Path sampling study of proton transfer reactions using coupled cluster based molecular dynamics
(Master thesis, 2016)Path sampling techniques have been shown to be very efficient tools to study rare events in chemical reaction simulations. Sampling techniques are useful when looking at fairly simple reactions as the breaking of a bond ... -
Path sampling with memory reduction and replica exchange to reach long permeation timescales
(Journal article, 2023)Assessing kinetics in biological processes with molecular dynamics simulations remains a computational and conceptual challenge, given the large time and length scales involved. For kinetic transport of biochemical compounds ... -
PBI som alternativ til Nafion for bruk i PEM brenselceller
(Bachelor thesis, 2024)I dag er det vanlig å bruke Nafion som membranmateriale i proton-utvekslingsmembran (PEM) brenselceller. Det er ønskelig å finne membraner som kan brukes ved temperaturer over 100 °C fordi dette gir bedre kinetikk, øker ... -
PCB i betong
(Master thesis, 2011)Et større riveprosjekt ble igangsatt ved St. Olavs hospital høsten 2010. Riveprosjektet ble også kalt for Norges største riveprosjekt, og tidlige estimater anslo at opp til 50 000 tonn betongbygg skulle rives. I forbindelse ... -
Peltier effects in lithium-ion battery modeling
(Peer reviewed; Journal article, 2021)A high battery temperature has been shown to be critical for lithium-ion batteries in terms of performance, degradation, and safety. Therefore, a precise knowledge of heat sources and sinks in the battery is essential. We ... -
Per- and poly-fluoroalkyl substances in Tawny Owl (Strix aluco) feathers from Trøndelag, Norway
(Journal article; Peer reviewed, 2023)Per- and polyfluoroalkyl substances (PFASs) are contaminants of global concern due to their ubiquitous occurrence in the environment, bioaccumulation and the adverse effects on organisms. Tawny Owls (Strix aluco) are ... -
Per- and polyfluoroalkyl substance (PFAS) removal from soil washing water by coagulation and flocculation
(Peer reviewed; Journal article, 2024)Soil washing is currently attracting attention as a promising remediation strategy for land contaminated with per- and polyfluoroalkyl substances (PFAS). In the soil washing process, the contaminant is transferred from the ... -
Per- and polyfluoroalkyl substances in clothing textiles, and their implications for the environment, health and fabric recycling
(Bachelor thesis, 2024)Denne oppgaven tar for seg bruk og effekter av per- og polyfluoralkylstoffer (PFAS) i klestekstiler, og et litteratursøk om utvalgte PFAS i klær og funksjonelle tekstiler ble utført. Resultatene viste at historiske og ... -
Per- and Polyfluoroalkyl Substances in Liver and Muscle Tissue of Frogs from Greek Wetlands
(Master thesis, 2023)Per- og polyfluorerte stoffer (PFAS) er eksempler på menneskeskapte, persistente organiske miljøgifter (POP). PFAS er alifatiske forbindelser hvor hydrogenene har blitt helt eller delvis byttet ut med fluor. Den sterke ... -
Per- and polyfluoroalkyl substances in shorebirds of Australia
(Master thesis, 2020)Australske kystomåder og våtmarker innehar viktige habitater for dyreliv. I disse områdene forbereder trekkfugler seg på sin kommende reise til hekkeområder i nord ved å søke etter mat for å samle opp energi. Kystfugler ... -
Per- and polyfluoroalkyl substances in Tawny owl feathers from Trøndelag, Norway

Per- og poly- flurorinerte forbindelser i isbjørn (Ursus maritimus) og ringsel (Pusa hispida) i arktis
(Bachelor thesis, 2023)Denne bacheloroppgaven tar for seg hvordan to arktiske predatorer, isbjørn (Ursus maritimus) og ringsel (Pusa Hispida) påvirkes av miljøgiften perfluorooktylsulfonat (PFOS). Målte konsentrasjoner av PFOS fra andre studier ... -
Perfluoroalkyl and Polyfluoroalkyl Substances in Consumer Products, Fast Food Packaging, Waste Electrical and Electronic Equipment, and End-of-Life Vehicle Residual Fluff in a Circular Economy
(Master thesis, 2020)Per- and polyfluoroalkyl substances (PFASs)—a class of extremely persistent man-made chemicals with unique hydrophobic and lipophobic properties and thus applied in consumer products. Several PFASs have been associated ... -
Performance analysis of heat and energy recovery ventilators using exergy analysis and nonequilibrium thermodynamics
(Journal article; Peer reviewed, 2018)The increased attention to energy savings has contributed to more widespread use of energy recovery systems for building ventilation. We investigate the efficiency of such systems under different outdoor conditions using ... -
