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 ... -
Functional in vitro diversity of an intrinsically disordered plant protein during freeze–thawing is encoded by its structural plasticity
(Journal article; Peer reviewed, 2024)Intrinsically disordered late embryogenesis abundant (LEA) proteins play a central role in the tolerance of plants and other organisms to dehydration brought upon, for example, by freezing temperatures, high salt concentration, ... -
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 Chromatography optimization using experimental design and surface response methodology.
(Master thesis, 2018-10-25)Gas Chromatography (GC) is an analytical method for the separation of enormous range of routine applications, to analyse very complex mixtures of Petroleum, such us different proteins in the human body, and natural products. ... -
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 ... -
GLORY: Generator of the structures of likely cytochrome P450 metabolites based on predicted sites of metabolism
(Peer reviewed; Journal article, 2019-06-12)Computational prediction of xenobiotic metabolism can provide valuable information to guide the development of drugs, cosmetics, agrochemicals, and other chemical entities. We have previously developed FAME 2, an effective ... -
GRANADA consensus on analytical approaches to assess associations with accelerometer-determined physical behaviours (physical activity, sedentary behaviour and sleep) in epidemiological studies
(Journal article; Peer reviewed, 2021)The inter-relationship between physical activity, sedentary behaviour and sleep (collectively defined as physical behaviours) is of interest to researchers from different fields. Each of these physical behaviours has been ... -
