(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Chorismate mutase is a well‐known model enzyme, catalyzing the Claisen rearrangement of chorismate to prephenate. Recent high‐resolution crystal structures along the reaction coordinate of this enzyme enabled computational ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The catalytic hydrogenation of amides is an atom economical method to synthesize amines. Previously, it was serendipitously discovered that the combination of a secondary amide co-catalyst with (iPrPNP)Fe(H)(CO) (iPrPNP = ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The reactions of OH radicals with CH3NHCHO (N-methylformamide, MF) and (CH3)2NCHO (N,N-dimethylformamide, DMF) have been studied by experimental and computational methods. Rate coefficients were determined as a function ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Black TiO2 has emerged as one of the most promising photocatalysts recently discovered. The reason behind its catalytic activity is considered to be due to the presence of defects and Ti3+ species at the surface of black ...
-
(Master thesis / Masteroppgave, 2018)The availability of many elements is decreasing due to extended use. One possible solution to this problem is the recovery of metals from waste. Fly ash from municipal solid waste (MSW) incineration contains many metals ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Two forms, α and β, are known for the racemic amino acid DL-methionine, C5H11NO2S. The phase transition between them, taking place around 326 K, is associated with sliding at the central interfaces of the hydrophobic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Diffraction data were taken from the contribution named `β-DL-Methionine at 105 K' by Alagar et al. [Acta Cryst. (2005). E61, o1165-o1167]. Refinement of the coordinates of the three amino H atoms, previously constrained ...
-
(Doctoral thesis / Doktoravhandling, 2012)The present work focuses on the redox energetics of novel perovskite-type oxygen carriers for chemical looping reforming. The aim of this study is to increase the level of knowledge on the redox characteristics of materials ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)Molecular dynamics simulations (dissipative particle dynamics–DPD) were developed and used to quantify wall-normal migration of polymer chains in microchannel Poseuille flow. Crossflow migration due to viscous interaction ...

Relation between Ring Currents and Hydrogenation Enthalpies for Assessing the Degree of Aromaticity (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Magnetically induced ring-current strength susceptibilities and nucleus independent chemical shifts (NICS) have been studied for 15 single-ring aromatic, antiaromatic, and nonaromatic molecules. The current densities have ...
