    • Collembola cuticles and the three-phase line tension 

      Gundersen, Håkon A Holm; Leinaas, Hans Petter; Thaulow, Christian (Journal article; Peer reviewed, 2017)
      The cuticles of most springtails (Collembola) are superhydrophobic, but the mechanism has not been described in detail. Previous studies have suggested that overhanging surface structures play an important role, but such ...

    • Diatoms in new design 

      Morland, Markus (Master thesis, 2014)
      The first part of this thesis is a literature study into the applications of diatom frustules. The second part is FE-analysis of micromechanical testing of diatom frustules undertaken at NTNU. The models are based on ...

    • Diatoms Investigated by Atomic Force Microscopy 

      Svendsgaard, Torstein (Master thesis, 2015)
      Diatoms are microscopic algae which have a complex outer cell wall(frustule) made up by silicon dioxide and organic proteins, collectively called biosilica. The mechanical properties of the diatom frustule have been a ...

    • Finite Element Modelling of Weldments 

      Kolstad, Gaute Thorson (Master thesis, 2012)
      Brittle fracture is a large problem for steel structures in the arctic region. It is thus important to qualify materials and welds so they do not behave in a brittle manner. Since fracture testing of the heat affected zone ...

    • GROWTH AND PROPERTIES OF CARBON NANOTUBES 

      Nordheim, Karl Erik (Master thesis, 2012)
      An experimental study of Carbon Nanotube (CNT) growth has been performed by using radio frequency plasma enhanced chemical vapour deposition with methane (CH4) as the hydrocarbon source. The experimental results have been ...

    • In-situ Compession Testing of Nanosized Pillars 

      Hagen, Anette Brocks (Master thesis, 2014)
      Applications of nanomechanical testing methods have become increasingly important in all fields of material research. There is a significant interest in obtaining information about material features at small scales, in ...

    • IN-SITU FRACTURE MECHANICAL TESTING OF MICROSIZED CANTILEVERS 

      Greina, Kristine (Master thesis, 2014)
      The arctic is an appealing new ventures area for the oil and gas industry. However the climate is extremely demanding, and more technically challenging than any other environment. With design temperatures down to -60°C the ...
