(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)In this work we benefited from recent advances in tools for crystal‐structure analysis that enabled us to describe an exotic nanoscale phenomenon in structural chemistry. The Mn0.60Ni0.40As sample of the Mn1−xNixAs solid ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The diffusion of saturated and unsaturated hydrocarbons is of fundamental importance for many zeolite-catalyzed processes. Transport of small alkenes in the confined zeolite pores can become hindered, resulting in a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The chalcopyrite Cu(In,Ga)S2 has gained renewed interest in recent years due to the potential application in tandem solar cells. In this contribution, a combined theoretical and experimental approach is applied to investigate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Volcanic eruptions pose a threat to lives and property when volcano flanks and surroundings are densely populated. The local impact of an eruption depends firstly on its location, whether it occurs near a volcano summit, ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The mechanisms triggering intermediate and deep earthquakes have puzzled geologists for several decades. There is still no consensus concerning whether such earthquakes are triggered by brittle or ductile mechanisms. We ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The evolution of electrical resistance as function of defect concentration is examined for the unipolar n-conducting oxides CdO, β-Ga2O3, In2O3, SnO2 and ZnO in order to explore the predictions of the amphoteric defect ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A 2D Hele-Shaw cell was built to study microfracture nucleation, growth, and network formation during internal fluid production. Fluid is slowly produced into a low permeability solid, which leads to a local fluid pressure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Reaction-infiltration instability refers to the morphological instability of a reactive fluid front flowing in a soluble porous medium. This process is important for many naturally occurring phenomena, such as the weathering ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Abstract Stool samples for fecal immunochemical tests (FIT) are collected in large numbers worldwide as part of colorectal cancer screening programs. Employing FIT samples from 1034 CRCbiome participants, recruited from a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)[FeL2]X2·2H2O (L = 2,6-bis{5-methyl-1H-pyrazol-3-yl}pyridine; X− = BF4− or ClO4−) are readily dehydrated upon mild heating. Anhydrous [FeL2][BF4]2 exhibits an abrupt spin-transition at T1/2 = 205 K, with a 65 K thermal ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Selective reduction of CO2 is an efficient solution for producing nonfossil-based chemical feedstocks and simultaneously alleviating the increasing atmospheric concentration of this greenhouse gas. With this aim, molecular ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Patients with bipolar disorder (BIP) have a high risk of cardiovascular disease (CVD), despite considerable individual variation. The mechanisms underlying comorbid CVD in BIP remain largely unknown. We investigated ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)In this study, we fabricated a planar Si/PEDOT: PSS heterojunction solar cell using three different solvents—ethylene glycol, acetonitrile, and dimethyl sulfoxide—to find the best one. The fabricated samples were characterized ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Water adsorption and surface protonic conduction have been investigated at 25–400 °C in wet (H2O and D2O) atmospheres on nanocrystalline TiO2 hydrothermally grown to a predominance of different crystal facets. In situ ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Dissolved Natural Organic Matter (DNOM) is a heterogeneous mixture of partly degraded, oxidised and resynthesised organic compounds of terrestrial or aquatic origin. In the boreal biome, it plays a central role in element ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Rising organic charge in northern freshwaters is attributed to increasing levels of dissolved natural organic matter (DNOM) and changes in water chemistry. Organic charge concentration may be determined through charge ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The COVID-19 pandemic has exemplified the importance of interoperable and equitable data sharing for global surveillance and to support research. While many challenges could be overcome, at least in some countries, many ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Deriving reliable information about the structural and functional architecture of the brain in vivo is critical for the clinical and basic neurosciences. In the new era of large population-based datasets, when multiple ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Laboratory measurements can determine the potential for geologic materials to generate unstable (seismic) slip, but a direct relation between sliding behavior in the laboratory and physical characteristics ...
