Cation inter-diffusion and formation of intermediate phases in CoO and La2NiO4+d diffusion couples.
(Peer reviewed; Journal article, 2022)Cation interdiffusion between La2NiO4+δ (LN) and CoO diffusion couples was investigated by thermal annealing in ambient air at 1200 °C for 48 and 168 h, and analysis of the cross sections by scanning electron microscopy ... -
Cation Nonstoichiometry of La2CoO4
(Master thesis, 2017)In this thesis, the cation nonstoichiometry and composition range of the La2CoO4 phase in the La-Co-O system were investigated and compared to earlier studies. There is a controversy over the cation nonstoichiometry of ... -
Cell Performance Comparison between C14- and C15-Predomiated AB2 Metal Hydride Alloys
(Journal article, 2017)The performance of cylindrical cells made from negative electrode active materials of two selected AB2 metal hydride chemistries with different dominating Laves phases (C14 vs. C15) were compared. Cells made from Alloy C15 ... -
Cellulosebaserte membraner i vanadium strømningsbatteri
(Bachelor thesis, 2023)Ettersom bruken av intermitterende energikilder har økt de siste årene, har behovet for å kunne lagre denne energien til senere bruk også økt. For å kunne oppnå dette har utvikling av nye batteriteknologier eksplodert i ... -
Centrosymmetric Tetragonal Tungsten Bronzes A4Bi2Nb10O30 (A = 2 Na, K, Rb) with a Bi 6s Lone Pair
(Peer reviewed; Journal article, 2022)A first-principles study of the tetragonal tungsten bronze (TTB) K4Bi2Nb10O30 has suggested that the Bi 6s lone pair causes in-plane polarization (within the a–b plane), corresponding to the one found in Pb5Nb10O30 (PN), ... -
Ceramic Foam Filters (CFFs) for Aluminium Melt Filtration - Stability, Compression, and Performance
(Doctoral theses at NTNU;2022:260, Doctoral thesis, 2022)During aluminium production, the molten aluminium will necessarily include a certain amount of impurities, including non-metallic inclusions, i.e., solid objects immersed in the melt. These inclusions are known to be ... -
Ceramic matrix composites based on silicon carbide and carbon fibers
(Master thesis, 2019)Silisiumkarbid er velkjent for sine gode mekaniske og termiske egenskaper, som gir det et bredt spekter av industrielle anvendelser. SiC er imidlertid en sprø keramikk, og selv de minste sprekker kan vise seg katastrofale. ... -
Ceramic Thermal Barrier Coatings of Yttria Stabilized Zirconia Made by Spray Pyrolysis
(Master thesis, 2011)A thermal barrier coating (TBC) is used as thermal protection of metallic components exposed to hot gas streams in e.g. gas turbine engines. Due to a high thermal expansion coefficient, low thermal conductivity, chemical- ... -
CFD Modeling of boron removal from liquid silicon with cold gases and plasma
(Journal article; Peer reviewed, 2018)The present study focuses on a specific step of the metallurgical path of purification to provide solar-grade silicon: the removal of boron through the injection of H2O(g)-H2(g)-Ar(g) (cold gas process) or of Ar-H2-O2 ... -
CFD Modelling of Alumina Feeding
(Journal article, 2018)The dissolution and distribution of alumina in molten cryolite bath is a complex process, involving heat and mass transfer, phase transition and dynamics for a particle population with variable size and properties. Although ... -
CFD Study on Continuous Tapping of Silicon
(Peer reviewed; Journal article, 2022)Silicon is mostly produced in rotating submerged arc furnaces with continuous tapping of metal. The burden is often dense due to condensates. Thus, furnace gas does not escape easily to the top of the burden and some gas ... -
