(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Cholera toxin (CT) and Escherichia coli heat-labile enterotoxin (LT) are structurally similar AB 5 -type protein toxins. They move from the cell surface to the endoplasmic reticulum where the A1 catalytic subunit ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Mixtures of amphiphilic polymers and surfactants are used in a wide range of applications, e.g., pharmaceuticals, detergents, cosmetics, and drug delivery systems. Still, many questions remain on how the structure and, in ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The Schlenk equilibrium is a complex reaction governing the presence of multiple chemical species in solution of Grignard reagents. The full characterization at the molecular level of the transformation of CH3MgCl into ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The oxidation of ammonia is a key reaction for the production of artificial fertilizers and for environmental protection. Depending on the area of application, the catalytic reaction needs to be tuned toward the production ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)TiO2 was known as a golden heterogeneous photocatalyst due to its chemical stability, low cost, nontoxicity, and strong oxidizing power. However, anatase TiO2 predominantly absorbs the photon energy in the ultraviolet ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We propose the first model of a polypeptide chain based on a hybrid-particle field approach. The intramolecular potential is built on a two-bead coarse grain mapping for each amino acid. We employ a combined potential for ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We develop and test specific coarse-grained models for charged amphiphilic systems such as palmitoyloleoylphosphatidylglycerol (POPG) lipid bilayer and sodium dodecyl sulfate (SDS) surfactant in an aqueous environment, to ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Hybrid particle-field methods are computationally efficient approaches for modeling soft matter systems. So far, applications of these methodologies have been limited to constant volume conditions. Here, we reformulate ...
-
(Doctoral thesis / Doktoravhandling, 2017)Mye av dagens høyteknologiske utstyr og apparater ville sannsynligvis ikke sett dagens lys hvis ikke det hadde vært for materialteknologiens stadige fremskritt. I jakten på stadige forbedringer av slik teknologi må man ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ...

(Master thesis / Hovedoppgave, 2004)Dette arbeidet har i hovedsak tatt for seg studiet av en høytemperatur brenselcelle med protonledende elektrolytt for hydrogen og ammoniakk i temperaturintervallet 600 - 900ºC. BaCe0,9Y0,1O2,95 (BCY) ble benyttet som ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Metal–organic frameworks (MOFs) show great prospect as catalysts and catalyst support materials. Yet, studies that address their dynamic, kinetic, and mechanistic role in target reactions are scarce. In this study, an ...
-
(Master thesis / Hovedoppgave, 2004)In-situ pulvernøytron- og synkrotron røntgendiffraksjon har blitt brukt til å undersøke desorpsjonsegenskapene og strukturelle forhold for utvalgte intermetalliske hydrider. Ved hjelp av diffraksjonsdata fra in-situ ...

Hydrophilic interaction chromatographic separation of 8 deoxynucleotide triphosphates (dNTPs) and nucleotide triphosphates (NTPs).Restricted Access (Master thesis / Masteroppgave, 2010)Eight deoxynucleoside triphosphates (dNTPs) and nucleoside triphosphates (NTPs): ATP, CTP, GTP, UTP, dATP, dCTP, dGTP and dTTP, were separated using two 15 cm, 2.1. mm I.D. ZIC-pHILIC columns coupled in series, using simple ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The crystal structure of L-valyl-L-leucine acetonitrile solvate presented here adds to 24 previously reported structures of dipeptides constructed from the five nonpolar amino acids L-alanine, L-valine, L-isoleucine, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)With the increasing demand for green energy, there is a great urgency to develop perm-selective, economical and robust membranes for applications in fuel cells. Metal–organic frameworks are attractive materials for this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We present HylleraasMD (HyMD), a comprehensive implementation of the recently proposed Hamiltonian formulation of hybrid particle-field molecular dynamics. The methodology is based on a tunable, grid-independent length-scale ...
