Dislocation dynamics study of precipitate hardening in Al-Mg-Si alloys with input from experimental characterization
(Journal article; Peer reviewed, 2017)Partial aging of AA6060 aluminum alloys is known to result in a microstructure characterized by needle-shaped Si/Mg-rich precipitates. These precipitates belong to the non-equilibrium β″ phase and are coherent with the ... -
Disorder-induced non-linear growth of fingers in immiscible two-phase flow in porous media
(Journal article; Peer reviewed, 2024)Immiscible two-phase flow in porous media produces different types of patterns depending on the capillary number Ca and viscosity ratio M. At high Ca, viscous instability of the fluid–fluid interface occurs when the displaced ... -
Dispersion hardening during annealing at low Temperatures in four 3xxx Al-Mn-Fe-Si Alloys
(Master thesis, 2012)3xxx aluminiumslegeringer har Mangan som hovedlegeringselement, og får sin styrke fra plastisk bearbeidelse. 3xxx legeringer har tidligere blitt ansett for å oppnå neglisjerbare endringer i hardhet og styrke som følge av ... -
Dispersion Measurement of Infrared Specialty Fibers
(Chapter, 2012)We demonstrate broadband (>250nm) dispersion measurements and theoretical calculations in a set of short-length specialty fibers in the 2.16-2.41µm wavelength range for femtosecond mid-IR applications using an ultrabroadband ... -
Dispersion of polarization coupling, localized and collective plasmon modes in a metallic photonic crystal mapped by Mueller Matrix Ellipsometry
(Journal article; Peer reviewed, 2015)We report a spectroscopic Mueller matrix experimental study of a plasmonic photonic crystal consisting of gold hemispheroidal particles (lateral radius 54 nm, height 25 nm) arranged on a square lattice (lattice constant ... -
Dispersion of resonant modes in patch antenna lattices
(Journal article; Peer reviewed, 2022)Spectroscopic polar angle resolved Mueller matrix ellipsometry at multiple azimuthal incidences, together with a full-field model, reveal new details in the interplay between localized gap surface plasmon resonances and ... -
Dispersionsrelasjonen til magnoner i ultratynne Co filmer grodd på Ir(111)
(Master thesis, 2019)I denne masteroppgaven har de magnetiske egenskapene til en 1.6 ML Co film, grodd på et Ir(111) substrat, blitt undersøkt ved hjelp av spin-polarisert elektron energitap spektroskopi (SPEELS). To magnon-eksitasjonstopper ... -
Dissipative quantum phase transitions and high-temperature superconductors
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:229, Doctoral thesis, 2012)This thesis presents seven research papers on topics in condensed-matter theory. Five of the papers report on Monte Carlo studies of quantum phase transitions in various (d+1)-dimensional statistical mechanics models ... -
Dissolution of copper mineral phases in biological fluids and the controlled release of copper ions from mineralized alginate hydrogels
(Journal article; Peer reviewed, 2015)Here we investigate the dissolution behaviour of copper minerals contained within biocompatible alginate hydrogels. Copper has a number of biological effects and has most recently been evaluated as an alternative to expensive ... -

DNA aptamer functionalized hydrogels for interferometric fiber-optic based continuous monitoring of potassium ions
(Peer reviewed; Journal article, 2021)In the present paper, we describe a potassium sensor based on DNA-aptamer functionalized hydrogel, that is capable of continuous label-free potassium ion (K+) monitoring with potential for in situ application. A hydrogel ... -
DNA compaction induced by a cationic polymer or surfactant impact gene expression and DNA degradation
(Journal article; Peer reviewed, 2014)There is an increasing interest in achieving gene regulation in biotechnological and biomedical applications by using synthetic DNA-binding agents. Most studies have so far focused on synthetic sequence-specific DNA-binding ... -
DNA Condensation by Peptide-Conjugated PAMAM Dendrimers. Influence of Peptide Charge
(Peer reviewed; Journal article, 2023)Nucleic acid delivery to cells is an important therapeutic strategy that requires the transport of nucleic acids to intracellular compartments and their protection from enzymatic degradation. This can be achieved through ... -
Does the Boson Peak Exist in 2D Materials?
