Synthesis and Characterisation of Co-based Fischer-Tropsch Catalysts and Supports, using hydrothermal and chemical attrition Method - The magnesium moderation Effect
(Master thesis, 2011)Magnesium modification at different calcination temperatures of γ-alumina supports for cobalt Fischer-Tropsch catalysts was investigated. Support modification and catalyst preparation were performed by applying the incipient ... -
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 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 Tungsten Carbide
(Master thesis, 2016)From the very early stage of human civilization tungsten carbide is used as the hard metal in geoengineering for producing drill buttons and other wear resistance parts. However due to its limited storage in earth as well ... -
Synthesis and design strategies of CuCr-layered double hydroxides for improved photocatalytic nitrogen fixation under visible light
(Master thesis, 2021)Ammonia is one of the most important chemical commodities in the world. The synthesis of this substance currently relies on the Haber Bosch process, which is a very energy-intensive process. Due to its importance and ... -
Synthesis and Evaluation of Imidazopyridinones, Pyrrolopyrimidines and Tetrahydrocarbazoles as Antibacterial Agents
(Doctoral theses at NTNU;2024:129, Doctoral thesis, 2024)Mankind is in a continual arms race against bacteria, as we develop new antibiotics whilst the bacteria develop resistance against them. The need to produce novel antibiotics is now dire, as most new commercial antibiotics ... -
Synthesis and in vitro cellular interactions of superparamagnetic iron nanoparticles with a crystalline gold shell
(Journal article; Peer reviewed, 2014)Fe@Au core–shell nanoparticles (NPs) exhibit multiple functionalities enabling their effective use in applications such as medical imaging and drug delivery. In this work, a novel synthetic method was developed and optimized ... -
Synthesis of Carbon Nanofibers and Carbon Nanotubes
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:18, Doctoral thesis, 2005)Carbon nanofibers (CNFs) and carbon nanotubes (CNTs) have attracted intense research efforts with the expectation that these materials may have many unique properties and potential applications. The most promising way for ... -
Synthesis of Composite Nanoparticles with Magnetic Properties
(Master thesis, 2013)There is a lot of research being done in inorganic nanoparticles for use in biomedicine as magnetic resonance imaging contrast-agents, where especially gadolinium is very interesting because of its 7 unpaired electrons. ... -
Synthesis of Crosslinked PEG/IL Blend Membrane via One-Pot Thiol–Ene/Epoxy Chemistry
(Journal article, 2020)Poly(ethylene glycol) (PEG)-based membranes have obtained considerable attentions for CO2 separation for their promising CO2 separation performance and excellent thermal/ chemical resistance. In this work, a one-pot ... -

Synthesis of Fischer-Tropsch Catalysts in an Autoclave System
(Master thesis, 2012)12- or 18 wt.% cobalt and 0.5 wt.% rhenium was impregnated on nickel-aluminate spinel support supplied by Statoil R&D. The catalysts were dried in an autoclave continuous stirred tank reactor with different reactor parameters. ... -
Synthesis of Fuels from Biomass Derived Oxygenates
(Master thesis, 2013)Direct conversion of wooden biomass to liquid fuels is performed in two-step process. First step is to transform cellulose, hemicelluloses and lignin into to basic chemical compounds which they are assembled of (mainly ... -
Synthesis of high-temperature solid sorbents for CO2 capture
(Master thesis, 2018)The use of fossil fuels have escalated since the first industrial applications at the mid 19th century with a consequence of increased emissions of carbon dioxide and other green house gases. As a result, the global climate ... -
