(Master thesis / Hovedoppgave, 2006)ABSTRACT The main aim for the work on this thesis was to find a fast and sensitive method for qualitative and quantitative determination of the naphthenic acids (NAs) called the ARN acid family in crude oil. As there are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The uptake of specific fatty acids in humans is dependent on their position on the glycerol backbone. There is a great interest in methods that can access this information fast and accurately. By way of high‐resolution ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract A new and robust statistical approach is explored with the objective to derive quantitative and reliable information on the molecular dynamics within distinct domains (crystalline, intermediate and amorphous ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2022)This thesis illuminates the opportunities for Quinizarin (Qz) as an organic sensitizer in LnF3 (Ln=Y, Nd, Tm, Yb) thin films for upconversion. Lanthanides show great promise as active materials for upconversion technologies, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Atomic layer deposition (ALD) is a remarkable synthesis tool due to the vast array of materials that can be deposited and the complexity of structures that can be designed. The low-temperature layer-by-layer approach even ...

(Master thesis / Masteroppgave, 2011)I et prosjekt ved Institutt for Energiteknikk (IFE) skulle mekanismer studeres ved bruk av surfaktanter i kombinasjon med superkritisk CO2 for økt utvinning av restolje fra eldre oljereservoarer. Surfaktant sammen med CO2 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1994)The results of polarized micro-Raman scattering experiments on YBa 2 Fe 3 O 8 + δ with δ=0.1 are reported. We identified seven out of the total ten by symmetry Raman-allowed phonons at 134 cm − 1 ( A 1 g ), 148 cm − 1 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Recently, we have implemented a scheme for the calculation of the adiabatic connection linking the Kohn-Sham system to the physical, interacting system. This scheme uses a generalized Lieb functional, in which the ...

(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 ...
-
(Master thesis / Masteroppgave, 2022)The work in this thesis is divided into four parts: 1. The study and development of a novel synthesis of 2,5-dioxopyrrolidin-1-yl 2-diazoacetate, a much desired building block (BB) for synthesis of diazo-esters and -amides. ...
-
(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 ...
