Direct Determination of Chitosan–Mucin Interactions Using a Single-Molecule Strategy: Comparison to Alginate–Mucin Interactions
(Journal article; Peer reviewed, 2015)Aqueous chitosan possesses attractive interaction capacities with various molecular groups that can be involved in hydrogen bonds and electrostatic and hydrophobic interactions. In the present paper, we report on the direct ... -
Intercalation and Retention of Carbon Dioxide in a Smectite Clay promoted by Interlayer Cations
(Journal article; Peer reviewed, 2015)A good material for CO2 capture should possess some specific properties: (i) a large effective surface area with good adsorption capacity, (ii) selectivity for CO2, (iii) regeneration capacity with minimum energy input, ... -
Characterisation of quasi-stationary planetary waves in the Northern MLT during summer
(Journal article; Peer reviewed, 2015)Observations of planetary wave (PW) activity in the northern hemisphere, polar summer mesosphere and lower thermosphere (MLT) are presented. Meteor winds from a northern hemisphere chain of SuperDARN radars have been used ... -
Evidence of chromium-cobalt binary cluster formation by pulsed laser evaporation
(Journal article, 2015)We report on the use of time of flight mass spectrometry to investigate the cluster spectrum resulting from Nd-YAG ablation of a Co-Cr target. Cr+ clusters dominated the spectrum, with Co+ clusters as the second most intense ... -
Parallel integration of aligned carbon strings in polymer composite: Dielectrophoretic preparation, finite element simulation, and electrical characterization
(Journal article; Peer reviewed, 2015)We report on dielectrophoretic alignment of carbon black particles into radially arranged string-like assemblies in oligourethane mixtures followed by photopolymerization. Using finite element modelling and optical microscopy ... -
Investigating the Local Load Sharing Fibre Bundle Model in Higher Dimensions
(Master thesis, 2015)We introduce a generalization of the history-independent local load sharing fibre bundle model that is valid in arbitrarily high dimensions, and study this model numerically in one to five dimensions. Simulations show ... -
Tunable high aspect ratio polymer nanostructures for cell interfaces
(Journal article; Peer reviewed, 2015)Nanoscale topographies and chemical patterns can be used as synthetic cell interfaces with a range of applications including study and control of cellular processes. Herein, we describe the fabrication of high aspect ratio ... -
Doped ZnS Thin Films for Intermediate Band Solar Cells - Deposition and Characterization
(Master thesis, 2015)Intermediate band solar cells (IBSCs) has the potential of increasing the efficiency and reducing the cost of commercial solar cells. The realization of such cells relies on the development of intermediate band (IB) ... -
Terahertz Time-Domain Spectroscopy of Thin Material Samples
(Master thesis, 2015)This thesis describes the techniques used in terahertz time-domain spectroscopy to determine the optical properties of layers that are thin compared to the length of the terahertz pulse. An iterative procedure is used to ... -
Intermediate Band Solar Cells: Simulations and Quantum Dot Studies
(Doctoral thesis at NTNU;2015:85, Doctoral thesis, 2015)Silicon solar cell technology is now a mature technology and competitive with other energy technologies in many energy markets worldwide. However, to have major contribution to the electricity generation higher energy ... -
Investigation of Raman scattering phenomena in the development of mid-IR ultra-short laser pulses
(Master thesis, 2015)In this thesis both a raman spectrometer and a dispersion measurement setup for fibers was designed, built and automatized. Furthermore several nonlinear phenomena were researched and with two different approaches simulated. ... -
Osteogenic differentiation of human mesenchymal stem cells in mineralized alginate matrices
(Journal article; Peer reviewed, 2015)Mineralized biomaterials are promising for use in bone tissue engineering. Culturing osteogenic cells in such materials will potentially generate biological bone grafts that may even further augment bone healing. Here, ... -
Analysis of the ZnO/Cu2O Thin Film Heterojunction for Intermediate Band Solar Cell Applications
(Master thesis, 2015)In an attempt to increase the maximum theoretical efficiency of solar cells, one proposed device is called intermediate band solar cells (IBSC). The candidate material system chosen for this study is nitrogen doped cuprous ... -
Spin- and Charge-Supercurrent and Density of States in Diffusive Spin-Active Josephson Junctions
(Master thesis, 2015)In this thesis we investigate theoretically the properties of spin-active Josephson junctions, using a normal metal as the weak link. The system is examined both analytically in the weak proximity effect regime and numerically ... -
