, Martin; Daab, Matthias; Josvanger, Vegard; Grätz, Sven; Yokaichiya, Fabiano; Knudsen, Kenneth Dahl; Miranda, Caetano Rodrigues; Breu, Josef; Fossum, Jon Otto (Peer reviewed; Journal article, 2021)
      Due to the compact two-dimensional interlayer pore space and the high density of interlayer molecular adsorption sites, clay minerals are competitive adsorption materials for carbon dioxide capture. We demonstrate that ...

    • Intercalation of CO2 Selected by Type of Interlayer Cation in Dried Synthetic Hectorite 

      Hunvik, Kristoffer William Bø; Seljelid, Konstanse Kvalem; Wallacher, Dirk; Kirch, Alexsandro; Cavalcanti, Leide Passos; Loch, Patrick; Røren, Paul Monceyron; Michels-Brito, Paulo Henrique; Droppa-Jr, Roosevelt; Knudsen, Kenneth Dahl; Miranda, Caetano Rodrigues; Breu, Josef; Fossum, Jon Otto (Peer reviewed; Journal article, 2023)
      Clay minerals are abundant in caprock formations for anthropogenic storage sites for CO2, and they are potential capture materials for CO2 postcombustion sequestration. We investigate the response to CO2 exposure of dried ...

    • Oxygen-Controlled Phase Segregation in Poly(N-isopropylacrylamide)/Laponite Nanocomposite Hydrogels 

      Mauroy, Henrik; Rozynek, Zbigniew; Plivelic, Tomás S.; Fossum, Jon Otto; Helgesen, Geir; Knudsen, Kenneth (Journal article; Peer reviewed, 2013)

    • Thermodynamic stability of volatile droplets and thin films governed by the disjoining pressure in open and closed containers 

      Gjennestad, Magnus Aashammer; Wilhelmsen, Øivind (Peer reviewed; Journal article, 2020)
      Distributed thin films of water and their coexistence with droplets are investigated using a capillary description based on a thermodynamic fundamental relation for the film Helmholtz energy, derived from disjoining pressure ...

    • X-ray Studies of Carbon Dioxide Intercalation in Na-Fluorohectorite Clay at Near-Ambient Conditions 

      Hemmen, Henrik; Rolseth, Erlend G.; Fonseca, Davi de Miranda; Hansen, Elisabeth Lindbo; Fossum, Jon Otto; Plivelic, T (Journal article, 2012)
      We show experimentally that gaseous CO2 intercalates into the interlayer space of the synthetic smectite clay Na-fluorohectorite at conditions not too far from ambient. The mean interlayer repetition distance of the clay ...
