Cellular Interaction with Polymeric Nanoparticles: The Effect of PEGylation and Monomer Composition
(Master thesis, 2013)It is of importance to understand which nanoparticle properties that govern the interactions between particles and cells, in order to develop a nanocarrier with the desired functionality. In this thesis, nanoparticles made ... -
Mechanisms for delivery of hydrophobic drugs from polymeric nanoparticles to cancer cells
(Master thesis, 2013)Encapsulation of drugs in nanoparticles could facilitate the accumulation of drugs in the tumor leading to less side effects and improved efficacy of the drug compared to conventional non-specific treatment interventions. ... -
3W Raman Soliton Tunable between 2-2.2 µm in Tm-Doped Fiber MOPA
(Chapter, 2013)The simple and compact Tm-doped fiber MOPA generates tunable between 2-2.2 µm Raman solitons with average power up to 3W. Pulses as short as 130 fs and energy up to 38 nJ were demonstrated. -
Loss Measurements in Silicon Core Optical Waveguides
(Master thesis, 2013)Silicon core fibers have, because of their non-linear optical properties and transmission in the IR, recently been the focus of several different research groups. At NTNU, a new method for production of silicon fibers has ... -
Electrohydrodynamic Structuring of Colloidal Particles on Leaky Dielectric Drops
(Master thesis, 2013)This Master's thesis shows experimentally how colloidal particles in leakydielectric liquid drops are actively structured by applying a DC electric eld.Colloidal particles in small droplets with a diameter of 100 m show ... -
Entropy in Dynamical Networks
(Master thesis, 2013)This thesis presents a new type of dynamical entropy, defined by the movement of particles beetween the nodes in a network. The entropy is intended to have similar properties as the well-known thermodynamic entropy. ... -
Quantum Transport in Hybrid Structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:231, Doctoral thesis, 2013)This thesis presents the findings of four research papers on two topics in condensed-matter physics. Namely: i) The interplay between superconductivity and magnetism in Josephson junctions, and ii) current-driven domain ... -
Comparison of Dose Distributions resulting from IMRT and VMAT, and Assessment of MLC Leaf Positioning Errors
(Master thesis, 2013)Intensity-modulated radiotherapy (IMRT) is a radiation technique used in the treatment of head-and-neck cancer patients. IMRT results in a dose distribution which conforms to the tumor volume(s), and therefore sparing ... -
Kerr-lens mode-locked Cr:ZnS laser
(Journal article; Peer reviewed, 2013)We report the soft-aperture Kerr-lens mode-locked Cr:ZnS laser, generating 550 mW of 69 fs nearly transform-limited pulses at 2.39 μm wavelength. The pulse energy reached 3.8 nJ at 145 MHz repetition rate, limited by the ... -
Delivery of Encapsulated Drugs to Cancer Cells and Tissue: The Impact of Ultrasound
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:57, Doctoral thesis, 2013)Encapsulated drugs have improved tumor to normal tissue uptake compared to free drugs, however, the concentration of drugs at the tumor site is still low and heterogeneous due to the tumor microenvironment which serves as ... -
Optical properties of biaxial nanopatterned gold plasmonic nanowired grid polarizer
(Journal article; Peer reviewed, 2013)Gold nanoparticles deposited on self-organized nano-ripple quartz substrates have been studied by spectroscopic Mueller matrix ellipsometry. The surface was found to have biaxial anisotropic optical properties. For electric ... -
Spectral correlation analysis of Amyloid beta plaque inhomogeneity from double staining experiments
(Journal article; Peer reviewed, 2013)A spectral correlation algorithm for the analysis of hyperspectral fluorescence images is proposed by Ellingsen et al. [J. Biomed. Opt. 18, 020501 (2013)]. Here, it is applied to the analysis of double-stained Aβ amyloid ... -
Statistics of Electric Power Blackouts: Data Analysis and Data Modeling
(Master thesis, 2013)We tried to see the scaled window variance and rescaled window variance statistics of the North American, Norwegian and Ethiopian blackouts. Beside we also see the square lattice modelling of blackout distribution. The ... -
Validation of middle-atmospheric campaign-based water vapour measured by the ground-based microwave radiometer MIAWARA-C
(Journal article; Peer reviewed, 2013)Abstract. Middle atmospheric water vapour can be used as a tracer for dynamical processes. It is mainly measured by satellite instruments and ground-based microwave radiometers. Ground-based instruments capable of measuring ... -
Pressure Fluctuations in Steady State Two-Phase Flow in Porous Media
(Master thesis, 2013)Several aspects of two-phase flow in porous are examined numerically.The burst size distributions in both the invasion phase and steady stateare computed; above a threshold, the steady state distribution is found tobe ... -
High resolution characterization of responsive hydrogels for biomedical application
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:72, Doctoral thesis, 2013)Hydrogels are 3D polymer network that, differing from conventional solids, can eliminate or absorb water and as a consequence undergo changes in volume, mechanical properties. Various properties of the hydrogels can be ... -
