(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Rock failure accommodating the emplacement of magmatic intrusions is controlled by the local stress regime within the host rock. Most of the mechanical models addressing rock failure conditions (e.g., for a given tectonic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this study, the results of hydrogen plasma treatments of β-Ga2O3, α-Ga2O3, κ-Ga2O3 and γ-Ga2O3 polymorphs are analyzed. For all polymorphs, the results strongly suggest an interplay between donor-like hydrogen configurations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Here, we report the synthesis and magnetic properties of a novel, centrosymmetric, quasi-1D spin chain system La3VWS3O6, with hexagonal crystal structure (P63/m, a = 9.460 76(3), c = 5.518 09(2) Å). Pure powders were ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We use 3D magnetohydrodynamic CO5BOLD model atmospheres to study the interplay between magnetic fields and convection in the atmospheres of red giant stars. We find that vortex-like structures occur prominently in stars ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Sills emplaced in organic-rich sedimentary rocks trigger the generation and migration of hydrocarbons in volcanic sedimentary basins. Based on seismic and geological observations, numerical modeling studies of hydrothermal ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Polycrystalline cuprous oxide (Cu2O) thin films were sputtered, annealed (900 °C rapid thermal annealing) and subsequently implanted with various hydrogen ion (H+) doses from 5E13 to 2E15 cm−2 with a low acceleration energy ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)In the present study, a series of H-ZSM-22 mesoporous catalysts resulting from three different desilication treatments (NaOH treatment, treatment using mixtures of NaOH/CTAB and using mixtures of NaOH/TBAOH) and sequential ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Single crystalline bulk and epitaxially grown gallium oxide (β–Ga2O3) was irradiated by 0.6 and 1.9 MeV protons to doses ranging from 5 × 109 to 6 × 1014 cm−2 in order to study the impact on charge carrier concentration ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this work, impedance spectroscopy has been employed to explore the electrochemical behaviour of a 15 cm2 complete tubular cell with BaZr0.8Ce0.1Y0.1O3-δ (BZCY) electrolyte and two asymmetric Ni-BCZY cermet electrodes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Aerosol–cloud interactions contribute to a large portion of the spread in estimates of climate forcing, climate sensitivity and future projections. An important part of this uncertainty is how much new particle formation ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The increased transport of terrestrially derived organic material (tOM) from catchments to rivers and lakes is leading to browning of northern freshwaters.(1) Although the same environmental drivers can be expected to lead ...
-
Importance of Val567 on heme environment and substrate recognition of neuronal nitric oxide synthase (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Nitric oxide (NO) produced by mammalian nitric oxide synthases (mNOSs) is an important mediator in a variety of physiological functions. Crystal structures of mNOSs have shown strong conservation of the active‐site residue ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)2-Aminobiphenyl palladacycles are among the most successful precatalysts for Pd-catalyzed cross-coupling reactions, including aryl amination. However, the role of NH-carbazole, a byproduct of precatalyst activation, remains ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In a solid-liquid dual-phase CO2 separation membrane, the native ions in the molten alkali carbonate, including carbonate anions and metal cations can transport CO2 in a process that is charge-compensated by electronic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Disorder-induced formation of metastable Ga2O3 polymorphs as well as the recovery of the stable state upon annealing attract attention because of the fundamental novelty and rapidly increasing interest in the use of Ga2O3 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Mimicking natural photosynthesis by direct photoelectrochemical (PEC) reduction of CO2 to chemicals and fuels requires complex cell assemblies with limitations in selectivity, efficiency, cost, and stability. Here, we ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Molybdenum disulphide (MoS2) is a rising star among transition-metal dichalcogenides in photovoltaics, diodes, electronic circuits, transistors and as a photocatalyst for hydrogen evolution. A wide range of MoS2 polymorphs ...
