Production and Application of Micronsized Polysaccharide Particles - Studying Perturbation of a Model Mucus Barrier with Total Internal Reflection Fluorescence (TIRF) Microscopy and Atomic Force Microscopy (AFM) Indentation
(Master thesis, 2011)The overall aim of this project was to produce homogeneously sized polysaccharide microparticles and apply these and similar sized particles as probes for investigation of mucin layers as a model for a biological barrier. ... -
Kven vart fysikkstudenten?: Ei undersøking av avgangsstudentar sine interesser, inspirasjonskjelder og framtidsplanar.
(Master thesis, 2011)I denne oppgåva har eg studert avgansstudentar i fysikk sitt syn på studietida og framtida. Forskingsspørsmåla fokuserer på kva læringsaktivitetar studentane har likt, kva som har motivert dei gjennom studietida og kva ... -
Nonlinear Laser-induced Deformations and Forces at Liquid-Liquid Interfaces near the critical Point.
(Master thesis, 2011)The theory of laser-induced liquid-liquid interface deformation has been presented and used to derive a differential equation describing the shape of the deformation. The differential equation has been investigated and ... -
Complex Networks: Development of a three particle reaction-diffusion model on a complex network.
(Master thesis, 2011)This master thesis couples endemic modeling of diseases with complex networks and diffusion. Previous established models are visited and results for these are reproduced. The goal of this thesis was to expand upon these ... -
Characterization of ZnS:Cr films for Intermediate Band Solar Cells
(Master thesis, 2011)In this thesis samples of ZnS:Cr thin films have been made through physicalvapor deposition (PVD) with resistive heating and characterized by severalmethods. The thin films are of various thicknesses and contain ... -
Josephson effect in S/F/S junctions: Spin bandwidth asymmetry versus Stoner exchange
(Journal article; Peer reviewed, 2011)We analyze the dc Josephson effect in a ballistic superconductor/ferromagnet/superconductor junction by means of the Bogoliubov–de Gennes equations in the quasiclassical Andreev approximation. We consider the possibility ... -
Maximum Entropy and Maximum Entropy Production in Macroecology
(Master thesis, 2011)The Maximum Entropy Theory of Ecology (METE), developed by John Harte, presents an entirely new method of making inferences in ecology. The method is based on the established mathematical procedure of Maximum Information ... -
Real-time Study of the Formation of GaSb Nanopillars by Spectroscopic Mueller Matrix Ellipsometry
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:208, Doctoral thesis, 2011)The formation of GaSb nanopillars have been studied in real-time by spectroscopic Mueller matrix ellipsometry. Low energy ion sputtering of GaSb leads to the formation of densely packed nanopillars on the surface. A graded ... -
Aura MLS observations of the westward-propagating s=1, 16-day planetary wave in the stratosphere, mesosphere and lower thermosphere
(Journal article; Peer reviewed, 2011)The Microwave Limb Sounder (MLS) on the Aura satellite has been used to measure temperatures in the stratosphere, mesosphere and lower thermosphere. The data used here are from August 2004 to December 2010 and latitudes ... -
Winds and tides in the mid-latitude southern hemisphere upper mesosphere recorded with the Falkland Islands SuperDARN radar
(Journal article; Peer reviewed, 2011)Meteor wind data from the first year of operation of the Falkland Islands SuperDARN radar (52 S, 59 W) are used to characterize the atmospheric tides and background winds in the upper mesosphere above the South Atlantic. ... -
A Study of Cultured Cells on a Nanowire-based Reverse Transfection Device
(Master thesis, 2011)This work builds on previous research at NTNU into the use of vertically aligned copper oxide nanowire arrays as a versatile system to deliver biomolecules into cultured adherent mammalian cells. The background for the ... -
Case study of a mesospheric wall event over Ferraz station, Antarctica (62 degrees S)
(Journal article; Peer reviewed, 2011)On 16–17 July 2007 during an observational campaign at Comandante Ferraz Antarctic Station (62° S, 58° W), a mesospheric wall was observed with an airglow all-sky imager. The wave appeared like an extensive dark region in ... -
Diffuse Small Angle X-Ray Scattering From Thin Film Structures In the Distorted Wave Born Approximation
(Master thesis, 2011)The differential scattering cross section for diffuse scattering of X-rays from thinfilm structures is discussed within the framework of the distorted wave Born ap-proximation (DWBA). In contrast to the standard Born ... -
Ferromagnetic Resonance of LSMO Thin Film
(Master thesis, 2011)The magnetic properties of a 15uc thick LSMO thin film on SrTiO3 (STO) substrate atT=150K was investigated using the technique of ferromagnetic resonance (FMR). The FMRmeasurement of the 15uc thick LSMO thin film at a ... -
Density Functional Theory Investigations of Surface Structure and Reactivity
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:93, Doctoral thesis, 2011)The Cr2O3(0001) surface is assumed to terminate by chromium atoms, chromyl groups, and oxygen atoms. This essentially models the industrial surface when subjected to different oxygen chemical potentials. The issue of high ... -
Controllable spin-transfer torque on an antiferromagnet in a dual spin-valve
(Journal article; Peer reviewed, 2011)We consider current-induced spin-transfer torque on an antiferromagnet (AFM) in a dual spin-valve setup. It is demonstrated that a net magnetization may be induced in the AFM by partially or completely aligning the sublattice ... -
Human Exposure Assessment of Engineered Inorganic Nanoparticles in Food
(Master thesis, 2011)An increasingly important part of food technology is nanotechnology. Inorganic nanoparticles are added directly or indirectly to food in order to create new tastes, appetizing looks or to preserve it longer. Exposure to ... -
