Thermoelectric Properties of Non-Aqueous Electrochemical Cells - Local Reversible Heat Effects Relevant for Lithium Ion Batteries
(Master thesis, 2018)The aim of this thesis was to investigate the thermoelectric properties and local reversible heat effects of cells relevant to lithium-ion batteries. The theory of non-equilibrium thermodynamics and experimental measurements ... -
Thermoelectrochemical Cell with Molten Carbonate Electrolyte
(Journal article, 2017)Industrial processes for production of metals and alloys by metallurgical and electrochemical methods generate a lot of heat due to irreversible losses. The waste heat should be used to generate electricity. Commercial ... -
Thickness Mediated Morphology Evolution in Sub-10-nm Metal Film Deposition: Implications for Non-destructive Testing
(Peer reviewed; Journal article, 2023)Thickness in sub-10-nm metal film deposition is a seldomly explored parameter that can influence not only the film mechanical properties but also the surface functional characteristics. In this study, we designed bilayer ... -
Thin film breakage in oil–in–water emulsions, a multidisciplinary study
(Peer reviewed; Journal article, 2022)Coalescence is a critical phenomenon in separation and transport processes. An improved understanding of coalescence can enhance current models predicting emulsion stability and separation. We here report a combined ... -
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 ... -
Total Synthesis and Semi Synthesis of Steroids: What is the best approach?
(Bachelor thesis, 2022)Steroider, komplekse molekyler med flere kirale sentre og en størrelsesorden av biokjemiske effekter, har vært i søkelyset for mange kjemikere siden 1940-tallet. På grunn av den økende etterspørselen av steroider for ... -
Total synthesis of Dothideopyrone E and Dothideopyone F
(Master thesis, 2021)Dette arbeidet er relatert til syntesen av to naturprodukter, dothideopyrone E og F. Ulike veier har blitt prøvd for å syntetisere disse molekylene. I de første testene ble en Carreira-alkynylering utført for å oppnå gode ... -
Total Synthesis of Dothideopyrones A-D
(Master thesis, 2021)Dothideopyrone A-D [1-4] har blitt isolert fra dothideomycete LRUB20, en endofytisk sopp som lever i planten Leeea rubra.1 Deres cytotoksiske aktiviteter har blitt testet og ser ut til å være lave, men på grunn av den lave ... -
Towards improved characterization of the fate and impact of hydraulic fracturing chemicals to better secure regional water quality
(Peer reviewed; Journal article, 2022)Hydraulic fracturing (HF) of shale and other permeable rock formations to extract gas and oil is a water-intensive process that returns a significant amount of flowback and produced water (FPW). Due to the complex chemical ... -
Trace element status in patients with type 2 diabetes in Norway: The HUNT3 Survey
(Journal article; Peer reviewed, 2017)Several epidemiological studies have indicated that a number of trace elements may play a role in type 2 diabetes (T2D). We investigated the association between prevalent T2D and the concentrations of 25 trace elements in ... -
Trace elements and polychlorinated biphenyls (PCBs) in terrestrial compartments of Svalbard, Norwegian Arctic
(Journal article; Peer reviewed, 2019)Despite being a remote location, the Arctic is a major receptor for anthropogenic pollution transported from the mid-latitudes. Vegetation and underlying organic soils in the Norwegian Arctic, Svalbard were used to study ... -
Trace Elements And Their Interactions With Natural Organic Matter In Water

Trace elements in Arctic river water during seasonal transitions
(Master thesis, 2018)Dissolved concentrations of trace elements in water samples from the Bayelva river in Spitsbergen have been determined. Samples have been collected in the very beginning and very end of the runoff season, otherwise denoted ... -
Trace Elements in Early Phase Type 2 Diabetes Mellitus – a Population-based Study. The HUNT Study in Norway
(Journal article; Peer reviewed, 2017)Differences in trace elements levels between individuals with type 2 diabetes and controls have been reported in several studies in various body fluids and tissues, but results have been inconsistent. In order to examine ... -
Trace Elements in Norwegian and Polish Tea Infusions: Determined by High-Resolution Inductively Coupled Plasma Mass Spectrometry (HR ICP-MS) and Ion Selective Electrode (ISE)
(Master thesis, 2013)AbstractTea from the plant Camellia sinensis is the world’s most popular non-alcoholic beverage, next to water. Tea can be divided into six types, and the most popular teas are black tea, green tea and oolong. In this study ... -
Trace Elements in the General Population and Their Possible Role in Type 2 Diabetes - the Third Nord-Trøndelag Health Survey (HUNT3)
(Doctoral theses at NTNU;2017:308, Doctoral thesis, 2017)Access to reliable information on the elemental contents of the human body is crucial to understand the roles these elements may have in the maintenance of human health. Establishing trace element blood levels in a general ... -
