Plasmonic Resonances of Metal Nanoparticles: Atomistic vs. Continuum Approaches
(Peer reviewed; Journal article, 2020)The fully atomistic model, ωFQ, based on textbook concepts (Drude theory, electrostatics, quantum tunneling) and recently developed by some of the present authors in Nanoscale, 11, 6004-6015 is applied to the calculation ... -
Coupled cluster investigations of spectroscopic properties in molecular and crystalline systems
(Doctoral theses at NTNU;2022:343, Doctoral thesis, 2022)Theoretical studies of spectroscopic properties are of great value, both by themselves and in combination with experiments. The highly accurate coupled cluster methods are attractive options for such studies. Due to their ... -
Lithium Extraction from Seawater Brine; Investigating a Frugal Method that could be easily Implemented in Developing Countries
(Master thesis, 2022)Behovet for litium (Li) øker i takt med det økende behovet for energilagring og blir nærmer seg p bli en forsyningsrisiko. I tillegg er effekten av utløpet av saltlaken fra ferskvannsindustrien et økende problem som kan ... -
Halogenated Pyrrolopyrimidines with Low MIC on Staphylococcus aureus and Synergistic Effects with an Antimicrobial Peptide
(Peer reviewed; Journal article, 2022)Currently, there is a world-wide rise in antibiotic resistance causing burdens to individuals and public healthcare systems. At the same time drug development is lagging behind. Therefore, finding new ways of treating ... -
Lipase Catalyzed Synthesis of Enantiopure Precursors and Derivatives for β-Blockers Practolol, Pindolol and Carteolol
(Peer reviewed; Journal article, 2021)Sustainable methods for producing enantiopure drugs have been developed. Chlorohydrins as building blocks for several β-blockers have been synthesized in high enantiomeric purity by chemo-enzymatic methods. The yield of ... -
Untargeted analysis of DOM in an arctic fjord
(Master thesis, 2022)Arktis er et complexed økosystem system under raskt endring. takket være global oppvarming er forståelsen for de kjemiske egenskapene til denne regionen uunnværlige. Denne studien tar for sesongendringene av vannløst ... -
Studie av vannkvalitet med hensyn på kjemiske parametere i RAS-systemer i akvakultur
(Master thesis, 2022)Lengre oppholdstid for laks i åpne merder øker risiko for sykdom, rømning av fisk, utslipp av organiske avfallstoffer og lakselus. For å redusere utfordringer knyttet til dette kan laksen holdes lenger i landbaserte ... -
Total Mercury Distribution in the Barents Sea and the Arctic Ocean Surface Sediments
(Master thesis, 2022)Mercury (Hg) has been a trace metal of interest for decades due to its neurotoxic effects on humans and other organisms coupled with its ability to bioaccumulate and biomagnify. Areas like the Arctic and the ocean floor ... -
Levels of Per- and polyfluoroalkyl substances (PFAS), trace elements, and steroid hormones in Arctic char (Salvelinus alpinus) from Lake Diesetvatnet, Svalbard
(Master thesis, 2022)Arktis betegnes ofte som et uberørt område, men tilstedeværelsen av forurensninger som Per- og polyfluoralkylstoffer (PFAS) og kvikksølv har blitt påvist i miljøet og dyrelivet på grunn av at disse forbindelse har potensialet ... -
Mercury in Marine Arctic Sediments
(Master thesis, 2022)Økende temperaturer grunnet klimaendringer forventes å frigjøre kvikksølv lagret i permafrost, og øke mengden kvikksølv som blir transportert til Arktiske hav fra elver i Sibir (Liem-Nguyen et al., 2022; Schuster et al., ... -
Multiomics analysis of rheumatoid arthritis yields sequence variants that have large effects on risk of the seropositive subset
(Peer reviewed; Journal article, 2022)Objectives To find causal genes for rheumatoid arthritis (RA) and its seropositive (RF and/or ACPA positive) and seronegative subsets. Methods We performed a genome-wide association study (GWAS) of 31 313 RA cases (68% ... -
Production and Analytical Characterization of Environmentally Relevant Micro-and Nanoplastic Reference Materials (<100 μm)
(Master thesis, 2022)Plastforurensning er et økende problem verden rundt. Forsøpling med plast direkte i miljøet gjør at plastrester og mindre fragmenter flyter rundt i byer og i naturen, helt til de blir degradert til mikro- og nanoplast. ... -
Kinetic and Isotherm Modelling for the Investigation of Adsorption of Pharmaceuticals onto Suspended Particles in Marine Environmental Conditions
(Master thesis, 2022)Legemidler er nylig oppdagede forurensende forbindelser som slippes ut i det marine miljøet uten særlig omtanke. Man tror at adsorpsjon til suspenderte partikler kan bidra til akkumulering av legemidler i havet, noe som ... -
Statistical Analysis of Paint Ingredients' Effect on Hydrophobicity and Surface Roughness - Using the Power Spectral Density Function to Quantify Roughness
(Master thesis, 2022)Siden globale temperaturer øker grunnet drivhusgassutslipp og drivstoffpriser fortsetter å heves, er skipsindustrien på jakt etter en måte å minske drivstofforbruket. En forslått løsning er luftsmøringssystemer som pumper ... -
