(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, 2022)he surface protonic conductivity of porous monoclinic ZrO2 sintered at temperatures in the range 700–1100 °C yielding relative densities of around 60% and grain sizes of approximately 160 nm has been studied using impedance ...
-
(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, 2023)Metal–organic frameworks (MOFs) are nanoporous materials composed of organic linkers and inorganic nodes. The large variety of linkers and nodes and the multiple ways to combine them make MOFs highly tunable materials, ...
-
(Doctoral thesis / Doktoravhandling, 2023)The present work provides a fundamental and methodological framework for parameterisation of the thermodynamics and kinetics involved in surface protonic conduction of porous ionic oxides. A novel nomenclature for defect ...

Quantitative chemometric phenotyping of three-dimensional liver organoids by Raman spectral imaging (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Confocal Raman spectral imaging (RSI) enables high-content, label-free visualization of a wide range of molecules in biological specimens without sample preparation. However, reliable quantification of the deconvoluted ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The reactive oxygen species (ROS) scavenging capacities of ginkgolides and bilobalide, which are the peculiar constituents of the extract of Ginkgo biloba, are investigated in silico (level of theory: (SMD)-M06-2X/6-311+ ...

(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 = ...
