    • 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 ...

    • Influence of CO2 on Nanoconfined Water in a Clay Mineral 

      Hunvik, Kristoffer William Bø; Lima, Rodrigo José Da Silva; Kirch, Alexsandro; Loch, Patrick; Monceyron Røren, Paul; Hoffmann Petersen, Martin; Rudić, Svemir; García Sakai, Victoria; Knudsen, Kenneth Dahl; Rodrigues Miranda, Caetano; Breu, Josef; Fossum, Jon Otto; Bordallo, Heloisa N. (Peer reviewed; Journal article, 2022)
      Developing new technologies for carbon sequestration and long-term carbon storage is important. Clay minerals are interesting in this context as they are low-cost, naturally abundant, can adsorb considerable amounts of ...

    • 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 ...

    • Large bandgap insulating superior clay nanosheets 

      Pacáková, Barbara; Vullum, Per Erik; Kirch, Alexsandro; Breu, Josef; Miranda, Caetano Rodrigues; Fossum, Jon Otto (Journal article; Peer reviewed, 2022)
      One can find conductive, semiconducting, and insulating single nanosheets with unique electronic properties that are tied to their two-dimensional (2D) structure. Here, we report on wide-bandgap 2D insulator nanosheets ...
