• CO desorption from nickel-decorated muscovite mica 

      Hunvik, Kristoffer William Bø; Støvneng, Anna; Pacáková, Barbara; Raaen, Steinar (Journal article; Peer reviewed, 2019)
      Adsorption and desorption of CO from Ni nanostructures deposited on muscovite mica substrates have been studied by TPD and characterized by XPS and AFM. In agreement with previous reports it is found that CO does not adsorb ...
    • CO2 adsorption on pure and oxidised Ni nano-structures deposited on mica surfaces 

      Hunvik, Kristoffer William Bø; Pacáková, Barbara; Raaen, Steinar (Peer reviewed; Journal article, 2020)
      Adsorption and desorption of CO2 on metallic and oxidised Ni nano-structures supported on mica (muscovite) substrates have been studied by temperature-programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS) and ...
    • Introducing Well-Defined Nanowrinkles in CVD Grown Graphene 

      Verhagen, Tim; Pacáková, Barbara; Kalbac, Martin; Vejpravova, Jana (Journal article; Peer reviewed, 2019)
      The control of graphene’s topography at the nanoscale level opens up the possibility to greatly improve the surface functionalization, change the doping level or create nanoscale reservoirs. However, the ability to control ...
    • 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 ...
    • Sample cell for studying liquid interfaces with an in situ electric field using X-ray reflectivity and application to clay particles at oil-oil interfaces 

      Larsen, Simon R.; Hansteen, Marie; Pacáková, Barbara; Theodor, Keld; Arnold, Thomas; Rennie, Adrian R.; Helgesen, Geir; Knudsen, Kenneth Dahl; Bordallo, Heloisa N.; Fossum, Jon Otto (Journal article; Peer reviewed, 2018)
      Commissioning results of a liquid sample cell for X-ray reflectivity studies with an in situ applied electrical field are presented. The cell consists of a Plexiglas container with lateral Kapton windows for air–liquid and ...
    • Superlattice in collapsed graphene wrinkles 

      Verhagen, Tim; Pacáková, Barbara; Bousa, Milan; Hubner, Uwe; Kalbac, Martin; Vejpravova, Jana; Frank, Otakar (Journal article; Peer reviewed, 2019)
      Topographic corrugations, such as wrinkles, are known to introduce diverse physical phenomena that can significantly modify the electrical, optical and chemical properties of two-dimensional materials. This range of assets ...
