Salt clogging during supercritical CO2 injection into a downscaled borehole model
(Journal article; Peer reviewed, 2019)Injection of CO2 into saline storage aquifers is often accompanied by drying of the formation water and salt precipitation. Subsequent salt clogging of a well bore and the near wellbore rock matrix may lead to injectivity ... -

Sample cell for studying liquid interfaces with an in situ electric field using X-ray reflectivity and application to clay particles at oil-oil interfaces
(Journal article; Peer reviewed, 2018)Commissioning results of a liquid sample cell for X-ray reflectivity studies with an in situ applied electrical field are presented. The cell consists of a Plexiglas container with lateral Kapton windows for air–liquid and ... -
Satellite mapping of particle precipitation effects on the Antarctic middle atmosphere
(Master thesis, 2011)The aim of this thesis is to study the effects of particle precipitation on O3 and OH caused by a moderate geomagnetic storm in late July 2009. The basis is data retrieved over Antarctica from the Odin and Aura satellites ... -
Satellite peaks in the scattering of light from the two-dimensional randomly rough surface of a dielectric film on a planar metal surface
(Journal article; Peer reviewed, 2012)A nonperturbative, purely numerical, solution of the reduced Rayleigh equation for the scattering of p- and s-polarized light from a dielectric film with a two-dimensional randomly rough surface deposited on a planar ... -
Scalar wave scattering from two-dimensional, randomly rough surfaces
(Master thesis, 2011)We study scalar waves scattered from self-affine and Gaussian correlated surfaces. The simulations are performed using rigorous simulation of the integral equations derived from the Helmholtz equation, describing a scalar ... -
Scanning Precession Electron Diffraction Study of 2xxx Series Aluminium Alloys Exhibiting Several Coexisting Strengthening Phases
(Master thesis, 2016)Throughout this thesis, scanning precession electron diffraction is applied to heat-treated Al-Cu-Li and Al-Mg-Cu-Ag alloys, shedding light on the distribution of phases present and the complex interplay between these ... -
Scanning Precession Electron Diffraction Study of Hybrid Precipitates in a 6xxx Series Aluminium Alloy
(Journal article; Peer reviewed, 2017)Obtaining reliable and statistical assessment of nanoscale precipitates to link the microstructure with material properties is a primary objective of transmission electron microscopy (TEM) studies of agehardenable aluminium ... -

Scanning transmission electron microscopy studies of precipitation in Al-Mg-Ge alloys
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:234, Doctoral thesis, 2011)Precipitation in three Al-Mg-Ge(-Si-Cu) alloys has been investigated using transmission electron microscopy. The alloy compositions were chosen to be similar to previously studied Al-Mg-Si(-Cu) alloys to facilitate direct ... -
Scanning tunneling microscopy based point-contact measurements of nanoscale magnetic systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:178, Doctoral thesis, 2010)In this thesis, the method of scanning tunneling microscopy (STM) based pointcontacts is presented together with measurements on nanonscale magnetic systems. The method allows point-contacts to be positioned with nm lateral ... -
Scanning X-ray ScatteringStudies of Mechanically Processed Polymers
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:324, Doctoral thesis, 2013)Employing raster-scanning small- and wide-angle X-ray scattering (SAXS and WAXS), morphological variations in weakly scattering polymers have been mapped. These techniques inherently yield information on multiple length ... -
(Scanning) Transmission Electron Microscopy Studies of Grain Boundary Segregation relevant to Intergranular Corrosion in Al-Mg-Si-Cu Alloys
(Doctoral thesis at NTNU;2015:23, Doctoral thesis, 2015)The effect of the alloy composition on the susceptibility to intergranular corrosion in Al-Mg-Si-Cu alloys has been investigated by Transmission Electron Microscopy. The main focus of this thesis has been the effect of ... -
Scattering amplitudes of massive Nambu-Goldstone bosons
(Journal article; Peer reviewed, 2018)Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ... -
Scattering of Electromagnetic Waves from Randomly Rough Surfaces with Skewed Height Distributions
(Master thesis, 2014)Research on the scattering of electromagnetic waves from rough surfaces has greatly advanced in the past decades through the access to rigorous numerical simulations. However, most of the research has focused on surfaces ... -

Scattering theory of transport through disordered magnets
(Journal article; Peer reviewed, 2019)We present a scattering theory of transport through noncollinear disordered magnetic insulators. For concreteness, we study and compare the random field model (RFM) and the random anisotropy model (RAM). The RFM and RAM ... -
Schrödinger-Poisson and nonequilibrium Green's function methods applied to layered semiconductor devices
