(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Electrical properties of point defects in 4𝐻-SiC have been studied extensively, but those related to carbon interstitials (Ci) have remained elusive until now. Indeed, when introduced via ion irradiation or implantation, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)As-grown and pre-oxidized silicon carbide (SiC) samples of polytype 4H have been annealed at temperatures up to 1950 °C for 10 min duration using inductive heating, or at 2000 °C for 30 s using microwave heating. The samples ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Direct evidence of N2 formation after annealing of (ZnO)1−x(GaN)x alloys was revealed. N2 was trapped by VZn+Ga-clusters, forming faceted voids along grain boundaries. This study shows that N–N bonding is a competitive ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Ion implantation induced phase transformation and the crystal structure of a series of ion implanted β-Ga 2 O 3 samples were studied using electron diffraction, high resolution transmission electron microscopy, and scanning ...
-
(Master thesis / Masteroppgave, 2023)Kreft er den nest største dødsårsaken i verden, der utvikling av resistens mot ulike kjemoterapeutikum spiller en stor rolle for sykdommens negative progresjon. Forskning og utvikling av nye effektive behandlinger av kreft ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The dynamic response of rocks to thermal, hydrodynamical, mechanical, and geochemical solicitations is of fundamental interest in several disciplines of geosciences, including geo-engineering, geophysics, rock physics, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We quantify the spatial distribution of fracture networks throughout six in situ X-ray tomography triaxial compression experiments on crystalline rocks at confining stresses of 5–35 MPa in order to quantify how fracture ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Igneous intrusions in sedimentary basins can influence basin-scale fluid flow and petroleum systems in various ways. They may act as barriers, preferential pathways or even reservoirs for fluids. The fracture networks of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)At the time of energy transition, it is important to be able to predict the effects of fluid overpressures in different geological scenarios as these can lead to the development of hydrofractures and dilating high-porosity ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The surface morphology of faults controls the spatial anisotropy of their frictional properties and hence their mechanical stability. Such anisotropy is only rarely studied in seismology models of fault slip, although it ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)For the successful implementation of catalysts in industrial processes, three overall goals are optimized: activity, selectivity, and stability. This review will address the role of chemical descriptors in aiding and guiding ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Inspired by the fast digitalization during the Covid-19 crisis, we investigate a key aspect of digital transformation of higher education – the emergence of a digital learning space. In developing our analysis, we focus ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Interpretation of seismic data has played a major role in recent advances in the studies of igneous sill complexes. Seismic modelling studies based on field analogues represent a promising tool to close the scale gap between ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The valorization of CO2 to produce high-value chemicals, such as methanol and hydrocarbons, represents key technology in the future net-zero society. Herein, we report further investigation of a PdZn/ZrO2 + SAPO-34 catalyst ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Extensive carbonation of peridotite results in listvenite, a rock composed of magnesite and quartz. At Gråberget, Røros, SE-Norway, a variably serpentinized peridotite body, surrounded by the Røros schists, a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Transition metal antimonides form a class of intermetallic compounds, which has drawn considerable attention due to their potential applications in various fields. However, the formation of nanostructures containing multiple ...
