Experimental studies of clay-stabilized oil-in-water emulsions
(Master thesis, 2013)Several experiments concerning clay-stabilized Pickering emulsions have been studied.General emulsion coalescence with and without clay was investigated with optical microscopy.It showed that clay slows down the rate of ... -
Experimental Studies of Finger and Fracture Instabilities in Clays Throughout the Sol-Gel Transition
(Master thesis, 2011)This report concerns preliminary studies of fingering and fracturing in gelling materials, with the aim of identifying how the phenomena of fingering transitions into fracturing as the breaking medium gradually becomes ... -
Experimental Studies of Flow- and Electric Properties of Oil Droplets Including Suspended Clay Particles
(Master thesis, 2012)Experiments on oil droplets made of silicone oil and sodium-fluorohectorite (Na-Fh) clay particles suspended in castor oil were performed. The electric field (E-field)-induced structuring of clay particles placed inside ... -
Experimental Studies of Instabilities Near the Sol-Gel Transition
(Master thesis, 2012)This master thesis presents a new experimental way to dynamically determinerheological properties of a complex fluid. The fluid investigated is asuspension of the synthetic clay mineral laponite of 3 wt%. This is mixedtogether ... -
Experimental Studies of Monodisperse Pickering Emulsions Stabilized by Laponite Clay
(Master thesis, 2013)Experiments on oil-in-water Pickering emulsions stabilized by the disc-likesynthetic clay mineral Laponite were performed. Magnetic resonance imagingwas used to determine how the viscosity of the oil, the oil volume ... -
Experimental Studies of Self-organization from Electrically Polarized Clay Particles
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:279, Doctoral thesis, 2011) -
Experimental Studies of Smectite Clays: Colloids and Nanoporous Materials
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:215, Doctoral thesis, 2012)This thesis presents experimental work on two synthetic clay minerals: fluorohectorite and Laponite RD. Both are hectorite clays belonging to the widely studied smectite group of clays. The results presented can broadly ... -
Experimental Studies of the Two Phase Flow and Monodispersed Pickering Emulsions Stabilized by LaponiteRD in a Microfluidic T- Junction
(Master thesis, 2014)Monodispersed droplets were produced in a microfluidic T-junction by controlling flow rates of dispersed and continuous phases. The space between each droplet was controlled and it was similar between different droplets. ... -
Exploiting Coherence in Nonlinear Spin-Superfluid Transport
(Journal article; Peer reviewed, 2017)We show how the interference between superfluid spin currents can endow spin circuits with coherent logic functionality. While the hydrodynamic aspects of the linear-response collective spin transport obviate interference ... -
Exploiting infrasound to probe the dynamics of the middle atmosphere
(Doctoral theses at NTNU;2023:214, Doctoral thesis, 2023)This doctoral thesis examines the middle atmosphere (30 - 80 km altitude) using ground-based observations of low-frequency sound waves (infrasound). By exploiting infrasound waves, the thesis aims to increase observations ... -
Explorations of Coherent State Path Integral Formulations for Spin Systems Using a Projection Operator Implementation of Occupation Number Constraints
(Master thesis, 2021)I denne oppgaven utforsker vi hvordan en projeksjonsoperatormetode kan brukes til å implementere begrensninger i konsrtuksjonen av vegintegraler over koherente tilstander for spinnsystemer representert av Schwinger boson- ... -
Exploring avenus for compressed sensing in X-ray tomography
(Master thesis, 2018)In this paper different ways to reduce the amount of data associated with tomographic scans were explored. The L-BFGS algorithm was tested using a SIRT back-projection as its gradient. It showed faster and better convergence ... -
Exploring Biopolymers by the Fibre Bundle Model
(Master thesis, 2017)Bundles of polymeric chains in biological systems represent the analogue of macroscopic fibrous materials such as textile, wood or paper, scaled down to nanometric dimensions, and performing the same mechanical functions ... -
Exploring Electronic Confinement in Si:P δ-layers
(Master thesis, 2018)In this thesis, the electronic states of a quantum well system in silicon is investigated. The confinement is induced by a thin dopant profile called a delta-layer, creating an effective two-dimensional metallic region ... -
Exploring possibilities in AFM studies of InAs/GaAs QDs
(Master thesis, 2012)The main focus of this master thesis work has been to image InAs emph{quantum dots} (QDs) using emph{atomic force microscopy} (AFM), to identify and evaluate various image processing methods used to estimate the volume of ... -
