    • Domain structures in PbTiO3 thin films 

      Fløystad, Jostein Bø (Master thesis, 2010)
      We have studied thin films (27 and 50 unit cells) of ferroelectric PbTiO3 by acquiring reciprocal space maps using wide-angle x-ray scattering. Diffuse satelites were found around the PbTiO3 Bragg peaks, consistent with a ...

    • GPU-Accelerated Visualization of Scattered Point Data 

      Falch, Thomas Løfsgaard; Fløystad, Jostein Bø; Breiby, Dag Werner; Elster, Anne C. (Journal article; Peer reviewed, 2013)
      As data sets continue to grow in size, visualization has become a vitally important tool for extracting meaningful knowledge. Scattered point data, which are unordered sets of point coordinates with associated measured ...

    • In situ hard X-ray ptychographic imaging for materials science 

      Fløystad, Jostein Bø (Doktoravhandlinger ved NTNU, 1503-8181; 2014:244, Doctoral thesis, 2014)
      With the ability to control the structure of multiphase materials for applications on the nano- and mesoscale, methods for imaging these materials are becoming increasingly important. Especially techniques able to image ...

    • Partielle utladninger i kryssbundet polyetylen med forurensninger 

      Smisethjell, Heidi (Master thesis, 2016)
      Partielle utladninger (PD) er kjent for å være en av de viktigste feil- og aldringsmekanismene i PEX-kabler. Renhet i isolasjonen blir derfor ansett som en viktig parameter da forurensninger, både organiske og uorganiske, ...

    • Quantitative 3D X-ray Imaging of Densification, Delamination and Fracture in a Micro-Composite under Compression 

      Fløystad, Jostein Bø; Skjønsfjell, Eirik Torbjørn Bakken; Guizar-Sicairos, Manuel; Høydalsvik, Kristin; He, Jianying; Andreasen, Jens Wenzel; Zhang, Zhiliang; Breiby, Dag Werner (Journal article; Peer reviewed, 2015)
      Phase-contrast three-dimensional tomograms showing in unprecedented detail the mechanical response of a micro-composite subjected to a mechanical compression test are reported. The X-ray ptychography images reveal the ...
