(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Neutral shallow donors (D0) in ZnO have emerged as a promising candidate for solid-state spin qubits. Here we report on the formation of D0 in ZnO via implantation of In and subsequent annealing. The implanted In donors ...

Properties of novel non-silicon materials for photovoltaic applications: A first-principle insight (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Due to the low absorption coefficients of crystalline silicon-based solar cells, researchers have focused on non-silicon semiconductors with direct band gaps for the development of novel photovoltaic devices. In this study, ...

Protracted localization of metamorphism and deformation in a heterogeneous lower-crustal shear zone (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Deformation of the continental crust is influenced by the pre-existing structural framework, fluid availability, strain rate, and pressure-temperature conditions. We investigate the evolution of a large (hundreds-of-meters ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)During continental collision, large tracts of crust are mobilized along major shear zones. The metamorphic conditions at which these zones operate, the duration of thrusting, and the deformation processes that facilitated ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We have studied a series of Pd/Au alloys as Pt-catchment materials, both in lab-scale experiments and in an industrial ammonia oxidation plant. Our focus has been on how bulk Pt diffusion affects grain reconstruction in ...

(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, 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, ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Shallow aseismic creep is a key deformation component along plate boundaries that contributes to the energy budget during the seismic cycle. Several major active continental faults show spatial alternation of creeping and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Copepods are a critical component of ocean ecosystems, providing an important link between phytoplankton and higher trophic levels as well as regulating biogeochemical cycles of carbon (C) and nutrients. Lipid-rich animals ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Rab proteins are master regulators of intracellular membrane trafficking, but they also contribute to cell division, signaling, polarization, and migration. The majority of the works describing the mechanisms used by Rab ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Abstract Realization of radiation-hard electronic devices that are able to work in harsh environments requires deep understanding of the processes of defect formation/evolution occurring in semiconductors bombarded ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Defect accumulation and annealing phenomena in Si-implanted monoclinic gallium oxide (β-Ga 2 O 3 ) wafers, having [Formula: see text], (010), and (001) orientations, were studied by Rutherford backscattering spectrometry ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Thicker snow cover in permafrost areas causes deeper active layers and thaw subsidence, which alter local hydrology and may amplify the loss of soil carbon. However, the potential for changes in snow cover and surface ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The incomplete understanding of glacier dynamics is a major source of uncertainty in assessments of sea-level rise from land-based ice. Through increased ice discharge into the oceans, accelerating glacier flow has the ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Fluid flow in crystalline rocks in the absence of fractures or ductile shear zones dominantly occurs by grain boundary diffusion, as it is faster than volume diffusion. It is, however, unclear how reactive fluid ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)An experimental investigation was conducted to explore spectroscopic and structural characterization of semiconducting yttrium oxide thin film deposited at 623 K (±5K) utilizing reactive pulsed direct current magnetron ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Depleted oil reservoirs are considered a viable solution to the global challenge of CO2 storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO2. Under reservoir conditions, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We have monitored the regeneration of H-ZSM-5 via operando time-resolved powder X-Ray diffraction (PXRD) coupled with mass spectroscopy (MS). Parametric Rietveld refinements and calculation of the extra-framework electronic ...
