Plasmonics for Light Trapping in Thin Silicon Solar Cells
(Master thesis, 2011)The cost of the wafer represents a significant share of the cost of a solar module. One way to reduce it is to reduce the wafer thickness. However, this leads to increases in the transmission of the sunlight through the ... -

Polarimetry using classical polarizing components and nanostructured beam splitting surfaces
(Master thesis, 2018)Two methods for generation and analysis of the polarization state of light are studied in this thesis. The first method is based on a traditional bulk design consisting of two active components and 3 passive components in ... -
Polarization beam-splitting metasurfaces analyzed using the finite-difference time-domain software EMTL
(Master thesis, 2018)Using the FDTD solver EMTL, as well as a new way of thinking about metasurfaces, the primary innovation of this thesis was to take two individual birefringent patterns and interleave them in a checkered pattern. This ... -
Polyelectrolyte complexes and multilayers assembled from biopolymers : electrostatically driven formation of mesoscale structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:127, Doctoral thesis, 2004)Oppositely charged polyelectrolytes interact spontaneously upon mixing. This interaction can be exploited to form polyelectrolyte complexes and polyelectrolyte multilayers. In the latter case the interaction takes place ... -
Polyethylene glycol (PEG) as a broad applicability marker for LC–MS/MS-based biodistribution analysis of nanomedicines
(Journal article; Peer reviewed, 2024)Polyethylene glycol (PEG) conjugation (PEGylation) is a well-established strategy to improve the pharmacokinetic and biocompatibility properties of a wide variety of nanomedicines and therapeutic peptides and proteins. ... -
Polymer sequencing by molecular machines: a framework for predicting the resolving power of a sliding contact force spectroscopy sequencing method
(Journal article, 2017)We evaluate an AFM-based single molecule force spectroscopy method for mapping sequences in otherwise difficult to sequence heteropolymers, including glycosylated proteins and glycans. The sliding contact force spectroscopy ... -
Polymeric nanoparticles for intraperitoneal cancer treatment: Development and characterisation of a novel drug delivery platform
(Doctoral theses at NTNU;2023:97, Doctoral thesis, 2023)The emerging field of nanomedicine allows development of drug delivery systems that improve the efficiency and bioavailability of therapeutics. Poly(alkyl cyanoacrylate) (PACA) nanoparticles have been widely studied as ... -

Porous Coatings Containing Copper and Phosphorus Obtained by Plasma Electrolytic Oxidation of Titanium
(Journal article; Peer reviewed, 2020)To fabricate porous copper coatings on titanium, we used the process of plasma electrolyticoxidation (PEO) with voltage control. For all experiments, the three-phase step-up transformer withsix-diode Graetz bridge was used. ... -
Positive Partial Transpose States in Multipartite Quantum Systems
(Master thesis, 2012)In this master thesis I study the extremal positive partial transpose (PPT) states of the three qubit $(2times2times2)$ system using numerical methods. Using two algorithms which locate PPT states of a specified rank and ... -
Possible odd-frequency Amperean magnon-mediated superconductivity in topological insulator–ferromagnetic insulator bilayer
