Bubble evolution and anode surface properties in aluminium electrolysis
(Journal article, 2015)One significant contribution to the anodic potential during aluminum electrolysis is the formation of CO2 bubbles that screen the anode surface. This effect creates an additional ohmic resistance as well as an increased ... -
Bubble Evolution on Different Carbon Anode Designs in Cryolite Melt
(Peer reviewed; Journal article, 2020)The anode potential has been shown to be highly dependent on anode geometry and orientation in the Hall–Héroult process. This work is an experimental laboratory scale study of the effect of anode geometry and orientation ... -
Bubble Phenomena and Bubble Properties for Different Carbon Anodes in Cryolite Melt
(Doctoral theses at NTNU;2022:333, Doctoral thesis, 2022)This doctoral work is an experimental laboratory scale study of the effect of anode geometry, anode orientation and carbon anode material on bubble behavior and bubble properties in cryolite melt. The increased knowledge ... -
Bubble Phenomena and Bubble Properties for Horizontal and Vertical Carbon Anode Surfaces in Cryolite Melt Applying a See‐Through Cell
(Peer reviewed; Journal article, 2021)Gas bubble behavior on a carbon anode in a cryolite melt has been studied using a see-through cell. The phenomena studied have been growth, coalescence, detachment, and wetting during electrolysis. The surface orientation ... -
Bulk Metallic Glasses: Deformation and Design
(Doctoral theses at NTNU;2019:43, Doctoral thesis, 2019)Bulk metallic glasses are a group of alloys with amorphous atomic structure. When these alloys cool sufficiently fast, the atoms will “freeze” in the chaotic structure of the melt, rather than form crystals like most metals. ... -
Bulk Resistivity of Materials in the Si/FeSi Furnace
(Journal article; Peer reviewed, 2023)The formation of silicon carbide (SiC) and the energy distribution in the furnace are two important parameters in evaluating furnace operations. The energy distribution is determined by the resistivity of the materials in ... -
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 ... -
Bærekraftig Gjenvinning av Metaller fra Manganslam via Syreleaching
(Bachelor thesis, 2022)I oppgaven ble effekten av ulike forsøksparametere på metallutbyttet fra leaching av manganslam undersøkt. Det ble gjort ved å syreleache 13 prøver hvor noen av parameterne ble holdt like og noen ble variert. Tre forskjellige ... -
C-TiB2 Composite Inert Cathode Material by Spark Plasma Sintering
(Master thesis, 2018)TiB2 has been considered a potential inert, wettable cathode material for aluminum reduction cells for a long time. An important characteristic of TiB2 as a cathode material, is its excellent wetting properties towards ... -
Calcareous smectite clay as a pozzolanic alternative to kaolin
(Journal article; Peer reviewed, 2019)The hydration of cement pastes with addition of a kaolinite rich clay (Clay A) and a calcareous smectite rich clay (Clay B) was investigated with isothermal calorimetry, in-situ XRD, PXRD, TGA and EPMA. Portland cement was ... -
Calcination temperature dependent catalytic activity and stability of IrO2 – Ta2O5 anodes for oxygen evolution reaction in aqueous sulfate electrolytes
(Journal article; Peer reviewed, 2017)In this work, commercial IrO2-Ta2O5 anodes with a certain composition calcined at three different temperatures were investigated. The results show that the calcination temperature has a significant influence on the ... -
Capillary forces as a limiting factor for sawing of ultrathin silicon wafers by diamond multi-wire saw
(Peer reviewed; Journal article, 2020)Succeeding with ultrathin silicon wafer sawing by diamond multi-wire saw, is not only a matter of optimization; the challenges of thin wafer production and the capability limit have not yet been fully understood. In this ... -
Carbon Behaviour during Si Production
(Master thesis, 2013)First, the carbon content decreases with the increasing of silicon content in silicon phases. Second, the carbon content has no obvious trend in ferrosilicon phases. Third, the carbon element can be formed as silicon carbide ... -
Carbon Capture and Recovery by Molten Salts Electrochemistry
(Master thesis, 2022)To mitigate global warming and climate change, it is an urgent mission for us to reduce the amount of CO2 in the atmosphere. One of the viable solutions to this challenge may be to capture, and preferably, to recover CO2 ... -
