Synthesis and Characterisation of the Plastic Crystal Solid Solution Systems [(CH3)4N]x[(CH3CH2)4N]1-x[FeBrCl3] (x = 0.7 - 1)
(Master thesis, 2021)Gjennom deres reversible permanente polarisering har ferroelektriske materialer funnet bruksområder innen flere grener av teknologi, som for eksempel digitalt minne, filtre eller sensorer. Dagens konvensjonelle ferroelektriske ... -
Synthesis and characterisation of tungsten carbide
(Master thesis, 2015)The supply of tungsten carbide is very limited, which has resulted in EU categorizing tungsten as a critical raw material. Instead of substituting tungsten entirely, this paper has looked into the possibility of using SiC ... -
Synthesis and characterization of (111)- oriented perovskite oxide heterostrctures
(Doctoral theses at NTNU;2019:14, Doctoral thesis, 2019)The limits of silicon in semiconductor devices are fast approaching, with feature sizes reaching the realm where quantum effects start to dominate. A promising approach is to include materials with new functionality such ... -
Synthesis and characterization of (111)-oriented BaTiO3 thin films
(Journal article; Peer reviewed, 2019)The synthesis of (111)-oriented BaTiO3 thin films on Nb-doped SrTiO3 and bilayers of BaTiO3 and La0.7Sr0.3MnO3 on SrTiO3 are investigated. With increasing thickness the films are found to exhibit a decreasing out-of-plane ... -
Synthesis and Characterization of 12CaO·7Al2O3 Slags: The Effects of Impurities and Atmospheres on the Phase Relations
(Journal article; Peer reviewed, 2020)Synthesis of crystalline slags of 12CaO·7Al2O3 phase from the corresponding melt compositions in different atmospheric conditions and different purities is investigated. Observations using a thermogravimetry coupled with ... -
Synthesis and characterization of a new phenothiazine dye for use in dye sensitized solar cells
(Master thesis, 2021)Kombinasjonen av et økende globalt energibehov og raske negative endringer i klimaet, gjør at det haster å erstatte fossilt brensel med fornybare energikilder. De siste tiårene har investeringer i solcelleteknologi økt ... -
Synthesis and Characterization of Bismuth-containing Nanomaterials for Photocatalytic Ammonia Synthesis
(Master thesis, 2019)Å utvikle en miljøvennlig og mindre energikrevende metode for å fremstille ammoniakk er nødvendig for å bidra til en bærekraftig utvikling og redusere den globale oppvarmingen. Dagens amoniakkproduksjon er basert på naturgass ... -
Synthesis and Characterization of BODIPY Dyes for Optoelectronic Applications
(Master thesis, 2019)Målet for dette masterprosjektet var å syntetisere nye kromoforer basert på bor dipyrrometen difluorid (F-BODIPY) kromoforen. Reaksjonsruten mot de ønskede kromoforene er vist i skjema 2. De ferdige fargestoffene skulle ... -
Synthesis and Characterization of CeO2- and LaNbO4-based Ionic Conductors
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:181, Doctoral thesis, 2006)Ceramic electrolytes that conduct either oxygen ions or protons at intermediate temperatures are important materials for use in e.g. solid oxide fuel cells, the prime candidate to produce electricity by electrochemical ... -
Synthesis and Characterization of Chitosan Coated Iron Oxide Nanoparticles for Biomedical Applications
