Bulk fabrication and properties of solar grade silicon microwires
(Journal article; Peer reviewed, 2014)We demonstrate a substrate-free novel route for fabrication of solar grade silicon microwires for photovoltaic applications. The microwires are fabricated from low purity starting material via a bulk molten-core fibre ... -
Bulk substitution of F-terminations from Ti3C2Tx MXene by cation pillaring and gas hydrolysation
(Journal article, 2023)Applications of 2D MXenes are limited by the difficulty of controlling bulk termination groups after the initial HF etching step without forming surface oxides. Here, we report on gas hydrolysation using a continuous flow ... -
Burst Distribution by Asymptotic Expansion in the Equal Load Sharing Fiber Bundle Model
(Journal article; Peer reviewed, 2019)We derive an asymptotic series expansion for the burst size distribution in the equal load sharing fiber bundle model, a predominant model for breakdown in disordered media. Earlier calculations give expressions with correct ... -
Burst Dynamics, Upscaling and Dissipation of Slow Drainage in Porous Media
(Peer reviewed; Journal article, 2021)We present a theoretical and experimental investigation of drainage in porous media. The study is limited to stabilized fluid fronts at moderate injection rates, but it takes into account capillary, viscous, and gravitational ... -

Cabazitaxel-loaded Poly(2-ethylbutyl cyanoacrylate) nanoparticles improve treatment efficacy in a patient derived breast cancer xenograft
(Journal article; Peer reviewed, 2018)The effect of poly(2-ethyl-butyl cyanoacrylate) nanoparticles containing the cytotoxic drug cabazitaxel was studied in three breast cancer cell lines and one basal-like patient-derived xenograft model grown in the mammary ... -
Calcite seed-assisted microbial induced carbonate precipitation (MICP)
(Peer reviewed; Journal article, 2021)Microbial-induced calcium carbonate precipitation (MICP) is a biological process inducing biomineralization of CaCO3. This can be used to form a solid, concrete-like material. To be able to use MICP successfully to produce ... -
Calculation of Terminal Currents in Single Photon Excited Avalanche Photodiodes.
(Master thesis, 2012)We use the Shockley-Ramo (SR) theorem to calculate terminal currents in single photon excited APDs. A unified notation for the SR theorem is introduced, and we derive the theorem in those particular ways found useful for ... -
Calculation of the Breit-Rosenthal Effect in Pb I
(Master thesis, 2023)\chapter{Sammendrag på Norsk}\label{Norsk} Atomer er grunnleggende byggeklosser for materie, bestående av en atomkjerne med protoner og nøytroner, og en sky av elektroner som omslutter den. Studie av atomers egenskaper ... -
Calculation of the Differential Breit–Rosenthal Effect in the 6s6p ^3p_1,2 States of Hg
(Peer reviewed; Journal article, 2020)Studies of the hyperfine anomaly has found a renewed interest with the recent development of techniques to study the properties of long chains of unstable nuclei. By using the hyperfine structure for determining the nuclear ... -
Calculation of Wavefunction Overlaps in First Principles Electronic Structure Codes
(Master thesis, 2017)In the work with this Master thesis, expressions for the wavefunction overlap factor between eigenfunctions are obtained. These expressions should be suitable for numeric integration over the Brillouin zone, and are derived ... -
Can a meteor measure vertical winds?
(Master thesis, 2014)In the first part of this thesis the zonal and meridional tilt of the SKiYMET Meteor Radar at Dragvoll (63.4 N 10.5 E) has been found using two different methods. The average zenith angle model found the zonal tilt to be ... -
Can Local Stress Enhancement Induce Stability in Fracture Processes? Part I: Apparent Stability
(Journal article; Peer reviewed, 2019)By comparing the evolution of the local and equal load sharing fiber bundle models, we point out the paradoxical result that stresses seem to make the local load sharing model stable when the equal load sharing model is ... -
Can Local Stress Enhancement Induce Stability in Fracture Processes? Part II: The Shielding Effect
(Journal article; Peer reviewed, 2019)We use the local load sharing fiber bundle model to demonstrate a shielding effect where strong fibers protect weaker ones. This effect exists due to the local stress enhancement around broken fibers in the local load ... -
Carbon Dioxide Intercalation in Sodium Fluorohectorite Clay
(Master thesis, 2011)Wide angle X-ray Scattering (WAXS) measurements of the layered synthetic silicatesodium fluorohectorite (NaFh) when exposed to pressurized carbon dioxideare reported. With a custom made sample holder placed on top of a ... -
Carbonation of silica cement at high-temperature well conditions
(Journal article; Peer reviewed, 2019)Cements for well environments with temperatures above 110 °C are typically designed with silica additions. This is the case for many of the wells in the North Sea, which is a region promising for large-scale geological ... -
Carrier Scattering Rates in Zincblende Structure Semiconductors derived from 14 × 14 k · p and ab initio Pseudopotential Methods
(Master thesis, 2013)A set of programs for calculating carrier-phonon and carrier-alloy scat-tering rates have been constructed. Energy bands, gradients of the energy, second derivatives of the energy and eigenvectors of the carrier states ... -
Case study of a mesospheric wall event over Ferraz station, Antarctica (62 degrees S)
(Journal article; Peer reviewed, 2011)On 16–17 July 2007 during an observational campaign at Comandante Ferraz Antarctic Station (62° S, 58° W), a mesospheric wall was observed with an airglow all-sky imager. The wave appeared like an extensive dark region in ... -
