3D Maps of Mineral Composition and Hydroxyapatite Orientation in Fossil Bone Samples Obtained by X-ray Diffraction Computed Tomography
(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 ... -
3D modelling of β'' in Al-Mg-Si: towards an atomistic level ab initio based examination of a full precipitate enclosed in a host lattice
(Journal article, 2014)We extend a first principles based hierarchical multi-scale model scheme for describing a fully coherent precipitate in a host lattice to 3D simulations. As our test system, the needle-shaped main hardening Al–Mg–Si alloy ... -
3D non-isothermal phase-field simulation of microstructure evolution during selective laser sintering
(Journal article; Peer reviewed, 2019)During selective laser sintering (SLS), the microstructure evolution and local temperature variation interact mutually. Application of conventional isothermal sintering model is thereby insufficient to describe SLS. In ... -
3D orientational imaging of gallbladder stones
(Bachelor thesis, 2024)X-ray Diffraction Tensor Tomography is an emerging imaging technique to study the mineralogy and orientation of crystallites at a microscale level. In the work presented in this thesis, we have tested an algorithm developed ... -
3D TEM characterization of silver implanted silicon for intermediate band solar cells
(Master thesis, 2017)As the need for renewable and sustainable energy sources are growing solar cells are turning into one of the most affordable and widely adopted solutions for renewable electricity production. This is driven by a steady ... -
3D-EPI with parallel imaging acceleration along two Axis: Evaluated with Phantom Study and BOLD fMRI
(Master thesis, 2013)The function of the human brain has for many years been an intriguing field of research, and has led to the discovery of functional MRI (fMRI). fMRI is dependent on high spatial and temporal resolution to acquire detailed ... -
