Synergy between chemical demulsification and electrocoalescence: From bench to large scale
(Doctoral theses at NTNU;2020:64, Doctoral thesis, 2020)Production of crude oil from reservoirs always contain additional fluids, namely formation water and gas that occur naturally below the surface or seabed. Especially problematic is the water that becomes dispersed within ... -
Synergy Effects between Polyethylene and high Density Papers in Gas Barrier Materials - a Morphological Study
(Dr. ingeniøravhandling, 0809-103X; 2002:39, Doctoral thesis, 2002)This work has its origin in efforts to optimise the barrier properties of packaging materials in which polyethylene extrusion coated high-density paper constitute the oxygen barrier. Examples of applications where this ... -
Syngas production from dry methane reforming over yttrium-promoted nickel-KIT-6 catalysts
(Journal article; Peer reviewed, 2018)Dry reforming of methane was studied over Ni,Y-promoted KIT-6 ordered mesoporous silicas, prepared by incipient impregnation (nickel content 12 wt%, yttrium content of 4 wt%, 8 wt% or 12 wt%). The catalysts were characterized ... -
Synthesis and applications of carbon nanomaterials: from quanta dots to microspheres
(Master thesis, 2017)In this work, activated carbon fibers and activated carbon spheres were pre- pared through physical activation with CO2 and steam. The precursors used were polyaniline (PANI) and resorcinol-formaldehyde polymer spheres (RF ... -
Synthesis and Carboxyl-Functionalization of Iron Oxide Nanoparticles for Diagnostics
(Master thesis, 2022)De siste tiårene har det vært en kraftig økning i omfanget av forskning på nanopartikler av jernoksid, på grunn av dets anvendelse i flere potensielle applikasjoner innenfor ulike fagfelt, som blant annet biomedisin, ... -
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 ... -
