(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Policy anomalies are frequent in nowadays’s computer networks due to their increasing configuration complexity. Resolving policy anomalies usually requires network administrator intervention, which is a time-intensive and ...
-
(Master thesis / Masteroppgave, 2023)Depression during pregnancy can be a danger for both mother and fetus. Therefore, treatment is often considered necessary even though pregnant women are often excluded from clinical trials, and the knowledge of the potential ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Understanding fluid flow in rocks is crucial to quantify many natural processes such as ground water flow and naturally triggered seismicity, as well as engineering questions such as displacement of contaminants, the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Cu-Pd-Sn material system has a (Cu, Pd) 3 Sn phase region that shows an interesting and unexplored marten- sitic phase transformation. Literature on this system is limited and the description of the phases present is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Plasmonically active nanoparticles offer a promising pathway to extend the absorption range of photocatalysts. While not necessarily catalytically active themselves, these particles allow the absorption of lower energy ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The authors present research on the electronic transport in heterostructures based on p-type nickel oxide (NiO) with the n-type oxide semiconductors zinc oxide (ZnO) and cadmium oxide (CdO). NiO is a desirable candidate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Cuprous oxide (Cu2O) is a p-type semiconductor with high optical absorption and a direct bandgap of about 2.1 eV, making it an attractive material for photovoltaic applications. For a high-performance photovoltaic device, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Background. Lynch syndrome is the most common genetic predisposition for hereditary cancer. Carriers of pathogenic changes in mismatch repair (MMR) genes have an increased risk of developing colorectal (CRC), endometrial, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Owing to fully occupied orbitals, noble gases are considered to be chemically inert and to have limited effect on materials properties under standard conditions. However, using first-principles calculations, we demonstrate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We have investigated the magnetic structures of the Swedenborgite compound CaBaFe4O7 using magnetic susceptibility and neutron diffraction experiments on powder and single-crystal samples. Below TN1 = 274 K the system ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Crude oil spills are a worldwide ocean conservation threat. Fish are particularly vulnerable to the oiling of spawning habitats, and crude oil causes severe abnormalities in embryos and larvae. However, the underlying ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Fluid-induced alteration of rocks and mineral-based materials often starts at confined mineral interfaces where nm-thick water films can persist even at high overburden pressures and at low vapor pressures. These films ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Since the 1970s, it has been shown that calcium phosphate crystals nucleate from one or several early amorphous calcium phosphate phases into several in vivo and in vitro systems. However, the precise chemical composition, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Alpine glaciers are shrinking and rapidly loosing mass in a warming climate. Glacier modeling is required to assess the future consequences of these retreats on water resources, the hydropower industry and risk management. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Cardiac muscle cells can exhibit complex patterns including irregular behaviour such as chaos or (chaotic) early afterdepolarisations (EADs), which can lead to sudden cardiac death. Suitable mathematical models and their ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)A challenge in converting CO2 into hydrocarbons (HC) via methanol (MeOH) is the gap between the optimal temperature for each step (i.e. ≤250 °C for MeOH and ≥350 °C for HC). The focus of this study is to elucidate the cause ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We herein report on the development of a new prototype PTR-ToF-MS (proton-transfer-reaction time-of-flight mass spectrometry) instrument that combines a hollow cathode glow discharge (HCGD) ion source with a focusing ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Thermoelectric ZnSb has a native surface oxide layer of Sb2O5 +ZnO, while HT oxidation in air resulted in selective oxidation to ZnO, with no detectable Sb by STEM-EDS. The ZnO consisted of an inner nano-granular and a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Non-polar ZnCdO films, grown over m- and r-sapphire with a Cd concentration ranging between 0.8% and 5%, have been studied by means of slow positron annihilation spectroscopy (PAS) combined with chemical depth profiling ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Conductive rutile TiO 2 has received considerable attention recently due to multiple applications. However, the permittivity in conductive, reduced or doped TiO 2 appears to cause controversy with reported values ...
