(Master thesis, 2018-06-28)The purpose of this project has been to determine the fat content, fat distribution and fatty acid composition in wild and farmed salmon using solid-state Nuclear Magnetic Resonance (NMR) spectroscopy and Magnetic Resonance ... -
Fishmeal physicochemical properties. Impact on the fish feed extrusion process, phase transitions and physical pellet quality
(Doctoral thesis, 2015-06-19)Norway is the world largest producer of Atlantic salmon (Salmo salar). In 2013 the Norwegian aquaculture industry produced 1.2 million metric tons salmon with the use of 1.5 million metric tons of commercial feeds. The ... -
Fixed Bed Reactor Validation of a Mayenite Based Combined Calcium–Copper Material for Hydrogen Production through Ca–Cu Looping
(Peer reviewed; Journal article, 2019-07-15)For the first time, a mayenite based material combining calcium and copper (18.0/37.6/44.4 estimated active wt % CaO/CuO/Ca12Al14O33, CuO/CaO = 2.1 [wt/wt]) has been subjected to three full calcium–copper chemical looping ... -
Formation and Growth of Clusters of Sulfur Dioxide
(Peer reviewed; Journal article, 2015-06-01)Formation and growth of neutral SO2 clusters is investigated in an adiabatic-expansion setup by means of sulfur 2p (S2p) photoelectron spectroscopy and theoretical modeling. The shift in S2p ionization energy between the ... -
Formation of an Isomeric Mixture of Dienynes Instead of a Diallene
(Journal article, 2020)Attempts to convert 1,1,2,2,7,7,8,8-octaethoxyocta-3,5-diyne to a symmetric allene by reduction with lithium aluminum hydride failed. Instead reduction accompanied by isomerization occurred and afforded 1,1,2,7,8,8-hexae ... -
Formic acid aided catalytic lignin conversion in ethanol and water media
(Doctoral thesis, 2016-12-21)The viability of future lignocellulosic bio-refineries is highly dependent on the efficient conversion of the lignin component. A promising and relatively new lignin conversion methodology is the Lignin-to-Liquid (LtL) ... -
Formic acid assisted liquefaction of lignin in water and ethanol, investigated for a 0.025 and a 5 L batch reactor: Comparison of yields and compositions of the products
(Peer reviewed; Journal article, 2019)Formic acid assisted conversion of lignin to liquids (LtL-process), where lignin is hydrodeoxygenated in a one-step conversion, produces bio-oils with a molecular weight range of 300–600 Da that comprise a complex mixture ... -
Forsøk på syntese av imidazol-2-yliden baserte sølvkomplekser med hydrofile 4-(5)-sidekjeder
(Master thesis, 2010-05-31)Sølvets bakteriedrepende egenskaper har vært kjent siden antikken og sølv har vært utnyttet som sårbehandler helt inn i moderne tider. Utviklingen av sølvpreparater har vært lang og inkluderer sølvobjekter og salter til ... -
