(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Aim: For isolation of exosomes, differential ultracentrifugation and an isolation kit from a major vendor were compared. Materials & methods: ‘Case study’ exosomes isolated from patient-derived cells from glioblastoma ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Chlorosomes from green bacteria perform the most efficient light capture and energy transfer, as observed among natural light-harvesting antennae. Hence, their unique functional properties inspire developments in artificial ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Proton-transfer-reaction mass spectrometry (PTR-MS) is widely used for measuring organic trace gases in air. In traditional PTR-MS, both nonpolar and polar analytes are ionized with unit efficiency, as predicted from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Ultralow flow LC employs ultra‐narrow bore columns and mid‐range pL/min to low nL/min flow rates (i.e., ≤20 nL/min). The separation columns that are used under these conditions are typically 2–30 μm in inner diameter. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The direct activation of methane to methanol (MTM) proceeds through a chemical-looping process over Cu-oxo sites in zeolites. Herein, we extend the overall understanding of oxidation reactions over metal-oxo sites and C–H ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The maximum overlap method (MOM) provides a simple but powerful approach for performing calculations on excited states by targeting solutions with non-Aufbau occupations from a reference set of molecular orbitals. In this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Cyclic volatile methyl siloxanes (cVMS) are emitted to aquatic environments with wastewater effluents. Here, we evaluate the environmental behavior of three cVMS compounds (octamethylcyclotetrasiloxane (D4), decamethylcy ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Progress in the field of Na‐based batteries strongly relies on the development of new advanced materials. However, one of the main challenges of implementing new electrode materials is the understanding of their mechanisms ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Small pore zeolites have shown great potential in a number of catalytic reactions. While Mo-containing medium pore zeolites have been widely studied for methane dehydroaromatisation (MDA), the use of small pore supports ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Lewis acids (LAs) have been shown to accelerate hydrogenation of CO2, but the underlying mechanistic details remain to be elucidated. We have employed computational methods to investigate how LAs affect CO2 hydrogenation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Lipid nanodiscs formed by mixtures of styrene maleic acid (SMA) copolymers and lipid membranes are important tools for studying membrane proteins in many biotechnological applications. However, molecular interactions leading ...
-
(Master thesis / Hovedoppgave, 2005)Sammendrag Dette arbeidet har gått ut på å undersøke den magnetiske faseovergangen ved TC i prøver av typen Mn1-xFexAs (0,00 ≤ x ≤ 0,03) og Mn1-xTixAs (0,00 ≤ x ≤ .0,10) ved å måle entropiendring og endring i magnetisk ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The unique‐continuation property from sets of positive measure is here proven for the many‐body magnetic Schrödinger equation. This property guarantees that if a solution of the Schrödinger equation vanishes on a set of ...
-
Unitary coupled-cluster for quantum computation of molecular properties in a strong magnetic field (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)In truncated coupled-cluster (CC) theories, non-variational and/or generally complex ground-state energies can occur. This is due to the non-Hermitian nature of the similarity transformed Hamiltonian matrix in combination ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)More than four decades ago, a complex identified as the planar homoleptic lithium nickelate “Li3NiPh3(solv)3” was reported by Taube and co-workers. This and subsequent reports involving this complex have lain dormant since; ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Development of new anode materials for Na-ion batteries strongly depends on a detailed understanding of their cycling mechanism. Due to instrumental limitations, the majority of mechanistic studies focus on operando ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Differentiating chemical and thermal expansion is virtually impossible to achieve experimentally. While thermal expansion stems from a softening of the phonon spectra, chemical expansion depends on the chemical composition ...
