    • 3D Maps of Mineral Composition and Hydroxyapatite Orientation in Fossil Bone Samples Obtained by X-ray Diffraction Computed Tomography 

      Mürer, Fredrik Kristoffer; Sanchez, Sophie; Alvarez-Murga, Michelle; Di Michiel, Marco; Pfeiffer, Franz; Bech, Martin; Breiby, Dag Werner (Journal article; Peer reviewed, 2018)
      Whether hydroxyapatite (HA) orientation in fossilised bone samples can be non-destructively retrieved and used to determine the arrangement of the bone matrix and the location of muscle attachments (entheses), is a question ...

    • Correcting lateral chromatic aberrations in non-monochromatic X-ray microscopy 

      Falch, Ken Vidar; Detlefs, Carsten; Di Michiel, Marco; Snigireva, Irina; Snigirev, Anatoly; Mathiesen, Ragnvald (Journal article; Peer reviewed, 2016)
      Lateral chromatic aberration in microscopy based on refractive optics may be reduced significantly by adjustments to the illumination scheme. By taking advantage of a broadened bandwidth illumination, the proposed scheme ...

    • In situ hard X-ray transmission microscopy for material science 

      Falch, Ken Vidar; Casari, Daniele; Di Michiel, Marco; Detlefs, Carsten; Snigirev, Anatoly; Snigireva, Irina; Honkimäki, Veijo; Mathiesen, Ragnvald (Journal article; Peer reviewed, 2017)
      Hard X-ray transmission microscopy based on refractive X-ray optics can be employed as a tool in material science to investigate buried-in microstructures in two or three dimensions with spatial resolution approaching 100 ...

    • Orientational mapping of minerals in Pierre shale using X-ray diffraction tensor tomography 

      Mürer, Fredrik Kristoffer; Madathiparambil, Aldritt Scaria; Tekseth, Kim Robert Bjørk; Di Michiel, Marco; Cerasi, Pierre; Chattopadhyay, Basab; Breiby, Dag Werner (Peer reviewed; Journal article, 2021)
      Shales have a complex mineralogy with structural features spanning several length scales, making them notoriously difficult to fully understand. Conventional attenuation-based X-ray computed tomography (CT) measures density ...

    • Zernike phase contrast in high-energy x-ray transmission microscopy based on refractive optics 

      Falch, Ken Vidar; Lyubormiskiy, Mikhail; Casari, Daniele; Snigirev, Anatoly; Snigireva, Irina; Detlefs, Carsten; Di Michiel, Marco; Lyatun, Ivan; Mathiesen, Ragnvald (Journal article; Peer reviewed, 2018)
      The current work represents the first implementation of Zernike phase contrast for compound refractive lens based x-ray microscopy, and also the first successful Zernike phase contrast experiment at photon energies above ...
