CO2 Gasification of Densified Biomass: The Influence of K on Reaction Rate
(Peer reviewed; Journal article, 2022)The Boudouard reactivity of metallurgical coke and densified charcoals was investigated in this study. Potassium is known to accumulate in ferromanganese furnaces and hence was evaluated as a catalyst of CO2 reactivity. ... -
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 ... -
Coalescence of Clean, Coated, and Decoated Aluminum for Various Salts, and Salt–Scrap Ratios
(Journal article, 2018)In a rotary furnace for aluminum recycling and dross treatment, a salt flux covers the molten metal to prevent new oxidation and to capture oxides, and impurities contained in the scrap. Furthermore, the salt must promote ... -
Coated Wooden Claddings and the Influence of Nanoparticles on the Weathering Performance
(Journal article; Peer reviewed, 2012)Accelerated climate aging experiments and cup measurements have been performed to investigate the effect of adding TiO2 nanoparticles and nanoclay to acrylic stain coatings against the influence of weathering. The coated ... -
Coatings with Antifouling Properties due to Graphene Oxide Addition
(Master thesis, 2019)Begroing er en utfordring for mange deler av industri, inkludert skipsfart, vannrensing og fiskeoppdrett. Bunnstoff har blitt brukt for å takle problemet siden det 17. århundre. Økologiske skader som følge av bruk av ... -
Coke Impurity Characterisation and Electrochemical Performance of Carbon Anodes for Aluminium Production
(Doctoral theses at NTNU;2019:352, Doctoral thesis, 2019)The aluminium production process uses consumable carbon anodes made from calcined petroleum cokes, recycled anode butts and coal tar pitch. The main ingredient is the coke, a side product from the petroleum refining industry. ... -
Cold Pressure Welding of Dissimilar Aluminum Alloys under Conditions Applicable to Hybrid Metal Extrusion & Bonding (HYB)
(Master thesis, 2014)Traditional solid-state welding methods mainly focuses on joining of similar materials.But with the increased interest in multi-material constructions more research is neededon joining of dissimilar materials. In the present ... -
Cold welding of steel and aluminum alloys - Joining processes, intermetallic phases and bond strength
(Doctoral theses at NTNU;2020:16, Doctoral thesis, 2020)Steel and aluminum are two of the most commonly used metals in today’s society and can be found everywhere, in vehicles, buildings, ships, and in most new electronic devices to name a few. Both metals have desirable ... -
Colloid-probe AFM studies of the surface functionality and adsorbed proteins on binary colloidal crystal layers
(Journal article; Peer reviewed, 2017)Colloid-probe-AFM has been widely used to measure the forces of interaction between two surfaces such as particles of different size and functionality or a flat surface and a particle in aqueous environments. However, the ... -
