Comparison of Long-Range Atmospheric Transported Pollutants in Snow and Moss Samples from Svalbard
(Master thesis, 2022)Som en del av Arktis er Svalbard et fjerntliggende område med få lokale kilder som slipper ut forurensninger til miljøet. Til tross for dette er det observert høyere konsentrasjoner av forurensninger enn hva som er forventet ... -
Studies of environmental footprint in Brøggerdalen after rocket launching in Ny-Ålesund
(Master thesis, 2022)I denne masteroppgåva blei nivå av eit utval sporelement og polyklorerte bifenyl (PCB) målt i sedimentprøver frå Brøggerdalen, Ny- Ålesund, Sval- bard. Prøvetaking vart gjennomført i august 2021. Målet med denne oppgåva var ... -
Au(III) complexes with tetradentate-cyclam-based ligands
(Peer reviewed; Journal article, 2021)Chiral cyclam (1,4,8,11-tetraazacyclotetradecane) derivatives were synthesized stepwise from chiral mono-Boc-1,2-diamines and (dialkyl)malonyl dichloride via open diamide-bis(N-Boc-amino) intermediates (65–91%). Deprotection ... -
Preparation of benzannulated spiroketals by gold(III) catalyzed spirocyclization of alkynyl diols
(Peer reviewed; Journal article, 2021)The first gold(III)-oxazoline catalysed intramolecular tandem dihydroalkoxylations of alkynyl diols to give benzannulated 5,6-spiroketal products is reported. The results showed that Au(III)-bisoxazoline (BOX) and ... -

Deciphering the composition and transformation of dissolved organic matter in recirculating aquaculture systems by high-resolution mass spectrometry
(Doctoral theses at NTNU;2022:237, Doctoral thesis, 2022)The continuous increase in the human population is prompting the need for aquaculture systems able to sustain the global demand for fish without affecting the environment. Recirculating aquaculture systems (RAS) are a new ... -
Scaling factors for channel width variations in tree-like flow field patterns for polymer electrolyte membrane fuel cells - An experimental study
(Peer reviewed; Journal article, 2021)To have a uniform distribution of reactants is an advantage to a fuel cell. We report results for such a distributor with tree-like flow field plates (FFP). Numerical simulations have shown that the width scaling parameters ... -
Local thermodynamic description of isothermal single-phase flow in porous media
(Journal article; Peer reviewed, 2022)Darcy's law for porous media transport is given a new local thermodynamic basis in terms of the grand potential of confined fluids. The local effective pressure gradient is determined using non-equilibrium molecular dynamics, ... -
An implicit solvent coarse-grained model for alginate hydrogels crosslinked with chitosan oligomers
(Master thesis, 2022)En grovkornet tilnærming er tatt i bruk i dette masterprosjektet for å undersøke hydrogeler i mikroskopisk skala ved bruk av molekylær dynamikksimuleringer. Hydrogelene som er studert er sammensatt av alginater tverrbundet ... -
The distribution of persistent, mobile and toxic (PMT) pharmaceuticals and personal care products monitored across Chinese water resources
(Peer reviewed; Journal article, 2021)Hazard classifications have recently been introduced for persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances, which are those that negatively impact water resources if substantially ... -
Exposures to phthalates and bisphenols in pregnancy and postpartum weight gain in a population-based longitudinal birth cohort
(Peer reviewed; Journal article, 2020)Background Experimental evidence suggests that exposures to phthalates and bisphenols may interfere with processes related to glucose and lipid metabolism, insulin sensitivity, and body weight. Few studies have considered ... -
Fetal phthalates and bisphenols and childhood lipid and glucose metabolism. A population-based prospective cohort study
(Peer reviewed; Journal article, 2020)Background and aims Fetal exposure to endocrine disruptors such as phthalates and bisphenols may lead to developmental metabolic adaptations. We examined associations of maternal phthalate and bisphenol urine concentrations ... -
Saturation of radiative heat transfer due to many-body thermalization
(Peer reviewed; Journal article, 2020)Radiative heat transfer between two bodies saturates at very short separation distances due to the nonlocal optical response of the materials. In this work, we show that the presence of radiative interactions with a third ... -
Screening and characterisation of CdTe/CdS quantum dot-binding peptides for material surface functionalisation
(Peer reviewed; Journal article, 2020)Quantum dots (QDs) are promising nanomaterials due to their unique photophysical properties. For them to be useful in biological applications, the particle surface generally needs to be conjugated to biological molecules, ... -
Simulating absorption spectra of flavonoids in aqueous solution: A polarizable QM/MM study
