Non-equilibrium quantum effects in hybrid structures of ferromagnets and superconductors
(Master thesis, 2016)The quasiclassical theory of superconductivity is applied to diffusive nanowires connecting normal-metal and superconducting bulk materials. The diffusion equations for ferromagnetic junctions with spin-orbit coupling are ... -
Two Dimensional Fiber Bundle Bridge Model
(Master thesis, 2016)The two dimensional fiber bundle bridge model is introduced, derived and studied for an uniform threshold distribution. The model is independent of history and has an adjustable effective range of interaction, which is ... -
Prediction of Protein Function using semantic Fingerprints - Multivariate Data Classification by Artificial Neural Networks involving dimensional Reduction
(Master thesis, 2016)In many fields of today's scientific research the amount of knowledge is far smaller than the amount of accessible data and often too limited to make meaningful analyses and draw reasonable conclusions. Hence, statistical ... -
Precipitation in an Al-Mg-Cu alloy and the effect of a low amount of Ag
(Journal article, 2016)Two high-purity aluminium alloys based on composition Al–3.0Mg–1.0Cu (wt%), one with added 0.4 wt% Ag, were compared up to 11 days ageing at 443 K by means of transmission electron microscopy and hardness measurements. The ... -
Directionality and column arrangement principles of precipitates in Al-Mg-Si-(Cu) and Al-Mg-Cu linked to line defect in Al
(Journal article, 2016)In the structures of all metastable precipitates in Al-Mg-Cu and Al-Mg-Si alloys, we find that column surrounding of an element column in the needle/lath direction order according to simple principles. Advanced transmission ... -
Monte Carlo Simulation of Photoconductive Terahertz Sources in Mercury Cadmium Telluride
(Master thesis, 2016)In this master's thesis we explore the physics of a photoconductive terahertz emitter and diverse methods to increase its power emission. A way to simulate it via a Monte Carlo first principle simulator is presented, taking ... -
A Model for the Mixing of Black Carbon Aerosols and Mineral Dust Particles in the Atmosphere
(Master thesis, 2016)The process when freshly emitted black carbon particles are forming clusters and the mixing of these black carbon clusters and mineral dust particles has been simulated for a two-dimensional system. This has been done by ... -
Optimization, Cellular Uptake and Cytotoxicity of Lipid Nanoparticles
(Master thesis, 2016)Chemotherapy can potentially be greatly improved by using nanoparticles as drug carriers to deliver chemotherapeutic drugs specifically to cancer cells. Lipid nanoparticles can encapsulate hydrophobic drugs that have low ... -
Phenomenology of current-induced skyrmion motion in antiferromagnets
(Journal article; Peer reviewed, 2016)We study current-driven skyrmion motion in uniaxial thin film antiferromagnets in the presence of the Dzyaloshinskii–Moriya interactions and in an external magnetic field. We phenomenologically include relaxation and ... -
Quantitative comparison of PET performance-Siemens Biograph mCT and mMR
(Peer reviewed; Journal article, 2016)Background: Integrated clinical whole-body PET/MR systems were introduced in2010. In order to bring this technology into clinical usage, it is of great importance to compare the performance with the well-established PET/CT. ... -
Microscale tools for the development of bacterial microarrays
(Doctoral thesis at NTNU;2016:61, Doctoral thesis, 2016)Heterogeneity within bacterial populations is a phenomenon that has gained much interest over the last decades. It has been shown that even isogeneous colonies under homogeneous conditions can display different phenotypes. ... -
Numerical studies of the scattering of light from a two-dimensional randomly rough interface between two dielectric media
(Journal article; Peer reviewed, 2016)The scattering of polarized light incident from one dielectric medium on its two-dimensional randomly rough interface with a second dielectric medium is studied. A reduced Rayleigh equation for the scattering amplitudes ... -
Spin-valley locking in the normal state of a transition-metal dichalcogenide superconductor
(Peer reviewed; Journal article, 2016)Metallic transition-metal dichalcogenides (TMDCs) are benchmark systems for studying and controlling intertwined electronic orders in solids, with superconductivity developing from a charge-density wave state. The interplay ... -
The Lattice Boltzmann Method for Steady State Sediment Transport.
(Master thesis, 2016)Simulating water behaviour in coastal areas is an important tool when predicting sedimentary processes over geological time. We implement a general lattice Boltzmann model for shallow water flow, that can handle having ... -
Rayleigh and Wood anomalies in the diffraction of acoustic waves from the periodically corrugated surface of an elastic medium
(Journal article; Peer reviewed, 2016)By the use of the Rayleigh method we have calculated the angular dependence of the reflectivity and the efficiencies of several other diffracted orders when the periodically corrugated surface of an isotropic elastic medium ... -
Backscattering in helical edge states from a magnetic impurity and Rashba disorder
(Journal article; Peer reviewed, 2016)Transport by helical edge states of a quantum spin Hall insulator is experimentally characterized by a weakly temperature-dependent mean free path of a few microns and by reproducible conductance oscillations, challenging ... -
Intrinsic magnetization of antiferromagnetic textures
(Journal article, 2016)Antiferromagnets (AFMs) exhibit intrinsic magnetization when the order parameter spatially varies. This intrinsic spin is present even at equilibrium and can be interpreted as a twisting of the homogeneous AFM into a state ... -
Photoemission spectroscopies and their application in solid state and material physics
(Doctoral thesis at NTNU;2016:97, Doctoral thesis, 2016)Understanding the electronic properties of solid state systems is of fundamental importance to all matter. In particular, understanding and tailoring the properties of bound electrons in materials is an indispensable step ... -
The effects and behaviour of Li and Cu alloying agents in lean Al-Mg-Si alloys
(Journal article, 2016)We show how replacing a fraction of Mg with Li in a lean Al-Mg-Si alloy gives comparable strength and enhanced temperature stability. Replacing solute with smaller amounts of Cu and Li also improves thermal stability and ... -
Competitive ligand exchange of crosslinking ions for ionotropic hydrogel formation.
(Journal article; Peer reviewed, 2016)Currently there are limitations to gelation strategies to form ionically crosslinked hydrogels, derived in particular from a lack of control over the release kinetics of crosslinking ions, which severely restrict applications. ...
