Comparing laboratory and field samples of lime-cement improved Norwegian clay
Paniagua Lopez, Ana Priscilla; Falle, F. A.; Sølve, Hov; Tekseth, Kim Robert Bjørk; Mirzaei, Fazel; Breiby, Dag Werner (Journal article; Peer reviewed, 2022) -
Computational imaging of structure and liquid dynamics in porous media
Tekseth, Kim Robert Bjørk (Doctoral theses at NTNU;2024:188, Doctoral thesis, 2024)Imaging techniques, in particular computational imaging techniques utilizing computers in the image formation process, play an important role in scientific research, providing experimental support to theories and gaining ... -
High-energy X-ray Tomography for 3D Void Characterization in Au–Sn Solid-Liquid Interdiffusion (SLID) Bonds
Aasmundtveit, Knut; Tekseth, Kim Robert Bjørk; Breiby, Dag Werner; Nguyen, Hoang-Vu (Chapter; Peer reviewed, 2019)Au-Sn SLID bonding is a technique originally developed for harsh environment applications. The technology has recently shown promising results for ultrasound transducer fabrication. Characterizing the spatial and size ... -
High-resolution polarization-sensitive Fourier ptychography microscopy using a high numerical aperture dome illuminator
Gholamimayani, Mahdieh; Tekseth, Kim Robert Bjørk; Breiby, Dag Werner; Klein, Joern; Akram, Muhammad Nadeem (Peer reviewed; Journal article, 2022)Polarization-sensitive Fourier-ptychography microscopy (pFPM) allows for high resolution imaging while maintaining a large field of view, and without mechanical movements of optical-setup components. In contrast to ordinary ... -
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 ... -
Quantifying the hydroxyapatite orientation near the ossification front in a piglet femoral condyle using X-ray diffraction tensor tomography
Mürer, Fredrik Kristoffer; Chattopadhyay, Basab; Madathiparambil, Aldritt Scaria; Tekseth, Kim Robert Bjørk; Di Michel, Marco; Liebi, Marianne; Lilledahl, Magnus Borstad; Olstad, Kristin; Breiby, Dag Werner (Peer reviewed; Journal article, 2021)While a detailed knowledge of the hierarchical structure and morphology of the extracellular matrix is considered crucial for understanding the physiological and mechanical properties of bone and cartilage, the orientation ... -
Quantitative Polychromatic X-Ray Computed Tomography - Experiments and Simulations
Tekseth, Kim Robert Bjørk (Master thesis, 2018)X-ray Computed Tomography (CT) is an extensively used technique conventionally utilizing either absorption-contrast or phase-contrast to non-destructively image the internal structures of objects. While CT instruments using ... -
A technique for in situ X-ray computed tomography of deformation-induced cavitation in thermoplastics
Olufsen, Sindre Nordmark; Tekseth, Kim Robert Bjørk; Breiby, Dag Werner; Clausen, Arild Holm; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2020)Deformation-induced cavitation influences the mechanical response of polymeric materials, but acquiring in situ measurements of the spatial evolution of cavities has typically necessitated the use of synchrotron radiation ...
