(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Earthquakes at lower crustal depths are common during continental collision. However, the coseismic weakening mechanisms required to propagate an earthquake at high pressures are poorly understood. Transient ...

Lower Semicontinuity of the Universal Functional in Paramagnetic Current-Density Functional Theory (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A cornerstone of current–density functional theory (CDFT) in its paramagnetic formulation is proven. After a brief outline of the mathematical structure of CDFT, the lower semicontinuity and expectation-valuedness of the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)In the present contribution we assess the luminescent properties of amorphous europium titanium phosphate thin films. The films have been deposited by atomic layer deposition, using the precursor combinations Eu(thd)3 (thd ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)UV to visible and near-infrared converting thin films of YbVO4 have been deposited by atomic layer deposition, using the precursor combinations Yb(thd)3 (thd = 2,2,6,6-tetramethyl-3,5-heptanedione) and O3, and VO(thd)2 and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Homogeneous catalysis using transition metal complexes is ubiquitously used for organic synthesis, as well as technologically relevant in applications such as water splitting and CO2 reduction. The key steps underlying ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)We present a numerical approach to magnetic optical rotation based on real-time time-dependent electronic-structure theory. Not relying on perturbation expansions in the magnetic-field strength, the formulation allows us ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)We study the effects of magnetic fields in the context of magnetic field density-functional theory (BDFT), where the energy is a functional of the electron density ρ and the magnetic field B. We show that this approach is ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)The Berry connection and curvature are key components of electronic structure calculations for atoms and molecules in magnetic fields. They ensure the correct translational behavior of the effective nuclear Hamiltonian and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The topology of twisted molecular rings is characterized by the linking number, which is equal to the sum of the twist—a local property of the molecular frame—and the writhe—a global parameter, which represents the bending ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)National long-term monitoring programs on persistent organic pollutants (POPs) in background air have traditionally relied on active air sampling techniques. Due to limited spatial coverage of active air samplers, questions ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Chlorosomes are supramolecular aggregates that contain thousands of bacteriochlorophyll molecules. They perform the most efficient ultrafast excitation energy transfer of all natural light-harvesting complexes. Their broad ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The transition from integrated petrochemical complexes toward decentralized chemical plants utilizing distributed feedstocks calls for simpler downstream unit operations. Less separation steps are attractive for future ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We have used operando X-ray diffraction computed tomography (XRD-CT) analysed by rigorous crystallographic methods to reveal the behaviour of a zeolite/alumina based catalyst extrudate in the methanol-to-hydrocarbon reaction ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Oxysterols are potential biomarkers for liver metabolism that are altered under disease conditions such as non-alcoholic fatty liver disease (NAFLD). We here apply sterolomics to organoids used for disease modeling of ...
