Automatic monitoring systems for trace metals in natural and waste water: Nafion coated solid metal electrodes for sensitivity enhancement and stability improvement
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:162, Doctoral thesis, 2010)Voltammetry is one of a few analytical methods, suitable for on-line monitoring of trace metals and is sufficiently sensitive in the low μg/L range for this purpose. The advantages of in-situ use of voltammetry are low ... -
Auxiliary donors for phenothiazine sensitizers for dye-sensitized solar cells – how important are they really?
(Journal article; Peer reviewed, 2019)Auxiliary donors are common design motifs for phenothiazine sensitizers for dye-sensitized solar cells. Despite this, there are only a few reports on their overall contribution to the photon-to-electron conversion efficiency. ... -
Avanserte oksidasjonsprosesser for nedbryting av 17α-etinyløstradiol i avløpsvann
(Bachelor thesis, 2022)Avløpsrenseanlegg har begrenset effektivitet i fjerning eller nedbryting av stoffer med østrogen aktivitet, og disse havner da i miljøet. Dette utgjør en risiko for uønskede effekter, særlig for akvatisk liv, da østrogene ... -
Avoiding the Next Silent Spring: Our Chemical Past, Present, and Future
(Peer reviewed; Journal article, 2023)Rachel Carson’s Silent Spring, (1) published just more than 60 years ago, outlined how the indiscriminate use of dichlorodiphenyltrichloroethane (DDT), a potent, environmentally persistent insecticide, was damaging the ... -
Balancing potency, metabolic stability and permeability in pyrrolopyrimidine-based EGFR inhibitors
(Journal article; Peer reviewed, 2016)The present study describes our continuous effort to develop epidermal growth factor receptor (EGFR) inhibitors based on the 6-aryl-pyrrolo[2,3-d]pyrimidin-4-amine scaffold. The activity-ADME space has been evaluated by ... -
Barns kjemiske lekemiljø: Nivå og kilder til PAH i barnehagejord i Trondheim
(Master thesis, 2008)Innholdet av 16 PAH-forbindelser og sumPAH(16) ble bestemt i 107 prøver av overflatejord fordelt på 10 barnehager i Trondheim. Sammenlignet med tidligere undersøkelser av PAH i Trondheim viser barnehagene det laveste ... -
Benzotriazoles and benzothiazoles in paired maternal urine and amniotic fluid samples from Tianjin, China
(Journal article; Peer reviewed, 2018)Benzotriazoles (BTRs) and benzothiazoles (BTHs) are two groups of heterocyclic compounds that are widely detected in the environment. In this study, the levels of BTRs and BTHs in 79 paired maternal urine and amniotic fluid ... -
Benzotriazoles, Benzothiazoles and Inorganic Elements as Markers of Road Pollution Sources in a Sub-Arctic Urban Setting (Trondheim, Norway)
(Master thesis, 2018)Road traffic emissions are known to contribute in environmental pollution and have adverse effects on humans. The emissions of organic and inorganic pollutants from traffic and road activity are established as the primary ... -
Benzotriazoles, Benzothiazoles and Trace Elements in an Urban Road Setting in Trondheim, Norway: Re-Visiting the Chemical Markers of Traffic Pollution
(Journal article; Peer reviewed, 2019)Road traffic emissions are known to contribute heavily to the pollution in urban environments. The aim of this study was to establish specific traffic pollution markers in an urban road setting based on the occurrence ... -
