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 ... -
Fourier Transform Infrared Spectroscopy Combined with Partial Least Squared Regression and Standard Addition-Net Analyte Signal Method for Quantification of Chitin in Insect-based Fish Feeds
(Master thesis, 2018-10-25)Fourier transform infrared spectroscopy (FTIR) spectroscopy is a rapid and non-destructive technique applied with little or no sample preparation step. This work presents the use of FTIR spectroscopy combined with partial ... -
Free Fatty Acid Profiling of Metabolic Syndrome Blood Serum by Gas Chromatography-Mass Spectrometry
(Master thesis, 2015-09-10)It is estimated that 20-25% of adults in the world have metabolic syndrome (MetS), and in Chinese population this has become an important public health problem. MetS is characterized as cluster of metabolic disorders that ... -
From waste to bio-oil : Hydrothermal liquefaction of digested sewage sludge in small and large scale
(Doctoral thesis, 2023-06-16)FN’s bærekraftsmål er tydelige på hvilke tiltak som er nødvendige for å drastisk redusere de pågående klimaendringene i verden. Blant disse tiltakene finner man målet om bedre utnyttelse av bærekraftige råstoff, å sørge ... -
Functionalization of the Imidazole Backbone by Means of a Tailored and Optimized Oxidative Heck Cross-Coupling
(Journal article; Peer reviewed, 2020)A general and selective Pd-catalyzed cross-coupling of aromatic boronic acids with vinyl-imidazoles is disclosed. Unlike most cross-coupling reactions, this method operates well in absence of bases avoiding the formation ... -

Gas phase models of hydride transfer from divalent alkaline earth metals to CO2 and CH2O
(Journal article; Peer reviewed, 2023)The reactivity of HMg+, HMgCl, and HMgCl2− in hydride transfer reactions with CO2 and CH2O were studied by means of the reverse reactions—decarboxylation of HCO2MgCln+/0/− and deformylation of CH3OMgCln+/0/− (n = 0–2)—by ... -
Geometric Frustration on the Trillium Lattice in a Magnetic Metal-Organic Framework
(Journal article; Peer reviewed, 2022)In the dense metal-organic framework Na[Mn(HCOO)3], Mn2+ ions (S=52) occupy the nodes of a “trillium” net. We show that the system is strongly magnetically frustrated: the Néel transition is suppressed well below the ... -
Glioma Microstructure Modeling from Diffusion MRI: A Self-Supervised Deep Learning Approach
(Master thesis, 2023-06-02)Purpose: Gliomas are a highly heterogeneous group of primary brain tumors with poor prognosis, and treatment monitoring is challenging with its current diagnostic tool being invasive biopsy. In recent years, diffusion-weighted ... -
