Studies on Gold-Nitrone Chemistry
(Master thesis, 2017)The gold(I)-nitrone catalysed cyclotrimerization of diaryl propargyl acetals was studied. Gold(I)-nitrone and gold(I)/gold(III)-oxadiazole complexes were also synthesised. -
Studies on gold-nitrone systems
(Journal article; Peer reviewed, 2019)Novel Au(I)-nitrone complexes with specific catalytic properties were prepd. Also, Au(I)- and Au(III)-oxadiazole complexes were formed by a novel Au-generated nitrile-nitrone [3 + 2] cycloaddn., and the crystal ... -
Study of Long Range Transported Pollutants in Arctic Soil
(Master thesis, 2017)In this master thesis, levels of Polychlorinated Biphenyls (PCBs), total organic carbon (TOC) and potentially long range transported inorganic elements (Cd, Hg and Pb) in surface soil and vegetation have been studied for ... -
Study of mercury and selected trace elements in soil in the Norwegian Arctic, Svalbard
(Master thesis, 2016)In this study elemental composition and soil organic matter (SOM) content of surface and mineral soils in Svalbard are presented. The aim is to provide new data on soils in the Arctic and to gain more knowledge about the ... -
Study of organic and inorganic pollutants in former industry areas in Ny-Ålesund, Svalbard, and potential effects on drinking water reservoir Tvillingvatnet
(Master thesis, 2023)Denne masteroppgaven er en studie av utvalgte grunnstoffer og per- og polyfluoralkylstoffer (PFAS) i sediment-, jord- og vannprøver tatt i Ny-Ålesund på Svalbard i august 2022. Oppgaven er en videreføring av fordypningsprosjektet ... -
Study of snow, supraglacial debris and particulate matter released from the glacier systems of Austre Brøggerbreen and Vestre Brøggerbreen at Ny-Ålesund, Svalbard
(Master thesis, 2023)Som et resultat av klimaendringer har Arktis opplev økte temperaturer. En av de mest drastiske trendene har blitt observert på Austre Brøggerbreen i Ny-Ålesundsområdet. Ulike partikulære materiale som kryokonitt, supraglasiale ... -
Study of trace elements, natural organic matter and selected environmental toxicants in soil at Mitrahalvøya, to establish bias correction for studies of long-range atmospheric transported pollutants in Ny-Ålesund
(Master thesis, 2021)The Arctic archipelago Svalbard is an important receptor for long-range atmospheric transported contaminants. However, local emission sources exist as well, but have been only documented in few studies. Accelerated solvent ... -
Study of Water Quality of Recirculated Water in Aquaponic Systems: Study of speciation of selected metals and characterization of the properties of natural organic matter
(Master thesis, 2013)This thesis describes an extensive study on how water quality changes over time in a small scale recirculating system where waste water from smolt production was used to grow lettuce for commercial use. The treatment effect ... -
Study programme driven engineering education: interplay between mathematics and engineering subjects
(Peer reviewed; Journal article, 2022)This paper presents a report from an early phase of the project Mathematics as a Thinking Tool. The primary goal of this project is to increase engineering students’ perception of the relevance of mathematics by developing ... -
Studying the optical gaps of retinal Schiff base in visual pigments using ab initio electronic-structure theory
(Master thesis, 2020)Netthinnen, som er et tynt lag med celler på baksiden av øyeeplet, inneholder to viktige typer proteiner, tapp- og stav-synspigmentene. Stav-synspigmenter eller rhodopsin er ansvarlig for synet i lav lysintensitet, og ... -
