SAPO-34 with Copper: Investigation of hierarchical pore characteristics and interactions with copper for catalytic applications
(Master thesis, 2014)Hierarchical SAPO-34 was produced using the dry gel conversion method, where an amorphous, mesoporous silicoaluminophosphate was subjected to steam treatment with the presence of organic template. This resulted in a ... -
Saturation of radiative heat transfer due to many-body thermalization
(Peer reviewed; Journal article, 2020)Radiative heat transfer between two bodies saturates at very short separation distances due to the nonlocal optical response of the materials. In this work, we show that the presence of radiative interactions with a third ... -
Scalable Fabrication of Metallic Nanogaps at the Sub-10 nm Level

Scaling factors for channel width variations in tree-like flow field patterns for polymer electrolyte membrane fuel cells - An experimental study
(Peer reviewed; Journal article, 2021)To have a uniform distribution of reactants is an advantage to a fuel cell. We report results for such a distributor with tree-like flow field plates (FFP). Numerical simulations have shown that the width scaling parameters ... -
Screening analyses of pinosylvin stilbenes, resin acids and lignans in Norwegian conifers
(Journal article; Peer reviewed, 2006)The content and distribution of stilbenes and resin acids in Scots pine (Pinus sylvestris) and spruce (Picea abies), sampled in central Norway, have been examined. The contents of pinosylvin stilbenes in pine heartwood/living ... -
Screening and characterisation of CdTe/CdS quantum dot-binding peptides for material surface functionalisation
(Peer reviewed; Journal article, 2020)Quantum dots (QDs) are promising nanomaterials due to their unique photophysical properties. For them to be useful in biological applications, the particle surface generally needs to be conjugated to biological molecules, ... -
Screening of Inhibitors for Amine Degradation
(Master thesis, 2012)Hindering the degradation of amines in the CO2-capturing process is important both for economical purposes when it comes to loss of solvent and impacts on the process, and to prevent emissions of volatile degradation ... -
Seasonal biogeochemical cycling of mercury on the Arctic Ocean shelf
(Doctoral theses at NTNU;2023:286, Doctoral thesis, 2023)The toxic pollutant mercury accumulates in marine food webs on a global scale, with consumption of seafood as the primary exposure pathway for humans. Since 2017, the Minamata Convention on Mercury has aimed to reduce human ... -
Seasonal variation in chemical composition and contaminants in European plaice (Pleuronectes Platessa) originated from the west-coast of Norway
(Peer reviewed; Journal article, 2022)The seasonal effect on chemical composition and contaminants in European plaice (Pleuronectes platessa) captured in Norwegian waters was investigated in three seasons (September, December, April). Fillets were compared by ... -
Seebeck and Peltier coefficients of hydrogen electrodes related to the PEMFC
(Master thesis, 2012)The coefficient of Thermoelectric power of hydrogen electrode as function of partial pressure has shownto be negative in accordance with the negative sign of state function of entropy with a deviation of almost halfits ... -
Seebeck coefficients of cells with lithium carbonate and gas electrodes
(Journal article; Peer reviewed, 2015)The Seebeck coefficient is reported for thermoelectric cells with gas electrodes and a molten electrolyte of one salt, lithium carbonate, at an average temperature of 750 °C. We show that the coefficient, which is 0.88 mV ... -
Seebeck coefficients of cells with molten carbonates relevant for the metallurgical industry
(Journal article; Peer reviewed, 2015)We report Seebeck coefficients of electrochemical cells with molten carbonate mixtures as electrolytes and carbon dioxide|oxygen electrodes. The system is relevant for use of waste heat and off-gases with concentration of ... -
Seebeck, Peltier, and Soret effects: On different formalisms for transport equations in thermogalvanic cells
(Peer reviewed; Journal article, 2023)Thermogalvanic cells convert waste heat directly to electric work. There is an abundance of waste heat in the world and thermogalvanic cells may be underused. We discuss theoretical tools that can help us understand and ... -
Seeding as a start-up strategy for improving the acclimation of freshwater nitrifying bioreactors to salinity stress
(Peer reviewed; Journal article, 2021)Recirculating aquaculture systems (RAS) for anadromous fish such as salmonids often require salinity changes during the production cycle. However, high or variable salinity can disrupt the biological nitrification process, ... -
Seeking minimum entropy production for a tree-like flow-field in a fuel cell
