The Influence of the Energy Degrader Material for a Therapeutical Proton Beam
(Master thesis, 2015)In cyclotron based proton therapy an energy degrader is needed to modulate the proton beam energy. The proton beam energy decides the range of the particles and thereby where the dose is imparted. The influence of the ... -
Developing Methods and Tools for Three-Dimensional Computational Reconstructions in X-ray and Visible Light Microscopy
(Master thesis, 2015)In this thesis possibilities for further developments in microscopy have been explored. This was done through two sub-projects: The first project was on small-angle X-ray (SAXS) tomography, and the second revolved around ... -
Properties of transition metal doped cadmium sulfide hexamers and dodecamers
(Journal article; Peer reviewed, 2015)The electronic and geometrical properties of endohedrally and substitutionally doped Cd6S6 and Cd12S12 clusters were analyzed by means of Density Functional Theory. The results are compared to those of ZnS clusters of the ... -
Nucleation and Growth of Brushite in the Presence of Alginate
(Journal article, 2015)Biomineral formation in vivo is a complex process regulated by functional molecules. Highlighting the mechanisms underlying biomineralization is necessary for a better understanding of in vivo processes and for enhanced ... -
Silicon microwires as solar cells
(Doctoral thesis at NTNU;2015:235, Doctoral thesis, 2015)In this work it has been shown that microwire radial junction solar cells can be realized from silicon core glass fibers made via the molten core fiber drawing method starting with low quality silicon. Through a ... -
Electromagnetic Principles for In Situ Ice Thickness Determination - Field Experiments and Development of New Methods for Interpretation
(Master thesis, 2015)During the spring of 2014 fieldwork in three different locations on Svalbard was conducted in order to investigate the application of electromagnetic methods on sea ice and ice ridges. Two validation grids, one transect ... -
Self-Assembly of Magnetic Nanoparticles into Superstructures for Magnonics
(Master thesis, 2015)Magnonics is a young and evolving field with the potential to replace conventional electronics. This field relies on the use of spin waves, or magnons, rather than electrons as the information carrier in logic devices, ... -
Biophysical Studies of Light Sensitive Chromophores in Rat Glioma and Chinese Hamster Ovary Cancer Cells
(Master thesis, 2015)The aim of this study was to investigate the biophysical properties of four light sensitive chromophores as a fluorescence dye for bioimaging applications, or photosensitizer in photodynamic therapy (PDT). Characterization ... -
Critical temperature and tunneling spectroscopy of superconductor-ferromagnet hybrids with intrinsic Rashba-Dresselhaus spin-orbit coupling
(Journal article, 2015)We investigate theoretically how the proximity effect in superconductor/ferromagnet hybrid structures with intrinsic spin-orbit coupling manifests in two measurable quantities, namely the density of states and critical ... -
Kombinert summativ og formativ vurdering i matematikk
(Peer reviewed; Journal article, 2015)Artikkelen framlegger resultater fra et undervisningsopplegg i matematikk for 1. års ingeniørstudenter ved HiST høsten 2013, hvor korte, digitale flervalgstester inngikk som en del av den summative vurderingen i matematikkfaget. ... -
Micro- and nanostructured devices for cell studies
(Doctoral thesis at NTNU;2015:240, Doctoral thesis, 2015)Cell culture is a fundamental and valuable tool for modern biomedical research. The purpose of this work has been to expand the possibilities and methods of cell culture through engineering of the cell culture substrate. ... -
Svak Verdi - Et studie i egenskaper ved, og observasjoner av, svake verdier
(Master thesis, 2015)Prosessen for måling av svak verdi er blitt gjennomgått, debatten rundt betydningen av den svake verdien og dens rolle i forklaringen av kjente paradokser har blitt belyst. Det har blitt gjennomgått en modell for, og et ... -

Giant triplet proximity effect in π-biased Josephson junctions with spin-orbit coupling
(Journal article, 2015)In diffusive Josephson junctions the phase difference φ between the superconductors strongly influences the spectroscopic features of the layer separating them. The observation of a uniform minigap and its phase modulation ... -
Intrinsic paramagnetic meissner effect due to s-wave odd-frequency superconductivity
(Journal article; Peer reviewed, 2015)Since its discovery in 1911, superconductivity has remained one of the most intriguing phase transitions in the field of condensed-matter physics. Superconductivity, which occurs in certain materials cooled below a critical ... -
Protein Binding and Crowding Effects on DNA Condensation
(Master thesis, 2015)The main goal of this work is to map how bacterial nucleoid associated proteins (NAPs) condense DNA in tandem with a crowded environment, since this may provide useful information for research where DNA compaction and ... -
Effekter av manglende Lorentz-invarians på Nambu-Goldstone bosoner
(Master thesis, 2015)I denne avhandlingen diskuterer vi symmetrier av feltteorier både med og uten Lorentz-invarians. Vi konstruerer en feltteori fri for interaksjoner som er invariant under den Euklidske gruppen E(2), har tilhørende Euler-Lagrange ... -
Targeting kinetics of RGD-conjugated nanoemulsions
