• Swelling transition of a clay induced by heating 

      Hansen, Elisabeth Lindbo; Hemmen, Henrik; Fonseca, Davi de Miranda; Coutant, C.; Knudsen, Kenneth; Plivelic, T; Bonn, D; Fossum, Jon Otto (Journal article; Peer reviewed, 2012)
      Clays are of paramount importance for soil stability, but also in applications ranging from oil recovery to composites and hydrogels. Generically, clays are divided into two subclasses: macroscopically swelling, ‘active’ ...
    • 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 ...
