Recycling of paper, cardboard and its PFAS in Norway
(Peer reviewed; Journal article, 2023)Per- and polyfluoroalkyl substances (PFAS) have been used in paper products since the 1960s. PFAS emissions during the life cycle of these products have been substantial sources of these substances to the environment. Here, ... -
Reduced orbital space coupled cluster calculations using a multilevel Hartree-Fock wave function
(Master thesis, 2017)Embedding, or multilevel, schemes have become exceedingly popular in recent years. The idea is to divide the system into an active part, which is treated by an accurate quantum mechanical method, and then treat the rest ... -

Regioselective Azide-Alkyne Cycloaddition Towards Functionalized 1,2,3-Triazoles
(Bachelor thesis, 2024)Denne teoretiske litteraturgjennomgangen beskriver de ulike azid-alkyn-cykloadisjonsreaksjonene (AAC) og belyser deres styrker og begrensninger. AAC er en enkel måte å fremstille 1,2,3-triazolringer på, og er mye brukt i ... -
Regioselective Preparation of 1,2,3-Triazoles for Bioactive Studies Based on Marine Bioprospecting
(Master thesis, 2015)The azides 1d and 1c were prepared using literature procedures. The azides serve as starting materials in copper- and ruthenium-catalyzed 1,3-dipolar dipolar cycloadditions to N-protected alkynes 2a and 2b, to afford ... -
Regioselective Protection and Functionalization of C-6 in The Synthesis Towards Sulfoquinovoses
(Master thesis, 2018)The main goal of this thesis was to explore and compare two protection strategies yielding 2,3,4-tri-O-benzyl-α-D-glucopyranosides. Further work was done to functionalize the primary 6- hydroxyl position to a sulfonic acid ... -
Regioselectivity in the thermal rearrangement of unsymmetrical 4-methyl-4H-1,2,4-triazoles to 1-methyl-1H-1,2,4-triazoles
(Journal article; Peer reviewed, 2001)The rearrangement of 4-methyl-3,5-diaryl-4H-1,2,4-triazoles to the corresponding 1-methyl-3,5-diaryl-1H-1,2,4-triazoles showed regioselectivity comparable to that observed for the alkylation of 3,5-diaryl-1H-1,2,4-triazoles. ... -
Releases of oily produced water from offshore installations - A combined laboratory and modelling study comparing resulting surface oil slicks and oil slicks detected by satellite
(Master thesis, 2021)Produsertvann er et biprodukt fra petroleumsindustrien som blir sett på som avfall, og blir ført opp til overflaten sammen med olje og gass. Etter at produsertvannet har gått gjennom nødvendige renseprosesser på oljeplattformen ... -
Removal of Amorphous Carbon and Transition Metal Impurities from Carbon Nanofibers at an Industrial Scale
(Bachelor thesis, 2021)Carbon nanotubes has been a hot topic in the last 30 years as "the future material of manufacturing and electronic compounds". Besides this, the world is under high distress trying to abate the climatic effects of greenhouse ... -
Resolving the Notorious Case of Conical Intersections for Coupled Cluster Dynamics
(Journal article; Peer reviewed, 2017)The motion of electrons and nuclei in photochemical events often involves conical intersections, or degeneracies between electronic states. They serve as funnels in nuclear relaxation processes where the electrons and ... -
Response Theory Based Methods for Electronic Transport
(Master thesis, 2021)Nanoelektronikk er er fagfelt som blir mer og mer relevant nå som elektronikk blir mindre og raskere, og med rask utvikling av teknologier som superledere og kvantedatamaskiner. Dette er et forskningsfelt der det har vært ... -
Responses in the bacterial community structure to waste nutrients from aquaculture: an in situ microcosm experiment in a Chilean fjord
(Journal article; Peer reviewed, 2017)Chilean salmon farms release inorganic nutrients excreted by the fish into the surrounding water in Patagonian fjords. The objective of this experiment from the Comau Fjord (42.2° S) in southern Chile was to study how ... -
Responses in the microbial food web to increased rates of nutrient supply in a southern Chilean fjord: Possible implications of cage aquaculture
