Investigation of Transfection Using Silica-coated Cupric Oxide Nanowires
(Master thesis, 2013)One-dimensional high aspect ratio nanostructures grown from a copper foil are considered for intracellular delivery of bioactive molecules, such as drugs and genetic material. The cupric oxide (CuO) nanowires are coated ... -
Investigation of Two Immiscible Liquids Wetting at Elevated Temperature: Interaction Between Liquid FeMn Alloy and Liquid Slag
(Peer reviewed; Journal article, 2021)The goal of the current work is to develop a methodology to study the wetting behaviour of two immiscible liquids at high temperatures, and to investigate the parameters which influence the wetting properties. The wetting ... -
Investigation of Unoccupied Electronic Bands in Graphene
(Master thesis, 2018)In recent years, a lot attention has been paid to various two-dimensional materials due to their unique properties stemming from the spacial refinement of one of the material's dimensions. Regardless of the incredible ... -
Investigation on Quartz Crucibles for Monocrystalline Silicon Ingots for Solar Cells
(Master thesis, 2016)This thesis focuses on the bubble formation and growth in the quartz crucibles used to produce Czochralski (Cz) monocrystalline silicon ingots for solar cells production. Several experiments have been conducted to investigate ... -
An Investigation on Reduction of Calcium Added Bauxite Residue Pellets by Hydrogen and Iron Recovery through Physical Separation Methods
(Peer reviewed; Journal article, 2023)This study investigates the properties of H2-reduced calcium-added bauxite residue, self-hardened pellets, and the feasibility of iron recovery through electrostatic and magnetic separation methods. The oxide pellets are ... -
Investigation on scale formation in aluminium industry by means of a cold-finger
(Journal article; Peer reviewed, 2019)A cylindrical fouling probe or “cold-finger” has been used to investigate fouling from aluminium production off-gas. The probe was located upstream from the off-gas cleaning system. Surface deposits have been collected for ... -
Investigation on the Experimental Determination of Crude Oil in the Faeces from the Marine Copepod Calanus finmarchicus.
(Master thesis, 2012)Oil spilled into the ocean is subjected to weathering processes which alter the spilled or discharged oil. Natural dispersion is a weathering process which removes oil from the sea surface by breaking the oil into droplets. ... -
Investigations into 3-O-protected monosaccharides
(Master thesis, 2019)Følgende arbeid har som målsetting å tilrettelegge for totalsyntesen av 1-O-(3-O-linolenoyl-6-deoksy-6-sulfo-α-D-gluko-pyranosyl)glyserol (CDA), legemiddel med potent betennelsesdempende effekt. Med fokus på de tidligere ... -
Investigations into Lytic Polysaccharide Monooxygenase functionalities using NMR
(Doctoral theses at NTNU;2024:25, Doctoral thesis, 2024)English summary Lytic Polysaccharide Monooxygenases (LPMOs) are enigmatic enzymes that oxidatively depolymerize crystalline polysaccharides like cellulose and chitin. Following their discovery in 2010, LPMOs have gained ... -

The main intention of the work was to do investigations of mechanical ... -
Investigations of molybdenum-promoted manganese-based solid sorbents for H2S capture
(Peer reviewed; Journal article, 2020)The promotion effect of Mo-addition to alumina-supported Mn-based sorbents for high-temperature desulphurization was explored. A series of Mn-based sorbents with fixed Mn-loading and different Mo-loadings were prepared by ... -
Investigations of Pd3Au(100) as a catalytic model system
(Master thesis, 2018)Catalysts are defined as materials that lowers the activation energy of a reaction, without being consumed. In heterogeneous catalysis they are commonly transitions metals which have been refined to small particles using ... -
Investigations of PdAu membranes and model systems for production of pure hydrogen
(Master thesis, 2015)Hydrogen production from carbon-containing energy sources can capture the CO2 on site, and therefore reduce the contribution to global warming. The only emission when energy is produced through a fuel cell is H2O. Another ... -
