NOx Storage reduction on copper and barium containing micro- and mesoporous materials
(Master thesis, 2013)NOx storage reduction (NSR) has been pointed out as a possible solution to meet the stringent emission ceilings for NOx. The NOx storage reduction catalyst is designed to work under cyclic conditions, alternating between ... -
Numerical modelling of distinct ice lenses in frost heave
(Peer reviewed; Journal article, 2021)Frost heave happens when three conditions coincide: the temperature is below the normal freezing point of bulk water, the sub-cooled water is connected to a water reservoir, and the mechanical conditions of the soil allows ... -
o-Quinonoid Heterocycles: Synthesis and Crystal Structure of 2,3-Dicyano-5,7-bismethylthieno[3,4-b]pyrazine
(Journal article; Peer reviewed, 2007)2,3-Dicyano-5,7-bismethylthieno[3,4-b]pyrazine (5), has been obtained as a minor product from reactions of S-nucleophiles with 5,6-di(1-bromoethyl)pyrazine-2,3- dicarbonitrile (3), or from a condensation of 4-hydroxy-2 ... -
Observation of Ultrafast Intersystem Crossing in Thymine by Extreme Ultraviolet Time-Resolved Photoelectron Spectroscopy
(Journal article; Peer reviewed, 2019)We studied the photoinduced ultrafast relaxation dynamics of the nucleobase thymine using gas-phase time-resolved photoelectron spectroscopy. By employing extreme ultraviolet pulses from high harmonic generation for ... -
Occurence of bisphenols and benzophenone UV-filters in plastic waste: A circular economy perspective
(Master thesis, 2021)Plastikk har blitt et utrolig viktig materiale i forbruksvarer slik som matembalasje, men kan skape problemer med avfall. I 2018 ble 17.8 millioner tonn med brukt plastembalasje samplet inn. Resirkulering er en måte å ... -
Occurrence and sorption behaviour of bisphenols and benzophenone UV-filters in e-waste plastic and vehicle fluff
(Journal article; Peer reviewed, 2021)Bisphenols and benzophenone UV-filters are hazardous, high production volume chemicals. There is concern that these contaminants could leach into the environment or be recycled into new products during waste management. ... -
Occurrence of Bisphenols and Benzophenone UV Filters in White-Tailed Eagles (Haliaeetus albicilla) from Smøla, Norway
(Journal article; Peer reviewed, 2021)There is a growing concern about the occurrence of bisphenols and benzophenone UV filters in natural ecosystems, while data are limited regarding their actual occurrence in wildlife species, especially in raptors. In this ... -
Occurrence of brominated and organophosphate flame retardants in Norwegian wastewater
(Master thesis, 2021)Bromerte og fosfororganiske flammehemmere (BFR og OPFR) brukes for å gjøre produkter mindre brannfarlige, og har sett økt bruk i takt med utbredelsen av syntetiske, lettantennelige polymerer de siste tiårene. Høye nivåer ... -
Occurrence of legacy and novel Per- and Polyfluoroalkyl Substances (PFAS) in plastics, e-waste plastics and mobile phone waste
