Nonlinear optical microscopy and Raman spectroscopy analysis of Osteoarthritis
(Doctoral thesis at NTNU;2015:113, Doctoral thesis, 2015)Can Osteoarthritis be diagnosed at an early stage? Osteoarthritis (OA) is a highly prevalent, disabling, complex joint disorder, and a leading cause of individual and socioeconomic burden. The tissue that contributes ... -
Modeling surface nanobubbles in water electrolysis
(Master thesis, 2015)In this project a steady state approach is used to study the stability of surface nanobubbles in water electrolysis. A two dimensional domain is considered, where an electrode of length 100 nm is partly covered by a bubble. ... -
Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery
(Journal article, 2015)Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology ... -
Dispersion of polarization coupling, localized and collective plasmon modes in a metallic photonic crystal mapped by Mueller Matrix Ellipsometry
(Journal article; Peer reviewed, 2015)We report a spectroscopic Mueller matrix experimental study of a plasmonic photonic crystal consisting of gold hemispheroidal particles (lateral radius 54 nm, height 25 nm) arranged on a square lattice (lattice constant ... -
Spin supercurrent and phase-tunable triplet Cooper pairs via magnetic insulators
(Journal article, 2015)We demonstrate theoretically that a dissipationless spin current can flow a long distance through a diffusive normal metal by using superconductors interfaced with magnetic insulators. The magnitude of this spin supercurrent ... -
Density of States and Critical Temperature in Superconductor/Ferromagnet Structures with Spin-Orbit Coupling
(Master thesis, 2015)We present both an analytical discussion of the weak proximity regime, and a full numerical investigation of the strong proximity regime. The results show that the spin-orbit coupling leaves a clear trace in the density ... -
TEM of Chromium doped Zinc Sulfide Thin Films for Solar Cell Applications.
(Master thesis, 2015)To Cr dopede ZnS tynnfilmer grodd ved forskjellig temperatur har blitt undersøkt med transmisjons elektronmikroskopi. Krystallstrukturen til filmene ble undersøkt med høyoppløsningsbilder og diffraksjonsmønstre. Begge ... -
High Temperature Decomposition of Methane on Quartz Pellets
(Master thesis, 2015)This work has shown that pure methane, when exposed to quartz at a temperatures of 900°C and 1000°C, cracks and deposits carbon at a near constant rate. The deposition rates for the individual temperature levels were shown ... -
Topology of Fracture Networks
(Doctoral thesis at NTNU;2015:200, Doctoral thesis, 2015)This thesis is submitted as partial fulfilment of the requirements for the degree of philosophiae doctor. Methods from network science are applied to investigate the topology of fracture networks. The main focus is on ... -
Mechanical and Acoustic Characterization of Perfluorocarbon Microbubbles Containing Nanoparticles
(Master thesis, 2015)In order to optimize the production and behaviour of ultrasound contrast agents it is necessary to map their characteristics. The aim of this master's thesis is to investigate different batches of perfluoropropane microbubbles ... -
The Distribution of Spatial Phases of Grid Cells
(Master thesis, 2015)Grid cells, found in the medial entorhinal cortex of mammalian brains, are among the most significant discoveries from the research into the brain's system for spatial navigation during the last decades. A lot of work has ... -
Structural investigation of epitaxial LaFeO3 thin films on (111) oriented SrTiO3 by transmission electron microscopy
(Journal article; Peer reviewed, 2015)We report on structural domains in LaFeO3 epitaxial thin films on (111) oriented SrTiO3 observed by transmission electron microscopy using low magnification dark field imaging and high resolution transmission electron ... -
Active matter - Collective Motion due to Quincke Rotation
(Master thesis, 2015)his thesis investigates Quincke induced collective motion. It is mostly a qualitative study, but it attempts to connect Quincke induced collective motion to the field of active matter as a whole. The thesis has two objectives. ... -
A study of eddy current field interactions in ferromagnetic / normal metal thin film structures and its impact on ferromagnetic resonance
(Master thesis, 2015)This study investigates the eddy current field interaction in ferromagnetic (FM) / normal-metal (NM) thin film structures and its impact on ferromagnetic resonance (FMR). Eddy currents correspond to circulating currents ... -
Ultrasound in Imaging and Delivery of Nanomedicine in Cancer Tissue
(Doctoral thesis at NTNU;2015:27, Doctoral thesis, 2015)Nanotechnology in therapy of solid tumors is a strategy where the cytotoxic drugs are encapsulated into nano-sized particles. It is expected that therapy using nanomedicine will result in both increased specificity of the ... -
Observations of planetary waves in the mesosphere-lower thermosphere during stratospheric warming events
(Journal article; Peer reviewed, 2015-05-04)This study investigates the effect of stratospheric sudden warmings (SSWs) on planetary wave (PW) activity in the mesosphere–lower thermosphere (MLT). PW activity near 95 km is derived from meteor wind data using a chain ... -
Topological impact of constrained fracture growth
(Journal article; Peer reviewed, 2015-09-08)The topology of two discrete fracture network models is compared to investigate the impact of constrained fracture growth. In the Poissonian discrete fracture network model the fractures are assigned length, position and ... -
Network topology of the desert rose
(Journal article; Peer reviewed, 2015-09-08)Desert roses are gypsum crystals that consist of intersecting disks. We determine their geometrical structure using computer assisted tomography. By mapping the geometrical structure onto a graph, the topology of the desert ... -
