(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1993)© 1993 Acta Chemica Scandinavica
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)We study the effects of magnetic fields in the context of magnetic field density-functional theory (BDFT), where the energy is a functional of the electron density ρ and the magnetic field B. We show that this approach is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The topology of twisted molecular rings is characterized by the linking number, which is equal to the sum of the twist—a local property of the molecular frame—and the writhe—a global parameter, which represents the bending ...

(Master thesis / Masteroppgave, 2015)Masteroppgaven er en undersøkelse som ble gjort i forbindelse med 65.000 kjemisett som ble laget for å markere 150 års jubileet for massevirkningsloven. Massevirkningsloven ble framsatt av to unge, lovende forskere Cato ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)The electrical properties and the charge carrier mechanism of porous 8 mol% yttria-stabilized zirconia (8YSZ) ceramic samples have been investigated over wide ranges of relative humidity (RH) and temperature (25-400 ºC). ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)We used multiple sets of simulations both at the atomistic and coarse-grained level of resolution to investigate interaction and binding of α-tochoperol transfer protein (α-TTP) to phosphatidylinositol phosphate lipids ...
-
(Doctoral thesis / Doktoravhandling, 2017)This PhD thesis deeply analyzes the mechanistic and kinetic behavior of methanol and dimethyl ether (DME) in the industrially relevant Methanol-To-Hydrocarbons (MTH) reaction, which employs zeolitic materials as catalysts. ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)A computational study on the molecular mechanism of formic acid dehydrogenation in the presence of Cu-amine complex has been carried out in order to shed light on the role of the amine in determining the catalyst activity. ...

(Master thesis / Hovedoppgave, 2004)SAMMENDRAG Ukalsinert og kalsinert hydrotalsitt har blitt impregnert fra en løsning av heksakloroplatina (H2PtCl6). H2PtCl6 var løst opp i enten ionebyttet vann eller etanol. pH i impregneringsløsningen og atmosfæren har ...
-
(Master thesis / Masteroppgave, 2013)Denne oppgaven omhandler mekanistiske studier av reaksjoner mellom permanganationet og eten. Reaksjonene er studert ved bruk av massespektrometri og kvantekjemiske metoder. Eksperimenter ved bruk av massespektrometri ...

(Doctoral thesis / Doktoravhandling, 2015)Det er den organiske formen av kvikksølv, metylkvikksølv, som står i sentrum for kvikksølvforskningen. Metylkvikksølv anrikes opp gjennom næringskjedene, så selv om vannet ikke inneholder mye kvikksølv kan fisk allikevel ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Metal alkylidenes, which are key organometallic intermediates in reactions such as olefination or alkene and alkane metathesis, are typically generated from metal dialkyl compounds [M](CH2R)2 that show distinctively ...

(Doctoral thesis / Doktoravhandling, 2019)
-
(Doctoral thesis / Doktoravhandling, 2012)Fuel cells are expected to serve as a contribution to meet the demand for clean energy. High temperature fuel cells such as solid oxide fuel cells (SOFC) and proton ceramic fuel cells (PCFC) are developed for use as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Metallacyclobutanes are an important class of organometallic intermediates, due to their role in olefin metathesis. They can have either planar or puckered rings associated with characteristic chemical and physical properties. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Cu-exchanged zeolites possess active sites that are able to cleave the C–H bond of methane at temperatures ≤200 °C, enabling its selective partial oxidation to methanol. Herein we explore this process over Cu-SSZ-13 ...
-
(Master thesis / Masteroppgave, 2010)The methanol-to-hydrocarbons (MTH) reaction is a flexible alternative step in the upgrading of natural gas, coal or biomass. By tuning the catalyst and process conditions, methanol can be converted into a variety of ...
