    • In situ coherent X-ray diffraction imaging of radiation-induced mass loss in metal-polymer composite spheres 

      Skjønsfjell, Eirik Torbjørn Bakken; Chushkin, Yuriy; Zontone, Federico; Breiby, Dag Werner (Peer reviewed; Journal article, 2018)
      A major limitation to the use of coherent X-ray diffraction imaging (CXDI) for imaging soft materials like polymers and biological tissue is that the radiation can cause extensive damage to the sample under investigation. ...

    • Mapping Orientation Distribution of Talc Particles in Polypropylene by Small-Angle X-ray Scattering Tomography 

      Skjønsfjell, Eirik Torbjørn Bakken (Master thesis, 2013)
      Small-angle X-ray scattering tomography has for the first time been used toinvestigate the spatially resolved orientation distribution of talc particles in asample of injection molded isotactic polypropylene, where the ...

    • Quantitative 3D Imaging and Metrology Using Coherent X-ray Scattering 

      Skjønsfjell, Eirik Torbjørn Bakken (Doctoral theses at NTNU;2017:300, Doctoral thesis, 2017)
      This thesis has focused on exploring methods of using coherent X-ray scattering at synchrotron sources. New imaging techniques using coherent X-ray scattering have been investigated, and it has been discussed how limitations ...

    • 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 ...

    • X-ray nanoscopy of a bulk heterojunction 

      Patil, Nilesh; Skjønsfjell, Eirik Torbjørn Bakken; Van den Brande, Niko; Chavez Panduro, Elvia Anabela; Claessens, Raf; Guizar-Sicairos, Manuel; Van Mele, Bruno; Breiby, Dag Werner (Journal article; Peer reviewed, 2016)
      Optimizing the morphology of bulk heterojunctions is known to significantly improve the photovoltaic performance of organic solar cells, but available quantitative imaging techniques are few and have severe limitations. ...
