Characterization of anisotropy in articular cartilage samples using magnetic resonance imaging (MRI) and multiphoton microscopy (MPM)
(Master thesis, 2016)Articular cartilage is a thin flexible tissue found at the ends of the bones in a joint that provides a lubricated surface for articulation and distribute loads with low friction. However, due to degenerative diseases, ... -
Surface Acoustic Wave Acoustophoresis for Microfluidic Based Micron and Submicron Particle Separation
(Master thesis, 2016)Microvesicles secreted from our cells referred to as exosomes contain vital information on our health status and are believed to revolutionize early diagnosis. Therefore, separation of such particles is a growing field ... -
Zigzag-Shaped Superlattices on the Basis of Graphene Nanoribbons: Structure and Electronic Properties
(Journal article; Peer reviewed, 2016)The paper focuses on superlattices consisting of two coplanar fragments of one-layer graphene nanoribbons that have different width and are connected at an angle. Classification of such superlattices was carried out; their ... -
Density Functional Theory Studies of Precipitate Interfaces in Aluminium Alloys, with Focus on Theta'-Al2Cu
(Master thesis, 2016)The atomic structure of bulk crystal of aluminium and the precipitate phase $\theta^\prime$ connected to age-hardening of Al-Cu alloys have been studied using Density Functional Theory (DFT). The lattice constant of ... -
Nanoscale Structure and Spectroscopic Probing of Aβ1-40 Fibril Bundle Formation
(Peer reviewed; Journal article, 2016)Amyloid plaques composed of fibrillar Amyloid-β (Aβ) are hallmarks of Alzheimer's disease. However, Aβ fibrils are morphologically heterogeneous. Conformation sensitive luminescent conjugated oligothiophenes (LCOs) are ... -
Compositional and structural properties of pulsed laser-deposited ZnS:Cr films
(Journal article; Peer reviewed, 2016)We present the properties of Cr-doped zinc sulfide (ZnS:Cr) films deposited on Si(100) by pulsed laser deposition. The films are studied for solar cell applications, and to obtain a high absorption, a high Cr content ... -
Transformation of brushite to hydroxyapatite and effects of alginate additives
(Journal article; Peer reviewed, 2016)Phase transformations are important processes during mineral formation in both in vivo and in vitro model systems and macromolecules are influential in regulating the mineralization processes. Calcium phosphate mineralized ... -
Estimation of Design Snow Loads on Offshore Structures in the Barents Sea
(Master thesis, 2016)Snow accumulating on offshore structures can reduce freeboard and stability, block equipment and valves, and reduce operability of the platform or ship. It is thus important to evaluate snow conditions before starting long ... -
Methodology for optimal energy system design of Zero Energy Buildings using mixed-integer linear programming
(Journal article, 2016)According to EU’s Energy Performance of Buildings Directive (EPBD), all new buildings shall be nearly Zero Energy Buildings (ZEB) from 2018/2020. How the ZEB requirement is defined has large implications for the choice of ... -
The reality of Casimir friction
(Journal article; Peer reviewed, 2016)For more than 35 years theorists have studied quantum or Casimir friction, which occurs when two smooth bodies move transversely to each other, experiencing a frictional dissipative force due to quantum electromagnetic ... -
Refinement of the ζ-factor Method for Quantitative Energy-Dispersive X-ray Spectroscopy in Scanning Transmission Electron Microscopy
(Master thesis, 2016)The ζ-factor method for quantitative energy-dispersive X-ray spectroscopy (EDS) has been implemented using the open source Python-based HyperSpy library. The ζ-factors for Ga, As, Al, C and Sb have been determined ... -
Manipulating Spins in Antiferromagnets with External Forces
(Doctoral thesis at NTNU;2016:114, Doctoral thesis, 2016)This thesis presents five papers on theoretical spintronics. Four of the papers describe antiferromagnets and the interactions between the magnetic order parameter and external forces induced by charge currents, spin ... -
