Investigation of the Red Zone of Multicrystalline Silicon Ingots for Solar Cells
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:184, Doctoral thesis, 2012)This thesis is dealing with the “Red Zone” of multicrystalline silicon (mc-Si) ingots, a region which exhibits low performances and which is usually removed before slicing the wafers for solar cells fabrication. It is ... -
Investigation of Two Immiscible Liquids Wetting at Elevated Temperature: Interaction Between Liquid FeMn Alloy and Liquid Slag
(Peer reviewed; Journal article, 2021)The goal of the current work is to develop a methodology to study the wetting behaviour of two immiscible liquids at high temperatures, and to investigate the parameters which influence the wetting properties. The wetting ... -
Investigation on Quartz Crucibles for Monocrystalline Silicon Ingots for Solar Cells
(Master thesis, 2016)This thesis focuses on the bubble formation and growth in the quartz crucibles used to produce Czochralski (Cz) monocrystalline silicon ingots for solar cells production. Several experiments have been conducted to investigate ... -
An Investigation on Reduction of Calcium Added Bauxite Residue Pellets by Hydrogen and Iron Recovery through Physical Separation Methods
(Peer reviewed; Journal article, 2023)This study investigates the properties of H2-reduced calcium-added bauxite residue, self-hardened pellets, and the feasibility of iron recovery through electrostatic and magnetic separation methods. The oxide pellets are ... -
Investigation on scale formation in aluminium industry by means of a cold-finger
(Journal article; Peer reviewed, 2019)A cylindrical fouling probe or “cold-finger” has been used to investigate fouling from aluminium production off-gas. The probe was located upstream from the off-gas cleaning system. Surface deposits have been collected for ... -
An Invitation on Characterization of H<inf>2</inf>-Reduced Bauxite Residue and Recovering Iron through Wet Magnetic Separation Processes
(Peer reviewed; Journal article, 2023)Recovering iron from the bauxite residue (BR) is one of the long-standing challenges in the mining industry. However, there is a substantial lack of information in the literature regarding sample properties and iron ... -
Ionic Conductivity Measurements in Aqueous and Molten Salt Electrolytes
(Bachelor thesis, 2023)I en tid med stort fokus på det grønne skiftet, står aluminiumsindustrien overfor en sentral utfordring knyttet til mer klimavennlig aluminiumsproduksjon. Alcoas klorid- og elektrolyseprosess er et alternativ som kan bidra ... -
Ionomer content optimization in nickel-iron-based anodes with and without ceria for anion exchange membrane water electrolysis
(Journal article; Peer reviewed, 2021)Hydrogen production from anion exchange membrane water electrolysis (AEMWE) is an efficient cost-effective solution to renewable energy storage. Contrary to proton exchange membrane (PEM) electrolysis, AEMWE requires further ... -
Ir based catalysts for PEM water electrolysis prepared via galvanic displacement
(Doctoral theses at NTNU;2021:187, Doctoral thesis, 2021)In the transition away from non-renewable energy sources, the use of fluctuating power sources such as wind and solar are increasing. This creates a need for temporary storage of excess energy when production exceeds demand. ... -
Iridium-based Electrocatalysts for the Oxygen Evolution Reaction
(Doctoral thesis at NTNU;2016:226, Doctoral thesis, 2016)English version: This thesis covers several topics related to the anodic catalyst for the oxygen evolution reaction (OER) in polymer electrolyte membrane (PEM) water electrolysis. Water electrolysis is considered one ... -
