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 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
(Master thesis, 2022)Nanomaterialer er materialer med minst én dimensjon i milliarddelen av en meters rekkevidde (10-9 m). Betydelig forskning har blitt utført de siste to tiårene på utvikling og utvikling av magnetiske nanopartikler. Magnetiske ... -
Synthesis and Characterization of Gold and Copper Nanoparticles in Mesoporous Frameworks
(Master thesis, 2012)In this thesis, the mesoporous materials SBA-15 and Al-SBA-15 have been synthesized and characterized. In addition, syntheses of mesoporous AlPO and SAPO have been investigated. SAPO was successfully synthesized, while ... -
Synthesis and Characterization of Halogen Substituted 1,2,4-Triazolobenzodiazepines and Their α-Hydroxylated Metabolites
(Master thesis, 2022)Målet med denne masteroppgaven er å effektivt syntetisere seks ulike triazolobenzodiazepiner (7) og deres α-hydroksylerte metabolitter (6) fra det korresponderende benzofenonet (1), med fokus på triazolobenzodiazepinene ... -
Synthesis and characterization of hybrid aminopropyl silane-based coatings on stainless steel substrates
(Journal article; Peer reviewed, 2014)Transparent and homogeneous hybrid aminopropyl silane-based coatings on steel were prepared by the sol–gel method using hydrolyzed γ-APS as a precursor. The coatings were fabricated by dip coating, and the effect of pH, ... -
Synthesis and Characterization of Hydrogen Transport Membranes
(Master thesis, 2012)Hydrogen transport membranes have gained interest from industry as an alternative to pressure swing adsorption or cryogenic distillation, and are aimed to reduce cost, equipment size, energy consumption and waste generation. ... -
