Numerical simulation of continuum scale electrochemical hydrogen bubble evolution
(Peer reviewed; Journal article, 2021)One of the important aspects in improving the efficiency of electrochemical processes, such as water electrolysis, is the efficient removal of bubbles which evolve from the electrodes. Numerical modelling based on Computational ... -
Effect of Mg content in the La3-xMgxNi9 battery anode alloys on the structural, hydrogen storage and electrochemical properties
(Peer reviewed; Journal article, 2021)The present work is focused on the studies of structure, hydrogen storage and electrochemical properties of the La3-xMgxNi9 (x = 1.0, 1.1 and 1.2) alloys as active materials of negative electrodes in the Nickel-Metal Hydride ... -
Structures and Role of the Intermediate Phases on the Crystallization of BaTiO3 from an Aqueous Synthesis Route
(Peer reviewed; Journal article, 2021)Carbonate formation is a prevailing challenge in synthesis of BaTiO3, especially through wet chemical synthesis routes. In this work, we report the phase evolution during thermal annealing of an aqueous BaTiO3 precursor ... -
On Gaseous Emissions During Alumina Feeding
(Peer reviewed; Journal article, 2021)Aluminium electrolysis involves feeding of alumina into a cryolite-based bath. Water originating from alumina as well as from air reacts with fluorides and results in HF evolution. Untreated HF gas is a significant ... -
Electrochemical activation of a diatom-derived SiO<inf>2</inf>/C composite anode and its implementation in a lithium ion battery
(Peer reviewed; Journal article, 2021)Nano-architectured silica is extracted from algae harvested in the ocean. Its electrochemical properties are investigated as an anode material for lithium ion batteries. The beneficial effect of a carbon coating formed by ... -

Dispersion and dissolution of alumina in cryolite melts: impact of sulfur and carbon on dissolution behavior in see through cell
(Master thesis, 2021)Aluminium blir produsert industrielt ved hjelp av Hall-Herôult metoden. Denne metoden produserer flytende aluminium fra aluminiumoksid (kalt alumina) og karbon i ett bad med flytende kryolitt. Denne prosessen krever høy ... -
Characterizing the damage mechanisms of orthopedic joint prostheses
(Master thesis, 2021)Dette prosjektet undersøkte tre brukte hofteleddsproteser med hensikt å forstå hvilke skademekanismer som var til stede og hvorfor disse oppsto. En rekke metallurgiske undersøkelser ble benyttet for å avdekke overflateka ... -
Phase relations and thermomechanical properties of (Gd2Zr2O7)1-x(YbSZ)x based thermal barrier coatings (0 ≤x≤ 0.98)
(Peer reviewed; Journal article, 2021)Doped Gd2Zr2O7 materials have interesting properties as thermal barrier coatings (TBC) to replace the YSZ topcoats traditionally used. Here we investigate the thermomechanical properties and phase relations of Gd2Zr2O7 ... -
Valorization of SiMn Sludge for Production of Low-Phosphorus Ferroalloys
(Journal article; Peer reviewed, 2021)The sludge generated by wet scrubbing the off-gas from a silicomanganese plant in Norway represents a significant loss in silicon and manganese values. This work seeks to extract these values in the production of ferroalloys ... -

DFT study of MXenes
(Master thesis, 2021)The development of Rechargable Magnesium Batteries (RMB) has been an active area of research over the past decades, and is a promising alternative to state-of-the art Li-ion batteries. It is promising because it could offer ... -
In situ high temperature spectroscopic study of liquid inclusions and hydroxyl groups in high purity natural quartz
(Peer reviewed; Journal article, 2021)High purity natural based quartz is used as raw material for production of crucibles for solar-grade silicon production. The crucible properties are strongly related to presence of water and hydroxyl groups in the raw ... -
Synthesis of a graphitic carbon nitride electrode for hydrogen production by photoelectrolysis of water and ultrasound deposition of nanoparticles
(Master thesis, 2021)Dette prosjektet tar sikte på å produsere hydrogengass fra vann ved hjelp av solstråling for å gi en fornybar energibærer. For å gjøre det, ble en grafittisk karbonnitridelektrode produsert og syntetisert i en enkel ettrinns ... -
CO2-Free Aluminium Production: Production of AlCl3 by Carbochlorination of Bauxite
(Master thesis, 2021)Den kommersielle produksjonen av primær Al er avhengig av to energiintensive prosesser fra slutten av 1800-tallet: Bayer og Hall-Héroult prosessen. Store direkte CO2-utslipp er knyttet til sistnevnte, og med oppmerksomheten ... -
Comparison of Cleaning Routines in Norwegian Swimming Pools
(Bachelor thesis, 2021)Forskrift for badeanlegg, bassengbad og badstu m.v. gir lite veiledning n˚ar det kommer til rengjøring av overflater. Det varme og fuktige miljøet i svømmehaller er ideelt for vekst av bakterier. I denne oppgaven ble det ... -
The Interactions Between Oxide Film Inclusions and Inoculation Particles TiB2 in Aluminum Melt
(Peer reviewed; Journal article, 2021)In this work, a systematic study on the interactions between aluminum oxide films and TiB2 grain refiner particles and their effect on grain refinement behavior have been conducted. Oxide f ilms were introduced into a ... -
